Abstract: Mechanisms and techniques provide a data acquisition basic input output system between a central controller and a set of modules networked to the central controller. The central controller obtains at least one command to be sent to at least one module of the set of modules networked to the central controller and composing a request message containing the command. The request message has an associated timing pattern selected from a plurality of available timing patterns, such as a fixed timing pattern or a variable timing pattern. The central controller transmits the request message to the module(s) according to the associated timing pattern and receives, according to the associated timing pattern, a response message from the module(s). The data acquisition basic input output system communications do not require reliance on transport layer protocols or collision avoidance techniques.

Abstract: Mechanisms and techniques are provided which allow a server computer system, such as a web server, to generate information, such as a web page, which includes an audio resource locator (ARL) configured in accordance with the invention. The ARL includes a reference to audio data, an audio command, and an audio server reference that identifies an audio server computer system that can process the reference to audio data within the ARL according to the audio command within the ARL to producing output, which may be audio or another type of output. The server computer system can serve the information including the ARL to an originator of a request for such information, such as a browser on a client computer system. A client computer system configured with a browser can obtain the information containing the ARL and can reference the ARL which causes the client computer system to send a request to process audio data to the audio server specified in the ARL.

Abstract: The disclosed optical encoder includes a scale and a sensor head. The scale includes an optical grating and an optical element. The sensor head includes a light source, a detector array, and an index detector all of which are disposed on a substrate. The scale is disposed opposite the sensor head and is disposed for movement relative to the sensor head. The distance between the scale and the sensor head is selected so that the detector array lies near a talbot imaging plane. The light source emits a diverging beam of light, which is directed towards the scale. Light from the diverging beam of light is diffracted by the grating towards the detector array. Light from the diverging beam of light is diffracted by the optical element towards the index detector. The detector array provides a measurement of the position of the sensor head relative to the scale. The index detector provides a reference measurement of the position of the sensor head relative to the scale.

Abstract: Disclosed is a method, system, and program for providing data updates to a page, wherein the page includes multiple regions of dynamic content that may be separately updated independently of each other. The regions of the page are displayed within a presentation program executing on a client. A server transfers the page to the client over a network. The server detects state changes and queues information on the state changes. The server further generates an update package including content indicating the state changes and sends the update package to the client. The presentation program in the client renders the information on the state changes to the regions of the page including the dynamic content modified by the content indicating the state changes.

Abstract: Mechanisms and techniques provide a system for controlling performance of a data communications device that operates an input output protocol and/or architecture such as Infiniband by setting a configuration parameter of the input output protocol to a first value. The configuration parameter describes, to the input output protocol operating within the device, a virtual physical connectivity characteristic of the communications interface of the device to at least one other device operating the input output protocol. The system operates the device to communicate data, over the communications interface, at a first performance level corresponding to the first value of the configuration parameter and changes the first value of the configuration parameter to a second value such that the input output protocol perceives a virtual change to the physical connectivity characteristic of the device without the device experiencing an actual change to its physical connectivity characteristic of the communications interface.

Abstract: A system and method of routing requests received from client computers. The client computer processor is redirected to a router for which the address is within the preferred coverage zone. If a router is not identified for which the address is within a preferred coverage zone, but a router other than the router that received the request is identified for which the address is within a regular coverage zone, the processor is redirected to the router for which the address is within the regular coverage zone. If a message is transmitted from a router behind a firewall to a router outside the firewall, and then a request for data is received from a processor behind the firewall, the processor is redirected to the address of the router. Routers register themselves dynamically into a hierarchy. In another alternative embodiment, a service request from a particular client computer is serviced immediately by the root router rather than redirected to another router.
