G06F 3/033

US Classification:

345174, 345179, 178 1806, 178 1903

Abstract:

A system comprising a sensing device and a capacitive sense array configured to track the position of a stylus and synchronize the capacitive sense array to the stylus transmit signal. The system is configured to track the position of both a stylus and a passive touch object. The system is further configured to track the position of the stylus using self capacitance sensing and track the position of the passive touch object using mutual capacitance sensing. The system further configured to modulate the stylus transmit signal to include additional data to support additional stylus functions.

G06F 3/033

US Classification:

345174, 345179

Abstract:

A system comprising a sensing device and a capacitive sense array configured to detect a presence of a passive touch object and a stylus where the capacitive sense array receives a transmit signal from the stylus via capacitive coupling. The system further comprising a processing device configured to determine the stylus location on the capacitive sense array based on the transmit signal and to synchronize the stylus to the capacitive sense array.A system further comprises a demodulation block to extract additional data that is modulated into the transmit signal by the stylus. The demodulation block is configured to extract the additional data by amplitude shift keying. The additional data comprises at least one of an applied force value of the stylus tip, a button status data, a battery status data, or a stylus acceleration data.

International Classification:

G06F 3/045
G01R 29/26

US Classification:

345174, 324613

Abstract:

A capacitance sensing system can filter noise that presents in a subset of electrodes in the proximity of a sense object (i.e., finger). A capacitance sensing system can include a sense network comprising a plurality of electrodes for generating sense values; a noise listening circuit configured to detect noise on a plurality of the electrodes; and a filtering circuit that enables a filtering for localized noise events when detected noise values are above one level, and disables the filtering for localized noise events when detected noise values are below the one level.

Cypress Semiconductor Corporation - San Jose CA

International Classification:

H02P 5/00

US Classification:

318 34, 318 66, 318 69

Abstract:

A system, fan controller and method for enhanced alert notification. Embodiments provide an effective mechanism for utilizing system fans to create alert tones or messages, where fan speed differentials may be adjusted to alter the frequency of the fan interference sounds. As such, existing hardware can be used to reduce cost by producing audible alerts which may be heard above ambient noise in a room with one or more electronic systems. Further, the frequency of the interference sounds may be altered to more clearly identify one or more systems to which a fault pertains.

Abstract:

Techniques for optical monitoring of corrosion are described herein. In an example embodiment, an optical monitor includes a target disposed within the optical monitor and exposed to ambient air, where exposure to the ambient air produces a change in an optical property of the target. The optical monitor also includes a light emitter to illuminate the target and an optical detector to generate a signal based on light reflected from the target. A processing device disposed within the optical monitor is configured to activate the light emitter and to receive and process the signal from the optical detector.
