Title: Diversity antenna system
Inventor: BRENNAN PAUL VICTOR
IPC: H04B7/08
Filed: 1991-07-12
Abstract: A diversity antenna system is described which combines the signals (21, 22, etc.) of a number of antenna elements (1, 2, etc.) - that may have different positions and/or polarisations and/or radiation patterns - with weightings dependent on their respective signal levels. The combination process is performed at baseband, after demodulation, by means of a separate receiver (31, 32, etc.) and variable-gain amplifier (51, 52, etc.) for each antenna element. The gain setting of each variable-gain amplifier is adjusted in proportion to the signal level present at each receiver (31, 32, etc.) by the use of an open-loop control technique which responds swiftly and accurately to changes in signal level in order to counter the effects of signal fading due, for example, to multipath fading. <IMAGE>

Title: Improvements relating to apparatus for use in producing non-woven webs from thermo-plastic
Inventor: SLACK IAN DAVID
IPC: D01G25/00
Filed: 1991-07-23
Abstract: The present specification discloses a method and apparatus for use in producing non-woven webs from thermo-plastic polymer materials. The apparatus comprises a chamber (11) through which a movable conveyor (13) extends, the chamber (11) being connected to evacuation means (23) which can create a partial vacuum in chamber (11). A tapered duct (17) connects with chamber (11) above conveyor (13) and extends generally vertically upwardly from a position beneath a spinnerette (31). The upper end of duct (27) is open to the atmosphere and has a larger cross- sectional throughflow area than the lower end region thereof, which communicates with chamber (11). Thus evacuation means (23) in effect draws air into duct (27) so that the filaments produced by spinnerette (31) are entrained in the air flow and accelerated by the air flow along tapered duct (27). On entering the chamber (11) the air flow velocity reduces but the momentum of the filaments causes them to disperse randomly and be collected on conveyor (13). The non-woven web is subjected to heat bonding, calendering or needling process. <IMAGE>

Title: High frequency voltage/current-measuring circuit
Inventor: DOBLE RICHARD GEORGE VIVIAN
IPC: G01R19/03
Filed: 1990-08-20
Abstract: A circuit for measuring the R.M.S. voltage of a high frequency signal VAC (e.g. 100MHz) comprises two series- connected ntc thermistors (TH1, TH2) in a bridge circuit which is energised by a current source (1). The unknown signal is applied across one (TH1) of the thermistors and the resulting change in the resistance causes a D.C. output voltage to appear across the balanced terminals (T3, T4) of the bridge. This output voltage is proportional to the square of the R.M.S. voltage of the A.C. signal. In another embodiment (Figure 4) two ptc thermistors are connected in parallel in a bridge circuit which is energised by a voltage source, and are used to measure R.M.S. current. In each case, the thermistors are preferably operated in a negative slope resistance portion of their voltage-current characteristic. In a further embodiment (Figure 6 not shown) two balanced bridges, each incorporating two thermistors, are connected in series in one arm of a bridge circuit, and a compensating signal is applied by a feedback circuit to one bridge so as to match the heating effect of the unknown A.C. signal applied to the other bridge. In Figure 5 (not shown) a second bridge is used to vary the current supply to a first measuring bridge whereby to counteract ambient fluctuations. <IMAGE>

Title: Reducing thermal stress in I.C. chip mountings
Inventor: WILLIAMS RONALD L
IPC: H01L23/544
Filed: 1993-12-07
Abstract: An integrated circuit (IC) formed in a semiconductor layer 14 is flip-chip bonded to a printed wiring board 26 (PWB), despite the PWB having a substantial temperature coefficient of expansion (TCE) mismatch with the semiconductor material. The thin semiconductor layer 14 is adhered to a much thicker chip substrate 20 with a ICE that is more closely matched with the ICE of the PWB. Through a proper selection of dimensions, the IC layer 14 will substantially assume the ICE of the chip substrate, and thus avoid excessive stresses in the flip-chip bonds during large temperature excursions. Starting with a conventional IC wafer having a semiconductor substrate, the semiconductor substrate is removed and replaced with a new chip substrate 20, which may be formed from the same material as the PWB. When the initial wafer is provided with a thin insulative layer 12 between the IC layer and semiconductor substrate, the insulative layer is used as an etch stop for removal of the semiconductor substrate. <IMAGE>
