    Abstract: According to an aspect, a method includes monitoring a plurality of vibration data by a vibration monitoring beacon and determining that the vibration monitoring beacon has been installed at a service location based on detecting an installation characteristic signature in the vibration data. The vibration monitoring beacon can transition into a learning mode based on determining that the vibration monitoring beacon has been installed at the service location. The method can also include monitoring for a learning mode termination event and transitioning the vibration monitoring beacon from the learning mode to a normal operation mode based on detecting the learning mode termination event.

    Abstract: Methods and systems for determining elevator car locations are provided. Aspects includes a sensor affixed to a moving component of an elevator system, wherein the sensor is operated by a controller and wherein the controller is configured to determine that the elevator car is in motion based at least in part on the sensor. A direction of the elevator car is determined while the elevator car is in motion based at least in part on the sensor. Sensor data associated with the elevator car is collected while the elevator car is in motion, wherein the sensor data includes a travel time while the elevator car is in motion. Elevator car travel data is accessed from a travel time profile associated with the elevator car and the travel time is compared to the elevator car travel data to determine a location of the elevator car in a hoistway.

    Abstract: A frictional damper for an elevator system includes one or more friction pads configured to move between a first position, and a second position defined by engagement of the one or more friction pads to the guide rail. An actuation unit urges the one or more friction pads into and out of engagement with the guide rail. The actuation unit includes a hydraulic actuator operably connected to the one or more friction pads to urge movement of the one or more friction pads into and out of engagement with the guide rail via hydraulic fluid pressure. The hydraulic actuator includes a hydraulic cylinder containing a volume of hydraulic fluid and a hydraulic piston located in the hydraulic cylinder and operably connected to the one or more friction pads. An electromagnetic actuator selectably urges hydraulic fluid to apply a force to the hydraulic piston, urging the movement of the friction pads.

    Abstract: A method of monitoring a conveyance apparatus within a conveyance system is provided. The method including: obtaining a starting location position probability distribution of the conveyance apparatus within the conveyance system; detecting motion of the conveyance apparatus away from the probable starting location for a period of time; determining a distance traveled by the conveyance apparatus during the period of time; determining a direction of motion of the conveyance apparatus during the period of time; and determining a probability of the conveyance apparatus being at each of a plurality of possible destination locations at a conclusion of the period of time in response to the starting location position probability distribution and at least one of the distance traveled, the direction of motion, and the period of time.

    Abstract: Enclosed space air conditioning systems having air conditioning module(s) with an enclosure defining a cavity, a thermoelectric element arranged to condition air within the cavity, an air direction mechanism to direct air from the cavity into an enclosed space, and an electronics package for controlling the air direction mechanism and the thermoelectric element, the electronics package including a detection element to detect when an occupant in the enclosed space is in proximity of the at least one air conditioning module. The electronics package is configured to activate the air direction mechanism and/or the thermoelectric element when the occupant is detected, deactivate the activated air direction mechanism and/or thermoelectric element when the occupant is no longer in proximity, and/or activate the air direction mechanism and/or the thermoelectric element to maintain an enclosed space preset condition.
