  • Patent number: 11974338
    Abstract: In some implementations a system can be configured to reduce the burden of pairing user devices with playback devices. For example, all users (or user devices) who commonly operate within a particular environment (e.g., a home) can be configured as authorized users of playback devices within the particular environment. When one of the authorized users pairs a user device with a playback device, all of the user devices for all authorized users can be automatically paired with the playback device as a result of the single pairing. Thus, only a single authorized user is burdened with the pairing process in order to pair all authorized users with the playback device.

  • Patent number: 5947894
    Abstract: A disposable shield for positioning on a shaft of an endoscope to shield the user has a generally rigid, disposable shield body. The transparent plastic shield body has an opening in a medial portion thereof and a disposable elastomeric body, made from a closed cell plastic foam material, positioned in the opening. The elastomeric body has an undersized shaft opening in a medial portion thereof for contacting and securing the shaft of the endoscope therein, while permitting angular alignment of the shaft relative to the shield body. The shield body includes a convex upper portion on a protected side and a planar lower portion adjacent the convex upper portion. Ribbed edge portions provide additional stiffening to the shield body. Integrally formed sidewall portions extend outwardly from the protected side which define a generally cylindrical chamber for receiving the elastomeric body therein.

  • Patent number: 5876328
    Abstract: A surgical drape having a transparent, flexible tubular body for enclosing a non-sterile video camera includes a closed end and an opening adjacent the closed end. A flat reinforcing washer formed to the tubular body adjacent the opening defining an access opening into the tubular body for receiving a male threaded connection of a sterile camera coupler. The access opening of the reinforcing washer is sized to snugly fit the male threaded connection of the coupler so that the drape is readily secured to the coupler for providing an effective seal. When the coupler is screwed onto the camera, there is a clear optical channel between the camera and the coupler. With such an arrangement, the coupler is accessible from outside the drape. The drape separates the camera from the coupler and in operation, the coupler is sterilized prior to the start of the surgical procedure. As a result, both the coupler and the endoscope are easily accessible during the procedure.
