摘要:
A wind turbine shaft includes tubes that are centered on a longitudinal axis, coupled to rotate together about the axis, and movable telescopically along the axis between a retracted condition and an extended condition. A mounting structure is configured to mount wind turbine vanes on the tubular structure when the tubes are in the extended condition. A generator has a pair of parts including a rotor and a stator, and is configured for coupling with the tubular structure for one of the parts to rotate about the axis with the tubular structure while the other part is stationary.

A wind turbine is disclosed. The wind turbine includes a shaft rotatable about an axis, a plurality of hubs fixedly attached to the shaft, and a plurality of vanes. The vanes are releasably engaged with each of the plurality of hubs. The vanes disengage from the hubs once the shaft rotates about the axis at a cut-out speed of the wind turbine. In another embodiment, the vanes are releasably engaged with the shaft.

An object tracking system includes a sensor grid having a plurality of sensor clusters configured to sense the presence of a magnetic field of an object. Each sensor cluster includes three or more single-axis magnetic sensors. The sensors in a cluster may be arranged with their axes parallel to one another. The sensor grid may account for ambient magnetic noise by measuring the magnetic field in a zone a distance away from the object to update the ambient magnetic field noise measurement. The sensor grid or a portion thereof may include a plurality of sensors printed on a common sheet. The sensor grid may comprise one or more sheets overlapped or interconnected. The system may track an object and determine up to three degrees of positioning and three degrees of orientation by using a geometric solution of the intercepts of magnetic field strengths obtained from information collected by the magnetic sensors.

A quarter wave coaxial cavity resonator for producing corona discharge plasma from is presented. The quarter wave coaxial cavity resonator has a folded cavity made of opposing concentric cavity members that are nested together to form a continuous cavity ending in a aperture. A center conductor with a tip is positioned in the cavity. The folded cavity advantageously permits the coaxial cavity resonator to resonate at a lower operating frequency than an unfolded quarter wave coaxial cavity resonator of the same length. Embodiments of the quarter wave coaxial cavity resonator use narrower apertures to reduce radiative losses, and include center conductors that are reactive load elements, such as helical coils. When a radio frequency (RF) oscillation is produced in the quarter wave coaxial cavity resonator, corona discharge plasma is formed at the tip of the center conductor. The corona discharge plasma can be used to ignite combustible materials in combustion chambers of combustion engines.

In one embodiment, a processor can operate in multiple modes, including a direct execution mode and an emulation execution mode. More specifically, the processor may operate in a partial emulation model in which source instruction set architecture (ISA) instructions are directly handled in the direct execution mode and translated code generated by an emulation engine is handled in the emulation execution mode. Embodiments may also provide for efficient transitions between the modes using information that can be stored in one or more storages of the processor and elsewhere in a system. Other embodiments are described and claimed.
摘要:
A non-invasive method for determining and characterizing the presence of damage or abnormalities resulting from or concomitant with systemic hypertension in subject. This method is comprised of the acquisition of ocular image(s) and subsequent evaluation, classification and/or interpretation of these image(s). The ocular image(s) may be acquired by photography. Evaluation, classification, and/or interpretation may be automated or involve the active participation of a human. The ocular images may be classified into either a normal or clinical group or compared to an algorithm of hypertensive symptoms. The ocular images may, additionally, be processed and have the pertinent characteristics extracted to make the classification more exact.
摘要:
A glider including a center section configured to receive and support an operator thereon, and a pair of air-foil shaped wings extending generally outwardly from the center section. The glider is configured such that when the glider supports the operator thereon the glider is glidable down an incline in the ground effect zone of the incline, and is configured such that the glider cannot sustainably glide above the ground effect zone.
摘要:
A method of monitoring a subject for medical conditions includes causing light to impinge on at least one eye of the subject, directing reflected light from such light beam to photosensors, converting the received reflected light to corresponding electrical signals which are delivered to a processor. Processing the signals by effecting a comparison between stored information regarding the medical condition and the data provided by the monitoring to determine if an undesired medical condition exists and, if so, communicating such result. The cycle is repeated at predetermined intervals which may be short or prolonged. The stored information may be information relating to the specific subject or general information regarding normal and abnormal conditions of the eye representative of toxicity. The eyes may be monitored sequentially or simultaneously. Related apparatus is provided.
摘要:
A panel, preferably a ceiling panel, for an arc resistant cabinet defines at least one flap dimensioned and configured to bend outward in response to excessive pressure within the cabinet. The flap is bent into a position wherein it will direct high temperature, expanding gases exiting the cabinet away from areas where personnel are likely to be located. The panel also includes a frame below the flap, thereby permitting the entire panel, including the flap, to support the weight of people working on top of the cabinet.
