Abstract: A computer implemented data product release method or system. The data product release is derived from a sensitive dataset using a privacy protection system such as a differentially private system. The privacy protection parameters, such as noise addition magnitude, are configurable as part of the data product release method or system to alter the balance between maintaining privacy of the sensitive dataset and making the data product release useful.

Abstract: An adhesive application system for an automated block laying machine, the adhesive application system including: (a) an adhesive supply; and, (b) an adhesive applicator including: (i) a container for storing an adhesive reservoir received from the adhesive supply via an adhesive supply line; (ii) a lid mounted to the container so as to substantially cover the adhesive reservoir; and, (iii) an adhesive roller rotatably coupled to the container so that upon rotation adhesive from the reservoir is entrained up and around at least a portion of the adhesive roller, wherein, in use, adhesive is transferred from the adhesive roller onto a bottom surface of a block as the block is moved across the roller.

Abstract: A system allows the identification and protection of sensitive data in a multiple ways, which can be combined for different workflows, data situations or use cases. The system scans datasets to identify sensitive data or identifying datasets, and to enable the anonymisation of sensitive or identifying datasets by processing that data to produce a safe copy. Furthermore, the system prevents access to a raw dataset. The system enables privacy preserving aggregate queries and computations. The system uses differentially private algorithms to reduce or prevent the risk of identification or disclosure of sensitive information. The system scales to big data and is implemented in a way that supports parallel execution on a distributed compute cluster.

Abstract: A block transfer apparatus for transferring a block between an upstream and downstream clamps of a block delivery system. The apparatus includes: a frame pivotally mounted to a support; a clamping assembly mounted to the frame and linearly extendable relative thereto, and including a pair of gripper jaws for clamping opposing sides of the block. The apparatus receives a block in the gripper jaws in an approximate position; rotates to a drop position and releases the block allowing it to self-datum onto first and second orthogonal datum surfaces. The apparatus re-clamps the block after the drop by applying a clamping force to opposing sides of the block to register the block against a third datum surface to thereby datum the position of the block with respect to the clamping assembly; and presents the block clamped in the datumed position for transfer to the downstream clamp.

Abstract: Methods of storing data records produced from monitoring interactions between external agents and a system are described. The method defines specific interactions that occur between the external agents and the system as events of interest. A chain of interactions occurring during respective interaction sessions between a respective external agent and the system are monitored and events of interest occurring in the chain are determined. Data records from the monitored chain are produced, the respective data record including data identifying determined events of interest and data associated therewith. A profile identity, representative of the external agent, is assigned to each data record produced during an interaction session. Data records of individual events of interest are stored in a way ordered according to the type of event of interest and data records of events of interest occurring during an interaction session are stored in a way ordered according to assigned profile identity.

Abstract: A toner composition including a binder, a colorant, and a surface additive package including a surface treated silica, a surface treated titania, and magnesium stearate.

Abstract: A toner having at least one binder, at least one colorant and external additives. The external additives include at least one of silica and titania, and at least two metal stearates. A developer may be produced including the toner having at least two metal stearates and a carrier. An electrophotographic machine includes the toner with two metal stearates.

Abstract: A toner composition for use in a xerographic or electrostatographic imaging process. The toner composition includes a toner particle and an optional primary external surface additive and a friable external surface additive. The friable external surface additive may also be a material that is capable of functioning as a primary external surface additive. The friable external surface additive is generally larger than the primary surface additive and capable of having portions of the friable particle broken or abraded off during the imaging process. The particles that are abraded off the friable additive can replace the primary external additive particles that become embedded into toner particles during the development process. The friable additives contribute to reducing toner aging and provide a toner with satisfactory flow and triboelectric properties.

Abstract: UV sensing apparatus comprises a substantially light-proof housing (1), an aperture (1a) formed in the housing, a filter (2) positioned within the housing at the internal mouth of the aperture, a fluorescent member (3) positioned within the housing on that side of the filter remote from that adjacent to the aperture, and a light sensor (4) positioned within the housing to receive light emitted by the fluorescent member. The filter (2) is such that it substantially removes visible light, the fluorescent member (3) is such as to fluoresce when subjected to UV radiation, and the light sensor (4) is positioned so that substantially none of any electromagnetic radiation entering the housing (1) via the aperture (1a) impinges upon the light sensor.
