  • Patent number: 7937188
    Abstract: Embodiments of the present invention are directed to systems and methods for controlling the temperature of an internal device while reducing or minimizing the involvement of the host. Thus, some of the heat monitoring and remediation work may be offloaded to the actual device itself. The device may monitor its own temperature and, in the event of high temperature, perform device specific heat reduction actions without involving the host. Furthermore, the device may, upon detecting temperature within a predefined range, alert the host of a high temperature condition in order to allow the host to perform temperature reduction measures. Also, the device may, upon detecting temperature within a predefined range, alert the host of an impending device shutdown and shut the device down. In addition, the device may periodically save its temperature into non-volatile memory in order to create a temperature log.

  • Patent number: 7901130
    Abstract: The presently described embodiments are directed to a calibration method and system for thin film thermistors that are locally heated with integrated thin film heaters. Initially, print head temperature is either measured or referenced. Then, transient thermistor resistances are measured and used to determine the thermistor resistance at a higher temperature. Notably, this calibration method is advantageously implemented as a step of an existing process without having to expose the print heads to operating temperatures. In some implementations of the presently described embodiments, trimming of the thermistors may be required once calibrated.

  • Patent number: 7718494
    Abstract: A method for forming a high-voltage drain metal-oxide-semiconductor (HVD-MOS) device includes providing a semiconductor substrate; forming a well region of a first conductivity type; and forming an embedded well region in the semiconductor substrate and only on a drain side of the HVD-MOS device, wherein the embedded region is of a second conductivity type opposite the first conductivity type. The step of forming the embedded well region includes simultaneously doping the embedded well region and a well region of a core regular MOS device, and simultaneously doping the embedded well region and a well region of an I/O regular MOS device, wherein the core and I/O regular MOS devices are of the first conductivity type. The method further includes forming a gate stack extending from over the embedded well region to over the well region.

  • Publication number: 20100064072
    Abstract: A network arbitration scheme is disclosed that manages device access fairness by selectively and dynamically increasing a requestor queue's likelihood of being serviced. A requestor queue increases its service priority by duplicating a request entry onto a set of priority rings maintained by arbitration hardware in a host bus adapter. Duplication occurs when (1) a requestor's queue fill count (the number of descriptors stored in the queue) exceeds a watermark level or (2) a requestor's queue timer times out. In the case of time-out, the requester in the lower priority ring will duplicate itself in the higher priority ring. Because the arbitration hardware services requesters using a round robin selection scheme, the likelihood of a requestor queue being serviced increases as the number of its duplicate request entries on a priority ring increases. Upon being serviced, the requester is able to perform the requested action.

  • Publication number: 20090313628
    Abstract: A client-server architecture provides mechanisms to assist in minimizing round trips between a client and server. The architecture exposes an object model for client use that is structured similarly to the server based object model. The client batches commands and then determines when to execute the batched commands on the server. Proxy objects act as proxies for objects and serve as a way to suggest additional data retrieval operations for objects which have not been retrieved. Conditional logic and exceptions may be handled on the server without requiring additional roundtrips between the client and server.
