Abstract: Position-based sensing methods and systems can be used to transmit data from an input device to a touch-sensitive device. For example, the touch sensing system may perform one or more coarse input device sub-scans to determine a coarse location of the input device. The coarse location can be used to select one or more touch sensors (or sensor channels) to sample for decoding data encoded in the stimulation signals from the input device. During one or more fine input device sub-scans, the touch sensing system can determine a fine location of the input device and decode the data from the input device sampled from the selected touch sensors (or sensor channels).

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 receive at its input a combination of stylus receive channels that are combined in a manner to minimize noise while at the same time keeping the stylus signal strength uniform independent of the position of the stylus on the device.

Abstract: A touch sensitive device can be capable of detecting signals generated by a stylus and correcting the detected stylus signals for effects due to noise present on the device. In one example, signals are taken from one or more electrodes that are a pre-determined distance away from an electrode in which a stylus signal is detected. The pre-determined distance can be empirically determined such that a noise estimate can be generated such that the electrodes have a higher probability of containing only noise that is highly correlated to the noise present on a detected stylus signal. The generated noise estimate is then subtracted from a detected stylus signal to reduce the effect of noise on the stylus signal.

Abstract: Time synchronization between a central wireless communication device and a peripheral wireless communication device is described. Events associated with an application are time stamped at the central wireless communication device, and one or more link layer messages are sent to the peripheral wireless communication device to provide time stamp information to replicate the event timing at the peripheral wireless communication device. A first link layer message includes information about an internal Bluetooth clock to calibrate a corresponding internal clock value at the peripheral wireless communication device. A second link layer message includes information about a current value for the Bluetooth clock and also a value for an offset that provides a time position at a finer granularity than the Bluetooth clock within a timeslot specified by the Bluetooth clock value. Application layer event synchronization between the central and peripheral wireless communication devices allow for power reduced dormant states between events.

Abstract: Various embodiments include a light source module with one or more light emitters and one or more light sensors that share an aperture via which light passes. One of the light sensors may measure illuminance received through the aperture (not illuminance from the light emitters) and send a signal indicating a measurement of the illuminance. The light source module may be integrated into a portable computing device having a controller. The controller may include logic to perform one or more device operations based on the measurement of illuminance, such as, but not limited to, controlling a device display brightness and/or controlling an auto exposure feature of the device camera. Calibration parameters for interpreting the signal may be determined via a calibration process.

Abstract: A touch controller that can configure touch circuitry according to a scan plan, which can define a sequence of scan events to be performed on a touch panel is disclosed. The touch controller can include a configurable transmit section to generate stimulation signals to drive the panel, a configurable receive section to receive and process touch signals from the panel, and a configurable memory to store the touch signals. The touch controller can also include a programmable scan engine to configure the transmit section, the receive section, and the memory according to the scan plan. The touch controller advantageously provides more robust and flexible touch circuitry to handle various types of touch events at the panel. An active stylus that can generate stimulation signals that can be detected by the touch controller during various touch events at the panel is also disclosed.

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: Power consumption of touch sensing operations for touch sensitive devices can be reduced by implementing a coarse scan (e.g., banked common mode scan) to coarsely detect the presence or absence of an object touching or proximate to a touch sensor panel and the results of the coarse scan can be used to dynamically adjust the operation of the touch sensitive device to perform or not perform a fine scan (e.g., targeted active mode scan). In some examples, the results of the coarse scan can be used to program a touch controller for the next touch sensing frame to idle when no touch event is detected or to perform a fine scan when one or more touch events are detected. In some examples, the results of the coarse scan can be used to abort a scheduled fine scan during the current touch sensing frame when no touch event is detected.

Abstract: Systems for detecting an amount and/or location of a force applied to a device using a piezoelectric film are provided. One example system can include a transparent piezoelectric film for generating an electric charge in response to a deformation of the film. Electrodes positioned on opposite surfaces of the piezoelectric film can be used to detect the generated electric charge and determine an amount and/or location of force applied to the film based on the generated electric charge. In another embodiment, the system can include a capacitive touch sensor for determining a location of a touch event on the device.
