Abstract: A multi-node motion measurement and analysis system comprises at least one motion measurement module and a receiver unit. The motion measurement module is bound to a hand-held sports appliance through an adjustable fixture or being bound to a human body. A binding position on the human body is rearrangeable based on different measurement requirements. The motion measurement module comprises a sensor module configured to measure information of acceleration, angular velocity and magnetic force, a first microprocessor module connected to the sensor module and configured to generate information of orientation, and a first RF module configured to receive the information of acceleration, angular velocity, magnetic force and orientation and transmit the received information to the receiver unit.

Abstract: A multiple enclosure security storage apparatus for storing valuable items, including a housing, enclosures, a locking apparatus associated the enclosures, and an unlocking control system connected to the locking apparatus. Each enclosure defines a storage compartment adapted to store valuable items, and is movable between closed and open configurations. In the closed configuration, access to the storage compartment is obstructed. In the open configuration, the storage compartment is accessible. The locking apparatus moves each enclosure between locked and unlocked configurations. In the locked configuration, the enclosure is secured in the closed configuration. In the unlocked configuration, the enclosure is movable between the closed and open configurations. The unlocking control system disables unlocking of the enclosures when any one enclosure is in the unlocked configuration, and enables a selected enclosure to be unlocked only when all of the enclosures are in the locked configuration.
