Title: Communications Protocol for Handling Arbitrarily Varying Data Strides in a Distributed Processing Environment
Inventor: COLEMAN RONALD G
IPC: G06F15/16
Filed: 1993-09-29
Abstract: Apparatus and an accompanying method for implementing a communications protocol for use in generally a distributed, and particularly a highly parallel,multi-processing system (5), for communicating application data of arbitrarily varying strides between separate processors and generally without the need for intermediate datastorage. Specifically, application data is transferred through a succession of packets (770) between originating and destination application programs (252), with each packetcontaining a partial data message. Each partial data message contains a portion of the data that is stored in a stride one portion of an originating application data memory (700). Upon reception, each data portion is written into a stride one portion of a destination application data memory (760). An application interface (254), executing independently at both the originating and destination processing elements (10 1, 10J+1) locally and respectively determines the starting address and length of each separate stride one data portion stored in the originating application data memory and for each separate stride one area in the destination application program memory that is to receive application data. Advantageously, through use of these independent application interfaces, application data can be transferred from the originating application data memory at one arbitrarily varying stride to the destination application memory with a different arbitrarily varying stride but without the need to pass the data through any input/output (I/O) buffers (632,634).

IPC: B03D1/02
Filed: 1993-10-07
Abstract: TAILINGS RETREATMENT     ABSTRACT OF THE DISCLOSURE     A process for recovering copper values from copper ore tailing streams with a conditioning step to mitigate the effects of prior contact with flotation reagents. Such a process is useful for recovering copper values from a copper ore final tailing stream with at least one conditioning under acidic conditions with a water soluble sulfide that converts the oxidized copper values into a collectable sulfide form. In live tailings, the rougher tailings stream are conditioned individually and subsequently combined with cleaner tailings concentrate for copper recovery by leaching. Separate treatment of the rougher tailings facilitates additional recovery of copper values.

Title: Active Energy Control for Diode Pumped Laser Systems Using Pulsewidth Modulation
Inventor: NIELSEN KEITH E
IPC: H01S3/115
Filed: 1994-01-20
Abstract: An active energy control circuit and method employing pulsewidth modulation for use with diode pumped laser systems. The active energy control circuit and method employs optical energy feedback sensing and output control of the electrical pulsewidth to pump diodes of the laser system. This creates an active energy control loop for maintaining diode pumped laser output energy at a desired level over different pulse repetition frequencies, time, and environmental conditions. The diode pumped laser output energy is controlled by varying the pulsewidth of the output energy pulse while maintaining a current amplitude set point. By using a pulsewidth-modulation-based control system, the current applied to the pump diodes is regulated at an efficient set point below their damage level, and the pulsewidth is adjusted to maintain a desired output optical energy of the laser system. The pulse width modulated output energy control scheme provided by the present invention is appropriate for all diode pumped laser applications including laser rangefinders, laser designators, laser radar systems, laser welding systems, and other low and high power laser systems.
