Abstract: An electrocardiogram (ECG) extension cable includes a first connector configured to be electrically coupled to a physiological monitoring device, a second connector configured to be electrically coupled to an ECG lead set including a processor, an input/output (I/O) wire configured to transmit data between the physiological monitoring device and the processor, a ground wire that establishes a ground path between the first connector and the second connector, a series protection element coupled in series along the ground wire, a bypass path coupled to the ground wire in parallel to the series protection element, and a switching element arranged along the bypass path and configured to redirect the ground path along the bypass path, thereby bypassing the series protection element.

Abstract: A system for updating a location of a target with an RFID device in response to detected motion of the target includes a server and tracking modules. The server stores identifying information for RFID devices and locations associated with the devices. The tracking modules are positioned in predetermined locations and communicate with the server. Each tracking module includes a motion processing module and an RFID reader. In response to motion detected by a motion processing module, the RFID reader detects identifying information for an RFID device neighboring an RFID reader and transmits the information to the server.

Abstract: A lock control system includes a detection unit positioned proximate to a lock, an RFID device neighboring at least one RFID antenna, and an RFID reading system detecting identifying information of the RFID device when the detection unit detects an event. The system also includes at least one microcontroller that determines, based on the identifying information, whether to grant the RFID device access to an area secured by the lock and instructs an actuator to unlock the lock when the RFID device is granted access.

Abstract: A method of imaging using magnetic resonance includes administering hyperpolarized noble gas to a subject in a region to be imaged, applying a magnetic field of a magnitude between about 0.0001 Tesla and about 0.1 Tesla to the subject at least in the region of the subject to be imaged, detecting a spatial distribution of magnetic resonance signals of the hyperpolarized noble gas in the subject, and producing a representation of the spatial distribution.

Abstract: The present invention uses a ventilator and a series of valves to deliver a special gas into a patient. The present invention finds use in the field of MRI imaging. Attached to the tube extending from the ventilator to the patient is attached a first valve. This valve alternately connects the patient to the ventilator then to a supply of the special gas. Between the first valve and the supply of gas is a second valve, which controls the pressure between the first valve and the second valve caused by the special gas. The supply of special gas is connected to the second valve. A flow regulator controls the rate at which the special gas enters the patient. A computer is also attached to the ventilator and valves to synchronize the opening and closing of the valves and the operation of the ventilator with the patient's respiratory cycles.
