Title: Adaptive antenna array and method of controlling operation thereof
Inventor: OWEN RAYMOND
IPC: H01Q3/26
Filed: 2000-06-07
Abstract: An adaptive antenna array 14 includes a plurality of antenna elements 12a-12k, 48a-48k responsive to uplink communications 16a-16k and arranged to support directional-orientated downlink communication to subscriber units 18. The adaptive antenna array 14 is operationally responsive to a signal processor 28 co-operates with direction of arrival estimation logic 36 to assess an angle of arrival of uplink communications incident to the array. To avoid inter-cell interference, especially during early stages of a call, the signal processor operates to ensure that a wide area downlink beam (fig. 4 108) is provided for a downlink path to an addressed subscriber unit. With time and/or with reported downlink quality of service metrics, the signal processor 28 regulates a width of the downlink beam by altering the number of antenna elements used to support the downlink beam, thereby altering the downlink beam aperture. Generally, with time, more antenna elements are used and so the beam is narrowed, although in-call fluctuations in downlink quality of service are dynamically addressed by the signal processor 28 by either narrowing or broadening the width of the downlink beam by respectively switching antenna elements 12a-12k, 48a-48k into or out of the adaptive antenna array 14.

Title: Power modulated optical overhead signals
Inventor: DRISCOLL JOHN PATRICK
IPC: H04B10/08
Filed: 1999-03-12
Abstract: A signal transmission system uses an optical signal for carrying traffic information by modulating the brightness of the optical signal at a high frequency. A lower frequency optical overhead signal also modulates the optical signal. The optical overhead signal modulates the maximum brightness of the signal, but not its minimum brightness so that the signal can be recovered even if the system is AC coupled.

Title: Test Circuit
Inventor: CORR WILLIAM ERIC
IPC: G01R19/165
Filed: 2001-03-14
Abstract: A test circuit 100 and method for measuring power supply integrity is provided. The circuit may be incorporated on-chip and is small enough to be integrated many times across the surface of the die (fig 4) for measuring integrity parameters at several locations on the chip. The circuit instantaneously measures, e.g., the rail voltage of a power supply, which may be fluctuating at the time of measurement. In addition, the circuit isolates itself from all chip power rails, 170, 175 for the duration of the measurement, thereby eliminating any influence of external noise on the measurement. A storage capacitor 140 is charged up to full power rail voltage for powering up a comparator 130. Then, the comparator is isolated from the power rails and the measurements are taken. Based upon the measurements, certain power supply integrity parameters are quantified including ground bounce and power droop.

Title: PIN photodiode with intrinsic region implanted with deep band gap levels
Inventor: KNIGHTS ANDREW PETER
IPC: H01L31/028
Filed: 2001-12-27
Abstract: A photodiode comprises p-i-n diode having intrinsic region (5) between p- and n-doped regions (6,7) formed on semiconductor substrate (2), which may be a silicon-on-insulator chip (1,3). The intrinsic region (5) is modified to introduce deep band gap levels (11) thus enabling absorption of incident radiation at a longer wavelength and lower energy than the band gap. This enables an electrical signal to be generated across the p-i-n diode at this longer wavelength, resulting in a current in circuit (10). The intrinsic region (5) may be modified by ion implantation to introduce defects such as elemental impurities, and may form part of a rib waveguide structure (4). The wavelength band absorbed by the deep band gap levels may range from 1.3 to 1.5 microns, with the band gap corresponding to radiation of 0.6 to 0.8 microns.

IPC: A61B5/11
Filed: 2002-01-29
Abstract: A device 1 for monitoring contractions of the uterus has a two-part housing 2, 3, a diaphragm 12 attached to the housing and strain gauges 17, 18 mounted on the diaphragm 12. The device is placed in skin contact with a patient's abdomen and a contraction causes a distortion of the diaphragm 12. The strain gauges 17, 18 produce an output signal corresponding to the strain produced in the diaphragm. A processor (53, figure 5) generates a monitoring signal for display and storage. A contact member 11 is used to transfer force from the abdomen to the diaphragm 12 via an aperture 7 in the housing, and the diaphragm may include slits to increase flexibility. A venting conduit is provided via a cable 24 leading to an external monitoring device (53, 54, 55 figure 5) to release pressure within the housing. The device is airtight due to the provision of covering membrane 23, and so is suitable for underwater use.
