  • Publication number: 20250027893
    Abstract: A single MEMS thermal conductivity sensor based system capable of simultaneously measuring an air contained hydrogen and water vapor concentrations is described. The operation of the system is based on: hydrogen and water vapor have different temperature coefficients of their thermal conductivities and the sensor can be modulated by temperature so as to calculate their concentrations by their contributions to the total thermal conductivity of the air contained hydrogen and water vapor at different modulation temperatures of the sensor. The sensor comprises a one-dimensional gas heat conduction chamber recessed in a silicon substrate and a thermopile on the top of the chamber is used to measure the temperature difference between the heat source on the top and heat sink on the bottom of the chamber which is produced by the heat conduction of the air contained hydrogen and water vapor in the chamber.

  • Publication number: 20240385132
    Abstract: A dual MEMS thermal conductivity sensor configuration based microcontroller apparatus for monitoring of a vacuum drying process is described. Each MEMS thermal conductivity sensor comprises a resistor and a thermopile which are laid on a hotplate suspending over a buried cavity in a silicon substrate and operates by measuring the heat lost from the hotplate to the substrate using the thermopile which is heated by applying a voltage to the resistor. One sensor is open to the environment and used for measuring the thermal conductivity of the wet air in a vacuum drying container and the other is close to the environment and filled with dry air with one atmosphere and used for offset the static output of the measurement sensor.

  • Publication number: 20140182783
    Abstract: A two-liquid process for synthesizing polyurethane with high heat-resistance and high abrasion-resistance is disclosed, which utilizes a semi-reactive polymer A solution containing hydroxyl groups and a semi-reactive polymer B solution containing poly-isocyanate groups. The polymer A and B solution are mixed for performing a second reaction and then coated on a substrate by a coating machine, and the coating layer is cured to form a polyurethane film. The semi-reactive polymer A and B solution are pre-polymerized in advance. The required polyurethane resin expands on the semi-reactive polymer A and B with a whole range of new functionality and construction styles through polymerization to produce high heat-resistant and high abrasion-resistant polyurethane film through coating facility under the working temperature about 80° C. A fabric is coupled during coating step for polyurethane leather. The two-liquid process is without using solvent as carrier.

  • Patent number: 7376812
    Abstract: A processor can achieve high code density while allowing higher performance than existing architectures, particularly for Digital Signal Processing (DSP) applications. In accordance with one aspect, the processor supports three possible instruction sizes while maintaining the simplicity of programming and allowing efficient physical implementation. Most of the application code can be encoded using two sets of narrow size instructions to achieve high code density. Adding a third (and larger, i.e. VLIW) instruction size allows the architecture to encode multiple operations per instruction for the performance critical section of the code. Further, each operation of the VLIW format instruction can optionally be a SIMD operation that operates upon vector data. A scheme for the optimal utilization (highest achievable performance for the given amount of hardware) of multiply-accumulate (MAC) hardware is also provided.

  • Patent number: 6301704
    Abstract: A method, system, and computer product uses a hashed static single assignment (SSA) form as a program representation and a medium for performing global scalar optimization. A compiler, after expressing the computer program in SSA form, can perform one or more static single assignment (SSA)-based, SSA-preserving global scalar optimization procedures on the SSA representation. Such a procedure modifies, (i.e., optimizes) the SSA representation of the program while preserving the utility of its embedded use-deprogram information for purposes of subsequent SSA-based, SSA-preserving global scalar optimizations. This saves the overhead expense of having to explicitly regenerate use-def program information for successive SSA-based, SSA-preserving global scalar optimizations.

  • Patent number: 6128775
    Abstract: A method, system, and computer program product for performing register promotion, that optimizes placement of load and store operations of a computer program within a compiler. Based on the observation that the circumstances for promoting a memory location's value to register coincide with situations where the program exhibits partial redundancy between accesses to the memory location, the system is an approach to register promotion that models the optimization as two separate problems: (1) the partial redundancy elimination (PRE) of loads and (2) the PRE of stores. Both of these problems are solved through a sparse approach to PRE. The static single assignment PRE (SSAPRE) method for eliminating partial redundancy using a sparse SSA representation representations the foundation in eliminating redundancy among memory accesses, enabling the achievement of both computational and live range optimality in register promotion results.

  • Patent number: 6026241
    Abstract: Partial redundancy elimination of a computer program is described that operates using a static single assignment (SSA) representation of a computer program. The SSA representation of the computer program is processed to eliminate partially redundant expressions in the computer program. This processing involves inserting .PHI. functions for expressions where different values of the expressions reach common points in the computer program. A result of each of the .PHI. functions is stored in a hypothetical variable h. The processing also involves a renaming step where SSA versions are assigned to hypothetical variables h in the computer program, a down safety step of determining whether each .PHI. function in the computer program is down safe, and a will be available step of determining whether each expression in the computer program will be available at each .PHI. function following eventual insertion of code into the computer program for purposes of partial redundancy elimination.
