  • Publication number: 20240137266
    Abstract: A system is disclosed that monitors endpoints such as video cameras and audio devices for malfunction through a novel TDMA device allocation format. The system isolates and analyzes a set of groups of video streams in a rotating and recurring fashion and generates alerts and remedial commands based on the analysis. The system also provides endpoint management functions such as password analysis and firewall functions.

  • Patent number: 11219304
    Abstract: A paint brush device with a controlled paint flow system is an apparatus that facilitates efficient painting process, by providing the user with a paint brush with a reservoir handle. The inside of the reservoir handle contains the user's choice of paint. In order to transfer the paint to a plurality of bristles, the reservoir handle is internally connected to a soft, liquid repellent internal tube, that traverses internally from the reservoir handle towards the plurality of bristles on a removable brush head. The reservoir handle is compressible, therefore when manually compressed, paint travels from the reservoir handle to the plurality of bristles allowing the user to begin the painting process with little to no preparation. Further, the user can allow, control, and stop the paint flow via a control screw. Therefore, the paint brush device decreases preparation time as well as clean-up time efficiently.

  • Patent number: 8661838
    Abstract: Described is a method as well as an apparatus for vacuum cooling of food produce through moisture removal, which method comprising the steps of loading the food produce to be cooled into a vacuum chamber, lowering the pressure inside the vacuum chamber to a predetermined pressure level and maintaining the vacuum chamber at this predetermined pressure level both by removing air through a vacuum pump system for a sufficient of time to allow heat transfer out of the food produce to take place, and condensing water vapor inside the vacuum chamber through a refrigeration system. The method and apparatus is unique in that the step of lowering the pressure inside the vacuum chamber to the predetermined pressure level is carried out using a single stage vacuum pump and the step of maintaining the vacuum chamber at this predetermined pressure level is carried out using a two stage vacuum pump.

  • Patent number: 6479740
    Abstract: A method for the simulation of a realistic reverse tape effect, in real time, comprising the steps of detecting the beginning of a note by monitoring the input audio signal to determine when the same exceeds a variable amplitude threshold for a predetermined period of time and initially modulating audio signal gain with a rising exponential, while simultaneously recording the note attack and initial portion of the note decay period in digital memory, and when the input note amplitude envelope has decayed to a predetermined percentage of its peak value, stopping recording and beginning playback of the previously stored portion of the note decay and attack dynamic, in reverse, with a fixed signal gain.

  • Patent number: 5090291
    Abstract: Apparatus for converting an input note signal of the type having a rapid rise and a slow exponential decay into an output note signal which, from the shape of its envelope, appears to be a time reversed version of the input note signal includes a device which forms a normalized envelope signal, En, and a gain modification device which modifies the instantaneous gain applied to the note signal as a function of the instantaneous amplitude of En. Ideally, the function is proportional to the inverse of the square of the instantaneous amplitude of the normalized envelope signal, En. The gain modification device in accordance with a first embodiment includes an analog-to-digital converter fed by En which addresses a ROM lookup table containing data words corresponding to gain amplitudes.

  • Patent number: 4160402
    Abstract: Apparatus for converting the relatively rapid rise time, relatively long fall tone envelopes of a music source output to envelopes having relatively long rise time and relatively rapid fall time and for also varying the frequency of the tone in the nature of the Doppler effect of an accellerating source provides the modulation input to cascaded phase and amplitude modulators fed by the music source.

  • Patent number: 4003285
    Abstract: Apparatus for converting the relatively rapid rise time, relatively long fall time tone envelopes of a music source output to envelopes having relatively long rise time and relatively rapid fall time includes a sawtooth relaxation oscillator whose output feeds a modulator which is also fed by the music source. The oscillator is turned on via a transistor switch when the average power of the signal at the output of the modulator exceeds a predetermined reference threshold signal.
