Abstract: An apparatus for detecting optical signals includes a photodetector. The photodetector is reverse-biased by a first voltage and a second voltage is added to the first voltage to provide an offset equal to the second voltage for the photodetector. A first circuit is coupled to the first circuit to provide the second voltage for the photodetector and a second circuit is coupled to the first circuit to provide the first voltage to the photodetector to reverse-bias the photodetector. The second circuit provides an output voltage proportional to a current of the photodetector at an output of the second circuit.

Abstract: An apparatus includes a first circuit that has a photodetector. The photodetector is reverse-biased by a reverse-bias voltage. A common mode voltage is added to the reverse-bias voltage to provide an offset to the photodetector voltage. A second circuit is coupled to the first circuit to provide the common mode voltage for the first circuit. A third circuit is coupled to the second circuit that includes a first voltage source and a second voltage source having opposite voltages equal to half of the reverse-bias voltage. Each one of the first voltage source and the second voltage source are coupled between separate input and output nodes of input and output ports of the third circuit. The first voltage source and the second voltage source provide the reverse-bias voltage to the first circuit to reverse-bias the photodetector. The third circuit provides a photodetector current at an output of the third circuit.

Abstract: In non-limiting examples of the present disclosure, taste data is generated and usable within one or more applications. A taste is one or more elements that describe an entity. Information of an application may be processed to extract entity data that corresponds to a plurality of candidates to be designated as tastes (taste data). The candidates for the tastes are curated. In examples, the curating comprises filtering the candidates for tastes to remove extracted candidates. Extraction rules for managing structured taste data may be applied in the filtering. A status of a remaining candidate may be determined as approved or rejected based on processing of received user feedback. Taste data may be generated for an approved candidate. The generating of the taste data may comprise assigning parameters that include a descriptor type and a recommendation type. Taste data may be used within an application.

Abstract: An algorithm for analyzing presidential preference opinion polls to arrive at a statistical snapshot of a multistate electoral-vote-allocation political race such as the US presidential race. Multiple opinion polls are used to estimate the outcome probability in individual state races. Polls are used to calculate a probability distribution of all possible electoral vote outcomes. The algorithm includes a method for calculating a median electoral vote estimator at any moment during a campaign. The electoral vote estimator can be tracked over time. The estimation of single-state probability is done using a Bayesian method to correct for sampling biases and systematic errors in polls, thereby allowing correction of the overall estimate. The algorithm calculates the relative value of an individual vote, the jerseyvote, in different states. The jerseyvote valuation aids resource allocation by a political campaign or party, an advocacy organization, or an individual activist.

Abstract: A number of different subroutines or algorithms are provided for locating lost video data, reconstructing navigation data, and creating new navigation files or the like so that the DVD may be made readable by an ordinary DVD player. The present invention provides algorithms to recover video data for each of a number of different DVD formats, so that video data may be recovered regardless of which format DVD was being used at the time (e.g., DVD+RW, DVD+R, DVD?RW, DVD?R, or the like). In addition, the present invention provides a number of other algorithms that be used by one or more of the different recovery algorithms, to recover various aspects of data from a disc. The combination of these algorithms provides a complete package of data recovery techniques that allows for video data to be recovered in the event of a power loss or other interruption, and in most instances, creates recordable DVD which may be subsequently read by other DVD players and the like.
