Methods and systems are disclosed for detecting overheating in an optical device before harmful consequences, such as severe local heating, can result. In one embodiment of the invention, a blackbody emitter is disposed in close proximity to a therapeutic optical fiber to absorb therapeutic radiation at a fault and re-emit blackbody (infrared) radiation. The emitter can be coupled to the fiber but, during normal operation, lies outside the optical path between the output of the laser radiation and the site of treatment. Systems and catheters incorporating such emitters are also described for effective monitoring of the laser power transmitted along the optical fiber within the phototherapy device.

The invention relates to iron coke for a blast furnace and a preparing method thereof. The iron coke comprises 5wt%-20wt% of iron ore powder and 80wt%-95wt% of mixed coal; the mixed coal is formed by mixing 25wt%-29wt% of one third of coking coal, 40wt%-44wt% of coking coal, 7wt%-11wt% of lean coal, 6wt%-10wt% of gas-fat coal and 12wt%-16wt% of fat coal; the iron ore powder and the mixed coal are mixed uniformly with water and tamped before entering the blast furnace, and are placed into the blast furnace when the temperature is 800 DEG C, the temperature is increased at the speed of 2 DEG C per minute to 3 DEG C per minute, the iron ore powder and the mixed coal are discharged from the blast furnace when the temperature is 950-1050 DEG C, and the iron coke is obtained by adopting a wet way of quenching the coke. According to the iron coke and the preparing method, the performance, the ratio, the particle size and the composition and the like of the iron ore powder and the mixed coal are optimized, and the strength and the reactivity of the iron coke can meet the requirement of the blast furnace process under the circumstance of not adding binding agents.

A scanning microscope includes a light source, illumination optics, and a scanning device for moving the illumination focus across a target region and doing so by varying the direction of incidence in which the illuminating beam enters an entrance pupil of the illumination optics. To incline the illumination focus relative to the optical axis of the optics, the scanning device directs the illuminating beam onto a portion of the entrance pupil that is offset from the center of the pupil and, in order to move the illumination focus across the target region, the scanning device varies the direction of incidence of the illuminating beam within said portion. An observation objective is provided which is spatially separated from the illumination optics and disposed such that its optical axis (O3) is substantially perpendicular to the target region and at an acute angle (α) to the optical axis (O1) of the illumination optics.

The present invention relates to a standup exercise apparatus that simulates walking and jogging with arm exercise. More particularly, the present invention relates to an exercise machine having separately supported pedals for the feet and arm exercise coordinated with the motion of the feet where the pedal stride length is determined by the movements of an operator. Crank arms are positioned on the framework forward the operator at a height comparable to the pedals. Compound guides are used to achieve elliptical curve pedal paths.

The invention discloses a high-stress roadway combined ring beam supporting structure and a construction method thereof, and belongs to the technical field of roadway construction supporting. The supporting structure comprises a roadway and a supporting ring. The homogeneous and isotropous supporting ring is constructed around the roadway, anti-pull anchor rods and slip casting anchor rods of different layers are relatively evenly arranged in surrounding rock, a relatively even steel wire rope net with main rope bodies of steel wire ropes as ribs and a multi-layer tough concrete gunite layer structure passing through a highly dense rock face are pressed below an anchor rod pressing disc of each layer, pressure stabilizing and pressure retaining gunite is applied to evenly gluing disperse and scattered surrounding rock, and the overall mechanical property is relatively even and is greatly improved. The cask effect of supporting is avoided, the overall bearing capacity of the surroundingrock is improved, the anchor rod combination number in unit rock bodies of the surrounding rock is increased, the manner singly depending on the strength of the rock is changed, the strength of the supporting ring is improved, and in combination with gluing of the gunite on the surrounding rock, the mechanical property of the surrounding rock is improved.

The invention provides a method for applying a light senor in a handset and a system thereof. The system comprises a photographic module, a baseband system, a screen backlight module, a keyboard lamp module and a screen display module. The method can adjust the display brightness of the handset according to the brightness of the screen and the keyboard demanded by human eyes in practical use of the handset, or can adjust the display brightness of the screen back light lamp and the keyboard lamp of the handset according to external light beams of different intensities, the power consumption of the handset is smaller, the battery is more durable, thereby realizing the functions of saving energy and power, the method utilizes the sensitivity of devices to the brightness, and a plurality of humanized and amusement functions can be developed on the basis of the sensitivity when users change the brightness artificially.

An exercise or fitness board having a deck adjustably attached to a base to adjust the angle of incline of the deck relative to the base, and a plurality of straps attached to the deck for the user to grasp for balance and exercise. The deck and/or base contains various contours, scallops, cutouts, and the like to facilitate comfortable and varied positioning of the body. A rail and/or channel may be placed on the underside and along the perimeter of the board to facilitate grip. A pad or mat may be placed on top of the board and/or base for comfort, stability, and protection.

System and a method for server recording and client playback of computer network characteristics. In general, the network simulation system includes a recording module that resides on a server and records and stores the network characteristics associated with networks sessions in a data collector file. The system also includes a playback module that resides on a client and receives the data collector file and plays back the data collector file upon request. The recording method of the present invention includes using a global filter residing on the server to record the network characteristics and storing the recording in a data collector file. The playback method includes receiving a data collector file containing recorded network characteristics recorded on a server and playing back the data collector file to simulate the characteristics of real-world network sessions.

A fluorescent pattern forming article including a first layer containing a metal ion, and a second layer disposed facing the first layer and containing a ligand coordinating with the metal ion contained in the first layer to thereby enable an intensity of fluorescence based on the metal ion to be changed.
