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.

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.

Each of a plurality of disparate facility components can be provided with a communications interface. That interface, in turn, can serve to facilitate communicating operational data between individual ones of such facility components and, for example, a central self-storage facility controller. This interface can comprise a wireless or a non-wireless interface as desired. These teachings will also accommodate the use of one or more wireless repeaters to support such an approach.

Upon detecting a secondary influence of interest one automatically controls one or more overlooks for one or more of the self-storage units as comprise a part of a self-storage facility. The secondary influence can comprise, for example, a weather condition (such as a sleeting weather condition) that is capable of causing the overlock to persist a given lock state (such as a presently-locked state). The automatic action can comprise, for example, automatically removing the overlock condition for some or all of the presently overlooked self-storage units regardless of the present contractual propriety of maintaining an overlooked state.

A system is disclosed including a transmitter and receiver for the communication of security codes which may be validated at the receiver to operate equipment. In one embodiment, the transmitter transmits a security code at two frequencies contemporaneously to the receiver which may receive both frequencies and resolve the security code therefrom. The receiver may lock onto one frequency to the exclusion of the other frequency when parts of a security code are detected. In another embodiment, the transmitter selectively transmits security codes at a default frequency which is selected because of a recorded count of prior apparent successful transmission.

A barrier movement operator moves a barrier between open and closed positions. The operator receives a first request to move the barrier. The actual force required to move the barrier is measured. An obstruction to barrier movement is determined by comparing the measured actual force to a first predetermined force threshold. Responsive to the detection of an obstruction, the direction of travel of the barrier is reversed. The operation of the barrier movement operator is modified, by permitting the use of a higher force threshold in future measurements. A second request to move the barrier is received. The actual force required to move the barrier is measured a second time. An obstruction to barrier movement is detected by comparing the measured actual force with the new, higher force threshold.

A central facility automatically receives status information regarding at least three different kinds of system elements and processes that status information to provide a corresponding status report. These teachings will readily accommodate a wide variety of system elements including, but not limited to, area lights, security cameras, overlooks, movable barrier status detectors, point-of-entry elements, sensors of various kinds, data communication paths, and so forth.

A movable barrier controller 41 has a force control 44 having a corresponding setting range. As operating conditions change, the barrier controller 41 can execute a learning mode 51. During this mode, the barrier controller 41 operates the barrier movement motor 42 and measures 53 at least one parameter that corresponds to operation of the motor 42. This measured parameter is used to determine 54 a control value which control value is then assigned 55 to a specific location within the setting range of the force control 44.
摘要:
A movable barrier operator having a motor controller (10) and motor (11) that control selective movement of a movable barrier (12) also has an obstacle detector (14) that utilizes an automatically determined excess force threshold value to permit reliable detection of an obstacle under a wide variety of operational circumstances, including changing physical circumstances, aging components, temperature variations, and motor runtime. In a preferred embodiment, a characteristic force value for the system is frequently updated as a function of actual measured force requirements (and further compensated, pursuant to various embodiments, with respect to other conditions such as temperature and motor runtime). This characteristic force value is then utilized to determine the excess force threshold value.
摘要:
A movable barrier operator transmits a message to a remote peripheral platform and, upon determining that the remote peripheral platform is presently able to carry out a given functionality, responsively permits a particular function to be carried out by the movable barrier operator. Conversely, upon determining that it cannot be ascertained whether the remote peripheral platform is presently able to carry out the given functionality, the movable barrier operator responsively prevents the movable barrier operator from carrying out the particular function. Also, upon detecting that a targeted remote platform does not acknowledge a previously re-transmitted message and further upon detecting that this same remote platform has also not acknowledged a subsequent wirelessly-transmitted second message, the system can switch to automatically retransmitting that second message a lesser number of times than would otherwise be required.
