  • Thermoformed cover for electronic device and method for forming
    Publication number: 20070241021
    Abstract: A thermoformed cover and related method for forming the thermoformed cover for an electronic device including at least one body element is made from a thermoplastic sheet having characteristics and properties to accommodate the mechanical requirements of the cover for the electronic device. The thermoplastic sheet has characteristics such that when the thermoplastic sheet is heated to a suitable temperature, the thermoplastic sheet becomes pliable and stretchable. At least a portion of the heated thermoplastic sheet is made to conform by vacuum, pressure or other suitable means to a mold arranged to substantially correspond to the desired cover for the electronic device. A thermoformed cover corresponding to the desired cover for the electronic device is formed in at least a portion of the thermoplastic sheet and the thermoformed cover is cut away or otherwise separated from the thermoplastic sheet.

  • Antenna connector
    Patent number: 6426724
    Abstract: An antenna connector for holding an antenna in relation to a printed circuit board, where the antenna connector has means for releasable holding the antenna onto the printed circuit board. The holding means of the antenna connector are constructed to enable easy removal of the antenna from the printed circuit board so that components placed under antenna can be reached, repaired or replaced, and that the characteristics of a radio part on the printed circuit board can be measured without having the antenna mounted.
