Patent number: 10042476Abstract: A channel scan architecture for detecting touch events on a touch sensor panel is disclosed. The channel scan architecture can combine drive logic, sense channels and channel scan logic on a single monolithic chip. The channel scan logic can be configured to implement a sequence of scanning processes in a panel subsystem without intervention from a panel processor. The channel scan architecture can provide scan sequence control to enable the panel processor to control the sequence in which individual scans are implemented in the panel subsystem. Type of scans that can be implemented in the panel subsystem can include a spectral analysis scan, touch scan, phantom touch scan, ambient light level scan, proximity scan and temperature scan.Type: GrantFiled: May 18, 2016Date of Patent: August 7, 2018Assignee: Apple Inc.Inventors: Thomas James Wilson, Christoph H. Krah, Minh-Dieu Thi Vu

Patent number: 10031609Abstract: A device that can autonomously scan a sensor panel is disclosed. Autonomous scanning can be performed by implementing channel scan logic. In one embodiment, channel scan logic carries out many of the functions that a processor would normally undertake, including generating timing sequences and obtaining result data; comparing scan result data against a threshold value (e.g., in an auto-scan mode); generating row count; selecting one or more scanning frequency bands; power management control; and performing an auto-scan routine in a low power mode.Type: GrantFiled: June 3, 2015Date of Patent: July 24, 2018Assignee: Apple Inc.Inventors: Minh-Dieu Thi Vu, Thomas James Wilson, Christoph H.

Patent number: 9965100Abstract: A sensor panel device that can generate and use a stimulus signal having multiple different waveforms for detecting events on or near the sensor panel is disclosed. Among other things, such a stimulus signal can be used to reject environmental noise present in the device. In some embodiments, the stimulus signal has multiple waveforms having different frequencies. Logic circuitry can generate representative values from output of the different waveforms applied to one or more sensing nodes in the sensor panel device. From the representative values, a final value can be generated that represents whether an event occurred at or near the one or more sensing nodes.Type: GrantFiled: February 27, 2017Date of Patent: May 8, 2018Assignee: Apple Inc.Inventors: Christoph Horst Krah, Minh-Dieu Thi Vu

Publication number: 20180070473Abstract: A modular fan chassis air filtering system includes a base that defines a fan device housing that houses a fan device. At least one system chassis coupling feature is included on the base and couples to a system chassis via a modular fan chassis housing defined by the system chassis. An air inlet is defined by the base and allows air to enter the fan device housing in response to operation of the fan device. An air outlet is defined by the base and allows air to exit the fan device housing in response to operation of the fan device. An air filter housing is defined by the base, located between the air inlet and the air outlet, and houses an air filter that filters the air that enters the fan device housing through the air inlet before that air exits the fan device housing through the air outlet.Type: ApplicationFiled: September 7, 2016Publication date: March 8, 2018Inventors: Joanne Cuijuan Zhang, Thuy Thanh Thi Vu

Patent number: 9528665Abstract: A method for fabricating light-emitting devices includes obtaining a plurality of light-emitting diode (LED) chips fabricated to emit blue light and preparing a phosphor-containing material comprising a matrix material having dispersed therein a mixture of a red phosphor and a green phosphor in a fixed ratio to each other. The method also includes disposing different thicknesses of the phosphor-containing material on different ones of the LED chips. The fixed ratio is chosen such that LED chips having different thicknesses of the phosphor-containing material emit light characterized by different points along the Planckian locus in a CIE chromaticity diagram.Type: GrantFiled: March 15, 2013Date of Patent: December 27, 2016Assignee: LedEngin, Inc.Inventors: Zequn Mei, Truc Phoung Thi Vu

Publication number: 20160283038Abstract: A system and method for autonomously scanning a sensor panel device is disclosed. A sensor panel processor can be disabled after a first predetermined amount of time has elapsed without the sensor panel device sensing any events. One or more system clocks can also be disabled to conserve power. While the processor and one or more system clocks are disabled, the sensor panel device can periodically autonomously scan the sensor panel for touch activity. If one or more results from the autonomous scans exceed a threshold, the sensor panel device re-enables the processor and one or more clocks to actively scan the sensor panel. If the threshold is not exceeded, the sensor panel device continues to periodically autonomously scan the sensor panel without intervention from the processor. The sensor panel device can periodically perform calibration functions to account for any drift that may be present in the system.Type: ApplicationFiled: June 7, 2016Publication date: September 29, 2016Inventors: Christoph H. KRAH, Minh-Dieu Thi VU, Thomas James WILSON

Patent number: 9274613Abstract: As keys of the keyboard of a portable communication device are asserted, the device dynamically determines at least a portion of a corresponding telephone number to present on the device's display by, at least in part, considering likelihoods of differing explicit and implicit interpretations of these key assertions. By one approach this can comprise according a likelihood advantage to an explicit interpretation of one or more of the key assertions and/or implicit interpretations of such key assertions. These likelihood advantages need not be necessarily dispositive with respect to the resultant interpretation.Type: GrantFiled: June 13, 2014Date of Patent: March 1, 2016Assignee: BlackBerry LimitedInventors: David Brandon Sosby, My Phuong Thi Vu, Satyam Babu Kothapally
