Abstract: A memory card connection device includes an upper card connector stacked on a lower card connector. The card connectors have a rear connector section from which two guide racks extend toward a front card receiving port thereby defining therebetween a first space sufficient for accommodating a type I or type II memory card. A single cover plate is positioned on and fixed to the upper card connector. The cover plate has a low level section directly fixed to the rear connector section of the upper card connector and a high level section positioned above the guide racks and connected to the low level section by a riser panel thereby forming a step-like configuration. The high level section of the cover plate is distant from the upper card connector thereby defining a second space therebetween in communication with the first space of the upper card connector thereby defining an enlarged overall space for receiving a type III memory card without interfering with the lower card connector.

Abstract: A card ejection mechanism for a card connector including a guiding frame, a rear actuating arm, a spring for urging the rear actuating arm rearward, a front actuating arm, and a follower pivotably connected to the rear actuating arm. The guiding frame has an inner space, a positioning groove within the inner space, and a channel. The rear actuating arm is slidably received in the inner space between a forward and a rearward stagnation positions. The front actuating arm is slidably received in the channel and has a front end adapted to operate a card ejection plate. The follower has a projection extending into the positioning groove and is moveable together with the rear actuating arm along the positioning groove to actuate the front actuating arm in a controlled manner.

Abstract: An electrical connector including a pair of grounding plate on two opposite sides thereof and a pair of brackets on two opposite ends thereof. The grounding plates each have a number of hooks on one end thereof in contact with corresponding grounding contacts and have a number of engaging fingers on an opposite end thereof. The grounding plates are further in contact with the brackets which are grounded to a circuit board on which the electrical connector is mounted. A connector assembly is also disclosed in which the grounding plates on one connector positively contact the grounding plates on the other connector to ensure a proper contacting engagement.

Abstract: A program storage device and computer program product for performing merge transactions and non-failure rollback transactions between data structures without logging. The device and product comprise data structures objects (or consoles) comprising means for storing original attributes that define that object, means for storing apparent attributes merged into that object from the other object, means for storing a switch-to pointer, and means for storing a switch-chain pointer. The device and product may further comprise merging means for processing merge transactions, including means for switching the switch-to pointer of the second object to point to the first object, means for switching the switch-chain pointer of the first object to point to the second object to thereby form a switch chain, and means for logically ORing the apparent attributes of the first and second objects to thereby render the second object idle and permit the first object to control the attributes of the second object.
