Patent GB-2458991-A (GB)
Title: Mechanical linear actuator with zero backlash
Inventor: RHODES JOHN DAVID
IPC: F16H25/20
Filed: 2008-04-09
Abstract: A mechanical linear actuator, for a tuneable microwave resonator, comprises a drive arm 2 and an extension arm 3 each extending along a common drive axis 5. The extension arm 3 is at least partially received in a housing 4 which allows displacement of the extension arm 3 along the drive axis 5 but prevents rotation of the extension arm 3 about the drive axis 5. Drive arm 2 and extension arm 3 are engaged via threads 10, 11 such that rotation of the drive arm 2 about the drive axis 5 displaces the extension arm along the drive axis 5. The housing 4 comprises a housing body 6 and a plurality of resiliently deformable gripping fingers 7 extending from the housing 4 and gripping the extension arm 3 therebetween. The gripping fingers 7 deform and force the threads 10, 11 together eliminating backlash and thereby holding the extension arm 3 in an equilibrium orientation relative to the drive axis 5. The two threads 10, 11 are arranged such that when a ridge (14, fig 3) of one thread 11 is received in a groove (15) of the other thread 10 two sides (16, 17) of the ridge (14) abut two edges (18, 19) of a mouth of the groove (15). In another embodiment camming surfaces form the ridges and grooves.

Title: Using an ECB mode symmetric encrypt cipher algorithm to perform (in addition to encryption) decryption, authentication and pseudorandom number generation
Inventor: WHITAKER BEN JOHN DIXON
IPC: H04L9/06
Filed: 2008-05-07
Abstract: The proposed invention is a specific configuration of cryptographic ciphers and modes of operation that allow a full cryptographic suite comprising a random number generator, an asymmetric cipher, a symmetric cipher and a message authentication code generator, to be implemented in the smallest logic gate or programmatic footprint, thus enabling devices with limited resources (such as mobile telephones) to make use of cryptography to recent recommended standards for bi-directional secure communications with a predetermined server. The key to achieving this is to implement the asymmetric cipher and symmetric cipher in only the encrypt direction, and make use of specific modes of operation to enable all other functions (such as hashing or pseudorandom number generation) without relying on any additional ciphers or cryptographic algorithms. The original abstract stated that the invention "avoid(ed) having to implement the decrypt operations of any of the ciphers", but according to the description Cipher Feedback (CFB) mode decryption can be performed using the encrypt mode of the core symmetric cipher. At other points in the application the blockwise encoding used is said to be Electronic Code Book (ECB).

Title: Method of separating a multiphase mixture
Inventor: RAGHURAMAN BHAVANI
IPC: B01L99/00
Filed: 2005-09-07
Abstract: A fluid separation method comprises separating a multiphase mixture 106 with a porous membrane 108 in a micro-fluidic device wherein a pressure difference is maintained across the membrane below a capillary breakthrough pressure of a non-wetting component of the multiphase mixture; wherein the separating includes flowing the multiphase mixture across the membrane in a direction parallel to the membrane such that the flowing of a liquid of interest is from the multiphase mixture through the membrane at a flow rate at least one or two orders of magnitude lower than a flow rate of the multiphase mixture passing the membrane. The passing of the liquid through the membrane prevents fouling without backflushing. Fluid analysis is accomplished with microfluidic devices and may be reported in real-time or near real-time in a subterranean environment. In addition or alternative to oilfield applications, the principles of the present invention contemplate separation in a laboratory or other environment for biological sample separation and analytical chemistry applications. The present invention is capable of separating liquid-liquid mixtures or emulsions in a microfluidic device without fouling.

Title: Precoding selection for a user in a THP MIMO system
Inventor: CAO FENGMING
IPC: H04L1/06
Filed: 2009-01-09
Abstract: In a Multiple In Multiple Out (MIMO) system of receivers each having nr antennas employing nonlinear Tomlinson-Harashima precoding (THP) in K independent data streams forming an nrxK channel matrixH, interference between data streams is first reduced by pre-subtracting known interference elements (B-I) from a channel symbol vector in a feedback loop containing a modulus operation (MOD) and transformed into vectorXby a feed-forward matrixFH. Channel matrixHis decomposed with LQ decomposition to generate a feedback matrixBand a diagonal matrixG-1which eliminates interference, and a receiver combination matrixRcalculated. To maximise capacity, the transmitter must select a precoding scheme based on channel knowledge, for which exhaustive searching becomes intractable for large user numbers.Rfor a given user number is therefore determined by maximising the square of the norm of a diagonal element of a triangular matrix generated by the Gram-Schmidt process during LQ decomposition of matrixRHfor each MIMO channel (Step 13 in fig. 3). This allows performance to be flexibly adjusted according to the number of active users.
