  • Patent number: 11617846
    Abstract: A multi-night titration (MNT) process to find an optimal single therapeutic pressure of a CPAP device. This single therapeutic pressure can then be used on an on-going basis by the patient after the titration period. The MNT process differs from current auto adjusting processes used for titration (or ongoing use) in that the MNT process does not respond locally by adjusting pressures to individual events. With existing devices, the continuous adjustment of supplied air pressure always responds to one or a small number of events and thus fails to compensate for a patient's adaptation thereto, resulting in the supply of a less than optimal therapeutic pressure to the patient. While auto adjusting processes often capture and respond well to short-term and transient conditions, the MNT process of the current disclosure seeks to capture long term trends and find the most suitable average single pressure for a patient.

  • Patent number: 11620523
    Abstract: Artificial-intelligence-based river information system. In an embodiment, a first training dataset is used to train a travel time prediction model to predict a travel time along the waterway for a given trip. In addition, a second training dataset is used to train a river level prediction model to predict a river level along the waterway for a given time. For each of a plurality of trips, a request is received that specifies the trip and a time of the trip, and, in response to the request, the travel time prediction model is used to predict a travel time for the trip, and the river level prediction model is used to predict a river level of the waterway at one or more points along the trip. Then, a voyage plan is generated based on one or both of the predicted travel time and the predicted river level.

  • Patent number: 11619295
    Abstract: A bypass apparatus for lubricant in an unregulated pressurized gearbox including: a block including a lubricant inlet in fluid communication with a pressure relief valve, wherein the pressure relief valve diverts lubricant into the gearbox or into an oil filter, wherein lubricant is returned to the gearbox when the lubricant is cold and/or pressure at the pressure relief valve is high to reduce damage to the gearbox caused by high pressure during a cold start, and when the lubricant temperature increases and the pressure is reduced the pressure relief valve closes and lubricant enters the oil filter.

  • Patent number: 11619759
    Abstract: An antenna arrangement. The arrangement uses four conductive loops, each within a distinct plane from the other conductive loops. The four conductive loops have a common center point. Each loop is within a dipole magnetic field, and detects a component thereof. By balancing the signals received between matched pairs of the conductive loops, the difference between the signals can be used to guide the antenna arrangement to a null point—that is—a point in the magnetic field where each pair of conductive loops is balanced. The antenna arrangement can further be used to determine the depth of the dipole field source using the magnitude of the field.

  • Patent number: 11621532
    Abstract: A method of manipulating a wire, having an electrical contact, comprises clamping the wire with a predetermined force between a first gripping portion, installed in a first channel of a first tip half, and a second gripping portion, installed in a second channel of a second tip half. The method also includes pushing the electrical contact into a receptacle of a terminal block using a first internal shoulder of the first channel and a second internal shoulder of the second channel to interlock the electrical contact and the terminal block. With the wire clamped between the first gripping portion and the second gripping portion, the method includes verifying that the electrical contact and the terminal block are interlocked by pulling the first tip half and the second tip half away from the terminal block until the wire slips along the first gripping portion and the second gripping portion.

  • Publication number: 20230097459
    Abstract: Systems and methods are disclosed herein for computer-aided method for developing, customizing, and faciliating the process of dispute, debates and discussions between individuals and groups. The mobile application, computer software, addons to instant messaging and online conference platforms create mental confrontation routines (e.g., dispute, debate or discussion), where opposing sides can formulate their position and support it with arguments or counter-arguments. All arguments and counter-arguments take the form of time-limited video clips, thus creating a personal component, showing the emotional state of parties, body language, facial expression—all that creates a feeling of realistic argument, yet in a structured step-by-step format. The weight of each side’s arguments is assessed by judges (one or more) who choose the winner and administer justice.
