Title: Verifying the identity of a device or user in an electronic communications environment
Inventor: KEECH WINSTON DONALD
IPC: G06Q20/00
Filed: 2000-09-07
Abstract: A mask code is stored in a host computer 1 and issued to a user of a communications device 3. When the user is required to identify himself to the host computer, the host computer transmits a pseudo-random string to the communications device whereupon the mask code is applied to the string according to predetermined rules to generate a volatile identification code which is then transmitted back to the host computer. Positive identification is achieved when the volatile identification code matches a volatile identification code generated in the same way in the host computer. The communications device may be a mobile telephone. Identification may be required when a user attempts to use a credit card at an Electronic Funds Transfer Point of Sale (EFTPOS) terminal. The card identification code is transmitted to the card issuer host computer which responds by transmitting a pseudo-random string to the user's mobile phone. The volatile identification code is then returned to the host computer via the mobile phone or the EFTPOS terminal.

Title: A solar hot water transfer vessel
Inventor: HUNT JOHN
IPC: F28D1/02
Filed: 2001-05-31
Abstract: A solar water heated transfer vessel 9 comprises a solar water indirectly heated expansion compartment. Heated water from a solar panel may be circulated through a flow pipe 1 into an indirect chamber 2 and returns through a pipe 3. The indirect chamber 2 act as a heat exchanger for heating water in the transfer vessel 9. A diaphragm 6 allows for the expansion of water inside the transfer vessel 9. The cool water in a domestic hot water storage cylinder 10 is circulated by gravitational flow into the transfer vessel 9 where it is heated by chamber 2 before returning to the cylinder 10 via pipe 11. When solar heated water is at a lower temperature than the domestic water within the cylinder 10 gravitational flow ceases thus preventing cooling of the cylinder hot water store 10. Water may also enter the transfer vessel 9 via a cold water feed 13. The intermittent self-activating gravitational flow removes the necessity of having cylinder exchange, electronics and other controls.

Title: Varying frictional torque in a disc brake by varying frictional contact area
Inventor: SEYMOUR ROBERT JOHN
IPC: B60T1/06
Filed: 2001-09-27
Abstract: A car or bicycle disk-braking device has a pair of friction pads 46 having a predetermined area, which can clamp or release a disk 12 to reduce or stop rotation. The portion of the disk 12 passing between the friction pads 46 has a varying frictional contact area. In one embodiment, the varying area is formed by a series of spaced openings 22 having a circular or oval shape (22, fig 3). The opening spacing is said to be predetermined, and opening surface areas of parts of the series may increase or decrease by a constant ratio. The area of each opening 22 is smaller than that of the friction pads 46. Another embodiment has a frictional contact area with periodically changing boundary radii (fig 5). As the vehicle brakes, a periodic variation of the friction torque is generated which is said to prevent the wheels from sliding similar to an anti-lock braking system.

Title: Fast code acquisition
Inventor: SONG LICK HO
IPC: H04B1/707
Filed: 2002-05-20
Abstract: The invention relates to fast code acquisition in a direct sequence spread spectrum communication system. Previous fast acquisition has relied on the use of a threshold determined by estimations of the characteristics of noise. Small errors in the estimation can degrade performance. This invention uses a threshold defined by signed rank statistic. Three statistics are defined, for a locally optimum detector, and with various approximations, for a suboptimum detector or a modified sign rank detector.
