Abstract: In a dual-concentric knob, an inner knob acts as a solid ergonomically functional knob for forces below a threshold and collapses into an outer knob for forces above the threshold. In some examples the inner knob also acts as a push button for forces below the threshold. A hand-operated control is mounted on a hub for axial movement between a first position and a second position relative to the hub, a mechanism axially rigidly couples the control to the hub in the first position unless a force greater than a threshold is applied to the control, and a mechanism rotationally couples the control to the hub in both the first and the second positions.

Abstract: A media player facing has a device housing with a drawer and a facade. The outer surface of the facade and the outer surface of the device housing are aligned so that the facade outer surface and the device housing outer surface are substantially continuous when the drawer is closed.

Abstract: A PCMCIA electronics package adapted to enclose, and provides EMI shielding to, a printed circuit board (PCB). The PCB has an electrical connector adapted for plugging into a computer is at a one end and RF circuitry at the other end. Electronic components are disposed on an inner region of the surfaces of the PCB. The PCB has a ground plane conductor disposed therein. Electrically conductive strips are disposed on the surfaces of the PCB along opposing side edges and the other end of the PCB. A plurality of conductive vias pass through a portion of the PCB electrically connecting the electrical strip conductors to the ground plane conductor. A plurality of resilient, electrically conductive clips is provided. Each one of the clips has: a cup-shaped region disposed over a corresponding one of the PCB edges and the other end of the PCB. Side portions of the cup-shaped regions are in contact with conductive strips. The clips have an arm with a distal end elevated from the PCB.
