  • Patent number: 10591343
    Abstract: A fluid gauging system includes a set of fuel level probes and two computation modules adapted for inferring fluid level information based on measurement signals which originate from the probes. In a refuelling operation mode, the probes are distributed into two dynamically configurable subsets, which are separate and assigned respectively to the computation modules for deriving two results for the fluid level independently from each other. Such system has special interests for fuel tank equipment designed for aircraft. A major advantage is a reduction in the total number of fuel level probes which are necessary to obtain reliable results whatever the fuel level and the aircraft attitude and acceleration.

  • Patent number: 10573170
    Abstract: Technical solutions are described for controlling media playback based on consumption of contents in a cup. For example, an apparatus that controls the playback receives an amount of contents in the cup. The apparatus includes one or more sensors that keep track of amount of the contents and/or a rate of consumption of the contents. In an example, the apparatus transmits a signal to a media device in response to a predetermined threshold being greater than the rate of consumption of contents. In response, the media device may pause, stop, or play media. Additionally or alternatively, in response, the media device may display a user interface that describes a status of consumption of contents, such as the rate of flow.

    Abstract: The indication of a fuel level in a vehicle is disclosed herein. The vehicle can monitor the ignition switch to determine whether the vehicle is on or off. Also, the vehicle can determine a fuel level when state of the vehicle changes (e.g., switches from on to off, and vice versa). When the fuel level at the on state (e.g., ignition-on fuel level) is different from the fuel level at the off state, the vehicle can determine whether the vehicle is located at a fueling station. If the vehicle is located at the fueling station, the vehicle can generate an indication of the ignition-on fuel level within a user interface.

    Abstract: A method for assisting in maintenance of a motor vehicle having a drive motor, an drive energy storage device, and a filling level measuring device. A request for a maintenance process is identified by a self-monitoring device with the maintenance request being transmitted as a maintenance indication to a driver by an information device. The maintenance indication is transmitted to the driver as a function of a switch-off filling level present when the vehicle drive motor is switched off and detected by the filling level measuring device. The maintenance indication is transmitted when the switch-off filling level is lower than a preset filling level threshold value or when a filling level difference between a switch-on filling level, present when the vehicle drive motor is subsequently switched on again and detected by the filling level measuring device, and the preceding switch-off filling level indicates a positive filling level value.

  • Publication number: 20150019146
    Abstract: A method and a system for monitoring the performance of combined sewer overflow structures is described. The inventive system includes sensors for monitoring the level of sewage in the structure and the operation of valves. A data processing unit collects data and calculates the flow of an overflow event and/or the performance of gate valves. The system may be battery operated and may adaptively change the sensor sampling time to prolong battery lifetime.

  • Patent number: 8930144
    Abstract: An apparatus as provided for measuring acceleration of a person's head or other object. The apparatus comprises a sensor for sensing acceleration and a controller for controlling recording of data resulting from the sensed acceleration due to an explosive force. The controller is adapted to determine whether or not to enable recording of the data based on the sensed acceleration. A data receiver is provided to receive the sensed acceleration data from the sensing means, and requires electrical power to enable data to be received thereby. The controller controls electrical power to the receiver so that if the sensed acceleration reaches or exceeds a predetermined value, electrical power to the data receiver is enabled. The recorded acceleration data may be used for injury analysis.

  • Patent number: 8924167
    Abstract: A dual sensor sediment monitoring system for stormwater management facilities includes a capacitive sensor and an ultrasonic sensor. The former periodically determines if a liquid layer exists above the sediment and activates the ultrasonic sensor when it does not. The echo delay measured by the ultrasonic sensor is used to calculate the sediment level, which is wirelessly transmitted to a remote computer for database compilation and use in scheduling maintenance involving sediment removal.

  • Publication number: 20140365043
    Abstract: An amount of propellant remaining in an orbiting satellite can be estimated in a more accurate manner than is possible with conventional approached. Pressure and temperature telemetry data received from the satellite can be analyzed using a maximum likelihood estimation approach that reconstructs a predicted tank pressure signal using the temperature data and determines a pressurant volume necessary to make the reconstructed pressure signal match the received pressure signal. Drift of the pressure data received from pressure transducers in the satellite can also be addressed using the current subject matter, as can issues including but not limited to inaccessible propellant due to satellite spin, tank expansion under pressure, and the like. Independent determinations of the amounts of propellant remaining can be made using moment of inertia calculations in situations in which an axis of spin of the satellite is known a priori.

  • Patent number: 8892373
    Abstract: A method for determining the starting instant (t0) of a periodically oscillating signal response (E2; E2?), wherein the signal response comprises a first set of half periods (E2a-d; E2?a-d) having a polarity equal to a polarity of the first half period (E2a; E2?a) in the signal response, and a second set of half periods (E2e-h; E2?e-h) having a polarity opposite to the polarity of the first half period (E2a; E2?a) in the signal response. The method comprises the steps of: determining a peak half period (E2e; E2?f) as the half period with the highest amplitude in a selected one of the first and second sets; determining a zero-crossing instant (ZC1; ZC?1) of the signal response occurring a known time distance from the peak half period (E2e; E2?f); determining the starting instant (t0) of the signal response (E2; E2?) based on the zero-crossing instant (ZC1; ZC?1) and a relationship between the peak half period (E2e; E2?f) and the starting instant (t0).
