Title: Cipher type anti-theft system for cars using in-car wiring to transmit the cipher
Inventor: CHEN TSE-HSING
IPC: B60R25/00
Filed: 2002-12-27
Abstract: A cipher type anti-theft system for cars using an in-car wiring to transmit a cipher mainly includes an encoder/transmitter and at least one decoder cut-off relay. The encoder/transmitter generates a cipher and converts the cipher from digits to analog signals for loading onto the in-car wiring. The at least one decoder cut-off relay may be installed at any point on any power supply circuit needed to start the car. When the at least one decoder cut-off relay receives a correct cipher, it can decode the cipher and make the power supply circuit to allow start of the car. The encoder/transmitter and the decoder cut-off relay can be installed in the car without producing additional (ordirect) wiring and are therefore not easily found from outside. The encoder/transmitter may be an independent and portable unit associated with certain in-car equipment, such as a cigarette lighter, and uses the cigarette lighter holder, for example, as an interface to receive and transmit the cipher.

Patent TW-200307647-A (TW)
Title: Ion exchange regeneration system for UPW treatment
Inventor: CARSON WILLIAM W
IPC: B01J49/00
Filed: 2003-04-14
Abstract: An improved process for regenerating ion exchange resin, includes a regeneration step of displacing captured ions from the resin to regenerate its ion-capture functionality, followed by one or more fluid-employing post-regeneration steps such as a fluid displacement or rinse, a fluid transport or mixing, and a rinse down to quality. To avoid problems of early leakage of weakly held ions such as boron, the post-chemical or post-displacement steps use water that is essentially free of boron, or otherwise avoid localized contamination in the regenerated resin which is used in bottles or beds. The bottles or beds so regenerated or filled have low leakage, and their useful life can be accurately monitored or predicted by detecting conductivity or boron concentration in the product water. Once a bottle or bed is returned to service, leakage occurs at a detectable level when the unit becomes exhausted. To produce UPW water for regeneration, water may be selected by monitoring the polish beds or bottles for boron breakthrough, and stopping or diverting the product water when or before break-through occurs. A two-stage polish may be operated with modified lead/lag bottles. A detector for an indicator condition (conductivity, silica breakthrough) between stages determines when to shift the lag bottle forward, and periodically both bottles are replaced. Suitable regeneration may also be assured, even in the presence of rinse water carrying problemmatic species, by separating a sacrificial or phantom resin layer. This may be done by applying regenerated fluid treatments (rinses) in a directional flow, and separating the upstream regenerated resin which is thereby contaminated. Separation may be effected using a resin-filled cap or a cartridge that fits over or in-line with the tank or bottle during rinse down to quality.
