  • Patent number: 5067081
    Abstract: A portable electronic navigation apparatus and method utilizes universal latitude and longitude coordinates of geographic points and landmarks for determining current location or a specific destination and the distance and bearing thereof relative to landmark data input by the user. Latitude and longitude of population centers (e.g., cities, towns), major buildings, airports, and other landmarks in a geographical area are stored in a first memory. Latitudinal and longitudinal data for roadways in the area are stored in a second memory. A third permanent memory stores programs to; calculate the distance between two known points; look up and retrieve stored information; store and erase data upon the user's instruction; accept corrections to stored data; and to display the data on a screen in relation to its latitude and longitude along with name, mileage, and bearing or destination data corresponding to the related geographical feature or landmark.

  • Patent number: 5027549
    Abstract: An insect capturing device comprising a pair of elongate longitudinal members pivotally connected together at a point along their length to pivot relative to one another in a scissors fashion about the point of connection with handles at one end and a pair of foraminous cup-shaped members secured in opposed relation at the ends opposite the handles. The cup-shaped members are moved by the longitudinal members between an open position spaced a distance apart and a closed position where they are brought face to face to form an enclosure for capturing an insect therein. The open ends of the cup-shaped members are configured to facilitate secure engagement in the closed position and prevent accidental opening to allow the user to release the handle and still maintain the cup-shaped members in the closed position.
