Abstract: A display system for wall or table use which incorporates multiple two-sided display panels that allow either face of the panels to be viewed and to lie parallel with adjacent panels when rotated 180 degrees from one side of the device to the other is disclosed. Suitable for home, office, or commercial use, the construction of the device presents a decorative appearance and provides for display of multiple images or small objects, or a combination of small objects and images. The construction of the device allows the device to be wall mounted or attached to a base and used as table display. The device can be economically configured for portrait or landscape orientation of popular sized displays. Using the same components, customized versions can be economically fabricated. A variety of materials can be used to construct the display system.

Abstract: This is an entirely new type of tactile display based upon cuneiform writing concepts which is an alternative to Braille. This invention uses electromechanical components to display a tactile coding of letters, numbers and symbols using rotating linear components and pointer variations of these. These pointer parts rotate on the surface of the device. A user places fingers or skin on the surface and by feeling the direction in which the components are pointing determines the coded symbol.

Abstract: A trimmer blade assembly comprising a blade within a housing is provided. The housing includes a wall for propelling cut vegetation away from the blade assembly. The blade assembly may also include a ridge on the housing for further propulsion of cut vegetation away from the trimmer blade. The present blade cuts vegetation more efficiently since cut vegetation will generally be propelled away from the blade by the perpendicular wall and ridge.

Abstract: A one-piece, transparent flexible ear coupler for use with hearing evaluation is disclosed. It includes an annular side wall and a bottom wall forming an acoustic chamber. A flexible adhesive-backed flange is disposed on the periphery of the ear coupler. The flange attaches to the subject's head, firmly holding the ear coupler in place over the ear. The annular side wall has a port for the placement of a transducer assembly, and also has ribs to help lock the transducer assembly in place. The transducer assembly can be placed in an up or down position, and can be switched between positions while the coupler is attached to the subject's head. The ear coupler advantageously conforms to the subject's head, thereby minimizing the likelihood that the ear coupler will become detached during testing. The coupler can be inexpensively manufactured, since its one-piece design allows the use of relatively low-cost processes such as injection molding and thermoforming.

Abstract: A flying insect trap containing a light, a fan, and a heater is disclosed. A light controller controls the operation of the light, so that the light can turn off or blink when it is time to change the adhesive paper that traps the insects or the bait that attracts the insects.
