Patent number: 9658423Abstract: Embodiments of the invention are directed to a springless athermal lens assembly. In one embodiment, a spacer of a springless athermal lens assembly may compensate for defocus of the camera system due to thermal expansion of the lens assembly through the coupling of a spacer to an inner barrel and an outer barrel. The inner barrel comprises a lens cell assembly and a body. The outer barrel comprises a body. The spacer comprises a body having an inner surface and an outer surface. The outer surface of the spacer body is configured to be physically coupled to outer barrel body and the inner surface of the spacer body is configured to be physically coupled to the inner barrel body. A retainer ring is configured to engage with the outer surface of the spacer body and provide a radial force against the outer surface of the spacer body to securably engage the inner surface of the spacer body with the inner barrel body.Type: GrantFiled: September 29, 2015Date of Patent: May 23, 2017Assignee: DRS Network & Imaging Systems, LLCInventors: Eric J.

Publication number: 20090205817Abstract: A packer assembly comprises a tubular member and a packer system that circumferentially overlies the tubular member. The packer system includes end portions and a central portion disposed between the end portions. The central portion and the end portions are formed of material that swells when contacted with a swelling fluid. The central and end portions are constructed to swell upon contact with the swelling fluid so that the central portion swells to a diameter defined by a wall of the wellbore more rapidly than the end portions. In such a configuration, the central portion of the packer system can be fully swollen prior to the full swelling of the end portions.Type: ApplicationFiled: February 6, 2009Publication date: August 20, 2009Inventors: Eric J.
