  • Patent number: 12248644
    Abstract: A circuit arrangement for a touch sensor includes a plurality of capacitive sensors, an ADC, a switch arrangement, and a controller. The capacitive sensors measure over a respective sampling period for detecting a touch event on a surface and provide an output. The ADC receives the output and determines a digital value over a conversion period. The switch arrangement selectively provides the output from the capacitive sensors to the ADC. The controller activates a first capacitive sensor to measure the capacitance for detecting a touch event, and activates a second capacitive sensor for detecting a touch event such that the respective sampling periods are at least partly concurrent. The controller also controls the switch arrangement to cause the ADC to receive the output of the first capacitive sensor after its sampling time and receive the output of the second capacitive sensor after its sampling time.

  • Patent number: 10839091
    Abstract: Machine logic (for example, software) for protecting sensitive and confidential user data and sending the protected user data to an authorized third party for predictive analytics purposes. The machine logic rules perform linear transformation operations on the sensitive and confidential user data in order to obscure the underlying data before it is sent to an authorized third party for performing predictive analysis of the underlying data. After performing predictive analysis on the obscured data by the authorized third party, the owner of the sensitive and confidential data takes a consequential action (that is, the owner of the data makes a business-related decision) based on the prediction.
