A retraction apparatus and method are disclosed that provide optimized access to a surgical site. In one form, a retraction frame has a retraction opening with two sets of blades operating therein. The blades are used to sequentially retract the tissue from about an incision. The sequential retraction of the blades generates only narrow gaps between the blades so that tissue and blood encroachment during the surgical procedure are minimized.

The disclosed embodiments relate to the design of a hybrid laser comprising a shared ring mirror coupled to a pair of buses by a 3 dB coupler (also referred to as a “symmetric splitter”), which is described in more detail below. Each bus is also coupled to an array of ring filters, wherein each ring filter couples an associated reflective silicon optical amplifier (RSOA) to the shared ring mirror and in doing so forms a Verniered ring pair with the shared ring mirror. The resulting system provides a comb source with redundant channels that can provide individual outputs or a shared output. This hybrid laser provides a significant improvement over existing comb-based lasers by providing redundancy for at least one laser channel.

An orthodontic bracket for receiving an arch wire of orthodontic patients having both primary teeth and permanent teeth, the orthodontic bracket including a pad sized to fit on one of the primary teeth, the pad extending a first distance generally in a longitudinal direction and a second distance generally in a lateral direction, the first distance being greater than the second distance. An eyelet can extend from the pad, the eyelet including an aperture defined through the eyelet, the aperture having a central axis oriented transverse to the lateral direction. The aperture can slidingly receive the arch wire. A method including bonding the pad of the orthodontic bracket to one of the primary teeth of the patient.

There is provided a display apparatus including a display capable of displaying a plurality of windows using a browser, a device such as a touch panel that detects a screen operation on the display performed by a user, a selection unit that selects a first window specified by the user according to a first screen operation detected by the device, and a screen region setting unit that sets the screen region of a second window with respect to the selected first window in an orientation of a browser, according to a second screen operation of the user following the first screen operation, detected by the device, the screen region of the second window corresponding to the second screen operation.

The bone coal displacement strip coal block exploration under an architecture, concentrically sets 3-5 bone coals filling lane at the center of each strip coal block, based on the buried depth, width, laminated rock structure and protective degree required by the architecture build on the surface of each strip coal block, advancing coal mining for the 3-5 bone coals filling lane and then filling bone coals from the interior to the exterior inside the lane that has dug out coals. Ensuring the safety of the architectures, filling the displacement coal with bone coals, it can realize explorationrate no less than 20%, the total recovery rate of the strip mining area no less than 65%; Filling the mine with bone coals dug out can not only eliminates the bone coals on the land, reduces the encroachment of farmland, mitigates air and environmental pollution, gets rid of bone coal landslide or explosion and other hidden accidents that may affects the human life but also using bone coals working as the underground support of the mine and realizing second partial recovery for strip coal blocks under the architectures.

The invention discloses a large glass curtain wall supported by single cables. The large glass curtain wall supported by the single cables comprises a plurality of glass panels which are arranged side by side in the horizontal direction. The top end of each glass panel is clamped by a clamping component and installed on the lower side of a load-bearing supporting base in a hooked mode through a load-bearing hook. The bottom end of each glass panel is placed in a glass U-shaped bottom groove. Each inhaul cable is correspondingly arranged in a vertical gap of every two adjacent glass panels. The top end of each inhaul cable is connected with an inhaul cable tension keeping mechanism which is installed on a load-bearing adjusting base. The bottom end of each inhaul cable is fixedly connected with the ground through a lug plate. A plurality of connecting and supporting components are arranged between the top end and the bottom end of each inhaul cable. Each inhaul cable is clamped by one ends of the corresponding connecting and supporting components, and the other ends of the connecting and supporting components are placed in the vertical gap of the two corresponding adjacent glass panels and bonded to the corresponding glass panels. The single full-length glass panels are supported through the flexible single cables, the large-span full-glass curtain wall is obtained, and the glass curtain wall is ingenious in structure, simple in type, good in safety, very high in permeability and excellent in visual effect.

An apparatus for extinguishing a stovetop fire including a container detachably mountable to a microwave positioned above the stove top, the container having a closure retained in a closed position on the container. A projection member is connected to the container, the projection member retained in a retracted while the closure is in the closed position. A supply of fire suppressant material is retained within the container when the closure is in the closed position, the supply of fire suppressant material including a second burner portion positioned against the projection member. A heat responsive actuator is disposed on the container. When the container is mounted to the microwave over a first burner, and the fire actuates the heat responsive actuator, the closure moves to an open position and the projection member moves to an extended position, the projection member forcing the second burner portion toward the second burner.
