Publication number: 20090058091Abstract: An energy harvester capable of providing motion from fluid flow includes a Magnus rotor defined by a cylinder driven by a motor causing the cylinder to rotate so that lift is created by the fluid flowing past the cylinder. A channel or system may be provided to direct the fluid flow to the cylinder. The rotating cylinder configuration is integrated into a mechanical device which is designed to transfer the lift into a mechanical motion to drive a generator. The mechanical motion due to the created lift is reversed by using a stalling mechanism and counter balanced mechanism. This creates a bidirectional motion which can be captured and used to drive a generator. The device can be utilized in either air or hydraulic environments. A modification of the energy harvester can be configured to utilize the electricity generate to produce hydrogen for use in fuel cells or for combustion.Type: ApplicationFiled: August 1, 2008Publication date: March 5, 2009Inventor: Joel S. Douglas

Publication number: 20080135629Abstract: The application discloses a security mark consisting of a plurality of layers, of which the cover layers are highly conductive films and the layers of the card core are films of varying transparency. One layer carries information, which can be read directly, if desired, above a security print, while the transparent conductive layer has an additional security markings, such as biometric or product identifiers marking which can be read conductively only with the aid of a special reader. All the layers consist of polymers, papers or mixtures which can be fused together to form a laminate which is fused together. The conductive layers form conductive traces which may be formed with single-walled or multi walled nano tubes or they can be formed from multiple layers or dispersions containing, carbon nano tubes, carbon nano tubes/antimony tin oxide, carbon nano tubes/platinum, or carbon nano tubes/silver, carbon, silver or carbon nano tubes/silver-cloride.Type: ApplicationFiled: January 7, 2008Publication date: June 12, 2008Inventor: Joel S.

Patent number: 7247144Abstract: A sampling device for sampling body fluid includes a lancet for making an incision, a capillary tube for drawing-up body fluid from the incision, and a test strip affixed to an upper end of the capillary tube for receiving the fluid. An absorbent pad can be disposed between the test strip and capillary tube for spreading-out the fluid being transferred to the test strip. An on-site analyzer such as an optical analyzer and/or an electrochemical analyzer can be mounted in the device for analyzing the fluid. Alternatively, a test strip can be slid through a slot formed in the bottom end of the device so that by passing the device against the skin after an incision has been formed, the test strip will directly contact body fluid emanating from the incision.Type: GrantFiled: July 3, 2003Date of Patent: July 24, 2007Assignee: Roche Diagnostics Operations, Inc.Inventors: Joel S.

Patent number: 7235056Abstract: A device for sampling body fluid includes a housing having a sleeve at a forward end thereof which is displaceable in response to being pressed against a user's skin to trigger the firing of a lancet. After the lancet is removed from the incision, the sleeve is repeatedly pressed against the skin to depress a ring of body tissue in surrounding relationship to the incision to express body fluid outwardly through the incision. A pusher member is then actuated to push a capillary tube through a front end of the housing for drawing-in body fluid. The lancet is a disposable lancet which includes a body supporting a skin-lancing member and the capillary tube. The disposable lancet passes through an upper end of a lancet carrier when being installed or removed. The device cannot be armed until the disposable lancet is installed in the housing, because the capillary tube functions to push a safety device to a non-safety position.Type: GrantFiled: April 23, 2002Date of Patent: June 26, 2007Assignee: Amira MedicalInventors: Brent G. Duchon, Joel S. Douglas, Jeffrey N. Roe, Ryszard Radwanski, Andrew M. Drexler

Patent number: 6878120Abstract: A sampling device for sampling body fluid includes a casing which is pressed against a skin surface to produce a seal therewith. A cocking mechanism is pulled rearwardly to place a lancing device in a cocked state. By releasing a trigger, the lancing device is driven forward to produce an incision in the skin, and then is retracted out of the incision. A plunger mounted on the cocking mechanism is then retracted to generate a negative pressure at the front end of the casing to draw body fluid from the incision.Type: GrantFiled: April 8, 2002Date of Patent: April 12, 2005Assignee: Roche Diagnostics Operations, Inc.Inventors: Jeffrey N.

Patent number: 6818180Abstract: Devices and methods for utilizing dry chemistry dye indicator systems for body fluid analysis such as glucose level in whole blood are provided by incorporating a porous membrane with a skin side which enables separation of whole blood and visually reading the indicator without removing the red blood cell portion of the blood from the membrane. The devices also enable visual reading of the indicator by use of a membrane or matrix which provides separation of whole blood in a lateral flow of the blood through the matrix from the input area to a test area of the matrix. The devices also provide for microtitration of fluid samples in fixed volumetric openings containing indicator reagent. Another aspect of the device provides a determination of hematocrit level in whole blood in combination with indicator indication of analyte concentration which can be compensated for the hematocrit level. The devices provided are low cost.Type: GrantFiled: June 14, 2001Date of Patent: November 16, 2004Assignee: Roche Diagnostics Operations, Inc.Inventors: Joel S. Douglas, Karen R. Drexler, James N.

Patent number: 6793633Abstract: A device and method for lancing a patient, virtually simultaneously producing and collecting a small fluid sample from a body. The device comprises a blood collection system including a lancing needle (16), drive mechanism (11), kneading or vibration mechanism (25), optional suction system (7), and sample ejection mechanism. The device is preferably sized to be hand-held in one hand and operable with one hand. The device can optionally contain integral testing or analysis component (83) for receiving the sample and providing testing or analysis indication or readout for the user. A method involves piercing the skin at a rapid rate, kneading the surrounding area by ultrasonic action, piezoelectric or mechanical oscillation to stimulate the blood flow from the wound, drawing the fluid using a pumping system.Type: GrantFiled: November 20, 2001Date of Patent: September 21, 2004Assignee: Roche Diagnostics Operations, Inc.Inventors: Joel S.
