The present invention provides an adaptive process control and profit depiction system which is responsive to both process measurement input signals, economic inputs, and physical environment inputs. The process control system features an interactive optimization modeling system for determining manipulated process variables (also known as setpoints). These manipulated process variables are used to position mechanisms which control attributes of a manufacturing system, such as a valve controlling the temperature of a coolant or a valve controlling the flow rate in a steam line.

A communication system transmits and receives a plurality of spread-spectrum signals having differences in at least one diversity parameter. The signals are highly correlated when their diversity parameters are similar, and the signals are uncorrelated when at least one diversity parameter is different. Any combination of a transmitter, a receiver, and a communication channel may diversity-encode the signals to effect differences in their diversity parameters. A receiver diversity-decoder compensates for differences in a diversity-parameter of at least one received signal to make the signal highly correlated with at least one other received signal. A correlator combines at least two of the received signals to recover an embedded information signal. The communication system enables the use of true-noise signals for spreading information signals, provides simplified receiver designs, and enables antenna arrays to spatially process spread-spectrum signals.

The density of at least one fluid in a pipe is determined using a pair of effective sound speeds a_1eff and a_2eff of the fluid/pipe system. The pair of effective sound speed measurements is taken at two sensing regions along the pipe wherein each of the sensing regions has a different cross sectional area compliance. The pair of effective sound speeds a_1eff and a_2eff is provided to signal processing logic 60, which determines the density of the fluid flowing in the pipe. The effective sound speeds a_1eff and a_2eff may be provided by a pair of sound speed meters positioned at the sensing regions wherein the sound speed meters utilize a spatial array of acoustic pressure sensors placed at predetermined axial locations along the pipe. The acoustic pressure sensors measure one-dimensional planar acoustic waves that are lower in frequency (and longer wavelength) signals than those used for ultrasonic flow meters, and thus is more tolerant to inhomogeneities in the flow. In addition, no external acoustic source is required and the meters may operate using passive listening.

When a mobile host or mobile router in nested mobile network is roaming in a domain with multiple mobility anchor points, if the mobile host or mobile router in the nested mobile network tree path chooses different mobility anchor points to derive its regional care-of address, routing sub-optimality may occur. To overcome such routing sub-optimality, this invention presents two main methods. The first method is where the mobile router detects that a downstream node in its tree path has derived a regional care-of address from another mobility anchor point, and will make appropriate on-demand duplicate registration at the other mobility anchorpoint. The second method is such that the mobile router informs its own mobility anchor point of other mobility anchor point addresses, so that the mobile router's mobility anchor point will pass the location entries of the mobile router to the other mobility anchor points.

The present invention provides an improved method of identifying which electrical conductor is supplying a signaling-point that is located on that conductor, in the electrical grid. The present invention makes the identification by measuring currents flowing into and out of a common connection-point, such as a power bus, and analyzing concurrent portions of these currents to determine whether they are ingress-current or egress-current over the analysis-intervals, and by a subsequent intra-bus and inter-bus analysis of the ingress/egress patterns. This is in contrast to prior art systems that rely on the measurement of signal strength, an approach that does not take best advantage of information in the signal because it fails to consider polarity of instantaneous voltages, reflective of the direction of current flow, or the intra-bus and inter-bus ingress/egress current-relationships.

The invention is focused on transforming untapped energy in man-made processes into electricity. The surplus power being targeted is contained within pipes where gases, liquids, or solids exert extra pressure. This can be a byproduct of a chemical reaction, occur during release of compressed gas, or result from gravity pulling material from an elevated physical position to a lower one. To harness this energy the invention consists of a micro-turbine, generator, sensors, processors, electronic controls, and communications equipment that operate autonomously. The electricity produced by the devices will be consumed by a generating entity, delivered to other end-users, or sold into the power grid. The invention will use information services, comprised of computer software, to acquire, store, and report performance and security information transmitted from remote locations to persons who work for the generating entity and/or other third parties.

A software mechanism for enabling a programmer to embed selected machine instructions into program source code in a convenient fashion, and optionally restricting the re-ordering of such instructions by the compiler without making any significant modifications to the compiler processing. Using a table-driven approach, the mechanism parses the embedded machine instruction constructs and verifies syntax and semantic correctness. The mechanism then translates the constructs into low-level compiler internal representations that may be integrated into other compiler code with minimal compiler changes. When also supported by a robust underlying inter-module optimization framework, library routines containing embedded machine instructions according to the present invention can be inlined into applications. When those applications invoke such library routines, the present invention enables the routines to be optimized more effectively, thereby improving run-time application performance. A mechanism is also disclosed using a “_fpreg” data type to enable floating-point arithmetic to be programmed from a source level where the programmer gains access to the full width of the floating-point register representation of the underlying processor.
