Abstract: Tooling is held within the nose of a rotary punch and as the tool is rotated and forced against a workpiece a fastener within the tool becomes affixed to the workpiece. The tools have displacers which non-destructively deform and reshape the workpiece without any loss of workpiece material. The tools have various types of displacers including; tapered and arcuate displacers which act in concert to progressively act upon the workpiece; spherical displacers which may be fixed or rotatable such as caged ball bearings; and a full-circle displacer ring which wobbles as it presses against the workpiece. In the case of fixed spherical displacers, a multi-stroke method can be employed where the tool is rotated after each stroke in a group of installation strokes.

Abstract: This application relates to hidden fasteners within an electronic device. An electronic device can include a top portion and a base portion that includes a housing and a cover attached to the housing by at least one fastener that is not visible through an external surface of the cover. Each fastener includes a receiver housing that retrains spherical components and a pin that can be inserted into an opening in the receiver housing. The pin is retained in the receiver housing by a force imparted against a surface of the pin by the spherical components, which are biased towards an inner surface of the receiver housing sloped towards the opening. The pin can be released when an external magnetic field from a magnet placed proximate the bottom surface of the receiver housing retracts the spherical components away from the opening, thereby reducing the force against the surface of the pin.

Abstract: An aquatic seat assembly includes a seat for supporting a user and a seat support structure for attaching the seat to a wall such as a dock. The seat support structure includes an adjustment mechanism for adjusting the height of the seat relative to the wall such that the seat can be raised or lowered.

Abstract: A concrete cutting chain saw has heretofore been considered a rugged performing tool demanding high horsepower and unavailable to the homeowner having only single phase electrical power for powering such a tool. This has been addressed and resolved by a balancing of the torque and chain speed to thereby allow for sufficient torque at the lower horsepower capability of single phase power inputs. Chain width and thereby cutting width may also be reduced, as well as the abrasive elements per cutter may be reduced in order to enable the use of low horsepower power heads.

Abstract: A concrete cutting chain saw has heretofore been considered a rugged performing tool demanding high horsepower and unavailable to the homeowner having only single phase electrical power for powering such a tool. This has been addressed and resolved by the reduction of chain speed to thereby increase torque for the lower horsepower capability. Chain width and thereby cutting width is also reduced, and cutting implements per cutter are reduced, all lowering power demands and resulting in a smooth concrete cutting chain saw for homeowner use. Also included is a conversion kit for converting available homeowner power tools, e.g. an angle grinder for use as a concrete cutting chain saw.

Abstract: A method for sports training allows an athlete to move an exercise bar connected between congruent trusses freely in two dimensions. The resistance the bar offers to the movements of the user is programmable and may be varied according to predetermined parameters and also as a predetermined function of measured parameters. The parameters of the exercise may also be recorded.

Abstract: An apparatus for sports training allows an athlete to move an exercise bar freely in two dimensions by connecting the bar between congruent pantograph trusses. The resistance offered to the movements of the user is programmable and may be varied according to predetermined parameters and also as a predetermined function of measured parameters. The apparatus further incorporates means to record the parameters of the exercise.
