Publication number: 20110197684Abstract: An assembly of microcantilever-based sensors with enhanced deflections. A deflection profile of an ?-assembly can be compared with that of a rectangular microcantilever and a modified triangular microcantilever. Various force-loading conditions can also be considered. A theorem of linear elasticity for thin beams is utilized to obtain the deflections. The obtained defections can be validated against an accurate numerical solution utilizing a finite element method with a maximum deviation of less than 10 percent. The ?-assembly produces larger deflections than the rectangular microcantilever under the same base surface stress and same extension length. Also, the ?-microcantilever assembly produces a larger deflection than a modified triangular microcantilever. The deflection enhancement increases as the ?-assembly's free length decreases for various types of force loading conditions.Type: ApplicationFiled: April 27, 2011Publication date: August 18, 2011Inventors: Kambiz Vafai, Abdul Rahim A.

Publication number: 20110197685Abstract: The present disclosure provides devices, systems and methods for concentrating a fluid sample. A portable or hand-held concentrator is used to draw the fluid sample through a filter into an internal chamber, capturing target particles on the filter. An elution cartridge containing an elution fluid is used to recover the captured particles into a reduced fluid volume. The hand-held concentrator includes a tip, which, when opened, allows the hand-held concentrator to draw the fluid sample into the tip and through the filter wall into the internal chamber.

The elution fluid contains a foaming agent and is held under a head pressure of gas soluble in the elution fluid. The target particles are eluted from the filter into the reduced fluid volume using an elution foam that is formed when the elution fluid is released from the elution cartridge.Type: ApplicationFiled: February 16, 2011Publication date: August 18, 2011Applicant: InnovaPrep LLCInventors: David Scott Alburty, Andrew Edward Page, Alec D.

Publication number: 20110197721Abstract: A tool bit includes a hexagonal drive portion, a working end, and a shank interconnecting the drive portion and the working end. The shank includes an outer peripheral surface having a curvature in a plane including a central axis of the tool bit. The outer peripheral surface having the curvature includes a length in the direction of the central axis. A ratio of the length of the outer peripheral surface having the curvature to the length of the tool bit is between about 0.2:1 and about 0.7:1.Type: ApplicationFiled: November 6, 2009Publication date: August 18, 2011Inventor: Joseph M.

Publication number: 20110197723Abstract: A turning insert formed for chip-cutting metal machining of a workpiece that rotates in a direction of rotation at a first speed of rotation around a workpiece axis, the turning insert including a front surface, an envelope surface, and a circular cutting edge located where the front surface meets the envelope surface. The cutting edge extends around the front surface and lays in a plane that forms an angle ? with the envelope surface. A tool axis extends through the turning insert in a normal direction in respect of the plane, and the turning insert, during the chip-cutting metal machining, is formed to rotate around the tool axis at a second speed of rotation. The envelope surface forms a chip surface and is arranged to meet chips formed in the chip-cutting metal machining, and the chip surface includes chip breaking means.Type: ApplicationFiled: February 11, 2011Publication date: August 18, 2011Applicant: Sandvik Intellectual Property ABInventor: Sture SJÖÖ

Publication number: 20110197725Abstract: There is provided a punching unit having a structure permitting to reduce a force required for punching, permitting to lessen parts and permitting to punch holes through a member to be perforated at arbitrary positions thereof. The punching unit has a holder that holds one or plurality of sets of punches and dies. The holder is movable in an array direction in which a plurality of holes to be perforated through the member is arrayed. An eccentric cam is disposed above the holder in parallel with the array direction. The punches within the holder are driven toward the dies by rotating the eccentric cam regardless of moving positions of the holder. Thus, the punching unit can perforate a number of holes greater than the number of punches held within the holder by sequentially moving the holder and by rotating the eccentric cam.Type: ApplicationFiled: February 9, 2011Publication date: August 18, 2011Applicant: DAIDO KOGYO CO., LTD.Inventors: Kazuo NISHIMURA, Toshiyuki Majima, Megumi Ichikawa

Publication number: 20110197726Abstract: An electrically operated shaver includes a shaver housing and a cutter head. The cutter head is arranged on the shaver housing and includes at least one cutting device comprised of an outer cutter equipped with apertures and an under cutter. The cutters are driven into sliding relationship to one another by an electric drive, so that hairs entering the apertures are cut off by the cutting device. Provided on the cutter head adjacent to the cutting device is a supporting element which, like the cutting device, is engaged by an operator's skin surface during a shaving operation. Both the cutting device and the supporting element are mounted in the cutter head for displacement against the force of a spring. Means are provided for enabling a different distribution of the contact forces (F1, F2) to the cutting device and the supporting element.Type: ApplicationFiled: April 25, 2011Publication date: August 18, 2011Inventor: Bernhard Kraus
