A method and system for inspecting and monitoring an elevator installation includes sending an autonomous flying object having at least one sensor to the elevator installation, and granting access to a hoistway of the elevator installation to the autonomous flying object. The autonomous flying object is positioned within the hoistway, and data collected by the associated sensor is sent to a remote elevator service center. The autonomous flying object and the associated sensor can be used to monitor and inspect the elevator installation on a temporary basis, for example for a specific number of hours, days or weeks. Once the autonomous flying object has gained access to the hoistway, the elevator installation can resume normal operation thereby keeping downtime to a minimum. After completing its tasks at one elevator installation, the autonomous flying object can be directed by the remote elevator service center to monitor and inspect another elevator installation.

An artifact caused by secondary reflection is reduced. An imaging device according to an embodiment includes: a diffuser (110) that converts incident light into scattered light whose diameter is expanded in accordance with a propagation distance and outputs the scattered light; and a light receiver (132) that converts light diffused by the diffuser into an electric signal.

An equipment inspection system receives data captured by a sensor of an autonomous vehicle (AV). The captured data describes a current state of equipment for servicing the AV. The equipment inspection system compares the captured data to a model describing an expected state of the equipment. The equipment inspection system determines, based on the comparison, that the equipment differs from the expected state. The equipment inspection system may transmit data describing the current state of the equipment to an equipment manager. The equipment manager may schedule maintenance for the equipment based on the current state of the equipment.

A fire detection device includes a vented detector housing, with an opening defined in a mounting base. A substance exhaust channel in air flow communication with the opening extends upward from the mounting base. A pressure release turbine includes an impeller operatively disposed in the channel. A rotation sensor senses rotation of the impeller and generates an alert upon detection of a heat level indicated by rotation of the turbine rotor at a predetermined speed. A high pressure and/or heat louver disposed over the opening opens in response to a predetermined heat level. An actuator detects opening of the louver and generates an alert.
