  • Patent number: 11806541
    Abstract: Systems and methods involve an intrathoracic cardiac stimulation device operable to provide autonomous cardiac sensing and energy delivery. The cardiac stimulation device includes a housing configured for intrathoracic placement relative to a patient's heart. A fixation arrangement of the housing is configured to affix the housing at an implant location within cardiac tissue or cardiac vasculature. An electrode arrangement supported by the housing is configured to sense cardiac activity and deliver stimulation energy to the cardiac tissue or cardiac vasculature. Energy delivery circuitry in the housing is coupled to the electrode arrangement. Detection circuitry is provided in the housing and coupled to the electrode arrangement. Communications circuitry may optionally be supported by the housing. A controller in the housing coordinates delivery of energy to the cardiac tissue or cardiac vasculature in accordance with an energy delivery protocol appropriate for the implant location.

  • Patent number: 6870562
    Abstract: An isolation system comprising: a substantially rectangular stationary frame; an imaging assembly including a curved platen for supporting image media and an exposure assembly for imagewise exposing a supported image media to produce exposed image media, wherein the imaging assembly has a substantial rectangular footprint and is sized to fit within the stationary frame; and a cable and spring assembly for suspending the imaging assembly from the frame to substantially isolate the imaging assembly from sources of external vibration.

  • Patent number: 6049682
    Abstract: Disclosed is a cartridge device for packaging an endless, organic photoreceptor belt of an electrophotographic printer. The cartridge device includes a substantially rigid, closed loop support structure and a resilient mechanism. The resilient mechanism engages the endless belt and releasably holds the belt against an inner surface of the support structure. The resilient mechanism holds the endless belt so that the belt substantially conforms to the shape of the support structure. The shape of the support structure essentially duplicates the configuration of the endless belt when the belt is mounted onto support rollers of the electrophotographic printer. By replicating the configuration of the support rollers, loading of a replacement photoreceptor belt onto the rollers is facilitated using the cartridge device. The cartridge device substantially protects the photoreceptor belt from inadvertent damage that would adversely affect the image reproduction quality of the replacement belt.

  • Patent number: 6014535
    Abstract: A cartridge device for packaging an endless, organic photoreceptor belt of an electrophotographic printer. The cartridge device is a closed loop support structure manufactured of a resilient material around which the endless belt extends. The resilient support structure has a belt loading configuration, that substantially duplicates the configuration of the endless belt when the belt is mounted onto support rollers of the electrophotographic printer. By replicating the configuration of the support rollers, loading of the belt onto the rollers is facilitated using the cartridge device. The resilient support structure also has a compact configuration that requires less volume than the belt loading configuration. The compact configuration of the cartridge device minimizes shipping volume and storage space requirements for replacement photoreceptor belts.
