Surgical cutting and tissue vaporizing instrument

A surgical cutting and tissue vaporizing instrument, also referred to as an electrosurgical instrument, is in the form of a scalpel or scissors. The scalpel has a handle portion and a blade portion mounted on the handle portion. The blade portion has a smaller front section which acts as an active electrode, a larger rear section which acts as a return electrode, and an insulating middle section separating the two electrodes. A plurality of ports and conduits are formed in the blade portion, with the conduits extending through the handle portion, so that saline may be supplied to the handle and blade portions and out of the ports to the targeted area for tissue transection, and so that excess saline may be drawn by suction through other ports formed on the blade portion. The scissors include two cross-pivotally joined blades, each having a tip portion functioning as either an active electrode or as a return electrode. Ports and conduits are formed in each blade to elute saline onto the targeted area for tissue transection and to remove by suction excess saline from the targeted area.

Computerized system and method for teaching, learning, and assessing step by step solutions to stem problems

An online system provides for the teaching and learning of step by step solutions to STEM problems. The system comprises at least one tablet computer linked to at least one computer readable storage medium by a communication network. The computer includes an input device and a touch sensitive screen for receiving and displaying handwritten input. A system user inputs the computer with the steps of a step by step solution to a STEM problem by handwriting math expressions and sketches on the touch sensitive screen. The system evaluates and automatically color codes each step in accordance with a color coding protocol stored in the computer readable storage medium as each step is entered into the system. The color coding provides visual feedback which identifies correct steps, erroneous steps, and intermediate steps in the solution. Teachers use the feedback when teaching STEM solutions and students use the feedback when they are practicing and assessing their own solutions.

Crosslinked Organic-Inorganic Hybrid Membranes and Their Use in Gas Separation

The present invention is for crosslinked membranes and in particular for crosslinked poly(ethylene oxide)-cellulose acetate-silsesquioxane (PEO-CA-Si) organic-inorganic hybrid membranes and their use in gas separation. These crosslinked PEO-CA-Si membranes were prepared by in-situ sol-gel co-condensation of crosslinkable PEO-organotrialkoxysilane and CA-organotrialkoxysilane polymers in the presence of acetic acid catalyst during the formation of membranes. The crosslinkable PEO- and CA-organotrialkoxysilane polymers were synthesized via the reaction between the hydroxyl groups on PEO (or on CA) and the isocyanate on organotrialkoxysilane to form urethane linkages under mild conditions. The crosslinked PEO-CA-Si membranes exhibited both increased selectivity of CO2 / N2 and CO2 permeability as compared to a CA membrane, suggesting that these membranes are very promising for gas separations such as CO2 / N2 separation.

Automated calibration method and system for a diagnostic analyzer

A method to track stability and performance of diagnostic instrumentation, especially for veterinary automated hematology analyzers, applies a weighted moving averages algorithm to the diagnostic results of patient samples calculated by the analyzer. Control chart rules are used to set limits or ranges in order to determine if weighted averaged diagnostic results are within or outside of such limits or ranges. If the weighted average diagnostic results are outside of such control chart rule limits, then fuzzy logic and a gradient descent algorithm are applied to the weighted averaged diagnostic results.

Video surveillance system and method

A video surveillance system includes a first combiner, and a monitor, a power source and a camera control unit, each of which is electrically coupled to the first combiner. A regulated combiner located remotely from the first combiner and being electrically connected to the first combiner with at least one twisted pair of wires includes a voltage regulator which provides a regulated voltage to the camera located remotely from the first combiner. The camera is operable at a predetermined voltage level. The power supply provides an increased voltage to the regulated combiner through the first combiner and the twisted pair of wires to compensate for IR losses in the twisted pair of wires. Thus, the regulated combiner reduces the increased voltage to a safe level for the CCTV camera and other devices on a network to operate properly. The system dramatically increases the distance that a power supply can be located from where the camera is located, which decreases installation costs for CCTV surveillance systems.
