Thermal management in a printing machine for improvement of temperature response of printing process using design of experiments

The highly nonuniform transient power densities in modern semiconductor devices present difficult performance and reliability challenges for circuit components, multiple levels of interconnections and packaging, and adversely impact overall power efficiencies. Runtime temperature calculations would be beneficial to architectures with dynamic thermal management, which control hotspots by effectively optimizing regional power densities. Unfortunately, existing algorithms remain computationally prohibitive for integration within such systems. This work addresses these shortcomings by formulating an efficient method for fast calculations of temperature response in semiconductor devices under a time-dependent dissipation power. A device temperature is represented as output of an infinite-impulse response (IIR) multistage digital filter, processing a stream of sampled power data; this method effectively calculates temperatures by a fast numerical convolution of the sampled power with the modeled system's impulse response. Parameters such as a steady-state thermal resistance or its extension to a transient regime, a thermal transfer function, are typically used with the assumption of a linearity and time-invariance (LTI) to form a basis for device thermal characterization. These modeling tools and the time-discretized estimates of dissipated power make digital filtering a well-suited technique for a run-time temperature calculation. A recursive property of the proposed algorithm allows a highly efficient use of an available computational resource; also, the impact of all of the input power trace is retained when calculating a temperature trace. A network identification by deconvolution (NID) method is used to extract a time-constant spectrum of the device temperature response. We verify this network extraction procedure for a simple geometry with a closed-form solution. In the proposed technique, the amount of microprocessor clock cycles needed for each temperature evaluation remains fixed, which results in a linear relationship between the overall computation time and the number of temperature evaluations. This is in contrast to time-domain convolution, where the number of clock cycles needed for each evaluation increases as the time window expands. The linear dependence is similar to techniques based on FFT algorithms; in this work, however, use of z-transforms significantly decreases the amount of computations needed per temperature evaluation, in addition to much reduced memory requirements. Together, these two features result in vast improvements in computational throughput and allow implementations of sophisticated runtime dynamic thermal management algorithms for all high-power architectures and expand the application range to embedded platforms for use in a pervasive computing environment.

Next-generation patterning processes have been extensively studied recently, with a view to replacing the photo-lithographic process and to reducing production costs. For micron scale patterning, the printing process is one of major candidates. In particular, contact printing is more promising in view of the possibilities for mass production. In this process, the motion of the two printing contact surfaces should be synchronized perfectly to prevent slip and unwanted distortion in the surfaces and to make precise ink transfer between the surfaces. In this article, a force-based direct measurement method of the synchronization error is proposed, and the effect of synchronization error on the printing process is analyzed.

The existing system function as a multiple unit like computer setup and printing unit is fixed at different location and an intermediate person will be there to do the printing process. The existing system faces some difficulties like structure is not compact, all the units are installed at a different location, Customer needs 24*7 service, but the service is not available in all the times. The service timing is limited up to the availability of the labor. The Automated pay and use browsing, and printing machine is a type of vending machine which performs 24*7 browsing and printing service. The system can be implemented in the public places, educational institutions etc. The setup works on the time-based control system based on the amount paid as the input for browsing and printing separately. The main controller is the Raspberry Pi which controls and monitors the complete browsing and printing process. The separate coin collector device is interfaced with it to collect the amount for browsing and printing service. A continuous monitoring is done through IoT which helps to monitor the machine 24*7 which provides data like number of printout taken, browsing time. This makes the performance monitoring process easy

Electromagnetic Launcher

This paper presents a 3D model for the determination of the temperature field in an electromagnetic launcher. The large amounts of energy that are dissipated into the structure of an electromagnetic launcher during short periods of time lead to a complicated thermal management situation. Effective thermal management strategies are necessary in order to maintain temperatures under acceptable limits. This paper constitutes an attempt to determine the temperature response of the launcher. A complete three-dimensional model has been developed. It combines rigid body movement, electromagnetic effects and heat diffusion together. The launcher consists of two parallel rectangular rails and an armature moving between them. Preliminary results show the current distribution on the rail cross-section, the localized resistive heating, and the rail transient temperature response. The simulation results are compared to prior work presented for a 2D geometry by Powell and Zielinski (2008).

The purpose of this study is to improve theproduction process of brick craftsmen. Brick production processconsists of four stages: printing, drying, burning, and cooling. Ofthe four stages, which will be completed in this research is theprocess of printing bricks. The printing process still uses simpleequipment that is a rectangular wooden beam with a size of 20cm x 10 cm x 5 cm. The printing process includes: preparation ofraw materials by hoeing the soil, making the dough by tramplingto the shape of a paste, printing using a printing tool. For thismethod, for 4 people craftsmen can print bricks as much as 2,000pieces / day (8 hours work / day). The number of bricks is idealfor once combustion of 40,000 pieces. For reach that amount ittakes 20 days. The method applied in improving the productionprocess of brick craftsmen is the application of brick machine.The operation of the brick printing machine requires 4 personswith their respective functions: 1 person to insert the soil into theprinting machine, 1 person to cut the brick bar, 1 person to movethe bricks from the printing machine, 1 person to bring thebricks to the drying place. Based on the result of the test, it isconcluded that by using the brick machine, the dough making iseasier and shorter, the production capacity increased to 6,780bricks / day, the time required for the production of 40,000 piecesof bricks is 6 days.
