  This paper presents a novel hybrid CMOS/MEMS tilt sensor with a 5∘ resolution over a 300∘ range. The device uses a MEMS-based semicircular mass suspended from a rigid body, projecting a shadow onto the CMOS-based optical sensor surface. A one-dimensional photodiode array arranged as a uniformly segmented ring is then used to determine the tilt angle by detecting the position of the semicircular mass. The complete sensor occupies an area of under 2.5 mm × 2.5 mm.

  Wireless Data Transmission Method and Apparatus

  , US2007291834 (A1); GB20040010693 20040513; WO2005GB50061 20050506

  An ultra-wideband wireless information transmission method comprising transmitting electromagnetic data pulses and reference pulses over the transmission medium, information being encoded as a time shift between the data pulses and the reference pulses, at least two of the data pulses sharing a common reference pulse, and receiving the data and reference pulses and using the associated timing information to recover said information.

  Implantable Surface Acoustic Wave Devices for Long Term Clinical Monitoring

  , US2007282172(A1); GB20030029019 20031215; WO2004GB05228 20041214

  A surface or bulk acoustic wave device can be implanted in or worn on a human or animal body to monitor various parameters thereof. The device comprises a pair of interdigitated transducers spaced apart over the surface of a piezo-electric sub-strate that is exposed to the parameter to be monitored. The device is interrogated by a radio-frequency signal being supplied to one of the transducers and detected after reflection by the other transducer. The parameter is measured by comparison of the supplied and received signals.

  A novel architecture for running cross-correlation and convolution using bitstream processing is proposed. The computationally intensive multiplications inherent in cross-correlation and convolution are replaced by simple logic operations (AND XOR) using bitstream representation. The reduced complexity enables compact and energy efficient silicon solutions suitable for small, portable devices such as wearable heartbeat detecting electronics embedded in the actual ECG patch.

  Audio Signal Processors

  , US2007282171(A1); GB19980000585 19980112 ; GB19980016351 19980727; WO1999GB00055 19990108

  An audio signal processor includes a tone control ( 23 ). The tone control comprises two low-pass filters ( 221, 222 ) operating in current-mode and a subtractor ( 223 ) which subtracts the output currents of the filters to produce a band-pass characteristic. Each filter is a tuneable log-domain current-mode filter comprising MOS transistors operating in weak inversion. The tone control is useful in audio signal processors, hearing aids and single-channel and multi-channel Cochlear implants...
