    Abstract: A keyboard assembly incorporating multiple lighting modalities is disclosed herein. In one lighting mode, discrete indicator lights are embedded in the actuator keys to signify the state of an associated function. In a second mode, a plurality of legends, each sufficiently proximate to an associated function actuator key, are illuminated. In accordance with one embodiment of the present invention, function indicator lights in the actuator keys provide real-time user feedback such that scrolling through numerous display screen menus to determine availability of a desired function may be eliminated. Further, the backlit actuator legends enhances usability of system in low light clinical environments during ultrasound exams making the function actuator keys easy to locate. In addition, the backlit legends increases the contrast in high ambient light environments for improved readability. The combination of design features disclosed provides a relatively inexpensive, long lasting keyboard assembly that provides improved user feedback for more efficient operation.

    Abstract: Disclosed is a data entry keyboard which has a multitude of depressible keys which are selectively depressed for the entry of predetermined data. In the keyboard, an insulating member is sandwiched between a first substrate having stationary electrodes and a flexible second substrate having movable electrodes. The stationary and movable electrodes face one another through apertures formed in the insulating member. Upper and lower marginal surface portions of the insulating member, including the respective peripheral edges of the apertures, are kept parallel to the first and second substrates corresponding thereto by a plurality of protuberances on the substrates so that voids with a predetermined width are left between the marginal surface portions and the individual substrates. The movable electrodes of the second substrate are electrically fixed, in the form of a cantilever each, to the extreme end portions of branch conductor strips which diverge from a main conductor strip at right angles thereto. When one of the keys is depressed, the second substrate is deformed to narrow the corresponding void, thus bringing the corresponding movable and stationary electrodes into contact with each other.

    Abstract: A pressure-sensitive element for use in a keyboard switch etc., comprising a conductive porous material which is rugged, an elastic insulator which bulges more than convex parts of the conductive porous material without covering the convex parts, and a conductive layer which opposes to the conductive porous material through the elastic insulator. When no pressure is applied, openings are formed between the convex parts of the conductive porous material and the conductive layer through the elastic insulator, whereby the pressure-sensitive element is in its nonconductive state. When a pressure is applied, the elastic insulator is deformed to bring the convex part of the conductive porous material into contact with the conductive layer, whereby the pressure-sensitive element is brought into its conductive state.

    Abstract: A keyboard for a musical instrument having a plurality of elongated keys with each key having a rearwardly extending actuating arm. The arm has an upper and a lower nonresilient switch actuator for actuating a respective first and second keyboard switch with each switch having a substrate with at least one fixed contact. A deformable membrane has coupled thereto a movable contact which is adapted for movement into and out of electrical connection with the fixed contact. The first and second switches are positioned so that the lower actuator normally maintains closed the first switch and when the key is actuated the first switch opens and the upper actuator closes the second switch. The deformable membrane is formed of Poron cellular urethane which distributes and absorbs the actuation force and springs back to its undeformed shape when not actuated.
