  • Patent number: 11686228
    Abstract: Systems and methods are provided for remotely monitoring liquid lubricant levels for pump equipment. A system includes a reservoir to store lubricant and a lubrication gland to expose a shaft seal of the pump equipment to the lubricant. A feed line and a return line circulate the lubricant between the reservoir and the lubrication gland. A level sensor is configured to measure a fluid level in the reservoir. The level sensor uses a communication interface to transmit fluid level data a monitoring device mounted to the pump equipment. The monitoring device is configured to compare the fluid level data against stored alert thresholds and send, to a provider network, an alert signal when the fluid level data is below an alert threshold. If the fluid level data is not below an alert threshold, the monitoring device stores the fluid level data for periodic reporting.

  • Patent number: 11679957
    Abstract: A method for operating an elevator having a car, a drive engine, shaft doors, signal receptors, an engine controller and a door controller. Each of the shaft doors is reciprocally opened and closed by an associated active door drive and has one of the signal receptors thereat. The method includes: receiving a requesting signal at one of the signal receptors; responding to the requesting signal by instructing the engine controller to control the drive engine to displace the car to a first position with the car roof adjacent to the shaft door at the floor from which the requesting signal originated when that floor is not the lowermost floor, and when the floor is the lowermost floor to a second position above the lowermost floor; instructing the door controller to control the door drive to actively open the door; and switching the engine controller to an inspection mode.
