Hillcrest Labs believes sensor hubs will be all the rage in consumer electronics this year and will be seen in mobile, wearable and Internet of things (IoT) devices. Let’s explore why. The latest generation of smartphones uses sensor-based functionality such as motion gestures as key differentiating features.
We are currently experiencing the first phases of the Smart Home with much more to come as the Really Smart Home finally becomes a reality. The adaption of ZigBee remote controls and ZigBee set top boxes by most of the world’s cable TV and broadband service providers is the launching platform for the rolling out of various Smart Home-Connected Home services....
The December issue focuses on Test and Measurement and the challenges in the community when it comes to the push in the consumer market for faster, smaller, better electronics. The cover story focuses on predicting end-of-life for future mobile devices and is accompanied by a story exploring the options for reducing the effects when the systems do fail. The issue also featured our first OnDesign column by our newest writer Joshua Israelsohn who focused on Smart Grid technology.
Portable devices such as cell phones, MP3 players and tablets have become popular over the years. Most people own at least two of these devices. Each device requires a power adapter to charge and provide power for these portable electronics.
All electrical systems, including computers, entertainment systems, mobile phones, medical instrumentation and automotive electronics, need to be immune from damage due to electrical transients encountered on a day-to-day basis. Electrical transients can come from many sources.
Detecting counterfeit electronic components is not easy — if it was, our industry would not be suffering the $160 billion in annual risk identified by IHS Research. The industry is being forced to take action, with recent federal legislation setting an example for the entire supply chain....
A large number of legacy industrial PCs (IPCs) are still deployed in active control and monitoring roles. Most of these IPCs are running older, out-of-support operating systems such as Windows 2000 or XP. Microsoft Windows 2000 support expired July 2010, and Windows XP support ends April 2014.
Albert Einstein said, “Everything should be made as simple as possible, but not simpler.” Whether in architectural design, software coding, engineering discipline or even managing people, simplicity is an overriding goal and success is achieved when a product or process is at its maximum simplicity.
How test instrument manufacturers can design to meet the expectations of new and experienced engineersOctober 14, 2013 2:36 pm | by Jonathan Tucker, Keithley Instruments, Inc. | Articles | Comments
A recent industry study indicates one out of five electrical engineers now in the global workforce has started his or her career within the last 10 years. These newer engineers tend to be more software-oriented than some of their more experienced colleagues due to recent changes in universities’ electrical engineering curricula.
JTAG/Boundary Scan has become an increasingly valuable application, in particular in the development departments of small and large companies. On the one hand, this is due to the enormous potential the technology provides and, on the other hand to the problems increasingly compact assemblies and components place on test technologies with respect to mechanical access.
Wind River introduced the latest version of Wind River Intelligent Device Platform, a complete software development environment used for building machine-to-machine (M2M) applications and devices that communicate with the cloud. The platform provides ready-to-use components to secure, manage, and connect Internet of Things (IoT) gateways.
The need for seeing additional current and voltage detail is increasing. Many scope users want better ability to see small signal changes on a large signal (high dynamic range measurements). Power rails, biomedical technology developed to interact with human physiology, high-energy physics experiments that produce small pulses....
Electronic systems, both analog and digital, are processing and managing increasing amounts of information at continually increasing data rates. The information age continues to amplify demands on developers of high accuracy and reliability systems and subsystems.
Solid-state lighting is now becoming commonplace in automotive designs, replacing more costly, less energy efficient and not as reliable incandescent lamps. Though it is only in recent times that it has started to be considered for the parking lights, brake lights, side lights and front lights on the car’s exterior...
You can improve contrast and reduce motion blur by sequentially flashing zones in an LCD display that is back lit with edge-mounted LEDs. You achieve this scrolling illumination with improved LED driver ICs. With the help of some timing diagrams this article will reveal how this works in principle and will give a description of the different modes of operation.
Transformers are widely used in electronics and power, so it is important to have an understanding of how transformers work, what they are composed of and test and analysis techniques. The most common type of transformer is called an AC input line, or Mains transformer.
Measuring temperatures using infrared (IR) sensors without direct contact with an object, is the new paradigm in optimizing thermal monitoring and control. In this article we introduce the idea of this approach by taking advantage of new and very small IR temperature sensors available on the market.
Whether it’s a high-rise office tower or a manufacturing floor, Heating, Ventilation and Air Conditioning (HVAC) systems are designed for building occupants’ comfort. When systems operate at optimum levels, they’re energy efficient and go unnoticed. When they’re not, efficiency drops and complaints rise.
Perhaps no business service is more critical than telecommunications; reliability and quality of a phone system are absolute requirements. Over the past decade, internet-based VoIP (voice over internet protocol) has taken its place as a viable means of communication for individuals....
Two industry megatrends are reshaping the way we design and deploy networks and compute (i.e. datacenter servers). The first is Network Functions Virtualization (NFV) with the goal of moving functions such as content distribution, firewalls and base station controllers from proprietary hardware to standard, low cost servers.
Light sensing technology, in the form of photodiodes and phototransistors, was invented around the 1950s. Since the inception of the first optosensors, the devices have gradually found their place in commercial and industrial applications, but their adoption was limited due to the size, cost and overall performance.
Field effect transistors (FETs) are important semiconductor devices because they are fundamental components of many devices and electronic instruments. Some of the countless applications for FETs include their use as amplifiers, memory devices, switches, logic devices, and sensors.
Sensors have been an important addition to smartphones ever since accelerometers were first used to determine screen orientation. Now a wide variety of sensors, including magnetometers, barometers, and gyroscopes, are found in many other devices, such as watches, glasses, headsets, and shoes.
New construction materials and techniques enable LVDT linear position sensor operation in diverse environmentsApril 30, 2013 3:04 pm | by Lee Hudson, Applications Engineer, Macro Sensors, www.macrosensors.com | Macro Sensors | Articles | Comments
The LVDT Linear Position Sensor is a robust sensor adaptable to a variety of applications. A very reliable sensing device with no moving parts, LVDTs are often the best linear feedback technology when it comes to reliability and longevity. However, in the past, LVDTs were limited by its own sensitivity to the environment that caused errors in linear feedback.
Accurate measurement of low pressure with respect to atmospheric reference (typically called vented or gauge reference) requires that pressure sensors breathe under dry, humid and wet conditions. In humid and wet environments, challenges are posed on how to operate the pressure sensor without allowing water into the back end of the sensors....
