摘要： A shock isolator (30) is provided within the housing (38) of a selective call receiver to substantially increase the natural frequency of vibration of the housing (38) and the printed circuit boards (54, 56) within the housing. The shock isolator (30) is a body of elastomeric material, preferably butyl rubber, which has component receiving apertures (32) molded therein for receiving the components (46, 48, 50) on the printed circuit board while at the same time contacting the printed circuit board. The butyl rubber has a damping of at least 25% (preferably 50%) and a Durometer of between 50 and 70 type A (preferably 60).

摘要： A low-profile motor arrangement for accomodation in a low-volume electronic device such as a radio pager. The motor is designed to provide a vibrating action for silent alerting that does not require any additional add-on parts, but effects the required vibrator action by a designed-in unbalance in the rotating internal parts.

摘要： A selective call receiver includes a vibrator (206) for generating alerts. The vibrator (206) includes a housing (402), a flexible member (2) within the housing (402) and coupled thereto, and a moving member (404) coupled to the flexible member (2) for movement about an equilibrium position, the moving member (404) including a permanent magnet (410). An actuator includes an electromagnet (412) for causing the permanent magnet (410) and the moving member (404) to move at a first frequency for generating an audible alert and at a second frequency for generating a sub-audible or tactile alert. The movement at the second frequency is substantially transferred to the housing (402) for generating the sub-audible or tactile alert.

摘要： Two or more crystal filter blanks are mounted together in such a manner so as to minimize the printed circuit board surface area occupied by their aggregate footprint and to minimize the vibratory and oscillatory interference among the cyrstal filters. Mounting devices are coupled to a first nonvibratory node and a second nonvibratory node of the crystal blanks to minimize vibrational and oscillatory interference between the crystal filters. Insulating material is disposed between the crystal blanks for electrically insulating and physically separating the crystal blanks from each other to additionally minimize electrical and vibrational interference between the crystal blanks.

摘要： A control console including a transceiver, a plurality of terminal stations positioned at spaced apart locations remote from the console and each including a transceiver connected to the console by RF or a wire line, and a plurality of call boxes positioned at spaced apart locations adjacent to each terminal station and including a transceiver in communication with the terminal station. When the hand set of a call box is lifted from the cradle a tone is transmitted through the adjacent terminal station to the console which then keys on all terminal station transmitters to indicate a busy line at other call boxes and to provide a ringing signal at the call box being used. Subsequent to transmission of the tone, a signal indicative of the address of the box and the condition of predetermined portions of the box is automatically transmitted to the console. When the console operator answers, full duplex communication is provided between the call box and the console.
