Abstract: Systems and methods for suppressing electrical noise in an electrocardiogram (ECG) signal obtained by at least one electrode and displayed on an ECG monitor are disclosed. The system includes a conductive material distinct from the at least one electrode and configured to contact a surface of a patient, and filtering circuitry connected in series between the conductive material and ground. The filtering circuitry may be configured to filter to ground the electrical noise present within the patient before it is received by the at least one electrode and is prevented from distorting the ECG signal that is displayed on the ECG monitor.

Abstract: A system for reading identifying information regarding a syringe assembly provided in a fluid injector is provided, the system including at least one syringe assembly having a syringe barrel with a distal end having a nozzle for expelling fluid therefrom and an open proximal end, the syringe barrel defining an interior volume, at least one indicator provided on at least a portion of an outer circumferential surface of the syringe barrel, the at least one indicator containing or associated with identifying information about the at least one syringe assembly, an injector having at least one syringe port configured to receive the at least one syringe assembly and to eject fluid therefrom, and a sensor module that activates the at least one indicator and receives information from the at least one indicator.

Abstract: An x-ray film changer includes a removably mounted, passive-type cassette having no film driving mechanism and comprising a film-receiving spiral guide plate extending within the cassette in excess of one and one-half 360.degree. turns. The cassette further comprises an anvil bar for reverse bending of the guide plate when the cassette is opened, to facilitate film removal, a light-blocking gate which uncovers a film feed-in slot in response to mounting of the cassette on a film exposure device, and a combination carrying handle-latch mechanism.
