    • A positioning system and method for determining a coordinate of an object may comprise a positioning transmitter system and a positioning receiver system. The positioning transmitter system includes at least four light sources and a master anchor to modulate the light sources to emit modulated light signals each having a modulation frequency. The positioning receiver system comprises a lens to focus the light signals onto an optical sensor, an envelope detector to receive a signal from the optical sensors and provide output signals corresponding to the modulation frequency, and positioning detection circuitry. The positioning detection circuitry receives calibration data; determines at least four phase difference of arrival (PDOA) pairs based on the output signals from the envelope detector; determines at least four phase corrected PDOA pairs based on the calibration data and the PDOA pairs; determines at least four linear distance differences based on the phase corrected PDOA pairs; and determines the coordinate of the object based on the linear distance differences and the calibration data.
    • 用于确定对象的坐标的定位系统和方法可以包括定位发射机系统和定位接收机系统。 定位发射机系统包括至少四个光源和主锚,以调制光源以发射各自具有调制频率的调制光信号。 定位接收器系统包括将光信号聚焦到光学传感器上的透镜,包络检测器,用于接收来自光学传感器的信号并提供对应于调制频率的输出信号和定位检测电路。 定位检测电路接收校准数据; 基于来自包络检测器的输出信号确定至少四个相位差到达(PDOA)对; 基于校准数据和PDOA对确定至少四个相位校正的PDOA对; 基于相位校正的PDOA对确定至少四个线性距离差; 并且基于线性距离差和校准数据确定对象的坐标。

    • A golf tee has a receipt portion (3) on top (where the golf ball rests prior to striking with a golf club), a cylindrical shaft portion (1), and a tapered bottom portion (2) for insertion into the ground for the purposes of anchoring and is not longer than four inches in length as set forth in Rule 1 1-1 by both the Royal and Ancient Golf Association (RA) in St. Andrews, Scotland, UK, and the United States Golf Association (USGA) in the United States of America. With Tee By The Numbers TM the cylindrical shaft portion has eight grooved rings (5) whereby a height Iimiter device (7) (an inverted cup design with squared edge and a hole in the middle) is used to adjust the height of the ball. The height Iimiter device snaps into any one grooved ring (spaced at least 1/4' apart). The cylindrical shaft has numbers one through eight, from top to bottom, either embedded or imprinted on each on the side of the tee shaft identifying each groove.
