摘要: A foldable keyboard having a plurality of folding keyboard sections. Each keyboard section includes a frame carrying a key set having a plurality of keys. The key set may be movable laterally relative to the frame. The frame with the key set is foldable with respect to an adjacent frame. The frame provides a self-contained enclosure for the keyboard assembly when fully closed. When opened, the keyboard assembly can be a full-size standard QWERTY keyboard.

摘要: A system and method for detecting key actuation in a keyboard assembly, which, in one embodiment, is used as a conductor to electrically communicate with an information appliance. The rows in the keyboard assembly are electrically isolated from one another, and each row contains keys bridging a two-wire bus. Each key has a switch that is closed during key actuation, a diode to polarize the key, and a resistor to provide a resistive load when the switch is closed and the diode is biased with the current flow. Alternatively, each key has a switch that is closed during key actuation, a timer with an output that goes high after a predetermined time period, and a resistor that provides an identifying load when the switch is closed and the output of the timer is high. Other features of the invention include a linear matrix coupled to a row of keys to allow the row to be scanned by sections and individual keys, and a flexible circuit that provides the electrical pathways for the linear matrix.
