Abstract:
Foldable ladders and related methods for use within a pit of an elevator system include a first upright, a second upright, and a plurality of rungs pivotally mounted to each of the first upright and the second upright. A locking mechanism has a first segment pivotally attached to the first upright and a second segment pivotally attached to the second upright, and the two segments are pivotally connected. A locking device is located on an upright and operably connected to a segment. The locking device includes a first catch and a second catch, a pin moveable to engage with the first catch in a first position and moveable to engage in a second position. A biasing mechanism applies a force to the pin to engage the pin with a catch. An operating device is operable to apply opposing force against the biasing mechanism to disengage the pin from the catch.
Abstract:
An acoustic elevator communication system (1) comprises a speaker (4) on an output line (6) and a microphone (8) on an input line (10), the speaker (4) and the microphone (8) being installed inside an elevator car (2); a sound generator (24) connected with the output line (6); and an adjustment unit (25). The adjustment unit (25) is configured for (A1) driving the sound generator (24) for delivering a first speaker signal to the speaker (4), the first speaker signal in particular being a white noise signal causing the speaker (4) to produce white noise sound; (B1) receiving the sound generated by the speaker (4) with the microphone (8) generating a first microphone signal; (C1) determining acoustic resonances from the first microphone signal; (D1) adjusting the speaker signal such as to eliminate the acoustic resonances in the first microphone signal.
Abstract:
The present disclosure relates generally to a selectively operable magnetic braking system having a safety brake adapted to arrest movement when moved from a non-braking state into a braking state, a magnetic brake configured to move between an engaging position and a non-engaging position, the magnetic brake, when in the engaging position, moving the safety brake from the non-braking state into the braking state, and an electromagnetic component configured to hold the magnetic brake with a hold power in the non-engaging position.
Abstract:
A self-diagnostic circuit includes an electrical conductor configured to multiplex, a first switch interposing the electrical conductor, and a first module crossing the first switch. The first module includes a first receptor antenna associated with the conductor on one side of the first switch, a first emitter antenna associated with the conductor on an opposite side of the first switch, and a first interfacing microprocessor. The first interfacing microprocessor is configured to receive no signal from the first receptor antenna when the first switch is open thus generating a first open signal and a first address signal indicative of the first module and outputting the first open signal and the first address signal to the conductor via the first emitter antenna. The first interfacing microprocessor is further configured to receive a first induced frequency signal from the first receptor antenna when the first switch is closed thus generating a first closed signal and the first address signal indicative of the first module and outputting the first closed signal and the first address signal to the conductor via the first emitter antenna.
Abstract:
In one aspect, a method for initiating elevator service by entering an elevator call on a call input device (14) having a plurality of graphical objects (22) displayed on a graphical user interface (20) is provided. The method includes the steps of selecting a first landing graphical object (24) from the plurality of graphical objects, and selecting a second landing graphical object (24) from the plurality of graphical objects. The method also includes selecting a third landing graphical object (24) from the plurality of graphical objects. The method also includes creating an anticipated trip graphical object (26), the anticipated trip graphical object indicating a trip from the third landing to the first landing. The method also includes selecting the anticipated trip graphical object (26) to initiate a hall call and floor call from the third landing to the first landing.
