Abstract: Tissue access devices and methods of using the same are disclosed. The devices can have a sensor configured to occlude a flow path by deflecting a membrane into the flow path when the devices become dislodged from tissue. The sensor can be configured to partially or fully occlude the flow path. The sensor can have a spring. The spring can be biased to move the sensor from a sensor first configuration to a sensor second configuration when a force applied by the sensor first surface against a non-sensor surface changes from a first force to a second force less than the first force. The membrane can be deflected into the flow path when the sensor is in the sensor second configuration.

Abstract: A movable heat applicator is provided that is configured to treat a citrus tree for a bacterial disease. The heat applicator includes a heat containment structure that at least partially enclose a citrus tree. A steam generator adapted to produce steam is provided to release steam at a desired pressure and temperature for treating the citrus tree. A steam dispenser is connected to the steam generator and may be arranged in the interior of the heat containment structure at a positioned to dispense steam below branches of the citrus tree. The steam is dispensed into the heat containment structure to create a steam heated treatment environment to treat the bacterial disease. The movable heat applicator may also include a chassis coupled with the heat containment structure and a drivetrain that supports the chassis over a ground surface for moving the containment structure.

Abstract: Door frames, frame kits, component parts, jamb coverings, and depth extenders, all constructed with fiber reinforced pultruded structures, for entrance doors to buildings, both garage entrance doors and personnel entry doors. Some embodiments have a closed back wall. Others have an open cavity at the back wall to receive a reinforcing substrate. Some embodiments include a pultruded nosing block. Some embodiments comprise a pultruded depth extender, mountable on a jamb base to extend the depth of a door jamb. A mounting finger and a locking stud on the depth extender are mountable in cavities in the jamb base. A depth extender can be used to extend the depth of either a garage door frame or a personnel entry door frame. In an in-swing door frame, a door latch-side abutment surface is located on the side wall of the jamb base.

Abstract: An access door assembly for use in an air-handling unit provides a structural member that prevents over-compression of gaskets by the access door panel for improved gasket life and effectiveness and increases the thermal efficiency properties or the air-handling unit. The access door assembly has a “Z” shaped cross-section and includes a gasket channel and an anti-compression leg having a rim to prevent over compression of the gasket located in the gasket channel.

Abstract: Fiber reinforced polymeric pultruded cladding as jamb cover elements and mullion cover elements, for door frames and mullions, using pultruded structures as cladding over substrates. A jamb cover assembly includes a pultruded jamb plate and/or a pultruded nosing, and a mounting fin. The mounting fin extends from a distal side of the assembly. The frame can be secured in a doorway rough opening with the nosing assembled to the jamb plate, using the mounting fin for initial securement, optionally without assembly or disassembly of the frame at the construction site. Pultruded substrate covering covers both the outer surface and opposing sides of a mullion substrate. A pultruded mullion nosing is assembled to the substrate covering, and overlies part of the substrate cover, providing complete pultruded overlayment of the outer surface of the mullion substrate and spacing the front panel of the nosing from the outer surface of the substrate.

Abstract: An apparatus and method for an x-ray system includes an x-ray emitter having a first electrode and a second electrode. A high voltage supply is electrically connected to the first electrode. A power supply is electrically connected to the second electrode. A controller electrically connected to the high voltage supply and power supply is configured to provide a predetermined parameter to the second electrode during operation of the x-ray emitter to generate the predetermined dose rate from the x-ray emitter. During operation of the x-ray emitter, at least one operational value of the second electrode corresponding to the predetermined parameter is measured and combined with the predetermined parameter using an algorithm to obtain a modified predetermined parameter to be provided by the controller to the second electrode during a subsequent operation of the x-ray emitter.

Abstract: A diagnostic method for a gas supply system includes: determining a desired ramp rate for filling a vessel from a supply of compressed gas; monitoring the actual pressure of gas entering the vessel; and discontinuing the flow of gas into the vessel when the actual pressure deviates from the intended pressure at the desired ramp rate by an undesired amount. A system for carrying out the method includes a flow controller for controlling operation of the supply system to deliver compressed gas from a source to a vessel through a supply line at a desired ramp rate. The system employs a pressure monitor downstream of a control valve for measuring the pressure of gas directed into the vessel and transmitting pressure-related data to the flow controller, which closes the control valve to discontinue filling of the vessel if the actual pressure exceeds a permissible deviation from the intended pressure.

Abstract: A dental x-ray apparatus (10) includes a tube head (11) formed from a cast zinc material. Structural components of tube head (11) include such component (20) formed from a plastic material impregnated with a high molecular weight substance, such as barium sulfite. X-ray apparatus 10 has a control panel (15) in close proximity to the tube head (11), and is preferably DC powered.

Abstract: Gas compression system comprising a compression cylinder having a gas inlet, a compressed gas outlet, and one or more liquid transfer ports; a pump having a suction and a discharge; and a compressor liquid. The system also includes any of the following: a pressure intensifier having an inlet in flow communication with the pump and an outlet in flow communication with the compression cylinder; a feed eductor in flow communication with the discharge of the pump, with a reservoir containing a portion of the compressor liquid, and with the compression cylinder; a drain eductor in flow communication with the discharge of the pump, with the compression cylinder, and with a reservoir containing a portion of the compressor liquid; and a variable-volume compressor liquid accumulator in flow communication with the discharge of the pump.
