Abstract: According to an embodiment, a transducer package includes a circuit board including a port, a lid disposed over the port, an acoustic transducer disposed over the port and including a membrane, and an environmental transducer disposed at the circuit board in the port. The lid encloses a first region, and the membrane separates the port from the first region. Other embodiments include corresponding systems, apparatus, and structures, each configured to perform the actions or steps of corresponding embodiment methods.

Abstract: According to an embodiment, a method of sensing motion includes receiving a first signal from a first pressure sensor and a second signal from a second pressure sensor, comparing the first signal and the second signal, and characterizing a motion based on the comparing.

Abstract: A method and a system-on-a-chip for the guaranteed and energy-saving transmission of event messages is provided in a distributed computer system consisting of a plurality of node computers, which are interconnected by a time-controlled communications system. The node computers establish a common time base of known precision and periodically exchange messages at a prior defined points in time. A guaranteed event message is sent in a sporadic time-controlled message (SZN). The sporadic time-controlled message transports the guaranteed event message and is sent only if the content of this sporadic time-controlled message has been changed since the last time it was sent. The receiver stores the content of an incoming sporadic time-controlled message in a queue until the receiving process has read this content exactly once in a consuming manner.
