  • Patent number: 9703899
    Abstract: A product synthesizer has a core CPU, power distribution, and a plurality of selectable interfaces, each interface having an associated schematic symbol, PCB symbol, mechanical model, power dissipation, and power requirement. A set of constraints identifies performance metrics including low power, high performance, battery or mains power, battery life, and other constraints. The product synthesizer receives as inputs the interfaces and constraints, and generates as outputs a schematic diagram, a bill of materials, a routed printed circuit board, and a solid model of an enclosure, all of which satisfy the constraints and include the identified interfaces.

  • Patent number: 6406175
    Abstract: A device for preparing and injecting a polymeric bone cement under sterile, isobaric and isovolumic conditions includes a cylindrical vessel holding a volume of polymeric powder and a disk agitator mounted on a shaft passing through an aperture in a proximal end wall of the vessel and extending beyond the agitator though a delivery port in an opposite wall of the vessel. A piston can be selectively coupled to the disk in order to inject the contents of the vessel through the outlet port. The device can be packaged in a sterilized, evacuated envelope. The cement is ejected by breaking off a distal, tubular section of the shaft and mounting the broken off section over an external bushing surrounding the outlet port and moving the piston toward the outlet port to expel the contents of vessel.

  • Patent number: 5975366
    Abstract: A device for efficient storage, measuring, and dispensing of several powdered and/or particulate materials holds these materials in a side-by-side array of compartments. Each compartment has a storage chamber and a measuring chamber. Dispensing is prompted by gravity and agitation, for orderly flow of each material through its two chambers as their drain gates are selectively opened. Simultaneously with the opening of the gate under either chamber, a dc eccentric motor acts on that chamber to break up any clumps of material that might impede free flow. Each of the two chambers has its own motor. The storage chamber array is structurally separate from the measuring chamber array, so that the two chambers can vibrate separately, further improving free flow.

  • Patent number: 5725131
    Abstract: A valve and dispensing assembly for dispensing powdered material from a container includes a flexible tube intended to be collapsed to actuate a valve which permits the tube to selectively open for dispensing the material through the tube. The assembly includes a flexible tube apparatus including a body attachable to the container and a valve releasably received within the tube and normally closing it off. Collapse of the tube causes it to move relatively of the valve to unseat it and open the tube for material discharge. The assembly also includes a declumper secured to the tube for movement therewith during collapse of the tube. The valve closes off the tube when in its uncollapsed condition while the tube and declumper move relatively of the valve during collapse to open the tube. A portion of the declumper is bifurcated and has serrated opposed edges which can engage the head of the valve during the tube collapse to assist in breaking up clumps which may have formed in the material.

    Abstract: Apparatus which controllably meters dry powder from a powder supply chamber falling through a vertically disposed axial passageway interconnecting the supply chamber with a mixing chamber therebelow for forming an air-powder mixture therein for transport to a desired site. A tapered plug member is bonded to a bimorph bender comprising a piezoelectric element bonded to each face of a thin, flat, cantilevered metallic beam which is deflectable by a dc bias or driving voltage applied to the bender to cause the tapered plug to penetrate or move within the passageway, thus varying width of annular gap formed between the plug and passageway, and hence, amount of powder capable of falling therethrough. An oscillating voltage may be impressed upon the piezoelectric elements to cause the deflected beam to additionally be vibratorily displaced in accordance with the frequency of vibrations of the impressed oscillating source.
