Abstract: A movable barrier operator controls access to a secured area which houses vehicles. The movable barrier operator is operable to move a movable barrier from an open to a closed position. A sensor controls the operation of a service-providing device through the controller of a movable barrier operator or by direct communication to a controller for the service-providing device. The sensing device senses whether a vehicle is present in the secured area. The sensor is operatively connected to the moveable barrier operator and is used to control the operation of at least one service-providing device without necessarily effecting movement of a barrier by the movable barrier operator. Operation of the service-providing device is effected upon sensing whether a vehicle is present in the secured area to effect an operation of the service-providing device.

Abstract: One or more repeaters enable the conveyance of both asynchronous and synchronous transmissions. This can comprise receiving, via a first carrier, a transmission from a message source that is asynchronous with respect to a time slot partitioning of the communication protocol and then, when the asynchronous transmission is received during an asynchronous source transmission portion, buffering a corresponding message until a next available synchronous time slot opportunity during the asynchronous source transmission portion and then transmitting the message via the first carrier to at least attempt to forward the message.

Abstract: A barrier operator system is provided including a controller, a motor, a barrier, a power source, and a remote transmitter. The controller scans for a reduced range of radio frequencies while operating in a standby mode to conserve energy. In response to receiving a signal from the remote transmitter, the barrier operator will exit the standby mode and scan for a broader range of frequencies. In response to receiving a command signal from the remote transmitter, the controller will operate the barrier. The controller also scans for signals from an accessory device after exiting the standby mode. The accessory device may also operate in multiple modes with respect to scanning for transmissions and sending signals to the controller.

Abstract: A pool of identifiers are individually used by corresponding particular ones of a repeaters. A communications protocol as used by the repeaters provides time slots to be used by these repeaters when making their transmissions. Each of the time slots is associated with individual corresponding ones of the identifiers, though the time slots are allocated unequally amongst the identifiers such that at least one of the identifiers has more time slots allocated to that identifier, over a given beacon cycle, than others of the identifiers.

Abstract: A first value of an operational center frequency of a signal to transmit is determined according to received user input. The operational center frequency is centered within a first band of frequencies and the first band of frequencies has a first bandwidth. A single loop antenna is tuned to match the first value of the center frequency and the single loop antenna is arranged and configured to operate across a second band of frequencies having a second bandwidth. The first bandwidth is less than the second bandwidth. The signal is transmitted from the single loop antenna according to the first value of the operational center frequency to provide a transmitted signal.
