Abstract: A breakaway coupler includes a main body and a secondary body, removably attached to the main body. First and second attachment features are formed on the main and secondary bodies to permit attachment to first and second structures. A breakaway member connects the main and secondary bodies. A guide channel passes through an overlapped portion of the main and secondary bodies and accepts a cable therein. A blade passes across the guide channel to sever the cable when the secondary body is detached from the main body. In operation, a cable clamp frictionally holds the cable. The cable clamp is connected to the breakaway coupler, which is in turn connected to a fixed structure, e.g., a pole. When an excess force is applied to the cable, the main and secondary bodies of the breakaway coupler separate and the blade cuts the cable in the guide channel.

Abstract: An alignment sleeve for an optical fiber adapter includes features to bring precision alignment between optical fiber cores. The sleeve includes a tubular inner area to accept first and second ferrule ends of first and second connectors. First and second tabs project from first and second ends of the sleeve. The first and second tabs slide into holes in the ferrule holders or barrels of the first and second connectors, so as to provide rotational alignment of the first and second ferrules, which may be presenting multi-core optical fibers. A mid-portion of the sleeve may include geometrical features to enable a snap fit of the sleeve into a housing of the adapter. More than one tab may be employed at the ends of the sleeve, and the tabs may have defined spacing and/or dimensions to enable security keying, only permitting coupling between connectors possessing matching holes in the ferrule barrels.

Abstract: An expanded beam fiber optic array connector includes a ferrule holding ends of optical fibers in a first ordered array. A plurality of lenses packaged into a unitary structure, formed of an optical grade material, different than a material used to form the ferrule, is attached to the ferrule. The lenses are arranged into a second ordered array matching the first ordered array of the ends of the optical fibers. The lenses of the expanded beam connector associated with transmit channels can be constructed with a prescription geared specifically for transmitting light, whereas the lenses of the expanded beam connector associated with receive channels can be constructed with a prescription geared specifically for receiving light.

Abstract: An oil cooler for a motorcycle includes a heat exchanger residing within a primary drive between an engine pulley and a clutch pulley. A fan within the primary drive pushes or pulls air through the heat exchanger. The fan may be electrically or mechanically operated and mounted to one of a base plate or a cover plate of the primary drive. Alternatively, the fan may be formed as a mechanical portion of one of the primary drive components. Vectoring blades may assist in directing an air flow within the primary drive to the heat exchanger, and vents may be formed in the cover plate for air intake and/or exhaust.

Abstract: An attenuator for optical signals includes a base. A first ferrule has a first optic fiber passing through a central bore therein and attached to a first lens at an end of the first ferrule. The first ferrule is fixed in position relative to the base. A second ferrule has a second optic fiber passing through a central bore therein and attached to a second lens at an end of the second ferrule. The second lens faces the first lens. The second ferrule is fixed to the base and can be moved relative to the base by a user adjustment feature, so that the second lens may be moved relative to the first lens. The relative placement between the first and second lens controls the attenuation of the attenuator.
