Abstract: An ultrasound system has a set of CMUT transducer devices and drive electronics for operating a selected device of the set. The drive electronics is shared between all devices of the set. Selection is made by using a set of switches (178), with a respective switch between a DC bias output (166) of the drive electronics and an associated input (160) of each device. This provides a simple way to provide a selection function between the drive electronics and multiple ultrasound devices. In this way, the number of devices may be scale up, to cover a larger area, but without scaling the cost of the system by the same degree.

The wireless device may then transmit the acknowledgment for the received transport block.

Abstract: Described herein are methods, devices and systems for predicting ventilator associated pneumonia (VAP). In an example, data of a patient including one or more features useful in predicting VAPs are accessed and the features are extracted. A model is activated based on a time parameter associated with mechanical ventilation or length of stay in ICU. The extracted features are evaluated automatically by the activated model to determine a probability that a VAP will occur. If it is determined, based on the evaluating, that a VAP has a probability of occurring that exceeds a threshold, an indication that the VAP is predicted to occur may be provided. Other examples are disclosed and claimed.

Abstract: A power transmitter (101) of a wireless power transfer system comprises a resonance including a transmitter coil (103) for generating a power transfer signal for wirelessly transferring power to a power receiver (105).

Further, the power transmitter (101) comprises an adapter (1309) which adapts the maximum limit in response to a load indication indicative of a loading of the power transfer signal by the power receiver (105).

Abstract: An ultrasound transducer unit (12), e.g. probe, is configured with a friction guiding function. The transducer unit (12) comprises a vibration generating means (20) at a tissue contact area, and has means for sensing a sliding direction of the transducer unit across a tissue surface (42) at which the contact area is incident.
