Abstract: A control circuit generates an optimized radiation treatment plan with respect to an adjustable collimation device and then automatically generates at least one quality assurance accuracy value corresponding to the optimized radiation treatment plan. By one approach, the aforementioned plan comprises a plurality of treatment fields. In such a case, automatically generating at least one quality assurance accuracy value can comprise, at least in part, automatically generating at least one quality assurance accuracy value for each of at least a substantial number (or all) of those treatment fields. By one approach, the aforementioned quality assurance accuracy value comprises a dimensionless metric. This dimensionless metric may represent, for example, dosimetric accuracy corresponding to the optimized radiation treatment plan.

Abstract: A keyboard assembly (20) has a light guide (23, 31, 33) and a supporting structure (23, 33) arranged to provide an illuminated and integrated keyboard assembly (20). A light guide (23, 31, 33) provides an integrated supporting, protecting and illuminating structure for keyboard assemblies (20). The keyboard assembly (20) has a layer of rigid material (31) which separates the elastic layer (21) from the printed wired board (9) located under the rigid layer (31). The layers are bonded together. The protection rib (33) is part of the combination of the elastic layer (21) and rigid layer (31) which is supported against the printed wired board (9) by the rigid layer (31). The combined structure of the light guide and supporting frame forms an integrated structure (23, 31, 33) which illuminates an array of keys (22), supports the keyboard assembly (20) and protects the keys (22) and key tops 25 from mechanical stress.

Abstract: A cordless telephone handset. The cordless telephone handset has telephone circuitry with a front side. The front side of the telephone circuitry has a top end and a bottom end. A housing is provided having a top shell and a bottom shell where the top shell and the bottom shell are disconnectable. The housing is adapted to substantially enclose the telephone circuitry when the top shell and the bottom shell are mated in a direction from the top end to the bottom end of the telephone circuitry.

Abstract: An electronic device such as a mobile phone having user changeable composite covers formed by a two-shot process. The covers are removable and are adapted to slide onto and off the electronic device/mobile phone to thereby enclose the electronic device/mobile phone in a water-resistant/dustproof manner. The composite covers include resilient regions with buttons formed therein that cooperate with control elements in the electronic device/mobile phone. The composite covers are formed by a two-shot process that involves the use of a transparent material in a first shot to provide a hard cover having a number of openings there through. The second shot involves the use of the transparent hard cover as a core onto which an elastomeric layer is applied, so that some of the openings in the hard cover have buttons formed thereon, whereas other regions and openings in the cover are not covered.

Abstract: An electromechanical structure is provided for a portable radio device. In comprises a circuit board (302, 401), a number of components (301, 402) attached to the circuit board, a conductive shield (303, 304, 404, 407) for enclosing the components and an essentially planar antenna radiator (305, 410). A part (304, 407) of the conductive shield is essentially planar and adjacent to the antenna radiator (305, 410) in order to function as a ground plane for the antenna radiator.
