    摘要: Micro capacitive switches and methods of manufacturing micro capacitive switches at variable nominal capacitance value using micro-structures on the contact plates of the same dimension. In a preferred embodiment, a separately manufactured contact plate can be mounted to a movable magnet in order to be actuated to “on” and “off” state of the capacitive switch. Depending on the contact plate's surface condition, variable contact capacitance at “on” state can be precisely specified by geometrical properties of the micro-structures on the surface, such as the density, size and depth.

    摘要: The present invention relates to a method for measuring a location of a radio frequency identification (RFID) reader by using beacons, and an RFID system for measuring a location of a moving RFID reader in an RFID system comprising: a plurality of beacon devices for emitting beacons; an RFID tag for transmitting pre-stored information by using radio frequency identification; and an RFID reader for calculating a current location using a plurality of at least three beacons wherein the RFID reader receives the plurality of beacons from the plurality of beacon devices while moving, and receiving the information from the RFID tag by using the radio frequency identification. According to the present invention, it is possible to increase the accuracy of the location measurement of a moving RFID reader in an RFID system because the location of the RFID reader is measured in consideration of propagation environments.
