Incisional Breast Biopsy Device

US Patent:
6551253, Apr 22, 2003
Filed:
Feb 2, 2001
Appl. No.:
09/776444
Inventors:
Dustin Worm - Delton MI
Martin Flatland - Kalamazoo MI
Mark Tomandl - Hastings MI
Mark A. Penrod - Delton MI
Warren D. Lun - Battle Creek MI
Assignee:
Imagyn Medical Technologies - Irvine CA
International Classification:
A61B 1000
US Classification:
600564, 600567, 606170
Abstract:
A biopsy device is provided which includes a localization needle having a guide wire preloaded into the biopsy device. The device includes a stylet having a blade for transecting and separating tissue. The device further includes a cannula for cutting a core of tissue and a garrote wire mechanism for cutting a transection of tissue transverse to the core cut by the cannula. The garrote wire is activated by a trigger mechanism which is locked out by a lockout feature within the device until the garrote wire has been advanced around the core of tissue cut by the cannula.

Chair Having A Seat With Adjustable Front Edge

US Patent:
6890030, May 10, 2005
Filed:
Dec 9, 2002
Appl. No.:
10/314767
Inventors:
Larry Wilkerson - Comstock Park MI, US
Gardner Klassen - Ada MI, US
Mark Tomandl - Allendale MI, US
Assignee:
Haworth, Inc. - Holland MI
International Classification:
A47C003/025
US Classification:
29728411, 297316
Abstract:
A chair is provided having a seat with a resiliently deflectable shell defining a front portion thereof. The front shell is deflectable downwardly in response to the user. An adjustment mechanism is provided which controls the deflected position of the front shell section to provide for controlled deflection of the seat which adjusts the effected length of the seat while also providing for user responsive deflection of the seat.

Chair Having A Suspension Seat Assembly

US Patent:
6983997, Jan 10, 2006
Filed:
Jan 2, 2003
Appl. No.:
10/336045
Inventors:
Larry A. Wilkerson - Comstock Park MI, US
Mark G. Tomandl - Allendale MI, US
Keith Page - Holland MI, US
Gardner Klassen - Ada MI, US
Assignee:
Haworth, Inc. - Holland MI
International Classification:
A47C 7/02
US Classification:
29745256, 29745257, 29745213
Abstract:
A suspension seat assembly for an office chair is provided which has a support frame and a suspension fabric connected about its periphery to the frame. The fabric is first laid across the frame and then the peripheral edges of the suspension fabric are secured in place on the frame by over-molded trim. The suspension fabric may also be formed as a multi-layer composite comprising an aesthetic upper layer, a stretchable suspension layer and an optional cushion layer therebetween. The suspension layer is a fabric-type material which is preferably air permeable and resilient to support the weight of a chair occupant.

Appl. No.:
11/124973
Inventors:
Larry Wilkerson - Comstock Park MI, US
Gardner Klassen - Ada MI, US
Mark Tomandl - Allendale MI, US
Assignee:
Haworth, Inc. - Holland MI
International Classification:

Stored Energy Control Mechanism

US Patent:
7631938, Dec 15, 2009
Filed:
Aug 22, 2007
Appl. No.:
11/843422
Inventors:
Mark G. Tomandl - Cedar Springs MI, US
Assignee:
Grand Rapids Controls Company, LLC - Rockford MI
International Classification:
B60N 2/10
US Classification:
297336, 297326
Abstract:
An energy storage mechanism for folding seats for vehicles and the like includes an energy-storing component such as a spring that assists in moving the seat or other component. The mechanism provides for relatively small user input forces and distances, yet provides a relatively large force acting over a relatively large distance as an output of the mechanism. The mechanism may be configured to provide for a single user input/release, without requiring powered actuators or the like.

Compensator For Cables

US Patent:
7841257, Nov 30, 2010
Filed:
Jun 11, 2008
Appl. No.:
12/136925
Inventors:
Mark G. Tomandl - Cedar Springs MI, US
Assignee:
Grand Rapids Controls Company, LLC - Rockford MI
International Classification:
F16C 1/22
US Classification:
745015R
Abstract:
A compensator for cables includes a housing and a spring wrapped around inside the housing to form a loop. An inner strand of a Bowden cable or the like extends through the coil spring, and thereby forms a loop. The looped configuration of the coil spring provides a higher effective spring constant, and thereby permits a smaller coil spring to be used. The dimensions of the compensator can also be reduced, thereby reducing the space required for the compensator.

Control Mechanism

US Patent:
8066327, Nov 29, 2011

International Classification:
B60N 2/04
US Classification:
297326, 2973781
Abstract:
An energy storage mechanism for folding seats for vehicles and the like includes an energy-storing component such as a spring that assists in moving the seat or other component. The mechanism provides for relatively small user input forces and distances, yet provides a relatively large force acting over a relatively large distance as an output of the mechanism.
