Abstract: A solid-state thermal neutron detector comprises: a layered structure that includes; an electrically insulating substrate; a first electrode affixed to the substrate; a neutron-reactive layer affixed to and in ohmic contact with the first electrode; and a second electrode affixed to and in ohmic contact with the neutron-reactive layer; a voltage source electrically coupled to the first and second electrodes; and an electrical current detector electrically coupled in series between the layered structure and the voltage source.

Abstract: A water filter system comprising a control system, communication means, piping, actuators, sensors and valves. The control system utilizes a communication bus for controlling and monitoring water flow through the piping via control of the actuators and valves. The communication bus comprises a two-wire network in a loop configuration coupling the various actuators and valves to the control system. The control system includes a display and programmable control logic for monitoring and controlling the actuators and valves. In one embodiment, the communication bus adheres to a Actuator Sensor-Interface (AS-I) standard. The control system is further coupled to other control systems in a water treatment plant and a Supervisory Control and Data Acquisition (SCADA) network.

Abstract: A testing device for connection to a relay is provided. The testing device comprises a binding post and a test paddle. The test paddle includes a body portion, a stud, a contact and a handle. The body portion has a stud opening, a contact opening associated with the stud opening and a barrier extending from a first end of the body. The contact extends through the contact opening and is electrically coupled to the stud. The handle is coupled to the body and configured for grasping by an individual's hand to promote insertion and removal of the test paddle from the relay. The binding post includes a cover configured for rotating the binding post, the cover having an inner chamber for receiving an insert of the binding post. The insert is configured to couple test equipment to the stud on the test paddle for testing relay switches.

Abstract: A dasher board system for providing a surrounding barrier for the playing surface of a hockey rink. The dasher board system includes lower dasher board sections and extended continuous transparent upper shielding elements. The lower dasher board sections are formed by pultrusion. This gives the dasher board sections a high concentration of fiberglass and a high strength-to-weight ratio. This enables the sections to be made in longer lengths and reduces assembly time. The dasher board sections include horizontal ribs formed therein during the pultrusion process. A mounting system includes supports that are mounted to the horizontal ribs to stabilize the dasher board sections. Curved dasher board sections are formed by cutting the horizontal ribs and flexing the dasher board sections in the regions of the cuts. The transparent upper shielding is formed from by unrolling an elongated length of relatively thin polycarbonate material.

Abstract: A floor system having the versatility to be used for ice or in-line skating, ice, in-line, or floor hockey, or any other of a whole host of activities. The floor system includes a number of floor elements that extend the length of the playing or skating surface. The floor elements are interlocked with its adjacent floor elements to form a completed continuous upper planar surface. Supports, having fluid channels therein, support the planar upper surface a fixed distance from a foundation. The upper planar surface has a plurality of holes therein to permit fluid communication between the passages below the upper surface and the region immediately above the upper surface. This arrangement enhances the strength of the ice surface as the water that freezes inside the holes prevents portions of the ice from shearing off. Ice level indicators are frozen within the ice to provide a visual warning when the layer of ice falls below a predetermined amount.
