Abstract: A computer system includes physical memory devices of different types that store randomly-accessible data in a main memory of the computer system. In one approach, data is stored in memory at one or more logical addresses allocated to an application by an operating system. The data is physically stored in a first memory device of a first memory type (e.g., NVRAM). The operating system determines an access pattern for the stored data. In response to determining the access pattern, the data is moved from the first memory device to a second memory device of a different memory type (e.g., DRAM).

Abstract: Systems, methods and apparatuses of distributed computing based on memory as a service are described. For example, a set of networked computing devices can each be configured to execute an application that accesses memory using a virtual memory address region. Each respective device can map the virtual memory address region to the local memory for a first period of time during which the application is being executed in the respective device, map the virtual memory address region to a local memory of a remote device in the group for a second period of time after starting the application in the respective device and before terminating the application in the respective device, and request the remote device to process data in the virtual memory address region during at least the second period of time.

Abstract: The present disclosure provides a linear actuator apparatus, magnetic sensor system and method of use for detecting a position of a component driven by a rotatable mechanism in a linear direction. A magnetic sensing device comprising both a multi-turn (MT) sensor and a single turn (ST) sensor is provided within the same semiconductor package and placed in the vicinity of the rotatable mechanism. A magnet is mounted on the rotatable mechanism, such that, as the mechanism rotates, a rotating magnetic field is generated. The MT sensor measures the number of turns of the rotating magnetic field, which is translated to the number of turns of the rotatable mechanism. The ST sensor measures the angle of the rotating magnetic field, which is translated to an angular position of the rotatable mechanism.

Abstract: The present disclosure provides a device for initializing a multi-turn sensor that initializes the sensor almost instantaneously, thereby consuming very little energy. The initialisation device is provided in the form of a conductor that is placed a small distance above or below the sensor spiral, the conductor being configured so that it crosses at least two opposing corners of the spiral. A current is then applied to the conductor to generate a magnetic field in the corner sections of the spiral to nucleate domain walls. Once the domain walls have been nucleated, the external magnetic field will drive the pairs of domain walls away from each other towards the adjacent corners, changing the magnetic alignment of the tracks as they pass through. As such, the spiral can be initialised very quickly by applying a current to the conductor in the correct direction.

Abstract: The present invention relates to a container for transport and storage of excavator attachments. In particular, but not exclusively, the present invention relates to a container for securing excavator attachments on a trailer. A container for retaining an excavator attachment on a trailer comprises a lower portion including a base, a pair of opposing end walls, and a front wall; a lid connected to the lower portion and arranged to pivot between a first position, in which the container may receive an excavator attachment, and a second position, in which the excavator attachment is retained by the container; and a coupling configured to secure the container to a trailer such that the end walls of the lower portion are adjacent side walls of the trailer and the front wall of the lower portion is adjacent a front wall of the trailer, wherein a depth of the lid, in a direction perpendicular to the base of the container, is greater than a depth of the lower portion.

Abstract: The present disclosure provides magnetic sensor system that includes a magnetic sensing device comprising a magnetic multi-turn sensor, and an initialization device for setting the magnetic multi-turn sensor in a known state ready for use. The initialization device is in the form of a substrate, such as a printed circuit board, comprising one or more wires. A strong electrical pulse is applied to the one or more wires, which thereby generate a magnetic field that is strong enough to cause the magnetoresistive elements of the magnetic multi-turn sensor to be filled with domain walls, thereby magnetising each element into an initialized state.

Abstract: A securing system for securing an item of plant machinery to a trailer comprises a retainer disposed in a forward region of the trailer, the retainer comprising a recess for receiving a part of a dozer blade of said plant machinery, and the retainer being configured such that movement of a dozer blade engaged with the recess is restricted in forwards, rearwards and upwards directions relative to a floor of the trailer.

Abstract: A method and apparatus are provided for whitening teeth using a fluid delivery toothbrush to deliver a bleaching liquid to the teeth during brushing. The fluid delivery toothbrush may be manual or powered, delivering fresh relatively high strength bleaching liquid to the tooth surfaces, preferably on a daily basis, for one to three minutes.
