Abstract
Abstract An electrically conductive strap having a distal end adapted to be secured to an object and having a proximate end adapted to be coupled to electrical ground. The strap has an elongate strip of electrically conductive material being flexible in at least one dimension. The material has an object contacting portion at the distal end, a lead portion between the distal end of the proximate end and a ground contacting portion at the proximate end. An adhesive securing mechanism is provided at the object contacting portion of the elongate strip of electrically conductive material to secure the material in electrical contact with the object. A ground contacting mechanism is provided at the ground contacting portion of the material to be able to couple the electrically conductive strap to electrical ground.
