Title: Method and system for managing keys for encrypted data
Inventor: KOU WEIDONG
IPC: H04L9/08
Filed: 1999-03-30
Abstract: A computer system and method manages encryption keys for data. The system and method generates a session key and encrypts given data with the session key. The system and method generates a key encryption key based on a secret initial vector, or password.  The session key is encrypted using the key encryption key. The encrypted data and the encrypted session key are then interleaved according to a set of indices created by a one-way transform. The one-way transform takes as its input the initial vector, the length of the encrypted session key and the length of the encrypted data. The data is recovered by a party knowing the initial vector using the one-way transform to determine the location of the encrypted session key in the interleaved data. The session key is decrypted which allows the data to be decrypted.

Title: Scaleable data network router
Inventor: BRUECKHEIMER SIMON DANIEL
IPC: H04L12/70
Filed: 1997-12-01
Abstract: In a broadband network comprising a plurality of edge switches interconnected by a plurality of tandem switches, IP packet data is routed by determining from each packet whether that packet forms part of a flow of packets. Where a packet is determined to be part of a flow, it is segmented into minicells for transmission over a permanent virtual channel established across the network for that flow. Where a packet is not determined to be part of a flow, a destination edge switch is identified for that packet which is then transported to that edge switch via a default permanent virtual channel. Permanent virtual channels for new flows are established at the network periphery by defining a succession of nodes and virtual channels (VCs) to be used to reach the destination of that flow.

Abstract: An improved optical photolithography system and method provides predetermined light patterns generated by a direct write system without the use of photomasks. The Direct Write System provides predetermined light patterns projected on the surface of a substrate (e.g., a wafer) by using a computer controlled means for dynamically generating the predetermined light pattern, e.g., a spatial light modulator. Image patterns are stored in a computer and through electronic control of the spatial light modulator directly illuminate the wafer to define a portion of the polymer array, rather than being defined by a pattern on a photomask. Thus, in the Direct Write System each pixel is illuminated with an optical beam of suitable intensity and the imaging (printing) of an individual feature is determined by computer control of the spatial light modulator at each photolithographic step without the use of a photomask. The Direct Write System including a spatial light modulator is particularly useful in the synthesis of DNA arrays and provides an efficient means for polymer array synthesis by using spatial light modulators to generate a predetermined light pattern that defines the image patterns of a polymer array to be deprotected.

Title: Polarization insensitive grating in a planar channel optical waveguide and method to achieve the same
Inventor: JOHNSON DERWYN C
IPC: G02B6/12
Filed: 1999-10-21
Abstract: A method is disclosed wherein optical structures such as Bragg gratings can be written into planar waveguides disposed on a substrate. By employing the method of this invention, a polarization insensitive device can be made. Such relatively thin planar waveguides disposed on a substrate are inherently polarization sensitive and the structure itself is birefringent. By writing structures in the waveguides or by simply writing a refractive index change in the waveguide by limiting the beam width at the waveguide layer to less than or equal to the thickness of the waveguiding layers on the substrate, in combination with conventional wider beam writing techniques, polarization sensitivity can be lessened or obviated.

Abstract: In an attachment method and an attachment means for attaching insulation mats (12, 12') each laid surroundingly around a longitudinal portion of a pipeline (10), jointing spaces are formed between individual mats (12, 12'). A longterm durable, tensioned, locked connection at each joint space is desired. Preferably, divided, bendable, semi-rigid attachment bands of metal, exhibiting tensile strength are used. These are placed individually in the area of each joint space and tightened around neighbouring end portions of adjacent insulation mats (12, 12') while the attachment band (18a, 18b) is centred laterally in that an internal bead engages guidingly into the joint space (16). One end portion (18b') of one attachment band half (18b) may be fastened to the adjacent end portion (18a') by means of screws (22), while the other end portions (18a' and 18b') are provided with holes (24') and plastically deformable lips (24) to be passed therethrough, respectively, the efficient length of the attachment band halves (18a and 18b) and the positioning of the lips (24) and of the holes being such that the threading of the lips (24) through the holes and their subsequent bending causes a tightening of the attachment band (18a, 18b). The lip material acts as a locking means for the tightening and retaining action of the attachment band (18a, 18b) to the insulation mats (12, 12').

Title: Fault protection for hitless and errorless switching of telecommunications signals
Inventor: CASTRO PETER RAYMOND
IPC: H04L69/40
Filed: 2000-05-11
Abstract: In a distributed switch architecture, each incoming signal is sliced into a plurality of sub-signals. A checksum function is applied to subsets of data in each sub-signal to generate and add a checkbit to the sub-signal for each subset of data. Two copies of the augmented sub-signal are routed in parallel through redundant portions of the distributed switch fabric. Only one of the resulting routed sub-signals is selected for use in generating the corresponding outgoing signal, which is generated by combining data from selected routed sub-signals corresponding to all of the original sub-signals. Checksum analysis is performed on the two routed sub-signals to determine if a fault has occurred. If a fault is detected in the routed sub-signal currently being selected for use in generating the outgoing signal, the selection is changed so that the other routed sub-signal is used. The checkbits are preferably added to the sub-signals in place of terminated overhead data in the transmission format of the incoming signal. By appropriate selection of the size of each subset of data (i.e., if the size is not too small). the number of checkbits added to the sub-signals will not increase the size of the data routed through the distributed switch fabric relative to the size of the data in the transmission format of the incoming signal. In addition, an appropriate selection of the size of each subset of data (i.e., if the size is not too big) ensures that the fault protection scheme of the present invention will satisfy requirements for errorless switching in which the total detection time from a single-point failure is kept within 60 nanosec.

Title: Device for injecting fluid into a wall of a blood vessel
Inventor: REISS ROBERT E
IPC: A61F2/958
Filed: 1998-01-30
Abstract: A method and device for injecting fluid into a treatment area are provided herein. One embodiment includes a balloon (16) catheter (14), the balloon having a plurality of injectors (20) extending outwardly. Fluid passageways (26) connect each injector with a fluid source (60). During use, the balloon is positioned in a vessel proximate the treatment area (54) and inflated to embed the injectors into the vessel wall. The fluid is thereby introduced into the fluid passageway (26), through the injectors (20), and into the treatment area (54). The second embodiment includes flexible tubes (64) having afore-mentioned injectors (20). The tubes (64) are mounted between a multi-lumen catheter (14) and a grommet. A wire (38) connected to the grommet is passed through a lumen (27) of the catheter (14). Once the device is positioned in a vessel, the wire is partially withdrawn. This forces the grommet to advance towards the catheter (14), which thereby forces the flexible tubes (64) to bow outwardly, embedding the injectors (10) into the vessel wall.
