Extending the Human-to-Machine Interface (HMI) using wireless communications is a fast developing field. Important improvements in HMI functionality have been made possible by continuing advancements in Machine-to-Machine interfaces in terms of increased baud rate, low power consumption and reach (distance) of communication.
Electronic medical systems have become substantially more sophisticated and powerful in recent years. As a result, the majority of these systems contain large arrays of power hungry electronic components that require high-performance heat sinks to prevent them from overheating and being damaged or destroyed.
The personal computer (PC), currently the standard information-processing device for office and home use, communicates with most peripherals using the universal serial bus (USB). Standardization, cost, and the availability of software and development tools have made the PC very attractive as a host-processor platform for medical and industrial applications...
An Electronic Engineer builds a system out of components; resistors, ICs, MOSFETs and IGBTs. The Power Electronic Engineer has to go beyond the electrical parameters of components and start looking at thermal resistance and capacity, cooling and parasitic inductance.
The statistics vary, but all seem to be in agreement that nearly 30 to 40% of the present load base on the grid is caused by induction motors
Building It Up/Breaking It Down with iSuppli provides a quick look inside the latest products, highlighting some of the components used. Today we take a look inside the Apple iMac Desktop Computer.
As the semiconductor industry has grown dramatically over the last 30 years, so to has the counterfeiting of semiconductors.
There are many applications whose operating environments demand the use of an interconnect system with a high-reliability contact. If equipment is to be used where high shock and vibration or extremes of temperature are experienced, connectors based on a standard contact will not be reliable or rugged enough to guarantee signal integrity.
Handheld electronic devices -- regardless of what they are used for or who manufactures them -- share one common denominator: a re-chargeable battery and, in most cases, a built-in charger circuit. When an external power source such as an AC adapter or a USB port is attached at the input terminal, the charger circuit will re-charge the battery.
How can we make solar panels more efficient?
What is the next breakthrough in battery technology?
Microcontrollers offer engineers a variety of power-saving techniques. But using them effectively requires careful attention to tradeoffs in software and hardware at the start of a project. "Engineers must partition their application so they have a rough idea how long their microcontroller will stay in a sleep mode or in an active mode," said Mike Salas...
To find out more about the state of motor-control design in embedded systems, I recently talked with three engineers at Texas Instruments who work with motor-related hardware and software. "Motor control looks simple to start but it covers many disciplines so it's almost impossible to have one designer do everything," noted Miroslav Oljaca...
The continued increase in mobile handset functionality is being enabled by more powerful baseband and applications processor chips, which are more frequently coupled with memory devices using package-on-package (PoP) stacking.
The emergence of energy-efficiency standards and continued evolution of processing and feature sets to support new products that consumers/enterprises use in everyday life: DVRs, set-top boxes and modems, industrial handhelds, portable media players, bar-code scanners have changed the methodologies employed for addressing DC power conversion, management and distribution.
