Publication number: 20210045601Abstract: Apparatus and method for receiving and holding debris in a collection chamber of a vacuum cleaner. The collection chamber has an inlet opening through which debris-entrained air enters the collection chamber. When the vacuum cleaner is off, the cover prevents debris from leaving the collection chamber through the inlet opening. The wall of the collection chamber moves when negative pressure is applied to the collection chamber, and the wall movement moves the cover from the inlet opening, allowing the debris-entrained air to enter the collection chamber. In some embodiments, the moving part of the wall is an air filter.Type: ApplicationFiled: November 4, 2020Publication date: February 18, 2021Inventors: Michael James DOUGLAS, Richard MATHIAS

Publication number: 20210045595Abstract: Methods and apparatus for cleaning a surface with a cleaning device having a body with a handle, a connector, and one or more cleaning heads that are removably attached to the cleaning device. Each cleaning head include a lower surface arranged to contact a surface to be cleaned and a dirt collection chamber permanently attached to the cleaning head. The cleaning head may include a support structure to support the dirt collection chamber and a cleaning sheet. The cleaning head also may include a suction nozzle. At least a portion of the dirt collection chamber may be made of a filter material.Type: ApplicationFiled: November 4, 2020Publication date: February 18, 2021Inventors: Samuel Emrys JAMES, Michael James DOUGLAS, David Stephen CLARE, Chris PINCHES, Nicholas James SARDAR, Hugh James CROGGON, Damian LEE

Patent number: 10801921Abstract: Systems and methods for improving fuel economy in vehicles such as Class 8 trucks are provided. In some embodiments, signals indicating states of the powertrain are collected and used to generate fuel rate optimization values. Fuel rate optimization values may indicate a difference between optimum fuel flow rates and actual fuel flow rates during a vehicle drive cycle. Recorded fuel rate optimization values may be used to compare different vehicle configurations during testing, and may also be used to evaluate vehicle performance during real-world operation.Type: GrantFiled: September 16, 2019Date of Patent: October 13, 2020Assignee: PACCAR INCInventors: Christopher Michael James Douglas, Michael Douglas Gerty, Mark G.
