Abstract: Portable x-ray devices and methods for using such devices are described. The devices have an x-ray tube powered by an integrated power system. The x-ray tube is shielded with a low-density insulating material containing a high-Z substance. The devices can also have an integrated display component. With these components, the size and weight of the x-ray devices can be reduced and the portability of the devices enhanced. The x-ray devices also have an x-ray detecting means that is not structurally attached to the device and therefore is free standing. Consequently, the x-ray devices can also be used as a digital x-ray camera. The portable x-ray devices are especially useful for applications where portability is an important feature such as in field work, remote operations, and mobile operations such as nursing homes, home healthcare, or teaching classrooms.

Abstract: A radiation window device to transmit radiation as part of an x-ray source or detector includes a support to be subject to a substantial vacuum, and an opening configured to transmit radiation. A film is mounted directly on the support across the opening, and has a material and a thickness selected to transmit soft x-rays. An adhesive directly adheres the film to the support. A coating covers exposed portions of at least one of the evacuated or ambient sides of the film, and covers a portion of the support surrounding the film. The support, film and adhesive form a vacuum tight assembly capable of maintaining the substantial vacuum when one side is subject to the substantial vacuum. In addition, the vacuum tight assembly can withstand a temperature of greater than approximately 250 degrees Celsius.

Abstract: A latch for members that move at least in part slidably into a secured position is disclosed. The latch includes a cup adapted for mounting to a member such as a panel, door, cover, or circuit board, means for securing the cup to the member, a sliding member supported by the cup, a first linking member, and a second linking member. The sliding member is slidably movable relative to the cup. The first linking member is pivotally connected to the cup, and the second linking member is pivotally connected to the sliding member. The first and second linking members are pivotally connected to one another. The member to which the latch is mounted moves toward a secured position as the first and second linking members are moved to their respective closed positions while the sliding member is in engagement with a stationary keeper.

Abstract: A compression latch with a folding handle for selectively holding a door closed is disclosed. The latch includes a housing with a cup portion for receiving the handle in the folded down position such that the projection of the latch handle above the exterior surface of the door is minimized in the folded-down position. The handle functions to move a pawl in a combination of rotational and rectilinear movements as the pawl is moved between latched and unlatched positions.

Abstract: Latches including a housing, a rotary pawl, catch means for releasably holding the pawl in a closed configuration, and means for operating the catch means are disclosed. The pawl is pivotally attached to the housing and is rotationally movable between a closed or engaged configuration and an open or disengaged configuration. The pawl is provided with a torsion spring member that biases the pawl toward the open or disengaged configuration. In some embodiments the catch means includes a locking member. In other embodiments the catch means includes a pivotally movable trigger. The means for operating the catch means may be electrically powered.
