Abstract: A high frequency data network access system includes an aggregation node comprising at least one phased array antenna and a changeable lens for the antenna to modify its sweep arc. The lenses preferably have a continuous cross section along a vertical axis. A mounting system can also be used for mounting the lens over phased array antenna. The mounting system can comprise a housing piece and a retaining ring for holding the lens over phased array antenna.

Abstract: An underwater camera housing provided with an adaptive mechanical control arrangement for use with a broad range of camera brands and models. The camera housing is preferably formed of front and rear housing sections that are molded of clear transparent plastic and arranged to be moved between an open position for mounting a camera within the housing and a closed position in which the housing provides a watertight enclosure for protecting and communicating with a camera. The housing is provided with a truncated hemispherical lens through which a camera views scenes to be photographed to reduce distortion and not foreshorten viewing angle and a flat window and optional diffuser for providing controlled artificial illumination to a scene.

Abstract: A pivoting handlebar assembly for a cycle is characterized by a pair of handlebars and a mechanical linkage system that permit the handlebars to be moved with relative ease from one to the other of a rearward outboard position and a forward inboard position while the cycle is in motion. The assembly includes means for assuring that the two handlebars will move in unison with one another relative to a central support. A trigger and cable-operated lock mechanism is provided for releasably locking the handlebars against pivotal movement.

Abstract: A wrist or forearm support for a person operating a computer input device such as a computer mouse comprising a plurality of balls and a housing for captivating the balls so that they are capable of multi-directional rotational movement. The balls protrude through an opening in the housing in position to be engaged by and support a wrist or forearm that extends over said housing, thereby facilitating multi-directional motion of the supported wrist or forearm.

Abstract: An ergonomically designed device for supporting the wrist or forearm of a person operating a computer input device such as a computer mouse, trackball, digitizing tablet, game controller or a keyboard comprises a plurality of balls, and a housing having means for rotatably captivating the balls so that they can support a wrist or forearm while facilitating multi-directional motion of the supported wrist or forearm.

Abstract: A brake assembly for a cycle is provided which comprises a pair of caliper brake arms each having a pocket for receiving a portion of a brake pad, and a brake pad unit engaged with the brake arms, the brake pad unit comprising two brake pads carried by a spring which acts against the two brake arms so as to bias those brake arms in a direction to move the brake pads away from one another and the wheel which they are intended to engage. The brake assembly is installed in a fork crown which is adapted to be attached to a steerer tube in the case of a front wheel application or to a part of a cycle frame in the case of a rear wheel application, In a front wheel application, the fork crown accommodates part of a cable-driven mechanism for operating the brake arms, whereby to effect braking of the cycle.

Abstract: A bicycle stem assembly comprising a bicycle stem having a novel ways for securing it to an unthreaded bicycle fork steerer tube, the novel means featuring a castellated bushing for pre-loading the upper bearing for the steerer tube and a clamp carried by the stem for selectively locking the stem and bushing to the steerer tube.

Abstract: A novel brake assembly is provided for a cycle. The cycle is provided with at least one portion having cavities therein, and the brake assembly includes a brake actuator mounted on the cycle, a pair of brake calipers mounted in the cavities and pivotally attached to the cycle, a caliper-actuating body, and a motion transfer assembly coupled to and movable by the brake actuator. The caliper actuating body is connected to the motion transfer assembly. The calipers are provided with with first and second arm portions, each of the first arm portions having thereon a ramp surface engaged with the body, and each of the second arm portions being configured to receive and retain a brake pad. The calipers are pivoted by the caliper-actuating body, acting on the ramp surfaces in response to movement of the motion transfer assembly, so as to move the calipers in a direction that brings the brake pads into engagement with a wheel of the cycle, so as to exert a braking force on the cycle.

Abstract: A toy assembly 10 including a ray gun 12 capable of projecting a focused beam of light 25, and an electro-mechanically actuatable target figurine 14 including a body 46, a support 48 for supporting the body of the figurine in an upright position upon a surface, a light receiver 58, a toppling mechanism 60 for causing the figurine to topple over when operated, an energy source 82 within the figurine for powering the toppling mechanism, and a control circuit 78 for initiating the operation of the toppling mechanism when the light receiver is struck by a beam of light projected by the ray gun.
