Patent number: 9441624Abstract: A sensor system for sensing liquid level in a bilge, for use in automatic bilge pump actuation. First and second field effect sensors are potted or sealed within a container or the bilge wall and are aligned in a vertical array and each comprise a substantially planar pattern of “electrodes” or conductive traces disposed on a printed circuit board (PCB) along with integrated circuits used to create a loop or arc-shaped electric field. As bilge liquid rises to the proximity or level of the field effect sensors, a change in the arc-shaped electric field is sensed and, in response, a bilge pump is automatically actuated to pump liquid out of the bilge. Optionally, the pump control can be programmed by use of a microprocessor to permit control of on-off timing and prevent undesirable effects of “sloshing.Type: GrantFiled: September 3, 2014Date of Patent: September 13, 2016Assignee: Touchsensor Technologies, LLCInventors: Roger D.

Patent number: 8227940Abstract: A touch switch apparatus emulating a mechanical switch includes a field effect sensor and an electric field stimulator mechanically associated with the field effect sensor. A field generation signal applied to the field effect sensor causes an electric field to be generated thereabout. The electric field stimulator can be moved between first and second positions with respect to the field effect sensor. When moved into proximity with the field effect sensor, the electric field stimulator disturbs the electric field. A detection circuit coupled to the field effect sensor detects and responds to the disturbance to the electric field.Type: GrantFiled: February 14, 2011Date of Patent: July 24, 2012Assignee: TouchSensor Technologies, LLCInventors: David W.

Patent number: 7850339Abstract: A display includes a substrate having front and rear sides and defining one or more optical paths. A light source corresponding to each optical path is associated with the rear side of the substrate. Light propagates from the light source to the front side of the substrate through the corresponding optical path. Offsetting the light source from the centerline of the optical path improves light diffusion by promoting light reflection off the sides of the optical path. Multiple light sources of different colors can be associated with each optical path to provide for variable color output from each optical path at the front side of the substrate.Type: GrantFiled: February 12, 2007Date of Patent: December 14, 2010Assignee: Touchsensor Technologies, LLCInventors: Bahar N.
