摘要： Compressive sensing is an emerging field that attempts to prevent the losses associated with data compression and improve efficiency overall, and compressive sensing looks to perform the compression before or during capture, before energy is wasted. Here, a reconstruction algorithm is proposed for a compressive sensing successive approximation register (SAR) analog-to-digital converter (ADC). Accordingly, an analog signal is converted to a first digital signal at a sampling frequency that is less than a Nyquist frequency for the analog signal, and a second digital signal is constructed from the first digital signal with a box constrained linear optimization process such that the second digital signal is approximately equal to an analog-to-digital conversion of the analog signal at the Nyquist frequency for the analog signal.

摘要： A calibration method to compensate for a sparsifying basis mismatch is provided. An analog signal is converted to a first digital signal at a sampling frequency that is less than a Nyquist frequency for the analog signal to generate a first digital signal. Each of a plurality of spectral terms is iteratively isolated from the first digital signal, and the offset for each of the plurality of spectral terms is iteratively determined. A dictionary is then constructed using the offset for each of the plurality of spectral terms, where the dictionary compensates for mismatch from a sparsifying basis.

摘要： Provided are methods, apparatus and computer program products for switching between data streams. The data streams include a matching set of data items in a consistent sequence. One data stream may be a superset of the other, and which data stream is running ahead of the other may not be known in advance. It is desired to synchronize the data streams so that a data receiver can be switched from a first to a second data stream without loss of data. For a time period of interest, characteristics of a first data item on one stream are compared with characteristics of each latest-received data item on the other stream until a match is identified. This match is used to identify a synchronization point for the switch between data streams.

摘要： A conveyor belt cleaner including a biasing mechanism and a scraping member removably attached to the biasing mechanism. The biasing mechanism includes an inner coupler member having a base and a plurality of inner fins extending outwardly from the base. An outer coupler member includes a peripheral wall that extends around the inner coupler member. A plurality of outer fins extend inwardly from the peripheral wall of the outer coupler member with each outer fin being located between a pair of adjacent inner fins such that a cell is respectively formed between each adjacent inner fin and outer fin. A biasing member formed from a resilient elastomeric material is located between the inner and outer coupler members and includes a one or more first lobes and one or more second lobes. The first and second lobes are located alternately with respect to one another with each lobe being located in a respective cell. The inner fins and outer fins place the first lobes of the biasing member in compression, and place of the second lobes of the biasing member in tension, as the outer coupler member rotates with respect to the inner coupler member from a first position toward a second position, such that the first and second lobes resiliently bias the outer coupler member and the scraping member from the second position toward the first position.
