  • Publication number: 20190287295
    Abstract: A method and system for providing access to and control of parameters within a scenegraph includes redefining components or nodes' semantic within a scenegraph. The set of components or nodes (depending on the scenegraph structure) are required to enable access from the Application User Interface to selected scenegraph information. In one embodiment, a user interface is generated for controlling the scenegraph parameters. In addition, constraints can be implemented that allow or disallow access to certain scenegraph parameters and restrict their range of values.

  • Patent number: 10229027
    Abstract: 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.

  • Publication number: 20180294720
    Abstract: 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.

  • Patent number: 10060884
    Abstract: 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.

  • Patent number: 9970883
    Abstract: 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.

  • Patent number: 9003043
    Abstract: 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.
