The wall station also provides a periodic lighting element so as to easily direct the user to push the hinge cover to initiate up/down movement of the barrier.

Abstract: A method for interrogating objects to identified over a communication medium utilizes objects that include a counter. The objects provide predetermined responses indicative of object identification numbers. Interrogation signals operate to interrogate a signal digit from the objects. Incomplete identification numbers are recorded and retrieved whenever two or more predetermined responses are received from the objects. A signal is sent to the objects to cause the objects to selectively add a number to their respective counter. The number is determined by each object and is dependent upon one or more previous responses of the object to interrogation signals. A signal is sent to the objects to cause the objects to selectively subtract a number from their respective counter. The number is determined by each object and is dependent upon one or more previous responses of the object top the interrogation signals. Complete identification numbers are recorded as they determined.

Abstract: A method of reading a plurality of transponders 14.1 to 14.n forming part of an electronic radio frequency identification system 10 comprises the steps of prompting the transponders at 38 to transmit preambles 30 only of respective response digital sequences to a reader 12. The reader then locks onto the preamble 30 transmitted by one of the transponders and immediately causes a mute signal 38 to be broadcast to mute all of the transponders not yet transmitting. The reader then transmits during a first time window 42 a first command 40 to cause the one transponder to transmit a remainder of the sequence. Having received and read the remainder, the reader transmits a second command 44 during a second time window 46 to cause the one transponder to switch to a sleep mode wherein the one transponder no longer transmits any part of the sequence, and to unmute the muted transponders.

Abstract: A memory rewriting system for a vehicle controller is provided. The system comprises a vehicle controller and an external rewriting device. A vehicle controller comprises a rewritable memory storing first security data. The first security data is used to determine whether rewriting to the rewritable memory is permitted. The rewriting device transfers new security data to the vehicle controller. The vehicle controller deletes the first security data and writes the new security data into the rewritable memory. Rewriting the new security data is performed by a program stored in a non-rewritable memory. Thus, the security data that is used to determine whether rewriting to the rewitable memory is permitted is rewritten with the new security data. Therefore, if the existing security data stored in the vehicle controller is invalidated, the security feature of the vehicle can be recovered. The vehicle may includes an anti-theft system.
