Abstract: A system for presenting meteorological information uses a browser interface to access massive amounts of weather-related data in the form of images stored on the server-side of the system. A user having a common browser on a Web client accesses the server-side information to selectively assemble weather-related data on multiple overlays of images and/or graphics into one simultaneous presentation on a Web page. The different overlays are normalized with respect to time and space, and a user can separately generate graphically miniaturized presentations of weather-related data for saving and subsequently recalling each presentation, wherein each presentation is displayed with current relativized data. The user can also select or customize derived variables to be distinctively displayed as part of a presentation.

Abstract: A drain assembly for a fluid collection container includes a housing attached to the container and defining a cavity therewithin. A stop is located within the cavity and is fixed relative to the housing. A switch having a closure member formed thereon is mounted within the cavity for rotary movement relative to the housing. In a disclosed embodiment the switch has a tab extending through the housing to facilitate rotation of the switch from outside the housing. A flexible, resilient tube in fluid communication with the interior of the fluid collection container has a portion disposed within the cavity and extending between the stop and the closure member of the switch. The tube is configured so that fluid discharged from the lower end of the tube is discharged through an opening in a lower portion of the housing. When the switch is rotated in one direction, the tube is compressed between the stop and the closure member, thereby preventing fluid flow through the tube.

Abstract: A detector assembly for a time-of-flight (TOF) mass spectrometer has a modular microchannel plate (MCP)-based detector and a replaceable MCP cartridge containing at least one MCP secured within the detector. The detector includes an integrated support for a voltage divider and high voltage connections. The detector is also adapted to be secured to a modified vacuum flange for the instrument.

Abstract: An adaptive thresholding technique is calculated by using a real-time 16 pixel running average (RA) 18 to which is added on offset value. The offset value 38 is the product of a programmable factor (alpha) and a Sum Absolute Difference (SAD) noise measurement. The adaptive threshold 42 is compared by a comparator 48 with a delayed analog video signal intensity value on line 46 for the pixel associated with the adaptive threshold. The comparator 48 provides a binary video output for further processing. A relative video output may also be provided by taking the difference of the analog video signal 46 and its corresponding running average 18.
