Abstract: The present disclosure provides systems and methods associated with a golf tee configured to impart a spin to a golf ball prior to impact between the golf ball and the golf club face. The golf tee includes a retention mechanism configured to releasably secure a golf ball to a contact surface of the golf tee while a rotation mechanism rotates the golf tee or a spin mechanism spins the golf ball, thereby imparting spin to the golf ball. The golf tee may further include a processing unit configured to control the retention mechanism and rotation mechanism or spin mechanism. The processing unit may communicate with various external or local sensors, for example, a swing sensor, an environmental sensor, or the like, to control the golf tee to spin the golf ball to achieve a particular post impact trajectory.

Abstract: Disclosed are systems and methods associated with a golf tee configured to reduce or eliminate spin imparted on a golf ball due to friction between a contact surface of the golf tee and the golf ball. In one embodiment, the golf tee includes a retracting mechanism to retract the support member of the golf tee prior to impact between the golf club face and the golf ball, at least one swing sensor to measure motion parameters of an approaching golf club, and a processing unit to control the retracting mechanism based on the measured motion parameters. In another embodiment, the golf tee includes a contactless support mechanism to support the golf ball, a position sensor to detect a position of the golf ball, and a processing unit to control the support mechanism, based on data from the position sensor, to manipulate the position of the golf ball.

Abstract: Disclosed is a golf tee configured to control spin imparted on a golf ball due to friction between a contact surface of the golf tee and the golf ball. In one embodiment, the golf tee includes a plurality of support members to support a golf ball, wherein contact between the golf ball and the plurality of support members is asymmetrically distributed between a first contact area and a second contact area. In another embodiment, the golf tee includes a two-part shaft slideably coupled together and an adjustable resistance mechanism to provide a resistive force between the two parts of the golf tee, wherein the resistive force opposes the sliding together of the two parts. The resistance mechanism may be manually or automatically to control spin imparted to the golf ball due to friction between a contact surface of the golf tee and the golf ball.
