    摘要： Systems, components, and methods for tracking, monitoring, and optionally reminding for use with hospitals, businesses, and office buildings. The components of the systems can include wearable advertising devices (WAD) that emit BLE signals, repeaters and/or gateways for receiving and relaying the BLE signals over a BLE Mesh network to a remote server. IR codes can be included to detect the presence of a WAD before the WAD is energized to emit a BLE signal.

    摘要： Methods and systems for sample rate conversion convert a sampled signal to a higher data rate signal. Conversion pulses are received, having a conversion rate that is higher than the sample rate of the sampled signal. Sample points are then reconstructed from the sampled signal, in real time, on either side of a conversion pulse. An interpolation is performed between the reconstructed sample points, at the time of the conversion pulse. The interpolation results are outputted in real time. The process is repeated for additional conversion pulses. The outputted interpolated amplitudes form the higher data rate signal having a data rate equal to the conversion rate. Sample rate conversion is thus performed in real time according to the higher data rate clock, rather than with fixed ratios. As a result, when the higher data rate clock is affected by, for example, jitter or other frequency variations, the higher data rate samples immediately track the lower data rate samples. This helps to insure that the output higher data rate data tracks the lower rate data, thus providing a more accurate sample rate conversion.

    摘要： A method and apparatus for manipulating digitized images stored as variable length encoded bitstreams such as JPEG format in a manner that reduces memory and processor resource requirements. A prescan means sequentially decompresses the bitstream to identify the location of encoded pixel image areas. Designated ones of these locations are recorded or stored in a prescan table. After the prescan operation has been performed on the image, image manipulations such as rotating, cropping, and zooming can be performed on a selected portion of the image by directly accessing only the encoded pixel image areas to be manipulated, without the need to sequentially decode and store all the encoded image areas in order to locate the ones of interest.

    摘要： A digital signal processor having a programmable address generator. In an embodiment, the programmable address generator enables an execution unit of the digital signal processor to perform register addressing, indirect addressing, and immediate addressing in response to a single arithmetic instruction. The digital signal processor is useful for implementing, for example, reprogrammable decoders and digital filters. In one embodiment, the digital signal processor is used to implement a US/Japan BTSC decoder.
