Abstract: A method for designing a system on a target device utilizing field programmable gate arrays (FPGAs) includes placing new logic elements (LEs) at preferred locations on a layout of an existing system. Illegalities in placement of the new LEs are resolved.

Abstract: A method for positioning components of a system onto a target device utilizing programmable logic devices (PLDs) is disclosed. A first location on the target device for a first logic region having a first component is determined. Determined properties of the first logic region are preserved. The first logic region is integrated with a second logic region having a second component in view of the determined properties.

Abstract: A method for designing a system on a target device utilizing programmable logic devices (PLDs) includes generating options for utilizing resources on the PLDs in response to user specified constraints. The options for utilizing the resources on the PLDs are refined independent of the user specified constraints.

Abstract: A method for positioning components of a system onto a target device utilizing programmable logic devices (PLDs) is disclosed. A location is determined for a user defined region on the target device that allows the system to satisfy timing constraints.

Abstract: A yo-yo includes a yo-yo body having first and second halves joined together with an axle. A string is interconnected at one end to the axle and at the opposite end to a solid body. Tricks may be executed using the yo-yo, including selectively releasing the solid body, supporting the yo-yo by the string at a point on the string between the solid body and the yo-yo body, and throwing the yo-yo body and solid body in the air and catching the solid body.

Abstract: A cigarette packing apparatus comprising means for repetitively progressing labels through a print location, a signal generator configured to generate a signal indicative of presence of the label as it passes adjacent the print location, a second signal generator configured to generate a signal indicative of a speed at the print location; a fluid jet printer head adjacent the print location and a controller configured to operate the printer head responsively to the first and second signal generators, with an additional arrangement within the packing apparatus defining a contact-free path portion sufficient for ink to dry at the indicia-bearing portion of the label as the label is progressed beyond the print location.

Abstract: A cigarette cartoner apparatus comprising a folding station configured to wrap a carton blank about a pre-arranged bundle of cigarette packets; means for repetitively dispensing carton blanks along a pathway; a signal generator adjacent a print location along the aforementioned pathway; at least one fluid jet print head adjacent the print location; a controller configured to operate the print head responsively to the signal generator; and a guide arrangement within the cartoner defining a contact-free path portion as the packaging material is progressed from said print location.

Abstract: Both an apparatus and method for accurately inspecting the profile of the inner wall of a conduit, such as a heat exchanger tube in a steam generator, is disclosed herein. The apparatus comprises a cylindrical probe body that is insertable within the tube, a probe assembly disposed within the probe body that includes an eddy current sensing coil and a copper plate which are movable with respect to one another, and a wall follower assembly including a stylus on one end and which is linked to the probe assembly on its other end for converting changes in the radius of the tube wall into changes in the distance between the eddy current sensing coil and the copper plate. A ferrite core is disposed within the sensing coil for focusing the electromagnetic flux into the copper plate. Additionally, the sensing coil is serially connected to a balancing coil in order to provide an accurate zero point for the sensing coil.

Abstract: A target is shaped in the form of an animate object, preferably, simulating an animal. The target is formed from any suitable material which can receive a projectile impacting thereagainst. The target is provided with a torso opening in which is emplaced a graphic representation of the internal organs of the animal so simulated. The present target is particularly adapted for use in archery.
