  • Patent number: 7901363
    Abstract: 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.

  • Publication number: 20110046515
    Abstract: A sample of a body fluid such as blood or interstitial fluid is obtained from a body by lancing a portion of a user's skin, preferably in an area other than a finger tip, to form an incision. After the needle has been removed from the incision, a force is applied to depress the skin in a manner forming a ring of depressed body tissue in surrounding relationship to the incision, causing the incision to bulge and the sides of the incision to open, whereby body fluid is forced out through the opening of the incision. A stimulator member is mounted to an end of a lancet-carrying housing for applying the force. The stimulator member can be movable relative to the housing, and can be either heated or vibrated to promote movement of the body fluid.

  • Publication number: 20110001323
    Abstract: An energy harvester capable of providing motion from fluid flow, which comprises at least one Magnus cylinder driven to rotate by the movement of the fluid past a fin device. This causes the Magnus cylinder to rotate, and further interactions between the rotating Magnus cylinder and the moving fluid generate a Magnus lifting force. A channel or system may be also provided to direct the fluid flow to the Magnus cylinder. This rotating Magnus cylinder configuration is integrated into a mechanical device that is designed to transfer the Magnus lifting forces into a rotary mechanical motion to drive an electric generator. The device can be utilized in either air or hydraulic environments. A modification of the energy harvester can also be configured to utilize the generated electricity to produce hydrogen for use in fuel cells, or for combustion.

  • Publication number: 20100331731
    Abstract: 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, drive mechanism, kneading or vibration mechanism, optional suction system, 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 for receiving the sample and providing testing or analysis indication or readout for the user. In one configuration, the lancing needle may be withdrawn very slightly from the point of maximum penetration to create an opening in which blood can pool before being suctioned through to device.

  • Patent number: 7828749
    Abstract: 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.

  • Publication number: 20100222704
    Abstract: 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.

  • Publication number: 20100045046
    Abstract: A reaction energy harvester capable of providing motion from fluid flow, including a foil/wing capable of being rotated to present the foil/wing so that the maximum lift is generated. The lift is created by the fluid flowing past the foil/wing. A channel or system may be provided to direct the fluid flow to the foil/wing. The rotating foil/wing 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 generated to produce hydrogen for use in fuel cells or for combustion.

  • Patent number: 7635517
    Abstract: The invention includes fabrics that have been dyed or finished with a dye that contains a conductive mixture of conductive organic materials, inorganic materials, metals, metal oxides, carbon and carbon nanotubes or combinations or mixtures thereof. The dye is used to finish a fabric such that it is conductive. These fabrics are useful in shielding law enforcement personnel from energy weapons discharge and in providing an electrostatic medium for personnel that work with static sensitive products. The fabrics, when appropriately grounded, dissipate the emitted charge and transmit it to ground. Additionally, the apparel has high wear resistance and is both thermally and electrically conductive yet is comfortable to wear.

  • Patent number: 7513437
    Abstract: 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.
