Abstract: Method and apparatus for controlling an injection molding machine having a first surface and a second surface includes a piezo-ceramic sensor configured to be disposed between the first surface and a second surface. The piezo-ceramic sensor is configured to sense a force between the first surface and the second surface, and to generate corresponding sense signals. Transmission structure is coupled to the piezo-ceramic sensor and is configured to carry the sense signals. Preferably, a piezo-ceramic actuator is also disposed between the first surface and a second surface, and is configured to provide an expansive force between the first surface and a second surface in accordance with the sense signals.

Abstract: Complete navigation of electronic media through very fine movements of a pointing device by application of a directional actuator having a next page actuator, previous page actuator, and media movement actuator. Errors associated with coarse pointing device movement are removed, and the usable display area inside the window frame is increased. Complete navigation includes horizontal, vertical and diagonal movement with a gradient of speed.

Abstract: The present invention relates to a dynamic hardware tracer for use in a circuit. The circuit is comprised of real circuitry which performs a real function and the tracer. The tracer is comprised of functional tracer circuitry which receives input signals from the real circuitry and processes the input signals. The functional tracer circuitry does not interact with the real circuitry to contribute to or modify the real function of the circuit. The dynamic hardware tracer provides an indication of a copied circuit. The present invention also relates to a dynamic software tracer located within a piece of software. The dynamic tracer is comprised of at least one line of software tracer code imbedded in a block of real software code. The at least one line of software tracer code interacts with a tracer output signal from tracer circuitry located in a circuit which also includes real circuitry which produces real output signals providing a real function.
