Title: Space coordinate detecting device and input apparatus
Inventor: MORISHITA ICHIRO
IPC: G06F3/042
Filed: 1995-05-23
Abstract: A space coordinate detecting device has a light emitting section 10 and a detecting section 12 for determining the relative angle between the emitting and detecting sections and hence providing coordinates to an input apparatus eg to control a cursor on a screen. The detecting section has four light sensors 23 for detecting movent in two dimensions. Two light sources 16 and 17 in the light emitting section emit distinguishable eg modulated light which is formed into separate square light spots on the sensors 23 by an aperture 22a. By calculating a difference in the detected output among the sensors, it is possible to determine the centre of each light spot. The relative rotational angle of the light emitting and detecting sections about the Z axis can be determined by calculating an inclination angle on X-Y orthogonal coordinates of a line x connecting the centres of both light spots. <IMAGE>

Title: Switched electrical socket outlet
Inventor: JONES JONATHAN
IPC: H01R13/707
Filed: 1995-08-16
Abstract: An interlocked socket outlet includes: an isolator in a housing 3 turned ON and OFF by a knob 35, 36; a socket 50 for receiving a plug 60; and, between the knob and the socket, an interlock link which prevents the plug from being removed when the isolator is ON. The interlock may have gears driven by the knob spindle through a square hole 39. The gears move a locking member 51 which engages a tab 58 of the plug 60 when the isolator is switched ON. A spring-biassed abutment 56 prevents the isolator from being switched ON in the absence of a plug by preventing movement of the locking member 51. The abutment 56 is moved away from the locking member 51 when the plug mates with the socket. Instead of gears, the interlock may have an ungeared rotary link, or a pivotal link when the knob is actuated with linear and not rotary movement. More than one abutment may be provided. The or each abutment may be located in a guideway for a key of the plug. <IMAGE>

Title: A domestic electrical appliance removable from a base
Inventor: PROSSER DARREN
IPC: H01R24/38
Filed: 1997-08-16
Abstract: The invention relates to so called "cordless" domestic electrical appliances, such as jug kettles,in which the appliance 1 itself is separable from a base unit 3 and can rotate freely relative to its base about the axis of co-operative parts 4,5 of a coaxial connector. The invention provides means whereby a functional parameter of the appliance differs and/or is implemented differently in dependence upon its rotational position relative to the base. In one example, the appliance is a kettle which carries a circuit arrangement 6 capable of giving an audible warning when the kettle's contents have boiled, and the operation of that circuit arrangement is enabled or disabled in dependence upon the rotational position Magnets 8 and suitably responsive reed switches 7 may be used to effect the selective enabling and disabling. Alternatively, power settings or cut-off temperatures may be varied by the rotational position, or an electric descaling device may be enabled. The different positions may be indicated by visual or tactile means.

Title: Scrambling and descrambling apparatus
Inventor: CHO MIN-SOO
IPC: H04N21/4405
Filed: 1997-09-24
Abstract: A scrambling apparatus scrambles a video signal by superimposing a scrambling signal on a video signal to be scrambled in a pay television system. In the apparatus, horizontal and vertical sync separators 604,606 separates horizontal and vertical synchronizing signals from a video signal received to be scrambled, respectively. A counter circuit 608 counts the horizontal synchronizing signal M.SYNC in response to the vertical synchronizing signal V.SYNC from the vertical sync separator 606 to generate a count signal CS when the count reaches a first predetermined value. A reference clock generator 610 generates a reference clock signal RC based on the horizontal synchronizing signal H.SYNC from the horizonal sync separator 604. A switch 612 selectively transfers either one of an unscrambled signal of the video signal P1 or a scrambling pulse P2. A control section 614 controls the switch 612 based on the horizontal synchronizing signal H.SYNC from the horizontal sync separator 604, the count signal CS from the counter circuits 608, and the reference clock signal RC from the reference clock generator 610.

Title: Voltage controlled oscillator
Inventor: LAI BENNY W H
IPC: H03B1/00
Filed: 1997-11-12
Abstract: A dual input voltage controlled oscillator 5 suitable for use in clock and data recovery(CDR) systems operating at 1005 to 1,000s of MB/sec is described. When a PLL using this vco 5 is locked onto a data stream of a fixed bit rate, the bang/bang frequency of the vco does not vary due to process and temperature variations occurring either during manufacture or operation. The vco is also relatively insensitive to supply voltage variations. This is obtained by arranging the time difference between the periods of the two bang/bang frequencies divided by the oscillation period to be a constant fraction independent of variations in the above parameters. The oscillator may be a ring oscillator including a plurality of variable delay cells 10 and having its centre frequency controlled by an analog control voltage. The bang/bang frequency is controlled by controlling the delay time through the cells 10 by means of a modulation current variable in dependence upon a digital bang/bang input.

Inventor: JOHNSON MICHAEL H
IPC: E21B37/06
Filed: 1997-05-01
Abstract: The present invention provides multi-branched wellbore systems and methods for forming and utilizing such wellbores. An access wellbore is formed substantially in a non-producing formation. From the access wellbore are drilled one or more branch wellbores into producing formations and into non-producing formations. Additional branch wellbores may be formed from the access wellbore or the branch wellbores. Seals between the access wellbore and the production wellbores are formed outside the hydrocarbon-bearing formations. Flow control devices and other devices are installed outside the access wellbore, thereby utilizing the access wellbore primarily for transporting fluids during production of hydrocarbons. The distance between the access wellbore and any other desired formation, such as the producing formations, is determined during drilling of the access wellbore, preferably by utilizing acoustic sensors deployed in a drilling assembly. The distance between the access wellbore and the various formations is utilized for adjusting the drilling path of the access. The branch wellbores may be utilized for storing equipment, processing and/or treating fluids, compressing gas, and redirecting gas and water downhole to improve hydrocarbon production.
