Hydraulic-Based Spherical Robot
Current spherical robots rely upon rotating mechanical weights inside the sphere to change the center of gravity of the sphere, causing the robot to roll. The use of rotating mechanical weights is not optimal due to the reliance upon moving parts, which can present burdensome maintenance issues. It would be...

Power Outlet Analyzes Electrical Current Usage
Electrical interruptions, or “nuisance trips,” occur when a detector installed behind the wall trips an outlet's electrical circuit when it senses something that could be an arc-fault — a potentially dangerous spark in the electric line. The problem with today's arc-fault detectors is that they...

Microcontroller Altimeter (uCA)
Traditional altitude switch designs for harsh environments are mechanical in nature and operate by means of an inflatable bladder or bellows that mechanically depresses a pushbutton switch. The altitude trip point is set by mechanically adjusting the distance of the switch to the bellows. The mechanical action of the...

The most common methods for glucose self-testing involve monitoring glucose levels in blood. These conventional measurements are not suitable for preventing hypoglycemia during exercise. The underlying...
Briefs: Sensors/Data Acquisition
An effective, non-invasive way of monitoring blood glucose could help both diabetics and those at risk of developing diabetes make the right choices to either manage the disease well, or reduce their risk...
Briefs: Communications
An increase in computing performance has been achieved by squeezing ever more transistors into a tighter space on microchips. This downsizing has also meant packing the wiring within...
Briefs: Electronics & Computers
Adhesives used for common pain-relieving bandages often do not stick properly when attached to places that encounter large, inhomogenous bending motion, like elbows and knees. To solve...
Briefs: Sensors/Data Acquisition
Spintronic devices promise to solve major problems in today's computers, which use massive amounts of electricity to generate heat. This requires expending even more energy for cooling. By contrast, spintronic...
