Abstract: A key for user input having superior tactile qualities. The key is suspended by a magnetic field force to improve the smoothness of motion. Two compact interleaved members link a keycap to a key base to provide highly precise parallel travel with reduced tilt and flexion, and improved durability.

Abstract: A collapsible compact touch-type keyboard for mobile devices. The keyboard includes a plurality of separate parts that together form a keyboard with keys large enough to allow efficient touch-typing. The plurality of parts includes at least a first and a second base each retaining a plurality of keys. A wireless transmitter exists within at least one of the parts to send keyboard events to a computer.

Abstract: An ultra-compact wireless keyboard in separable components, with an associated stand to support mobile devices. The invention uses separate key arrays which can be attached or dissociated, to deploy in a layout suitable for touch typing, or to collapse into a compact form for convenient transport. The stand provides for inclined operation of a mobile device with only a small additional volume. The keyboard may also provide for password characters to be stored internally, and transmitted automatically to a mobile device.

Abstract: An ultra compact mobile keyboard. The keyboard has a plurality of mechanical keys suitable for touch typing. Each such key has a travel distance sufficient to provide a touch type feel and a rigid cap for crisp actuation by a user. The keyboard has a deployed configuration for touch-typing use and a collapsed configuration for transport and storage. In the collapsed configuration, the keyboard fits within bounding volume of less than 180 cubic centimeters.

Abstract: A touch-type keyboard with multiple functions associated with each key which functions are uniquely selected based on finger position. Each of a plurality of mechanical keys are associated with at least three functions. Each key has a surface area for actuation by a user's finger. The surface area is mapped to zones associated with each function. Function actuation is determined by detection of the finger position when the key is actuated. In the event of a finger overlapping multiple zones during actuation, unique function selection is determined at least in part from the pattern of finger overlap with the plural zones.
