A patch and a treatment method for the treatment of human discomforts include transdermal administration of components from soap in the area of discomfort. The method involves placing a ball of conducting thermoplastic resin, such as a gold or silver epoxy, between the terminal pads of the transducer and using the ball to shunt the pads to read-head shields and the slider substrate and thence to ground. The guide structure can be configured to transmit light from the first display panel at a first position, through the guide structure, to a second position spaced apart from the first display panel.
