The present invention relates to a device for actuating a moving part (10) of a vehicle (1), particularly a trunk lid (10.1), a side door (10.2), or the like, without contact, comprising a first detection means (11) for detecting an object in a first detection area (11a) and a second detection means (12) for detecting an object in a second detection area (12a) so that the actuation of the moving part (10) can be activated through the detection means (11, 12). According to the invention, the first detection means (11) is designed as a first capacitance sensor (11), and the second detection means (12) is designed as a second capacitance sensor (12), wherein means (13, 14) are provided, with which the detection areas (11a, 12a) can be specified in areas separated from each other.

An intelligent door lock system includes components, a drive shaft of a lock device, a processor coupled to a wireless communication device, and an energy source coupled to a circuit. A device that converts energy into mechanical energy is coupled to the circuit and the drive shaft. The device that converts energy is coupled to the energy source to receive energy from the energy source. A ramp-up speed, a steady state speed and a ramp down speed are applied to the device that converts energy into mechanical energy. The ramp-up speed is applied when a first component initially engages with a second component. The steady state speed is applied following the initial engagement and is an operational speed that the device which converts energy uses during a standard operation mode. The ramp down speed is applied as the first and second components begin a state of non-engagement.

Methods, systems, and apparatus for door knock access control are disclosed. A monitoring system for monitoring a property includes: a proximity sensor located at a door of the property; a microphone that is configured to detect sound within an area near the door and generate audio data that represents the detected sound; and a monitor control unit configured to perform operations including: receiving, from the proximity sensor, proximity data indicating an object positioned within a set proximity to the door; based on receiving the proximity data, activating the microphone; receiving, from the microphone, the audio data; determining that a similarity between the audio data and stored audio data representing a knocking pattern satisfies similarity criteria; and in response to determining that the similarity between the audio data and the stored audio data satisfies similarity criteria, performing a monitoring system action.

Embodiments are directed to a step pad door lock system that processes the rhythm, pressure, and/or sequence of a user's steps on a pad. The step pad door lock system locks and unlocks doors based on the rhythm, pressure, and/or sequence of steps. If the rhythm, pressure, and/or sequence is the same as a user-defined predetermined rhythm, pressure, and/or sequence (acting as the password), the door unlocks.
