  • Publication number: 20260061145
    Abstract: A respiratory monitoring system with improved detection of oxygen consumption is described.

  • Publication number: 20250342327
    Abstract: A system comprises a radio frequency identification (RFID) reader, a presence detector, and at least one processor operationally coupled to the RFID reader and the presence detector. The at least one processor determines, whether a RFID tag and a RFID tag read time are identified; determine, via the presence detector, a last movement time period; determines whether the RFID tag read time is within the last movement time period; determines whether the RFID tag is on a tag list and update the RFID tag to a tag list when the RFID tag read time is within or not within the last movement time period and RFID tag is on the tag list, or add the RFID tag to a stray list when the RFID tag read time is within or not within the last movement time period and the RFID tag is not on tag list.

  • Publication number: 20250107922
    Abstract: A cryoprotectant for use with a treatment device for improved removal of heat from subcutaneous lipid-rich cells of a subject having skin is provided. The cryoprotectant is a non-freezing liquid, gel, or paste for allowing pre-cooling of the treatment device below 0° C. while preventing the formation of ice thereon. The cryoprotectant may also prevent freezing of the treatment device to the skin or ice from forming from moisture seeping out from the skin. The cryoprotectant may further be hygroscopic, thermally conductive, and biocompatible.

  • Patent number: 12097467
    Abstract: Membrane filtration systems can be used to purify liquid streams for downstream use. In practice, foulant can build-up on the surface of a membrane within a filtration system over time. The effectiveness of the filtration system will deteriorate if the fouling is not properly controlled. In some examples, a method of controlling membrane fouling in a pressurized membrane system involves supplying a feed stream that is predominately air mixed with water to the membrane. In other words, the feed stream a greater volume of air than water, even though it is the water being processed by the membrane. Supplying the pressurized membrane system with a feed stream that contains a greater volume of air than water can yield significantly better performance than supplying the membrane with a feed stream that contains a greater volume of water than air.

  • Publication number: 20240084395
    Abstract: Single-stranded oligonucleotide probes, systems, kits and methods for chromosome enumeration, gene copy enumeration, or tissue diagnostics. The probes are particularly suited for detecting gene amplification, deletion, or rearrangement in tissue samples in a single, dual, or multiplexed assay. The probes exhibit improved performance compared to industry leading dual-stranded probes; particularly in terms of the rate of hybridization.

  • Patent number: 11662727
    Abstract: A wide-area motion imaging system provides 360° persistent surveillance with a camera array that is small, light-weight, and operates at low power. The camera array is mounted on a tethered drone, which can hover at heights of up to 400?, and includes small imagers fitted with lenses of different fixed focal lengths. The tether provides power, communication, and a data link from the camera array to a ground processing server that receives, processes and stores the imagery. The server also collects absolute and relative position data from a global positioning system (GPS) receiver and an inertial measurement unit (IMU) carried by the drone. The server uses this position data to correct the rolling shutter effect and to stabilize and georectify the final images, which can be stitched together and shown to a user live or in playback via a separate user interface.

  • Patent number: 11258706
    Abstract: An example path discovery system includes a memory and processing circuitry in communication with the memory. The processing circuitry is configured to obtain routing script metadata associated with a telephony network, to parse routing logic implemented by one or more nodes of the telephony network, to emulate, using the routing script metadata and the parsed routing logic, a traversal path for a call through the telephony network, the emulated traversal path including the one more nodes for which the routing logic is parsed, to store, to the memory, the emulated traversal path and respective final states of runtime variables associated with the one or more nodes included in the emulated traversal path, and to generate, in a machine-readable format, one or more reports indicating a destination of the emulated traversal path in the telephony network and an ingress of the emulated traversal path with respect to the telephony network.

    Abstract: A method for performing a multiplexed diagnostic assay, such as for two or more different targets in a sample, is described. One embodiment comprised contacting the sample with two or more specific binding moieties that bind specifically to two or more different targets. The two or more specific binding moieties are conjugated to different haptens, and at least one of the haptens is an oxazole, a pyrazole, a thiazole, a nitroaryl compound other than dinitrophenyl, a benzofurazan, a triterpene, a urea, athiourea, a rotenoid, a coumarin, a cyclolignan, a heterobiaryl, an azo aryl, or a benzodiazepine. The sample is contacted with two or more different anti-hapten antibodies that can be detected separately. The two or more different anti-hapten antibodies may be conjugated to different detectable labels.

  • Patent number: 11019466
    Abstract: The vehicle-locating flag is a signal device. The vehicle-locating flag is configured for use with a vehicle. The vehicle further comprises a door and an electrical system. The vehicle-locating flag attaches to the door of the vehicle. The vehicle-locating flag is configured for use with a fob. The vehicle-locating flag comprises a display structure and a control circuit. The display structure visibly displays the location of the vehicle. The control circuit operates a strobe light that draws attention to the location of the display structure. The control circuit transmits an SMS message containing the location of the vehicle over a commercially provided and publicly available cellular wireless network to a personal data device. The fob transmits a radio frequency signal to initiate the operation of the control circuit.

  • Patent number: 10978189
    Abstract: A computing entity accesses instances of medical information corresponding to a population of patients and generates a plurality of medical sentences corresponding to the population by, for each patient of the population, generating one medical sentence corresponding to the patient and a timestamp associated with each instance such that the one medical sentence comprises one or more medical codes in a chronological order. The computing entity generates a vector dictionary comprising a plurality of multi-dimensional vectors based on a vector generation model trained using machine learning and the plurality of medical sentences with each multi-dimensional vector corresponding to a medical code. The computing entity generates a digital representation of a first patient of the population using an anagram model and the vector dictionary, determines a health state of the first patient based on the digital representation, and provides an output indicating the health state of the first patient.
