Abstract: A device and method for assembling an electronic golf ball are described. The device may include a printed circuit board, a wire wrapped around a ring-shaped bobbin, where the ring-shaped bobbin includes four legs, two on each side of the ring-shaped bobbin, with the printed circuit board inserted into the ring-shaped bobbin. This assembly, an electronic apparatus, is placed in a mold, with at least one of the four legs in contact with walls of the mold, the legs centering the electronic apparatus in a center of the mold. An inner layer material is inserted in the mold creating an inner core assembly. The inner layer assembly is removed from the mold and covered with a stiff spherical core and an outer golf ball cover layer, to form the golf ball.

Abstract: A conducted electrical weapon (“CEW”) launches wire-tethered electrodes from multiple cartridges to provide a stimulus signal through a human or animal target to impede locomotion of the target. The CEW may detect the quality of the electrical coupling (e.g., connection) of pairs of electrodes with the target. In accordance with the quality of the connections, the CEW may provide pulses of a stimulus signal to the various connections between electrode pairs in accordance with a sequence. The sequence may provide pulses at a first maximum pulse rate to any one connection to increase the likelihood of inducing neuromuscular incapacitation (“NMI”) and to save energy. The sequence may provide pulses to all connections at a second maximum pulse rate to increase the likelihood of inducing NMI and to save energy.

Abstract: A system and method for measuring golf ball trajectory characteristics is disclosed. A device may collect a user and ball magnetometer and accelerometer frame of reference vectors. A device may calculate frame of rotation coefficients from the user magnetometer frame of reference vector, the user accelerometer frame of reference vector, the ball magnetometer frame of reference vector, and the ball accelerometer frame of reference vector using a Kabsch Algorithm. A device may collect a ball magnetometer time series matrix from the ball magnetometer as the ball is in flight. A device may process the ball magnetometer time series through a Rodrigues Rotation Formula using the frame rotation coefficients to create a rotation vector. A device may calculate a prior vector difference and a second prior vector difference. A device may calculate the spin axes by multiplying the prior vector difference by the second prior vector difference.
