Abstract: An apparatus comprises an electrical device or component (40) and a radio frequency shield arranged to shield the electrical device or component. The apparatus is disposed in a radio frequency (Bi) field generated by a magnetic resonance scanner and in time varying magnetic field gradients generated by the magnetic resonance scanner (10). The radio frequency shield includes an electrically conductive sheet or layer having openings suppressing time varying magnetic field gradient induced vibration of the radio frequency shield.

Abstract: A robust MR compatible ECG monitor (40) includes a connector (50) for connecting ECG electrode leads (44) to an internal circuit board (52). The connector (50) includes connector pins (54) that run parallel to the circuit board (52) and tangentially contact solder pads (56) of the circuit board (52) at the edge of the circuit board (52), eliminating sharp or right angle turns in conduction paths. The connector prevents movement of the connections due to mechanical stresses in all ranges of motion relative to four degrees of freedom, including translation, pitching, yawing, and rolling.

Abstract: A patient monitoring system detects physiological signals from a patient during an MRI examination. The patient monitoring system wirelessly transmits data associated with the physiological signals to a remote base unit. The wireless transmission of data is carried out in a manner to not be disruptive to the MRI examination. The patient monitoring system has a removable, MRI magnet compatible battery.

Abstract: A base unit operable with a wireless patient monitoring unit used to acquire physiological data during an MRI examination is constructed to have a detachable display unit. The detachable display unit wirelessly communicates with the base unit when in a roving mode. The detachable display unit may also have a magnetically-hardened power supply that does not saturate during an MRI examination. Such a magnetically-hardened power supply allows the display unit to operate when proximate or in the magnetic field generated by an MRI machine during an MRI examination.

Abstract: A wireless patient monitor for MRI provides for on-board filtering of physiological signals from the patient to provide improved assessment and processing of MRI noise before the signal is affected by the transmission process. A system of powering of a wireless patient monitor using capacitors is also provided.

Abstract: A stay assembly comprising a tether, a tether retracting mechanism carried by an animal collar and a slotted clip body carried by the belt of a person. One end of the tether is secured to a spool biased by a spring of the retracting mechanism and the other end of the tether has an enlarged member which is quickly attachable to and releasable from the slot of the belt clip body in which it is securely held by the tension applied to the tether by the spring biased spool. The animal collar may be attached to a wall of the retracting mechanism or pass through a channel within the housing of this mechanism.
