    摘要: The present invention provides a method and system for providing a light source in an optical network. The method includes providing a multiple-wavelength light, and filtering the multiple-wavelength light into a plurality of separated wavelength bands for a plurality of channels. In the preferred embodiment, each of the separated wavelength bands is substantially centered about the wavelength of a respective one of a plurality of optical channels. The plurality of separated wavelength bands is stabilized and then provided to the optical network. The light source in accordance with the method and system of the present invention is designed to only output wavelengths that correspond to optical transmission channels while eliminating the rest. It suppresses possible mode hopping, thus maintaining the power stability of all channels. Since multiple wavelengths are provided in a single light source, the number of light sources required to service a network can be dramatically reduced, increasing efficiency and reducing the cost of equipment and time for maintenance as well.

    摘要: A battery charger with a fixed frequency charging signal at or near the resonant frequency of the battery to be charged is presented. The present invention utilizes a microprocessor to modulate a current source at or near the resonant frequency of the battery to be charged without the use of a PLL. To simplify conventional modulated battery chargers, the PLL or other methods of phase correction are removed, reducing most of the calculation requirements for adjusting the phase angle, thereby reducing the piece count and ultimately cost and complexity. The result is a solution wherein charging occurs at or near the resonant frequency of the battery, and although suboptimal, the results are superior to traditional charging methods.

    摘要: A signature connector adapter adapted to provide additional capabilities for a battery charger beyond not only charge batteries, but performing other user-friendly functions is presented. One embodiment utilizes a resistor disposed within a signature charger adapter to detect battery type and communicate the battery type to the battery charger. The signature connector adapter provides information such as, but not limited to, battery chemistry, battery voltage, charging capabilities, and thermal limits. The battery charger can then optimize charging performance. The signature connector adapter allows a plurality of household, construction, medical and military devices to be charged and/or powered via the battery charger. Devices such as lights, radios, cigarette lighters, and other such devices requiring specific levels or types of power can now be operated and charged with a single charger, since the signature connector adapter facilitates the charging system changing its output to match the device's requirements.

    摘要: A method and apparatus for acquiring battery temperature measurements using stereographic thermal imaging sensors or a simple single thermal imaging sensor which can detect increases in battery heat within the field of view of any single thermal sensor, or any combination of a plurality of thermal imaging sensors is presented. Infrared Detection (ID) using the thermal imaging sensor (pyrometer) is used to focus on certain parts of a housing thereby providing an ability to “see through” or “partially see through” the battery housing to battery cells enclosed by the battery housing. Advantageously, this affords the unique capability of measuring the battery temperature before heat propagates from an individual battery cell or a plurality of battery cells to the battery housing, allowing faster heat gradient detection. Moreover, universality of battery temperature monitoring is achieved by elimination of proprietary communication between the manufacturer of the battery and the charger.

    摘要: A method and system for restoration of a fiber communication network through optical tributary switching. Multi-port optical cross-switches switch traffic at the tributary side of lightwave terminal equipment in the event of a network failure. Optical tributary switching is implemented in a variety of all-optical core network architectures including separate disjoint path, link-based mesh, and path-based mesh configurations. Network resiliency is enhanced without introducing loss over a high-speed fiber line or trunk.

    摘要: A method and system for detecting optical faults by tapping a portion of a data signal from along a fiber network link at an optical switching site or node. The tapped data signal is evaluated to determine whether an optical fault exists along the fiber link. In this way, optical faults such as a fiber failure, cable cut, or nodal LTE failure occurring within a network path, are isolated to a specific fiber span or link. Network switch controllers can then take full advantage of optical switches provided between spans in an all-optical core network to restore end-to-end path communication. In one embodiment, a presence detector simply evaluates the magnitude of the tapped signal to determine an optical fault. In a second embodiment, a protocol analyzer evaluates selected bits or fields of the protocol used in the tapped data signal to determine an optical fault. Finally, in a third embodiment, a sub-carrier modulation signal is added to the high rate data signal prior to transport over the link. The subcarrier signal is significantly lower in both frequency and amplitude than the main data signal so as to not impact reliable reception of the main data signal. A low-pass filter tuned to the sub-carrier modulation signal filters the tapped data signal. By detecting the sub-carrier signal, fault can be determined inexpensively and reliably in the presence of optical noise.
