Raspberry Pi is a credit card sized Linux computer based on ARM 11 architecture. Because of its small size, low power consumption and powerful performance, a robot controller is a suitable role for it to play. As a robot with artificial intelligence, speech recognition for controlling the robot and voice feedback to users is key parts of the entire system. In this essay, a robot called Lisa is assembled, and a speech control and interactive system is implemented based on Google voice API which is a voice recognition engine provided as a cloud service, hi order to analysis complex voice commands, a semantic method is developed to catch key words from command sentences. Then try to make a pattern match between key words and instruction set build-in the robot control system. The speech recognition control and interactive system is effective and well behaved after experimental verification. © (2013) Trans Tech Publications, Switzerland.

During the process of generation and transmission, images will be influenced by the performance of imaging system, quantization noise or some other actors. The image will appear some phenomenons like clarity decrease and low contrast. For the sake of improving the picture quality in OLED system, time sequence control logic and hardware of the whole OLED system were implemented based on the detailed analysis of OLED panel electrical characteristics and various gray scale scanning principles. Sub-field scanning working mode is adopted in the design. Gray scale is 64 and vertical sweep frequency is 60Hz∼*** is the core control device in the whole system, the DVI decoded signal is processed. The design realizes the real-time video display on OLED. The utilization of parameters regulated homomorphic filtering technology is studied to improve the quality of color image. At first, the high and low frequency parts are departed with the help of illumination reflectance *** the digital image is processed with approximate high-pass filter, the simplified filtering algorithm made a compromise solution between the complex of hardware implementation and image quality. In the end, by the frequency domain inverse transformation, images got enhanced. The experiment results show that the particular information extrudes and the whole visual effect is improved after the process. © 2009 SPIE.

Optical tracking systems (OTSs) have been widely used in clinical practice to fulfill the high precision needs of contemporary surgery. The markers that are defaced in the production or surgery reduce the accuracy and tracking range of OTS. This effect was not considered in current products from either industry or academia. In this paper, we propose an OTS which can detect the defaced markers automatically. A stereo camera module is set to track surgical instruments by locating the markers affixed to them. An adaptive threshold approach is suggested to locate the markers. The typical fiducial localization error of our OTS reaches 0.28 mm, which is totally comparable to commercial devices. A defaced marker detection method based on the luminous energy model of OTS is proposed and can be used to recognize the defaced markers regardless of their relative positions to the OTS. © 2021 ACM.

International Symposium on High Density Packaging and Microsystem Integration (HDP)

With the increase in complexity of VLSI and the test cost of automatic test equipment (ATE), logic built-in self-test (BIST) has been widely applied. In order to reduce the test time of logic BIST, logic BIST with multiple scan chains has been proposed. However, the main shortcoming of logic BIST with multiple scan chains is low fault coverage (FC). A novel two-dimensional cellular automata (2-DCA), which is called two-dimensional restricted vertical neighbor cellular automata (2-DRVNCA), is proposed to resolve this problem. Using this 2-DRVNCA as pseudorandom test pattern generator (PRPG), high FC can be achieved. In the last, this PRPG is applied on some benchmark circuits of ISCAS'89, and average FC (82% ~ 89%) is obtained.

The narrow-band organic photodetectors based on organic photo-filtering layers using a transfer printing technology

Aiming at the response spectral of organic photodetectors (OPDs), we investigate a method of preparing the narrow-band near-infrared (NIR) OPDs by using thin film transfer print technology (TFTPT) to prepare the active layer of bulk heterojunction on the organic photo-filtering layer—a functional layer which can block some specific wavelengths of light and prevent these photons from reaching the next functional layer. Herein, short-wavelength photons are absorbed by the photo-filtering layer to form excitons, but they cannot be successfully dissociated due to the lack of a dissociation interface to the acceptor for eventual composite annihilation. While long-wavelength photons can effectively pass through the photo-filtering layer to reach the active layer and be absorbed and dissociated into free electrons and holes and eventually realize the narrow-band optical response. A narrow-band NIR OPD is prepared with a response peak of 790 nm and a full width at half maximum of 62 nm. Under the bias voltage of -5 V, the responsivity and specific detectivity of the device at 790 nm are 0.24 A/W and 1.39 × 1012Jones, respectively. The responsivity and specific detectivity of OPDs prepared based on our method can be flexibly adjusted by the combination of different photo-filtering and active layers, and the universality of our method is also proved.

Fluid dispensing was one of the main packaging technologies in the electronics industry. This study developed a control system for the adhesive jetting machine to match the no-contact requirement with high frequency and *** main control body was the computer and the control objects were the motion platform, jetting dispenser and temperature controller. The system had two control levels: the top level for the body and the bottom level for the objects. The developed software applied a hybrid programming based on Lab VIEW and Motion Assist 2.0 to provide a better operation performance and friendly interface. The prototype machine could achieve the programmed tasks after the mechanical structure and control system fabrication and the developed software installation.

More and more analog and mixed-signal (AMS) blocks are integrated into SoC (system-on-chip) platform due to intense market competition. In this paper we proposed a method for IP integration of mixed-signal SoCs. With continuous growing of design scale and complex validation of mixed-signal functions, a new verification methodology for large mixed-signal SoC designs using Synopsys Discovery AMS platform is given to handle the daunting challenge. We will give a brief introduction with an example of SoC design which contains a reusable 10-bit SAR ADC IP block. And the detailed flow of using NanoSim-VCS co-simulation environment for the example is elaborated.

The problem of signal detection and classification of multiple UAVs can be solved using object detection techniques in computer vision. However, this requires collecting and labeling a large amount of reliable raw data. Since the UAV signal dataset cannot be directly applied to object detection, we propose a method using time-frequency domain filtering and automatic labeling to construct a large-scale time-frequency spectrogram dataset. Experimental results show that the average recognition accuracies of image transmission signals and remote control signals under interference conditions are 97% and 82%, respectively, while the average errors of signal parameters are 0.93% and 5.57%. © 2023 IEEE.

Anisotropic conductive films (ACFs) are composed of an adhesive polymer matrix and fine conductive fillers using metallic particle or metal-coated polymer balls. Flip chip interconnection using ACF is being widely used in the electronic packaging. In this paper, two-dimensional nonlinear finite element analysis model was built to simulate effects of bumps' metallization on the stress and strain distributions of ACF interconnections for flip-chip-on-flex (COF) applications. The simulation results show that the bump metallization has big influence on the stress and strain. Under the thermal mechanical simulation, the stress is mainly relied on the Young's modulus of the bump while the strain is mainly depended on the CTE of the bump. In some kinds of bump/pad metallization, such as gold, nickel and copper, the copper has smaller stress, only bigger than gold, and minimum strain. If both chip bump and substrate bump fabricated by same copper, the galvanic corrosion, which occurs between two different metals and the main cause attributed to the shift of the contact resistance of ACF, does not exist. Regarding the cost and reliability synchronously, the copper may be the better substitute of gold as bump material in flip chip using ACF
