  • Patent number: 10391527
    Abstract: An ozone cleaning system includes a cabinet defining a cleaning space, and an ozone generator disposed in fluid communication with the cleaning space and configured to produce and introduce ozone therein for cleaning items with ozone. An ozone neutralization unit is attached to the cabinet and includes an inlet and outlet tube each disposed within the cabinet. The ozone neutralization unit includes a heater/blower assembly in fluid communication with each tube and operable for heating and recirculating the ozone within the cleaning space. A method of operating the ozone cleaning system includes receiving an input to commence an ozone cleaning cycle, and then producing and introducing ozone into the cleaning space. The method proceeds by determining if the ozone cleaning cycle is complete, and then initiating and executing an ozone neutralization cycle to accelerate the rate of ozone neutralization after the ozone cleaning cycle is complete.

  • Patent number: 9702166
    Abstract: An electronic lock driven by a keep solenoid has a non-direct mechanical connection between the solenoid plunger and the slidable deadbolt of the lock. The connection includes a pivoted lever connected to the plunger and a link between the lever and the deadbolt, these components being arranged in such a way that when the deadbolt is fully extended the pivot point of the lever and pivot points on both ends of the link, with the lever and with the deadbolt, are in alignment. The mechanical arrangement prevents retraction of the extended deadbolt by pushing inward on the deadbolt, which is a problem with a deadbolt driven directly by a solenoid plunger.

  • Patent number: 9689982
    Abstract: An object detection device for a vehicle monitors the surroundings at the rear of the vehicle. The object detection device has a radar sensor for generating a radar signal containing information about a distance between the vehicle and a vehicle user or another object in the surroundings. The radar sensor mounts on a vehicle component pointing toward the surroundings to the rear of the vehicle. Furthermore, the object detection device contains a control and evaluation unit for determining a movement pattern of the vehicle user on the basis of the radar signal, and to compare the movement pattern with a predefined reference pattern and to actuate a servomotor which has the purpose of actuating the tailgate between an open position and a closed position when the movement pattern corresponds to the reference pattern. Furthermore, a vehicle ideally has such an object detection device.
