Abstract: A semiconductor integrated circuit tester includes a housing having a main housing wall formed with an opening. A tester interface unit is located partially in the housing and incorporates an electrical connector segment that extends partially from the main housing wall for engaging an electrical connector segment of a device interface unit. A pusher member is located partially within the housing and is movable relative to the main housing wall between an extended position and a retracted position. In the extended position the pusher member projects from the opening in the main housing wall. An actuator is accessible at the exterior of the housing and is coupled to the pusher member for moving the pusher member between its retracted position and its extended position.

Abstract: A product change tool for selectively engaging a product change element with an IC tester interface and disengaging the product change element from the tester interface includes a mobile frame mounted to a base frame and constrained to move relative to the base frame along an axis of linear movement, and a force mechanism for urging the mobile frame to move along the axis of linear movement relative to the base frame. The force mechanism includes first and second links pivotally connected together at their proximal ends and secured at their distal ends to the mobile frame and the base frame respectively. The distal ends of the links are spaced apart along the axis of linear movement and the proximal ends of the links are between the distal ends relative to that axis.

Abstract: A test head for a semiconductor integrated circuit tester includes first and second card cages and first and second groups of interface connectors for engagement by DUT edges of pin electronics cards installed in the first and second card cages respectively. The interface connectors of the first group are inclined at an angle less than 180° to the interface connectors of the second group.

Abstract: A test head for a semiconductor integrated circuit tester, the test head includes a housing, a backplane structure attached to the housing in a manner permitting pivotal movement of the backplane structure relative to the housing, and a latch mechanism for forcing the backplane structure towards its closed position. The latch mechanism includes a cam follower that projects from the backplane structure in a direction perpendicular to the axis of pivotal movement of the backplane structure, a cam plate that is attached to the housing and is moveable relative to the housing and is formed with a cam slot for receiving the cam follower, and a drive mechanism effective to drive the cam plate to move relative to the housing. In the event that the cam follower is located in the working region of the cam slot, movement of the cam member in one direction urges the backplane structure towards the closed position and movement in the opposite direction urges the backplane structure away from the closed position.

Abstract: The enclosure assembly comprises a stationary member including at least two substantially parallel sidewalls, the sidewalls, the sidewalls partially defining a cavity in which the fingerprint sensor is disposed. An access piece, configured to move relative to the stationary member, has a surface area larger than the surface area of the fingerprint sensor and further includes a conductive portion electrically coupled to ground. A movement apparatus is preferably mechanically coupled to the stationary member and the moveable access piece. The movement apparatus is configured to maintain the moveable access piece in a position covering the fingerprint sensor and yet to allow motion of the moveable access piece relative to the stationary member so as to expose the fingerprint sensor. According to another embodiment, a method for enrolling a composite image of an object using a fingerprint sensor is provided.

Abstract: A semiconductor integrated circuit tester includes a generally parallelepipedal housing, a main tester board in the housing, and an interface unit incorporating a tester interface that is connected to the main tester board. A support mechanism supports the interface unit in a manner allowing pivotal movement of the interface unit relative to the housing.

Abstract: A semiconductor integrated circuit tester includes a housing having a tester interface area, a guide structure in the housing and defining an engagement axis that intersects the tester interface area, and a circuit board structure fitted in the guide structure in a manner allowing movement of the circuit board structure relative to the housing along the engagement axis. The circuit board structure has a tester interface that is exposed exteriorly of the housing at the tester interface area. An attachment mechanism releasably engages a test board having a test board interface and secures the test board against movement along the engagement axis in a direction away from the tester interface area. When the test board is secured to the housing by the attachment mechanism and the tester interface is not engaged with the test board interface, the circuit board structure may be urged to move along the engagement axis to force the tester interface into engagement with the test board interface.

Abstract: An appliance such as a personal computer includes a metal chassis which comprises a main chassis section and a subchassis hingedly connected to the main chassis section for rotation about a horizontal axis between folded-in and folded-out positions. The subchassis carries operational components such as a power supply and a drive, and the main chassis section carries an operational component such as a motherboard. When the subchassis is in its folded-in position it overlies the motherboard and blocks access thereto, and when in its folded-out position the subchassis provides access to the motherboard. In its folded-in position the subchassis sits upon horizontal edges of the main chassis section.

Abstract: An appliance such as a personal computer includes a metal chassis which has a first section, and a second section mounted on the first section. The first chassis section forms a first space in which a motherboard is mounted. The second chassis section forms a second space in which a disk drive is mounted. The second chassis section defines a shield resisting the passage of electromagnetic waves between the first and second spaces to isolate the motherboard from a disk opening for the disk drive thereof.

Abstract: A personal computer includes a chassis in which expansion cards and a processor card can be mounted in an upright parallel manner. An end of each expansion card is received in a vertical slot carried by a speaker component of the computer. A baffle member is swingably mounted on the chassis for rotation about a horizontal axis between open and closed positions. In the open position of the baffle member, the expansion cards can be inserted or removed. In the closed position of the baffle member, ribs thereof engage and stabilize upper edges of the cards. Hard and floppy drives are insertable into respective bays disposed within the chassis in a rear-to-front direction (in contrast to a front-to-rear direction), so that EMI shields located in front of those bays do not have to be removed to permit insertion or removal of the disc drives.

The enclosure substantially comprises a base, a unitary internal frame, a front and a back panel, and a U-shaped top cover. Frame-mounting snaps and cruciform members located on forward and rear portions of the frame mate to complimentary receiving openings in the base. Front and rear panels are mounted to the base, frame, and top cover by a plurality of panel-mounting snaps and hooks. A base electromagnetic interference (EMI) shield at the periphery of the shield having a plurality of planar tabbed fingers with hemispherical domes formed therein is then fitted and secured to the base such that the lateral edges of the fingers are recessed below a peripherally extending rim on the base. Thereafter, the internal frame is snapped into place upon the base, and a rear panel having an EMI shield fitted and secured to the base and frame by panel-mounting snaps and hooks.
