Inventor: RICHARDSON CHRISTOPHER KEITH
IPC: G06K19/07
Filed: 1995-10-10
Abstract: An electronic tag comprising an antenna 2, 3 and a field effect transistor (FET) 5, which is connected to the antenna so that it operates to vary the efficiency with which the antenna receives a first received radio frequency signal at a frequency of f 1 , in dependence upon a second received radio frequency signal at a frequency of f 2 , whereby the first and second radio frequency signals are mixed so that re-radiated radio frequency signals are produced having frequencies of f 1 Ò f 2 . The frequency f 1 is received by the dipole 2, 3 and the resistence between the arms 2, 3 is varied by the second frequency signal f 2 received by the resonant antenna formed by conductor 8 connected to the FET gate 7. The electronic tag has the advantage that it requires no local power source for its operation. A detector suitable for detecting the reradiated signal, and for determining a direction from which it originates may thus be used to locate a lost or stolen article which embodies the tag.

Abstract: The invention is an in-line torque meter for use with an absorption dynamometer (10) in which the twist of a rotating shaft (70) that transmits torque from an engine to an air dynamometer is measured by a single sensor (64) on the adjacent stationary structure. The torque shaft (70) is supported at the dynamometer end by a splined attachment to the shaft (16) of the dynamometer (10) and at the engine end in a pan of preloaded angular contact ball bearings (74). Torque from the engine causes the shaft to twist. Attached to and rotating with the shaft (70) are two sleeves (66, 68) with projecting teeth (67, 69), one sleeve attached at each end of the torque shaft. The projecting teeth (67, 69) are interleaved and are located so that both sets of teeth can be sensed by an adjacent single sensor (64). When the shaft is twisted by the applied torque, the teeth on the two sleeves are angularly displaced with respect to each other. This angular displacement is measured as a phases shift in the signal generated by the sensor (64). The phases shift being directly proportional to the applied torque. <IMAGE>

Title: HTTP Caching Proxy, to Filter and Control Display of Data in a Web Browser
Inventor: BERANEK MICHAEL
IPC: H04N21/40
Filed: 1998-07-29
Abstract: A method of controlling how a Web document is presented for display on a browser of a client machine. The Web document typically is formatted according to a markup language such as HTML. The method uses a client side HTTP caching proxy to intercept the Web document and then dynamically rewrite the document before it is displayed on the browser. In particular, as the Web document is received from the server, the HTML is parsed to identify the format of the document and the information therein. A filter mechanism is then used to reformat the Web document according to some given protocol, and the re-formatted Web document is then passed to the browser for display. Dynamic alteration of the HTML in this manner enables control of the "look and feel" of the browser display.

Title: Gearlever and controller with automatic switching between manual and automatic modes
Inventor: DUNCAN BRUCE
IPC: B60K20/04
Filed: 1999-08-19
Abstract: A lever arrangement 1, for a off road vehicle, includes a functional lever 3, eg a joy stick or slider, which is transiently displaced to manually select a shift in transmission combination/ratio which is sustained until a controller determines that an alternative ratio is required in order to provide best performance or mode of operation, eg hill ascent/descent. Thus driver selection of a particular transmission ratio is over-ridden and failure to de-select that ratio does not inhibit on-going vehicle operation to provide best performance determine by the controller. A display area 4 in which current vehicle operating functions are depicted, for example a transmission window 5 shows gear ratio or drive condition whilst a mode window displays a mode of vehicle operation required by the driver selected by a mode switch 7. Vehicle operating modes are selected by operational lever 2 which has operational positions which relate to automatic gearbox combinations, eg park, reverse, drive. The lever 3 may select two/four wheel drive, front/rear wheel drive, side to side wheel drive and/or high/low gear ranges.
