A luminescence shock avoidance algorithm selectively limits the brightness level of a display device when the display device is activated in a dark environment to prevent the temporary vision impairment that can occur when a display device is activated in a dark environment. The algorithm receives the state of the display (e.g. on or in standby mode), and can optionally receive an ambient lighting value from an ambient light sensor and a user-selectable manual brightness adjustment setting to determine whether luminescence shock avoidance should even be triggered, and if it is triggered, how much should the brightness level of the display be limited.

This invention provides a system and method for hand-eye calibration of a vision system using an object under manufacture having at least one feature. The feature can be a linear feature and the object moves in at least one degree of freedom in translation or rotation on a motion stage. The system further comprises at least a first vision system camera and vision processor. The first vision system camera is arranged to acquire an image of the first linear feature on the object under manufacture and to track motion of the first linear feature in response to moving of the motion stage in at least one degree of translation. The first linear feature is identified in at least two different positions along a plane. The system computes a mapping between pixel positions in a pixel coordinate system of the first camera and physical positions in a motion coordinate system based upon locations of the at least two positions.

The invention relates to an urban railway traffic continuous basin type beam. A beam body of the continuous basin type beam is a passage which has the basin-shaped cross section and is formed by connecting a support bottom plate, upper web plates and wing edge plates, the upper web plates are arranged at both sides of the support bottom plate, the wing edge plates are arranged at the tops of the upper web plates, at least two pairs of rail carrying tables are arranged on the support bottom plate, a power supply device, power supply cable support bodies and communication signal cable grooves are fixedly connected in the length direction of the beam body, the span of the beam body is 40m to 80m, the support bottom plate of the beam body at the side fulcrum region section and the middle spanflat and straight section is in a single layer, the rest support bottom plate of the beam body is in a closed opening box shape, in addition, the lower surface of the single-layer support bottom plate of the side fulcrum region section and the middle span flat and straight section is in smooth transition connection with the bottom surface of the box shape. The beam is arranged at the crossed transition line region section or a place required to span a large node, the urban railway traffic continuous basin type beam belongs to a bridge structural form integrating the thin-wall opening U-shapedbeam and the closed opening box-shaped beam into a whole, the problems that the ordinary railway traffic U-shaped beam cannot span large node and cannot be applied to the crossed wire transition region section are solved, and the application range of the U-shaped beam is enlarged.

The disclosure relates to a device for establishing an anatomical reference point of an intervertebral disc for the attachment of at least one instrument Intended for the implantation, through a posterior or posterolateral approach, of a disc prosthesis or osteosynthesis cage as a replacement for the intervertebral disc. The device includes at least two means for bone anchorage each intended to be attached to a vertebra adjacent to the disc, a coupling element for the instrument and elements for adjusting the position of the coupling element relative to the position of the disc.

Regarding a tractor which is a passenger work vehicle includes: a drive operating unit; and a hood arranged in front of the drive operating unit. In the tractor, the height of the hood from the ground is reduced from the rear end to the front end of the hood constituted of an upper surface, an upper left surface and an upper right surface, and is reduced from the center of the hood in the right-left direction to the right and the left of the hood. When viewed from a plane, the left-side ridge line on the upper left surface and the right-side ridge line on the upper right surface of the hood converge at the center of the front end of the hood.

A front face attachment for a fireplace allows a single fireplace construction to be converted from a first arrangement having front facing top outlet and bottom inlet with covering louver panels for air flow around the combustion chamber to a second arrangement in which there are no front facing outlets and the top and bottom outlets are behind front cover flanges for receiving cladding materials.

The visor joins to the roof of a motor vehicle to deflect heavy precipitation, such as a downpour, from a windshield. The visor is a permanent motorized device with a hollow planar cover. The cover contains a means to extend and retract the visor from the cover and over the windshield. The extension and retraction means is a spring balanced motorized cable and pulley system. The cable attaches to the rear of the visor and the visor has rollers in tracks for extending and retracting from the cover. A driver presses the switch to extend the visor as the motor unwinds the cable and the springs relax. When a downpour passes, the driver presses the switch to retract the visor as the motorized system reverses. The visor reduces vision impairment of drivers caused by precipitation.

An apparatus and method for preventing ocular surface abnormalities. This apparatus includes a frame containing at least one lens and at least one seal. The frame, lens, and seal provide an area about the eyes of a user that is at least partially enclosed from a surrounding environment when worn. Humidity and temperature are increased in the area about the eyes of the user to provide a microenvironment in the area about the eyes of the user. The microenvironment is capable of reducing or preventing ocular surface abnormalities, alleviating ocular discomfort, and improving ocular health. The seal may be removable and may attach to prescription eyeglasses, sunglasses, and so on. The seal may also contain a filter, such as a HEPA filter.

An apparatus and method for detecting and correcting improper head neck and back movement during sports. The apparatus may include a non-reflective shield positioned near at least one eye of a user. The shield may be oriented at an angle parallel to a users' vision while in the open position, and the shield may be oriented at an angel perpendicular to a users' vision while in the closed position. Additionally, a swing arm or movement response unit may move the position of the shield from open to closed in response to the movement of a user.
