A legless chair includes a seat, a seatback having its bottom side connected to the seat, and a flexible member backwardly extending from a rear side of the seat. When the user sitting on the seat forces his/her back against the seatback to tilt the legless chair backwards, the flexible member is bendable to impart a damping force against the backwardly tilting motion of the legless chair so as to prevent the backward falling of the legless chair.

The invention provides a unitary cordless dental drive apparatus in a first embodiment having a handpiece with a cantilever arm 18 extending outward and positioned to allow a dental nose cone 26 to be connected. An activating switch 20 is located at the free end of the cantilever arm 18 in a position that is convenient for manipulation by a user. In a second embodiment, a contactor 22 is mounted below the cantilever arm 18′ to contact the nose cone 26′ when pressed. In a third embodiment, a standard dental office foot pedal 90 is connected to a wireless transmitter 80 for sending a signal to a receiver 92 located within the handpiece 70 for activating the handpiece 70.

An advanced PCI express board assembly is mountable in a PCI express slot. The assembly includes a main board that is attached to an adapter board by a connector section that includes mechanical and electrical connectors. When the main board is attached to the adapter board, the plane defined by the main board is parallel to, and laterally offset from, the plane defined by the adapter board. The adapter board is connectable to a female PCI express connector in the PCI slot. When the adapter board is connected to the female PCI express connector, the main board plane is perpendicular to the motherboard and is laterally offset from the PCI express slot. More and larger components can be placed on the main board while the assembly remains within the reserved PCI express space.

PCI Express Cluster dedicated for system expansion through installation of up to four high-performance PCI Express boards (example: graphics processing units—GPU).Cluster includes a special chassis and a backplane. Add-in PCI Express boards are plugged into PCI Express connectors that are located on both sides of the backplane (two on the top side and two on the bottom side); said boards are specially oriented, relative to each other, thereby ensuring that all component sides of said four PCI Express boards will be directed outwards.This type of PCI Express board placement allows the cooling fans, located on the component side of each PCI Express board, to intake cooling air at ambient temperature, and to eliminate the possibility of airflow obstruction or intake of air that has already been heated by nearby boards.PCI Express Cluster can be connected to host computer in the first implementation or operate independently as a stand-alone device in the second implementation.
摘要:
The present invention relates to a method and system for detecting biologically relevant structures in a hierarchical fashion, beginning at a low-resolution and proceeding to higher levels of resolution. The present invention also provides probabilistic pairwise Markov models (PPMMs) to classify these relevant structures. The invention is directed to a novel classification approach which weighs the importance of these structures. The present invention also provides a fast, efficient computer-aided detection/diagnosis (CAD) system capable of rapidly processing medical images (i.e. high throughput). The computer-aided detection/diagnosis (CAD) system of the present invention allows for rapid analysis of medical images the improving the ability to effectively detect, diagnose, and treat certain diseases.
摘要:
A method and system for protection against natural temperature-dependent dangerous phenomena connected with huge streams mainly water, mud, locust. The method allows weakening these streams and allows protecting against these dangers at least at of the first two stages of development of said phenomena: forming these masses and their moving, as far as possible. The method allows protecting ecology and increasing CO2 absorption. The system allows also transporting the electrical energy that is received from solar radiation with help of solar cells flying in stratosphere to ground-based reception stations.

An optical assembly includes a first transparent substrate having first and second surfaces, a second transparent substrate having substantially parallel third and fourth surfaces, a reflective portion on the second transparent substrate, a plurality of filters between the first substrate and the reflective portion, the plurality of filters filtering light beams incident thereon, the plurality of filters and the reflective portion forming a bounce cavity within the second transparent substrate, a collimating lens for collimating light beams to be input to the bounce cavity, a tilt mechanism for introducing tilt to light beams input to the bounce cavity; an input port receiving light beams and an output port transmitting light beams. The tilt mechanism may be between the first and second substrate.

摘要:
Integrated multiple optical elements may be formed by bonding substrates containing such optical elements together or by providing optical elements on either side of the wafer substrate. The wafer is subsequently diced to obtain the individual units themselves. The optical elements may be formed lithographically, directly, or using a lithographically generated master to emboss the elements. Alignment features facilitate the efficient production of such integrated multiple optical elements, as well as post creation processing thereof on the wafer level.
