  • Publication number: 20240091093
    Abstract: The subject invention pertains to systems and methods to improve the condition of an eye and to either treat or lower the risk of diseases such as glaucoma. Systems and methods are provided for increasing compliance, improving circulation and fluid flow, or promoting tissue cell metabolism by warm compress, and/or irradiation at single or multiple wavelengths (e.g., between 780 to 950 nm or between 550 to 700 nm), and/or application of static and/or dynamic pressure to the eye. Embodiments provide a wearable head set with pressure controlled goggles, controlled irradiation sources, and temperature-controlled heat sources or pads exposed to or in contact with the eye or surrounding region to warm up the tissues of the eye and promote the vasodilation of the blood vessels at the eye as well as circulation within the blood system connected to the Schlemm's canal or other regions in or around the eye.

  • Patent number: 11302185
    Abstract: The present invention relates to a traffic intersection and traffic guidance system therefor, that has an intersection region where two roads cross, and a distal crossover zone that allows vehicles that are turning to the right (on a left-hand-drive road) to crossover to the right hands side of the road at a distance from the intersection. In this way, a separate right turn phase is not required by the traffic lights at the intersection, and vehicles turning right can turn at the same time as vehicle moving straight over the intersection or turning left. The turning right lane approaching the distal crossover zone from a distal side of the distal crossover zone is located on the far left, allowing vehicles going straight to continue to move in a straight line. Lanes that guide vehicles moving straight are reconfigurable to guide vehicles to move in opposed directions at different time of the day, depending on the traffic loading, and are also reconfigurable as parking spaces.

  • Publication number: 20200211380
    Abstract: The present invention provides a traffic intersection located at an intersection of two multilane roads, each road comprising a plurality of traffic lanes spaced adjacent each other, the traffic intersection comprising an intersection region wherein the surface area of the intersecting roads overlap, a proximate region in which each road approaching the intersection defines at least one turning right lane for guiding vehicles to turn right at the intersection onto the intersecting road, at least one going straight lane for guiding vehicles to move straight through the intersection on the same road and at least one going straight receiving lane for receiving vehicles moving straight through the intersection.

  • Publication number: 20160115650
    Abstract: Anti-bottleneck mode traffic of vertical and horizontal interactive public transportation at level crossings, including four main roads crossed wherein: main roads are divided into front and rear sections, sidewalk between two sections and has pedestrian signal lights, the road front section has front section right-turn lane, front section turnback lane and front section through lane, between the front section and the sidewalk is front section signal light group. The rear section has rear section right-turn lane and rear section through lane, the rear section has rear section turnback lane and rear section through lane, the rear section has a rear section signal light group, and two sides of the sidewalk have a turning basin. Combinations produced by turnback alternately shielded by vertical and horizontal men and vehicles. Non-obstruction road sections of bus stops are pointed out. There are no direct intersection conflicts keeping anti-bottleneck mode at all times.

  • Publication number: 20160063859
    Abstract: A traffic intersection is configured to allow for the splitting of turning left lane from the other lanes at a region distal from the intersection region at a crossover zone to reduce bottlenecks at the intersection region itself and smoothes the flow of traffic. Also provided are a traffic guidance system, a traffic signaling arrangement, a pedestrian crossing, a pedestrian crossing guidance system, a directional indicator arrangement, a method of marking a traffic intersection and a method of determining a marking protocol for use at or with the traffic intersection.

  • Publication number: 20150043969
    Abstract: An overpass, including: a main road, an auxiliary road, a turntable, a cross-shaped viaduct, a sidewalk, an elevated bicycle lane, an elevated bicycle parking layer, and a first lower level floor. The main road includes: a first lower level main connecting lane. The auxiliary road includes: a first lower level auxiliary connecting lane. The turntable includes: a plurality of bus stops, taxi docking stations, and outer pedestrian ladders. The cross-shaped viaduct includes: a dual-line bridge and a single-line bridge. The first lower level floor includes a first lower level parking lot. The main road and the auxiliary road cross intersect at the turntable. The cross-shaped viaduct crosses above the turntable and is connected to the main road and the auxiliary road. The dual-line bridge is connected to the main road and the single-line bridge is connected to the auxiliary road.
