Abstract: A circuit for an RFID tag has at least two RF ports for driving points of the antenna that may correspond to different RF polarizations. The RF ports may be driven by a common modulating signal, or by separate modulating signals. Further, the ports may be coupled and uncoupled together, responsive to a control signal. The control signal may be the same as one or both of the modulating signals.

Abstract: In a method for commissioning radio-based emergency alarm systems, having a master station (7) with a transmit and receive arrangement and peripheral elements (1 to 6), each also having a transmit and receive arrangement, in a cell, the peripheral elements are fitted and supplied with energy, whereupon they transmit search telegrams and then switch to receive mode. Peripheral elements (1 . . . 6), which receive a search telegram from a search peripheral element (1 . . . 6) while in receive mode, transmit a response telegram to the searching peripheral element (1 . . . 6). The availability tables of the peripheral elements (1 . . . 6) in mutual contact with each other are then supplemented and a structure is thereby automatically created among the already fitted peripheral elements (1 . . . 6).

Abstract: When either a front-side sensor or a rear-side sensor of a subject vehicle detects an obstacle entering a certain distance range of multiple distance ranges within a detection zone close to the subject vehicle, a micro-computer causes a warning unit to warn with a buzzer in a primary warning pattern that is prepared for each distance range. In contrast, when both detect obstacles, the warning unit is caused to warn in the following patterns. In a first case that at least one of two sensors detects an obstacle entering a shortest distance range, the warning unit warns in a different warning pattern differentiated from the primary warning pattern. In a second case except the first case, the warning unit warns in the primary warning pattern corresponding to the distance range that is entered by the obstacle that is closer to the vehicle, of the obstacles detected by the two sensors.

In one aspect, the on-vehicle alarm generation method for detecting a passerby and generating an alarm to a driver includes the steps of including a dangerous driving point in map data and detecting the vehicle position; monitoring whether the vehicle approaches the dangerous driving point; transmitting a searching signal when the vehicle approaches the dangerous driving point; monitoring whether, in response to the searching signal, a responsive signal is received from a mobile device carried by the passerby; and generating an alarm to the driver upon receiving the responsive signal.

Abstract: A remotely controlled electronic display sign which operates with a plasma display and which provides for humidity and heat control and the like allowing the sign to be used in various environments. The sign is essentially self-contained and includes those components necessary for enabling a display of desired material from a remote control source or one located at the sign. A controller in or associated with the sign is accessible either electrically, or through satellite transmission or other wireless transmission from the remote source which allows the display of the sign to be changed at will. Thus, an operator at a remote source may, with the aid of a pre-prepared graphic design, transmit that design to the controller at or associated with the sign for display of that graphic information and potentially with sound.
