摘要： Devices are equipped with BLE modules that can scan, advertise, or both scan and advertise to form smart devices with beaconing capabilities. A cloud server can act as a bridge to allow a first user to remotely communicate with a second user based on the beacon generated by the smart devices. The cloud server, based on the beacon generated, can send commands to initiate one or more processes, such as to send reminders, to send open commands, or to send a digital key. Alternatively, the cloud server can act as a bridge between the first user and the second user based on the second user scanning and decoding a QR code using an app running on a smartphone used by the second user.

摘要： Communication accessories, such as keyfobs (KFs) and/or transmitter/receiver dongles, which can transmit and receive signals to enable connectivity between owners of different portable devices even when the devices are off or when in a sleep mode, are described. In some examples, the keyfobs and/or the dongles are programmed with connectivity tokens, such as being programmed with Facebook (FB) information, FB accounts or FBIDs, LinkedIn ID, or generically social network user information, that can be used to authenticate different smart portable devices belonging to different users to facilitate networking. Once the keyfobs and/or dongles are authenticated, they will buzz, sound, or otherwise alert their respective owners that one or more social network users, such as a FB user or a LinkedIn user, are within the general vicinity and that further actions through smart portable devices may be needed to connect the users.

摘要： A system and method are disclosed for performing digital multi-channel decoding of a BTSC composite audio signal. Each subsequent stage of the digital multi-channel decoding process is performed at the lowest sampling rate that yields acceptable performance for that stage. Analog-to-digital conversion of the composite audio signal is performed first to generate a composite digital audio signal. After analog-to-digital conversion, all signal processing may be performed in the digital domain. The composite digital audio signal is digitally filtered to frequency compensate for variations caused by previous stages of processing, including IF demodulation. Digital channel demodulation and filtering are performed to isolate single channels of the composite digital audio signal such as SAP, L−R, and L+R channels. SAP and L−R channels are DBX decoded resulting in corresponding decoded signals using a unique combination of digital filters that are an efficient translation of a corresponding combination of analog filters.

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： 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： Aspects of the method and system for rejecting single sided leakage into an amplitude modulated channel may comprise an AM demodulator for demodulating a received composite broadcast signal's control channel to generate an amplitude modulated (AM) component. A PM demodulator may demodulate a received composite broadcast signal's control channel to generate a phase modulated (PM) component. At least one subtractor may subtract an AM leakage component and a PM leakage component contributed by the single sided leakage in the received composite broadcast signal's control channel. The system may comprise at least one of each of AM and PM bandpass filters and envelope detectors that filter and detect envelopes of the AM and PM components at 982.5 Hz and 922.5 Hz.
