Engineering a Paradigm Shift in At-Home Monitoring Devices
Posted in Treatment Devices, Electronics & Computers, Electronics, Medical, Patient Monitoring, Features, MDB on Wednesday, 01 June 2011
Semiconductor vendors are constantly on the lookout for the market dislocations that will provide the opportunity for product innovation and subsequent sales and revenue growth. Market dislocations tend to be anticipated and debated long before they come to fruition — echoing the old adage that invention is 10 percent innovation and 90 percent perspiration. Today, the healthcare industry is on the cusp of a market dislocation that promises to change the way healthcare is administered.

Experimental Walking Assist Device With Body Weight Support System
Posted in Bio-Medical, Electronics & Computers, Electronics, Rehabilitation & Physical Therapy, Medical, Briefs, MDB on Wednesday, 01 June 2011

This technology is designed for users who, though capable of walking on their own, would benefit from a reduction of load on their leg muscles and joints.

An experimental walking assist device has been developed to help support body weight and reduce the load on the user’s legs while walking, going up and down stairs, and in a semi-crouching position. The device reduces the load on leg muscles and joints (in the hip, knees, and ankles) by supporting a portion of the person’s body weight. It features a simple structure consisting of seat, frame, and shoes, and the user can put it on by simply wearing the shoes and lifting the seat into position. Moreover, a mechanism that directs the assisting force toward the user’s center of gravity and the ability to control the assist force in concert with the movement of the legs make it possible for the device to provide natural assistance in various postures and motions.

Electrocardiography (ECG) Necklace
Posted in Bio-Medical, Patient Data Management, Treatment Devices, Electronics & Computers, Electronics, Medical, Patient Monitoring, Briefs, MDB on Wednesday, 01 June 2011

Wearable monitoring system uses an ultra-low-power application-specific integrated circuit and a beat-to-beat detection algorithm to measure cardiac activity.

Integrated wearable monitoring systems based on body area networks (BANs) enable continuous, reliable, and long-term monitoring of physio- and biological signals on the move, leading to wearable health solutions for next-generation healthcare, wellness, and lifestyle. An electrocardiography (ECG) necklace has been developed to target the simultaneous monitoring of cardiac and physical activity in everyday life situations.

Real Time Operating System
Posted in Electronics & Computers, Electronics, Software, Products, MDB on Wednesday, 01 June 2011
The ThreadX® RTOS from Express Logic (San Diego, CA) is designed for microcontroller-based applications and features a memory footprint as small as 2 KB to reside on limited on-chip MCU memory. It provides pre-emptive, real-time, priority-based scheduling for optimum responsiveness and includes services such as thread scheduling, message passing, resource allocation, synchronization, and interrupt management. It incorporates Preemption-Threshold™ technology that can be used to minimize context switches, while still maintaining system schedulability.

Push-to-Connect Fittings
Posted in Electronics & Computers, Electronics, Products, MDB on Wednesday, 01 June 2011
NewAge Industries (Southampton, PA) offers Newloc® push-to-connect fittings in acetal copolymer and brass. Both allow quick connections to rigid and semi-rigid tubing such as nylon, polypropylene, and polyethylene. Typical applications include pneumatic control systems, robotics, instrumentation, and chemical lines. The fittings offer leak-proof connections with no flow restrictions, as well as a full vacuum rating (29.9 in/Hg). The plastic (acetal) Newlocs are suitable for pneumatics, while the brass Newlocs handle temperatures up to 200 °F.

LED Mounting Spacers
Posted in Electronics & Computers, Electronics, Mechanical Components, Products, MDB on Wednesday, 01 June 2011
Keystone Electronics (Astoria, NY) has introduced a series of self-retaining, T-1 LED mounting spacers designed to assure uniform and perpendicular LED positioning. The spacers feature internal retention “teeth” that secure spacers onto LED leads, prior to assembly on PCBs. The design also eliminates the possibility of LED lead shorting by separating and retaining component leads while inserting into a PCB. The spacers feature 0.020" legs incorporated into the molded Nylon 6/6 structure to serve the dual purpose of heat dissipation and easy post-solder cleaning. Overall height of the spacers ranges from 0.120" to 0.925".
