摘要： A method of measuring resistance in each of a plurality of resistors in a resistor matrix is provided. Each resistor is located at a different intersection between a column conductor and a row conductor. The method includes determining an offset error row current of each row conductor, scanning each row conductor to identify if that row conductor is connected to a column conductor by one of the plurality of resistors, scanning each resistor connected to that row conductor to determine if that resistor is connecting a column conductor to that row conductor, and if that resistor is connecting a column conductor to that row conductor, outputting an offset compensated resistance of that resistor calculated from the row current measured for that resistor less the offset error row current for that row conductor.

摘要： A remote multi-touch system includes a pressure-sensitive, multi-touch device, a display separate from the pressure-sensitive, multi-touch device, and a controller communicatively coupled to the pressure-sensitive, multi-touch device and the display. The pressure-sensitive, multi-touch device measures a position at which one or more touches are executed on the pressure-sensitive, multi-touch device and, for each of the one or more touches, a force with which that touch is executed. The controller receives a touch report for each of the one or more touches from the pressure-sensitive, multi-touch device. Each touch report indicates the position at which that touch is executed and the force with which that touch is executed. The controller outputs to the display a pre-touch visualization command for displaying a pre-touch visualization. The pre-touch visualization is displayed at a location of the display mapped from the position at which that touch is executed on the pressure-sensitive, multi-touch device.

摘要： An interactive display system includes a pixel-based display surface and a light pen. A sequence of patterns is projected onto the display surface. The sequence of patterns has a unique sequence of light intensities for each location of the display surface. Intensities of light at an arbitrary location are sensed by the light pen while projecting the sequence of patterns. The intensifies of light are decoded to determine coordinates of the arbitrary location.

摘要： A relative fullness of a fluid container is monitored by directing reference light at a bottom surface of the fluid container. The fluid container is designed so that the amount or pattern of reference light reflected from the fluid container varies in relation to the relative fullness of the fluid container. Accordingly, the relative amount or pattern of reference light reflected from the fluid container can be monitored and used to determine the relative fullness of the fluid container.

摘要： Certain electrical systems, such as projectors, contain components, which get very hot and require active cooling systems. During normal operation, a switch operates a cooling fan from a primary power supply. Upon detecting a failure in the primary power supply, the switch connects the cooling fan to a secondary power supply.

摘要： A resistive matrix with optimized input scanning is provided by a method of discerning input location(s) on a resistive column-row matrix which includes receiving physically-applied input(s) at the resistive column-row matrix and, during application of the one or more physically-applied inputs, performing a hierarchical scan of the resistive column-row matrix to determine whether the physically-applied input(s) are causing activation of a column-row cell within a multi-cell group of the resistive column-row matrix. The method further includes performing a supplemental scan within a multi-cell group if it is determined that a physically-applied input is causing activation of a column-row cell within the multi-cell group, and generating, based on the hierarchical and supplemental scans, an output indicative of the input location(s) on the resistive column-row matrix of the one or more physically-applied inputs.
