The present disclosure generally relates to an insulating device, for example a cooler, and a latch and latching system for securing a lid of the insulating device in a closed position. More specifically, the insulating device includes a chest coupled to a lid, and a ledge extending from the chest. A slot is formed in the ledge and for each slot, a pair of protrusions extend from a bottom surface of the ledge on other side of the slot. The protrusions are received by corresponding recesses formed in the latch. Thus, when the latch is in the engaged position, the protrusions are physically securely engaged in the recesses by virtue of the latch being in a tensioned configuration.

The present disclosure describes a system and method to classify optical coherence tomography (OCT) images. The present system can classify OCT images without first segmenting the retina tissue. The system can generate one or more profiles from vertical transects through the OCT images. The system can identify image statistics based on the one or more profiles. The system's classifier can then classify the OCT images based on the identified image statistics.

The present disclosure describes a system and method to segment optical coherence tomography (OCT) images. The present system uses a hybrid method that employs both Bayesian level sets (BLS) and graph-based segmentation algorithms. The system first identifies retinal tissue within an OCT image using the BLS algorithms. The identified retinal tissue is then further segmented using the graph-based segmentation algorithms.

This disclosure provides systems, methods, and apparatus for analyzing a video are disclosed. An input video signal can be received and a quality metric associated with the input video signal can be determined. A parameter to be used in a first object tracking process can be selected, based in part on the quality metric associated with the input video signal. A background model can be extracted from the input video signal based on an online median estimate of the intensity values of the pixels in the image frames. The online median estimate can be calculated using a quantile function.

A rotating aperture system includes a low-pressure vacuum pumping stage with apertures for passage of a deuterium beam. A stator assembly includes holes for passage of the beam. The rotor assembly includes a shaft connected to a deuterium gas cell or a crossflow venturi that has a single aperture on each side that together align with holes every rotation. The rotating apertures are synchronized with the firing of the deuterium beam such that the beam fires through a clear aperture and passes into the Xe gas beam stop. Portions of the rotor are lapped into the stator to improve the sealing surfaces, to prevent rapid escape of the deuterium gas from the gas cell.

A water sampling apparatus is disclosed having a water inlet and a water collecting scoop. A pump, in fluid communication with the water inlet, draws a water sample from a body of water through the water inlet. A plurality of testing units, in fluid communication with the pump and the water inlet, determine characteristics of a the water sample. The plurality of testing units are contained within an instrument module. A plurality of electrical components, in communication at least with some of the plurality of testing units, generates data signals concerning the characteristics of the water sample. The plurality of electrical components are contained within a computer module. A computer, in communication at least with some of the plurality of electrical components, collects the data signals generated by the plurality of electrical components and provides the data signals both to a local database and also by satellite transmission to a remote central data base. An automated anti-bio fouling system and an automatic sensor calibration system are also discussed. A water outlet, in fluid communication with the plurality of testing units, returns the water sample to the body of water.

A shield for blocking radiation emanating from an antenna within a predetermined radial spectrum. The inventive device includes an arcuate shield positionable along an exterior of an antenna. A securing mechanism is coupled to the shield for securing a position thereof relative to the antenna such that radiation is excluded from a predetermined radial spectrum to protect a head of a user from the radiation.

A support and maneuvering device includes an elongated flexible inflatable enclosure having a fixed end and a movable end. The movable end is collapsible toward the fixed end to a contracted position when the enclosure is in a noninflated condition. Upon inflation, the movable end is movable away from the fixed end to an extended position. The movable end includes means for mounting an article such as a solar reflector thereon. The device also includes a plurality of position controlling means disposed about the movable end to effect adjusting movement of portions thereof by predetermined amounts and for controlling an angle at which the article disposed at the movable end is oriented. The plurality of position controlling means limits a suitable number degrees of freedom of the movable end for transmitting a steering motion thereto and for controlling the position thereof.

The invention is a process for producing improved electrical-junction devices. The invention is applicable, for example, to a process in which a light-sensitive electrical-junction device is produced by (1) providing a body of crystalline semiconductor material having a doped surface layer, (2) irradiating the layer with at least one laser pulse to effect melting of the layer, (3) permitting recrystallization of the melted layer, and (4) providing the resulting body with electrical contacts. In accordance with the invention, the fill-factor and open-circuit-voltage parameters of the device are increased by conducting the irradiation with the substrate as a whole at a selected elevated temperature, the temperature being selected to effect a reduction in the rate of the recrystallization but insufficient to effect substantial migration of impurities within the body. In the case of doped silicon substrates, the substrate may be heated to a temperature in the range of from about 200.degree. C. to 500.degree. C.

Coupling mechanism (11) for engaging and lifting a load (12) has a housing (19) with a guide passage (18) for receiving a knob (13) which is secured to the load (12) through a neck (15) of smaller diameter. A hollow ball (23) in the housing (19) has an opening (27) which receives the knob (13) and the ball (23) is then turned to displace the opening (27) from the housing passage (18) and to cause the neck (15) to enter a slot (29) in the ball (23) thereby securing the load (12) to the coupling mechanism (11) as elements (49) of the housing (19) block travel of the neck (15) back into the opening (27) when the ball (23) is turned to the load holding orientation. As engagement of the load (12) and locking of the coupling mechanism are accomplished simultaneously by the same ball (23) motion, operation is simplified and reliability is greatly increased. The ball (23) is preferably turned by a motor (32) through worm gearing (36) and the coupling mechanism (11) may be controlled from a remote location. Among other uses, the coupling mechanism (11) is adaptable to the handling of spent nuclear reactor fuel elements (12).
