automatic device

Wireless sensor network is a network composed of a large number of cheap wire- less sensor nodes. It is a kind of computer network composed of many automatic network device randomly distributed in space. These devices use sensors to coopera- tively monitor the environment situation or physical information of different loca- tions, such as temperature, humidity, smell, sound, vibration, pressure, motion or pollutants [1]. The development of wireless sensor network originated in battlefield monitoring and military applications. But now it is used in many fields, such as envi- ronmental and ecological monitoring, health monitoring, home automation, bio medi- cal, emergency rescue and disaster relief, remote control of hazardous area, traffic control and so on [2]. It is a hot research field in the world, which involves many disciplines, high cross and highly integrated knowledge. These applications cannot be separated from positioning technology as the support.

Echocardiography has been considered the gold standard tool in patients undergoing optimization of their AV and VV timings. Nevertheless, it is relatively costly, time consuming, requires skill and expertise to be accurate, and, because opti- mal intervals often change over time, may require systematic validation to improve CRT effectiveness. The availability of an effective automatic optimization algorithm capable of a systematic adaptive optimization of AV and VV intervals in concordance with echocardiographic-based methods could change clinical practice in this important field. In order to investigate further this question, the concordance of optimal AV and VV intervals between echocardiographic-based assess- ment and an automatic device programming using the available hemodynamic sensor algorithm SonR was evaluated in the first 6 months after CRT implant, and CRT response was recorded up to 6 months of automatic optimization.

Abstract The purpose of this paper is to design a new concept of an automatic compaction device for composite panel production at layup process in one of the aircraft composite panel manufacturers in Malaysia, known as Company A. The current compaction process in company A requires an implementation of an effective and automatic vacuum bagging/compaction process to replace the current manual way method. The objective is to implement an automatic device to be integrated with the current method in order to make it simpler and more efficient for the operators to do the compaction process. This method could avoid human error in compaction timer hence reducing completed panel defect rate. Vacuum bagging/compaction process is a very important process to consolidate the laminates into a composite. Hence it is important for the precision of vacuum pressure and timing for the compaction process. The automatic device is designed to do the compaction process according to the timer automatically. The approach of designing this device is to use timer and solenoid valve to control the vacuum and a timer with a microcontroller. This device implementation will also reduce the steps of compaction process compared to the current way of doing so in Company A. In addition, it is believed to reduce the redundancy of work of the operators and increase multitasking of the operator and yield of composite panel produced by the company.

The multi-functional automatic device has many unique advantages and functions. There are two integrated cylinders with lifting hinges between the catwalk and the ramp. The angle of pipe entering the drilling floor can be adjusted arbitrarily by the cylinder. There is no connection between ramp and drilling floor. The thrust unit of the automatic catwalk is used to adjust the position of the pipe in the ramp, and the thread cleaning device, greasing device and thread protection device are designed. When the drill tool is on the drilling floor, the pipe is fed into the catwalk from the ground pipe rack. Driven by the driving device located at the end of the catwalk, the pipe moves toward the ramp. At the same time, the lifting cylinder on the base lifts the catwalk, and the driving cylinder between the catwalk and the ramp extends to adjust the position of the ramp. According to the height of drilling floor, the angle between catwalk and ramp can be adjusted to transport and receive single drill pipe, collar and casing. The drill pipe conveying system is installed on the opposite side of the driller, which can push a single rod onto the ramp. The casing conveying system is located at the driller's side, and the front end of the string is pushed forward by a pusher, which is connected by a top drive sling or a drilling rig pipe handling system. The process of laying down the drilling tool is contrary. Its main technical parameters are as follows.

The current technology of daily sampling and microscopic observing of the active sludge in the sewage treatment plant is entirely artificial mode, which is completely relies on the manual producing glass slides, observing and counting, and even cleaning. The microscopic inspection process is tedious and heavy, which is easy to cause visual fatigue and miscount. Thus it is necessary to develop an automatic device, namely an automatic glass slide, which can be used for the active sludge sampling and microscopic observing.

work more than 8 hours without charging. Fig.4 shows the PCB module of the wearable guide device. There is a coil fixed on the PCB to provide a wireless charging function. Fig.5 shows a photo of the trial manufacture device. The weight of the device is less than 40g, it is light enough for wearing on the ear for a long time. As wireless communication, we developed our own communication protocol, which can reduce power consumption greatly compared with fashionable wireless communication such as Wi-Fi, Bluetooth. Therefore, the new wearable guide can provide a much longer operation time. For a guide system in exhibition facilities, it is important that the wearable guide device can provide guidance service without charging for the total opening period of tourist facilities. In the design of the wearable device, it has become important to extremely reduce the power consumption of the communication function and the reproduction function in order to realize long-time operation and weight saving.

In order to verify the experiment results, it is necessary to study on the early experiments on the ground first [1]. The big bubble gathered floats in the waterway has an irregular shape because of the influence of gravity. Therefore, the device is placed one side tilt in the simulation experiment, as shown in figure 7, making a large number of small bubbles gather at the corner of the bubble trap into a big one. The shape of the gathered bubble is just like a triangular prism, which is very convenient to calculate the volume of a bubble by measurement.

Photoelectric tracking is through the photosensitive sensor (such as silicon photovoltaic tube) for detecting sunlight. The basic principle is: when photosensitive sensor installed fixed on the tracking device. When the sun shifts, the photosensitive device will receive current deviation. A series of magnification shaping, digital-to-analog conversion and calculation processing acquires the tracking signal. Through the tracking signal, servo action in driven to adjust the device to achieve accurate tracking [18]. Photoelectric tracking based on the detection of diff erent devices (such as photosensitive resistors, photodiodes, phototransistors, etc.), constitute different performances of the sun tracker. The advantage is that it is not aff ected by geography and winter and summer time diff erence. It is easy to use, fl exible, simple in structure, low in cost and more accurate. The tracking accuracy of reference [18] can reach 0.003 ° [19]. However, the sensitivity of the sensor is poor, subject to relatively large external environment changes, especially during cloudy weather, bright spots on cloud will cause the tracking device to tremble, seriously aff ecting the normal function [20].

A kind of chain forming device is proposed in this paper to realize a non-woven bag automatic processing. This device are mainly composed of a chain transmission mechanism, a guide rail, a pull-apart mechanism, a cutting mechanism, a pressing and transmission mechanism, a leveling mechanism, a bag-body conveying mechanism and a sewing mechanism, and so on(Figure 3).

The drop angle defines the ratio of the vertical to horizontal displacements of the workpiece on a vertical chuck face. The presence of a drop angle means is that if the highspot is tapped, the part will not move directly towards the center of rotation. With high drop angles values, the alignment algorithm can take an unreasonable amount of time to align a part or simply be unable to align a part if compensation is not used. The drop angle is only an issue if the part is being tapped at the side (i.e. perpendicular to gravity) on a vertical chuck. This orientation is necessary for size constraints as the device described in Section 2 cannot fit underneath a workpiece and the new device described in Section 3 was designed to be held by a standard tool holder.

transplanting machine for dry land. It is composed of a tray device, a seedling collecting device, a seedling feeding mechanism with square cups, and a seedling throwing mechanism. The seedling collecting device consists of a row of seedling collecting fingers. The seedling is taken by grabbing its stem and the seedling throwing mechanism uses a cup-type planter. The machine was improved on the basis of the semi-automatic transplanting machine, but because the seedling was taken by clamping, it was required that the diameter and toughness of the seedling stem are high. Chen et al. [17] and Wang et al. [18] built models to simulate the transfer and delivering system of seedling transplanting. The conveyor belt combined with the guide wheel was used to line up the potted seedlings, and pots splitting device with double pin and seedling dropping device with trigger tray were driven by cam disc. But the study did not address the problem to move the seedlings from the tray and place them on the conveyor belt.

In industrial nowadays, packaging is a stage that is important because to make a product safe and good in condition when delivering to customer as well as to both sellers and buyers of the products. Most commercial packaging serves two basic functions which are protecting the product from damage during shipping, and promoting the product to the ultimate consumer. Operators must pack the boxes carefully so the products still in good condition but it will take a time if the operators have a lot of boxes to package. Therefore, this project an automatic box packaging device will make the process become fast that replaces the operator for packaging the boxes. An automatic box packaging device will be adaptable to production-line speeds, increase the product's density, and satisfy legal requirements.

The room inside of a greenhouse has a different treatment from the outside environment, and several parameters need to be engineered properly according to the plant's needs for optimal growth, these parameters are but not limited to temperature, humidity, and light intensity [6]. These microclimate control can be done with a cooling system. A cooling system is a device that is installed in a greenhouse to reduce air temperature and increase the humidity inside, one of the cooling systems that can be used for greenhouses is misting cooling system [7]. Misting cooling system is a cooling system that uses water as its cooling subject, the water is released through a nozzle with a high-pressure pump and forms a smooth splash of water (dew), it can be done manually but the tool needs to be controlled by an operator for 24 hours. This condition requires an automatic control system for the tool to run by itself without having to be controlled intensively.

Even when tested on portable devices, our me- thod was able to perform faster with a lower mean error than that of the method of Carneiro. In addition, our method does not require a big data set of images for training a classifier that the Carneiro method requires. The error ranges of these automatic methods differ greatly from the manual inter-observer variabil- ity (−21.7 to 23.7 mm) reported by Perni et al . (2004) [12], which was calculated from 122 abdominal images acquired with a Acuson 128 XP (Acuson Inc., Moun- tain View, CA, USA) ultrasound machine.

This project will make the consumers actually see the effect of high and low power system in their consumption of energy. When the power factor is very low, the may be able to see the effect and reach out to make the operation system change as needed. They can increase the power factor by using the automatic power factor compensation which use capacitor and microcontroller as the main components. Thus, this will help in improving the power factor of a system. Plus, the current demand on energy is increasing day by day and the industries growth are inclining. Plus, according to Ministry of Health Malaysia (MoH), medical industries had been tremendously grow for the past decades, 8% to 10% annually. But on the other hand, the energy sources are depleting due to increase in population.

DOI: 10.4236/gep.2018.65021 251 Journal of Geoscience and Environment Protection at the top of the monitoring pile, i.e. , the total station is placed at the top of the reference pile to measure the relative elevation of the top of the monitoring pile at different time points. The displacement value of the monitoring point can then be obtained by calculating the elevation difference (see document [3] for the specific working principle). The relative elevation of the top of the monitor- ing pile was measured at two time points, December 13 of the installation year and June 18 of the following year. The calculation results show that the elevation of monitoring point #A rose by 0.73 cm and that of monitoring point #B sunk by 33.84 cm. These results are close to the displacement values monitored by the automatic monitoring device (monitoring point #A rose by 1.92 cm and moni- toring point #B sunk by 29.86 cm, as shown in Figure 3). The comparison is shown in Table 1. Thus, the automatic monitoring device can effectively indi- cate the change in the vertical displacement of the pipe.
