  • Patent number: 10172526
    Abstract: The system and method of the present application includes a physiological sensor and a motion sensor connected to a patient. The physiological sensor detects patient connection to the sensor and collects a physiological signal while connected. When the physiological sensor is disconnected, the motion sensor data is analyzed. Patterns of sensor connection and patient movement typical for nurse initiated removal compared to accidental or patient initiated removals are created. The alarm protocol may be modified if the disconnection is due to patient movement. The detected movement patterns may include movement measurements that are close to the sensor that detects how the actual disconnection happens, or general movement information for the patient such as whether the patient has been still or has moved before the sensor gets disconnected. By using this information to classify the reason of the sensor removal, a more relevant alarm may be generated.

  • Patent number: 10177354
    Abstract: The present disclosure is directed to an energy storage device having improved thermal performance. More specifically, the energy storage device includes a housing with side walls that define an internal volume. The side walls include bottom and front side walls, with the front side wall having an air inlet and outlet configured to circulate cooling air therethrough. The energy storage device also includes a plurality of cells arranged in a matrix within the internal volume atop the bottom side wall. Further, the cells define a top surface. Further, the energy storage device includes an exhaust manifold adjacent to the front side wall between at least a portion of the cells and the air inlet. Thus, the exhaust manifold is configured to direct airflow from the top surface towards the bottom side wall and then to the air outlet so as to provide an airflow barrier between cooling air entering the air inlet and the cells.

  • Patent number: 10176386
    Abstract: A vehicle speed determination system and method receive image data of a field of view of a camera operably disposed onboard a vehicle. A speed and/or heading of the vehicle are determined as the vehicle is moving based at least in part on one or more differences in the image data. In one aspect, pixel intensities in different images or frames may be examined to identify one or more features of interest in the images or frames. Movement of the one or more features of interest in the images or frames is correlated to movement of the vehicle along the route, and the time difference between when the images or frames are obtained can be used to determine the vehicle speed.

  • Patent number: 10175003
    Abstract: A heat exchanger and a method for additively manufacturing the heat exchanger are provided. The heat exchanger includes a plurality of fluid passageways that are formed by additive manufacturing methods which enable the formation of fluid passageways that are smaller in size, that have thinner walls, and that have complex and intricate heat exchanger features that were not possible using prior manufacturing methods. For example, the fluid passageways may be curvilinear and may include heat exchanging fins that are less than 0.01 inches thick and formed at a fin density of more than four heat exchanging fins per centimeter. In addition, the heat exchanging fins may be angled with respect to the walls of the fluid passageways and adjacent fins may be offset relative to each other.

  • Patent number: 10174679
    Abstract: A method of controlling a startup sequence of a gas turbine. A turbine of the gas turbine may include a rotor that has a rotor velocity and a rotor acceleration during the startup sequence. The method may include the steps of: determining an originally scheduled startup duration for the gas turbine; measuring an intermediate rotor velocity at an intermediate time within the startup sequence; determining a recalculated remaining startup duration that is a duration calculated as necessary to achieve the final rotor velocity given the intermediate rotor velocity; determining a remaining portion of the originally scheduled startup duration based on the intermediate time; calculating a time multiplier based on a comparison of the recalculated remaining startup duration to the remaining portion of the originally scheduled startup duration; and scaling the rotor acceleration per the time multiplier for a duration until the final rotor velocity is achieved by the turbine.
