A feedthrough terminal assembly for active implantable medical devices includes a structural wire bond pad for a convenient attachment of wires from either the circuitry inside the implantable medical device or wires external to the device. Direct attachment of wire bond pads to terminal pins enables thermal or ultrasonic bonding of lead wires, while shielding the capacitor or other delicate components from the forces applied to the assembly during attachment of the wires.

A method and apparatus for data transmission between an electromedical implant having a first transmitter/receiver unit, such as a cardiological implant, and an associated external apparatus having a second transmitter/receiver unit. Data transmission begins with a triggering signal which is sent by the first transmitter/receiver unit in normal operation in predeterminable first intervals. Reception readiness of the first transmitter/receiver unit is maintained after emission of the triggering signal for a second time interval which is shorter than the first time interval.

An electromagnetic interference filter terminal assembly for active implantable medical devices includes a structural pad in the form of a substrate or attached wire bond pad, for convenient attachment of wires from the circuitry inside the implantable medical device to the capacitor structure via thermal or ultrasonic bonding, soldering or the like while shielding the capacitor from forces applied to the assembly during attachment of the wires.

This invention relates to a polymeric ballistic material comprising a high molecular weight, high density polyethylene (HMW-HDPE) and/or composite, and to articles made from this ballistic material suitable for stopping projectiles. The articles may include backstops for firing ranges and home use, armor for vehicles, personnel, and aircraft, training targets, protection for temporary or mobile military and/or police installations, buildings, bunkers, pipelines or any “critical” need equipment that might require protection from ballistic impact, and the like.

A flexible armor system adaptable to a garment suitable for extremity protection uses planar, polygon-shaped solid elements made of ceramic cores wrapped in high strength fabric and arranged with rotable edge and intersection protection as a flexible mosaic array which is bonded between an elastic strike side spall cover and a high tensile strength flexible backer layer, further supported by a substantial fiber pack. A progressive mode of localized system failure during a ballistic strike includes: a projectile penetrating the spall cover, fracturing the ceramic core of a wrapped SE while being partially deformed; the deformed projectile accelerating the fractured but still wrapped solid element before it so as to free the solid element from the array and drive it through the flexible backer as a combined mass at a reduced velocity into the fiber pack.

A fastener driving apparatus includes a power source, a control circuit, a motor, a first cylinder, a first piston, a linear motion converter, a second cylinder, a second piston, an anvil, a retention element retaining a component of the apparatus, and at least one sensor. During a compression stroke, the first piston compresses gas in a first cylinder to a predetermined pressure. Compressed gas is communicated to the second cylinder and the retention force of the retention element is overcome, to release the retained component of the apparatus, thereby causing the second piston to move linearly and enabling the anvil to drive the fastener into the workpiece. During a return stroke of the first piston, a vacuum created in the first cylinder is communicated to the second cylinder, causing the second piston and the anvil to retract to their initial positions.

A tank agitator connects to a low head feed and causes agitation by discharging through a port that might rotate, oscillate, or otherwise issue a pulsing stream. This agitator has a housing with a turbine plenum and an exhaust plenum. A turbine in the turbine plenum spins by the flowthrough of the feedwater and exhausts to the exhaust plenum. A hollow drive shaft is spun by the turbine and extends through the exhaust plenum and to terminate outside the housing. It has an aperture that allows water in the exhaust plenum to flow into its lumen. A nozzle caps the shaft and is bent such that the discharge issuing therefrom sweeps in circles with the spinning of the drive shaft. A variant form of the agitator includes a drive train that incorporates a drag link to convert the spinning input of the turbine into an oscillating output in the drive shaft. In another variant form, the discharge is pulsed. To do this, the exhaust plenum lies between an opening to the turbine plenum and a port in the housing wall to the outside. A blocker door is coupled to and driven by the spinning turbine to cycle between uncovering and covering one of the exhaust opening and the discharge port. Given the foregoing, the discharge stream issuing from the discharge port will pulse between alternating phases of flow and quiescence.

An energy dissipative element (24) protects hard disk drives (22, 72, 92) from shocks and vibrations. A closed elastic envelope (48) houses a body of open cell foam (54), a volume of viscous liquid (56), and a compressible gas (64). Under compression or expansion of the foam (54), viscous liquid (56) flows through cell orifices and thereby dissipates energy resulting from external force applied against the elastic wall (48). The energy dissipative elements (24) are applied between a disk drive housing (22) and an outer case (26) to create a ruggedized portable disk drive module (20).
