摘要： Energy output from a laser-produced plasma (LPP) extreme ultraviolet light (EUV) system varies based on how well the laser beam can maintain focus on a target material to generate the plasma that gives off light. The system and method described herein optimize EUV light generation by using a closed-loop gradient process to track and fine-tune in real-time the positioning of optical elements that determine how the laser beam is focused on the target material. When real-time alignment of the drive laser on droplet position is achieved, EUV generation is optimized.

摘要： An extreme ultraviolet light system includes a steering system that steers and focuses an amplified light beam traveling along a propagation direction to a focal plane near a target location within an extreme ultraviolet light chamber, a detection system including at least one detector positioned to detect an image of a laser beam reflected from at least a portion of a target material within the chamber, a wavefront modification system in the path of the reflected laser beam and between the target location and the detection system, and a controller. The wavefront modification system is configured to modify the wavefront of the reflected laser beam as a function of a target focal plane position along the propagation direction. The controller includes logic for adjusting a location of the focal plane of the amplified light beam relative to the target material based on the detected image of the reflected laser beam.

摘要： An inexpensive, aesthetically pleasing display assembly (10) is provided in the form of an upstanding carrier (12) supporting at least one comestible article (14) such as a multiple-piece simulated candy bouquet (15). The carrier (12) includes a pair of interconnected, angularly oriented panels (20, 22), with the panel (20) having an uppermost open mouth (72) and an elongated passageway (70). The simulated bouquet (15) comprises a plurality of candy pieces (16) each supported by an elongated stem (18). The bouquet stems (18) are inserted into passageway (70), and the panels (20, 22) are separated so as to form a stable, upstanding, self-supporting display assembly (10).

摘要： An automatic dual bobbin mechanism is provided. A housing containing two unique bobbin casings and bobbins therein oriented side-by-side with the sewing needle and thread passing between the bobbin casing pair replaces the convention single bobbin configuration. The bobbin pair acts in a tag-team operation whereby one bobbin supplies thread to be stitched into a fabric while the second bobbin is simultaneously filled with thread from an external source. When the first bobbin is emptied, the bobbin pair is rotated 180.degree. inside the housing. The second bobbin, now full, supplies thread for continued stitching while the first bobbin is refilled with thread supplied by the external source. The specially designed bobbins and bobbin casings allow for automatic rethreading of the empty bobbin and cutting of the bobbin thread from external source, thus eliminating the need to manually remove the empty bobbin and assembly, replace with a full bobbin and rethread.

摘要： A remote entry system for a vehicle includes a portable transmitter and a vehicle-mounted receiver. The receiver alternates between a monitoring state lasting for a monitoring period and a sleep state lasting for a sleep period. A remote control is manually activated and a message sequence is transmitted to the receiver in response to the manual activation for initiating a function of the remote entry system. The message sequence comprises a plurality of blocks transmitted at a predetermined block interval, the blocks including a preamble block and at least one message block. If the receiver detects the preamble block then it enters a reception state for detecting the message block. The preamble block has a predetermined preamble length and is comprised of a plurality of bytes separated by respective off intervals between successive bytes. Each off interval comprises a predetermined off period greater than the predetermined byte period. The predetermined off period is less than the monitoring period and the monitoring period is less than or equal to the predetermined off period plus substantially twice the predetermined byte period.

摘要： A system for treating water includes an ozone injector combined with a monitoring apparatus 400 that includes a flow meter 402 and a pressure sensor 404. The monitoring apparatus includes a flow path 424 having inlets 420, 422 communicating with the inlet 304 and outlet 306 of the ozone injector main water pipe 302. The flow path inlets are spaced respectively upstream and downstream of the ozone injection point. In operation, water filtered in filter 108 is ozonized in venturi 316 and then sterilized by UV lamp 210. The lamp is also used to generate ozone that is delivered to the venturi via check valve 308. The pressure sensor positioned within the flow path produces signals to control the switch of the UV lamp. The flow meter is used to determine when the filter should be replaced. The pressure sensor may be in the form of a silicon chip.
