    Abstract: A non-linear reciprocating device (100, 200) includes an armature (12) including non-linear suspension member (14, 16); a compliant contactor (50, 72), coupled to a power source (BT), and further coupled to the armature (12) for generating an interrupting signal; an electromagnetic driver (25), coupled to the non-linear suspension member (14, 16) for effecting an electromagnetic field in response to the interrupting signal; and a magnetic motion mass (18) suspended by the non-linear suspension members (14, 16), and coupled to the electromagnetic field for generating a reciprocating movement of the magnetic motional mass (18) which is transformed through the non-linear suspension members (14, 16) and the electromagnetic driver (25) into tactile energy. The compliant contactor can be either a single pole compliant contactor (50) or double pole compliant contactor (72).

    Abstract: A method and apparatus adaptively selects a communication strategy for communicating a message in a selective call radio communication system including a fixed portion (100) and a portable portion (101). The fixed portion (100) transmits (402) an alert signal to the portable portion (101), and awaits (404) an acknowledgment signal including a signal quality estimate from the portable portion (101). The portable portion (101) receives (602) the alert signal, and computes (604, 606) the signal quality estimate therefrom. The portable portion (101) then sends (608) the acknowledgment signal to the fixed portion (100). In response to the acknowledgment signal, the fixed portion (100) selects (407) a transmission strategy in accordance with the signal quality estimate. For compatibility, the transmission strategy requires a matching reception strategy in the portable portion (101). After sending the acknowledgment signal, the portable portion (101) selects (609) the matching reception strategy in accordance with the signal quality estimate sent in the acknowledgment signal without requiring further communication with the fixed portion (100).

    Abstract: A global communications system is described having terrestrial transmitters (1108) for transmitting coded message signals in each of a plurality of geographic areas (1102, 1104, 1106). The global communication system further includes at least one satellite transmitter (1114) for transmitting the coded messages signals in each of a plurality of global geographic areas. The coded message signals transmissions include channel identification codewords identifying the terrestrial channels and the satellite channel. The terrestrial channel is selected for operation when the channel identification codeword received matches a first predetermined channel identification codeword. The satellite channel is selected for operation when the channel identification codeword does not match a second predetermined channel identification codeword. The terrestrial channel is periodically reselected when the channel identification codeword received on the satellite channel matches the second predetermined channel identification codeword.
