Abstract: A device for coupling a vehicle to a trailer is provided. The device includes a base having a channel and a pair of sidewalls. The channel includes a mouth leading into a stop. The sidewalls are spaced apart from each other and the channel runs generally between the sidewalls. A catch is pivotally mounted between the sidewalls. The catch includes a mounting end, a catch end, and a contact surface. The catch end is pivotable between a first position, wherein the catch end abuts against the base; and a second position wherein the catch end is displaced from the base. The tow pin engages the contact surface of the catch and pivots the catch end towards the second position. The catch end returns to the first position so as to secure the tow pin between the catch end and the stop when the tow pin abuts against the stop.

Abstract: According to one aspect of the present disclosure, a computer-implemented method is provided for generating a reputation record and filtering electronic messages, each reputation record including a reputation score and a reputation key. The method includes receiving at least one incoming event notification, including a reputation key; determining, based on the reputation key, whether a corresponding reputation record exists; creating a new reputation record if the corresponding reputation record does not exist; determining a trust determination function based on the incoming event notification; calculating a reputation score based on the determined trust determination function, the incoming event notification, and an attribute associated with the reputation key; storing the calculated reputation score along with the reputation key in either the new reputation record or the corresponding reputation record; and filtering one or more electronic messages based on the calculated reputation score.
