  • Patent number: 11872593
    Abstract: Devices and methods for improved separation of small particles from other stock. The device includes a sifting tray assembly and means for vibrating the screen of the sifting tray assembly for separating components and a cryogenic fluid source and injection system for freezing the small parts to the point where they are solid enough to pass through the screen without adhering to the screen. The method entails use of the system to separate small particles in sifting trays while spraying the stock with a cryogen such as liquid nitrogen.
    Type: Grant

  • Patent number: 7983761
    Abstract: An electro-acupuncture device for controlling nausea. The device includes a wristwatch like housing, circuitry for generating electro-acupuncture stimulus disposed within the housing, and a strap for securing the housing to the wrist. The device also includes a pair of D-shaped electrodes disposed on the bottom outer surface of the housing. A gasket made of an electrically non-conductive material is applied to the bottom outer surface of the housing. The gasket has apertures which are sized and shaped to receive the D-shaped electrodes. When the device is strapped to a patient's wrist, the electrodes contact the wrist and provide electric stimulation to the wrist.

  • Patent number: 7171266
    Abstract: An electro-acupuncture device for controlling nausea. The device includes a base unit which is includes a wrist-watch like housing, circuitry for generating electro-acupuncture stimulus disposed within the housing, and a strap for securing the housing to the wrist. The base unit has a standardized construction. The device also includes a releasably attachable electrode assembly. The electrode assembly attaches to the base unit of the device. The electrode assembly includes a pair of electrodes and connectors for connecting the electrodes to the circuitry of the base unit. The output of the device is dependent upon the circuitry of the electrode assembly. Thus various electrode assemblies can be made. The circuitry of the base unit modifies the output of the device depending upon which electrode assembly is attached to the base unit.

  • Patent number: 7171276
    Abstract: A hydrogel and scrim assembly adapted for use with an electro-acupuncture device to enhance electrical conduction between the device and the skin and to provide an impedance matching layer between the device and the skin. The assembly includes a scrim with conductive hydrogel masses disposed on the surface of the scrim. The hydrogel masses are sized and dimensioned so that when the pad is adapted to the device, the hydrogel masses do not bridge the electrodes to cause a short between the electrodes.
