  • Patent number: 6625469
    Abstract: There is provided a radio telephone having an arcuate support (114, 1008, 1506) positioned at an upper portion (104, 1002, 1502) of the radio telephone's housing (102) for attachment to a loop-shaped object, such as a belt loop, bag strap and the like. The arcuate support (114, 1008, 1506) includes a first section (110, 1004, 1504) that is stationary relative to the housing (102), and a second section (112, 1006, 1506) that pivots away from the first section (110, 1004, 1504) to open the support (114, 1008, 1506) and returns back to the first section (110, 1004, 1504) to close the support (114, 1008, 1506). Depending upon the embodiment of the radio telephone, the arcuate support (114, 1008, 1506) may open by moving the second section (112, 1006, 1506) inward from the first section (110, 1004, 1504), outward from the first section (110, 1004, 1504) or both inward and outward relative to the first section (110, 1004, 1504).

  • Publication number: 20020090099
    Abstract: The subject invention is a portable communication device (100) having a lanyard-like structure that is generally hung around a user's neck. In particular, the device includes an earpiece (106) for providing incoming audio or voice information to the user's ear and a mouthpiece (104) to receive outgoing audio or voice information from the user's mouth. Also, one end (108) of a flexible elongated cord (102) is attached to one part (216) of the mouthpiece, and the cord passes through another part (212) of the mouthpiece to form a loop to one side of the mouthpiece that is placed over the user's head. The mouthpiece may be adjusted to many different positions along the cord. The earpiece is attached to the other end (110) of the cord and may either hang down from the mouthpiece or be positioned on the user's ear. An electrical conductor (202) is positioned through the cord to electrically connect the mouthpiece to the earpiece, and a wireless transceiver (404) and a microphone (408) are located in the mouthpiece.
