Abstract: The present invention pertains to the art of sensing articles typically moving on a conveyor. An apparatus is disclosed, for the purpose of securely attaching a sensing device to a sub-structure such as a sidepan metal sheet that contains a hole through which the sensing/detection device passes its sensing beam. A primary novelty of the apparatus is that it enables secure mounting of various ‘through-hole’ devices without the need for attaching any additional bracketry and without creating obstructions to package movement. It is unique in that it utilizes the “through-hole” which is necessary to allow passage of the sensing beam through the side guards of the conveyor, with the below-surface attachment being made possible by means of a tapered, or ‘sloping’ surface that is created when the hole is made.

Abstract: The disclosure relates to a flexible material that can be adhered to small devices such as: calculators, cellular phones, Personal Data Assistants, email devices, TV or stereo remotes, digital cameras, laser pointers, electronic toys or the like, and performs as a retainer to the user's hand when one inserts a finger or fingers between the flexible material and the device. The retainer allows the device to be retained on the hand, and also allows the digits of that hand to function and operate the device. The retainer precludes the user from using compressive muscular pressure to hold the device, which can contribute to cramping and pain. The invention also enables the use of these small devices by users with diminished or compromised functionality of the hand or fingers, such as arthritis, amputation or similar.
