Abstract: An apparatus for and method of utilizing an Internet terminal coupled to the world wide web to access a legacy data base management system having a dialog-based request format using a standardized object-based command language, such as JavaScript, rather than the proprietary command language native to the legacy data base management system. This approach leverages the power of the legacy data base management without the need for the user to become familiar with the proprietary command language of the legacy data base management system. The approach is particularly efficient in that the user can provide parameters to the legacy data base management system as a parameter object.

Abstract: A system and method for hardware based reassembly of a fragmented packet is shown. The method includes receiving a bandwidth request to transfer a data packet from the data provider. Then, bandwidth is allocated to the data provider, where the allocated bandwidth is less than the requested bandwidth. Next, the present invention receives part of the data packet in the allocated bandwidth from the data provider, where the part of the data packet includes a fragment header, and the fragment header includes a sequence number for the part of the data packet. The part of the data packet is then stored in external memory. Finally, the data packet is reassembled by concatenating in the correct sequence the part of the data packet with other parts of the data packets to create the reassembled data packet.

Abstract: A termination anchor having a neck region, a mid region, and a distal region. An expanding passage through the anchor from the neck region to the distal region is bounded by an internal surface. Exposed strands on a cable are trapped within this expanding passage by infusing them with liquid potting compound (either before or after the strands are placed within the passage). This liquid potting compound solidifies while the strands are within the anchor to form a solidified potted region. The present invention optimizes the profile of the internal surface in order to transfer stress occurring in the neck region to the mid region and the distal region. By transferring some of this stress, a more uniform stress distribution and a lower peak stress are achieved.

Abstract: Downstream synchronous multichannel (DSSM) communications are provided among a plurality of carriers, each being a completely DOCSIS™ 2.0-compliant downstream. The synchronous multichannels support communications with both DSSM-capable communications nodes and non-DSSM-capable communications nodes (e.g., legacy cable modems). Non-DSSM packets are transmitted on a single channel. DSSM packets are split into multiple pieces, which are transmitted simultaneously on all available channels. Since the physical delay variation (e.g., group delay change) across the adjacent carriers is small (on the order of a symbol time), the multiple pieces arrive at the receiving communications nodes at nearly the same time and can be reassembled with minimal buffering and no packet ordering problems. To avoid causing trouble for the non-DSSM-capable communications nodes, the packet pieces are encapsulated with a header that causes the non-DSSM-capable communications nodes to silently discard them.

Abstract: A method, system, and computer program product for in-place, lightweight Ack packet promotion is provided. The method includes receiving a new Ack packet; searching through a transmit queue for an old Ack packet that corresponds to the new Ack packet; and replacing the data in a number field, a checksum field, a window size field, and a timestamp options field of the old Ack packet with data in a number field, a checksum field, a window size field, and a timestamp options field of the new Ack packet.

The modulating element has alternating first and second modulating regions circumfrentially spaced around a central axis thereof. The modulating element is displacement relative to the array of detectors so that the detector array forms a two-dimensional image of the first and second regions of the modulating element of array. A data processor is connected to the detector array and is adapted to indentify the orientation of at least two different radially extending edges of regions on the modulating element from the two-dimensional image and also to determine the position of the centre of the element from the determined orientation of the edges.

Abstract: A traffic prioritization system performs a coarse classification of upstream bursts at the physical interface of a headend communications device. The headend device monitors and controls communications with a plurality of remote communications devices throughout a widely distributed network, including the Internet. The traffic prioritization system includes a burst receiver that receives and sends the upstream bursts to a classifier. At an appropriate time, the classifier receives the upstream bursts and queries a priority lookup table (LUT) to determine a priority classification. The priority classification is used to separate the bursts into two or more priority levels. The higher priority level is used to designate services having a low tolerance for delay, such as telephony. Upon classification, the upstream bursts are forwarded to one of several priority queues. Each priority queue corresponds to at least one priority level.

Abstract: In an electric power assisted steering system, the output signal from a motor position sensor (9) comprising a number of Hall effect devices (A,B,C) or the like is combined with an index signal from a sensor (108) connected to the steering column shaft (1) or the rack (6) or a yaw sensor or other angular position dependent device to produce an accurate measure of steering angle relative to the straight ahead position. In a preferred arrangement, transitions in the Hall effect sensor output are used to drive a counter (106) which is reset whenever the index signal is produced to ensure it does not drift out over a period of time. Most conveniently, the index signal corresponds to the steering gear straight ahead position.

Abstract: An electric power assisted steering system is disclosed which comprises a steering shaft connected at one end to the handwheel and at its other end to at least one roadwheel, while an electric motor is connected to the steering a gearbox having a non-integer reduction gear ratio. Two sensors are also provided with one sensing the angular position of the motor rotor and the other sensing the angular position of the steering shaft. The presence of the non-integer gear ratio produces a beat frequency between the output of the two sensors from which an unambiguous measurement of the angular position of the steering shaft over a range of greater than one complete revolution can be made. The sensors may comprise either absolute position sensors or index-type sensors.

Abstract: An IR radiating decoy for an IR seeking anti-ship missile (ASM) includes a propulsion section, safe and arming section, gas generator section, fuel tank section, and flight stabilization section to ignite and continuously maintain an IR plume for decoying the ASM away from the targeted ship. The IR radiating decoy ignites the IR plume immediately when the decoy reaches a safe separation distance from the targeted ship. The IR plume continues to be emitted as the decoy flies away, as it lands on the water, and while it floats upon the water until all the fuel is used from the fuel tank. The fuel can be changed to change the signature of the IR plume so that different ASM missiles can be drawn away from the ship.

Abstract: An optical displacement sensor is used to measure the rotary displacement between two shafts which rotate together. By connecting the shafts together by means of a torsion bar, the sensor may be used to measure transmitted torque. The sensor comprises first and second coaxial discs mounted on the shafts and having slots formed therein. A light source directs light through the slots onto an array of photodetectors and a data processor determines the displacement or torque from the positions on the array of images of the slot edges.
