Abstract: The REX cryptosystem presented herein is a variant of the NTRU cryptosystem. In the REX cryptosystem, a primary ring RXOR and two secondary rings RXOR,q and RXOR,p are used to reduce the number of operations required to compute the keys, to perform the encryption process, and to perform the decryption process. The REX cryptosystem may also be implemented using Walsh-Hadamard transformations to significantly increase speed.

Abstract: A method for manufacturing valve metal anodes of electrolytic capacitors by deoxidizing the anodes using Mg vapor in a deoxidizing furnace, removing the anodes from deoxidizing furnace, placing them in sintering furnace, sintering at temperature lower than the temperature conventionally used for sintering in vacuum, and leaching of Mg oxide off the anode surface. The process limits free oxygen and improves morphology of valve metal anodes, which results in improved performance of electrolytic capacitors with these anodes. The process does not require any special equipment or maintenance operations and, thereby, is highly productive due to performing deoxidizing and sintering separately in traditional deoxidizing and sintering furnaces.

Abstract: Embodiments of the present invention provide a new system and methods for monitoring blood glucose concentration.

Abstract: Embodiments of the invention are devices for assisting users in the management of blood glucose concentration levels in patients. Devices of the invention provide users with detailed information related to the pharmacodynamic behavior of insulin in a patient. By displaying and accepting information concerning time-dependent rates and amounts of pharmacodynamic insulin unit equivalents, the devices of the invention empower the user to make effective decisions regarding insulin dosing.

Abstract: An electro-optic waveguide polarisation modulator (20) comprising a waveguide core (4) having first and second faces defining a waveguide core plane, a plurality of primary electrodes (22, 24) arranged at a first side of the waveguide core plane and out of said plane, and at least one secondary electrode (26) arranged at a second side of the waveguide core plane and out of said plane, wherein the electrodes (22, 24, 26) are adapted in use to provide an electric field having field components (13, 15) in two substantially perpendicular directions within the waveguide core (4) so as modulate the refractive index thereof such that electromagnetic radiation propagating through the core (4) is converted from a first polarisation state to a second polarisation state.

Abstract: A method and apparatus for depth imaging by triangulation in which a pattern is projected on to an object scene and the scene, and the pattern, imaged, the projection and the imaging being spatially offset, in which the pattern has a characteristic dimension x and depth changes in the object scene cause deformations in the image of the pattern having a maximum dimension ?x, characterised in that ?x<x.

Abstract: A block cipher is provided that secures data by encrypting it based on the memory address where it is to be stored. When encrypting data for storage in the memory address, the memory address is encrypted in a first plurality of block cipher rounds. Data round keys are generated using information from the first plurality of block cipher rounds. Data to be stored is combined with the encrypted memory address and encrypted in a second plurality of block cipher rounds using the data round keys. The encrypted data is then stored in the memory location. When decrypting data, the memory address is again encrypted as before while the encrypted stored data is decrypted in a second plurality of the block cipher rounds using the data round keys to obtain a partially decrypted data. The partially decrypted data is combined with the encrypted memory address to obtain fully decrypted data.

Abstract: Disclosed is a method for evaluating resistance to cryptanalysis of a cipher structure having a diffusion element including a linear transformation placed between differently-sized confusion elements at an input and an output of the diffusion element. A generalized minimum number of non-zero symbols at the diffusion element's input and output is determined. The diffusion element's input is divided into subset inputs, each having a size corresponding to the size of each confusion element at the diffusion element input. For each subset input, a subset number of non-zero symbols at the subset input and the diffusion element output is determined. Each subset number is summed to generate a summed subset number. The summed subset number is subtracted from the generalized minimum number to generate a worst-case number. An upper bound of a maximum differential characteristic probability is calculated and used to evaluate the cipher structure.

Abstract: A method of depositing items of value, the method comprising 1) receiving a tamper evident and coded container holding the items of value, the code relating to the content of the container; 2) verifying that the package has been received in an acceptable manner, and, if it has, 3) either incrementing an account with the value of the items of value in the container by reference to the code and without opening the container, or, if the account has previously been incremented, leaving the account unchanged.

Abstract: A schema-based service for Internet access to per-user services data, wherein access to data is based on each user's identity. The service includes a schema that defines rules and a structure for each user's data, and also includes methods that provide access to the data in a defined way. The services schema thus corresponds to a logical document containing the data for each user. The user manipulates (e.g., reads or writes) data in the logical document by data access requests through defined methods. In one implementation, the services schemas are arranged as XML documents, and the services provide methods that control access to the data based on the requesting user's identification, defined role and scope for that role. In this way, data can be accessed by its owner, and shared to an extent determined by the owner.

Abstract: Methods and apparatus are presented for encrypting and authenticating data, wherein some data is encrypted and some data is not encrypted, but all of the data is authenticated. Masking modules (410) are used in a partial-block encryption mode to indicate which bits of a data block are to be encrypted.

Abstract: A solar collector arrangement includes a number of assemblies (1), which are immersed or partially immersed in a pond of water (2). Each assembly (1) includes a parabolic reflector (3) and an absorber (6). Barriers (10) are located on or near the surface of the water (2) and operate to reduce waves which may otherwise disturb the direct passage of sunlight in windy conditions. The complete immersion of the assembly (1) in the liquid serves to simultaneously protect and cool the apparatus, while allowing ease of sun 10 tracking movements by buoyancy induced rotation. Partially immersed versions have higher efficiency and protect against severe weather by inverting into the water.

Abstract: A method for a server to initiate resynchronization with an access terminal, when synchronization has been lost, that cannot be exploited by attackers is provided. The server may provide the access terminal with a secret key that is only known to the access terminal and the server. The access terminal may store the secret key in a secure storage device to prevent the secret key from being hacked. If the server determines that synchronization has been lost, the server may send a resynchronization message to the access terminal with the secret key attached. The access terminal retrieves the stored secret key from the secure memory device and compares it to the secret key attached to the resynchronization message. If there is a match, the access terminal may initiate a secure communication link with the server to reestablish synchronization.
