Abstract: A selective call receiver (100) comprises a battery powered receiver (104) for receiving and presenting a message, a battery having terminals for electrical coupling thereto, and a housing (208) enclosing the receiver (104) and the battery. The housing (208) has a first opening (206) for receiving the battery and at least one second opening (234) separate from the first opening (206) for securing a battery door (FIG. 4). The battery door (FIG. 4) provides access to the battery contained within the housing (208). The battery door (FIG. 4) comprises a hinged member (214) having a first end (238) coupled to the housing (208) for rotating between a closed position and an opened position, and a second end reduced to form a tongue (240).

Abstract: An electronic component, such as a speaker, is supported on the chassis of an electronic device, such as a small radio pager, by a resilient annular member which is latched to the chassis. The annular member has an inner surface for receiving a part of the component, such as the speaker pot, and a plurality of fingers extending from the member and inserted through an opening in the chassis with outwardly extending hook-like ends which engage the opposite side of the chassis. The member and fingers are flexible for mounting on the chassis, and are rendered more rigid when the component is inserted therein so that the fingers hold the member on the chassis. The annular member may include portions which are flexed when the component is placed therein to store energy which tends to move the component out of the member. When used for supporting a speaker, the member tends to move the speaker pot to hold the speaker edge against a grill which may be formed in the housing of the device.

Abstract: A crystal is mounted on a low, centrally located pedestal. Connections to the lower side of the crystal are made by way of conductive areas on the pedestal. Multiple wiring connections are made at the edges of the crystal by allowing the bonding tool to depress the edge of the crystal so that the crystal bonding pad is supported by the base structure only during the bonding process, then released thereafter to allow free vibration of the crystal plate. Complex circuitry, possibly involving more than one frequency can thus be put onto one plate.

Abstract: An improved housing assembly for housing miniaturized electrical or electronic apparatus, such as a radio receiver or monitor, is disclosed wherein a single piece housing is provided, open at the top for receiving an associated electrical chassis with self-contained battery compartment and a sound transducer. A control panel attached to the electrical chassis cooperates to overfit the open end of said housing to complete the overall assembly. The assemblage of the housing apparatus requires no screws, fasteners or special tools as the respective component parts effect a snap-fit with one another. A novel interlocking arrangement between chassis assembly and housing disguises the latching interfit therebetween, which nevertheless may be released by the insertion of a simple blade tool at the proper location. Complete shock mounting and protection from dust and dirt is effected by resilient gasket elements in cooperation with the housing and chassis assembly.

Abstract: An air droppable sealed warhead cannister capable of housing a plurality of omblets, each bomblet having a pressure-sensitive fuze capable of being controlled by the presence and absence of a predetermined pressure in the cannister.
