  • Patent number: 12369208
    Abstract: A mobile communication system that includes a short-range communication device, a mobile communication device, and a vehicle-based communication device configured to communicate with the short-range communication device. The system includes a sensor configured to generate sensor data and an electronic processor connected to the sensor and configured to receive sensor data that is associated with a scene external to a vehicle, detect an object based on the received sensor data, determine a parameter associated with the object based on the received sensor data and determine a communication interference value associated with the object based on the determined parameter. The electronic processor is also configured to pre-establish communication between the short-range communication device and the mobile communication device in response to determining that the communication interference value exceeds a pre-defined interference threshold.

  • Publication number: 20250162838
    Abstract: Techniques for automatically modifying elevator workflow based on incident type are provided. An incident occurring within an elevator is detected via a video camera. Video analytics are used to determine the incident type. It is determined that a floor selection associated with the incident type will place elevator passengers or people on the selected floor at risk. Elevator workflow execution is automatically modified based on the incident type and risk associated with the floor selection. The floor selection is displayed while modifying the elevator workflow to a different floor. A security notification indicative of the incident type and the automatic modification of the elevator workflow is sent.

  • Patent number: 7366275
    Abstract: An integrated circuit device having an output driver circuit and a control circuit. The output driver circuit outputs a first signal having a signal level according to a control value. The control circuit is coupled to receive the first signal from the output driver and adjusts the control value by a first increment until a transition event is detected. After the transition event is detected, the control circuit adjusts the control value by a second increment, the second increment being smaller than the first increment.
