Abstract: A vaporizer includes a thermally conductive anesthetic container and a temperature sensor positioned in the container and in the liquid anesthetic. A breathing-gas delivery tube has a delivery end positioned in the liquid anesthetic at least about 5 mm beneath the top surface of the liquid anesthetic. A heater is positioned outside the container. Control circuitry is configured to receive signals from the temperature sensor and is connected to the heater in order to cause the heater to maintain the temperature of the anesthetic above a predetermined temperature. A method of vaporizing inhalation anesthetic is also provided.

Abstract: A mat assembly comprises a number of tiles adapted to be coupled together to define a substantially continuous tread surface. Each tile comprises a base 12 comprising a number of upstanding strips 14 which extend across the tile 10. Scraper strips 18 are provided in channels 16 defined between the base 12 and the upstanding strips 14, the scraper strips 18 adapted to scrape or brush material, for example, dirt, fluid and the like from the shoes of people entering a building, thereby trapping this material and preventing it from being tracked into the building.

Abstract: Intelligent hardware token processors (5) are capable of sending and receiving encrypted messages. Generic initialization with non-user-specific certificates comprising public and private keys allows a certificate authority (210) to securely communicate with the hardware token. New users enrolling with the certificate server (210) have their hardware tokens securely reprogrammed with user specific certificates.

Abstract: An adjustable jewelry assembly includes a jewelry chain or other flexible member slidably mounted to a clasp for adjusting a hanging length or opening size of the flexible member. The clasp is formed from a single piece of thin sheet material and includes a pair of walls connected together by a biasing portion. Superimposed tabs with openings extend from the walls in opposite directions. The flexible member is normally held against movement in the clasp by opposing biasing forces exerted by the edges of the openings from the biasing portion. When the walls are pressed toward each other, the flexible member may be slid through the clasp until the desired hanging length or opening size is achieved, then released to clamp the clasp and flexible member against relative movement.

Abstract: A signal interface comprises a non-reciprocal device having a first port that accepts a first electrical signal and a second port that accepts a second electrical signal. The non-reciprocal device passes the second electrical signal through the first port without a phase shift and passes the first electrical signal through the second port with a 180 degrees phase shift. An optical modulator receives an optical signal at an optical input port, a second signal at a first and a second electrical input port, the first electrical signal at a third electrical input port, and the phase-shifted first electrical signal from the non-reciprocal device at a fourth electrical input port. The optical modulator transmits the second electrical signal to the first port of the non-reciprocal device without a phase shift and modulates the first electrical signal on the optical signal and providing the modulated optical signal at an optical output port of the optical modulator.

Abstract: A modulator includes an interferometer waveguide structure formed on an electro-optical substrate, preferably a Z-cut lithium niobate or a Z-cut lithium tantalate. The substrate includes a domain inversion between a region near the first arm and a region near the second arm of the interferometer waveguide structure. In one example, two coplanar strip electrode structures, each extending near at least a portion of the first arm and the second arm, respectively, are electrically coupled to each other.

Abstract: An optical resonant modulator includes an optical ring resonator and an optical loop that is coupled to the optical ring resonator by two couplers. The optical ring resonator can have a hybrid design in which the ring resonator is formed on an electro-optically passive material and the optical loop is formed on an electro-optically active material. An amplification section can be inserted between the electro-optically passive and the electro-optically active sections. In analog applications, an optical resonator includes a Mach Zehnder interferometer section having an input and an output, with a feedback path coupling the output to the input. Applications of the optical modulator of the invention, and a method for modulating an optical signal also are disclosed.

Abstract: A watercraft with at least one onboard propulsion engine includes at least two hulls and a wing-like deck structure spanning the two hulls (a floating wing). Port and starboard skirts combine with the deck structure to form port and starboard planing channels. The deck structure includes an upwardly facing surface that slopes downwardly toward an aft end of the deck structure in order to provide aerodynamic lift. Preferably, a speed-responsive exhaust proportioning system vents exhaust at vertical steps in planing surfaces on the hulls to reduce drag, increase lift, and reduce thermal signature. One embodiment includes hinged laterally extending deck extensions that an operator can raise to reduce vessel breadth during docking, upwardly extending barriers on the deck extensions that reduce the escape of wind laterally, and hinged flap structures disposed rearwardly that enable an operator to adjust vessel trim.

Abstract: A watercraft with a propulsion engine includes at least one hull having an underside. A dual exhaust system includes a first exhaust conduit defining a first exhaust flow path leading to the underside (e.g., a step in a planing surface on the underside) and a second exhaust conduit defining a second exhaust flow path to atmosphere. One embodiment is self proportioning. In another embodiment, an onboard proportioning system varies first and second proportions of the exhaust flowing through respective ones of the first and second exhaust conduits according to exhaust back pressure. First and second valve mechanisms selectively restrict the first and second exhaust flow paths under computer or manual control according to pressure sensed by a back-pressure-sensing component in order to thereby direct the exhaust in desired proportions for enhanced operating characteristics and reduced thermal signature.

Abstract: A wheel for a piece of lawn equipment specifically designed not to produce tracks in the lawn as the lawn equipment moves over the lawn. The wheel is made of two parallel circular discs spaced apart by a center spacer. The two discs are relatively thin and thereby have minimal contact with the grass blades when rolling over the lawn. The height of the wheel and the diameter of the axle are sufficient so that glass blades on the lawn are not bent downward and extend upward between the two discs. An optional ring structure made of rubber or similar material is attached over the perimeter edge of each disc to provide greater traction and to protect the edge from damage. Located inside the wheel axle is an optional bushing or wheel bearing.

Abstract: A canting ballast twin foil (CBTF) sailing yacht constructed according to the invention includes a sailing hull, a ballast, a ballast-supporting structure, and an onboard ballast drive system. The ballast drive system moves the ballast in order to vary the counter-heeling force it produces underway. Twin foils that depend downwardly from the hull in positions fore and aft of the ballast provide leeway and steering control. An onboard main engine drive system provides power, either directly by suitable mechanical coupling or indirectly through charging of the battery/electric system, for one or more of a canting system, a leeway, and/or steering control system. The onboard main engine drive system may also power a yacht-propelling propeller.
