Abstract: This invention concerns a security lock for use with a lock unit. The security lock has a base, a casing in which the base is, in use, received, an elongate locking bolt, biasing means for urging the locking bolt towards its inoperative position, an externally accessible operating member for moving the locking bolt and a locking mechanism which is used to lock the bolt in its operative position. A securing mechanism is operable between a locked state in which the base and casing are locked to each other and a released state in which the base and casing are released from each other. A securing element is held captive such that it remains in position irrespective of whether the securing mechanism is in its locked or released state.

Abstract: A wireless radio frequency triggered signal acquisition device includes three orthogonal pick up coils in which voltages will be induced by a time varying, spatially varying magnetic field inside a chamber of an MRI scanner. A radio frequency detection circuit detects radio frequency pulses emitted by an MRI scanner and a wireless transmission circuit transmits data from the device, A 3-axis magnetometer is used for measuring magnetic flux in the chamber of the MRI scanner. A processor uses the detected radio frequency pulses to synchronize measurements taken by the magnetometer and pick-up coils to a time frame of a gradient driver hardware, thereby matching the measurements to a pulse sequence waveform. The processor further combines measurements of induced voltages in the orthogonal pick up coils and the magnetic flux with the pulse sequence waveform in order to solve for the instantaneous position and orientation of the device.
