Title: Controller and method for operating starter motor
Inventor: STEPHEN STACEY
IPC: F02N11/08
Filed: 2018-12-21
Abstract: A controller 202 for a starter motor 208 and an engine 200 operable to receive a first input indicative of an engine shutdown being required, a second input indicative of a change-of-mind event having occurred after initiation of engine shutdown and a third input indicative of the engine position. On receiving the first input the controller 202 monitors the third input and determines an expected engine rotation direction after a predetermined delay. If positive rotation is expected and the second input is received then the controller 202 is configured to control the output means to cause the starter motor 208 of the engine 200 to be actuated upon receipt of the second input. If negative rotation is expected and the second input is received, then the controller 202 delays controlling the output means to cause the starter motor 208 of the engine 200 to be actuated until a determination is made that the expected rotation direction is positive. The invention aims to reduce the time required to determine whether or not the starter motor can be actuated.

Title: Flat roof drainage method
Inventor: ZHONG WANG
IPC: E04D13/064
Filed: 2021-03-08
Abstract: A flat roof water drainage method comprising: step S1, providing, in a water accumulation region of a roof, at least one recess communicating with a water drainage port; step S2, providing, in the recess, a drainage member for draining accumulated water; and step S3, adjusting a water drainage slope of the drainage member. If this method is applied to a new roof system, then a slope making layer of the new roof system can be eliminated, and smooth water drainage can be achieved by means of providing a drainage member and adjusting a water drainage slope of the drainage member. In addition, eliminating the slope making layer greatly reduces construction costs of a roofing project. If this method is applied to an existing roof system, then the issue in which water drainage of a roof region having accumulated water is not smooth can be resolved, maintenance difficulty and maintenance costs of the roof system can be greatly reduced, and the risk of roof leakage can be reduced. If this method is applied to an exposed waterproof and heat insulation integrated lightweight roof system, then the service life of the lightweight roof system can be extended, and maintenance costs can be reduced.
