Patent number: 10802566Abstract: A two-part interface PHY configuration includes a low-voltage PHY portion configured for instantiation on an SoC device fabricated using a cutting-edge technology node, and a high-voltage PHY portion configured for instantiation on a power management device (PMD) fabricated using a high-voltage technology node. The low-voltage PHY portion includes interface control and low-voltage I/O circuitry configured to transfer outgoing 3.3V data signals to the high-voltage PHY portion at low voltage levels, and the high-voltage PHY portion includes a driver circuit that retransmits the low-voltage data signals onto a bus at the required 3.3V level. Incoming 3.3V data signals pass through an attenuator circuit before being processed using a receiver circuit provided on the low-voltage PHY portion. In USB applications, outgoing USB High Speed data signals are generated by a driver circuit provided on a low-voltage USB PHY portion.Type: GrantFiled: July 6, 2018Date of Patent: October 13, 2020Assignee: Synopsys, Inc.Inventors: Andrew Chung Chun Lam, Davit Petrosyan, Dino A.

Patent number: 10272713Abstract: This device is composed of two pins. Each pin is made of plastic and a piece of magnetic that has opposite magnetic polarity facing each other. The pin can be used as a single unit where it can hold stationery such as papers, envelopes or small pamphlet to a ferromagnetic surface such as metal office cabinet, metal chalk board, refrigerator door or anywhere ferromagnetic surface exist. When used as one single unit the paper or stationery have some degree of rotational freedom and will self-center itself with the heaviest side down. It can also be attached to a center of a personal business card or credit card and be spun like a top vertically, horizontally or upside down on a ferromagnetic surface. However, when used as two individual pin to attach the stationery to a ferromagnetic surface such as metal office cabinet, metal chalk board, refrigerator door or anywhere ferromagnetic surface exist the stationeries will have no degree of rotational freedom and it will be fixed into position.Type: GrantFiled: January 11, 2017Date of Patent: April 30, 2019Inventor: Wai Chun Lam

Publication number: 20180140354Abstract: A device is designed to remove blockages in a lumen such as a thrombus, blood clot, or embolus. The device comprises a manipulating wire and a structure that can conduct electrical current to a lumen blockage. The electrical current is preferably in radio frequency (RF). The RF electric current in the blockage can excite the contents such as proteins of the blockage, so that cross-linking density and interfacial adsorption of the entire blockage is enhanced. The enhanced cross-linking density can result in increased fracture resistance of the blockage such that fracture of the blockage during the removal process is unlikely. The enhanced interfacial adsorption results in increased interfacial fracture resistance between the device and blockage so that the blockage can be securely captured during the removal process without using radially applied force.Type: ApplicationFiled: June 6, 2016Publication date: May 24, 2018Inventors: David Chuen Chun Lam, Chi Hang Chon, John Ching Kwong Kwok, Matthew Ming Fai Yuen, Zhen Qin, Alexander Ka Ngai Lam

Publication number: 20150289892Abstract: The claimed biocompatible device is designed to remove vessel occlusions such as a thrombus, blood clot, or embolus. The claimed devices maybe used to treat occlusions in the brain, in the vasculature, and in tissues and organs. The device is in a form of a wire or wire-like structure which can capture the occlusion with minimal contact force with the vessel wall by an application of electricity, or electrical, chemical, or microwave generated heat to enable capture of the occlusion by the device. The device, compared to conventional mechanical thrombectomy devices, captures the occlusion and reduces occlusion fragmentation without large radial force and vessel wall friction that can damage the vessel wall.Type: ApplicationFiled: November 20, 2013Publication date: October 15, 2015Inventors: David Chuen Chun Lam, Chi Hang Chon, John Ching Kwong Kwok, Matthew Ming Fai Yuen, Zhen Qin, Alexander Ka Ngai Lam, Ka Kit Leung, Wai Lun Ko
