  • Patent number: 5673703
    Abstract: An apparatus for automated testing of vibrotactile responses of a patient is disclosed. The embodiment of the invention comprises a component to apply indentations and vibrations to the patient's skin to test the patient's response to vibrotactile stimuli. In the preferred embodiment of the invention, a general purpose computer functions to control the operation of the system and to record and store the patient's responses. Indentations and vibrations are produced by off-axis rotational movement of a stimulation probe. A frequency modulated signal generated by the computer is used to control the motor which drives the stimulation probe. The embodiment of the present invention is able to reliably repeat each test so that the tests are reproducible and are carried out in an objective manner.

  • Patent number: 5118608
    Abstract: An assay technique for qualitative and quantitative detection of a chemical, biochemical or biological detection of a chemical, biochemical or biological species in sample. The technique comprises: (a) coating at least a predetermined part of a pre-formed surface on a substrate with a thin film of a material capable of binding the species to be assayed, the pre-formed surface being optically active with respect to radiation at least over a predetermined band of wavelengths; (b) contacting the coated surface with sample; and (c) observing the optical properties of said pre-formed surface in order to determine a qualitative and quantitative change in optical properties as a result of the binding of the species onto said thin film of material. The optical properties as a result of the pre-formed surface may be observed before and after step (b) in order to determine any change in optical properties, or they may be monitored during step (b). The pre-formed surface is preferably a grating.

  • Patent number: 4532197
    Abstract: A method of forming an image on an electrophotographic film material is described. This involves a contact printing technique and comprises the following steps:(a) placing an image-bearing master in contact with the film;(b) exposing the film to light through the image-bearing master, the exposure being substantially greater than the minimum necessary to render conductive the photo-conductive layer of the electrophotographic film;(c) applying a substantially uniform charge to the surface of the film in the dark immediately after exposure;(d) leaving the film in the dark for a short time so as to allow the charge to migrate selectively; and(e) then developing the image.

  • Patent number: 4522482
    Abstract: An apparatus for recording information in the form of a two dimensional array of miniature images on a recording material such as electrophotographic, photographic or photochromic material. Means are included for forming those images (by such of the processes of sensitizing, charging, exposing, developing or fixing as are appropriate to the particular material used) from originals or copies of legible size. A facility is provided to form one or more miniature images occupying only part of a storage member on one occasion, and to record a further such image or images on later occasions. Guide means and propulsion means in two dimensions are included for adjusting the relative positions of the storage member and the image forming or image viewing device so that any image space may be presented to the image forming device and any image may be presented to an image viewing device.

  • Patent number: 4215480
    Abstract: A hand held digital read-out measuring instrument in which interference fringes are generated by the transmission of radiations through gratings which move relative to one another according to a distance being measured and the fringes are counted to detect changes in the fringe pattern and generate a pulse output related to the distance, means being provided to control the rate of movement and to exert a substantially constant force on the movable elements.

  • Patent number: 3935840
    Abstract: An engine unit operable independently or joined in multiples of two or more units for smoothing out the torque flow at slow speeds, each unit including a fuel-suction-compression assembly and a power generating assembly employing the same main shaft and separate valve shafts gear driven therefrom at a two-to-one ratio. Each assembly has a plate-like block bored out to provide a central cylinder chamber and two planetary cylindrical valve chambers. Fixed on the main shaft and rotating in said central chambers are two like rotors having cylindrical hubs and two arcuate segmental pistons extending diametrically therefrom to make smooth sealing rotational engagement with the walls of said central chambers. Fixed on said valve shafts are arcuate segmental valves making smooth sealing rotational engagement with said valve chambers and said rotor hubs.
