摘要:
The distributed bubble generating system intakes air and delivers this air at maximum capacity to the solution in the long-channel shape bubble generating units. The air is blown through the firm sponge type filters of the bubble generating units, which are submerged in the solution. This configuration provides the capability of rapid and effective generation of bubbles.

A narrow band x-ray filter can include: a substrate; and a sheaf of one or more reflection units stacked upon each other on the substrate. Each reflection unit can include: a first set of at least two discrete spacers on a respective underlying structures, a reflector disposed on the first set of spacers so as to form a void between the respective underlying structure and the reflector; and a first set of at least two discrete shims disposed on the first set of at least two spacers, each shim being at least substantially the same thickness as the reflector. A first device to produce a narrow band x-ray beam may include such a filter or an x-ray telescope. A second device to make an x-ray image of a subject may include the first device.

摘要:
A fluid status monitoring system for use in implantable cardiac stimulation or monitoring devices is provided for monitoring changes in thoracic fluid content. A fluid status monitor includes excitation pulse generating and control circuitry, and voltage and current measurement and control circuitry for performing a series of cardiac-gated, intra-thoracic impedance measurements. The cardiac-gated measurements are filtered or time-averaged to provide a fluid status impedance value, with respiratory noise removed. Based on comparative analysis of the fluid status impedance value, a clinically relevant trend in fluid status may be tentatively diagnosed and a fluid status response provided. Cross-check intra-thoracic impedance measurements performed using the same or a different excitation pathway and a different measurement pathway than the primary intra-thoracic impedance measurement configuration may be used to verify a tentative diagnosis.
摘要:
The present invention relates to a synthesis of an 8-membered carbocyclic compound having diexomethylene groups, more particularly to a synthesis of an 8-membered carbocyclic compound having diexomethylene groups, a novel compound having the structure represented by the following Chemical Formula 1, from trimethylsilanylmethyl-allenol derivative by the intramolecular Prins cyclization using Lewis acid. The 8-membered carbocyclic compound is a useful intermediate for synthesis of other multicarbocyclic compounds. In Chemical Formula 1, R1 is a phenyl group, and R2 and R3 is a hydrogen atom, or R1, R2 and R3 may be connected with neighboring substituents to form a 5 to 10-membered aliphatic or aromatic ring.

摘要:
Custom operations are useable in processor systems for performing functions including multimedia functions. These custom operations enhance a system, such as PC system, to provide real-time multimedia capabilities while maintaining advantages of a special-purpose, embedded solution, i.e., low cost and chip count, and advantages of a general-purpose processor reprogramability. These custom operations work in a computer system which supplies input data having operand data, performs operations on the operand data, and supplies result data to a destination register. Operations performed may include audio and video processing including clipping or saturation operations. The present invention also performs parallel operations on select operand data from input registers and stores results in the destination register.
