  • Patent number: 9683957
    Abstract: A field effect transistor comprising a source including a plurality of electrode projections with spaces in between. A drain includes a plurality of electrode projections each located in one of the spaces between the electrode projections of the source thereby forming a drain-source electrode connection area of alternating drain and source projections. A gate is spaced apart from the drain-source electrode area thereby forming a channel between the gate and the drain-source electrode connection area wherein the gate runs parallel to the channel. A plurality of nano-structures is located in the drain-source electrode area thereby to form an electrical connection between the electrode projections of the drain and source in the drain-source electrode connection area. The invention extends to a gas detector including a plurality of field effect transistors as described above located on a substrate.

  • Publication number: 20170133678
    Abstract: A process for producing a layered lithium-manganese-nickel-cobalt oxide material, includes producing a raw layered lithium-manganese-nickel-cobalt oxide (‘LMNC’) material. Optionally, a dopant capable of enhancing the performance of the layered LMNC material when used as a cathode material in an electrochemical cell, is introduced during the production of the raw LMNC material. Before any annealing of the raw LMNC material is effected, it is subjected to microwave treatment. The resultant treated material is annealed to obtain the layered LMNC material.

  • Patent number: 9588488
    Abstract: Laser apparatus includes an output coupler, a gain medium for generating laser light, a rear optical element, and an input coupler. The input coupler is arranged to direct a pump beam to the gain medium and to define an optical path between the output coupler and the rear optical element. The rear optical element is a spatial light modulator arranged to act as an intra-cavity digital holographic mirror which can be digitally addressed. The spatial light modulator displays selectively a gray-scale image of a hologram thereby to phase-modulate laser light in the cavity, thus making it possible to generate an output laser beam having a desired characteristic. The apparatus includes a computer arranged to generate at least one hologram corresponding to a desired output beam characteristic, and a driver circuit responsive to an output from the computer to generate a corresponding gray-scale image of the hologram on the spatial light modulator.

  • Patent number: 9434710
    Abstract: The invention provides a process for hydrolytically converting aloeresin A to aloesin by the following reaction: The amount of aloesin available for extraction from sap of aloe plants is thereby increased and the extraction and purification of the aloesin is also made easier and less costly. As aloesin is more commercially valuable than aloeresin A, the process also increases the commercial value of the sap or aloe bitters from the aloe plant. The process optionally also includes the step of separating the aloesin from the p-coumaric acid. Typical hydrolysis steps that are used in the process are acid hydrolysis, base hydrolysis and enzymatic hydrolysis. In the case of acid hydrolysis, the acid is any suitable organic or inorganic acid, such as hydrochloric acid, sulfuric acid, nitric acid or phosphoric acid. In the case of enzymatic hydrolysis, the hydrolytic enzyme is typically an esterase, a lipase or a protease.

  • Patent number: 9434468
    Abstract: The invention provides a wing control system aimed at countering the aeroelastic effect of twisting of a length of wing of an aircraft due to dynamic air pressure acting on an aileron of the wing. The wing control system includes a shaft extending along the length of wing and actuation means responsive to aileron control inputs to induce a variable torque T in the shaft. Outboard of the length of wing, the system operatively transfers T partially to the aileron to pivot the aileron and partially to the wing at an outboard end of the length of wing to counter twisting of the length of wing due to dynamic air pressure on the aileron. Inboard of the length of wing, the system operatively transfers T to the aircraft, e.g. to its fuselage, thereby effectively balancing the sum of the moments transferred respectively to the aileron and the wing.

  • Patent number: 9330463
    Abstract: A system and method for calibrating a camera includes an energy source and a camera to be calibrated, with at least one of the energy source and the camera being mounted on a mechanical actuator so that it is movable relative to the other. A processor is connected to the energy source, the mechanical actuator and the camera and is programmed to control the mechanical actuator to move at least one of the energy source and the camera relative to the other through a plurality of discrete points on a calibration target pattern. The processor further, at each of the discrete points, controls the camera to take a digital image and perform a lens distortion characterization on each image. A focal length of the camera is determined including any lens connected to the camera and an extrinsic camera position for each image is then determined.
