A pallet capable of fixing display panels having various sizes substantially normal to the pallet, a method of fixing the display panels using the pallet, and a method of transferring the pallet are provided. When an interface prot is inserted into the host, other interface ports are off-line automatically. The output generated by the comparison circuitry may comprise an encoded digital output signal representative of the value of the internal resistor. The elongate body has a contracted configuration for insertion into the patient and an expanded configuration for providing access to the surgical location. Clients interact with the display using a wireless communications or computing device. The present invention processes a generated image by dividing the generated image into at least two regions or mask images, separately processing the at least two regions of the image, and viewing the resultant processed region images either alone or as a combined image.
