Patent EP-0689264-A2 (EP)
Inventor: NYGREN EVERT C
IPC: H01Q21/06
Filed: 1995-02-16
Abstract: An antenna has one feed (28) for an S-band electromagnetic signal, and a second feed (30) constructed as an array of radiators to service two C-band signal channels. A subreflector (26) having a microwave frequency selective surface (FSS) is placed in front of a main reflector (24). The C-band feed is constructed of an array of square aperture horns joined by separate transmit and receive barline beam-forming networks, and a meanderline polarizer to produce circularly polarized radiation patterns. Tapered ridges extend longitudinally along inner wall surfaces of each of the horns to provide increased bandwidth to the C-band feed. The frequency selective surface is constructed, typically, of a generally planar substrate of material transparent to electromagnetic radiation, and numerous metallic, generally annular, radiating elements, or resonators, arranged on the substrate in an array of repeating nested sets of the radiating elements. The lower frequency S-band feed is located behind and to the side of the subreflector for transmission of radiation via a folded optical path to the main reflector. The C-band feed is located in front of and to the side of the subreflector for transmission of radiation along a straight path through the FSS to the main reflector. The locating of the two feeds to the side of the subreflector permits the subreflector to be stowed by folding down upon the C-band feed, and the main reflector to be stowed by folding down upon both the S-band feed and the stowed subreflector.

Abstract: The optical fiber connector is characterized by a cylindrical and ceramic ferrule having a center-axial bore of inner diameter allowing for concentrical insertion of an optical fiber depending upon outer diameter of said optical fiber deprived of its covering layer, and having outer surface coaxial with said center-axial bore, said ferrule being fixed in the connector body of said connector so as to project from said connector body by a predetermined length. Positioning between optical fiber coaxially held in ferrule and corresponding lens unit becomes easier, thereby to have high-power laser beams positively focused on the end surface of the optical fiber and to prevent burning damages of components of the optical fiber connector. Further, once the positioning between lens units and optical fiber has been carried out, any later positioning can be omitted.

Abstract: A connector (20) for electrically interconnecting a lead of a device to a terminal spaced at a distance from the lead. The apparatus includes a conductive element comprising a first contact (32), a shoulder (34) and a second contact (36). The first contact is attached to the shoulder and extends upward therefrom, and the second contact is attached to the shoulder and extends downward therefrom. The first contact is electrically coupled to the lead of the device when the lead of the device is brought into engagement with the first contact. The second contact is electrically coupled to the terminal. A support member is positioned below the shoulder of the conductive element and a resilient biasing means (28) comprising an elastomeric material is positioned between the shoulder of the conductive element and the support member. The resilient biasing means resiliently biases the conductive element in an original position. When a downward force is applied to the conductive element, however, the resilient biasing means may be overcome thereby allowing the conductive element to move in a downward direction in response to the downward force. The resilient biasing means returns the conductive element to the original position when the downward force is removed.

Abstract: A system and method for selectively controlling database access by providing a system and method that allows a network administrator or manager to restrict specific system users from accessing information from certain public or otherwise uncontrolled databases (i.e., the WWW and the Internet). The invention employs a relational database to determine access rights, and this database may be readily updated and modified by an administrator. Within this relational database specific resource identifiers (i.e., URLs) are classified as being in a particular access group. The relational database is arranged so that for each user of the system a request for a particular resource will only be passed on from the local network to a server providing a link to the public/uncontrolled database if the resource identifier is in an access group for which the user has been assigned specific permissions by an administrator. In one preferred embodiment, the invention is implemented as part of a proxy server within the user's local network.

Abstract: In an encoding apparatus having a memory of diminished size for lowering the production cost, the memory stores input video signals made up of plural pictures including intra-pictures (I-pictures) and a scene change detector 101 detects change points of the input video signals. An encoding unit 106 encodes pictures stored in the memory 102 by fixed length encoding for generating a bitstream. A timing control unit 105 determines successive groups of pictures, each including at least an intra-picture, on the basis of the detection by the scene change detector 101, and controls the processing timing of fixed length encoding of each picture in the group of pictures by the encoding unit 106. A rate control unit 107 sets a range from a picture next to an intra-picture to the next intra-picture as a range of the code generation rate in the encoding unit 106. The rate control unit 107 controls the range of the code generation rate so that, if a scene change has been detected, the amount of the encoding information previously allocated to the intra-picture will be allocated to other pictures.

Abstract: In a printing apparatus which performs printing operation in an emulation mode designated by a host computer, data necessary for the designated emulation mode is down-loaded. First, a fixed data buffer size is reserved in accordance with the emulation mode which requires the maximum amount of data to be down-loaded. Then, a ring buffer for receiving data is assigned next to the fixed data buffer. After the data size to be down loaded is determined, portions of area reserved for the fixed data buffer which becomes unnecessary is reassigned as print data buffer. Since the print data buffer is a ring buffer, if no received data is stored at an address which is at the border between the fixed data buffer and the print data buffer, it is possible to move the border. Therefore, the printing apparatus waits until a state of the print data buffer changes to a state in which no received data is stored at the address at the border, then expands the print data ring buffer.
