  • Patent number: 6007207
    Abstract: A rear view mirror combination is particularly suitable for monitoring obstructions in typical blind spot locations as well as directly to the rear. An accessory for a rear view mirror includes a base for mounting to a structure that supports a main mirror nominally oriented in a main reflection plane; a first auxiliary mirror mounted to the base and extending generally vertically relative to the structure and vertically offset from the main rear view mirror, the first auxiliary mirror is angled outwardly between approximately 25 degrees and approximately 50 degrees from the main reflection plane. The base can have a vertically projecting face portion for fastening to a forwardly facing surface of the structure, or a generally downwardly facing face portion for fastening to an upwardly facing surface of the structure.

  • Patent number: 5443875
    Abstract: Disclosed is a protective patch for smoothly covering labels in existing garments. The patch includes a flexible member formed of cotton flannel, and an adhesive material on the flexible member. The adhesive material forms a first adhesive that extends within a ring-shaped region proximate an edge margin of the flexible member, the first adhesive being releasable from the garment for exposing the label. A marginal portion of the flexible member is folded against a facing portion of the flexible member for forming a double thickness of the flexible member with the edge margin being spaced inwardly from an outer perimeter of the patch. A second adhesive secures the marginal portion to the facing portion, the marginal portion having a corner width at locations of minimum radius of the outer perimeter, the corner width being less than half of the minimum radius for limiting projections of the perimeter margin away from the facing flexible material.
