    摘要： An implantable medical device has one or more feedthrough/electrode assemblies positioned around an outer periphery of the device. Each of the assemblies includes a ferrule and a feedthrough conductor that extends longitudinally through the ferrule. Each of the assemblies also includes a cover having an insulative body and an electrical contact that is mounted to the plastic insulator. The plastic insulator is positioned over an inner end of the assembly such that the contact is operatively coupled to the feedthrough conductor of the assembly. The cover can be oriented so as to be freely accessible for purposes of electrically connecting circuitry within the implantable medical device to the contact, and in turn, the feedthrough conductor. In turn, the wiring used in connecting the circuitry and the contact can be routed within the implantable medical device as desired.

    摘要： The invention discloses a subcutaneous electrode array or SEA for use in medical devices. The arrangement provides an enhanced capability for detecting and gathering electrical cardiac signals via the array of relatively closely spaced subcutaneous electrodes. Further, switching circuits, signal processors and memory to process electric cardiac signals are implemented to enable a leadless orientation-insensitive SEA scheme for receiving the electrical signal from the heart. The SEA is distributed over the perimeter of the implanted medical device and includes a non-conductive surround shroud of biocompatible material. The surround shroud is placed around the periphery of the case of the implanted medical device. Various configurations of recesses, each of which contain individual electrodes, are implemented to provide an enhanced signal to noise ratio for improved signal quality.

    摘要： Apparatus and method according to the disclosure relate to minimizing gaps between a substantially planar cardiac-sensing electrode and a shroud member utilizing a so-called interference-fit. For example, a relatively recessed area or aperture formed in an exemplary resin-based shroud member has slightly reduced dimensions relative to the electrode and requires compression forces during assembly (e.g., manually or in an automated process including a press, a tool or other means). The interference-fit promotes a very tight fit (or seal) between the metallic electrode and the resin-based shroud member and, importantly, minimizes gaps. Additionally, discrete interference structures promote fluid tight seals between the electrode and a recess or aperture adapted to receive the electrode.

    摘要： An institutional television system includes a source of standard broadcast composite television signals, an auxiliary source of RF carrier signals conveying sound information exclusive of video information, and a television receiver. The television receiver selectably processes the composite television signal including the sync component thereof in a normal mode, and selectably processes the auxiliary signals in an audio mode. The receiver comprises a video signal processing channel that is similarly energized in both the normal and audio modes. The video channel is controlled to enable light output from the kinescope of the receiver when the video sync component is present in the normal mode, and to inhibit light output from the kinescope when the video sync component is absent in the audio mode.

    摘要： A mounting arrangement for a circuit board on the neck of a cathode ray tube includes a guide member formed in the cathode ray tube base. The guide member is formed to have a surface extending perpendicular to the tube longitudinal axis. The circuit board incorporates a socket having a channel for receiving the guide member for aligning the socket on the tube base. A portion of a locking piece is inserted through a hole in the socket wall in order to abut the perpendicular surface of the guide member to prevent removal of the socket from the tube base. A second portion of the locking piece forms a hook which cooperates with the socket to prevent inadvertent removal of the locking piece.
