Abstract: A leaning chair can include a base defining a lower surface that rests on a floor, the base including a support surface; a shaft coupled to the base, the shaft defining a first end and a second end; a flexible mount coupling the first end of the shaft to the base, the shaft extending through the mount; a pivot pin located underneath the mount, the first end of the shaft resting on the pivot pin, and being configured to be housed inside the mount, the pivot pin being configured to pivot on the support surface; and a user support member coupled to the second end of the shaft.

Abstract: A turf groomer is coupled to a reel cutting unit in advance of the cutting reel and is powered by a gearbox having a rotary gear drive that is capable of selectively rotating the turf groomer in opposite directions at different speeds. The rotary gear drive is symmetrical about a plane through the axes of the input and output shafts thereof to permit the gearbox to be inverted to drive the turf groomer from either the left or right sides without requiring that two different models of the gear drive be available. The gearbox is connected to the reel cutting unit only by connecting the end of the input shaft to a shaft of the cutting reel and through a connection to a height adjuster for the turf groomer.

Abstract: An adjustable desk platform can include: an upper platform defining a substantially planar work surface; a base located beneath the upper platform, the base defining a bottom surface without legs that is adapted to sit on an existing desk; first and second sets of arms coupling the upper platform to the base, wherein the first and second sets of arms are adapted for movement of the upper platform substantially in parallel with the base between a fully raised position and a fully lowered position; and a user-operable locking mechanism associated with the upper platform, the locking mechanism adapted to releasably lock the upper platform in the fully raised position, and in at least one intermediate position between the fully raised position and the fully lowered position. Other features and embodiments are discussed.

Abstract: A massage mat system includes a mat having an upper surface; a track defined in the upper surface; and a ball-shaped massage roller, wherein the track is dimensioned to receive a first portion of the ball-shaped massage roller while a second portion of the ball-shaped massage roller protrudes from the track above the upper surface of the mat. The ball-shaped massage roller is rotatable along the track through contact between the second portion of the ball-shaped massage roller and a user's foot.

Abstract: The Food Smoker Adapter converts an outdoor cooking system into a meat smoker without physical modification. It is comprised of a lid, smoke chamber, meat skewers, and a wood chip pan. It can also act as a stand alone meat smoking system when used with an auxiliary electric heating element. The smoke chamber is a tube or duct, and is placed on the wood chip pan or an accessory allowing the stacking of an additional smoke chamber. The wood chip pan rests above the heat source. Skewers are placed across the top of the smoke chamber allowing meat to hang inside. The lid acts as a smoke chamber lifting mechanism, and has tabs that snap into slots near the top of the smoke chamber allowing the lid, smoke chamber, skewers, and meat to be removed and set aside allowing access to the wood chip pan for tending.

Abstract: A target assembly to produce radioisotopes for the synthesis of radiopharmaceuticals. The target assembly includes a target vessel with a target chamber adapted to receive a target material. A thin cover sheet of particle-permeable material covers the target chamber. In a bombardment process, a high-energy particle beam generated by a cyclotron or particle accelerator strikes the thin cover sheet, whereby at least some of the particles from the particle beam penetrate to the target chamber so as to interact with the target material, altering the nuclear makeup of some of the atoms in the target material to produce radioisotopes.
