Abstract

Abstract A wrist band loop antenna for a device having a receiver which is intended to be worn on a wearer's wrist comprises a pair of wrist band loop segments which are coupled to the receiver for forming first and second electrical portions of the wrist band loop antenna. A conductive clasp couples to the first and second wrist band loop segments to provide adjustment of the length of the wrist band and provides electrical coupling between first and second wrist band loop segments to form the wrist band loop antenna. An insulator is provided to insulate the conductive clasp from the wearer's wrist which is coupled to the lower surface of the clasp.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 159 words
A wrist band loop antenna for a device having a receiver which is intended to be worn on a wrist, comprising: a housing for enclosing the receiver; a first and a second wrist band loop segment coupled to said housing and further coupled to the receiver, said wrist band loop segments forming portions of the wrist band loop antenna; a conductive clasp, having a first clasp portion coupled to said first wrist band loop segment and a second clasp portion coupled to said second wrist band loop segment, for adjusting the length of the wrist band, and for providing electrical coupling between said first and second wrist band loop segments to from the wrist band loop antenna, said second clasp portion including a lower surface positioned substantially adjacent to and in contact with the wrist; and insulating means, coupled to said lower surface, for insulating said conductive clasp from the wrist when the device is attached to the wrist.
Claim 2
Dependent Claim 159 words
A wrist band loop antenna for a device having a receiver which is intended to be worn on a wrist, comprising: a housing for enclosing the receiver; a first and a second wrist band loop segment coupled to said housing and further coupled to the receiver, said wrist band loop segments forming portions of the wrist band loop antenna; a conductive clasp, having a first clasp portion coupled to said first wrist band loop segment and a second clasp portion coupled to said second wrist band loop segment, for adjusting the length of the wrist band, and for providing electrical coupling between said first and second wrist band loop segments to from the wrist band loop antenna, said second clasp portion including a lower surface positioned substantially adjacent to and in contact with the wrist; and insulating means, coupled to said lower surface, for insulating said conductive clasp from the wrist when the device is attached to the wrist.
Claim 3
Dependent Claim 28 words
The wrist band loop antenna of claim 1, wherein said insulating means comprises: a clasp insulator; and attachment means for attaching said clasp insulator to said conductive clasp.
Claim 4
Dependent Claim 18 words
The wrist band loop antenna of claim 2, wherein said clasp insulator is formed from a plastic material.
Claim 5
Dependent Claim 19 words
The wrist band loop antenna of claim 3, wherein said plastic material is molded to form the clasp insulator.
Claim 6
Dependent Claim 15 words
