CPC Class H04W

Systems and methods for facilitating safe vehicle operations, such as reducing illegal passings, avoiding possible collisions, and assisting road users around a vehicle are provided. The system uses a smart algorithm to perform negotiations between the vehicle, e.g., a school bus, and other road users, e.g., road vehicles, bicycles, scooters, etc. The method may include capturing image data of the surroundings of the school bus to identify violations within a proximity of the school bus such as children jay-walking and vehicles illegally passing the school bus when the stop arm is raised. The captured data may be recorded and shared with the school bus, other road users, or local authorities.

A method and system for identifying and/or classifying a user of a vehicle based on sensory data measured by sensors of a cellular mobile device, the sensors at least comprising an accelerometer and a gyroscope. The mobile device measures gravitational acceleration movement sensory data by the accelerometer based on measuring parameters obtained from the accelerometer, vehicle entering or exiting movement patterns of the user being detected from the acceleration movement sensory data at least comprising pattern for base axis and degree of rotation associated with a vehicle entrance or exit of the user. The detected vehicle entering or exiting movement patterns of the user trigger as input features the recognition of a vehicle entering or exiting movement of the user by performing a decision-tree classification on the input features to rule out whether the user entered or exited from a left or right side of the vehicle.

A lanyard system for a marine vessel propelled by at least one propulsion device includes an operator device worn by an operator of the marine vessel, a receiver device at a helm area of the marine vessel, wherein the receiver device is configured to detect whether the operator is within a permitted zone with respect to the helm area, and a control configured to generate a lanyard event when the operator is not detected within the permitted zone and, upon generating a lanyard event, reduce an rpm of the propulsion device at a pre-set reduction rate to an idle rpm.

The present invention relates to a venturi device for a combined sewage overflow system, the venturi device comprising: a body defining a fluid passageway therethrough, the body having a first end portion defining a fluid inlet; a second end portion opposing the first end portion, the second end portion defining a fluid outlet and an opposing venturi inlet in fluid communication with the fluid outlet: and a mid-portion located between the first and second end portions; and a venturi pipe located between the first fluid outlet and the venturi inlet and in fluid communication with both, wherein the venturi pipe is narrower in cross section than the venturi inlet, and wherein the fluid inlet comprises an intake funnel that decreases in width in a direction towards the fluid passageway. The present invention further provides a CSO system including such a venturi device.
