The piezo element is also used to detect switch bouncing when the switch transitions from the open position to the closed position. In one embodiment, the piezo element is a piezoelectric element and in another embodiment the piezo element is a piezo-resistive element. | ||||||

| 69 | Miniature isometric joystick | US685486 | 1996-07-24 | US5889507A | 1999-03-30 | T. Scott Engle; Patrick J. Franz |
| A miniature isometric joystick is disclosed for receiving manual user input to effect directional control such as controlling cursor movement on a computer display screen or controlling movement of an apparatus such as a machine or robot. The joystick is arranged to fit between the existing keys in a computer keyboard. The joystick includes a preloading spring for compressing the assembly together, thereby biasing the force sensors so as to neutralize manufacturing variations and control electrical and mechanical null zones. An integrated switch is provided in the joystick for detecting an external force applied by the user's fingertip. The switch unobtrusively detects when a user is pointing, thereby allowing a control system to measure pointing system bias signals while the user is not pointing. This permits the control system to automatically correct for drift, without requiring additional keyboard space for a separate switch to enable the pointing device. | ||||||

| 71 | Pointing stick in a computer keyboard for cursor control | US410348 | 1995-03-24 | US5568987A | 1996-10-29 | Patrick J. Franz |
| Apparatus for use in a computer keyboard for cursor control is disclosed. The apparatus includes a compound key which serves for both typing a character and for pointing operations, i.e. for cursor control like a mouse. For pointing operations, a pointing stick or shaft is pressed in a desired direction by a user for moving a cursor in a corresponding direction on a display screen. The pointing stick is disposed in an aperture that extends through a modified key cap, so that no additional keyboard space is required for the pointing device, thereby obviating a separate mouse, keyboard mounted trackball or the like. In an alternative embodiment, the pointing stick extends through an aperture in the keyboard space bar. In another embodiment, adjacent key caps are modified so as to fit closely around the key cap that houses the pointing stick without interfering with operation of either the pointing stick or the keyswiches. | ||||||

| 74 | Data acquisition in a multi-function keyboard system which corrects for preloading of force sensors | US672641 | 1991-03-18 | US5252971A | 1993-10-12 | Patrick J. Franz; Philip D. Biehl |
| Data acquisition in a multi-function keyboard system includes both acquiring typing data by conventional keyboard scanning techniques and, simultaneously, acquiring pointing data by sampling force sensors coupled to the multi-function pointing key. The keyboard system periodically samples the force sensors to determine bias values defining a null point, and updates the bias values by a moving average calculation to compensate for manufacturing tolerance and long term drift. In response to a start pointing command from the host processor, the keyboard system transmits bias values and then pointing values, the latter being responsive to forces applied to the pointing key by the user for cursor control. The sensor values are encoded so as to pass through to the host processor in a manner transparent to application software. The system scans the force sensors periodically to acquire successive pointing values, and transmits them to the host, as long as pointing mode persists. Concurrently, the keyboard system scans the keyboard to detect other key changes and forwards them to the host as well. The keyswitch data may be interpreted as a pointing event (analogous to a mouse button action), or as an indication to change to typing mode. | ||||||

| A keyswitch-integrated pointing assembly in which a plurality of substantially planar force sensing elements are disposed on a planar surface adjacent a keyswitch on a keyboard. The keyswitch includes a plunger which extends downwardly from a key cap for actuating a switch at the lower end of vertical key cap travel. The key cap engages an indexing surface when fully depressed which transmits force applied to the key cap to the force sensing elements. The force sensing elements are sandwiched between a pair of opposing plates thereby biasing the elements into a substantially linear operating region when no force is applied to the key cap. | ||||||

A perception unit(30) senses horizontal pressure in a specific direction of fingers positioned in the reference location within an input area and generates a first direction input signal. A second direction input signal is generated by sensing a perpendicular pressure in the specific direction. The sensing unit senses tilt pressure and generates a third direction input signal. The sensing unit generates a fourth direction input signal by sensing tilt of radiation directions around the reference location. | ||||||
