  • Publication number: 20110084656
    Abstract: A wireless transmission system having a transmitter and receiver is described. In one embodiment, the transmitter includes an electronically-controlled switch controlled by a first pulse width modulation control circuit, the switch configured to pull current through a first inductor when the switch is closed, the first pulse width modulation control circuit outputting a PWM output signal to control the switch. A first feedback signal obtained from a control input of the switch. A second feedback signal obtained from a terminal of the inductor, wherein a control feedback signal is computed, at least in part, as a difference between the first feedback signal and the second feedback signal is provided to the first pulse width modulation control circuit. In one embodiment, the receiver includes a second pulse with modulation controller, the second pulse width modulation controller controlling the receiver switch to deliver a desired power from the receiving coil to a load.

  • Publication number: 20110070820
    Abstract: Embodiments enable mobile devices to efficiently receive mobile broadcast content corresponding to a user's selections based upon content description metadata transmitted in a content description flow portion of broadcast transmissions. A content description flow may be in the form of broadcast data packets which include information about the nature of content elements to be broadcast. Using the information in the content description flow, a mobile device can determine whether a particular portion of content is of interest, as well as when the content will be broadcast and the content flow address on which it can be received. Enabling mobile devices to screen broadcast content flows by monitoring the content description flow for content of interest can extend their battery life since the content description flow can be quickly downloaded and the receiver de-energized if no content is of interest to the user.

  • Patent number: 7740057
    Abstract: The present invention provides a single shell-pass shell-and-tube heat exchanger with helical baffles, where within a single pitch, the helical baffles are separated into inner and outer parts along the radial direction of the shell. In the central portion of the inner space of the shell, an inner non-continuous helical form is employed; in other portion outside the central portion, doughnut shaped helical baffles with continuous curved surfaces are arranged to form an outer continuous helical baffle, and the outer helical baffles are arranged to surround the inner helical baffles. Furthermore, the present invention relates to a multiple shell-pass shell-and-tube heat exchanger with helical baffles, in which complete continuous helical baffles are provided in shell-sides other than the inner shell-pass, while non-continuous helical baffles or other flow guide means are employed in the inner shell-pass.

  • Publication number: 20090274099
    Abstract: Methods and apparatus for communicating transmitter information in a communication network are disclosed. The methods and apparatus communicate transmitter specific information, in particular, which includes location information about network transmitters for use in location or positioning type services. The disclosed methods and apparatus include inserting such transmitter specific information within either a data flow of at least one transmission frame or a control channel in the at least one transmission frame. In addition, a transmitter identifier is encoded in a positioning pilot channel (PPC) within the at least one transmission frame, and the configured transmission frame transmitted to a user device. The user device may use the transmitter specific information of numerous transmitters along with the transmitter identifiers to measure how far it is from the transmitters, and then triangulate to determine position.

  • Publication number: 20090016445
    Abstract: The disclosure relates to techniques for switching between channels of digital multimedia content. In particular, a decoding device decodes and renders to a display at least one frame of a segment of data prior to receiving the entire segment. In certain aspects, the decoding device may render one of the frames of the segment and freeze the rendered frame until the decoding device receives all of the frames of the segment. In other aspects, the decoding device may render frames of one or more segments at a reduced rendering rate until the receiving and rendering operations of decoding device are synchronized such that the rendering of the current segment occurs at substantially the same time as the receiving of the next segment. By rendering at least frame prior to receiving the entire segment the decoding device more quickly displays content to a user during a channel switching event.
