    Abstract: A quick release mechanism having a lifting ring (34) and a support ring (30) generally surrounds a shaft to be clamped (20). A cam or other lifting mechanism(32), operated by a handle (42), acts to separate the support ring and the lifting ring in a direction in line with the shaft. A restraint and adjustment nut(40) mounted on the end of the shaft in contact with the lifting ring acts to tension the shaft. The lifting mechanism is free to rotate about the shaft independently of the restraint and adjusting nut allowing the handle to be used in any orientation desired and preventing the handle from being used as a crank or wrench. Embodiments are provided allowing retrofit to existing shaft fastening applications, including those where access to the interior of the shaft must be maintained.

    Abstract: 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.

    Abstract: A pressure sensitive transducer array in which a plurality of transducers are connected in series and in parallel with one another. In one embodiment, a resistive layer is formed from carbon or silver ink on a polyester film. A plurality of conductive shunt elements having greater conductivity than the resistive layer is formed on a second polyester film. The films are placed adjacent to one another with the shunt elements contacting the resistive layer. Voltage is applied across the resistive layer and pressure is applied thereto. As the pressure increases, the number of current paths set up through contact points on the shunt elements increase thereby decreasing the resistance across the resistive layer and increasing current flow. In another embodiment a plurality of plate elements are contained in a plane on one side of a dielectric layer. A plurality of plate elements are contained in a plane on the other side of the dielectric layer. As the layer is pushed together responsive to force applied, total capacitance as measured across the planes of plate elements varies.

    Abstract: 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.

    Abstract translation: 多功能键盘系统中的数据采集包括通过常规键盘扫描技术来获取打字数据，并且同时通过与多功能指点键相耦合的力传感器采样来获取指向数据。 键盘系统周期性地对力传感器进行采样，以确定定义零点的偏置值，并通过移动平均计算来更新偏置值，以补偿制造公差和长期漂移。 响应于来自主处理器的开始指示命令，键盘系统传送偏差值，然后指示值，后者响应于用户对指针键施加的光标进行光标控制。 传感器值被编码，以便以对应用软件透明的方式传递到主机处理器。 只要指示模式持续，系统将周期性扫描力传感器以获取连续的指向值，并将其传送到主机。 同时，键盘系统扫描键盘以检测其他关键更改，并将其转发到主机。 钥匙开关数据可以被解释为指向事件（类似于鼠标按钮动作），或者作为改变为打字模式的指示。

    Abstract: A computer system employs an integrated keyboard and pointing device to allow user input of alpha-numeric (typing) information, pointing direction information and pointing event information without moving the users's hands from the usual typing position on the keyboard. The new system has typing and pointing modes of operation. In the pointing mode, preassigned keyswitches are used to input pointing events, cursor speed changes, and other modifications to the system's operation. All such modifications are transparent to the operating system and application software because they are processed at keyboard interrupt level.
