  • Patent number: 5757416
    Abstract: A multiplex frame format for transmitting digital data in a data transmission system comprises a PACKETS portion comprising a highly error-protected region and a region having only Reed Solomon encoding as an error protection measure, the PACKETS portion including low speed data. The frame format also comprises portions for transmitting medium (AUDIO) and high speed (VIDEO) data streams following the PACKETS portion. Prior to transmission, the composed frame comprising the PACKETS, AUDIO and VIDEO portions is interleaved and the BLOCK SYNC and FRAME SYNC are added. A multiplex structure control packet word of the PACKETS portion immediately follows FRAME SYNC. Thus, the FRAME SYNC word defines where interleaving begins. A demultiplexer in concert with a microcontroller of a decoder decodes the multiplex structure control word and related PACKETS and outputs digital data streams to related output peripheral processors.

  • Patent number: 5754027
    Abstract: A battery pack (12) comprises current sensor (28) for sensing the charge current through a battery cell (26), and generating a DC voltage which is sensed by a charger (14). The charger can then provide an output current that satisfies both the need for a constant charge current through the battery cell or cells, and the varying current demand of a load (10). Additionally, the battery pack may include a switch (34) for removing the current sensor from the discharge path of the battery cell or cells and the load when the battery pack is not connected to the charger.

  • Patent number: 5733410
    Abstract: A labeling head (22) has an applicator surface (24) having an outward curvature for holding a label (12) and applying it to a labeling surface (16) of an article (14). The labeling head is rotatable about a pivot pin (38) which passes through a pivot end (28) of the labeling head, allowing a free end (26) of the labeling head to be biased toward the article at an initial angle of bias, as determined by, for example, an adjustment screw (40). The initial angle of bias and the curvature of the labeling head are such that the portion of the label nearest the free end is parallel to the labeling surface. As the labeling head is lowered, the label is applied with a substantial rolling motion to avoid trapped air bubbles.

    Abstract: A method for preparing a lithiated transition metal oxide electrochemical charge storage material for use in an electrochemical cell. The cell (10) includes a cathode (20), an anode (30) and an electrolyte (40) disposed therebetween.

  • Patent number: 5714053
    Abstract: A method for making high power electrochemical capacitors (20) provides for depositing an electrically conducting polymer (24) onto a metal substrate (22). The electrically conducting polymer is initially grown in the presence of a soft anion, i.e., an anion having a high degree of polarizability. Subsequently, the polymer is treated with a relatively hard anion which at least partially replaces the soft anion in the polymer. The result is an electrochemical charge storage device which has enhanced electrochemical properties.

  • Patent number: 5714863
    Abstract: The power delivery of an energy source (10) is enhanced by a dual function circuit. The circuit utilizes a storage capacitor (32) to store a voltage higher than the source voltage by transferring charge from the energy source to the storage capacitor between current pulses (16), than transferring charge from the storage capacitor to the load during current pulses. This is achieved by the novel combination of a boost converter (40) operating in conjunction with a buck converter (45).
