Abstract: An aspect of the disclosure provides for an optical-phased array (OPA) comprising a star coupler coupled to a plurality of grating couplers, wherein the star coupler comprises multiple inputs and multiple outputs. In some embodiments, each output of the star coupler is coupled to a grating coupler of the plurality of grating couplers. In some embodiments, the star coupler is coupled to the plurality of grating couplers by a plurality of optical delay lines. In some embodiments each output of the star coupler is coupled to a grating coupler of the plurality of grating couplers via an optical delay line of the plurality of optical delay lines. In some embodiments, the OPA further includes an optical switch coupled to the multiple inputs of the star coupler, and at least one tunable laser. Another aspect of the disclosure provides a method for steering light using the OPA.

Abstract: A saw (10) facilitates cutting of roofing and includes a frame (12) that is mobile on a work surface. A locking mechanism (40) locks the frame (12) into a transport position. Actuating a release lever (60) allows the frame (12) to be adjusted into a working position. A shaft (14) rotatably mounted by first, second and third bearings (74, 75, 76) has saw blades (16, 18) and a pulley (77) for connection with a drive belt (80). The drive belt (80) passes through a hole (79) in the frame (12) to connect to a drive (81) to rotate the shaft (14) and the saw blades (16, 18). The third bearing (76) is mounted to a bearing support (85). The frame (12) has a gap (84) communicating the hole (79) with an exterior edge (78) of the frame (12) proximate the third bearing (76), with the bearing support (85) removably and replaceably mounted to the frame (12) and spanning the gap (84).

Abstract: An elongated member, for example, a bowling pin, has a core of foamed plastic material, which has areas of greater density, generally toward the lower end of the bowling pin, so as to provide desired weight distribution along the member. In the bowling pin, providing a denser core area near the bottom lowers the center of gravity. In a baseball bat, the increased density can be provided in the "sweet spot" area, if desired.In producing the variation in density, the mold in which the foamed core is formed is heated in those areas in which the density is to be light and chilled in those areas in which the density is to be increased.In making a baseball or softball bat, a foamed core can be wrapped directly with graphite filament or graphite and glass filaments, or synthetic fibers such as Aramid fibers of the type marketed by Dupont de Nemours as KEVLAR.RTM. either dry wrapped and subsequently embedded in epoxy or the like, or wrapped with adhesive coated fiber that is then cured.
