Abstract: A treatment pattern (such as a focused spot, an image, or an interferogram) projected on a treatment target may lose precision if the treatment beam must pass through a birefringent layer before reaching the target. In the general case, the birefringent layer splits the treatment beam into ordinary and extraordinary components, which propagate in different directions and form two patterns, displaced from each other, at the target layer. The degree of birefringence and the orientation of the optic axis, which influence the amount of displacement, often vary between workpieces or between loci on the same workpiece. This invention measures the orientation of the optic axis and uses the data to adjust the treatment beam incidence direction, the treatment beam polarization, or both to superpose the ordinary and extraordinary components into a single treatment pattern at the target, preventing the birefringent layer from causing the pattern to be blurred or doubled.

The system includes a plurality of perimeter Radio Frequency Sentry Devices (RFSDs) that are employed to establish the boundaries of said secure area around said wireless LAN. The wireless LAN being secured may be an industry standard IEEE 802.11a, 801.11b or 802.11g based wireless LAN or any other wireless LAN that uses packet based communication protocols. The said RFSDs may be stand-alone devices or they may be connected to a wired or wireless Local Area Network.

Abstract: A combinational transverse strut for a two-in-one arc-shaped or linear advertisement display frame, comprising a base body and a bendable overlay plate. Support members are provided at both ends of base body and overlay plate, respectively, each comprising a support seat, a support cap, a crankpin, and a magnetic steel. The crankpin is operatively connected between, and the magnetic steel is fixed between, the support seat and the support cap. The support member is connected to the base body by a straight pin shaft, and connected to the overlay plate by the crankpin. The two ends of the overlay plate are set up via support members to form an arc shape, so as to achieve applications as a linear member and as an arc-shaped member. The combinational transverse struts are attracted to each other by the magnetism of the support members.

The vehicle may include an elongate vehicle frame; a separating structure mounted on the vehicle frame and configured to contact the mixed debris stream with a fluid stream to separate the mixed debris stream into at least a first debris stream and a second debris stream; a first conveyor; a second conveyor; and a fluid collection structure configured to receive fluid from at least one of the separating structure, the first conveyor, and the second conveyor, the fluid collection structure including an upper tank, a lower tank, and one or more conduits fluidly connecting the upper and lower tanks, wherein the one or more conduits are free from a valve configured to regulate flow from the upper tank toward the lower tank.

Abstract: Embodiments of the present invention provide a vehicle disablement device that includes deployment of a tire puncture strip in front of the tire of a moving vehicle.

Abstract: A lens for a flashlight or other lighting unit provides for focusing light from a source, such as an LED, to provide a light beam adjustable between a spot beam and a wide beam. The lens includes a lens body with a front face, a rear LED-receiving well, and a side surface extending between the front face and the rear well. The front face includes a central surface surrounded by an annular concave surface. The rear well includes a space for the LED to be adjusted in position. The rear well space is defined by a concavely-curved sidewall and a concavely-curved base. The concave curvature of the sidewall and base may be Bezier curves.

Abstract: A device management system for securely storing an encryption key associated with a device management session. The device management system includes an encryption key generator to generate an encryption key, a client device to receive an encrypted bootstrap data file transmitted by a base station, and a network interface controller coupled to the client device, the network interface controller to store the encryption key separate from a system memory of the client device. Embodiments of the device management system ensure user credentials do not exist in the client device in plaintext form outside of the network interface controller, thus preventing software and/or malware executed on the host from extracting such credentials.

Abstract: A tree data structure for storing strings of searchable data divided into substrings has at least one first type node that has a substring associated with it and at least one second type node that does not having a substring associated with it. A second type node is directly linked to a first type node by a fail transition. A first type node is directly linked to a second type node by a match transition. An IP address lookup system has memory for storing a tree data structure and a controller for storing and loading an incoming IP address. The system has a finite state machine having three stages including a first stage for loading the IP address and performing a length calculation, a second stage for searching the data structure to find a match, and a third stage for determine the next-hop address index.

Abstract: A system for cooling and recuperative heating of a slurry in a metallurgical process which includes heat exchangers, pumps and autoclaves is described herein. The heat exchangers use a non-scaling common liquid heat transfer medium. Preferably, the heat exchangers are tube-in-tube heat exchangers with 3 to 7 slurry tubes in each heat exchanger. An advantage of this system is that it does not use flash tanks. To minimize abrasive wear on impinged surfaces, the velocity of the slurry is not more than 5 meters per second. The slurry comprises a solids concentration of 25% to 50%. Preferably, the pumps in the system are float-type pumps in which the driven liquid from the discharge pumps is also used as the drive liquid for the feed pumps.

Abstract: A dynamic random access memory integrated circuit and method includes internal refresh control and an array configured to receive read and write access requests having priority over pending refresh requests, wherein refresh requests are queueable and retired on clock cycles not requiring an access of the array and complete in one clock cycle. No on-board cache memory is required. A method includes: determining within the circuit when one of the banks of the array requires a refresh, prioritizing read and write access requests over pending refresh requests, read access requests initiating an access to the array without determining whether data is available from outside the array, and retiring within a clock cycle one pending refresh request to a bank when that bank has pending refresh requests and does not also require an access of the array on that clock cycle.

Abstract: Embodiments provide methods, apparatus, systems, and computer-readable media associated with using historic analytic data to identify shipping options for a user to use when shipping a package. Historic analytic data may be received and maintained by a package shipment facilitation system. The analytics may then be used to generate business rules which may be applied to parameters for a package that is to be shipped. Through application of the business rules, one or more preferred shipping options may be identified. Business rules may be received after being manually-generated by a user, or may be automatically generated based at least in part on the maintained historic analytics. After a shipping option is chosen for the package, a shipping label may be printed for the package, and the package may be entered into a carrier's system for processing.
