Abstract: A multipurpose keyboard (10) incorporating an electronic pressure sensing device (11), a digitizer pad (12) featuring spatial minimization of a pressure contact area capable of locating the leading and trailing edges of the pressure contact area is described. A processor (24) coupled to the electronic pressure sensing device is programmed to sense when various regions on a simple, fully interchangeable template overlay and the underlying electronic pressure sensing device are depressed. The sensed region is associated by the processor with a particular key (16) identification on the template overlay. The variation of the resistance in the digitizer pad enables the processor to detect the actuation of more than one key on the template overlay at the same time, thereby detecting key rollover. A method of fabrication for a multipurpose keyboard is also described.

Abstract: A communication system including a transmitter (10) and a transceiver (11) for controlling the operation of multiple receivers (24-30). The transmitter sends data packages as an IR signal and also has a receiver (16) for sensing the transmission of IR packages from a transceiver. The transceiver receives the IR packages from the transmitter and transmits IR packages from the transmitter to any one or more of the multiple receivers. When the transmitter sends a stop signal (15) this is not transmitted or received by the transceiver until the transceiver is a space mode between data packages. This permits for coordinated transmission between the transmitter and transceiver and ensures that signals from the transmitter do not overlap transceiver output signals.

Abstract: A thermally stable, mass-producible pointing device (10) producing an analog signal proportional to an applied force comprises actuator (20), including an arm (22) and a force transfer member (26), a connector (44), and a sensor (50). The connector maintains the force transfer member in contact with the sensor yet allows the force transfer member to change dimensions with ambient temperature without inducing stresses detectable by the sensor. In a preferred embodiment, the connector comprises an elastomeric adhesive and the sensor comprises a force-sensing resistor. The force transfer member is prevented from coming out of the assembly either by a retainer (12) comprising a shell or a potting compound retaining the force transfer member but permitting thermal expansion or contraction of the force transfer member. The force transfer member typically has a rounded or bevelled bottom surface (28) so the actuator rocks under an applied force. The area of the bottom surface of the force transfer member transferring the force changes as the actuator rocks, and the force is transferred to the sensor at a single contiguous area whose position changes in response to a change in force.

Abstract: A two-axis tilt sensor, or inclinometer (10), uses a spherical reference element (18) floating in an inert fluid (20) and including a magnet (42) to produce an asymetrical weight distribution. The asymetrical weight distribution maintains the spherical reference element at a constant orientation with respect to gravity, while the position of the magnet on the spherical reference element with respect to a housing (12) is detected by opposing pairs of Hall effect sensors (22) mounted on the housing. The outputs from opposing pairs of sensors are processed by differential amplifier circuits (80) to determine signals corresponding to the tilt of the inclinometer about the axes.

Abstract: An isometric pointing device that has the click function incorporated into the device, rather than as a separate switch. The pointing device implements the operations of pointing, clicking and dragging based solely upon an evaluation of the pressure applied thereto. An array of sensors is monitored. The cursor direction is determined by the difference or ratio of applied force between the arrayed sensors. Cursor velocity is determined by the magnitude of the applied force. When a click is desired, the pointing device is pressed downward. The transient nature of the tap or its nearly vertical force nature causes the output of the pointing device to readily distinguish between pointing and clicking operations. Pointing is also disabled during the click and for a short time thereafter. The time delay for disabling the pointer is short enough not to be detectable to the user, but long enough to inhibit cursor motion during a click.

Abstract: A pressure transducer includes a base ply (12), a resistance ply (14) disposed on the base ply and at least two spaced apart contacts (26, 28) juxtaposed in relation to the resistance ply whereby at least one of the contacts may be pressed against the surface of the resistance ply. The resistance ply is made by spraying or silk screening a mixture of resin (18) resistive to electrical conduction and a conductive particulate (16) and then curing the composition to form a thin resistance ply having a surface with a multiplicity of micro-protrusions (34) formed by the conductive particulate. The ratio of conductive particulate to resin is such that the mean distance (21) between microprotrusions is greater than about five times the size of the conductive particles (16). The particles are in the range of about .5 to 10 microns and the resin layer is about .4 to .8 microns thick.

Abstract: An adaptive keypad which has one or more keys includes, for each key, a pressure transducer (14-18) positined below a semi-rigid face plate where the pressure transducer has a resistance which decreases as the pressure compressing the transducer increases. The transducer is connected in series with a capacitor (26) to define an RC circuit for each key. Each RC circuit has a charge time proportional to the pressure applied to the key. A time capture circuit initially and thereafter intermettently, obtains the charge time for each RC circuit for each key and computes a conductance value from that time. The initial conductance value is stored in a memory (30). A comparing circuit intermittently compares the initial conductance value with each subsequent conductance value generated for a key. If the comparison value generated is greater than a predefined amount, a signal is generated indicating that a key has been depressed. If the comparison value is greater than a predefined amount over a selected period of time indicating a key is permantly depressed, the initial conductance stored in the memory for that key will be modified to a new value against which subsequent comparisons will be made to determine if a key is depressed.
