  • Patent number: 11341547
    Abstract: Disclosed are various embodiments for real-time detection of duplicate data records. A duplicate detection application generates a set of clusters from a set of data records by grouping each data record in the set of data records according to similarity to respective centroid data records of the set of clusters. The duplicate detection application determines whether a particular data record has a potential duplicate in the set of data records by first comparing the particular data record to the respective centroid data records to identify a most similar cluster in the set of clusters. The duplicate detection application then compares the particular data record to each data record in the most similar cluster.

  • Patent number: 10776737
    Abstract: A system for generating operational metrics data for a medical care facility includes a first camera and an operational metrics device. The first camera generates digital images of a first detection area. The operational metrics device includes an optical code detector, a medical object detector, and an operational metrics generator. The optical code detector generates optical code detection data indicative of the presence or absence of optical codes within each of the digital images. Each of the optical codes is disposed on a respective medical object. The medical object detector generates medical object detection data indicative the presence or absence of each medical object within the first detection area. For each medical object, the operational metrics generator generates operational metrics data based at least partially on a determined amount of time that each medical object was present within the first detection area.

  • Patent number: 10659842
    Abstract: This document describes techniques using, and devices embodying, integral program content distribution. These techniques and devices enable a request for program content to be received from an end-user device. In response to the request, an integral version of the requested program content is determined using an indication of a program content transition that corresponds to an apparent broadcast time of the requested program content. The program content can be transmitted to the end-user device as part of a cloud-based digital video recorder (DVR) system.

  • Patent number: 10584415
    Abstract: A temperature controlled showerhead for chemical vapor deposition (CVD) chambers enhances heat dissipation to enable accurate temperature control with an electric heater. Heat dissipates by conduction through a showerhead stem and fluid passageway and radiation from a back plate. A temperature control system includes one or more temperature controlled showerheads in a CVD chamber with fluid passageways serially connected to a heat exchanger.

  • Publication number: 20200061229
    Abstract: An air fragrance diffuser system for use in an automobile includes a battery and an electronic control system communicably coupled to a wireless transceiver associated with a user. The diffuser system includes an air pump for generating a pressurized air. The diffuser system further includes an atomizer device pneumatically coupled to the air pump for receiving the pressurized air to convert fragrance oil stored in the atomizer device into fragrance mist using the pressurized air based on a jet nebulization process. In an embodiment, the diffuser system further includes a transmission system coupled to the atomizer device for receiving the fragrance mist, and for providing the fragrance mist into a passenger compartment of the automobile. In another embodiment, the transmission system provides the mixture into the passenger compartment using existing vents of a Heating, Ventilation, and Air Conditioning (HVAC) system of the automobile.

  • Patent number: 10560609
    Abstract: A system includes at least two capture devices, each switchable from a respective idle mode to a respective recording mode upon receipt of a trigger signal from a trigger via a network. A controller saves data packets generated by the capture devices during the respective idle modes to a short-term memory, and saves data packets generated during the respective recording modes to a long-term memory such that the data packets form respective saved data streams. The synchronizer sends a sync signal to the capture devices via the network. The compensator determines respective delay periods between sending of the sync signal by the synchronizer and receipt of the sync signal by each of the capture devices, and transfers from the short-term memory to the long-term memory any data packets generated during the respective delay period.
