Abstract: A keyboard assembly includes a transmitter electrode and one or more receiver electrodes that are used to generate an electric field above one or more keys of the assembly. The first electrode is located on a first level of a keyboard assembly and the second electrode is located on a second level of the keyboard assembly. The first level may correspond to a support plate of the assembly and the second level may correspond to a surface of a printed circuit board to which the second electrode is coupled. Alternatively, the first and second levels may correspond to different sides of a frame of the keyboard assembly. Disturbances in the electric field may be detected to perform a control operation of a host device that includes or is coupled to the keyboard assembly.

Abstract: An improved assembly for a computer that includes a motherboard having a first side and a second side. The first side has a first portion and a second portion. The first portion contains components capable of generating substantial heat and a strong electric field. The assembly further includes an EMI attenuating cover that encloses the first portion of the first side of the motherboard, but does not enclose the second portion of the first side of the motherboard.

Abstract: A computer peripheral device retention apparatus is disclosed. In one embodiment, the apparatus includes a frame, a control arm slidably coupled to the frame, and first and second locking arms operably coupled to the control arm. A release button is received within the frame and is in operable association with the control arm. A release trigger arm is pivotally attached to the frame and a control arm latch is connected to the control arm at a first end and is releasably coupled to the release trigger arm at a second end. An ejection mechanism is attached to a rear end of the frame. A backplane printed circuit board is also attached to the rear end of the frame and an electrical control system is coupled to the backplane printed circuit board. A solenoid assembly is coupled to the electrical control system and is releasably coupled to the control arm.
