Abstract: A putter-type golf club head that, when oriented in a reference position, includes a striking wall extending in the heel to toe direction and defines a substantially planar striking face for hitting a golf ball. A central elongate member is in communication with, and extends rearward from, the striking wall. An upper surface of the central elongate member includes a plurality of separate alignment elements. At least one of the plurality of alignment elements has an edge that extends substantially parallel to the striking face. The length of the parallel edge is substantially equivalent to the diameter of a golf ball.

Abstract: An apparatus for disinfecting an air space is presented. The apparatus includes a housing having a front surface, a back surface, a top surface, a bottom surface, a first end, and a second end. A light emitting diode is inside the housing and configured to emit ultraviolet radiation, at least 90% of which has a wavelength less than 280 nm, in a direction away from the housing into surrounding space. Circuits inside the housing control the light emitting diode to emit radiation at different intensity levels including zero. Motion sensors may be coupled to the circuits to turn the light emitting diode on and off and modulate the intensity of radiation that is emitted, thereby avoiding exposing occupants of the space to harmful radiation.

Abstract: A putter-type golf club head that, when oriented in a reference position, includes a striking wall extending in the heel to toe direction and defines a substantially planar striking surface for hitting a golf ball. A central elongate member is in communication with, and extends rearward from, the striking wall. An upper surface of the central elongate member includes a plurality of alignment elements. At least one of the plurality of alignment elements has a parallel visual indicator section, at least a portion of which extends substantially parallel to the striking surface. The width of the at least one of the plurality of alignment elements is substantially equivalent to the diameter of a golf ball.

Abstract: The invention generally relates to golf clubs with sound tuning features. In certain aspects, the invention provides a flanged rib structure configured to provide improved sound tuning characteristics for a golf club head, particularly a hollow-bodied golf club head. In one embodiment, the rib includes a web portion extending from an internal surface of the club head body and a flange portion coupled to a top surface of the web portion. The inclusion of the flange portion to the web portion increases the overall stiffness of the rib, thereby resulting in an increase in the natural vibration frequency of the club head so as to provide a more appealing sound and/or feel upon ball impact, thereby improving the overall sound characteristics of the club head.

Abstract: According to the invention, there is provided seed and plants of the corn variety designated CV789291. The invention thus relates to the plants, seeds and tissue cultures of the variety CV789291, and to methods for producing a corn plant produced by crossing a corn plant of variety CV789291 with itself or with another corn plant, such as a plant of another variety. The invention further relates to corn seeds and plants produced by crossing plants of variety CV789291 with plants of another variety, such as another inbred line. The invention further relates to the inbred and hybrid genetic complements of plants of variety CV789291.

Abstract: The present invention relates to the field of plant breeding. More specifically, the present invention includes a method of using haploid plants for genetic mapping of traits of interest such as disease resistance. Further, the invention includes a method for breeding corn plants containing quantitative trait loci (QTL) that are associated with resistance to Gray Leaf Spot (GLS), a fungal disease associated with Cercospora spp. The invention further includes a method for breeding corn plants containing QTL that are associated with Goss' Wilt, a bacterial disease associated with Clavibacter michiganense spp.

Abstract: An isolated nucleic acid fragment encoding a plastidic phosphoglucomutase protein is disclosed. Also disclosed is the construction of a chimeric gene encoding all or a substantial portion of the plastidic phosphoglucomutase, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the plastidic phosphoglucomutase in a transformed host cell.
