A full N-key rollover capability information entry device includes first and second sets of intersecting light guides oriented at an angle to one another which may comprise a mesh of waveguides that together form a self-supporting planar sheet of a substantially transparent material at the wavelength of light introduced into one end of at least one of the first and second sets of light guides. This permits each intersection to comprise a common portion of both a light guide of the first set and a light guide of the second set that intersect at that intersection. Detection of changes in the intensity of the light in at least one of the sets of light guides in response to key actuation that blocks a portion of the light at a certain intersection is indicative of that actuated key.

Optomechanical information entry device

The back cover of a TV cabinet is provided with a J-shaped latch member for releasable reception in a slot disposed in the cabinet front during cabinet assembly. The back cover is equipped with a window for providing access to the latch member, so that a tool can be inserted into the cabinet enclosure through the slot to release the latch member. The cabinet front is provided with a partition surrounding the latch member to prevent inadvertent insertion of a tool into the cabinet enclosure beyond the partition.

Snap-together latch for television cabinet

A snap-together latch mechanism for a television cabinet consists of at least one pair of oppositely-disposed, flexible latch fingers secured to the cabinet front and a corresponding number of oppositely-disposed, rigid stops disposed on the back cover. To attach the back cover, it is simply aligned with the cabinet front and inserted to lock it in place.

A plug-in cartridge designed to mate with an external system via a connector having a plurality of external mating receptacles, and one or more external actuator pins, for engaging the cartridge. The cartridge encloses a printed circuit board with terminals arranged to receive an electrical circuit (e.g., an integrated circuit) susceptible to damage by excessive electrostatic charge. The circuit board includes a plurality of metallic contact areas conductively connected to respective terminals, extending external to the cartridge, and configured to engage the mating receptacles of the connector. The cartridge also includes a protection device comprising a plurality of conductive fingers formed from a common conductive element. The device is arranged such that, when the cartridge and connector are disengaged, the fingers contact associated ones of the contact areas whereby the contact areas and therefore the circuit terminals are connected in common (i.e., shorted) to preclude circuit damage due to electrostatic charge. When the cartridge is mated to the connector, the actuator pins contact the device to lift the fingers off the contact areas, thereby permitting the electrical circuit to operate in expected fashion.

Insulator for an antenna

A support member mounted on an antenna boom includes a pair of upstanding spaced stanchions for supporting a signal feedthrough wire therebetween. An antenna element is pivotally mounted to the support member and has a bifurcated end which conductively connects with the feedthrough wire when the element is rotated from a folded closed position to an extended open position.
