A radio receiver portion of a transceiver includes a differential amplifier that is used to provide a fast response. The ice bank includes an ice accommodation chamber storing ice pieces made by an ice maker, and an ice pressing unit circulating the ice pieces by pressing the ice pieces for preventing sticking of the ice pieces in the ice accommodation chamber. The protection device while in the deployed position covers the windshield from an A pillar on a driver side of the vehicle to an A pillar of a passenger side of the vehicle and from an upper edge of the windshield to a position near a lower edge of the windshield. A pillar layer is deposited over the semiconductor structure; thereby filling the pillar openings with the pillar layer. Other imaging systems and a method are also disclosed.
