Abstract: An adjustable string tree provides selectable adjustment for tension on a stringed musical instrument. A back plate is fixed to a base plate, which in turn is fixed to the musical instrument. A top plate adjustably and slidably engages the back plate in order to exert tension on a string. Adjustment may be provided by an adjustment bolt in opposition to a compression spring. In a preferred embodiment, an indentation is provided in the top plate in alignment with the string to better hold the string in association with the top plate.

Abstract: An improved lighting apparatus, suitable for use as part of a lighting fixture, is disclosed, having a plurality of groups of distinct light-emitting devices, e.g., light-emitting diodes, that can be controlled to produce a beam of light having a wide variety of complex luminous flux spectra, including, but not limited, to spectra that closely emulate that of any one of a number of conventional light sources, with or without a conventional chemical dye filter. Each group of light-emitting devices is configured to emit light having a distinct luminous flux spectrum. A controller supplies selected amounts of electrical power to two or more groups of the plurality of groups of light-emitting devices, such that the groups cooperate to produce a composite beam of light having a selected luminous flux spectrum. The spectrum can be controlled to have a normalized mean deviation across the visible spectrum, relative to that of a beam of light to be emulated, of less than about 30%.

Abstract: An optical-quality part such as an ophthalmic lens is provided having a PET polarizing film integrally bonded thereto and, optionally, a hard coating integrally bonded to either the PET polarizing film or to the optical construct containing the PET polarizing film. In a preferred construction, the lens material or film may be surface treated, either physically and/or chemically, for integrally bonding the film to the lens material. Similarly, in another preferred construction, the film may be physically and/or chemically surface treated for integrally bonding a hard coating to the PET film.

Abstract: A multi-plane headstock provides different planes to which strings of a stringed musical instrument may be attached to control the tension on the string and the angle at which the string breaks from the plane of the strings over the fingerboard. Advantageous musical characteristics are provided to such stringed musical instruments by implementation of the multi-planed headstock of the present invention in greater selectability and adjustability of stringed musical instrument characteristics, as well as increased internal harmony of the instrument.

Abstract: A golf club head is provided having enhanced flexibility for launching a golf ball and is most advantageous for use in a wedge-type golf club. An upper portion of the body of the golf club head has a reduced stiffness while a lower portion of the body has reduced stiffness recesses located toward the heel and toe. A low central region supports the head at impact with the golf ball. The relative stiffness in the lower portion of the club head, varying from heel to toe, combines with a top to bottom difference in stiffness to provide enhanced flexibility and selectively increased stiffness for improved performance and feel.

Abstract: An capacitor tub assembly which includes arrays of capacitor cells coupled in series and grouped into sub-packs. The capacitors within each sub-pack being electrically coupled via a unique printed circuit board (PCB) design, wherein individual PCBs cover the top and bottom ends of each sub-pack. Each sub-pack is further electrically coupled to each of the other adjacent sub-packs within the tub assembly, thereby ensuring that all the capacitor cells in the capacitor tub assembly are electrically coupled.

Abstract: A clipless pedal/cleat assembly is disclosed, having a float range that is easily and precisely adjusted. The assembly includes a pedal body and a cleat body configured to conformably mate together, and it further includes two spaced-apart engagement recesses mounted on one of the two bodies, preferably the pedal body, and a tongue assembly mounted on the other of the two bodies, thus preferably the cleat body. The tongue assembly is configured for limited rotation relative to the body on which it is mounted, about a rotation axis generally normal to the sole of the rider's shoe when the pedal body and the cleat body are mated together. The tongue assembly includes two spring-biased tongues configured for selective engagement with the two engagement recesses.
