    Systems and methods for monitoring bone fusion
    (2019) Munro, Deborah
    Systems and methods utilize a strain sensor to monitor the status of bone fusion. The systems include a sensor system that measures an initial strain in a medical device implanted in or disposed on a bony structure to obtain an initial strain value, and measures a subsequent strain in the medical device to obtain a subsequent strain value. The systems also include a reader or a processor that calculates a magnitude of the difference between the subsequent strain value and the initial strain value or a magnitude of the difference between a current strain value and a previous strain value. If the magnitude of the difference is greater than the predeter mined difference value, the sensor system measures multiple strain values, and the processor calculates an average slope based on the multiple measured strain values, and, if the average slope is less than the predetermined slope, generates a notification that bone fusion in a bony structure has occurred.

    Strain Monitoring System and Apparatus. Patent no US 8,066,650 B2
    (2011) Munro, Deborah; Lee, Eunice; Ramahi, Amjad
    A system for monitoring strain as an indicator of biological conditions, such as spinal fusion, glucose levels, spinal loading, and heart rate. The system includes an inter-digitated capacitor sensor, and RF transmitter, and an associated antenna, all of which are microminiature or microscopic in size and can be implanted in a biological host such as a human or animal. An inductively coupled power supply is also employed to avoid the need for implantation of chemical batteries. Power is provided to the sensor and transmitter, and data is transmitted from the sensor, when an external receiving device, such as a handheld RF ID type receiver, is placed proximate the location of the implanted sensor, transmitter and inductively coupled power supply. The implanted sensor, transmitter and inductively coupled power supply can be left in place permanently or removed when desired.

    IC Chip to PC Board Connector System
    (1994) Ikenaka K; Munro, Deborah
    In accordance with one embodiment of the present invention, an apparatus of moderate cost is provided which can readily releasably connect an integrated circuit to a circuit board. The apparatus includes a socket that can be readily mounted on the circuit board, the socket forming a largely rectangular cavity which closely receives the integrated circuit. The socket has a lower portion forming vertical through slots, each slot extending parallel to one of the sides of the rectangular socket. An elongated vertically-compressible interface device lies in each of the slots, each interface device having a row of compressible conductors with upper ends pressing against conductive pads on the underside of the integrated circuit, and each compressible conduc tor having a lower end pressing against a conductive trace on the circuit board. A cover or the like mounts on the socket and presses the integrated circuit down wardly into the socket, to compress the interface de vices to interconnect the integrated circuit to the circuit board.

    The Lathe: Engineers Take Note of Dimensions When Designing Components
    (2019) Munro, Deborah
    Lathes perform a unique role in manufacturing. Unlike all other machine tools which operate in a rectilinear space, lathes use rotation about an axis as their primary operation and create cylindrical objects with a central axis of symmetry. Lathes are used to make shafts, screws, pulleys, pins, and wheels, among countless other examples. With a CNC lathe, it is possible to machine nonsymmetrical parts, such as cams on a crank shaft. Like other machine tools, lathes can be either manually operated or CNC controlled. This article refers to high-powered metal lathes, although wood lathes can be used for some soft metals, like brass. The safety hazards, however, are different.

    (2019) Millen P; Buck K; Palmer H; Altaner, Clemens
    EXECUTIVE SUMMARY The NZDFI has developed this regional strategy to provide a rationale and overview of its planned activities over the next three years and beyond. The strategy identifies six key focus areas where skills, knowledge, resources and investment are needed to continue to build the capability required to establish a new durable hardwood industry. This strategy highlights what has been achieved through enduring partnerships and a collaborative approach that attracts forest growers, farmers, Māori, regional councils, Government and industry organisations to provide ongoing support and invest in making a future hardwood industry possible.
