Patent number: 7909918Abstract: An intense field dielectric air filtration system includes a perimeter frame for wall or ceiling mounting at the inlet of a return air duct for an air conditioning apparatus. A door including a grille disposed thereon is mounted for movement on the frame between working and non-working positions for access to an air filter unit, a pre-filter unit and an intense field particle charging unit. Contacts on the filter unit and the field charging unit engage cooperating contacts on an enclosure mounted on the frame when the door is closed to supply electrical power. An interlock is provided to interrupt power when the door is moved to an open position or the grille is removed. A control system disposed in the enclosure includes user control features accessible when the door is in an open position. An alternate embodiment includes a support frame for positioning the filtration system in ductwork or the like other than a return air inlet.Type: GrantFiled: August 15, 2007Date of Patent: March 22, 2011Assignee: Trane International, Inc.Inventors: Larry S. Bias, Kristin Lyn Schaefer, Shannon L. Smith, John Mark Hagan, Mark David Woodruff, Daniel Joseph Mitchell, Cassius J. Mullen, Timothy H. Cauley, Robert Beasley

Patent number: 7054154Abstract: A system and method for a multi-functional security mechanism in a docking station is disclosed. A docking station includes a hook to secure a portable computer to the docking station. A base plate includes a locked orientation and an unlocked orientation. A lever couples to the base plate to cause the base plate to actuate between the locked and unlocked orientation. A media bay, disposed in the docking station, receives a media device. A media bay lock pin couples to the media bay, engages the media device, and prevents removal of the media device from the media bay. A media bay lock couples to the base plate to release the media bay lock pin to engage the media device placed in the media bay. A media device sensor may associate with the media bay lock pin to permit the media bay lock pin to engage the media device.Type: GrantFiled: February 9, 2005Date of Patent: May 30, 2006Assignee: Dell Products L.P.Inventors: Cassius J.

Patent number: 6741462Abstract: A docking station ejection apparatus includes a housing having a movably mounted actuator. A first member is mounted in the housing and movable from a first position to a second position in response to movement of the actuator. An ejector is moved to an eject position in response to movement by the first member to the second position. A second member is movably mounted in the housing for movement between the first and second positions in response to movement of the first member to the second position. A catch member is mounted in the housing and is movable between a catch position and a release position. The catch member is moved in response to movement by the second member to the second position. A first resilient member urges the first and second members to the first position, and a second resilient member urges the catch member to the catch position.Type: GrantFiled: July 16, 2002Date of Patent: May 25, 2004Assignee: Dell Products L.P.Inventors: Kevin L.

Patent number: 6505487Abstract: A locking device (1) includes a first clip member (20) and a second clip member (40). The first and second clip members (20, 40) include a first and second clip base (21, 41), respectively. A first jaw (22) extends outwardly from the first clip base (21) whereas a second jaw (42) extends outwardly from the second clip base (41). The first and second clip members (20, 40) are connected together so that they may move with respect to each other between a closed position and an open position. In the closed position, the first and second jaws (22, 42) cooperate to form a locking loop (6). The locking loop (6) is adapted to fit through and lock with a locking feature (32) on an object to be secured. When the first and second clip members (20, 40) are moved to the open position, the first and second jaws (22, 42) are separated by an opening.Type: GrantFiled: September 21, 2000Date of Patent: January 14, 2003Assignee: Dell Products, L.P.Inventors: Michael R. Garel, David W. Grunow, Cassius J. Mullen
