Title: Method and apparatus for making smart card solder contacts
Inventor: WONG CHI MING
IPC: H01R43/02
Filed: 2003-04-22
Abstract: A method and apparatus for soldering terminal ends of an antenna embedded in a plastic smart card to contact terminals of an IC module disposed on the card are shown. The enamel coated antenna terminal ends are pre-coated with solder with a heater having horizontal opening with melted solder retained therein. The solder pre-coated terminal ends are maintained in a secured contact with the terminal contacts of the IC module by heating coils mounted at a free front end of two pivotal elongated cantilever arms. A piece of predetermined amount of solder is dropped into the cavity of each heating coil, and the heating coils are actuated with a low electrical current to generate a concentrated intense heat to meld the piece of solder to form secure permanent solder joints between the terminal ends of the antenna to the contact terminals of the IC module.
Patent CA-2428838-A1 (CA)
Title: Bait container
Inventor: HATFIELD PETER DOUGLAS
IPC: A01K97/02
Filed: 2003-05-15
Abstract: A bait container having one or more sections for the slow release of bait, which are separated by layers of water soluble material. In use, the bait container is lowered into the water, having at least one section for the bait accessible to the catch.  The water soluble material then degrades over a period of time, permitting at least another section of bait to become accessible to the catch. In this manner, the water soluble material between the bait acts as a timed release, allowing the bait to fish longer.  The unit can be placed in the water for long term fishing, or a peel back tab can be removed from the bait container so as to provide for the immediate release of the bait. The invention therefore provides a means to prolong the useful life of the bait, particularly bait for crustaceans such as lobsters and crabs.

Abstract: A method of processing the sound associated with alarm events is disclosed. It is based on a transducer that converts the energy from acoustic to electrical form, a sampling device that converts it from continuous analog to discrete digital format, a memory that stores the compressed version of the event to be detected and an algorithm that compares the digital signature of the stored events with the digital signature of the event under development. When the result of the comparison as a matching, a triggering notification signal is generated. It is essential for this invention that the events that are stored in a compressed form into the memory can be specified by the user through a system training procedure during which the sound that is desired to be detected is processed by the system implementing this invention, and stored in the form of a digital signature.
