Abstract: A billiard table cleaning device for autonomous cleaning of a playing surface of a billiard table includes a housing, which defines an interior space and which has at least one linear side. A drive unit is engaged to a bottom of the housing and is configured to selectively motivate the housing across a playing surface of a billiard table. A vacuum assembly is engaged to the housing and is positioned in the interior space. The vacuum assembly suctions air and debris, such as chalk dust, through slots positioned in the bottom and expels filtered air through vents positioned in or proximate to a top of the housing, thereby cleaning the playing surface.

Abstract: An implantable pulse generator is disclosed herein. In one embodiment, the implantable pulse generator includes a housing, a feedthru, and a header. The housing includes an electronic component housed within the housing. The feedthru is mounted on the housing and includes an electrical insulator and a lead connector block. The electrical insulator includes a header face and a housing face opposite the header face. The lead connector block extends from the header face of the electrical insulator. The housing face faces in the general direction of the electronic component. The lead connector block is in electrical communication with the electronic component. The header includes an electrically insulative barrier and an outer covering. The electrically insulative barrier includes a feedthru face and a cavity. The feedthru face abuts the header face and the lead connector block resides in the cavity. The outer covering extends over the electrically insulative barrier.
