Abstract: A Magnetically Attached Golf Tee (MAGT) consisting of an upper section and a lower section. The upper section has an upper concave surface that supports a golf ball and a lower flat surface that has attached an upper permanent magnet. The lower section has a lower pointed end that is inserted into the ground and an upper flat surface that has attached a lower permanent magnet. When the two magnets interface, the MAGT can be used as a conventional golf tee. When the upper section is struck by a golf club, the upper section separates from the lower section without causing damage to the MAGT. The separated upper section can be retrieved and re-attached to the lower section, allowing the MAGT to be reused numerous times.

Abstract: An electro-optical converter assembly is described. The electro-optic converter includes an optically transparent substrate with a plurality of alignment apertures and an optical device disposed on a first planar surface of the optically transparent substrate in alignment with the plurality of alignment apertures so that an axis of transmission of the optical device passes directly through the optically transparent substrate.

Abstract: A method and apparatus are provided for transmitting an optical communications signal. The method includes the steps of securing an optical device onto an optically transparent substrate with an optically transparent adhesive such that an axis of transmission of the optical device passes directly through the optically transparent adhesive and a portion of the body of the optically transparent substrate, darkening a portion of the optically transparent adhesive with a laser; and transmitting light from the optical device through the darkened portion of the optically transparent adhesive such that at least some of the light from the optical device is absorbed by the darkened portion.

Abstract: A method and apparatus are provided for aligning an optical array with a substrate. The method includes the steps of aligning the substrate with a set of alignment structures on an alignment fixture, transmitting a plurality of optical signals from the fixture through the substrate, and automatically aligning the optical array to the substrate using the transmitted plurality of optical signals and a pick and place machine.

Abstract: A method and apparatus are provided for coupling an optical signal between an optical array and a flexible optical waveguide. The method includes the steps of disposing the optical array on an optically transparent substrate with an axis of transmission of an optically active element of the optical array passing directly through a body of the substrate, aligning a set of guide pins to the optically active element of the optical array, securing the aligned guide pins to the substrate and detachably coupling the flexible optical waveguide to the guide pins so that the axis of transmission of the optically active element is aligned with an axis of transmission of the flexible optical waveguide.

Abstract: A grout delivery apparatus and method for delivering grout through a flexible conduit from a bulk supply of grout to a hand tool. The bulk supply of grout is held in a hopper which feeds the grout under gravity to a pump. The pump is driven by an electric motor which receives its electrical energy through a controller. The controller is adjustably preset to control the electric motor as a function of the individual settings on a multifunction switch operable by the worker. The switch can either be mounted on the hand tool and directly wired to the controller or incorporated into a remote transmitter which transmits the particular switch position to a receiver on the controller.
