    摘要： An optical receiver with an enhanced power capability and wide bandwidth is implemented by distributing a number of photodetectors along an optical transmission channel to convert respective portions of an optical signal into electrical signals. An electrical transmission line receives and accumulates signal inputs from the photodetectors. A velocity matching is established between the optical and electrical signals, allowing the photodetector outputs to accumulate coherently along the electrical transmission line, by loading the transmission line with distributed capacitance elements. The loading capacitances are preferably inherent in the photodetectors, which are designed and spaced apart from each other to yield the desired velocity matching. Possible photodetectors include p-i-n photodiodes with associated depletion layer capacitances, and metal-semiconductor-metal devices in which the capacitance is provided by interdigitated fingers that extend over an active optically absorbing layer on the waveguide from electrodes on either side.

    摘要： Described herein are devices, systems and methods for utilizing fluid cooling to thermally manage electrically-powered devices. Embodiments incorporating features of the present disclosure can purge heated cooling fluid from the system immediately after if has been used to absorb heat from an electrically-powered device, so that other devices in the system do not receive cooling fluid from another device in the system. In some embodiments, cooling fluid can be made to directly impinge on or near an electrically-powered device.

    摘要： Motorized hub assemblies for use with platforms and the corresponding motorized platforms are presented. At least one of the hub assemblies can be a motor and can contain an internal motor to propel the platform when activated. In some embodiments, the motorized platform has two sets of motorized wheels or two sets or motorized treads for differential rate maneuvering. In some embodiments, different base platforms are mounted to a single set of wheels or a single tread to provide a sporty style ride. A handlebar can also be implemented for greater stability. In all cases, there is no requirement for an electronic stabilization platform.

    摘要： A transparent elastomeric mold 30 capable of precisely reconstituting the buffer coating surrounding an optical fiber 54. The inventive elastomeric mold 30 is disposed to shape a buffer coating applied to an optical fiber in accordance with the dimensions of a master fiber 32. The mold 30 includes an elastomeric slab 38 for substantially confining the buffer coating within a channel 48 having a cross-sectional dimension substantially identical to that of the master fiber 32. The slab 38 includes an inner surface 50 which defines the channel 48 along a longitudinal axis L. The inventive mold 30 may also include an arrangement of arm members 34, 36 for flexing the elastomeric slab 38 in order to open the channel along the longitudinal axis L.

    摘要： A diffraction limited working beam at a given frequency is amplified without degrading its diffraction limited quality by diverting a minor portion of the beam as a probe beam, and amplifying the remaining portion of the working beam with a high power pump beam at a different wavelength. The amplification takes place in a host medium that has a rare earth dopant with an energy transition from the pump beam's wavelength to the wavelength of the working beam. The resulting amplified working beam is non-diffraction limited. The probe beam is frequency modulated and coupled with the amplified working beam in a second host medium that also has a rare earth dopant. Energy is transferred from the amplified working beam to the modulated probe beam through a resonant energy transfer in the second host medium, producing an amplified output beam at the working beam frequency that retains the diffraction limited quality of the probe beam.

    摘要： Optical sensor has divergent light from a source, preferably from a single optical fiber, and a lens which collimates the light into a broad beam. The broad beam is acted upon and passes to another lens which focuses the beam onto a single optical fiber for detection. The beam is acted upon by reflecting off of a surface when the surface is dry or dissipating when the surface is wet, or is acted on in other ways to interrupt the beam to provide a water presence signal or the like.
