    摘要: A reactance buffer maintains a substantially constant reasonant frequency for an adjustable size loop antenna having first and second antenna segments. Each segment has first and second ends, the first ends being coupled to a receiver, and the second ends providing loop size adjustment. The reactance buffer comprises a reactance buffer input coupled to the second end of the first antenna segment. A plurality of taps are linearly disposed along a longitudinal axis of the first wristband section, and has a predetermined length between the outermost taps corresponding to the loop antenna size adjustment required. The taps provide selectable reactance buffer outputs for coupling to the second end of the second antenna segment. A plurality of reactance elements are arranged non-serially and couple the reactance buffer input to each of the plurality of taps and provide a substantially constant reactance measured between the reactance buffer input and each of the plurality of taps.

    摘要: A selective call receiver (110) and a receptacle (150) has in combination (100) a breakaway lock (120, 154), a non-breakaway hinge (124, 126), a track (116) and a slidably coupling having the breakaway lock (120, 154) and the non-breakaway hinge (124, 126) coupled with the track (116) for removing and replacing the selective call receiver (110). The breakaway lock (120, 154) has a tab (154) and a groove (120) for disengaging the selective call receiver (110) from the receptacle (150) at the breakaway lock (120, 154). The non-breakaway hinge (124, 126) forms a rotatable coupling for pivoting the selective call receiver (110). The non-breakaway hinge (124, 126) has a rail (126) and a geometric groove (124) terminating the track (116). The rail (126) and the geometric groove (124) allow the selective call receiver (110) to pivoted when the breakaway lock (120, 154) is disengaged while securing the selective call receiver (110) within the receptacle (150) when the selective call receiver (110) is pivoted and releasing it to be slidably removed when the breakaway lock (120, 154) is engaged.
