Title: Target-tracking radar and method for responding to fluctuations in target SNR
Inventor: TURNER DAMON C
IPC: G01S13/44
Filed: 2012-01-30
Abstract: Embodiments of a target-tracking radar and methods for responding to fluctuations in target SNR are generally described herein. In some embodiments, the target-tracking radar may be configured to determine whether a target can be considered a point target based on the SNR of received signals and off-boresight error estimates. Measurement-variance estimates generated from the SNR are provided to a target-state estimator when the target is determined to be a point target. When the target is determined not to be a point target, the measurement-variance estimates generated from SNR are not used by the target-state estimator. This may allow targets to be engaged at increased range.

Title: Thin client running in browser which accesses data (eg. device hardware fingerprint) via a software web server running locally on the computer
Inventor: JOHANNSEN ERIC ALAN
IPC: G06F21/53
Filed: 2011-05-09
Abstract: Processes running in web browsers 214 are typically sandboxed and given restricted access to device resources. A thin client 216 may need to authenticate itself to a remote server and this may involve submitting a digital fingerprint of the devices hardware. The thin clients security permissions do not allow access to the required information, therefore it makes a network call to a thick client 218 using a URL specifying a particular port on the computer. The thick client includes a web server 220 and logic for generating the fingerprint 222. In response to the thin client request the fingerprint is generated and then despatched via the web server to the thin client, which may then authenticate itself to the remote server.

Title: Parallel apparatus for high-speed, highly compressed LZ77 tokenization and huffman encoding for deflate compression
Inventor: MILNE ANDREW
IPC: H03M7/30
Filed: 2014-03-17
Abstract: Parallel compression, i.e. deflate compression performing Lempel-Ziv (LZ77) tokenization, is performed on an input data stream by processing circuitry 400. The processing circuitry 400 includes hashing circuitry 413, match engines 417, pipeline circuitry 418 and a match selector 420. The hashing circuitry 413 identifies multiple locations in one or more history buffers 416 for searching for a target data in the input data stream. The match engines 417 perform multiple searches in parallel for the target data in the one or more history buffers 416. The pipeline circuitry 418 performs pipelined searches for multiple sequential target data in the input data stream in consecutive clock cycles. Then the match selector 420 selects a result from the multiple searches and pipelined searches to compress the input data stream, i.e. using Huffman code lookup tables (LUTs) 436.

Title: Password-based generation and management of secret cryptographic keys
Inventor: CAMENISCH JAN LEONHARD
IPC: H04L9/08
Filed: 2014-08-26
Abstract: For password-based generation of a secret cryptographic key, a secret user value is provided at a user computer and a secret server value is provided at a server together with a check value (VC) based on the secret user value (S) and a user password (P). In response to input of a password (P) at the user computer, the user computer encodes the secret user value and the input password to produce a first value (V1) corresponding to the check value, and communicates this to the server via a network. In response, the server compares the first value and the check value to check whether the input password equals the user password. If so, the server encodes the first value and the secret server value (SK) to produce a second value (V2) and communicates this to the user computer. In response, the user computer generates the secret cryptographic key (K) by encoding the second value, the input password and the secret user value.

IPC: E02D31/08
Filed: 2014-10-20
Abstract: A building 7 is located over ground 8 which may release radon gas. An impermeable barrier or membrane 1 is positioned below the buildings floor slab. One or more mats 11 containing zeolite lie under the membrane. The mat(s) may have two layers, a gas and water impermeable layer and a gas permeable non woven layer (Fig 1, 15 and 17 respectively). The mat(s) may be shaped to allow projections, and corresponding pockets to be created (Fig 1, 16, 14) in a lattice like structure. The Zeolite (Fig 1, 18) may be located between said projections. Sump voids 2 are located below the mats and the void(s) are connected to pipes 4 to passively ventilate the void to atmosphere via outlets 3. The Zeolite acts to adsorb and entrain the Radon gas. Ambient air movement creates pressure differentials in the pipe to aid in venting the voids and pipes, thereby preventing Radon gas from entering the building.
