  • Publication number: 20060156200
    Abstract: A resource allocation of multiple compressed AV streams delivered over the Internet is disclosed that achieves end-to-end optimal quality through a multimedia streaming TCP-friendly transport (MSTFP) protocol that adaptively estimates the network bandwidth while smoothing the sending rate. Resources allocated dynamically according to a media encoding distortion and network degradation algorithm. A scheme is also disclosed for dynamically estimating the available network bandwidth for streaming of objects, such as MPEG4 multiple video objects, in conjunction with the MSTFP protocol. The scheme can account for packet-loss rates to minimize end-to-end distortion for media delivery.

  • Patent number: 7074537
    Abstract: Liquid electrographic toners are derived from organosols incorporating amphipathic copolymeric binder particles that include polymerizable, crystallizable compounds chemically incorporated into the dispersed portion of the copolymer. The invention further provides organosols that include amphipathic copolymeric binder particles that include a dispersed (D) portion and a solvated (S) portion, wherein the D portion has a high glass transition temperature, and at least one polymerizable, crystallizable compound is chemically incorporated into the D portion, the S portion, or both the D and S portion of the copolymer. Methods of making and electrographically printing liquid toners derived from these organosols are also described. The invention is particularly suited for preparing liquid toners for electrophotographic printing.

  • Publication number: 20060145776
    Abstract: The voltage-controlled oscillator (VCO) in a frequency synthesizer using a phase-locked loop (PLL) is calibrated digitally during power up. The VCO has a coarse frequency control and a fine frequency control. The coarse control is a digital phase-locked loop to quantize the broad frequency range into limited number of frequency steps with a clock frequency divided from the VCO frequency, and to hold the phase-locked dc control voltage for the fine control. By limiting the number of frequency steps and clocking at a divided frequency of the VCO, the coarse control is speeded up. The fine control is [connected to the charge pump output as in] a regular PLL. By searching for the optimal control setting, the center frequency of the VCO is trimmed close to the wanted frequency for the PLL to lock. This allows small VCO gain without losing the tolerance of process and temperature variations. As a result, the PLL phase noise performance is improved.

  • Publication number: 20060139223
    Abstract: An antenna for receiving and/or transmitting circularly and/or linearly polarized RF signals includes a radiation element, a ground plane, a dielectric substrate, and a feed line. The radiation element is disposed on a pane of glass. The radiation element defines a slot having a first leg and a second leg forming the shape of a cross for generating the circular and/or linear polarization. The cross-shaped slot includes a center point. The ground plane is disposed substantially parallel to and spaced from the radiation element. The dielectric substrate is sandwiched between the radiation element and the ground plane. The feed line extends within the dielectric substrate and is electromagnetically coupled with the radiation element and the ground plane. The feed line terminates at a distal end short of the center point of the slot. That is, the feed line does not cross the center point. The antenna is compact in size and generally conformal to the pane of glass.
