Abstract: A liquid immersion sensor for a mobile device with at least two acoustic transducers is described. The liquid immersion sensor may include a signal generator having a signal generator output configured to generate a signal for transmission via a first acoustic transducer, and a signal receiver having a signal receiver input configured to receive a delayed version of the generated signal via a second acoustic transducer. The signal receiver includes a signal receiver output. The liquid immersion sensor includes a controller having a first controller input for receiving a reference signal and a second controller input coupled to the signal receiver output. The controller determines a time lag value between the reference signal and the delayed signal and generates a control output signal dependent on the phase difference. The control output signal indicates if the mobile device is immersed in liquid.

Abstract: A controller for a haptic actuator is described. The controller includes a driver which has an output configured to be coupled to a linear resonant actuator in a first mode and a frequency detector having an input configured to be coupled to the haptic actuator in a second mode. The frequency detector is configured to detect a signal generated on the terminals of the haptic actuator in response to an externally applied force and to determine a resonant frequency of the haptic actuator from the generated signal.

Abstract: Flow sensors for measuring the flow of an ion-containing fluid may be implemented using mechanical or electrical techniques. Mechanical flow sensors are have moving parts and therefore may be unreliable after some time and are expensive to manufacture. Hall-effect type flow sensors typically require a reversible magnetic field to compensate for electrochemical effects. A flow meter including such a sensor uses an electromagnet. A flow sensor (100) is described using a capacitive sensor (10) and processor (12) to determine the flow rate from a change in capacitance and a magnetic field. Such a flow sensor may be implemented using CMOS technology. The flow sensor may operate in a magnetic field generated by a permanent magnet and measure the flow reliably.

Abstract: The invention provides MEMS oscillator designs in which the thermal actuation and piezoresistive detection signals are separated.A first approach splits the frequency of the loop into two distinct components, an actuation frequency and a detection frequency. A second approach modifies the design of the MEMS resonator such that the actuation signal follows a different path through the MEMS resonator than the detection signal.
