  • Patent number: 11351977
    Abstract: A method of operating an accessory drive system for a motor vehicle, wherein the accessory drive system includes one or more accessory components, a motor generator of the motor vehicle, and a flexible drive element configured to transmit a torque load between the one or more accessory components and the motor generator, includes determining a maximum permissible flexible drive element torque threshold, detecting an increase in torque demand on the flexible drive element, determining when the torque demand on the flexible drive element will exceed the flexible drive element torque threshold, and reducing the torque demand of one or more of the accessory components so that the flexible drive element torque threshold is not exceeded.

  • Publication number: 20220173654
    Abstract: An apparatus includes first and second pluralities of switches, a controller for controlling these switches, gate-drivers for driving switches from the first plurality of switches, and first and second terminals configured for coupling to corresponding first and second external circuits at corresponding first and second voltages. During operation, the controller causes the first plurality of switches to transition between states. These transitions result in the second voltage being maintained at a value that is a multiple of the first voltage. The controller also causes the second plurality of switches to transition between states. These transitions resulting in capacitors being coupled or decoupled from the second voltage. The gate drivers derive, from the capacitors, charge for causing a voltage that enables switches from the first plurality of switches to be driven.

  • Publication number: 20220172845
    Abstract: An application server predicts respiratory disease risk, rescue medication usage, exacerbation, and healthcare utilization using trained predictive models. The application server includes model modules and submodel modules, which communicate with a database server, data sources, and client devices. The submodel modules train submodels by determining submodel coefficients based on training data from the database server. The submodel modules further determine statistical analysis data and estimates for medication usage events, healthcare utilization, and other related events. The model modules combine submodels to predict respiratory disease risk, exacerbation, rescue medication usage, healthcare utilization, and other related information. Model outputs are provided to users, including patients, providers, healthcare companies, electronic health record systems, real estate companies and other interested parties.

  • Patent number: 11340157
    Abstract: A method of selecting wavelengths of radiation for discriminating a first cell or tissue type from a different cell or tissue type is described. First and second sets of absorption spectra are obtained, each set comprising spectra obtained at a plurality of different spatial regions of the first cell or tissue type and of the different cell or tissue type, respectively. Sets of corresponding metrics are defined for the first and second sets of absorption spectra for each spatial region. Each metric comprises information corresponding to the absorption for at least two different wavelengths. The metrics in each set comprise different combinations of wavelengths. A characteristic value is generated for each metric. Distributions are generated for each metric using corresponding characteristic values for the first cell or tissue type and for the different cell or tissue type and compared to determine an extent of similarity.

  • Patent number: 11235852
    Abstract: A bi-directional egress hatch for a passenger aircraft may allow passengers to rapidly and safely exit an overhead cabin of the aircraft onto the main deck, while allowing cabin crew to safely ascend into the overhead cabin if need be. Hatch panels may blend in with overhead bin doors and ceiling panels of the main cabin; the inner portions of the hatch panels (facing the overhead cabin) may include anti-skid portions and graspable handles for descending passengers. The hatch may be easily activated by a passenger with a single motion (or remotely activated, or autodeployed). Once activated, the hatch panels may swing open and a telescoping ladder may deploy from the inner portion to the main deck, remaining rigid once reaching the floor. Similarly, any barriers protecting the ladder from passengers in the overhead cabin may be released, granting access to the telescoping ladder.

  • Patent number: 10824889
    Abstract: Passenger rest compartments may be incorporated into remote areas of an aircraft, either in the overhead crown region or in lower lobe cargo decks. Each passenger rest compartment includes two-way audio communication with the flight deck and non-intrusive non-visual monitoring of the compartments and surrounding environment to determine passenger presence, absence, and general well-being as well as environmental safety. Rest compartments may be integrated into rest cabins in the overhead or lower lobe areas, the rest cabins accessible from the main passenger cabin via an entry vestibule providing dedicated enclosed paths to the overhead and lower cabins. Additional deployable egress hatches may allow passengers to rapidly return to the main deck from the overhead and lower lobe cabins in the event of an emergency. Selected passenger seats (e.g., partitioned or other premium seats) may include private access to passenger rest compartments.

  • Publication number: 20200315756
    Abstract: An oral hygiene device is provided. The oral hygiene device includes a body having a base and first and second opposing sides extending from the base and defining a gap there between. The device may further include a plurality of corresponding notch pairs, wherein each corresponding notch pair has a first notch positioned in the first opposing side and a second notch positioned in the second opposing side. The location of the notch pairs may coincide with a user's mouth and in particular to the position of the user's teeth within the mouth. As such, a fibrous material, such as floss, may be coupled to the device such that the material spans the gap between at least one of the corresponding notch pairs so that the material may be inserted into the spaces between the user's teeth when the device is placed into the user's mouth.

  • Publication number: 20200255990
    Abstract: The field of the present invention relates, in general, to apparatus and methods of knitting a material into a tubular form, where the length of such tubular form is not dictated by conventional distances between the knitting areas and the catch basins of integrated machines. In short, this invention increases the distal relationship between the needle-equipped element, which performs the knitting function, and the basin that catches the resulting tubular form of the material. The basin rotates synchronized with the rotation of the resulting tubular form. The separation facilitates the continuous production of a length of the resulting tubular form of the material. The tubular form thus can be longer than such length where, as taught in the prior art, the catch basin is fixed—as part of integrated machines—in close proximity with the element that performs the knitting.
