Abstract: Systems, methods, and devices are provided for handling module symbols. One embodiment includes a module link tool having a processor, a memory, and program instructions provided to the memory and executable by the processor. The program instructions are executable to translate a particular type of information associated with an object file into instructions to provide to a linker utility.

Abstract: The present invention provides a method and apparatus, including a processor and software incorporating a table that contains sets of pre-determined correction values that are used to supply different amounts of power to an electric stepper motor when the motor is operating at different speeds. Use of the correction values in the table allows power to be supplied to the motor in differing amounts that are approximately the same as the power actually required by the motor at different motor speeds or ranges of speeds.

Abstract: Disclosed is a method for reducing the burning of the phosphor of cathode ray tube (CRT) monitor screens used in television systems where necessary textual information is constantly displayed over a video image on the CRT screen. The method involves periodically changing the location of the textual information overlaid onto the video image without altering the information itself so that the information is continuously available, but does not remain in the same place for a prolonged time period which might otherwise burn into the phosphor of the CRT screen. The textual information may be moved as frequently as once per hour to as seldom as once every week or more; and may be move as little as one pixel to as much as several character positions. It is preferred that timing and location of movement of the textual information not be annoying to the user, and that the textual information be positioned discretely on the CRT screen in order to avoid blockage of the underlying video image as much as possible.

Abstract: A tool for designing the conductors into a PWB includes an audit arrangement for auditing or analyzing crosstalk between electrical conductors to be entered into the PWB. This crosstalk audit may be performed as soon as the initial design is created and before actual manufacture of the PWB. It is operative to identify crosstalk problem areas and to identify impedance mismatches. In particular the audit process defines conduction paths into conduction nets conduction nets are selected one at a time for evaluation and simulated as having an idle current condition. Nearby conduction nets are simulated as being driven in an active condition. The response of the idle network is used to derive a plurality of crosstalk parameters which are used to determine the crosstalk effect on the net under test.

Abstract: An improved system for performing call and return operations in a computer system in which every call and return operation changes the program counter and the frame pointer but some call and return operations change other state. Included in the state which may change in the computer system of the present invention is addresses used in calculating other addresses, an identifier specifying which instruction set the processor is executing, and protection state which determines what data may be accessed during execution of a procedure. In the system, the state saved and restored in the call and return operations is divided into basic state saved and restored on every call and return and extended state saved and restored on only some calls and returns. The frame associated with an execution accordingly contains either saved basic state or saved basic state and saved extended state.

Abstract: A multi-facetted translucent ball surrounds a lamp which is suspended from an earring clip by a flexible tubular metal shaft which has a wire running there through. The earring clip is U-shaped and has a pair of opposed legs which are spread resiliently apart when the clip is engaged on ear with the lobe between the legs. One leg carries, connected to the wire, a cup for holding a wafer battery. A U-shaped support secured to the clip carries a contact opposite the cup in a position so that the cup is urged toward the contact for engaging opposite terminals of the battery upon spreading of the clip.
