Patent number: 10402322Abstract: Methods for read after write forwarding using a virtual address are disclosed. A method includes determining when a virtual address has been remapped from corresponding to a first physical address to a second physical address and determining if all stores occupying a store queue before the remapping have been retired from the store queue. Loads that are younger than the stores that occupied the store queue before the remapping are prevented from being dispatched and executed until the stores that occupied the store queue before the remapping have left the store queue and become globally visible.Type: GrantFiled: August 25, 2017Date of Patent: September 3, 2019Assignee: Intel CorporationInventors: Karthikeyan Avudaiyappan, Paul Chan

Patent number: 8805049Abstract: Methods, systems, and related computer program products for computer-aided detection (CAD) of anatomical abnormalities in digital (or digitized) x-ray mammograms are described. The inventive techniques are based on using a foundational CAD processing algorithm that is characterized by at least one of non-shift-invariance, non-rotational-invariance, and non-inversional-invariance. According to one preferred embodiment, a first x-ray mammogram image of a breast is received, and at least one altered version thereof is generated that differs therefrom by at least one of image shift, image rotation, and image inversion. The first x-ray mammogram image and each of the at least one altered versions thereof are individually processed using the foundational CAD algorithm to generate a respective plurality of individual CAD detection sets. The plurality of CAD detection sets are then compared to generate an overall CAD detection set.Type: GrantFiled: April 19, 2012Date of Patent: August 12, 2014Assignee: Hologic, Inc.Inventors: Paul Chan, Keith W.

Patent number: 7999357Abstract: The present invention advantageously provides a circular-arc shaped structure for forward biased steering diodes used in an ESD circuit, which circular arc shaped structure forward biases steering diodes effectively prevent concentration of an ESD pulse to one section of the p-n junction within the forward biased steering diode (or, alternatively viewed, evenly distributing stress along the entire p-n junction), thus increasing reliability of the ESD circuit, and also minimizing input capacitance as well as occupying a smaller area. The circular-arc shaped structure thus provides a mechanism to evenly distribute the current flow through the ESD steering diodes, and therefore avoids the disadvantage of a voltage gradient along the steering diode structure.Type: GrantFiled: May 12, 2009Date of Patent: August 16, 2011Assignee: Semiconductor Components Industries, LLCInventor: Paul Chan

Publication number: 20050131757Abstract: A method and system for permission-based communication and exchange of information by means of a neutral and unified database in which consumers remain anonymous. The method involves receiving and storing consumer information corresponding to a number of individual consumers via a consumer information receiver, the consumer information including both consumer-identifying information and consumer profile information for each consumer. The method also involves receiving a profile information search request which specifies at least one consumer profile criterion. The method also involves searching the consumer database to identify selected records which match the consumer profile criterion in order to obtain a search result. The method also involves providing the search result to the requestor via a search result provider, and wherein the search result does not include any consumer-identifying information.Type: ApplicationFiled: February 19, 2003Publication date: June 16, 2005Applicant: Pureprofile.

Publication number: 20050024962Abstract: A symmetric dual-voltage charge pump and its control circuit generate bipolar output voltages. The charge pump converts a unipolar power source to a set of dual-voltage outputs of opposite polarity that are completely independent of each other. The charge pump includes two voltage-boosting transfer capacitors and two output capacitors. Two-phase operation generates an increased-magnitude output voltage of a negative polarity and another two phases of operation generate an increased output voltage of a positive polarity. The charge pump selectively charges one or both of the bipolar outputs with individual 2-phase charge cycles or with a sequence of charge cycles. When controlled by comparators with unequal reference voltages, the charge pump can force the bipolar outputs to unequal positive and negative voltages. Charge pumping is faster since only 2 phases are needed for charging either the positive or negative output.Type: ApplicationFiled: June 16, 2004Publication date: February 3, 2005Applicant: PERICOM TECHNOLOGY (SHANGHAI) CO. LTD.Inventors: Paul Chan, Zhen Luo, Shun Wu, Jian Pan

Patent number: 6627435Abstract: A perfusion incubator having a fluid conditioning unit (12), a well assembly (7) and a well assembly heating unit (14), a peristaltic pump (4) and a fluid collection unit (11). The well assembly has a number of wells (20, 21) each having a transparent lid (30) and a fluid inlet (26) and a fluid outlet (27). An illumination device (13) is under the well so that the cell being cultured in the well assembly can be observed by means of a microscope (15). Each fluid inlet (26) is positioned so as to allow a tangential entry of fluid to the well at a mid point in the well, and each fluid outlet (27) is above the fluid inlet with the cell to be cultured in a lower portion of the well so that flow of fluid in the well is formed into a vortex which tends to draw fluid from around the cell without direct flow over the embryo.Type: GrantFiled: March 28, 2001Date of Patent: September 30, 2003Assignees: William A.
