Abstract: A cable management system is used in neurological monitoring and imaging procedures, particularly MRI. The system enables quickly disconnecting and quickly and accurately reconnecting the patient to the neurological monitoring equipment. The cable management system uses plural color-coded, two-part, cable pairs that include an electrode cable and an extension cable in each pair. The electrode and the short electrode cable remain attached to the patent during monitoring while the extension cable is disconnected and removed. A plug and socket combination that connects in a preselected orientation that enables the two parts to be quickly and accurately disconnected and reconnected. Metal is minimized in the electrode and electrode conductor in part by its short length, it thinness, the use of metal coating on plastic electrodes, and the use of alternative conductive materials.

Abstract: A radio receiver system for receiving double sideband signals from a plurality of antennas (N1,N2) having different reception characteristics detects a reduction in power in one of the sidebands of a received signal, due to multiple path reception or other disturbances. The system then selects for use by the receiver a signal from an antenna less affected by the disturbances.

Abstract: A radio receiver antenna system for overcoming multiple path propagation fading, includes an antenna arrangement which provides respectively at two terminals in response to a given transmitted signal, two signals at the frequency of the transmitted signal as are respectively produced by two antennas having different reception characteristics. A combining circuit is operative for producing an output at the frequency of the transmitted signal by combining the signals produced at said terminals in such manner that the output is significant for substantially all values of the relative phase of the two signals. The combining circuit includes an inductive winding to opposite ends of which the two signals are respectively applied. An output is derived from a tapping point on the winding or from a second winding, inductively coupled to said first-mentioned winding. A first output is preferably derived from a tapping point on the first-mentioned winding.
