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.

摘要： By accessing the screen drivers of a host computer, a label printer provides a user of a host computer immediate printing onto a label of portions of a screen display generated by programs running on the host. A program controlling the label printer and executed by the host computer searches for and locates an address field on the screen, or data may be input to the screen by the user, to be captured for printing on a label. The data to be printed may be in alphanumeric format, graphic format, bar code format, or any combination of them.
