  • Patent number: 11959758
    Abstract: The disclosure is generally directed to systems and methods for optimizing vehicle deployment. A software application is used to obtain information about a travel route. The information is used to evaluate an energy storage depletion characteristic of a battery that is used to operate a battery-operated vehicle and to determine whether the battery-operated vehicle can be deployed on the travel route. One of the factors that can affect the energy storage depletion characteristic of the battery is ambient temperature, because battery performance may be adversely affected by extreme temperatures. Consequently, a range of operation of the battery-operated vehicle may be impacted if the travel route has extreme ambient temperatures. If the evaluation indicates that the energy storage depletion characteristic of the battery is unsuitable for the travel route, another battery-operated vehicle with a better battery may be deployed on the travel route.

  • Patent number: 11787294
    Abstract: An autonomous mobile device (AMD) operating in a first mode moves within a physical space to perform various tasks such as displaying information on a screen, following a user, and so forth. The first mode may involve the AMD moving or maintaining a particular pose. While the AMD is in the first mode, a user may apply an external force to the AMD to reposition the AMD to a desired pose. Application of this external force on the AMD is detected and results in the AMD transitioning to a second mode in which the AMD may be repositioned. While in the second mode, the user may reposition the AMD. The second mode may constrain the magnitude of the resulting movement, preventing the user from moving the AMD too quickly which could damage components within the AMD. Once the external force ceases, the AMD may transition back to the first mode.

  • Patent number: 11378035
    Abstract: An engine control device includes a processor configured to execute a fuel injection control including: a first fuel injection processing for injecting an amount of fuel according to a first intake air amount based on an intake air flow rate detected by an air flow sensor; and a second fuel injection processing for injecting an amount of fuel according to a second intake air amount based on a throttle opening degree detected by a throttle position sensor. The processor selects the first fuel injection processing when a pulsation rate of the intake air flow rate is equal to or lower than a pulsation rate threshold value, and selects the second fuel injection processing when the pulsation rate is higher than the pulsation rate threshold value. The pulsation rate threshold value is smaller when a temperature correlation value is low than when the temperature correlation value is high.

  • Patent number: 11203242
    Abstract: A vehicle incorporates a gravity-assist energy harvesting suspension system including one or more gravitational positive displacement pumps. The positive displacement pump has a cylinder and a reciprocating piston inside the cylinder. The piston is adapted for movement along a compression stroke and an opposite extension stroke in response to a gravitational bounce of the vehicle when in motion. A turbine comprising a rotor shaft and attached blades is mounted relative to a distal end of a fluid outlet hose connected to the pump. Fluid discharged through the outlet hose acts on the blades, thereby moving and imparting rotational energy to the rotor shaft. A generator is operatively connected to the turbine, and is adapted for converting the rotational energy generated by the rotor shaft to electrical energy.

  • Patent number: 11198352
    Abstract: A relay (25) connects and disconnects an electrical circuit to which an inverter (16) and an electricity storage device (19) are connected. A BCU (22) controls the electricity storage device (19). An HC (27) controls an electric motor (15), the inverter (16) and the BCU (22). The HC (27) and the BCU (22) respectively have FET switches (30, 31) for controlling supply and stop of the excitation current in the relay (25). When the electricity storage device (19) is determined to be in an abnormal state, the BCU (22) transmits an abnormal signal to the HC (27), and when a predetermined time has elapsed, turns off (opens) the first FET switch (30) of the BCU (22). The HC (27) executes stop processing based upon the abnormal signal received from the BCU (22) and then turns off (opens) the second FET switch (31) of the HC (27).
