Abstract: A sensor system combining first and second detection systems supplies drive signals to nodes A and B electrodes of these systems. A drive sequence consists of a repetition of an elementary acquisition cycle having two consecutive main phases with pre-charge and acquisition phases. During a first pre-charge phase, node A is driven to a first electrical potential for and during a first acquisition phase, to a first intermediate electrical potential, and node B is driven to a second electrical potential and thereafter switches node B into high-impedance at DC, and during a second pre-charge phase, node A is driven to a third electrical potential and, during a second acquisition phase, to a second intermediate electrical potential, and node B is driven to a fourth potential and thereafter switches node B into high-impedance at DC. The first and second detection systems perform an electrical measurement on node A and B, respectively.

Abstract: A system has a two-dimensional (2D) touch detection system operable to be activated and de-activated and an additional sensor operable in communication with the 2D touch detection system. The additional sensor is capable to determine whether a touch event has occurred or is about to occur and to activate the 2D touch detection system if a touch event has occurred or is about to occur.

Abstract: Systems and methods of determining a noise-robust acquisition configuration for a sensor or communication system are disclosed. An exemplary method comprises a noise scan with: obtaining a sensor receive signal from the sensor system; determining a digital receive signal from the sensor receive signal by A/D conversion of the sensor receive signal at a predefined noise scan frequency; determining a plurality of decimated digital receive signals by integer decimation of the digital receive signal using two or more decimation rates that differ from each other, wherein each of the two or more decimation rates is associated with a respective candidate acquisition configuration; determining one or more noise measures for multiple of the candidate acquisition configurations using one or more of the plurality of decimated digital receive signals; and using the one or more noise measures, determining the acquisition configuration for operation of the sensor system from the candidate acquisition configurations.

Abstract: A position tracking system may include a processor and a memory coupled to the processor. The memory may include instructions that, when loaded and executed by the processor, cause the processor to receive a plurality of measurements from a sensor and map a location of an object to a measurement using movement models. The mapping may be based upon a cost computed from movement models, the measurement, and the location.

Abstract: A method for state tracking based gesture recognition engine for a sensor system has the steps of: defining a plurality of sequential states of a finite-state machine, determining a Sequence Progress Level (SPL) for each state, mapping a state probability distribution to a (single) SPL on run-time, and utilizing the mapped SPL estimate as an output value of the sensor system.
