    摘要: A power gated variable hop cycle beam laydown (700) manifests itself as first cells (C, D) supported by a first hop cycle, second cells (G, H) supported by a second hop cycle, and transition cells (E, F) supported by a transition hop cycle. The transition hop cycle uses power gating to transition the laydown (700) from cells (C, D) operating at the first hop cycle to cells (G, H) operating at the second hop cycle. To this end, the transition hop cycle power gates its downlink beam for a portion of time needed to reduce interference between nearby (e.g., adjacent) cells.

    摘要: A frame signal (100) for communicating payloads (104, 110) of data includes a first payload field (104) and a first header field (102) with a first frame type indicator (120). The frame signal (100) also includes a second payload field (110) and a second header field (108) smaller than the first header field (102) that includes a second frame type indicator (128). The first payload field (104), first header field (102), second payload field (110), and the second header field (108) are encapsulated in a single frame (100) to provide multiple payload delivery with reduced overhead compared to individually transmitted single payload frames.

    摘要: A downlink beam frame signal processing system (100) for a communication satellite includes a packet switch (608) that routes self addressed uplink data to a memory (804). The memory (804) stores queues for at least a first and a second downlink beam hop locations (302, 304). The processing system (100) also includes a power amplifier (108) that amplifies a waveform formed using the uplink data. A power gating circuit (1200) coupled to the power amplifier (108) includes a power gate input (1216) responsive to a power gating signal to remove RF power from at least a portion of the waveform before transmission.

    摘要: A downlink frame processing system (200) includes a packet switch (608) routing self addressed uplink data (706) from an input port to an output port, a memory (804) coupled to the output port, and a downlink scheduler (802) coupled to the memory (804). The memory (804) includes storage for at least two downlink beam hop locations (302, 304). The downlink scheduler (802) processes from one of a plurality of segments at least one scheduling entry (1312) that includes, for example, a header field (1316) defining at least one of a payload and frame type (1404) for at least one of a payload and frame (1200) to be transmitted, and payload data pointers (1502, 1504, 1506) into the memory (804).

    摘要: RFID tags are configured to adjust their clock frequency in order to meet predefined limits for reply frequencies to conserve tag power. A deviation of computed tag reply frequency from a reader commanded reply frequency is used to determine an adjustment to the tag clock frequency. The tag clock frequency may be adjusted during backscatter and restored once backscattering is completed.

    摘要: A thin film heater includes at least two open regions formed along each of two spaced-apart edges of the thin film material, which edges are parallel to two spaced-apart edges of the underlying substrate. The open regions expose areas of underlying substrate. When electrical power is coupled to the two spaced-apart edges of the thin film material, uniformity of the heat generated across the thin film material is enhanced. The substrate may be planar or curved, and the open regions in the thin film material may be removed from deposited thin film material, or may be formed by preventing deposition of thin film material in such regions.
