Abstract: A diagnostic system includes a remote unit configured to gather information and a base unit configured to process the gathered information. A cable couples the remote unit to the base unit and is configured to carry the information. The cable includes one or more electrical conductors for communicating electrical signals between the base unit and the remote unit. The cable also includes one or more optical fibers over which the gathered information is communicated. An outside sleeve is formed around the one or more electrical conductors and the one or more optical fibers.

Abstract: Optical probes may be used to capture images of a subject. An optical probe may include an optical reflector, an optical waveguide, and an electric motor. A rotor of the electric motor is mechanically coupled with the optical reflector to rotate the optical reflector in response to an input electric current. The optical waveguide is optically coupled with the optical reflector. The optical waveguide may output light to the optical reflector which directs the light to the subject. Light may then reflect back from the subject to the optical reflector which directs the reflected light from the subject to the optical waveguide.

Abstract: A cable for coupling a base unit to a remote unit for communicating signals between the base unit to the remote unit includes one or more electrical conductors for communicating electrical signals between the base unit and the remote unit. The cable also includes one or more optical fibers for communicating optical signals between the base unit and the remote unit. An outside jacket is formed around the one or more electrical conductors and that one or more optical fibers.

Abstract: A system is disclosed. The system includes an optical waveguide; and an optical transmitter coupled to the optical waveguide. The transmitter includes a optical relay to condition a launch of an optical beam into the optical waveguide to minimize a number of optical modes launched into the optical waveguide.

Abstract: Briefly, in accordance with one or more embodiments, optical transceiver module includes a first equalizer disposed internal to the optical transceiver module that is capable of equalizing an electrical signal provided to a host board in combination with a second equalizer disposed on the host board in a split equalization type arrangement.

Abstract: Optical transponders incorporating an optical dispersion compensator (“ODC”) to perform an adjustable, frequency dependent correction of an optical signal are described and claimed. The ODC is adjusted by a feedback controller that responds to information from at least one signal analyzer. Systems using similar ODC-equipped optical transponders are also described and claimed.

Abstract: In embodiments of the present invention, an optical device tester performs stressed eye testing on several optical receivers and transmission and dispersion penalty testing on optical transmitters at a variety of data rates wavelengths using single mode optical signals and multimode optical signals using a variety of supply voltages and temperatures.

Abstract: An opto-electronic module may be provided with an internal thermoelectric cooler. Components to be cooled may be positioned over the thermoelectric cooler. Other components may be positioned aside the cooled components but raised, using a riser, to position them away from the cooled components.

Abstract: Twistlocks of a container spreader are operated and controlled by hydraulic cylinders and interlock valves connected in series. Interlock valves block the flow of fluid through the cylinders when insertion of the twistlocks in their mating connectors is incomplete. Parallel fluid ports at the inlet and outlet of the cylinders permit the inlet and outlet to be connected, at the ends of the hydraulic cylinder's piston stroke, to compensate for different volume requirements of the hydraulic cylinders.
