Embodiments of the invention enable minimum latency site independent real-time video transport over packet switched networks. Some examples of real-time video transport are video conferencing and real-time or live video streaming. In one embodiment of the invention, a network node transmits live or real-tine audio and video signals, encapsulated as Internet Protocol (IP) data packets, to one or more nodes on the Internet or other IP network. One embodiment of the invention enables a user to move to different nodes or move nodes to different locations thereby providing site independence. Site independence is achieved by measuring and accounting for the jitter and delay between a transmitter and receiver based on the particular path between the transmitter and receiver independent of site location. The transmitter inserts timestamps and sequence numbers into packets and then transmits them. A receiver uses these timestamps to recover the transmitter's clock. The receiver stores the packets in a buffer that orders them by sequence number. The packets stay in the buffer for a fixed latency to compensate for possible network jitter and / or packet reordering. The combination of timestamp packet-processing, remote clock recovery and synchronization, fixed-latency receiver buffering, and error correction mechanisms help to preserve the quality of the received video, despite the significant network impairments generally encountered throughout the Internet and wireless networks.

A phased transactional memory (PhTM) may support a plurality of transactional memory implementations, including software, hardware, and hybrid implementations, and may provide mechanisms for dynamically transitioning between transactional memory modes in response to changing workload characteristics; upon discovering that the current mode does not perform well, is not suitable, or does not support functionality required for particular transactions; or according to scheduled phases. A system providing PhTM may be configured to transition from a first transactional memory mode to a second transactional memory mode while ensuring that transactions executing in the first transactional memory mode do not interfere with correct execution of transactions in the second transactional memory mode. The system may be configured to abort transactions in progress or to wait for transactions to complete, be aborted, or reach a safe transition point before transitioning to a new mode, and may use a global mode indicator in coordinating transitions.

Light from an object such as a cell moving through an imaging system is collected and dispersed so that it is imaged onto a plurality of separate detectors. The light is spectrally dispersed by a plurality of spaced-apart dichroic reflectors, each detector receiving light from a different one of the dichroic reflectors. Each dichroic filter reflects light of a different predefined color, passing light of other colors. The output signal from each detector is indicative of a different characteristic of the object. In one configuration, each detector is provided with a separate imaging lens. In another configuration, the detectors are spaced at varying distances from the corresponding dichroic reflectors, so that separate imaging lenses are not required.

A distributed Internet Protocol (IP) voting system and method for use in Land Mobile Radio (LMR) Systems having a central send-and-receive site and one or more receive-only sites. In the distributed voting system, receive-only sites are directly linked to the control point using a network and associated packet transmission protocol. This may be a high-speed asynchronous data link such as a standard IP network link. Each remote site receiving digital data, calculates a bit error for that data. This error calculation is incorporated into the data header information. The data header information and data are placed in an IP packet and transmitted as a User Data Protocol (UDP) message to the control point. The control point selects the lowest bit rate data message, or the first control message, and retransmits it using a standard radio air interface protocol, such as the APCO Project 25 air interface protocol.

The method is based on the mobile station using information in a neighboring cell information message (e.g. the MNCI message in case of an MBMS session) or other message (possibly specially defined) before changing to the new cell to determine the bearer information for the system information channel in the new cell (and also obtaining from the neighboring cell information the bearer information for receiving the point-to-multipoint transmission in the new cell).

An electrically continuous, grounded conformal EMI protective shield and methods for applying same directly to the surfaces of a printed circuit board. The EMI shield adheres and conforms to the surface of the components and printed wiring board. The shield takes the shape of the covered surfaces while adding little to the dimensions of the surfaces. The EMI shield includes low viscosity, high adherence conductive and dielectric coatings each of which can be applied in one or more layers using conventional spray techniques. The conductive coating prevents substantially all electromagnetic emissions generated by the shielded components from emanating beyond the conformal coating. The dielectric coating is initially applied to selected locations of the printed circuit board so as to be interposed between the conductive coating and the printed circuit board, preventing the conductive coating from electrically contacting selected components and printed wiring board regions. A high viscosity, non-electrically-conductive filler material is applied to printed circuit board regions that have surfaces that are cavitatious and / or which have a highly variable slope. The filler material can be used in conjunction with conformal EMI shield board level coating. The high viscosity, electrically non-conductive filler material substantially covers each cavity such that the covered cavity is inaccessible and that the covered region of the printed circuit board has a contiguous, contoured surface. A pre-manufactured non-electrically-conductive component cover can be mounted over a corresponding component and secured to the printed wiring board. The component cover and printed wiring board surround the component, forming a sealed enclosure. The component cover has a thin cross-section and an interior surface that follows closely the surface of the component. This minimizes the volume enclosed by the component cover. In addition, the exterior surface of the component cover has a low profile, and prevents the conformal EMI shield from physically contacting the covered component. Instead, the exterior surface of the component cover is coated with the EMI shield. This enables the covered component to be removed from the printed circuit board for repair, replacement or salvage without having to risk damage to the printed wiring board or component that may occur with the removal of a conformal EMI shield applied directly to the component.

The constraints of the CSP are reformulated so as to perform at least one of increasing a density of the solutions in the problem topography and smoothing a gradient of the problem topography. One or more of the solutions of the CSP are found by applying a stochastic CSP solver to the reformulated constraints.
