  • Publication number: 20230409627
    Abstract: A computing system that can receive an object search request from a user indicating a request to search for a specific object in an area traversed by one or more autonomous vehicle. The object search request can include a set of physical characteristics of the specific object. The computing system can then transmit a signal to an autonomous vehicle indicating a request for the autonomous vehicle to search for the specific object. The signal can cause the autonomous vehicle to transmit an image, selected based on a physical characteristic of the object, to the computing system. The computing system can then generate a score indicative of a difference between one or more physical characteristic of the object in the image and the specific object. The computing system can then selectively transmit the image to a mobile device operated by the user based on the score.

  • Patent number: 11243234
    Abstract: A monitor circuit for monitoring a level of a first and second regulated source may monitor a voltage level of regulated voltages or a current level of regulated currents. In an embodiment, the monitor circuit includes circuitry responsive to a first regulated current and to a second regulated current. A first circuit responsive to the first regulated current and to the second regulated current generates a first error signal indicative of at least one of an overcurrent condition of the first regulated current and an undercurrent condition of the second regulated current. A second circuit responsive to the first regulated current and to the second regulated current generates a second error signal indicative of at least one of an undercurrent condition of the first regulated current and an overcurrent condition of the second regulated current. A method for monitoring the levels of first and second regulated sources is also provided.

  • Patent number: 7921976
    Abstract: The invention relates to an overload protection device which has a force-loaded or torque-loaded component, a chamber for receiving a fluid which is at a predetermined pressure, and at least two transmitting elements which are connected to said component in a force-transmitting manner. The transmitting elements serve to transmit a counter-force or a counter-torque, which is generated by the pressure acting upon said transmitting elements, to the component, and is, at the same time, part of a sealing arrangement which occludes an outlet of the chamber due to the fluid pressure. If the force or torque acting upon the component are greater than the counter-force or counter-torque resulting from the predetermined pressure, the sealing arrangement unblocks the outlet, as a result of which the pressure in the chamber drops below said predetermined pressure.
