| 20090092240 | Audio Conferencing - A communications conference management system is prepared for the establishment of conference calls, by pre-programming the management system with identification data for participants authorised to be connected to a specific conference residing on a conference bridge. The conference management system is arranged such that connection to a specific conference residing on a bridge can be made in response to recognition of the network identifier. | 04-09-2009 |
| 20090094547 | Audio conferencing announcements - An audio conferencing facility has a database for storing user data relating to authorisation to use the facility, and provides storage for a name file to be stored as part of the user data, which may be retrieved for generation of an audio signal to be played to one or more of the participants to a communication connection whenever that participant uses the conferencing facility. The name may be generated as an audio recording by the user, or entered as text, or retrieved from a directory in text form. It may be stored either in audio form or as text, for conversion to audio using a speech synthesiser. | 04-09-2009 |

| 20090002528 | HIGH DYNAMIC RANGE SENSOR WITH BLOOMING DRAIN - An image sensor has at least two photodiodes in each unit pixel. A high dynamic range is achieved by selecting different exposure times for the photodiodes. Additionally, blooming is reduced. The readout timing cycle is chosen so that the short exposure time photodiodes act as drains for excess charge overflowing from the long exposure time photodiodes. To improve draining of excess charge, the arrangement of photodiodes may be further selected so that long exposure time photodiodes are neighbored along vertical and horizontal directions by short exposure time photodiodes. A micro-lens array may also be provided in which light is preferentially coupled to the long exposure time photodiodes to improve sensitivity. | 01-01-2009 |

| 20090111394 | MONOLITHIC INTEGRATED TRANSCEIVER - A variable operational mode transceiver device formed with an integrated circuit having a semiconductor material substrate supporting a feedback oscillator having a signal power divider electrically coupled to said feedback oscillator output, and a signal frequency multiplier electrically coupled to said signal power divider. A signal mixer has a pair of inputs of which one is electrically coupled to that remaining one of said pair of outputs of said signal power divider. | 04-30-2009 |
| 20110166629 | MEASURING ANTENNA MATCHING VIA TRANSMITTER CURRENT DRAW - This document discusses, among other things, an implantable telemetry system including an RF transceiver configured to drive an antenna and a matching circuit, configured to be coupled to the antenna, the matching circuit including a control parameter configured to adjust the impedance of the matching circuit. The implantable telemetry system also includes a control circuit configured to receive an indication of the RF transceiver current draw and to control the control parameter of the matching circuit using the received indication of current draw. In an example, the control parameter is controlled to decrease the RF transceiver current draw. | 07-07-2011 |
