  • Publication number: 20100146878
    Abstract: The present invention relates generally to the photovoltaic generation of electrical energy. The present invention relates more particularly to photovoltaic roofing products for use in photovoltaically generating electrical energy. One aspect of the invention is a photovoltaic roofing element comprising: a flexible roofing substrate; a photovoltaic element disposed on the flexible roofing substrate; and an electrical connector operatively coupled to the photovoltaic element, wherein the flexible roofing substrate has formed therein a recess shaped to at least partially receive the electrical connector.

  • Publication number: 20070094018
    Abstract: A method for transcoding a bit stream encoded according to a mixed-excitation linear prediction (MELP) standard to a bit stream encoded according to a linear predictive coding (LPC) standard, including: decoding a bit stream into a first set of vocoder parameters compatible with the MELP standard; transforming the first set of vocoder parameters into a second set of vocoder parameters compatible with the LPC standard without converting the first set of vocoder parameters to an analog or digital waveform representation; and encoding the second set of vocoder parameters into a bit stream compatible with the LPC vocoder standard.

  • Publication number: 20070056151
    Abstract: A stent, an intermediate article in the manufacture of a stent, and a method of forming a stent from a workpiece are disclosed. A portion of the wall thickness of a workpiece may be removed, demarcating the structural framework of a stent from the remainder of the workpiece material during a cutting process. In some embodiments, a residuum layer of material remaining after a cutting process may have a recessed surface in relation to a first surface of the structural framework of the stent formed in the workpiece. In some embodiments, a plurality of kerf channels may be cut in a workpiece to demarcate a structural framework of a stent from waste material of the workpiece. In some embodiments, a series of perforations may, at least in part, demarcate the structural framework of a stent from the remainder of the workpiece material. The waste material and/or residuum material may be removed from the structural framework of a stent during a post-cutting process.

  • Publication number: 20070055512
    Abstract: The system and method of the present invention comprises a compressed domain voice activity detector that detects the presence or absence of voice activity in a digital input signal. The method includes converting a digital input signal into parametric data. The parametric data is subsequently analyzed, and then compared against a background noise threshold to determine if voice activity is present.

  • Publication number: 20050160891
    Abstract: A hybrid liquid-jet/laser device may be used to remove material from a tube or sheet to form a medical device, such as a stent. The liquid-jet/laser stream may be impinged against the wall of the tube or sheet between the ends of the tube or sheet, wherein an aperture may be formed in the tube or sheet, followed by a lead-in, and then a full thickness cut. A full thickness cut should be achieved via a lead-in before moving the liquid-jet/laser stream along a final cut path.

  • Publication number: 20050159943
    Abstract: The system and method of the present invention comprises a compressed domain universal transcoder that transcodes a bit stream representing frames of data encoded according to a first compression standard to a bit stream representing frames of data according to a second compression standard. The method includes decoding a bit stream into a first set of parameters compatible with a first compression standard. Next, the first set of parameters are transformed into a second set of parameters compatible with a second compression standard without converting the first set of parameters to an analog or digital waveform representation. Lastly, the second set of parameters are encoded into a bit stream compatible with the second compression standard.
