Abstract: A foldable table for use as a computer system workstation. The table includes an enclosure having opposing top and bottom panels, opposing front and back flanges and opposing end panels. A first rear leg is pivotally coupled to the top panel adjacent one end panel and a second rear leg is pivotally coupled to an opposite end of the top panel adjacent the other end panel. Both rear legs include a channel defined by opposing side walls. A first top support arm and a first front leg are pivotally coupled to the first rear leg, and a second top support arm and a second front leg are pivotally coupled to the second rear leg proximate the top panel. The first support arm and the first front leg are partially stored within the channel in the first rear leg, and the second support arm and the second front leg are partially stored within the channel in the second rear leg. An electrical outlet strip is rigidly mounted to an inside surface of the bottom panel.

Abstract: A bi-directional amplifier (10) for a transceiver module for amplifying both transmit signals and receive signals propagating in opposite directions. The amplifier (10) includes first and second common gate FETs (22, 24) electrically coupled along a common transmission line (20). A first variable matching network (28) is electrically coupled to the transmission line (20) between a transmit signal input port (12) and the first FET (22), and a second variable matching network (30) is electrically coupled to the transmission line (20) between a receive signal input port (14) and the second FET (24). An interstage variable matching network (32) is electrically coupled to the transmission line (20) between the first and second FETs (22, 24). A DC voltage regulator (34) provides a DC bias signal to the matching networks (28, 30, 32) and the FETs (22, 24) so that different signal amplifications and different impedance matching characteristics can be provided for the transmit signal and the receive signal.

Abstract: An optical device (10) including a first semiconductor layer (12) on which is deposited a dielectric layer that is patterned and etched to form dielectric strips (14) as part of a diffraction grating layer. Another semiconductor layer (16) is grown on the first semiconductor layer (12) between the dielectric strips (14) to provide alternating dielectric sections (14) and semiconductor sections. In an alternate embodiment, a dielectric layer is deposited on a first semiconductor layer (64), and is patterned and etched to define dielectric strips (66). The semiconductor layer (64) etched to form openings (68) between the dielectric strips (66). A semiconductor material (70) is grown within the openings (68) and then another semiconductor layer (72) is grown over the entire surface after removing the dielectric strips. Either embodiment may be modified to provide a diffraction grating with air channels (20).

Abstract: An EUV source (82) that delivers a laser beam (94, 96) asymmetrical relative to first collection optics (88). The first collection optics (88) has an opening (90, 92) for the laser beam (94, 96) that is positioned so that the laser beam (94, 96) is directed towards the plasma off-axis relative to the collection optics (88). Thus, the strongest EUV radiation (98, 100) is not blocked by the target production hardware (84).

Abstract: A processing engine (10) that generates sum of products (SOP) values for incoming data. The processing engine (10) includes a calculation module (30) for generating intermediate and SOP values based on the incoming data and coefficient values, wherein the intermediate values are defined by product values and partial presum values. A feedback module (50) stores the intermediate values until the calculation module (30) generates SOP values. The processing engine (10) further includes a reordering module (70) for reordering the SOP values. The feedback module (50) includes a switching mechanism (52) for retrieving intermediate values from the calculation module (30) until the calculation module (30) generates SOP values. Thus, a feedback RAM (53) can store the intermediate values without the need for buffering RAM at the input stage.

Abstract: An integrated planar antenna including a metalized ground plane printed on a dielectric slab. One or more slot antenna elements are etched into the metalized layer, and resonate at a particular resonant frequency band. A plurality of voids extend through the slab and act to vary the dielectric constant of the slab so that resonant waves are suppressed in the slab, thus reducing power loss in the antenna. The voids can be selectively localized in the slab to provide various functions, such as impedance matching and reduction of antenna element coupling. The voids can take on any shape and configuration in accordance with a particular antenna design scheme so as to optimize the effective dielectric constant for a particular application. In one particular design, the voids are formed in a random manner completely through slab, and the voids have an opening diameter less than {fraction (1/20)}th of the operational wavelength of the antenna.
