Abstract: One or more techniques and/or systems are disclosed for a flap valve in a diaphragm pump. The flap valve includes a body and a self-centering hinge portion. A front portion of the body includes a front surface having a raised portion and a recessed portion. The front surface is configured to form a seal with a surface of the pump when the body is in a closed position, the surface of the pump being at an inlet or an outlet of a pumping chamber. The body is configured to allow a downstream flow of a fluid when the flap valve is in an open position. The self-centering hinge portion is operably connected to the body. The self-centering hinge portion has a dynamically changing longitudinal axis. The body is configured to simultaneously translate and rotate about the dynamically changing longitudinal axis to form the seal.

Abstract: One or more systems are disclosed for leak detection for a pump that include a reservoir having a chamber with an inlet and an outlet. The inlet is configured to couple to an exhaust of a pump and the reservoir is configured to create a vortex flow therein. An optical sensor is positioned at a bottom of the reservoir with a detecting portion of the optical sensor extending into the chamber. The vortex flow causes one or more liquids to settle at the bottom of the reservoir on the optical sensor. The one or more liquids are indicative of a leak and the optical sensor is configured to detect the one or more liquids.

Abstract: A hip abduction pillow is used to prevent to post operative hip dislocation of a patient that received a hip prosthesis. The hip abduction pillow in may be integrally formed rigid foam or other suitable material and enables a single person to rotate the patient from side to side with virtually no risk of post operative hip dislocation while minimizing pressure on a patient's heels to virtually eliminate heel pressure sores. The hip abduction pillow includes a base portion; a support portion; and a spacer portion. The hip abduction pillow is self-supporting and can support the patient in two stable alternative rotated positions without the need for a pillow or other support material to maintain a patient in a rotated position.

Abstract: An intense field dielectric air filtration system includes a perimeter frame for wall or ceiling mounting at the inlet of a return air duct for an air conditioning apparatus. A door including a grille disposed thereon is mounted for movement on the frame between working and non-working positions for access to an air filter unit, a pre-filter unit and an intense field particle charging unit. Contacts on the filter unit and the field charging unit engage cooperating contacts on an enclosure mounted on the frame when the door is closed to supply electrical power. An interlock is provided to interrupt power when the door is moved to an open position or the grille is removed. A control system disposed in the enclosure includes user control features accessible when the door is in an open position. An alternate embodiment includes a support frame for positioning the filtration system in ductwork or the like other than a return air inlet.

Abstract: A realtime display compression for a waveform image uses a priority basis for combining groups of pixels when producing a compressed waveform image in order to preserve intensity information. As an example successive lines of data for the waveform image are demultiplexed into line buffers in a circulating manner, the number of line buffers being a function of the maximum desired integer compression ratio. The outputs from the line buffers are aligned and the corresponding pixels are combined according to a desired compression ratio, one output line for each integer compression ratio. The appropriate compressed line is selected as the output line according to the desired compression ratio, with the totality of the output lines forming the compressed waveform image.

Abstract: A test and measurement instrument includes a memory configured to store a digitized signal, a display configured to display the digitized signal, a mark interface configured to generate a mark creation signal, a processor coupled to the memory, the display, and the mark interface. The processor is configured to identify a feature of the digitized signal and create a mark indicating the feature and the digitized signal in response to the mark creation signal.

Abstract: A method is disclosed for forming an alcove in a rough opening for a standard door. The alcove is formed with a pair of converging side walls, disposed at an angle relative to the plane of the rough opening, which define a recessed door opening that is closed by an access door. The walls and the access door may be covered with mirrors forming a three-way mirror arrangement. In an alternative embodiment of the invention, the alcove is formed with a recessed wall relative to the plane of the door opening and one or more side wall doors. In order to facilitate construction of the alcove, a construction guide is disclosed which locates the positions of the side walls used to form the alcove. The guide as well as preformed structural members allow for relatively quick and easy construction of the mirrored alcove. Mirror panels are removably mounted for allowing relatively easy replacement of damaged mirrors.
