Title: Motor/manually driven sliding variable resistor
Inventor: ASANO MASAHIRO
IPC: H01C1/14
Filed: 1996-02-21
Abstract: A motor/manually driven sliding variable resistor is provided which can be simply assembled and can prevent the occurrence of noisy sounds in motor-driven operation. The motor 7 drives a driving pulley 8 and toothed belt 11 to move the slider pieces 25, 26 of the resistor. A guide member 9 is disposed around the driving pulley 8 to leave a gap a smaller than the tooth height b of the belt teeth 11a between the guide member 9 and the belt 11. This stops the motor when the slider pieces have reached their end positions, thus reducing noise. An annular groove (20a, figure 6) is formed in the support shaft (20) of a belt driven pulley 10. The support shaft 20 is inserted into opposing slots/holes (17a, 16a) in opposing plates (17, 16) such that the annular groove (20a) grips the plate (17). The driven pulley 10 is then held on the resistor support frame 6 by utilizing the tension of the belt 11. The slider pieces 25, 26 are held on a slider receiver 22 mounted to a manually movable belt operating member 21, the belt being tightly held between the operating member and slider receiver. A protruding lug (22c, figure 8) formed on the slider receiver 22 is inserted into an L-shaped portion (21e) formed on the operating member 21, tightly holding the belt 11 between the lug and L portion. At the same time, a latch pawl (21h, figure 9) is snap-fitted into a latch groove (22e, figure 11) for joining the operating member 21 and the slider receiver 22 together into one unit.

IPC: A61B18/00
Filed: 1996-05-03
Abstract: Fluid (12) contained in a vessel (10) is heated by means of infra-red light sources (20 and 22). The infra-red light passes through the wall of the vessel (10) and is absorbed directly by the fluid. A control circuit (34) controls the operation of the light sources (20 and 22) to maintain the fluid at a desired temperature, or within a desired temperature window. A probe (24) carries at least one temperature sensor (26 and 28). The sensor measures the temperature of the fluid, and the behaviour of the sensor output also indicates whether the fluid level has fallen below the level of the sensor (28), whereupon an alarm signal is produced by the control circuit (34). The system is used in a warming system to protect healthy body tissue from unintended freezing during cryosurgery.

Title: Dimmable electronic ballast for a gas discharge lamp
Inventor: ZENG XIAOMING
IPC: H05B41/392
Filed: 1997-06-13
Abstract: A gas discharge lamp 43 is connected to MOS-FET's 36, 37 of a half-bridge inverter circuit which has an inverter driving integrated circuit 31 connected to means for pulse width control of the MOS-FET's 36, 37 during both pre-heating of lamp filaments 41, 42 and for dimming of the lamp 43. For soft-starting, the inverter initially operates at a minimum pulse width during a pre-heating period determined by an RC circuit 16, 19. A first DC power supply 7, 8 initially provides a maximum of 5 volts to the supply terminal VCC of the driver IC31. A second DC power supply, including a transformer 45, 46, gradually increases the supply for IC31 to 15 volts, resulting in a transistor 20 being controlled so that the pulse width of the inverter gradually increases to a maximum value. Pulse width adjustment for lamp dimming is also effected by controlling transistor 20 by means of a control signal input 57, 58 coupled to the transistor 20 via an opto-coupler 56. Increasing the control signal increases the conductance of transistor 20, thereby reducing the pulse width and reducing lamp brightness. An over-current protection circuit senses lamp current by means of the transformer 45, 46, excess current causing an SCR 10 to latch a transistor 17 on, whereby the transistor 20 is also latched on.

Title: Electronic commerce system where credit card details are not transmitted over insecure networks
Inventor: PHILLIPPS JOHN QUENTIN
IPC: G06Q30/00
Filed: 1999-06-10
Abstract: Users 101-103 access vendors 107,108 via the PSTN 104, internet service provider (ISP) 109 and the internet 106. The vendors are registered with the ISP so that when a user makes a purchase the ISP recognises and intercepts the Action URL of the vendors credit card details submission form. The ISP sends the form to the transaction computer 112 of a financial services provider over a leased line 115. The transaction computer checks the form and replies with a 'not approved' message or an 'approved' message including a transaction ID. The ISP then either forwards the 'not approved' message or replaces the credit card details in the credit card details submission form with the transaction ID and forwards the modified form to the vendor. The transaction ID is then submitted to the financial service provider along with the request for payment, and validated against the financial service providers records before payment is authorised. Thus the credit or debit card details are only transmitted over the relatively secure PSTN links 4 and the leased line 115. The financial services and internet service providers may alternatively constitute a single entity (see Fig. 1).
Patent GB-2352370-A (GB)
Title: Migration from in-clear to encrypted working over a communications link
Inventor: PARKER THOMAS ANTHONY
IPC: H04L29/06
Filed: 1999-07-21
Abstract: A system involving a central computer (27) and a remote computer (24) which can communicate over a link (29), is migrated from in-clear working to encrypted working automatically as the computers receive and install long term keys necessary for encrypted communication. When migration is required, the settings at both ends of the link need to be changed to "encrypt" simultaneously and, particularly, if there are numerous remote computers and the possibility of connection of a remote computer to different central computers, as is possible in virtual private network (VPN) scenarios, severe problems can ensue. Hence, as well as the normal two modes of working "in-clear" and "encrypt", a third mode in which "initiate encryption" is set at one end of the link and "accept encryption" is set at the other end of the link, is proposed. This third mode ensures that working in-clear can continue over a particular link, such as between a particular VPN server (27) and a particular security gateway PC (24), until a long term key required for encrypted working is installed at both ends of the link, but that once key installation is complete, only encrypted working is possible over that link. The link may be a tunnel 29 over a shared network 23.
