A method for providing elevator services includes: generating a dispatch command for stopping an elevator to a departure floor of a target device with self-propelled capability in response to an elevator reservation message from a computer system, wherein the elevator reservation message includes an identification of the target device and an identification of the departure floor; instructing the computer system to send a confirmation message to the target device, the confirmation message includes a password associated with the target device; after the elevator stops at the departure floor of the device and before starting the elevator, determining whether a state of the car satisfies set conditions, wherein the set conditions at least include: an identity authentication of the device in the car based on the password has passed; and if the set conditions are satisfied, the elevator is started; otherwise, the elevator is prohibited from starting.

A safety monitoring device of an elevator system having a shaft extending over at least two floors has a safety circuit with door contact switches being closed or opened accordingly when a respective shaft door is closed or opened. The door switches form an electrical series circuit that is electrically broken to block the elevator car from moving when any of the door switches is opened. The monitoring apparatus has at least one bypass switch that actuates a first door switch for a first shaft door on a first floor such that, when the elevator car reaches the first floor, the bypass switch bypasses the first door switch to switch the safety circuit independently of the first door switch. A monitoring means of the monitoring apparatus monitors the switching state of the safety circuit and/or of a second door switch for a second shaft door on a second floor.

Elevator maintenance space projection systems and elevator systems including a projector located within an elevator shaft and arranged to project a display space within the elevator shaft such that the display space includes one or more projected images identifying at least one of a safety volume, a refuge space, and a maintenance location.

A method of controlling building systems including detecting a status parameter of a door of a building; displaying the status parameter of the door on a device; detecting a status parameter of a door lock, the door lock being operbly connected to the door; and displaying the status parameter of the door and the status parameter of the door lock on a device.

A notification device and a notification method to announce a current operation mode of an elevator, especially a maintenance or inspection mode, is provided for the elevator that executes the notification method. The elevator includes a control assembly allocated outside of a shaft of the elevator, wherein the notification device is electrically connected or communicates with the control assembly. The notification device includes a display that displays information depending on the status of a lock of the control assembly, wherein the display is off or displays a predetermined first information when the lock is locked, and the display is on and displays a predetermined second information when the lock is unlocked.

According to an aspect, there is provided an elevator car parking brake comprising a brake carrier having a first plate and a second plate, the plates being spaced from each other and positioned to enable a guide rail to travel within the space between the plates, a caliper movably connected to the brake carrier, brake pads, and an actuator configured to move the brake pads against a guide rail in a braking operation. The elevator car parking brake further comprises at least one first compression spring arranged between the first plate of the brake carrier and a brake pad directly associated with the actuator; and at least one second compression spring arranged between the second plate of the brake carrier and the caliper, the first and second compression springs being configured to keep the brake pads substantially centered with respect to the brake carrier.

Provided are embodiment for a method and a system for filtering unintended requests. The embodiments can include receiving an input to disable an elevator lock for an elevator car, and determining whether to unlock the elevator lock. The embodiments can also include unlocking the elevator lock based at least in part on the determination and permitting or prohibiting motion of the elevator car responsive to the determination.
