    Abstract: This invention is an improved method and apparatus for tissue electrical impedance determination and electrical power control in a surgical device. In an embodiment of the invention an apparatus for controlling power delivery in an electro-surgical instrument is disclosed. The electro-surgical instrument includes a first channel and a second channel for delivery of energy to a surgical site. The apparatus includes: a switch, a measuring unit, a processor and a drive unit. The switch electrically isolates the second channel during a first measurement interval and the first channel during a second measurement interval. The measuring unit is coupled to the first and the second channel. The measurement unit measures a first power level of the first channel during a first measurement interval and a second power level of the second channel during a second measurement interval. The processor is coupled to the measuring unit and to the switch. The processor adjusts the first power level and the second power level to minimize a difference between a measured value of a control parameter and a target value of the control parameter. The drive unit is controlled by the processor. The drive unit delivers the adjusted first and second power levels to the surgical site via respectively the first channel and the second channel during a heating interval. In an alternate embodiment of the invention a method for controlling power delivery in an electro-surgical instrument is disclosed.

    Abstract: A photometer having a plurality of input fibers to its optical entrance, at least one of which is for transmission of calibration light and at least one of which is for transmission of sample light. The exit ends of these fibers are aligned into a linear array, thereby producing an effective entrance slit for the optical entrance of the photometer. The fiber(s) for calibration light are positioned at the center of the linear array to avoid miscalibration due to photometer astigmatism.

    Abstract: Apparatus and a method for providing measurements of the diffuse transmittance or reflectance of a sheet at a set of points arranged along a pattern line on the sheet. In accordance with the invention, the sheet, such as a photographic film, is moved with respect to a cylinder with a slot cut in its wall parallel to its central axis. A beam of radiation is swept parallel to the slot and into the cylinder after scanning along a line on the sheet. The inner wall surface of the cylinder is coated with a high reflectance material so that a fraction of the directly transmitted and scattered radiation in the cylinder enters one or more electronic radiation detectors coupled to the cylinder. The fraction of the radiation measured depends on the position along the slot of the radiation beam, and the data are corrected by dividing the measurement at each point by the measured radiation at that point when no object is in the beam. Several embodiments of the cylinder are disclosed.
