Abstract: A method and apparatus of access control as described. A touch of a touch zone of an access controller including a body area network (BAN) transceiver is detected. In response to detecting the touch, a request from an access controller comprising a BAN transceiver via a body area network is transmitted to a user of a portable device including a BAN transceiver and a biometric sensor. The request is received by the portable device via the BAN network. In response to receiving the request, the portable device transmits a digital key comprising biometric data detected by the biometric sensor and a digital identifier from the portable device to the access controller via the BAN network. The user is authenticated by the access controller using the digital key. The access controller controls and actuator to lock or unlock a door in response to the user being authenticated.

Abstract: A posture measurement apparatus and method is described. The posture measurement system includes a wearable sensor leader node comprising a UWB transceiver coupled to at least two antennas and one or more wearable sensor follower nodes each comprising a UWB transceiver coupled to one antenna. A first UWB signal is transmitted from the wearable sensor leader node to the one or more wearable follower sensor nodes. A second UWB signal is received by the wearable sensor leader node from each follower sensor node in response to receiving the first UWB signal. A time-of-flight value of a signal transmitted between the wearable leader sensor node and the wearable follower sensor node is determined from the first UWB signal and the second UWB signal. An angle of arrival value is determined from the second UWB signal. The body posture can be determined from the time-of-flight and angle-of-arrival value.

Abstract: The invention provides a clock select circuit and method which uses feedback arrangements between latches in different branches, with each branch for coupling an associated clock signal to the circuit output. An override circuit is provided in one of the feedback arrangements for preventing a latching delay in that feedback arrangement. This enables rapid switching between clocks in both directions.
