The present invention provides a method and system for controlling leakage power consumption at a System on Chip (SoC) level during a normal run or a boot-up mode. The leakage power reduction is achieved by incorporating a central programmable controller in the SoC architecture and test structures of idle SoC peripherals to place them into an Absolute Minimum Power consumption state with respect to static and dynamic power.

The invention discloses an asymmetric square wave modulation method to measure interference fiber gyro eigenfrequency. By controlling module FPGA, the method controls DDS to generate different frequency asymmetric square wave to process phase modulation to Y waveguide; and the signal processing module DSP real-time calculates the margin absolute DeltPd of the accumulation in A/D sampling time T, and processes the absolute minimum judgment to the said margin absolute DeltPd, and when the margin absolute DeltPd close to zero, gets the fiber gyro eigenfrequency fe equaling modulation frequency fd. Such measurement method measures the eigenfrequency Fe with high accuracy, and frequency tracking speed adjustment quick, and highly real-time.

A flow-through pressure sensor apparatus that reduces the dead space of a flow tube utilized to provide fluid communication between a pressure sense die and a fluid and with an absolute minimum trapped volume. A cover (e.g., plastic) with two-molded ports can be added to one side of the pressure sense die utilizing molded-in solder pins to improve ruggedness and rigidity. A temperature and a humidity sensor can also be mounted to a substrate (e.g., ceramic) in the flow path and can be connected to a programmable compensation integrated circuit on the opposite side utilizing a clip end of mounting pins or by vias through the substrate outside a pressurized area.

Methods and systems for performing arithmetic functions. In accordance with a first aspect of the invention, methods and apparatus are provided, working in conjunction of software algorithms and hardware implementation of class network routing, to achieve a very significant reduction in the time required for global arithmetic operation on the torus. Therefore, it leads to greater scalability of applications running on large parallel machines. The invention involves three steps in improving the efficiency and accuracy of global operations: (1) Ensuring, when necessary, that all the nodes do the global operation on the data in the same order and so obtain a unique answer, independent of roundoff error; (2) Using the topology of the torus to minimize the number of hops and the bidirectional capabilities of the network to reduce the number of time steps in the data transfer operation to an absolute minimum; and (3) Using class function routing to reduce latency in the data transfer. With the method of this invention, every single element is injected into the network only once and it will be stored and forwarded without any further software overhead. In accordance with a second aspect of the invention, methods and systems are provided to efficiently implement global arithmetic operations on a network that supports the global combining operations. The latency of doing such global operations are greatly reduced by using these methods.

In a heddle (6), the slender heddle shank (21) has been lengthened, at the cost of the end eyelets (7, 8) and the yarn eyelet region (29). This is accomplished on the one hand by shortening the end eyelet regions (7, 8) to their absolute minimum length and on the other by placing the auxiliary openings (38), which serve to transport the heddles, closer to the end eyelets (7, 8). The radii R in the region of the end eyelets (7, 8) are reduced. Instead of the usual 2 mm width, the heddle shank (21) still has a maximum width of 1.6 mm. The regions (14, 13) of the heddle (6) that protrude past the end openings still have, instead of the usual length of 4 mm, a length of 2.5 mm to 3 mm. Directly around the yarn eyelet (33), the heddle has a width which, as before, is equivalent to twice the width of the yarn eyelet (33). However, the length of this region is shortened to a maximum of twice to three times the yarn eyelet width. The transition from the narrowest zone (27, 28) of the heddle shank (21) to the comparatively wide zone (29) around the yarn eyelet (33) is characterized by an elongated transition region (34), which has a maximum width of 1.8 mm and serves to reinforce this region against mechanical stresses.

A system for recovering CO2 via liquefaction and purification from a vented CO2 gas stream comprising a compressor; a dehydrator; a scrubber; a refrigerator having one or more stages; and a separation subsystem adapted to ensure non-condensable gas content in the final product meets industry standards. The liquid CO2 product is of sufficient purity to be used in applications requiring beverage-grade CO2. The system can be utilized as a single-brewery installation to reduce venting from ethanol fermenters to an absolute minimum, produce a high purity liquid CO2 product for use in-process or external sales, and offset the purchasing of expensive, industrial CO2 of inferior purity.

A method, computer program product, and data processing system for managing a input/output buffer cache for prevention of deadlocks are disclosed. In a preferred embodiment, automatic buffer cache resizing is performed whenever the number of free buffers in the buffer cache diminishes to below a pre-defined threshold. This resizing adds a pre-defined number of additional buffers to the buffer cache, up to a pre-defined absolute maximum buffer cache size. To prevent deadlocks, an absolute minimum number of free buffers are reserved to ensure that sufficient free buffers for performing a buffer cache resize are always available. In the event that the buffer cache becomes congested and cannot be resized further, threads whose buffer demands cannot be immediately satisfied are blocked until sufficient free buffers become available.

A state where at least a part of the virtual object (e.g., a foot of a robot) enters into the actual object (e.g., floor), i.e., a state where at least a part of a plurality of virtual points located on the surface of the virtual object is inside the actual object, can be assumed. At each of the inside and the outside of the actual object, as a virtual point is located at a deeper position inside and away from the surface or the skin part of the actual object and as a coordinate value difference ΔZ_i is larger, a higher value is calculated for the cost E_i as well. The combination Ẑ of coordinate values of virtual points, bringing the total cost E=Σ_iE_i closer to an absolute minimum or a local minimum, can be searched.

For an internal combustion engine with a common rail system including individual accumulators, a process for open- and closed-loop control is proposed, in which the individual accumulator pressure (pE) is detected within a measuring interval and stored, an absolute minimum value of the stored individual accumulator pressure (pE) is interpreted as the end of the main injection, and on the basis of the end of the main injection, a mathematical function is used to calculate a virtual starting time for the main injection. In the measuring interval after the end of the main injection, the individual accumulator pressure (pE) is filtered within a time window, a local minimum value of the filtered individual accumulator pressure is interpreted as the end of a post-injection, and a mathematical function is used to calculate a virtual start of the post-injection.
