In the past, 30 years ago, I use tapes to record audio. Now, everything is changed, and the digital era brought us new devices.

A voice logger is an instrument used to record audio from radios, telephones, and other infectious devices and store that information in a computer’s hard drive or any removable media. There are generally two modes used for recording, and they are vox mode and non-vox mode. Vox Mode is the mode where the voice is activated, and the non-vox method is that mode where recording is done continuously.

Voice logger is a system that is generally used by call centers and other businesses. It may be also used for emergency services. These records are kept safely and are used by security organizations and sometimes private firms too. The legality of these recordings may sometimes become a question. 

 Voice logger is one of those devices that is used by officials as well as businesses too. The companies may use voice logger for improving their customer services. The features that are being provided keep each thing in mind about business. The updated version of voice loggers has advanced features, flexible, and is easy to use. These quick enhancement increases the productivity for the company and helps to attain customer satisfaction. 

 History of Voice Logger

 The voice loggers have become significantly updated these days, but early in the 1990s, the voice logger recorded the audio using a codec and stored in a digital tape. With changing times, the voice loggers also change, and now the recorded calls are stored in a file or a hard drive. 

Below is example of installation of voice logger:

The first and original voice logging device was made or developed by Magnasync in 1950. It soon gained popularity, and by 1953, Magnasync Corporation sold about 300 voice loggers to the United States Air Force. Over the year, the loggers were manufactured by Arcane Logger, ASC, Comverse, Cybertech, Dictaphone, etc. By the passing of the years, there have been many changes in this field, and the master vendor of the loggers includes ASC, Exam, Red Box, etc. 

 The Types of Voice Loggers

1)   Analog Tape – It is the oldest model and was recorded by catching and storing the reel. The cassettes or microcassette is a part of these recorders. 

2)   Digital Tape – These are some of the most used or standard recorders used today. They store and also have detailed metadata relating to calls or other. 

3)   Software Only Systems – These system recorders are all software running. It may record the audio on hardware. This type of software usually records a single line at once and are limited in features than others. 

Uses of Voice Logging 

 There are not one but many uses of voice logging. Some of them are discusses –

1)   Financial Institutions Such as Banks – Many banks all over the world have made call recording permanent. Stocking broking firms are also asked to do the same. The tapes provide quick access to voice files if any dispute occurs, and this saves a lot of time. 

2)   Call Centres – Voice logging is also used by call centers to keep a check on customer services and the agent’s behavior on the call. This also helps these centers to improve their services and solve the queries of the customer quickly. 

3)   Business Enterprises – As discussed above, businesses also use voice logging. It may be used in a real estate firm or by some media house. It helps the companies keep the records of all the calls and quickly check for queries. 

4)   By Tourism, Hotels, Railways, etc. – This helps record all the calls such as the case of railways, they record the information related to reservations. Voice logging adds efficiency in the work and increases the effectiveness of the staff. 

5)   Health Care Sectors such as Hospitals, Clinic, and Pharmacy – Voice Logging here help hospitals or pharmacy by keeping a record of verbal prescriptions. This allows the staff to save the patient’s inquiries on the phone. 

6)   Educational Institutions – Educational Institutions such as schools and colleges keep records of all the details made on the call. Recording may help these institutions to have feedback. It also provides a bridge for them on how to improve the conversation or communications between the customers and their staff.

Oscilloscope definition

An oscilloscope is a laboratory device that is used to display and analyze waveforms of electronic signals. The effect of the signal voltage is drawn in the shape of a graph. An oscilloscope can display Alternating Current(AC) and Direct Current(DC). The frequency should be as low as 1 hertz(Hz) or in several megahertz(MHz). There is also another type of oscilloscope known as the High-End Oscilloscope. These oscilloscopes can display the signal frequencies of up to a hundred gigahertz(GHz).

Oscilloscope Effect
The Oscilloscope Effect represents the process when the oscilloscope draws a graph of the instantaneous signal voltage as a function of time. Using this effect, researchers can read and analyze the waveform of electronic signals.

The display of the oscilloscope is divided into two parts, i.e., Horizontal Divisions and Vertical Divisions. The horizontal scale displays time from left to right while the instant voltage appears on the vertical scale. The positive value of the voltage on the vertical scale goes upwards while the negative goes downward.

The oldest model of the oscilloscope is still used in some of the labs and is known as Cathode-Ray Oscilloscope. In these, the image is produced by focusing the electron beam: the modern or electronically built oscilloscope copy the CRT’s action by a liquid crystal display.

On an oscilloscope, roll mode or cyliscope mode is a method of displaying acquired waveform data without waiting for the complete waveform record.

The measurements in any of the oscilloscope is measured in per seconds(s/div), milliseconds per division(ms/div), microseconds per division(s/div), and nanoseconds per division(ns/div) on the horizontal sweep whereas the vertical deflection is measured in volts per division(V/div), millivolts per division(mV/div) and microvolts per division(?V/div). All the oscilloscope have horizontal sweep and vertical deflection adjustments.

A new sort of digital device is now available that is known as a high-end oscilloscope. Since they are digital devices, they can connect to computers and can use their display. These machines now no longer scan beam for generating images of the waveform. The basic principle of this device also remains the same as traditional. The digital oscilloscopes have software embedded in them that controls the sweep rate and vertical deflections. Apart from this, some other features include storing waveforms for future references, displaying several waveforms, analysis, and others. 

Sizes of the Oscilloscope

The modern and most commonly used oscilloscope is lightweight and can be easily carried by a single person. The laboratory used oscilloscopes that have vacuum tubes are bench-top devices or mounted on dedicated carts. The oscilloscopes that are used for special occasions are rack-mounted or have permanent mounting. 

Some types of Oscilloscope

1) Dual-Beam Oscilloscope – The dual beams are the oscilloscopes that can display the two signals. A particular CRT generates and deflects two separate rays. There is also some disadvantage of this oscilloscope, i.e it cannot be switched quickly between the traces and could not catch the two events. 

2) Analog Storage Oscilloscope – Analog scopes have extra features such as they have trace storage. They use the direct-view storage CRTs. 

3) Mixed Signals Oscilloscope – They generally have two kinds of input, i.e., a small number of analog channels and many analog channels. It has a unique feature to time-correlate analog and digital channels. In a Mixed-Signal Oscilloscope, the trigger can be easily set on both the analog and digital channels.

4) PC Based Oscilloscope – They are digital oscilloscope and rely on PC for display and control. It can connect with the USB or LAN to separate PC or Laptop. 

Other Instruments 

There are many instruments used in technical fields and are oscilloscope having inputs, calibration controls, displays, etc. They are specialized and optimized for a particular purpose. The fine example of such oscilloscopes includes waveform monitors for reporting video levels and medical devices such as electrocardiograms. 

 They are also used in different industries, and each has a vital role in that field. The oscilloscope is the device that has its value, and that cannot be ignored. Even in the automobile industry, an ignition analyzer is used to show the spark waveforms for every cylinder.

The process of developing backup systems to secure data in a virtual location during an unprecedented event of a disaster is referred to as Virtual Disaster Recovery. It’s a strategic approach to developing a system that supports DR Virtualization of servers reflect saving of the server data in a VM independent of the physical hardware at any location.

The requirement of physical servers at the primary site is different from the secondary site.

How does virtualization help data protection and disaster recovery?
Virtualization help data protection and greatly simplifies disaster recovery because it does not require rebuilding a physical server environment. Virtualization consolidates the entire server environment, all systems, workstations into a single virtual machine. Any computer system can be virtualized such as data storage, workstations, networks, and applications.

What are the benefits of Virtual Disaster Recovery?

The physical server and handling of information require effort and consistent expenditure for maintenance. The virtualization of data on physical servers makes it easier, fast, and efficient system of systemizing information.

Virtualization makes recovery point objectives and recovery time objectives feasible and quicker. Often, in the case of disasters like floods, earthquakes, and fires, the data becomes susceptible to lose in physical zones. The virtualization of the data makes it possible to reach any information irrespective of the physical location.

Installing VM’s is a very complicated task, once installed organizations need guidelines for strict sprawling. The larger companies with many employees have loose communication skills. Rigorous knowledge of DR is necessary to maintain the system in place. Strict guidelines must be set to deploy VM technology.

Building and testing Virtual Disaster recovery

Virtual infrastructures are highly complexed, and recovery from them during an unplanned event is a necessary part of a DR plan.

A virtual disaster recovery plan is very similar to the conventional DR plan. Some critical points for virtualization are:

1. Analyze the system and document essential information.
2. Get the DR plan approved by the management.
3. Write down the steps for recovery.
4. Identify RPO’s and RTO’s.
5. Check the project and assign roles.

Once, you are done sketching the plan, make sure the staff knows what they have to do in an actual unplanned incident.

The organization’s virtual disaster recovery plan should be reviewed and updated at a different period to keep it relevant in case of a change in the environment. The physical and virtual system requires evaluation regularly. It’s an essential practice for the business community.

How is Virtual Disaster Recovery different from Physical Disaster Recovery?

Virtual Disaster Recovery is simple and includes only simple clicks. The standard practice involves checking RTO’s and RPO’s. The traditional data recovery process is complex; on the other hand, virtual data recovery is a few clicks process.

Recovery in the virtual world is more accessible than in the physical world. Creating DR in a virtual set up is more manageable and does not affect overall productivity.

Experts recommend keeping sensitive data offline or printed. However, the providers always equip with safety against cyberattacks, ransomware, and taping of sensitive information.

Future Prospects of the Virtual Disaster Recovery

1. Ransomware is a significant threat to businesses nowadays. Organizations are utilizing explicit techniques to avoid losses. The point-in-time copies feature aggressively brings back the data to just before the attack.
2. Instant Recovery – The backup snapshot of the VM runs continuously on the backup storage. It’s an important technique to reduce RTO’s.
3. Hyperconvergence – Fusing storage, virtualization, and computing is a highly in trend strategy to protect losses from suspicious stealing and ransomware.

Every day enhancing technologies and new vendors like Rubrik and Cohesity are taking charge and pushing possibilities to another level.

Prominent Data Vendors offering disaster recovery and virtual backup

1. Nakivo Backup and replication for AWS compute cloud, VM-ware, Microsoft Hyper-V.
2. Acronis Disaster Recovery solutions.
3. Solarwinds backup
4. Zerto’s flagship Virtual Replication
5. Veeam software protects VM’s and has multiple solutions for physical and virtual data storage-recovery.

The food management industry covers a broad spectrum of tasks that presents in form of multiple career options for the aspirants. When people hear the word ‘food management’, the first thing that comes to their mind is the ‘food service’ sector. The food or catering service depends upon several types of managers that supervise every part of food management.

Food management is an extensive process that ranges from food selection and its preparation to food arrangement, display, and preservation. The food managers ensure that any served or sold food’s taste, quality, and safety meet the standards set by the local authorities. The basic duty of foodservice professionals is to ascertain that every food sold to individual consumers and businesses comply with the quality regulations.

Given below is an overview of different aspects of food management overseen by various professionals:

• Food Inspection & Processing

Food inspectors are tasked with guaranteeing the cleanliness of preparation facilities. They need to see that the raw, as well as packaged food, are stored at an appropriate temperature and in safe areas. Further, they make sure that the food is not contaminated and checked for any kind of damage before being shipped or delivered to the waiting customers.

Restaurants are required to stick to the prescribed standards and criteria of quality. In addition to verifying that the packaged food is prepared as per the stated standards, the inspectors also ensure that it is set for delivery in a way that will not deteriorate its freshness en-route to the final destination. Even on delivery, other similar supervisors inspect the delivered food products to make sure that there was no damage during transport. Their sole purpose is to assure the freshness and quality of food.

Below is example of food management planning, cost calculation:

Foodservice inspectors work in food processing and manufacturing plants.

• Food Display & Presentation

Food presentation and arrangement is one of the neglected aspects of food management in many areas of the world. Yet it is seen as an essential thing in educated and prosperous communities. The steps to food preparation and food organization go hand-in-hand as a part of the food management process. Here comes the role of food manager who knows how and where the food should be kept. This expert manages the commercial kitchen in the best possible manner, directs the efficient storage of food, and evaluates the freshness of food before its usage in the preparing cuisines. This manager may be at the position of chef in a local restaurant or a part of the hospitality management team in a hotel. Chefs prepare food or a part of it that is added to various dishes.

Generally, the entire kitchen staff is regarded as a crucial part of this management team since the tasks of all these revolve around food and its preparation.

Other Facts about Food Management

People involved in food management need to be well-versed with the correct methods to wash their hands. Besides the restaurant and hotel jobs, food management includes the task of confirming that any expired food is not put up for sale in supermarkets.

Today, almost every food product carries stamps stating the date by which it must be consumed. Manufacturers of items like packaged cereals commonly send their quality inspectors to assess the displayed products in supermarkets. These inspectors need to assure that the food items are well within their written dates. This way, manufacturers know that only fresh food is available to customers. The expired food is not just harmful to eat but also lacks its characteristic taste. In some cases, stale food develops a foul taste and an unnatural appearance.

So, anyone who helps and does the work of food preparation or presentation is said to be a part of the food management team. Even at households, the people who cook or help in the process are responsible for checking the food quality. They usually dispose of the expired food and intend to prepare recipes that appear pleasing as well as taste good. Apart from preventing the adverse effects of expired food, special attention is given to each food item’s presentation and preparation to make it delicious and healthy to eat.

Importance of Food Management

The food management process is critical to safeguarding the quality, safety, and taste in cooking meals that are offered to the public. A proficient food manager is aware of evaluating the freshness of food. Similar experts also oversee the preparation of beverages and drinks at clubs and bars. Some others have the job of keeping an eye on the sources of raw food produce. Effective food-management ultimately leads to favorable consumer experience and thus, has a long-term impact on food sales.

Abiding by Islamic Laws, Halal Gelatin is a type of gelatin which doesn’t contain any Pig based products.

Halal Gelatin performs similar functions like normal pig-based gelatin and is a crucial aspect of foods, cosmetics, clothing and etcetera.

In Islam, there is a stringent set of rules regarding the slaughtering of animals. Since Gelatin is extracted from the bones and skins of Pigs, it is a major highlight for the Halal Diet.

Moreover, as a large number of desserts and other food products contain Gelatin, the Halal Status is an important point for Muslims.

Nonetheless, if the product is specifically stamped as Halal, it gets easier for a Muslim to purchase products without having any doubt.

On the other hand, Muslims can opt for vegetarian-friendly gelatin to stay true to the rules by Islamic Dietary Laws.

In today’s era, many producers have converted their methods of production for increasing the acceptance of their products to the Muslim community.

Another lucrative alternative is to purchase Gelatin from specific producers who sell Halal Gelatin products without any pork contamination.

Although Halal gelatin products are limited, they are being researched for mass-production.

Have you noticed the rubber-like material when you hold a cable? Usually, it is black in color?

Yes, that’s a Cable Sheath!

A Cable Sheath is used to protect the inner conductors and prevent us from electrocution. It can have both single and multilayers of insulating material.

What are the advantages of a Cable Sheath?

• If there are multiple wires, a sheath joins together the conductors inside a cable.

• Intact Cable Sheathing also prevents rain, snow, and other environmental hazards from damaging the cable.

• It reduces the risk of accidents from short-circuits.

• It safeguards passerby/ workers by minimizing the chance of direct contact with an energized cable.

Numerous types of Cable Sheaths are available in the market and are equipped to handle varying degree of voltages and settings. The heavy-duty sheathing is meant for high voltage power lines like outdoor environments and power plants.

On the other hand, sheathing for low voltage lines includes phone wires and thermostats which doesn’t pose a significant risk and is used in a relatively tamer indoor environment.

Over time, cracks and creases can develop in Cable Sheaths.

Such consequences can be a result of weathering or erosion.

How to detect such cracks/ creases?

 Fault checkers can locate the hideous cracks/ creases in a Cable Sheath. In some cases, it may be possible to fix the sheath, while in other cases, lengths of the cable need to go for replacement.

How to technicians are able to repair a Cable Sheath?

Technicians utilize specialized tools to cut through the Cable Sheath and access the inner portion for splices, repairs, and other activities. Keeping in mind the safety, the tool is equipped with a non-conductive handle in case the cable is energized during on-going work. Such tools can be purchased from industrial electrical suppliers.

Any chips which are prepared, seasoned, and served according to Islamic Law are known as Halal Chips.

Although Islam is a religion, its rules and regulations are highly related to food consumption.

Islam doesn’t entertain consumption of Pork or any Pork-based products.  

Meats which are slaughtered according to Islamic tradition are only permissible.

Therefore, chips/ snacks are to be fried and seasoned in separate pans.

It cannot be prepared in utensils that may have come into contact with Pork or a slice of Non-Halal meat.

In general, there are no problems with Chips.

But where does the problem lie?

In many establishments, Pork Fat is a common frying agent for crisps/French fries.

In order to be Halal, Chips must be fried in oil that has its derivation from plants.

Example: Sunflower Oil or Vegetable Oil

Or else, the oil needs to be sourced from a Halal Butcher or Processor.

In addition, the fryers used must have never touched Pork or any Pork-based products.

Similarly, in the case of seasonings and flavourings, Chips cannot be garnished with products that contain Pork or Pork Products.

If any other animal products are utilized, it typically must also be Halal for the meal as a whole to comply with the law.  

It also must not come in touch with machinery that is tainted with such products.

It is always advisable to check the  label or ask the manufacturer for clarification

Usually, preparation of Halal Chips turns out to be more expensive for restaurateurs.

To meet Islamic standards, manufacturers/ restaurateurs needs to use separate machines for Halal and Non-Halal Chips. Additionally, they also need to separate hip-scoops, baskets, and cutlery to avoid contamination.

Undoubtedly, all these considerations escalate the cost of production and give rise to complications.
