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.

Abstract: Systems, methods and apparatus for wireless charging are disclosed. An apparatus has a wireless charging apparatus has a battery charging power source coupled to a charging circuit, a plurality of charging cells configured to provide a charging surface, and a controller. The controller may be configured to provide a pulse to the charging circuit, detect a frequency of oscillation of the charging circuit responsive to the pulse or a rate of decay of the oscillation of the charging circuit, and determine that a chargeable device has been placed in proximity to a coil of the charging circuit based on changes in a characteristic of the charging circuit. The pulse may have a duration that is less than half the period of a nominal resonant frequency of the charging circuit.
