Patent number: 10462686Abstract: A testing system tests a device under test (DUT) by emulating at least one radio access protocol. The testing system includes at least one transmitter, multiple receivers, multiple radio frequency (RF) heads, multiple horns, and multiple combiners. The transmitter(s) are configured to use an intermediate frequency for transmission. The receiver(s) are configured to use an intermediate frequency for reception. The RF heads up-convert the intermediate frequency from the transmitter(s) to RF used by the DUT and down-convert the RF used by the DUT to the intermediate frequency used by the receiver(s). The combiners each correspond to a different receiver and combine beamformed signals received from the DUT via two different RF heads and via the horns. The horns transmit RF signals to the DUT and receive RF signals from the DUT using two different polarizations.Type: GrantFiled: October 23, 2017Date of Patent: October 29, 2019Assignee: Keysight Technologies, Inc.Inventors: Francisco Javier Campos García, Binu Mathew

Patent number: 10019971Abstract: The disclosed embodiments provide a system that facilitates driving a display in a computer system. During operation, the system receives an input video stream from a graphics source, wherein the input video stream comprises a sequence of video frames. Next, the system directs the input video stream through a set of two or more memory buffers including a front buffer and a back buffer to produce an output video stream, which is used to drive the display. While directing the input video stream through the set of memory buffers, the system writes a video frame from the input video stream into the back buffer, and concurrently drives the output video stream from a preceding video frame in the front buffer. When the writing of the video frame completes, the system switches buffers so that the back buffer becomes the front buffer, which drives the output video stream, and the front buffer becomes either a spare buffer or the back buffer, which receives a subsequent frame from the input video stream.Type: GrantFiled: May 13, 2014Date of Patent: July 10, 2018Assignee: Apple Inc.Inventors: Binu Mathew, William C. Athas, Nils E. Mattisson

Patent number: 9560667Abstract: A transceiver adapted to emulate devices using one or more of a plurality of different radio access protocols. The transceiver comprises a timing module, the timing module being adapted to maintain a record of the current timing state which would apply to each of the different radio access protocols the transceiver is able to use, if that radio access protocol was being used. When the transceiver changes a radio access protocol being used to emulate a device from a first radio access protocol used to emulate a first device to a second radio access protocol used to emulate a second device, the transceiver is adapted to use the record of the current timing state which would apply to the second radio access protocol to set the timing of the second radio access protocol.Type: GrantFiled: December 11, 2013Date of Patent: January 31, 2017Assignee: Keysight Technologies Singapore (Holdings) Pte.
