An expandable venous valve having a support structure that configured to enlarge the area adjacent to the valve structure such that the flow patterns of retrograde flow are modified in a way that facilitates the flushing of the pockets at the base of the valve area to prevent stagnation of bodily fluid, which in the venous system, can lead to thrombus formation. The enlarged pocket areas can be created by forming an artificial sinus adjacent the valve structure in an unsupported section of vessel wall between two support frame section or the support frame can comprise an expanded-diameter intermediate or proximal section that forms an artificial sinus adjacent the valve structure. In another group of embodiments, the attachment pathway between opposing leaflets and the support frame and / or vessel wall comprises a proximal portion that places the leaflets in extended contact with one another and a distal portion forms a large angle with respect to the adjacent walls such that a large pocket is created at the base of the leaflets. In one embodiment, the attachment pathway extends distally along a pair of substantially parallel longitudinal attachment struts to create an extended leaflet contact area, then angles circumferentially and distally from the former along distal attachment struts to define the bottom edge of the leaflets.

The non-contact wireless communication apparatus includes a non-contact wireless communication antenna, a resonance capacitor, connected in parallel with the non-contact wireless communication antenna, for obtaining a predetermined resonance frequency with the non-contact wireless communication antenna, a resonance frequency adjustment unit for changing a resonance capacitance of the resonance capacitor to adjust the resonance frequency, a capacitance change amount control unit for controlling a change in resonance capacitance of the resonance capacitor in the resonance frequency adjustment unit, a resonance frequency shift unit for shifting the resonance frequency of the non-contact wireless communication antenna, and on / off control unit for performing on / off control of the resonance frequency shift unit in accordance with the amount of change in resonance capacitance of the resonance capacitor by the capacitance variation control unit.

A seeding apparatus having a distribution manifold with selectively openable outlet ports thereon, to permit or stop delivery of seed or fertilizer to soil A meter device, responsive to both the number of selected open ports and the speed of the apparatus over the ground, is provided to regulate supply of seed / fertilizer to a distribution manifold. The distribution manifold has a plurality of outlet ports spaced about a periphery of such manifold, each outlet port having a valve to allow opening and closing of individual outlet ports. Soil engaging members on such apparatus are individually raisable from an lowered operative position to a raised inoperative position, and when moved to such inoperative position, valve associated with an outlet port for providing seed and / or fertilizer to such soil engaging member is closed to prevent supply to the associated soil engaging member.

Illumination sources are turned ON and turned OFF in response to detected levels of illumination in an ambient environment reaching respective thresholds, which may be user set. The detection of these turn ON and turn OFF events is verified, for instance against expected events or conditions for the particular location, date and / or time. An alert or log entry may be generated if a detected event or condition appears to be invalid. For instance, if an amount of illumination in the environment is different than predicted by a threshold amount or if a time that the event occurs or is detected is different than expected or predicted by more than a threshold amount. A level of illumination may be decreased to some non-zero level after a specified time after turn ON, and increased at some specified time before turnOFF. Use of information from external sources (e.g., satellites, cell towers) may allow times to be using local time, including daylight savings if applicable.

A system for providing irrigation fluid during ablation of tissue includes a catheter, an electrode assembly, at least one thermal sensor adapted to be connected to the catheter, and a control system. The electrode assembly is adapted to be connected to an ablation generator. The thermal sensor is adapted to be operatively connected to an electronic control unit (ECU). The ECU receives as an input temperature measurement data from the thermal sensor; determines a power delivery rate value for the ablation generator responsive to the temperature measurement data; and outputs the power delivery rate value. The control system also delivers irrigation fluid to the irrigated catheter at a first flow rate in a first time period and at a second flow rate in a second time period that is temporally after the first time period. The second flow rate is at least half of the first flow rate.

System and method for developing a treatment plan for achieving a treatment goal including creating a virtual model of a dental patient's dentition; transforming the virtual model of the dentition using virtual prosthodontics to facilitate achievement of the treatment goal; transforming the virtual model of the dentition using virtual orthodontics to facilitate achievement of the treatment goal; iterating on the transforming steps until substantially achieving the treatment goal; and generating an orthodontic treatment plan and a prosthodontic treatment plan based upon the substantially achieved treatment goal

The present invention is a method and system of automatic memory management (garbage collection). An application automatically marks up objects referenced from the “extended root set”. At garbage collection, the system starts traversal from the marked-up objects. It can conduct accurate garbage collection in a non-GC language, such as C++. It provides a deterministic reclamation feature. An object and its resources are released immediately when the last reference is dropped. Application codes automatically become entirely GC-safe and interruptible. A concurrent collector can be pause-less and with predictable worst-case latency of micro-second level. Memory usage is efficient and the cost of reference counting is significantly reduced.

A semiconductor light-emitting device, and a method of manufacturing the same. The semiconductor light-emitting device includes a first electrode layer, an insulating layer, a second electrode layer, a second semiconductor layer, an active layer, and a first semiconductor layer that are sequentially stacked on a substrate, a first contact that passes through the substrate to be electrically connected to the first electrode layer, and a second contact that passes through the substrate, the first electrode layer, and the insulating layer to communicate with the second electrode layer. The first electrode layer is electrically connected to the first semiconductor layer by filling a contact hole that passes through the second electrode layer, the second semiconductor layer, and the active layer, and the insulating layer surrounds an inner circumferential surface of the contact hole to insulate the first electrode layer from the second electrode layer.

An aircraft landing assist apparatus is designed to be retrofit to existing aircraft having internal constructions that have been modified to support the apparatus. The apparatus is designed so that on rough landings of the aircraft on a ship deck, the apparatus will collapse in a controlled manner to avoid any damage to ammunition and / or fuel storage areas of the aircraft.

A method and system for collecting and distributing vehicle traffic congestion information is disclosed. The method and system optionally involves deploying probe vehicles or other data sources for collecting and transmitting detailed traffic information which describes vehicle speeds actually being experienced along the routes of interest and transmitting all this information into a central computer at a central traffic data station, where the data are processed.
