Abstract: Body armor for ballistic protection of a user's extremities preferably comprising right and left arm protection units and/or right and left leg protection units. The units include a ballistic protection material which preferably covers most of the user's upper arm, elbow region, lower arm, shoulder, upper leg, knee region, and lower leg except for ventilation zones preferably located on the inner portion of the upper arm and the inner part of the upper leg. The back of the knee is preferably covered by a protective flap.

Abstract: A protective cover for an electrical box of a type having vertical side walls embedded within a wall surface and enclosing a light switch or outlet protruding through an opening of the electrical box and beyond the plane of the wall surface has a rectangular box portion defining a peripheral dimension substantially similar to a dimension of the opening of the electrical box and has a cavity sized to receive the protruding light switch. Flanges extend outward laterally from the rectangular box portion and configured to rest on the wall surface. Further, side extensions coupled to the rectangular box portion and adapted to slidably engage with the vertical side walls of the electrical box to secure the protective cover in place.

Abstract: Program product to measure fluid flow characteristics in a pipeline is provided. A vortex-shedding body is positioned within the pipeline to form vortices. A vortex meter can include a vortex frequency sensor to measure the frequency of the vortices to determine the volumetric flow rate. A differential pressure meter positioned adjacent the vortex-shedding body can produce a differential pressure meter flow rate signal indicative of the density of fluid when flowing through the pipeline. A thermal flow meter positioned adjacent the vortex-shedding body can produce a mass flow rate signal indicative of the mass flow rate of fluid when flowing through the pipeline. The program product can include instructions for a fluid characteristic determiner to perform the operations of processing measured and sensed signals to produce an output of a volumetric flow rate, a flowing fluid density, and a mass flow rate to be displayed on a fluid characteristic display.

Abstract: A system to measure fluid flow characteristics in a pipeline, meter, and methods includes a pipeline having a passageway to transport flowing fluid therethrough, a process density meter including at least portions thereof positioned within the pipeline to provide flowing fluid characteristics including volumetric flow rate, fluid density, and mass flow rate of the flowing fluid, and a fluid characteristic display to display the fluid characteristics. The process density meter includes a vortex-shedding body positioned within the pipeline to form vortices and a vortex meter having a vortex frequency sensor to measure the frequency of the vortices and to determine the volumetric flow rate. The process density meter further includes a differential pressure meter positioned adjacent the vortex-shedding body to produce a differential pressure meter flow rate signal indicative of the density of fluid when flowing through the pipeline.

Abstract: An electronic whiteboard is coupled to a computer which receives information from the whiteboard indicative of graphical user inputs entered via a writing region of the whiteboard and control inputs entered via a control region of the whiteboard. A driver executing on the computer receives the information transmitted by the whiteboard, performs certain actions on the received information and causes an application program to retrieve the information and store the information to a session file. The application provides a user interface which allows a user to view images generated on the whiteboard, store such images, view previously stored images and to manipulate the images in a variety of ways.
