  • Patent number: 7073246
    Abstract: A method of making a biosensor is provided. The biosensor includes an electrically conductive material on a base and electrode patterns formed on the base, the patterns having different feature sizes. The conductive material is partially removed from the base using broad field laser ablation so that less than 90% of the conductive material remains on the base and that the electrode pattern has an edge extending between two points. A standard deviation of the edge from a line extending between two points is less than about 6 ?m.

  • Patent number: 6990698
    Abstract: An adjustable articulated bed with separate adjustable leg and head/back assemblies which support an articulating mattress. The invention is manufactured in three pieces specifically designed for economical shipping directly to consumers via United Parcel, FedEx or US Postal, and is easily assembled without tools. The appearance of the bed is similar to that of a standard bed box spring or platform foundation and may be assembled and placed on a traditional metal frame, headboard, or footboard with side rails. Optional adjustable height legs are threadably attachable into support brackets connected to the bottom of each assembly to adjust the overall height of the bed.

  • Patent number: 6372069
    Abstract: A method for utilizing discarded tires is disclosed which creates strong, durable, posts, beams, mats, blocks or other structures. Used tires are cut and flattened and the sidewalls are removed. The tread sections of the tires are cleaned. Vulcanizing compound is then applied to adjacent inner surfaces of the tread sections to form a flat essential building element. These building elements may be vulcanized together in alternating horizontal and perpendicular layers to form flat blocks, mats, noise or safety barriers, or other structures. The essential building elements are flat and form structures which have flat upper and lower surfaces and a rectangular cross-section. Beams may be formed by securing a number of the essential building elements together to form structures that are approximately 8 feet high and have a rectangular cross-section.

  • Patent number: 6357124
    Abstract: The present disclosure relates to a jig saw including a base structure, and a housing pivotally moveable relative to the base structure about a first axis that extends longitudinally along the base structure. A motor is positioned within the housing. The motor reciprocates a blade in an up and down motion. A connecting member extends between the housing and the base structure. The saw also includes a first wedge that cooperates with the connecting member to clamp the housing relative to the base structure. The first wedge is moveable to a first position in which the connecting member is caused to compress the housing and the base structure together such that pivotal movement between the housing and the base structure is inhibited. The first wedge is also moveable to a second position in which the housing can be manually pivoted relative to the base.

  • Patent number: 6230411
    Abstract: The present disclosure relates to a jigsaw including a base, a housing pivotally movable relative to the base about a first axis that extends longitudinally along the base, and a motor positioned within the housing. The jigsaw also includes a blade coupled to the motor by a drive mechanism adapted for reciprocating the blade in an up-and-down motion. The blade is laterally supported by a blade guide connected to the base that is pivotally movable about the first axis. When the housing is pivoted relative to the base about the first axis, the blade guide also pivots about the first axis to inhibit binding between the blade and the blade guide.

  • Patent number: 6178646
    Abstract: The present disclosure relates to a jig saw blade clamp including a first clamp member defining a main slot. A second clamp member is positioned within the main slot. The first clamp member is moveable relative to the first clamp member between a first position in which the first and second clamp members are adapted to clamp a blade, and a second position in which the blade can be inserted between the first and second clamp members. A collar is pivotally moveable in first and second opposite directions relative to the first and second clamp members. The collar includes a cam portion that moves the second clamp member toward the first position when the collar is pivoted in the first direction, and also moves the second clamp member toward the second position when the collar is pivoted in the second direction.

  • Patent number: 5375636
    Abstract: A pocket joint cutter system for forming a pocket cut and fastener bore into a workpiece. The pocket cut and fastener bore receives a fastener such as a self-tapping screw which passes through the bore and into a second workpiece for forming a Joint between the two workpieces. The head of the fastener is held within the pocket cut in order to secure the joint. In one preferred form of the present invention, a workpiece system secures the workpiece in a predetermined position and forms the pocket cut and fastener bore into the workpiece. This preferred embodiment further comprises a bench-mounting system coupled to the workpiece system for securing the system to a bench. Using this embodiment of the present invention, the system can be mounted to a bench, and the workpiece can be brought to the system and held in position while the user forms the pocket cut and fastener bore.

  • Patent number: 5020518
    Abstract: A massage apparatus includes a travelling carriage having a housing enclosing a drive motor and a kneading motor. A pair of guide bars extend through the housing providing stability therefor as the carriage is traversed along an intermediate drive bar which also extends through the housing. The drive motor is coupled to the drive bar through a pinion gear. Massaging elements are mounted on a crank arm which is rocked back and forth by the kneading motor. An eccentric arm couples the kneading motor to the crank arm and provides the kneading action. A control system also mounted to the carriage reverses direction of the drive motor as ends of the drive bar are approached. A massage motor is attached to the carriage housing to apply a multidirectional vibrational waves to a user through the massage elements.
