A gateway application in a content engine multiplexes requests for real-time content to servers that, in turn, service the requests by streaming appropriate real-time content to requesting users. A software communication port of the content engine may be reserved to receive request messages from multiple client computers, at least two of which request streaming of real-time content according to different selected formats. After identifying client properties (e. g. , a format for which to receive streaming real-time content) associated with the requests for real-time content, the gateway application identifies corresponding servers of the content engine to serve the real-time content according to the different selected formats. The gateway application forwards the requests for streaming of real-time content associated with the request messages to the corresponding servers which, in turn, satisfy the requests by streaming the requested real-time content to the client computers.

Improved position estimation for a square photodetector having terminals at its corners is provided by first estimating an event position in a coordinate system aligned with the diagonals of the square, and then performing a coordinate rotation to provide an estimated position in a coordinate system aligned with the sides of the square. These two steps can also be mathematically combined. It is believed that the improved accuracy of this position determination approach is a result of a greater degree of linearity in charge division between terminals along diagonal axes than along orthogonal axes of a square detector. Flood images provided by this method have been compared to flood images provided by the conventional Anger method, and substantially less image distortion is observed with the present method than with the Anger method. This reduced distortion can enable automatic crystal segmentation from raw flood image data, which is particularly beneficial in connection with simplifying positron emission tomography (PET) system calibration.

Disclosed are methods and apparatus for guaranteeing restoration of traffic between one or more cable modems and a backup cable modem termination system upon failure of an active cable modem termination system are disclosed. Subscriber information associated with one or more cable modems are received from an active cable modem termination system. The subscriber information includes one or more subscriber identifiers. For instance, the subscriber information may include a primary subscriber identifier that identifies a particular cable modem as well as a secondary subscriber identifier that is assigned to high priority traffic such as that being transmitted in real-time. In addition, the subscriber information may also include a scheduling type that is further used to categorize the real-time traffic, such as into voice or video traffic. The subscriber information is then prioritized in an order in which the transmission of messages between the one or more cable modems and the backup cable modem are to be restored. For instance, the subscriber information may be prioritized according to time of receipt of the subscriber information, presence of secondary subscriber identifier, and/or scheduling type.

A provisioning server has a port to receive a request for a network address including an indication that a remote device is wideband capable. The provisioning server also has a processor to respond to the request with a network address and include an address for a configuration file and to provide a configuration file that allows wideband service. A cable modem has a port to request a network address and indicate wideband capability. The cable modem also has a processor to receive a response to that request that includes a network address and an address for a configuration file. The processor also receives a configuration file and allows the cable modem to be configured for wideband service.

A programmable logic device (PLD), is provided that includes: a plurality of SERDES channels; a programmable logic fabric configured to implement an interface for a standardized cellular base station system; wherein the interface receives data words from the SERDES channels and transmits data words to the SERDES channels, and wherein a standard corresponding to the standardized base station system restricts a latency with regard to flow of the data words through the interface, the data words being arranged into frames; and a timing measurement circuit configured to measure a delay between a detection of a first timing point in the frames at first location in the PLD with respect to the interface and a detection of a second timing point in the frames at a second location in the PLD with respect to the interface.

The invention is drawn to novel nanostructures comprising hollow nanospheres and nanotubes for use as chemical sensors, conduits for fluids, and electronic conductors. The nanostructures can be used in microfluidic devices, for transporting fluids between devices and structures in analytical devices, for conducting electrical currents between devices and structure in analytical devices, and for conducting electrical currents between biological molecules and electronic devices, such as bio-microchips.
