Abstract: A safety chain circuit includes a plurality of protection devices connected between a first chain end and a second chain end, and an amplifier. The amplifier includes a first device switch and a second device switch connected between an input and an output, a first enabling switch connected between the second chain end and a second enabling switch, and a first control switch and a second control switch. The first enabling switch selectively enables the first control switch to control the first device switch. The second enabling switch selectively enables the second control switch to control the second device switch. The first control switch, when enabled, selectively controls the first device switch in response to receiving a first control signal. The second control switch, when enabled, selectively controls the second device switch in response to receiving a second control signal.

Abstract: An electronic safety actuation device for braking an elevator car includes a safety brake movable between a non-braking position and a braking position, a first electronic safety actuator operably coupled to the safety brake via a first link member, and a second electronic safety actuator operably coupled to the safety brake via a second link member. Operation of the first electronic safety actuator applies a force to the first link member to move the safety brake from the non-braking position to the braking position. Operation of the second electronic safety actuator applies a force to the second link member to move the safety brake from the non-braking position to the braking position.

Abstract: An elevator system includes a primary source of electrical power; a power unit having a power supply, the power supply producing DC power from the primary source of electrical power. A rescue storage device provides power to the elevator system when the primary source of electrical power is unavailable. The rescue storage device is coupled to an output of the power supply to provide additional DC power with the DC power when the primary source of electrical power is available and an increased power requirement is present.

Abstract: An elevator system includes a hoistway and an elevator car positioned in the hoistway and configured to travel along the hoistway. The elevator car includes an elevator car door. A door operator assembly is fixed in the hoistway at a landing floor and includes a sensor to sense presence of the elevator car at the landing floor; and a door operator mechanism to open both the elevator car door and a landing floor door when the sensor senses presence of the elevator car at the landing floor. A light source may be fixed at the hoistway and a light transmitter is positioned at the elevator car to gather light from the light source and output the light into an interior of the elevator car. A ventilation system may be fixed at the hoistway and is interactive with the elevator car to condition an interior of the elevator car.
