Abstract: A method of estimating the precision of an apparatus that generates a continuous stream of information. The method comprises repeated resampling of the dataset defined by the data stream for a selected time interval, or repeated sampling of a theoretical distribution fitted to a dataset defined by the data stream for a selected interval, calculating the sample estimate of the population mean for each resample, calculating the index of precision from the series of the population means thus obtained for evaluation against a benchmark such as a standard value, a specification or a contract requirement. Calculations can be done by a microprocessor and microprocessor instructions internal to the instrument or by a microprocessor and microprocessor instructions external to the instruments.

Abstract: A method of making a golf ball cover which, in order to increase the golf ball cover density, comprises adding to the cover materials which are in pelletized form nano-particles of a denser material of approximately 0.05 microns or less in size and the golf ball thus produced.

Abstract: A polar balanced putter is shown having a body made of readily castable material and having a high density material in the toe and head portions and a low density material in the center portion. Connected to the putter body by a joint bar is a hosel made from a high strength light weight material.

Abstract: A cutting blade made of surgical stainless steel with a very small angled back hone, a small grind angle, a small angled front hone, and a reduced size included angle, which has an increased hardness that results in a longer lasting narrow edge geometry blade that has a reasonable cost with increased durability and accuracy, providing greater cutting precision, productivity and net yields, while reducing the compression of the blade and processing downtime.

Abstract: A combination cylinder and pistons wherein the pistons are provided with piston rods coaxially located in the cylinder so that fluid under pressure may be introduced into the head of one of the pistons at one end of the cylinder and transmitted through a tubular opening coaxial with said piston rod to the space above the head of the next adjoining piston and if desired, through similar openings in a plurality of additional pistons, until the last piston rod which is not provided with such an opening therethrough and which is connected to a tool.

Abstract: A wood-type golf club head is provided with vertical grooves adjacent at each end of the ball hitting surface in order to enhance the desired gear effect when balls are hit on the toe and heel of the club.

Abstract: A belt having rechargeable batteries thereon and connected to a light to be worn on the cap of the hunter as well as a flood light to be carried by the hunter and also a third light which may be used to illuminate the walking area. The first two lights provide different levels of illumination.

Abstract: A combination sleeping pad and backpack which may be used as a sleeping pad that when assembled and fastened together, portions of the pad function as a backpack.

Abstract: A stent retrieval device for insertion in an artery and capable of being guided along a radiopaque wire is described. The stent retrieval device includes a plurality of flexible individual fingers housed in a flexible tube with the fingers normally biased toward the interior surface of the tube so that when they are pushed out of the tube they will expand the artery and then grasp the stent to be removed.

Abstract: A golf club head made by brazing certain ceramic materials to certain metals by utilizing brazing alloys so as to provide, upon cooling, a compressively loaded component of the golf club head. The certain ceramic materials are joined to the certain metals by a brazing alloy.
