  • Publication number: 20220051647
    Abstract: A musical device between one or more Musical Instrument Digital Interface (MIDI) controllers and one or more musical instruments comprises a housing and a plurality of potentiometers on a surface of the housing. A method of mapping music messages using a musical device is provided. The method includes defining a preset value corresponding to a frequency to be received within a MIDI message. Once a MIDI message having the frequency is received by the device, the device uses the data of the MIDI message and the preset value to create a new output MIDI message. The new output message is then transmitted to a sound module for producing a sound that differs from the sound that would have been produced from the MIDI message, had it been received.

  • Patent number: 11243054
    Abstract: Implementations of conductive energy weapons (CEWs) may include a shock generating circuit configured to couple to a power source, two electrodes operatively coupled to the shock generating circuit, and a safety circuit operatively coupled to the shock generating circuit. The shock generating circuit may be configured to generate a first pulse train and deliver the first pulse train to a target, and may be configured to generate at least a second pulse train and deliver the at least second pulse train to a target. The safety circuit may be configured to prevent the CEW from applying pulse trains to the target after a predetermined number of pulse trains. The first pulse train may include two or more pulses having waveforms substantially identical with each other, each of the waveforms of the two or more pulses having both a positive voltage segment and a negative voltage segment.

  • Publication number: 20210342881
    Abstract: In a promotion offering system, a promotion offering may be presented to a consumer on more than one occasion. The previous presentation of the promotion to the consumer may affect a subsequent presentation of the same promotion to the same consumer. The present invention provides an apparatus and method for analyzing the effect a previous presentation of a promotion may have on a consumer when the promotion is presented to the consumer at a subsequent time.

  • Publication number: 20210326921
    Abstract: A promotion system for determining a deficiency in promotion data and correcting for the deficiency is disclosed. Issuing offers from a promotion program results in promotion data being generated. The promotion data may be analyzed to determine an acceptance rate of the offers. The promotion system may compare whether the acceptance rate is above a predetermined threshold, but has a confidence level that is less than a confidence rate threshold. In that event, the promotion system may issue additional offers in order to increase the confidence level associated with the acceptance rate by a predetermined amount.

  • Publication number: 20210209642
    Abstract: A promotion offering system and method is disclosed. The promotion offering system and method selects consumers for a test promotion that has one or more attributes, and is configured to generate test data for multiple consumer groupings. The promotion offering system and method may use the test data in analyzing whether to send a promotion to a consumer. For example, the promotion offering system and method may use one algorithm to generate a list of ranked promotions, and may use the test data in order to adjust the list of ranked promotions (such as replacing a highest ranked promotion with another promotion).

  • Publication number: 20210140996
    Abstract: A sensor device includes a carrier, a force feedback sensor, and a probe containing a spin defect, the probe being connected to the force feedback sensor either directly or indirectly via a handle structure. In order to couple the spin defect to a microwave field in an efficient and robust manner, the sensor device includes an integrated microwave antenna arranged at a distance of less than 500 micrometers from the spin defect. The sensor device can be configured as a self-contained exchangeable cartridge that can easily be mounted in a sensor mount of a scanning probe microscope.

  • Patent number: 10936601
    Abstract: A news feed system provided with an on-line social network system determines that a news feed is to be constructed for a viewer. The news feed system accesses the viewer's profile and other information associated with the viewer, accesses an inventory of activities that have been identified as potentially of interest to the viewer, and calculates relevance score for each item inventory of activities using the combined predictions methodology. The activities are then arranged for presentation to the viewer via a news feed web page, using respective calculated relevance scores.
