Abstract:
A method for tracking memory changes includes defining a change-track area of memory including at least one memory address range for which changes will be tracked. The method also includes allocating a protected log region of memory for storing a change- track log and selecting an operational mode for change tracking from among a plurality of modes, the selected operational mode having criteria for tracking memory changes. The method includes detecting memory transactions using a memory logging module and generating a transaction record for each memory transaction that occurs in the change- track are of memory and which meets the criteria. The transaction records can be stored in the change-track log.
Abstract:
An ion source for a mass spectrometer is disclosed comprising a lens 308 and mirror 303 arrangement which focuses a laser beam 302 onto the upper surface of a target substrate 305. The lens 308 has an effective focal length ≤ 300 mm. The laser beam 302 is directed onto the target substrate 305 at an angle θ with respect to the perpendicular to the target substrate 305, wherein θ ≤ 3°. One or more ion guides 311 receive ions released from the target substrate and onwardly transmit the ions along an ion path which substantially bypasses the lens 308 and mirror 303.
Abstract:
A distributed tempero-spatial query service uses a plurality of service agents each having an assigned area of responsibility. The service agents are organized into a spatial hierarchy based upon each service agent's area of responsibility. The spatial hierarchy is distributed and hosted on each of the service agents. The spatial hierarchy enables matching of requests from subscribing agents with publishing agents based upon spatial attributes. The spatial hierarchy is dynamically maintained in a distributed manner on each of the service agents. The service agents can be arranged into a tree- based spatial hierarchy having a limited depth.
Abstract:
A process for the selective removal of a component from a liquid phase and subsequently returning the component to a liquid phase is disclosed. A novel compound of formula (I) [SUP]-[[L]-[G]]a (I) in which L is a linking group, G is an aryl group having a leaving group LG selected from Cl, Br, I, sulfonate such as triflate, a diazo group, a nitrile, an ester and an alkoxy group and substituent Q is selected from H, NR2, OR, C02R, F, Cl, N02 CN and SUP is a support having a plurality of groups -[L]-[G] bound to the support is contacted with the liquid phase to bind the component to the compound I thereby forming a captured component which is separated from and may be returned to the liquid phase. The compound I is especially useful in binding homogeneous catalysts to remove it from a reaction medium and selectively returning the catalyst to the reaction medium at a later stage. The compound is particularly useful for cross-coupling reactions, for example in Suzuki reactions.
Abstract:
A method of mass spectrometry is disclosed comprising directing first photons from a laser onto ions located within a 2D or linear ion guide or ion trap. The frequency of the first photons is scanned and first photons and/or second photons emitted by the ions are detected. The ions are then mass analysed using a Time of Flight mass analyser.
Abstract:
Systems and methods for closed-loop feedback control of controllable devices using motion capture systems are disclosed. In one embodiment, a system includes a motion capture system configured to measure one or more motion characteristics of one or more controllable devices as the one or more controllable devices are operating within a control volume. A processor receives the measured motion characteristics from the motion capture system and determines a control signal based on the measured motion characteristics. A position control system receives the control signal and continuously adjusts at least one motion characteristic of the one or more controllable devices in order to maintain or achieve a desired motion state. The controllable device may be equipped with passive retro-reflective markers. The motion capture system, the processor, and the position control system comprise a complete closed-loop feedback control system.
Abstract:
An imaging device is disclosed. The imaging device has a housing, a detector positioned within the housing and has a field of view encompassing one or more target area within the housing to be imaged, a wide-angle lens operatively coupled to the detector, and a support positioned at the target area and configured to receive one or more test component. The wide- angle lens is operatively coupled to the detector such that the detector receives image data of the target area through the wide-angle lens.
Abstract:
A pulsed ion source is disclosed wherein the ion source is energised one or more times to generate a first group of ions and a second group of ions. The first and second groups of ions are simultaneously transmitted through an ion guide whilst keeping the first and second groups of ions isolated from each other.
Abstract:
An adaptor for a spanner, comprising an elongate body having a spanner engagement portion and a socket engagement portion, and a through bore to allow insertion of a constraining tool in use through the body is provided. The adaptor allows a conventional spanner, such as a ratchet ring spanner, to be used with a number of sockets. This advantageously reduces the number of tools required for a particular job. Additionally, the adaptor allows a suitable constraining tool to pass through its body and engage with a suitably adapted shaft of a fastener, e.g. an ASNA bolt. The constraining tool can be used to constrain rotation of a fastener whilst a nut is driven thereon by the socket. This is particularly desirable where access to the head of a fastener is not possible or is substantially limited, or where the shape of the fastener head prevents adequate engagement of a suitable tool therewith or where the fastener has no head. The adapter may be provided in a set, with a constraining tool and/or with a spanner or socket set.
Abstract:
Embodiments of solar cell arrays are described which involve a design of a solar cell array and a method for the processing of individual cells into an array comprised of multiple cells interconnected in series and/or parallel to achieve any desired electrical output and to provide for a non-uniform appearance of colour.
