Title: Card activation at point of distribution
Inventor: ROTH JANET R
IPC: G07F7/02
Filed: 1998-12-18
Abstract: Secure activation of stored value cards (30) at a point of distribution uses a portable activation secure application module (ASAM) (208) within the card dispensing machine (24) to activate each card. Each card has a standard user mode and a security user mode. In the standard user mode the card is activated and ready for use. In the security user mode the card is not active and cannot be used to make a purchase. An issuer (20) supplies an issuer activation key (40) to a card supplier (22) who produces a security code (72) which is stored on a stored value card (30). Cards are supplied to the issuer (20) in security user mode, and stored in a dispensing machine (24).  The issuer activation key (40) is also relayed to the dispensing machine and stored on the ASAM (208). Upon purchase by a customer (26), the issuer activation key (40) is used within the machine (24) by the ASAM (208) to reproduce the security code (72) and to activate a card. An activation control counter (ACC) is stored within the ASAM and is decremented for every attempt at activation of a card. ASAMs are maintained in the field using a dial-up connection to a central computer (202) with a control secure application module (CSAM) (206), or using a field secure application module (FSAM) (502) that is created at a central location using the CSAM (206). Each FSAM is able to update a limited number of ASAMs. A hierarchy of keys (600) is used by the CSAM, the FSAMs and ASAMs to ensure security.

Patent CA-2326734-A1 (CA)
Title: Circuit simulating a diode
Inventor: JANSEN ARIAN M
IPC: H03K17/30
Filed: 1999-04-12
Abstract: A circuit simulating the function of a diode in the sense that it conducts current in one direction and blocks current in the opposite direction, but which has a low forward voltage drop. A voltage comparator (12) and a three terminal switch (10) are connected so that the intrinsic reverse diode (11) associated with the switch is harnessed to conduct current in the direction in which it is desired to conduct current and to block current in the direction in which it is desired to block current. A voltage comparator controls the control terminal (G) of the three terminal switch to turn on the switch to conduct current from a terminal A to a terminal K when the voltage at terminal A is higher than the voltage at terminal K and to interrupt current from terminal K to terminal A when the voltage at the terminal K is higher than the voltage at terminal A. The switch terminal (source or drain) that is typically connected to the higher voltage of two voltage terminals is instead connected to the lower voltage of the two voltage terminals. The switch may be a MOSFET, p- or n-channel, depletion or enhancement. Alternatively, a bioplar transistor (30) may be connected to a voltage comparator to simulate the function of a diode. Alternate embodiments of voltage comparators are disclosed. The invention further includes a method of conducting current in one direction and blocking current in a second direction which reduces power losses.

IPC: E21B47/09
Filed: 2001-01-25
Abstract: A wireless coiled tubing joint locator for locating joints or collars in a production tubing string. An electromagnetic coil assembly or giant magnetoresistive digital field sensor senses the increased mass of a pipe joint, and provides a signal to an electric circuit which generates a signal received by a pilot solenoid valve. The solenoid valve momentarily opens a pilot passageway which activates a piston to close a circulation port in the joint locator, resulting in an increase in a surface pressure reading observable by the operator. In one embodiment, a rupture disk is provided so that pressure cannot be applied to any downhole tool below the joint locator prematurely. A seat sleeve prevents premature communication of fluid to the rupture disk but can be opened by dropping a ball into the joint locator. A second embodiment may be used for either logging or washing operations or both. The electronic circuit can provide a selected one of a plurality of time delays. A fixed test period in the circuit delays activation of the time delay so that the joint locator may be tested before it is run into the well. The electric circuit and power supply are provided in a removable case.
