Abstract: A camera system may include circuitry for measuring the positions of an optics assembly (e.g., one or more lenses) and/or an image sensor of the camera system. The circuitry may include analog circuits comprising a first and a second position sensors to produce a first and a second sensor signals based on a first magnetic field and a second magnetic field respectively. The magnetic fields may have the same or different polarities detectable by the position sensors. The position sensors may be coupled in parallel in the same or reverse directions to produce a combined sensor output. The circuitry may determine position information for the optics assembly and/or the image sensor based on the combined sensor output. The camera system may use the position information as a feedback signal to control the position of the optics assembly (e.g., for autofocus) and/or the position of the image sensor (e.g., for optical image stabilization (OIS)).

Abstract: This relates to a monitoring system capable of measuring a plurality of vital signs. The monitoring system can include a plurality of sensors including, but not limited to, electrodes, piezoelectric sensors, temperature sensors, and accelerometers. The monitoring system can be capable of operating in one or more operation modes such as, for example: capacitance measurement mode, electrical measurement mode, piezoelectric measurement mode, temperature measurement mode, acceleration measurement mode, impedance measurement mode, and standby mode. Based on the measured values, the monitoring system can analyze the user's sleep, provide feedback and suggestions to the user, and/or can adjust or control the environmental conditions to improve the user's sleep. The monitoring system can further be capable of analyzing the sleep of the user(s) without directly contacting or attaching uncomfortable probes to the user(s) and without having to analyze the sleep in an unknown environment (e.g., a medical facility).

Abstract: In one aspect, the present disclosure relates to a method including determining which sense lines are potentially corrupted based on touch image information, measuring a sense signal on each sense line, and applying a trained best compensation factor to the measured sense signal on potentially corrupted sense lines in order to produce a corrected sense signal. The corrected sense signal eliminates active stylus signal that has cross-coupled to a touch contact (e.g., a finger or conductive stylus) and thereby mitigates errors in stylus location due to cross-coupled signal.

Abstract: A touch sensing system can demodulate sensor data using a dynamically adjusted demodulation waveform and/or demodulation window. The demodulation waveform and/or demodulation window can be dynamically adjusted to account for dynamically changing noise in a touch sensing system. The system can dynamically adjust the demodulation window based on noise measured by the touch sensing system to generate an optimized or otherwise noise-tailored window to suppress detected noise. In some examples, the noise measured by the touch sensing system can be sampled from sense channels localized to a detected touch.

Abstract: A touch controller on a touch sensitive device configured to generate a dynamic demodulation waveform so as to minimize the effects on a signal to noise ratio caused by a tonal noise is disclosed. The demodulation waveform can be turned off for finite durations so as to minimize the probability that a transitional voltage of the tonal noise source is included in the demodulation result.

Abstract: Noise in sensor panel measurements can be reduced using a common pixel correction algorithm. Noise can be introduced into touch or force sensor panel measurements, for example, by circuitry of a transmit (Tx) section or a receive (Rx) section coupled to one or more sensing nodes of a sensor panel. For example, a digital-to-analog converter in the transmit section or an analog-to-digital converter in the receive section can introduce low-frequency correlated noise. Additionally, transmit and receive sections can introduce uncorrelated noise into the system. Reference nodes, coupled between Tx and Rx sections, can sense correlated and uncorrelated noise from the Tx and Rx sections. The noise measured at reference nodes can be subtract from signals measured at other sensing nodes coupled to the same Rx channel. The measurement at the reference node can be scaled using a scaling parameter to account for differences between reference nodes and sensing nodes.

Abstract: A touch input device configured to detect stylus signals generated by an external stylus is provided. The touch input device includes a plurality of stylus signal detectors that can receive the stylus signal and estimate the start and end time of the stylus signal in order to facilitate windowed demodulation of signal. The start and end times are then used to facilitate a windowed demodulation of the stylus signal.
