Abstract:
A high strength window for a radiation detection system includes a plurality of intersecting ribs defining a grid having openings therein with tops of the ribs terminate substantially in a common plane. The intersecting ribs are oriented non-perpendicularly with respect to each other and define non-rectangular openings. The window also includes a support frame around a perimeter of the plurality of intersecting ribs, and a film disposed over and spanning the plurality of intersecting ribs and openings. The film is configured to pass radiation therethrough. An associated radiation detection system includes a sensor disposed behind the window. The sensor is configured to detect radiation passing through the high strength window.

Abstract:
During each of frame periods, an image including gradation information is displayed at once on a display screen. Electrons are emitted in a second stage from all the pixels, independent of row scanning, separately from a first stage based on the row scanning. A display has a plurality of electron emitters arrayed in association with a plurality of pixels, and the image is displayed by electrons emitted from electron emitters. In each of the electron emitters, electrons are emitted from a first electrode toward an emitter to charge the emitter in the first stage, and the electrons are emitted from the emitter in the second stage.
Abstract:
A method and apparatus for generating membrane targets for a laser induced plasma is disclosed herein. Membranes are advantageous targets for laser induced plasma because they are very thin and can be readily illuminated by high-power coherent light, such as a laser, and converted into plasma. Membranes are also advantageous because illumination of the membrane with coherent light produces less debris and splashing than illumination of a thicker, solid target. Spherical membranes possess additional advantages in that they can be readily illuminated from variety of directions and because they can be easily placed (i.e. blown) into a target region for illumination by coherent light. Membranes are also advantageous because they can be formed from a liquid or molten phase of the target material. According to another embodiment, membranes can be formed from a solution in which the target materials are solvated. Membranes can be formed an a variety of ways, such as by rotating a circular apparatus through a reservoir of liquid target material such that membranes form across apertures that are disposed in the circular apparatus. Spherical membranes can also be formed by applying a gas (i.e. blowing) against a membrane formed in an aperture of a circular apparatus.
Abstract:
A controller handles host commands from a host processor and also interfaces the host processor to a serial device. Storage circuitry (e.g., a shift register) of the controller holds a predetermined plurality of data bits. State machine circuitry controls the storage circuitry for serial bit-level communication (e.g., using a PS/2 protocol) between the storage circuitry and the serial device. A processor executes code from a program memory. In particular, the program code causes the processor to detect that a host command has been received by the controller from the host processor and causes an action corresponding to the host command received. Because the processor is not involved with the serial bit-level communication between the storage circuitry and the serial device, the processor executing the software can handle host commands without affecting the serial bit-level communication.
Abstract:
A bus controller provided with a buffer memory performs DMA data transfer between a main storage unit of a system bus and an input/output control unit of a local bus. An interruption control section of the bus controller keeps an interruption signal at a response suppress section upon detection of an input/output end interruption signal from a unit on the local bus side, and thus suppress sending thereof to a processor of the system bus. When the end of data transfer to the main storage unit is determined from the data transfer monitor section in the interruption suppressed state, the suppressed state is released and an input/output end interruption notice is given to the processor. Even upon earlier end of data transfer on the local bus, therefore, consistency of data sent to the main storage is ensured.
Abstract:
A storage controller comprising a storage device adapter, a channel adapter, a cache memory, a control memory, and a plurality of buses connecting therebetween. The channel adapter communicates with a processor and processes input/output requests issued by the processor. The storage device adapter controls a storage device and data transfer between the storage device and the cache memory. The channel adapter and the storage device adapter exchanges control information via the control memory. The buses are used to transfer the data and the control information between the cache memory and the control memory, and the channel adapter and the storage device adapter. The controller also comprises bus load estimating means and bus mode selecting means. The bus load estimating means estimates bus load characteristics as an index based on the amount of data transfer during sequential access to the storage device. The bus mode selecting means determines a bus mode of bus utilization based on the index. Each of the channel adapter and the storage device adapter has bus access means for accessing the buses in accordance with the bus mode selected by the bus mode selecting means.
