摘要:
Systems and methods for making and using a multi-blade collimator device are described herein. The collimator device can include a base member, a rotational member, and multiple X-ray-attenuating blades that fit together to define an aperture. The blades are typically disposed between the base member and rotational member. Additionally, the blades can be mechanically connected to or interfaced with the base member and the rotational member so that when the rotational member is rotated with respect to the base member, the blades move and cause the aperture to change in size. The aperture can be any shape, including polygonal, square, or rectangular. While the aperture's size can be increased and decreased, the shape and orientation of the aperture can remain substantially constant. The collimator can contain a single layer of blades or multiple layers of blades. Other embodiments are described.

Systems and methods for using a brake system to selectively lock and release the vertical motion of a C-arm X-ray device that is part of a sliding counterbalanced C-arm positioning device are described. In such systems and methods, the C-arm positioning device typically includes a C-arm X-ray device, a linear bearing rail assembly, a linear bearing block, a counterbalance mechanism, and brake system. Generally, the C-arm is connected to the linear bearing block, which is slidably coupled to the bearing rail assembly to allow the bearing block and C-arm to slide up and down on the rail assembly. The counterbalance mechanism applies a force to the bearing block to substantially counterbalance the weight of the components, such as the C-arm, that are suspended from the bearing block. The brake system can be actuated to engage the linear bearing rail assembly and lock the vertical movement of the linear bearing block. Other embodiments are described.

Systems and methods for making and using sliding counterbalanced C-arm positioning devices are described. In such systems and methods, each C-arm positioning device includes a C-arm X-ray device, a linear bearing rail, a linear bearing block, and a counterbalance mechanism. Generally, the C-arm is connected to the linear bearing block, which, in turn, is slidably coupled to the bearing rail to allow the bearing block and C-arm to slide up and down on the rail. The counterbalance mechanism can apply a force to the bearing block to counterbalance the weight of the C-arm and the bearing block. Thus, the described C-arm positioning device can allow a user to easily raise or lower the C-arm with relatively little effort. While some implementations of the C-arm positioning device are connected to mobile support structure, other implementations of the C-arm positioning device are mounted to a fixed support structure. Other implementations are also described.
摘要:
The present invention discloses apparatuses and methods for simultaneous viewing and reading top and bottom images from a workpiece. The present ID reader can comprise an enclosure covering a top and bottom section of the workpiece with optical elements to guide the light from the workpiece images to a camera. The optical element can be disposed to receive images from a high angle with respect to the surface of the workpiece. The present ID reader can further comprise a light source assembly to illuminate the image. The light source assembly can utilize a coaxial light path with the images, preferably for bright field illumination. The light source assembly can also utilize a non-coaxial light path, preferably for dark field illumination.

A heating and cooling device for temperature conditioning an air supply for an air conditioned appliance, said heating/cooling device comprising: a first air passage for channeling a first air flow; a second air passage for channeling a second air flow; an inlet fan for drawing air into said first, air passage; an exhaust fan for drawing air through said second air passage; one or a plurality of heat exchangers for exchanging heat between air in said first air passage and air in said second exhaust air passage; wherein said first air passage comprises a tubular channel having an inlet at a first end and only one outlet, said outlet being at a second end of said passage, and said inlet fan is positioned at said inlet, such that said first air flow is channeled through said inlet fan, along the whole of said air passage, encountering all of said one or plurality of heat exchangers, and out of said outlet.
摘要:
A wafer processing system and method in which a wafer, having a diameter, is movable between a loadlock and a processing chamber. A transfer chamber is arranged for selective pressure communication with the loadlock and the processing chamber. The transfer chamber having a configuration of lateral extents such that the wafer is movable through the transfer chamber between the loadlock and processing chamber along a wafer transfer path and the configuration of lateral extents causes the wafer, having the wafer diameter and moving along the wafer transfer path, to interfere with at least one of the loadlock and the processing chamber for any position along the wafer transfer path. The wafer includes a center and the wafer transfer path cab be defined by movement of the center through the transfer chamber. Swing arms are described that can independently move by different angles in opposing directions from a home position.

A vegetation pruning device (102) includes a pair (114, 116) of pivotably coupled handles and a motor having a rotary output drive (130) for driving an endless flexible cutting chain (108). A guard (162) is moved relative to the chain (108) by pivoting the handles (114, 116) relative to each other to grip vegetation between the guard (162) and the chain (108). The guard is provided with a pair of curved upper surfaces (164) having teeth (166). The rotary output drive (130) of the motor is arranged generally coaxially with the axis of pivotal movement of the handles (114, 116).
