  • Smart foot position sensor for power wheelchair users, and systems and methods of using same
    Patent number: 11083652
    Abstract: Disclosed herein is a footplate assembly for monitoring foot position in real time, as a wheelchair is driven. Optionally, the footplate assembly can use an array of force-sensing resistors and infrared distance sensors to detect the pressure and location of the foot within the immediate confines of the footplate. The footplate assembly can be provided as an overlay to an existing wheelchair footplate structure, or the footplate assembly can be integrated into or replace an existing wheelchair footplate structure.

  • Method and System for Collecting, Normalizing, and Analyzing Spend Data
    Publication number: 20090100017
    Abstract: A system for processing spend data. In response to capturing data feeds from one or more clients and a service provider, spend data contained within the data feeds is normalized by mapping the spend data to a common universal taxonomy using a business rule set. The normalized spend data is stored within an aggregated spend database. Report queries are run against total aggregated spend data within the aggregated spend database. Then, results of the report queries are posted on a secure web portal for viewing by authorized users.

  • User modifiable fuel injection computer
    Patent number: 5056026
    Abstract: A user accessible electornic fuel injection system is disclosed which is modifiable to fit a range of engine configurations, preferably with a staged fuel injection curve and with the capability of recording speed, fuel delivery rate and other engine performance parameters. The system includes computer software which directly controls the fuel injection hardware in an automobile. This software contains a serial communication routine which services the external requests of a control program running on a personal computer, plus engine management software which controls timing functions based on engine related information.
