    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: 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.

    Abstract: A transfer station (40) for a ropeless elevator system hoistway (11) is provided. The transfer station (40) includes a first lane (13, 15, 17), a second lane (13, 15, 17), and a parking area (42) located proximate one of the first lane (13, 15, 17) and the second lane (13, 15, 17). The transfer station (40) also includes a plurality of carriages (46) moveable within the first lane (13, 15, 17), the second lane (13, 15, 17), and the parking area (42), the plurality of carriages (46) configured to support and move an elevator car (14). The transfer station (40) further includes a cassette (44) configured to support and move the plurality of carriages (46). The transfer station (40) yet further includes a guiding member (48) engaged with the cassette (44), wherein the position of each of the plurality of carriages (46) relative to the first lane (13, 15, 17), the second lane (13, 15, 17) and the parking area (42) is modified by horizontal or vertical movement of the cassette (44).
