Title: Anonymising data
Inventor: GIANNIOTIS ADAM
IPC: G06F21/62
Filed: 2012-07-20
Abstract: A method of anonyimising data comprises receiving data to be anonymised, and applying one or more transformations to the received data according to a transformation configuration resource, thus transforming an original portion into a transformed portion. The original portion is recoverable from the transformed portion (the transformation might be reversible) using stored information. The transformation might comprise encrypting the original portion of data, wherein the stored information comprises cryptographic material (decryption keys). The transformation might alternatively comprise hashing, redacting, filtering, replacing and masking the data. The transformed portion may be in the same format as the original portion. This method helps protect private, personal or sensitive information before being sent to third parties. Third parties may edit or use data in the transformed portion without being aware of private data in the original portion.

Title: Downhole tool having a friction stirred surface region
Inventor: DAVIS RICHARD
IPC: C21D1/06
Filed: 2011-03-31
Abstract: A method for hardening a portion of the outer surface of a downhole tool body includes friction stirring the vulnerable surface of the tool.Â  Such friction stirring generally includes rotation a friction stir weld tool in contact with the surface until a portion of the tool penetrates the tool.Â  The friction stir weld tool is the translated (while rotating) across a predetermined region of the surface thereby creating a friction stir zone.Â  The friction stir zone is generally considerably harder, and therefore more wear resistant, than the parent material that makes up the tool body.Â  The resulting downhole tool includes at least one surface with a hard friction stir zone.

Title: Photoacoustic Chemical Detector
Inventor: PAGE HIDEAKI
IPC: G01N21/17
Filed: 2013-02-28
Abstract: A photoacoustic chemical detector 100 for detecting one or more target chemicals in a sample gas or liquid comprises a light source 108 (e.g. Fabry-Perot laser) to irradiate a sample within a sensor cavity 104, which generates an acoustic signal that is detected by a microphone 116.

The light source is encoded by controlling the drive current, voltage and/or operating temperature in order to produce a multimode emission (each mode having a defined frequency and intensity). The encoded drive signal applied to the light source results in a varying trace in the photoacoustic signal that can be used to analyse and identify the chemicals in the sample in the photoacoustic cell. The photoacoustic sensor 102 comprises a housing with optical window 110, microphone 116 and cavity 104.
