  • Patent number: 11033781
    Abstract: Embodiments of putter-type golf club heads with adjustable loft and lie and methods of manufacturing of the same with adjustable loft and lie are generally described herein. These embodiments relate in particular to a putter-type club head with an adjustment portion that allows a user to change the loft and lie. The separate adjustment portions of the putter-type club head can couple the upper hosel to the body at a plurality of positions. An insert part of the adjustment portion has an upper section for receiving the upper hosel portion, a middle section, and a lower hosel portion. The sections of the adjustment portion can be coupled together by a fastener so that the sections are rotationally movable.

  • Publication number: 20210162279
    Abstract: A golf club head includes a body having a crown opposite a sole, a toe end opposite a heel end, a back end, and a hosel. The golf club head also includes a club face having a loft below a loft threshold in which increasing a coefficient of friction between a golf ball and the club face decreases the spin imparted on the golf ball after impact with the club face. A surface feature positioned on a portion of the club face is configured to increase the coefficient of friction between the golf ball and the club face.

  • Publication number: 20210138321
    Abstract: Some embodiments include club heads having reinforced club head faces. In one example, the club face comprises a reinforcement element such as a looped rib positioned on a rear surface of the club face to provide reinforcement. The club head further comprises an undercut that extends along the entire perimeter of the club face to provide increased club face bending. The combination of the reinforcement element and the undercut reinforces the club head while permitting the club face to bend. Other embodiments of related club heads and methods are also disclosed.

  • Patent number: 10996134
    Abstract: A method of diagnosing a leak in a coolant system of an automobile includes repeatedly measuring the coolant level within the coolant system at a pre-determined time interval, calculating a short term leak rate, wherein the short term leak rate is the rate of coolant leakage over a first pre-determined length of time, calculating a long term leak rate, wherein the long term leak rate is the rate of coolant leakage over a second pre-determined length of time, further wherein the second pre-determined length of time is longer than the first pre-determined length of time, identifying a coolant system leakage state based on a current coolant level within the coolant system, the short term leak rate, and the long term leak rate, and providing notification of the coolant system leakage state to an operator of the vehicle.

  • Patent number: 10857854
    Abstract: A method of identifying air flow faults within a cooling system of an automobile comprises measuring the temperature of coolant entering a heat exchanger for the cooling system, measuring the temperature of coolant leaving the heat exchanger, and measuring the temperature of ambient air that is flowing into the heat exchanger, calculating Actual Delta T by subtracting the temperature of coolant leaving the heat exchanger from the temperature of coolant entering the heat exchanger, calculating Expected Delta T, wherein Expected Delta T is a pre-determined value of an expected difference between the temperature of the coolant entering the heat exchanger and the temperature of the coolant leaving the heat exchanger, calculating Effective Delta T by subtracting Expected Delta T from Actual Delta T, and identifying a fault in the air flow through the heat exchanger based on the value of Effective Delta T.
