Patent number: 7377494Abstract: The present invention is a family of portable humidifiers. Each of the portable humidifiers has a housing, a number of wick assemblies, and a fan. The housing has an air inlet, an air outlet and a reservoir for holding water. The number of wick assemblies are positioned within the housing to contact the water in the reservoir. The wick assemblies are arranged in parallel between the air inlet and the fan. The fan is provided within the housing for creating an airflow. The airflow enters the air inlet, passes through the wick assemblies for adding moisture to the airflow from the water in the reservoir, and exits through the air outlet. The number for at least one of the portable humidifiers is different from the number for another of the portable humidifiers. Preferably each of the portable humidifiers includes a wick frame seated within the reservoir for supporting the wick assemblies. Each of the wick assemblies preferably has a wick element and a button.Type: GrantFiled: March 29, 2006Date of Patent: May 27, 2008Assignee: Sunbeam Products, Inc.Inventors: Jon French, Robert A. Barker, Don Bryce, Francis E. Marino, Tsuguji Nakano, Gregory W. Bachmann

Patent number: 6523810Abstract: A humidifier includes a modular performance indicator that is removably attached to a grill of the humidifier air outlet. The performance indicator generally includes at least one humidity sensing means and a display. The humidity sensing means is positioned within the airflow for measuring the exit-relative humidity of the airflow and the display is coupled to the humidity sensing means for indicating when the humidifier wick requires replacement and/or the humidifier water supply requires refilling based upon the measured exit-relative humidity reaching a predetermined value.Type: GrantFiled: October 2, 2001Date of Patent: February 25, 2003Assignee: The Holmes Group, Inc.Inventors: Yigal Offir, Paul J. Powers, Jr., Robert A. Barker, Nalini Bihani, Ricardo Silveira, Danny J. Xu

Patent number: 5485932Abstract: A wall or room partition mountable modular rail rack component mounting system. The system includes wall racks shaped for interlocking engagement with each other at their opposite ends and cross stiffener members for placement between the wall rails to hold them in rigid space apart relationship. The wall rails each having a shaped opening at one end and a mating element at the other end thereof. The shaped opening and the mating element interlock with each other. The dimensions and spacings of openings and elements on the wall rails and rail racks for mounting thereon provide for rail racks mounted in vertically aligned closely space relationship that gives uninterrupted rail rack placement.Type: GrantFiled: May 3, 1994Date of Patent: January 23, 1996Assignee: Digital Equipment CorporationInventors: Michael Romm, Robert A. Barker, Stuart K. Morgan

Patent number: 5285007Abstract: A containment system for significantly reducing the emission of high frequency electromagnetic waves from a computer system into the external environment. The containment system includes the combination of two enclosures and a shielding assembly. One of the enclosures is associated with the high frequency components and the other with the low frequency components of the computer system. The shielding assembly is positioned between the two enclosures to prevent high frequency electromagnetic waves from passing from one chamber to the other over the connection between the two chambers.Type: GrantFiled: February 3, 1992Date of Patent: February 8, 1994Assignee: Digital Equipment CorporationInventors: Alfred E. Deluca, Jeffrey M. Lewis, Cosmo L. Leo, Thomas J. Orr, David T. Symmes, Robert A. Barker

Patent number: 4896166Abstract: A print head assembly includes the feature of snap-in, tool-less replaceability. The print head is intended for an application where extended use is expected and replacement, due to wear, will be necessary by nontechnical users of the printing system. In one embodiment, the print head utilizes two pins which slide into slots formed in the printer body. The print head is free to pivot about the two pins and is urged against a platen by the force of bias springs and a loaded pin. The loaded pin engages with, and forces upwrd on the heat-radiating fins extending from the bottom of the print head. Shelves formed in the printer body cover engage the two pins of the print head and force the print head, against the forces of the bias springs, into a proper alignment position when the cover is closed. This allows firm engagement of the print head with the platen, and proper alignment thereof, without fixing the print head to a mounting structure.Type: GrantFiled: March 30, 1988Date of Patent: January 23, 1990Assignee: Dataproducts CorporationInventors: Robert A. Barker, Jonathan J. Burnard, Thomas A. Davis, Danny J. Prats, Melanie L. Seat
