Title: Luggage trolley
Inventor: BASHARAT ABDUL MAJID
IPC: B62B3/14
Filed: 1994-07-28
Abstract: The trolley comprises a base chassis 52 and an upright support structure 54 fixed to and projecting upwardly from a rear portion of the base chassis, and surmounted by a push-handle assembly (94, figure 9). An upwardly open supplementary luggage receptacle 90 is mounted on the rear side of the upright structure to permit the receptacle to be made larger without obstructing the main luggage-carrying capacity of the platform 56. The rear wheel castors 68 are offset rearwardly relative to the back end of the platform 56 to improve stability. The platform 56 is forwardly inclined for ease of stacking and generally lowered for stability and convenience of loading by a rearwardly inclined interconnecting portion 82 of the chassis between the rear end of the platform 56 and the base end of the upright support structure. The handle assembly, which is applicable to many different kinds of trolley, has a centre cross-bar 110 spaced rearwardly of the support structure 54 and two side portions 112 projecting upwardly and forwardly from opposite ends of the cross-bar portion to provide for a comfortable double "pistol-grip" holding action by the user. <IMAGE>

Title: Audio intrusion detection system
Inventor: RICKMAN STEPHEN A
IPC: G08B29/14
Filed: 1992-05-01
Abstract: A supervisory circuit 10 for use with an audio intrusion detection system 30 peridically generates an audio test signal which is supplied to a sounder 12 which emits an audio test sound. The audio test sound is directed into a volume of space, in the same volume of space as which the audio intrusion detection system is directed to detect. The audio intrusion detection system detects the test sound and generates an audio test signal in response thereto. During the generation of the audio test sound, the comparing means 42 of the audio intrusion detection system 30 is disabled. The audio test signal generated by the supervisory circuit 10 is then compared 22 to a test threshold signal. A test result signal is generated in response to the comparison with the test result signal indicative of the operability of the audio intrusion detection system 30. In intrusion detection, a microphone 32 and a 3 to 30 Hz bandpass filter 36 detect pressure waves, and the microphone and a 7 kHz bandpass filter 34 detect audio waves. <IMAGE>

Title: Budget reminder calculator
Inventor: MAK RONNIE CHI WAH
IPC: G06Q30/00
Filed: 1995-06-02
Abstract: A budget reminder calculator conveniently carried in a wallet or handbag, including a memory for storing an expenditure budget value and an alert value. The user sets the budget value to a desired level of expenditure for a given period of time, and the alert value at a suitable threshold for warning that the budget is depleted to a given value. The user enters each item of expenditure made and the calculator automatically maintains a cumulative sum, or budget amount remaining, providing audible or visual warning of both reaching the alert value and reaching the budget value. Financial expenditure via a number of media such as cash, cheque, credit and debit card is thereby readily monitored, and impending overspend alerted to the user. The calculator may also provide a currency exchange facility of benefit to maintain a budget where expenditure may be in a number of different currencies, for example when travelling on business or holiday.

Patent GB-2324680-A (GB)
Title: Locating a radio communication unit
Inventor: WYRWAS RICHARD
IPC: H04Q7/34
Filed: 1997-04-26
Abstract: In a satellite communications system, each satellite provides an array of overlapping spot beams 30A-G on the surface of the earth, the position of each spot beam being known at any instant. On the earth, a terminal listens to all audible spot beams and determines which ones provide signals above a predetermined level. By mapping which spot beams are audible above the limit, it can rapidly be determined which zone 58A-M the terminal occupies and thus the position of the terminal on the earth, eg if signals from spot beams 30E and 30G are the only ones determined to be above the threshold then the terminal must be in zone 58H.

Title: Field effect transistor
Inventor: ASHLEY TIMOTHY
IPC: H01L29/205
Filed: 1997-11-28
Abstract: A field effect transistor (FET) is of the type which employs base biasing to depress the intrinsic contribution to conduction and reduce leakage current. It incorporates four successive layers (102 to 108): a p<SP>+</SP> InSb base layer (102), a p<SP>+</SP> InAlSb barrier layer (104), a n intrinsic layer (106) and an insulating SiO 2  layer (108); p<SP>+</SP> source and drain regions (110, 112) are implanted in the intrinsic layer (106). The FET is an enhancement mode MISFET (100) in which biasing establishes the FET channel in the intrinsic layer (106). The insulating layer (108) has a substantially flat surface supporting a gate contact (116). This avoids or reduces departures from channel straightness caused by intrusion of a gate groove, and enables a high value of current gain cut-off frequency to be obtained. In FETs with layers that are not flat, departures from channel straightness should not be more than 50 nm in extent, preferably less than 5 nm.
