Towards Ultra Low-Cost Myoactivated Prostheses

Ultra Low Cost Linear Testing

The advent of high quality PC based instruments, combined with the normal day to day skills of linear test engineers, eliminates the need for general purpose linear testers in many cases. Linear applications are dominated by custom DUT boards; therefore a few application card tricks and some PC instruments can replace the general purpose linear tester and significantly reduce cost and size with...

Ultra-Low-Cost Printed Electronics

Low-cost Ultra High Isolation SPDT Switch

Wide-band test instrumentation often needs signal routing. This is accomplished with mechanical switches, which are expensive and slow. When isolation requirements are not high, it is also done with electronic switches. Some high isolation switches available in the market are very expensive. Mini-Circuits has developed a pair of low-cost, high isolation, fast switching, TTL-driven, connectorize...

Towards a Safe, Low-Cost, Intelligent Wheelchair

Unlike most other robots, autonomous personal transports must be designed with a passenger user in mind. This paper examines the integration of three necessary technologies for a robotic transport—in particular, a robotic wheelchair. First, local motion to a nearby goal pose needs to be safe and comfortable for the human passenger. Second, 3D overhangs, drop-offs, steep inclines, and stairs (in...

Towards a Low Cost Etl System

Data Warehouses store integrated and consistent data in a subject-oriented data repository dedicated especially to support business intelligence processes. However, keeping these repositories updated usually involves complex and time-consuming processes, commonly denominated as Extract-Transform-Load tasks. These data intensive tasks normally execute in a limited time window and their computati...
