Title: Method and apparatus for sensing and for improving sensor accuracy
Inventor: MANUEL PINUELA RANGEL
IPC: G08B29/20
Filed: 2016-06-27
Abstract: Method for sensing an environmental parameter such as levels of carbon dioxide, carbon monoxide, ozone and other contaminants which even at lower than normally hazardous levels may still be dangerous to human health if exposure occurs for longer periods. In particular the invention relates to controlling a sensor system by obtaining from each of a plurality of sensors, first sensor data indicative of a level of an environmental contaminant at each of the plurality of sensors and determining first calibration data based on the first sensor data. Then obtaining from a selected sensor over a wide area communications network a plurality of items of second sensor data each indicative of the level of the environmental contaminant sensed by the selected sensor. A calibration for the selected sensor is determined based on the second sensor data and the first calibration data. An indication of the level of the contaminant at the selected sensor is provided, wherein the indication is corrected using the calibration data. The method is able to provide an indication of the level of a contaminant at a geographical location of the selected sensor.

Title: Electronic device for pressure sensors
Inventor: JAMES HARDING
IPC: H01L27/12
Filed: 2017-10-27
Abstract: A device has a stack of layers defining an array of transistors. The stack includes a surface conductor pattern defining i) an array of gate conductors 6, each providing gate electrodes for a column of transistors and ii) an array of pixel conductors 8 for each transistor. Each pixel conductor 8 is connected by a semiconductor channel 14 to an array of conductors 16 running along rows of transistors. The gate conductor 6 of each transistor column extends around the pixel conductors 8 in that column. A pressure sensor may be formed by positioning a film of material, having pressure-dependent conductivity, in electrical contact with the surface conductor pattern. Patterning the film is not required, since the surface conductor pattern minimises cross talk between gate lines 6, reducing the impact of changes in the resistance of the pressure sensitive film on the read lines of adjacent columns and rows.
