  • RARE INSTANCE ANALYTICS FOR DIVERSION DETECTION
    Publication number: 20220375581
    Abstract: A method for detecting diversion may include identifying an activity pattern associated with a clinician as being an infrequent activity pattern that occurs below a threshold frequency. Whether the infrequent activity pattern corresponds to an anomalous behavior may be determined based at least on one or more data models. The infrequent activity pattern may include a series of transaction records, which may be matched to the reference transaction values included in each of the one or more data models. An investigative workflow may be triggered in response to the infrequent activity pattern being determined to correspond to the anomalous behavior. Related methods and articles of manufacture are also disclosed.

  • DOSAGE NORMALIZATION FOR DETECTION OF ANOMALOUS BEHAVIOR
    Publication number: 20220277838
    Abstract: A method may include receiving a first transaction record indicating a first interaction with a first raw quantity of a first medication and a second transaction record indicating a second interaction with a second raw quantity of a second medication. The first transaction record and the second transaction record may be normalized by generating, based on an equivalent unit, a first normalized quantity of the first medication and a second normalized quantity of the second medication. A machine learning model may be applied to the normalized first transaction record and second transaction record to detect, based on the first transaction record and the second transaction record, an anomalous behavior. An investigative workflow may be triggered in response to the machine learning model detecting the anomalous behavior. Related systems and articles of manufacture, including computer program products, are also provided.

  • Filtering out Communications Related to Unwanted Emotions on Online Social Networks
    Publication number: 20190124023
    Abstract: In one embodiment, a method includes retrieving one or more previous communications associated with a first user of an online social network, each of the previous communications having been made on a date in the past, and filtering out each of one or more of the previous communications based on one or more criteria, wherein the criteria are associated with a likelihood that the filtered-out previous communication will cause an unwanted emotional reaction by the user. The method also includes calculating a distribution-probability score for each of one or more remaining previous communications, wherein the distribution-probability score reflects a probability that the previous communication will be shared on the online social network by the first user, and sending at least one remaining previous communication to a client system of the first user, wherein the distribution-probability score for the previous communication satisfies a threshold.

    Patent number: 8645583
    Abstract: A method for controlling performance of an integrated circuit using a zero-pin serial interface is provided. The method comprises identifying a desired performance characteristic of the circuit, and transmitting a first change mode signal to the circuit on a first pin to cause the circuit to enter an instruction reception mode, with the first pin performing differently during a normal operation mode. The method also comprises transmitting a performance adjusting instruction to the circuit on a second pin when the circuit is in the instruction reception mode, with the second pin performing differently during the normal operation mode, and transmitting a second change mode signal to the circuit on the first pin to cause the circuit to enter the normal operation mode. An output performance of the circuit is compared to the desired performance characteristic, with the output performance being the performance of the circuit during the normal operation mode.

  • Automatic circuit and method for temperature compensation of oscillator frequency variation over temperature for a real time clock chip
    Patent number: RE43236
    Abstract: An automatic temperature compensated real-time clock (RTC) chip includes a clock portion having a crystal oscillator block including crystal compensation circuitry adapted to be coupled to a crystal. The crystal compensation circuitry includes a non-linear capacitor DAC including a plurality of load capacitors, wherein the load capacitors have respective switches which switch respective ones of the load capacitors to change a parallel resonance frequency (fp) generated by the oscillator block. The capacitor DAC is arranged so that Analog Trimming (ATR) bits received cause an arrangement of the switches to provide a non-linear change in overall load capacitance to result in a linear relationship between fp and the ATR bits. A temperature sensor block is coupled to the crystal for measuring a temperature of at least the crystal. An A/D converter is coupled to the temperature sensor for outputting a digital temperature signal representative of the temperature of the crystal.
