Abstract: An ultrasonic coupling device. The ultrasonic coupling device includes a hydrogel wherein the hydrogel has a water content of at least 10 wt %; and a near field communication device.

Abstract: Acceptable memory allocation for a partition is determined during and with minimal impact on normal operation of the partitioned system. The approach includes: collecting, by a processor, statistics on a rate at which pages are transferred between uncompressed and compressed memory spaces of the partition's memory; adjusting size of the uncompressed memory space; and subsequent to the adjusting, continuing with collecting of the statistics, and referencing the resultant statistics in determining an acceptable memory allocation for the partition. In one implementation, the adjusting includes stepwise decreasing size of the uncompressed memory space by reallocating uncompressed memory space to compressed memory space, and repeating the collecting of statistics for a defined measurement period for each adjusted uncompressed memory space size until performance of the partition is negatively impacted by the reallocation of uncompressed memory space to compressed memory space.

Abstract: In a NUMA-topology computer system that includes multiple nodes and multiple logical partitions, some of which may be dedicated and others of which are shared, NUMA optimizations are enabled in shared logical partitions. This is done by specifying a home node parameter in each virtual processor assigned to a logical partition. When a task is created by an operating system in a shared logical partition, a home node is assigned to the task, and the operating system attempts to assign the task to a virtual processor that has a home node that matches the home node for the task. The partition manager then attempts to assign virtual processors to their corresponding home nodes. If this can be done, NUMA optimizations may be performed without the risk of reducing the performance of the shared logical partition.

Abstract: A laser fluid control apparatus and method provide selective, precise control of the fluid supplied to the laser. The flow of the fluid to the laser can be automatically adjusted according to a selected, programmed control to provide a high volume of the fluid to the laser during initial operation of the laser for a quick warm-up of the laser and a reduced volume after the laser has warmed-up for more economical operation of the laser. Different fluid mixes can also be provided for enhancing laser performance. A control for pulsed or continuous wave laser operation can be actuated to automatically change the composition of the fluid supplied to the laser for continuous wave laser operation as compared to that for pulsed operation.

Abstract: An improved method of laser processing of a material by directing a laser beam against the material comprises providing the beam with a power waveform with respect to time characterized by a plurality of peak power pulses and a predetermined CW power level between the peak power pulses such that the average beam power maintained is equal to or greater than the predetermined CW power level of the beam. The method is particularly adapted for cutting material such as aluminum, copper and stainless steel with improved cut quality at a relatively high cutting speed and for welding.

Abstract: Method and apparatus for handling compactible articles, and particularly recyclable articles includes a housing forming a compaction chamber with a bottom door movable between a closed position and an open position and having a feed opening through which articles are passed to be collected in said chamber. A retractable loading chute into which articles are discharged directs the articles into the feed opening when in the open extended position is movable to a retracted position to form wall portion of said chamber closing the feed opening. A first drive has a platen that is moved between extended and retracted positions in said compaction chamber to compress the collected articles in the chamber into a unitary block of mechanically interconnected compacted articles and move the block from the chamber. A second drive connected to the bottom door moves said bottom door between a closed position for compaction and a retracted position for the discharge of said block from said chamber.
