Abstract: A personal illumination and safety device employs a flexible plastic rod to distribute the light of a light emitting diode (LED). A small container at one end of the flexible rod houses the LED, a battery and a switch which controls the illumination system. The flexible plastic rod allows the user to adapt the device to a variety of shapes and useful arrangements.

Abstract: A recreational or competitive flying disc includes an illumination system employing an array of flexible optical fibers to distribute the light of a single light emitting diode (LED) from the rotational center of the disc to its outside periphery. A small water-resistant compartment centered on the underside of the disc houses the LED, battery, and the illumination control. The leads of the LED also serve as the contacts of the battery. One end of each of the optical fibers is embedded in the LED, and the other end extends radially from the central housing on the underside surface of the disc to the rim of the disc. The flying disc is illuminated without altering the aerodynamic properties of the disc.

Abstract: A method and an apparatus for repelling ants and other insects positions design flow of DC current in design proximity to targeted areas (1), facilities, equipment and AC electrical devices occupied by or likely to be occupied by the ants and other insects. The apparatus includes a DC ant and insect repeller having an electromagnet conductor wire (2) with electromagnetic windings (3) charged with predetermined flow of DC electricity. Charge of DC electricity is predetermined for preventing heat in excess of 140° F. while causing electrical resistance within a range of 50-to-90 ohms in the electromagnetic windings. Preferably for portably versatile-use repellers, the electromagnetic windings are a spool 2-to-6 inches long between insulating washers (17 and 18). Coated conductor wire for the electromagnetic coil has a diameter within a range of 0.010-to-0.020 inches (26-to-32 gauge) with a plurality of 2,000-to-2,500 windings.

Abstract: The present invention is directed to a method of making a multilayered fabric comprising a first absorbable nonwoven fabric and one or more a second absorbable woven or knitted fabric.

Abstract: A digital video recording system (10) includes a video camera (12) directed at a scene of interest to continuously view the scene and generate video images (F) of the scene. An image processor (14) is configured to compare the video image (F) with a previously established reference image (Fr) of the scene to determine if changes have occurred. The image processor includes a memory (20) in which portions of video images (F) are stored, together with the time and date information as to when the image was acquired. A video playback capability (30) allows the memory to be accessed to retrieve the portions of the video images for image reconstruction. The playback system enables the memory to be accessed at any desired date and time location so an image of interest can be reconstructed without having to scan stored video images in a date/time sequence. Accessing the memory is done without interrupting the image processor's processing of currently acquired video images.
