Abstract: A modulated optical signal processing method and apparatus optically convert an optical signal to an intermediate frequency band that simplifies electrical processing after optical detection, thereby increasing the optical reception sensitivity. Either single-mode light is modulated with a first radio wave overlaid with data, or a modulated optical signal is directly generated, and the optical carrier and optical sideband contained in that modulated optical signal are transmitted, the transmitted optical carrier and optical sideband are input and the input optical carrier and optical sideband are mixed with a radio wave of a predetermined frequency and a combination of an adjacent optical carrier and optical sideband that are closer together than the frequency of the first radiofrequency electrical signal is optically selected from among a frequency-converted or frequency-unconverted optical carrier and optical sideband thus obtained and an electrical signal is detected from this selected optical signal.

Abstract: An open architecture platform bypasses data from the facilities of a telecommunications carrier, e.g. an incumbent local exchange carrier, by distinguishing between voice and data traffic, and handling voice and data traffic separately. An SS7 gateway receives and transmits SS7 signaling messages with the platform. When signaling for a call arrives, the SS7 gateway informs a control server on the platform. The control server manages the platform resources, including the SS7 gateway, tandem network access servers (NASs) and modem NASs. A tandem NAS receives the call over bearer channels. The control server determines whether the incoming call is voice traffic or data traffic, by the dialed number, and instructs the tandem NAS how to handle the call. Voiced traffic is transmitted to a switch for transmission from the platform. Data traffic is terminated at a modem NAS, where it is converted into a form suitable for a data network, such as a private data network or an Internet services provider (ISP).

Abstract: A reverse caching system monitors residential end-user communications to cache content files when they are transferred from the residential end-users over access links to a core communication network. The reverse caching system monitors the residential end-user communications to identify requests for the content files cached in the reverse caching system. In response to identifying the requests, the reverse caching system transfers the requested content files from the reverse caching system to the core communication network.

Abstract: A hard disk stores a CAD file having 3-D data that relates to an assembly product comprised of a plurality of parts. Based on this 3-D data of an assembly product, a parts data retriever retrieves 3-D data for each part. According to this 3-D data for each part, a bitmap output unit generates 2-D bitmap image data illustrating the part image, which is viewed from a predetermined direction. Moreover, using the 2-D data of the part, a management data generator generates a management table describing steps to output an assembly scene on a screen. A file having this management table and a file having 2-D data are then delivered to a PC for assembly scene output, in order to output the assembly scene.

Abstract: A pluggable optical transceiver having a pivotable actuator assembly for quickly and easily removing the transceiver from a receptacle cage is provided. The actuator assembly includes a pivotable lever arm and a slide member that can slide in a forward and rearward direction. Force is first applied to the actuator lever so that it pivots and rotates to a different position. Then, as force is applied to the pivoted actuator lever, the slide member slides rearwardly causing the transceiver to become disengaged from the receptacle. In this manner, the transceiver is released and can be removed easily from the receptacle.

Abstract: A system and method for effecting wideband image rejection. In a receiver implementation, the inventive method includes the steps of receiving a first signal in a first frequency band and generating in-phase and quadrature signals therefrom. The phase of the in-phase signal is shifted to provide a second signal and the phase of the quadrature signal is shifted to provide a third signal. A predetermined phase relationship is thereby effected between the second and the third signals. The second and third signals are then summed to provide an output signal which has minimal interference from a mixing signal. In an illustrative receiver application, the phase shifting is achieved via the use of all pass networks. Each of the all pass networks include a differential amplifier having first and second input terminals. The first and the second terminals are connected to a first end of first and second resistive elements, respectively.

Abstract: Four-port optical circulators and apparatus employing such optical circulators are disclosed. The circulators utilize various arrangements of birefringent elements, polarization rotators and non-reciprocal polarization rotators to route optical signals from a first input/output (I/O) port to a second I/O port, from the second I/O port to a third I/O port, from the third I/O port to a fourth, and from the fourth I/O port to the first I/O port. The number of components and their configuration may be varied depending upon requirements of optical isolation, port configuration, manufacturability, yield and cost. Four-port circulators may be incorporated into an apparatus with optical signal conditioners, such as chirped fiber gratings, wavelength converters or optical amplifiers, optically coupled to one or more of the input/output ports. Alternatively, the circulators may be incorporated into a bidirectional add/drop apparatus with bandpass filters coupled to two of the input/output ports.

Abstract: A message processing system allows a user to create messages for delivery to a number of recipients. In addition, the user can create one or more comments or special instructions in the message that are to be delivered to fewer than all of the recipients of the common message. The comments are encrypted such that they cannot be accessed by all recipients of the message but only selected recipients of the message. The message processing system may decrypt the comments and include them along with the common portion of the message prior to delivery to those recipients that are to receive the comments. Alternatively, a recipient of a common portion of a message selects an icon or other prompt indicating that a comment is attached to the message. The recipient is asked to enter a password or other security code that causes the messaging system to determine whether the recipient is to receive a comment and if so, to decrypt the attached comment.
