摘要： To synchronize the belt of a conveyor, a scanner, a fluorescent lamp, and an LED display unit of an area meter, the main AC power supply of the area meter drives the conveyor belt through a synchronous motor and supplies the same frequency of power to a phase locked loop. The phase locked loop provides synchronous pulses of higher frequencies to the scanning system, fluorescent lamp and LED display unit to maintain synchronism. The resolution of the measuring system is optimized when changes are made in the size of the area that is scanned by adjusting: (1) the lens of the scanner; (2) the rate of readout of the pulses from the scanner; and (3) the decimal place of the display unit. Travel from side to side of the belt is avoided by individually adjusting the ends of the pulleys until the belt runs true and an idler which lifts both bottom and top run of the belt when an object moves under it prevents slippage of the belt with respect to the rollers and the bite of the conveyor is adjustable.
摘要翻译：为了使输送机，扫描仪，荧光灯和区域仪表的LED显示单元的带同步，区域计量器的主交流电源通过同步电机驱动输送带，并将相同的功率频率提供给一个锁相环。锁相环为扫描系统，荧光灯和LED显示单元提供更高频率的同步脉冲，以保持同步。当通过调整扫描区域的大小进行改变时，测量系统的分辨率得到优化：（1）扫描仪的镜头; （2）从扫描仪读出脉冲的速率; 和（3）显示单元的小数位。通过单独调整皮带轮的端部直到皮带正常运行，并且当物体在其下方移动时，使皮带的底部和顶部行程升高的惰轮可以避免皮带的一侧到另一侧的行进，从而防止皮带相对于皮带的滑动滚筒和输送机的咬入可调。

摘要： To measure the density of a foilage canopy, an elongated average-light measuring instrument includes an elongated diffuser, an elongated quartz rod with a uniform diffusing groove in it between it and the diffuser and a photodiode at one end so that radiation hitting the diffuser enters the quartz rod and is transmitted to the photodiode to provide a measure of average light entering the length of the instrument. To digitize light instead of sensing average light, another embodiment includes a plurality of separate light entrances positioned along the length of the quartz rod and a scanner that scans across the rod or a uniform diffusing groove and circuitry that digitizes the electrical signal from the photodiode periodically in accordance with the position of the light scanner on the groove.

摘要： Systems and methods for measuring turbulent gas flux using high-speed vertical wind speed measurements (e.g., on the order of 5-10 Hz or more frequently) and low-speed gas content measurements (e.g., on the order of 5 Hz or less frequently), without the need for the sophisticated and expensive high-speed hardware to separate gas samples (e.g., into accumulation bags) according to updrafts and downdrafts. A time series of high-speed vertical wind speed data is used as a guide to distinguish between updrafts and downdrafts. When vertical wind speed is upward (updraft), the low-speed gas content is recorded into a data structure in one location, or marked with one flag. When vertical wind speed is downward (downdraft), the low-speed gas content is recorded into a different location, or marked with a different flag. Eddy Accumulation or Relaxed Eddy Accumulation computations can be performed using the stored gas content data to determine gas flux.

摘要： Systems and methods for automatically identifying and characterizing one or more lanes in image data for one or more electrophoresed samples. The method includes receiving data representing an image of one or more electrophoresed samples, segmenting the data into one or multiple data segments or portions within a region of interest (ROI), wherein the one or multiple data segments represent (e.g., when visually displayed) one or multiple lane segments along a first axis in the ROI, each of the one or multiple lane segments traversing one or multiple lanes in the image data, generating an intensity profile for at least a first data segment of the one or multiple data segments along a second axis orthogonal to the first axis, and processing the intensity profile to determine a location and parameters for each of one or multiple lanes in the first data segment.

摘要： Gas exchange analysis methods and systems utilize a water vapor buffering component including a material configured to buffer water vapor in a flow of a gas, whereby fluctuations in the water vapor content in the flow of the gas are slowed for components downstream from the water vapor buffering component. Components downstream of the water vapor buffering component may include: a first water vapor sensor configured to receive the flow of the gas from the water vapor buffering component and configured to measure a first concentration of water vapor in the gas; a sample chamber configured to receive the gas exiting the water vapor buffering component or the first water vapor sensor and to hold a sample capable of adding or removing water vapor from the gas; and a second water vapor sensor configured to measure a second concentration of water vapor in the gas exiting the sample chamber.

摘要： Machine-readable media and computer systems are provided for the highlighting of features in composite images through the alternating of images having complementary colors. An image having a feature of interest is used to generate one or more pseudo color images. A series of a pseudo color images and one or more additional pseudo color or original color images are then alternately displayed so that the differently colored regions among the series of images are easily recognizable to an operator. The differently colored regions differ in having hues that are complementary to one another. The methods are particularly useful for the display of information using two or more imaging modalities and channels, such as is the case for some medical applications in which a natural-light image of pink or light-red tissue with deeper red or blue vasculature is overlaid with another functional image. In these cases, a feature present in the functional image can be more easily perceived when displayed in a composite overlay with an underlying image from another imaging modality or channel.
