Patent number: 8961781Abstract: A filter status module for use with a container based filtration device includes a dispensing sensor and a user interface communicatively coupled to a processing unit. The processing unit counts a number of dispensing events, duration and/or angle of tilt signaled by the dispensing sensor and outputs a filter status on the user interface as a function of the number of dispensing events, duration and/or angle of tilt. The processing unit may further track an elapsed period of time from insertion of a new filter and output the filter status as a further function of the elapsed period of time.Type: GrantFiled: September 29, 2011Date of Patent: February 24, 2015Assignee: Brita LPInventors: Benjamin Ma, Rick T. Nishijima, John W. Jamieson, Edward M. Buckley, Teruo Hishiki, David Dycher, Ho Pun Chung

Patent number: 5927461Abstract: A mechanical device for automatically positioning a closure plate for sealing the opening created by the folding of adjacent segments of an articulated chute to thereby prevent undesired discharge or leakage from the chute is provided. The device, which is particularly useful on cement trucks, includes a closure plate rotatably connected to one segment of the chute and disposed to articulate upon an adjacent segment of the chute so that the closure plate seals the opening when the chute is in a folded configuration and, when the segments are unfolded to deliver a charge, rotates to a position clear of the discharge path. The device also includes means for sealably biasing the closure plate toward the opening when the segments are folded and for biasing the closure plate away from the discharge path when the segments are in an unfolded position.Type: GrantFiled: January 17, 1997Date of Patent: July 27, 1999Assignee: Forfam IncorporatedInventor: John W. Jamieson

Patent number: 5845350Abstract: An infant environmental transition system provides an infant with controlled simulated movements encountered by an infant in an intrauterine environment. The system includes a suspension system having a plurality of flexures coupled between a base plate and a moving mattress platform. A cam shaft assembly includes a groove that engages a linear follower connected to the moving platform so that the follower moves along the groove while the cam shaft assembly rotates to move the linear follower, and thereby reciprocate the moving mattress platform in a longitudinal direction. Alternatively, a rotating crank assembly translates crank rotation to reciprocating movement of the mattress platform.Type: GrantFiled: February 16, 1996Date of Patent: December 8, 1998Assignee: Infant Advantage, Inc.Inventors: Gerald V. Beemiller, John W. Jamieson, Richard D. Propper, Dean L. Kamen, Jeffrey I. Finkelstein, Dennis C. Waite

Patent number: 5385153Abstract: An infant environmental transition system and method provides an infant with a controlled, healthy transition from an intrauterine environment to the extrauterine environment, and includes a housing within which the infant is supported by a soft, form-fitting bolster system. The bolster system is comprised of one or more pads, or bolsters, arranged such that they can be placed about an infant. A gentle but firm pressure is exerted on the infant by the bolster or bolsters through the use of straps or by the use of a U-shaped spring covered partially or completely by a bolster or bolsters. This pressure offers a reduction of an infant's stress level, as well as physical stabilization of the infant. Environmental conditions provided within the housing include simulated motions, sounds and tactile sensations resembling the intrauterine environment. A suspension and drive system controls the degree of movement imparted to the housing and to an infant supported therein.Type: GrantFiled: August 12, 1992Date of Patent: January 31, 1995Assignee: Infant Advantage, Inc.Inventors: John W. Jamieson, James D. Gatts

Patent number: 5183457Abstract: An infant environmental transition system and method provides an infant with a controlled, healthy transistion from an intrauterine environment to the extrauterine environment, and includes a housing within which the infant is supported by a soft, form-fitting bed. Environmental conditions provided within the housing include simulated motions, sounds and tactile sensations resembling the intrauterine environment. A suspension and drive system controls the degree of movement imparted to the housing and to an infant supported therein. The resulting motion closely approximates the motion experienced by the fetus while the mother is walking. The sound profile simulates intrauterine cardiovascular and gastrointestinal sounds. The system simulates day and night variations in motions and sounds, integrates changes to the environment over time toward the natural extrauterine environment, and may respond to infant activity or other inputs at various intervals.Type: GrantFiled: April 16, 1990Date of Patent: February 2, 1993Assignee: Infant Advantage, Inc.Inventors: James D. Gatts, Edward M. Buckley, John W. Jamieson

Patent number: 4502800Abstract: A printer having a print wheel rotatable on a carriage. The carriage is guided for movement parallel to a platen. The printer may print at either a fast speed for draft quality output, or a slower speed for highest quality output. The lesser quality of output produced at the fast speed is more than adequate for draft documents.Type: GrantFiled: July 8, 1982Date of Patent: March 5, 1985Assignee: 501 Qume CorporationInventors: John W. Jamieson, Sen L. Lee, Suhdok D. Moon

Patent number: 4428695Abstract: A cartridge which contains two spools. The supply spool has wound about it a printing ribbon and the take-up spool being used for wrapping the used ribbon. The cartridge has a ribbon exit at one location and a ribbon entry at a remote location to define a path for the ribbon to pass therealong. Two drive gears are engaged with each other and a pressure roller. The drive gears are located and their lower portions are configured to engage the respective drive shafts of various printers. When the first drive gear is driven by a printer, the second gear, which includes the drive wheel, rotates in the opposite direction of the drive shaft of the printer. When the second gear is driven, the integral drive wheel rotates in the same direction as the drive shaft of the printer. The pressure roller is provided with internal flexible spokes, or springs, and provides a self-adjusting bias against the drive wheel to drive the ribbon and provides an extremely efficient pinching action.Type: GrantFiled: May 12, 1982Date of Patent: January 31, 1984Assignee: Qume CorporationInventor: John W. Jamieson

Patent number: 4396307Abstract: A sheet feeder for an impact daisywheel type printer is interconnected with an existing system by reconnecting the ASCII type data cable to the sheet feeder. The internal logic of the sheet feeder is cabled to the printer and provides for all necessary automatic control. The sheet feeder also includes a mechanical bail control which opens the bail to allow for automatic feeding of the paper around the platen.Type: GrantFiled: April 7, 1978Date of Patent: August 2, 1983Assignee: Qume CorporationInventors: Franklin B. Shah, John W. Jamieson

Patent number: 4259025Abstract: An impact printer, for example, of the daisy wheel type with plotting capability is provided by utilizing a cartridge which instead of an inked ribbon has a marking pen mounted through the cross-section of the cartridge and is selectively engageable against the paper by the use of the existing ribbon lift mechanism.Type: GrantFiled: September 29, 1978Date of Patent: March 31, 1981Assignee: Qume CorporationInventor: John W. Jamieson

Patent number: 4204779Abstract: An impact printer of the daisywheel type mechanically links together two daisywheel printer carriages so that the total number of different characters that can be printed is doubled. Suitable coordination logic provides for operation in a first concurrent (or parallel) mode where the user's software looks ahead to provide for continuous printing along a single line. The other mode of operation is sequential where the twin print heads are substantially transparent to the user's system and thus the appropriate print head automatically positions itself to a printing position.Type: GrantFiled: April 7, 1978Date of Patent: May 27, 1980Assignee: Qume CorporationInventors: Sen L. Lee, Franklin B. Shah, John W. Jamieson
