Title: Communication system for radio controlled toy vehicle
Inventor: WEISS STEPHEN NICHOLAS
IPC: A63H30/00
Filed: 2002-01-22
Granted: 2010-04-13
Abstract: A communication scheme is employed for transmitting control signals from a remote control (210) to a toy vehicle. The remote control includes control switches, an encoder and a transmitter (224) and the toy vehicle in accordance with received control signals. The encoder generates a continuous stream (102) of control signal packets (100) with each of the packets (100) including a predetermined number of biphase encoded bits. Each biphase encoded bit is of the same predetermined width with a 50 % duty cycle, including two transmit elements. For one binary state, both of the transmit elements are the same and for the other binary state both of the transmit elements are opposite. Each packet (100) includes a first predetermined number of flag bits (104), a second predetermined number of data bits (108) and at least one checksum bit (106).

Title: Storage and transportation of aluminium strip
Inventor: WRIGHT DAVID SKINGLEY
IPC: B21C47/32
Filed: 2001-12-04
Granted: 2009-09-08
Abstract: The invention is particularly directed to the problem of creep deformation in a coiled aluminium strip, which occurs during coiling and for a period thereafter. the problem arises because the profile of the strip across its width is not flat, and is in fact usually thicker in the middle than at the edges (positive crown). To cater for this, the invention provides that the spool (1) onto which the coil is wound is adapted to provide more support to the strip in the centre than at the edges. Various ways of achieving this are described; one example, as illustrated, is to make the central portion (2) of the spool (1) of greater diameter than the end portions (3) of the spool. A  strip having a positive crown which is wound onto such a spool was found to exhibit significantly reduced creep strain, leading to reduced creep deformation.

Title: Sealed pressure indicator
Inventor: MARTIN RONNIE LEE
IPC: F16F9/32
Filed: 2001-12-12
Granted: 2008-12-09
Abstract: A pressure indicator (106) according to the present invention monitors the pressure of the fluid in a vessel (102). One embodiment of the present invention comprises a closed pressurized gas volume (210) behind a dimpled metal diaphragm (208). In normal operation, the force of the fluid pressure acting on the external surface of the diaphragm (208) to hold the diaphragm (208) in a concave geometry. In the event of a sufficient loss of fluid pressure, the force of the gas pressure acting on the internal surface of the diaphragm (208) will overcome the force of the fluid pressure acting on the external surface of the diaphragm (208), thereby moving the diaphragm (208) into a convex geometry. A viewing window (110) disposed in the side of the vessel (102) can be used to view the pressure indicator (106) and determine the shape of the indicator diaphragm (208).

Abstract: A mosaic image resembling a target image is composed of images from a data base. The target image is divided into regions of a specified size and shape, and the individual images from the data base are compared to each region to find the best matching tile. The comparison is performed by calculating a figure of visual difference between each tile and each region. The data base of tile images is created from raw source images using digital image processing, whereby multiple instances of each individual raw source image are produced. The tile images are organized by subject matter, and tile matching is performed such that all required subject matters are represented in the final mosaic. The digital image processing involves the adjustment of colour, brightness and contrast of tile images, as well as cropping. An image description index locates each image in the final mosaic.
