Abstract: A tag communication method includes providing a tag reader operating at a first frequency and having transmit and receive antenna ports, providing a frequency converter module having transmit and receive plugs adapted to directly mate with the transmit and receive ports, and directly mating the transmit plug with the transmit port and the receive plug with the receive port. A transmit signal at the first frequency is received from the reader by the converter module by way of the directly mated transmit plug and converted to a second frequency differing from the first frequency to provide a converted transmit signal which is transmitted to the tag. A receive signal is received from the tag at the second frequency and converted to the first frequency to provide a converted receive signal which is applied by the conversion module to the reader by way of the directly mated receive plug.

Abstract: A WDM add/drop module. The drop portion of the add/drop module is accomplished by using thin film filters or thin film interleavers. The add portion of the add/drop module uses fused fiber interleavers for the less critical stages of the multiplexing process. In a final stage, fused fiber interleavers can be placed in series. A thin film intervleaver having a flattop frequency response may also be used for the critical stage where the multiplexed channels are more closely spaced. The frequency response of the thin film interleaver is relatively constant across a bandwith of a channel while having a drop off at the channel edge to reduce cross talk.

Abstract: Systems and methods provide for the addition of DWDM modules to CWDM systems in order to increase bandwidth over existing lines. This allows for the expansion of communications capacity without the need to replace existing CWDM systems. The DWDM modules can be transparently inserted into the CWDM systems by, in the CWDM system, reserving a channels for use by the DWDM. The DWDM system then occupies that channel with a scalable number of DWDM wavelength channels, for example four, eight, or sixteen. The DWDM systems can be used in both single and dual fiber systems as well as ring systems. Use of single fiber systems is obtained by implementing coupling devices, such as interleavers, passband filters, and circulators, that can used in pairs to couple bidirectional signals over a single fiber.

Abstract: A brake pad assembly is provided that includes a backing plate including a first surface, a second surface opposite to the first surface, and least one opening. Also included are a friction material associated with said backing plate and a shim plate having a first shim surface and a second shim surface, and a tab projecting from the second shim surface.

Abstract: A method and system for enabling auto shut-off of programming of a non-volatile memory cell is disclosed. The system includes a memory array having a plurality of memory cells, each cell storing one bit of data. During the programming process, programming signals are applied to the target memory cells. A predefined period of time after the programming signals are applied, the auto shut-off system begins sensing an output signal from the memory cell. After the system detects an output signal from the memory cell, the system waits for a second predefined period of time before turning off the programming voltages. The system may be configured to sense an output voltage from the memory cell. The system then compares the output voltage to a reference voltage in order to detect when the cell is programmed. Alternatively, the system may sense an output current from the memory cell. The system then compares the output current to a reference current to detect when the cell is programmed.

Abstract: A thin film interleaver device is disclosed. The thin film interleaver includes thin film optics. The thin film(s) are formed such that they reflect one group of wavelengths while allowing a second group of wavelengths to pass through the thin film(s). The thin film(s) exhibit a flat top frequency response across the channel bandwidths of the multiplexed signal for which the thin film filter is designed such that the thin film interleaver is less sensitive to wavelength drift and temperature variations.

Abstract: The present invention utilizes the main Java package (javax.jcr.binary) for saving the node property path and other relevant retrieving information within the serialized XML node files so that the intended large binary data remains inside the content repository while the corresponding node is being serialized. A data centric application which requires processing of the serialized XML node file can then deal with a much reduced sized XML file. This can improve the performance greatly in terms of memory usage and processing speed for XML processors such as DOM. During the consuming phase of the data centric applications, the binary data property is streamed from its source JCR repository into the target repository by looking up its original property path and other retrieving information.

Abstract: A compact optical isolator includes a polarizer, a Faraday rotator, and an analyzer that are arranged in series. A magnet is also included to provide a magnetic field to the Faraday rotator. The outer edges of the polarizer, Faraday rotator, and analyzer are preferably parallel to each other and to the optical path of the incoming light beam so that the optical aperture through the optical isolator is maximized. In addition, each of the polarizer, the Faraday rotator, and the analyzer have at least one facet in the optical path of the light beam that is tilted from perpendicular with respect to the light beam such that reflections are avoided. The analyzer may have a wedge shape such that one surface mates level with an optical fiber and the opposing surface is tilted to prevent reflections. Alternatively, a wedge-shaped block may be located between the analyzer and the optical fiber.

Abstract: Systems and methods use single-fiber optical add/drop multiplexers (OADMs) to enable bi-directional data transmission in WDM systems over a single fiber. By reducing the required capacity for an optical network from dual fibers to a single fiber, significant cost and bandwidth efficiencies are achieved. The systems and methods also provide redundancy protection in single-fiber bidirectional line ring systems. In the event of a downstream fiber or device failure, the OADM module receives a signal on a first wavelength from a first direction, shifts the signal from the first wavelength to a second wavelength, and sends the signal back down the fiber it originated from on the second wavelength, thus maintaining the propagation of the signal in the ring system.

Abstract: A redundant optical signal transmission and reception system is disclosed to enable information exchange via an optical communications network without data loss in the event of optical transmitter or receiver failure. In one embodiment, the redundant optical signal system includes a primary transmission link comprising a plurality of optical transmitters and a multiplexor for modulating and combining electrical signals into a primary multiplexed optical signal. In the event of failure of an optical transmitter, a backup transmission link is activated to compensate for the malfunctioning transmitter. The backup transmission link utilizes a backup optical transmitter to modulate the electric signal formerly received by the malfunctioning optical transmitter. The backup transmission link combines the backup optical signal with the primary multiplexed optical signal to form a complete optical signal for transmission over the optical network.

Abstract: This disclosure is concerned with optical add/drop modules. In one example, he drop portion of the add/drop module is accomplished by using thin film filters or thin film interleavers. The add portion of the add/drop module uses fused fiber interleavers for the less critical stages of the multiplexing process. In a final stage, fused fiber interleavers can be placed in series. A thin film interleaver having a flattop frequency response may also be used for the critical stage where the multiplexed channels are more closely spaced. The frequency response of the thin film interleaver is relatively constant across a bandwidth of a channel while having a drop off at the channel edge to reduce cross talk.

Abstract: The present invention provides low cost methods and apparatuses for filtering out polarized light reflections in a free space optical isolator. Multiple polarizers having relatively poor extinction ratios can be stacked together as polarizer assemblies having higher extinction ratios than possible with the individual components. One or more polarizer assemblies may then be used in series with an optical signal generator, an optical signal rotator, one or more other polarizers or polarizer assemblies, and a fiber optic receptacle to isolate an optical signal in a transmitter optical subassembly. Accordingly, the present invention can polarize an optical signal more efficiently than with prior methods, doing so at a relatively high perpendicular beam extinction ratio with a much lower cost.

Abstract: A reflective optical switch for use in optical systems, such as fiber optic communications networks, is disclosed. The optical switch includes not only signal transmission characteristics, but also signal reflection capability. The optical switch includes a semiconductor substrate having first and second optical signal waveguides disposed thereon. The two waveguides intersect one another at a selected angle to form an intersection region. A thermal element is disposed atop the intersection region and can be activated to alter the index of refraction of a portion of the intersection region. An optical signal passing through the intersection region is diverted from one waveguide to another according to the heating of the intersection region by the thermal element. A reflective component disposed in a terminal end of one of the waveguides reflects selected optical signals back to the source from which they came.

Abstract: Exemplary embodiments of the present invention provide for methods to launch data signals from single mode fiber optic cable into legacy multimode fiber optic cable. In one exemplary embodiment, a single mode fiber is offset slightly from the axis of a multimode fiber, thus only exciting the outer mode of the multimode fiber. In an alternate exemplary embodiment, a core portion of the single mode fiber is exposed, heated, and fused with a cladding portion of the multimode fiber. In yet another alternate exemplary embodiment, various lenses can be used to collimate and focus light signals from single mode fibers into multimode fibers, and vice versa. In these exemplary embodiments, the transmitted light signals can be in the range of from 1470 to about 1610 nm with, for example, a 20 nm channel separation. Other wavelengths and channel separations are also possible.
