Abstract: A monitoring and control device for use in a remote monitoring and control system includes a display unit provided with a screen for displaying operation buttons mated with the loads, an operation input unit operable by a user, the operation input unit including a touch switch panel superimposed on the screen of the display unit and a control unit for performing display control of the display unit and load control in response to the operation of the operation input unit. The control unit includes a display control unit for causing the display unit to display one operation page selected from a plurality of operation pages containing different combinations of operation buttons and a page changeover unit for changing over the operation page displayed on the display unit in response to a user's operation.

Abstract: A compact GPS receiver includes a GPS antenna composed of a patch and a ground plane to receive high frequency satellite signals, an analog circuit which processes the high frequency satellite signals into a digital signal, a digital circuit which processes the digital signal to compute positional coordinates of the GPS antenna, and an interface connector which outputs the positional coordinates to an external device. A substrate is provided to support the GPS antenna, the analog circuit, the digital circuit, and the interface connector. An EMI (electromagnetic interference) shield is provided to shield at least the digital circuit to block a noise developing at the digital circuit from interfering with the GPS antenna. The GPS antenna is mounted on the EMI shield to share the ground plane with the EMI shield, while keeping the patch insulated electrically from the EMI shield.
