Patent number: 8225658Abstract: Microstructures can be formed as patterned layers on a substrate and then erecting the microstructures out of the plane of the substrate. The microstructures may be formed over circuits in the substrate. In some embodiments the patterned layer provides resiliently-flexible members such as cantilevers or springs that can be buckled to permit an edge defined by the patterned layer to engage a surface of the substrate. In some embodiments deformation of the resiliently-flexible members results the edge being forced against the substrate. Such microstructures may be applied in a wide range of applications including supporting optical elements, sensors, antennas or the like out of the plane of a substrate. Examples of accelerometer structures are described.Type: GrantFiled: March 27, 2009Date of Patent: July 24, 2012Assignee: Simon Fraser UniversityInventors: Albert M.

Patent number: 6478838Abstract: An air treatment appliance for treating surrounding air including a body. A spider-mount mounted to the body has a motor mounted thereto in cantilever fashion. A fan attached to the motor may be a radial fan, and is operable to draw in surrounding air and cause it to flow through the appliance. A grommet between the motor and the spider-mount dampens vibrations from the motor. A filtering mechanism in the path of the airflow helps filter out undesirable material from the surrounding air. A radial airflow guide downstream from the fan efficiently guides the airflow to be expelled in a predetermined direction. The motor is at least partially accommodated by the spider-mount and the fan. The apparatus results in reduced noise and vibration during operation of the appliance.Type: GrantFiled: January 10, 2001Date of Patent: November 12, 2002Assignee: Whirlpool CorporationInventors: Anne Margaret McSweeney, James Jacob Morton, Jr., Dan Roger Maxwell, Guolian Wu, Murray Malone Mallard, Christopher Paul Campbell

Patent number: 5529277Abstract: A system is described which utilizes two perpendicular four-bar linkages coupled by a common plate to provide a translational-free flexible suspension having two rotational degrees of freedom about a desired point. One of the four-bar linkages is secured to a stationary "ground" structure, and the other linkage is attached to the object to be supported, such as a mirror. In one embodiment, two links of each of the two four-bar linkages are constructed from spring steel flexure elements which are rigid in all directions except about the rotational axis. The flexure elements thus comprise "revolute joints". Because the flexure elements function as spring hinges, no friction is encountered when the suspension is displaced or "pivoted".Type: GrantFiled: September 20, 1994Date of Patent: June 25, 1996Assignee: Ball CorporationInventor: Miroslaw A.

Patent number: 4620688Abstract: Apparatus for absorbing the energy associated with the displacements of pipes and other structural elements due to seismic and other dynamic forces. The apparatus includes a base on which a number of energy absorbing, plate-like members are mounted in cantilever fashion. The outer, free ends of the members are coupled to an arm which extends outwardly from the members and has an outer end connected to a pipe or other structural element whose displacement is to be controlled. Each member has convergent side edges on each side, respectively, of a narrowed central part, and the central parts of the adjacent members are substantially aligned with each other and with the outer end of the arm. Thus, when the pipe or structural element to which the arm is connected is displaced, the energy absorbing members bend, and uniformly yield, as the outer free end of the members remain in a plane substantially parallel to the plane of the fixed ends of the members.Type: GrantFiled: January 6, 1984Date of Patent: November 4, 1986Assignee: Bechtel International CorporationInventors: Mohamed Z.

Patent number: 4415137Abstract: Cantilever attachment method and apparatus are described. A resilient portion of a cantilever assembly holds a first part of an attachment device. The second part of the attachment device is positioned on a side of a post opposite the cantilever assembly. The attachment to the resilient means is positioned opposite an intermediate portion of a base on the cantilever assembly. The base lies against the post when assembled. The cantilever assembly is first tipped upward and the attachment is joined to the resilient portion. Tipping the cantilever assembly downward compresses the resilient portion. Continued rotation of the cantilever assembly downward slightly raises the cantilever assembly along the post and slightly relaxes the compression of the resilient portion, thereby creating an over-the-center clamp.Type: GrantFiled: April 2, 1982Date of Patent: November 15, 1983Inventor: John C.
