Title: Echo canceller for video conferencing
Inventor: PARK JEONG-HOON
IPC: H04M1/20
Filed: 1997-10-24
Abstract: The echo controlling apparatus has memory 34 for storing a far-end input signal, a near-end input signal and an estimated echo signal as initial parameters matching the acoustic circumstances of a video conferencing system in a conference room. An echo controller 30 calculates an initial adaptive filter coefficient using the initial parameters stored in the memory, and updates the adaptive filter coefficient using new parameters input during a conference. A controller 32 reads the memory to provide the echo controller with the initial parameters. Therefore, parameters which match the circumstances of the video conferencing system of a conference room are stored in the memory in advance, and the initial adaptive filter coefficient is calculated using the parameters to control echoing. As a result, the echo control can be effectively performed from the initial stage of the video conference.

Title: Phase detection apparatus and method
Inventor: PATTERSON JEFFERY S
IPC: H03L7/089
Filed: 1998-07-20

Title: Optical detection of rotation of an electricity meter disk
Inventor: MACKIE DAVID
IPC: G01D5/347
Filed: 1999-05-13
Abstract: The periphery of an electricity meter disk is illuminated and an ordered sequence of pulses corresponding to the light reflected during one complete revolution is generated. In use, pulse sequences corresponding to reflected light are generated as the disk rotates and compared with this ordered sequence to determine the number of revolutions completed by the disk. The ordered sequence can be changed if variations from the expected pattern are detected in order to compensate for changes in, e.g., the position of the detector.

Patent GB-2352931-A (GB)
Title: Piezoelectric tag
Inventor: FORSTER IAN JAMES
IPC: G06K19/067
Filed: 1999-07-29
Abstract: A tag receives input radiation and generates therefrom a corresponding received signal which is applied to piezoelectric vibrating means 40 providing an increased voltage output to power an electronic circuit 60. The vibrating means may be a piezoelectric transformer, or a piezoelectric bi-morph, or a silicon micro-machined vibrating structure with driving means which stimulates series-connected piezoelectric transducers into vibration, the transducers being disposed in an evacuated housing. An interrogator may apply a 1GHz signal 100, amplitude modulated at 300KHz, to an antenna 20, the signal from antenna 20 being supplied to a rectifier/filter 30 which extracts the 300KHz signal to stimulate a piezoelectric transformer 40 into longitudinal vibration. The output of transformer 40 passes to a rectifier 50 providing a DC supply voltage to a transponder 60. The interrogator may also apply a 1.5GHz continuous wave signal to an antenna 64 of transponder 60 comprising a SAW delay line 68 and a reflection amplifier 70 with a switching oscillator which periodically switches the reflective gain of amplifier 70 between high and low gain states. A magnetostatic wave delay line (MWDL) may be used instead of a SAW device if signal 102 is in excess of 10GHz. A coil 310 may also be incorporated to form a resonant circuit with a capacitor C1 and transformer 40; in this case the tag can be powered either from the signal 100 received by antenna 20, or by inductively coupling a 300KHz magnetic field to coil 310. Alternative arrangements have a single antenna (Fig.6), a transmitter operating in Class C to transmit bursts of 500KHz at a burst repetition rate characteristic of the tag (Figs.4,6), or may be operable with a Manchester bi-phase encoded signal modulated onto the signal received by antenna (Fig.5). The tag may be in the form of a card (Fig.2) or a block. Uses of the tag include anti-theft tags, personal wearable ID tags, tags for marking out a path in a smoke filled burning building or for marking out a path for guidance of a robotic vehicle, environmental sensors, personal data loggers for hazardous working areas, or as an implanted device for dispensing insulin, for a heart pacemaker, or as an artificial retina.
