Abstract: The present invention provides devices and methods for holding and guiding nails. The nail guide devices comprise a flexible polymer foam body having one or more slits for inserting a nail. The foam body may additionally comprise one or more adhesive layers for temporarily bonding the device to a finger or to the surface of a workpiece. Methods are provided to utilize the nail guides of the current invention for seating and driving a nail into a workpiece.

Abstract: The present invention provides for electrical devices and methods for evaluating athletic performance. A shock sensor is attached to an athlete or a suitable target such as a punching bag. When the athlete subjects the shock sensor to a shock with a magnitude which equals or exceeds the shock sensor sensitivity, an electrical effect is generated which is processed by a control means. The control means can be programmed for a delay period which precedes the performance evaluating cycle. The athlete's reaction time and shock magnitude can be measured and displayed. The devices and methods are suitable for evaluating athletic performance even if the athlete does not contact a target or an another object such as in simulated martial arts combat wherein there is no body contact between the athletes.

Abstract: The present invention provides devices and methods for drying the inside surfaces of gloves. The glove drying devices include a perforated hollow drying form in the shape of a hand. A tube is mounted to the inside of the drying form in order to improve the air flow into the interior of the form. A heating means is provided for mounting inside the tube in order to heat the air which flows into the drying form and to enhance the air flow.

Abstract: The present invention provides for circle cutters to cut drywall. The circle cutters include a removable pivoting member, a beam and a cutting member. The beam has a groove with teeth in the bottom as well as a slot. The pivoting member includes a surface having teeth for interlocking with the groove teeth. Additionally, one or more contact protrusions can be provided on the bottom surface of the beam for improved circle cutting on textured drywall surfaces.

Abstract: The present invention provides for cutting devices used in conjunction with a flexible measuring tape to cut drywall. The end segment and angled tab of the measuring tape are retained between two body components of a unit having an extended knife blade. Optionally, a guide unit is provided for attachment to the measuring tape in order to guide the cutting device in the preparation of cuts of uniform width and sufficient cutting depth to break the sheet along the cut.

Abstract: The present invention provides novel lifting devices and methods for lifting foundations and slabs. One or more power cylinders is pivotally linked to a pier and to a foundation bracket assembly. The pivotal linkage results in self-alignment between the longitudinal axis of the pier and the axis along which compressive pressure is applied to the pier.

Abstract: The present invention provides for automobile sunshields covering the roof and window areas. The sunshield has small apertures to release wind pressure from the inside of the sunshield. The sunshield is fastened onto the automobile body with suction cups. A security band and lock secure the sunshield to the automobile.
