A shield that is attachable to a touch sensitive screen is disclosed. The ion enhancement system of the present invention is used to direct a heated gas toward ions produced by a matrix based ion source and detected by a detector. The electrical resistance heating element can be on either the inner surface or the outer surface of the transparent front panel, preferably the inner surface. The end region is disposed adjacent to the outboard end and has a fastening element zone and an intermediate zone. The reaching aid apparatus includes an elongated member with an actuation handle assembly at one end and a grabbing elements assembly at the opposite end for grabbing, lifting and holding objects. The shorts find particular application in battlefield theatres where military personnel are exposed to bomb threats.
