Patent number: 11460973Abstract: Node-link data can be converted into audio outputs. For example, a system can generate a graphical user interface (GUI) depicting a node-link diagram having nodes and links. The GUI can include a virtual reference point in the node-link diagram and a virtual control element that is rotatable around the virtual reference point by a user to contact one or more of the nodes in the node-link diagram. The system can receive user input for rotating the virtual control element around the virtual reference point, which can generate a contact between the virtual control element and a particular node of the node-link diagram. In response to detecting the contact, the system can determine a sound characteristic configured to indicate an attribute associated with the particular node. The system can then generate a sound having the sound characteristic, for example to assist the user in exploring the node-link diagram.Type: GrantFiled: April 11, 2022Date of Patent: October 4, 2022Assignee: SAS INSTITUTE INC:.Inventors: Sean Patrick Mealin, Claude Edward Summers, II, Mitchel Stanley Soltys, II, Ralph Johnson Marshall, Jr., Jesse Daniel Sookne, Brice Joseph Smith, Gregory David Kraus, Eric Colin Bolender, Julianna Elizabeth Langston, Lisa Beth Morton Robinson

Patent number: 10651734Abstract: A voltage regulator includes power stages and a controller. The power stages are configured to provide power to a load in response to a pulse-width modulated (PWM) signal and to provide a body braking to the load in response to a body braking signal. The body braking is provided via a body diode of the power stage. The controller is configured to provide the PWM signals to a first power stage and a second power stage based upon a power demand of the load, to provide body braking signals to the first power stage and the second power stage in response to an over-voltage condition on the load, and to suspend the first body braking signal to the first power stage and maintain the second body braking signal to the second power stage, in response to an over-temperature condition on the first power stage.Type: GrantFiled: April 11, 2017Date of Patent: May 12, 2020Assignee: Dell Products, L.P.Inventors: Guangyong Zhu, Mehran Mirjafari, Ralph Johnson

Patent number: 10229027Abstract: A voltage regulator power reporting offset system includes a monitored power reporting subsystem that determines a monitored power level, offsets the monitored power level using voltage regulator operation offset information to provide a first offset monitored power level, and reports the first offset monitored power level to voltage regulator operation components. A processor power reporting component receives the report of the first offset monitored power level from the monitored power reporting subsystem. A processor power reporting offset subsystem receives the report of the first offset monitored power level from the processor power reporting component, offsets the first offset monitored power level using the processor operation offset information to provide a second offset monitored power level that is different than the first offset monitored power level, and reports the second offset monitored power level to a processing system.Type: GrantFiled: April 15, 2016Date of Patent: March 12, 2019Assignee: Dell Products L.P.Inventors: Shiguo Luo, Ralph Johnson

Patent number: 10060884Abstract: A method of scanning a sample includes simultaneously forming a plurality of co-linear scans. Each scan is formed by a sweep of a spot by an acousto-optical device (AOD). The co-linear scans are separated by a predetermined spacing. A first plurality of swaths are formed by repeating the simultaneous forming of the plurality of co-linear scans in a direction perpendicular to the co-linear scans. The first plurality of swaths have an inter-swath spacing that is the same as the predetermined spacing. The predetermined spacing can be a scan length or an integral number of scan lengths. A second plurality of swaths can be formed adjacent to the first plurality of swaths. Forming the second plurality of swaths can be performed in an opposite direction to that of the first plurality of swaths or in a same direction. An inspection system can implement this method by including a diffractive optical element (DOE) path after a magnification changer.Type: GrantFiled: June 16, 2016Date of Patent: August 28, 2018Assignee: KLA-Tencor CorporationInventors: Jamie Sullivan, Wenjian Cai, Yevgeniy Churin, Ralph Johnson, Meier Yitzhak Brender, Mark Shi Wang, Rex Runyon, Kai Cao

Patent number: 9970883Abstract: Disclosed are apparatus and methods for inspecting or measuring a specimen. A system comprises an illumination channel for generating and deflecting a plurality of incident beams to form a plurality of spots that scan across a segmented line comprised of a plurality of scan portions of the specimen. The system also includes one or more detection channels for sensing light emanating from a specimen in response to the incident beams directed towards such specimen and collecting a detected image for each scan portion as each incident beam's spot is scanned over its scan portion. The one or more detection channels include at least one longitudinal side channel for longitudinally collecting a detected image for each scan portion as each incident beam's spot is scanned over its scan portion.Type: GrantFiled: January 5, 2017Date of Patent: May 15, 2018Assignee: KLA-Tencor CorporationInventors: Jamie M.

Patent number: 9003043Abstract: Described are techniques for facilitating communications between a client and a server. A first communication connection is opened between the client and server and remains open for a duration of a session. In response to receiving a client request, a second communication connection is opened. The client request is sent over the second communication connection to the server. A first response is sent to said client over the second communication connection. The second communication connection is closed. The client request is serviced and a data portion indicating a status is sent to the client over the first communication connection. The data portion is included in a second response sent from the server to the client over the first communication connection. If there are other client requests received by the server and processed during the session, additional data portions for the other client requests are included in the second response.Type: GrantFiled: December 17, 2008Date of Patent: April 7, 2015Assignee: EMC CorporationInventors: Vicente Moranta, Mark A.

Patent number: 8827847Abstract: A training aid (10) provides real-time biometric feedback for swung or linearly accelerated implements where the feedback is provided above a user adjustable threshold. The training aid (10) includes a two-part housing (12) and mounting means for releasably mounting the housing to an implement. A battery (16) is located in the housing (12) with a buzzer (22) connected to the battery (16) through an electrical circuit. A force activated switch (14) in the electrical circuit is activated to energize the buzzer (22) to sound in response to displacement of the training aid. The force activated switch (14) has a force threshold at which the force activated switch (14) is activated to energize the buzzer (22) to sound. The force activated switch (14) is configured so that the force threshold is user adjustable.Type: GrantFiled: June 16, 2010Date of Patent: September 9, 2014Inventor: Vernon Ralph Johnson
