Golf shaft fitting calibration system

The calibration system was developed for golf shaft fitting to the club or blade. The system provided the best line and angle of golf shaft to fit into the club slot. This yielded the best controlling for the impact point between the club and the golf ball, including obtained the minimal swaying of golf shaft after the club hit to the ball. The proposed system was consisted of two components: the hardest line tuning and the best line calibration tool. The hardest line tuning was applied to search for the line that indicated the most strongest of the shaft, which contributed the minimal bend within the given certain forced pressure. The best line calibration tool was employed to determine the best angle for fitting the shaft to the golf club which reflected the minimal swaying while hitting to the ball. In this manner, the golfers could control the desired range and direction of the ball. © 2010 Published by Elsevier Ltd.

We propose a new system for image recorder server from IP camera. The system consists of 2 parts, Server and viewer. Server is software running on PC with ability to capture image from IP camera and save to disk like an image server. The second part is the viewer. A user be able to monitor and view the saved image on the server via a web-based application from everywhere with password protection. Live and history image can be show to user to check the status of area or investigate the history event. Further more. The server can connect to IP camera to collect image or connect a web cam directly to the server for cost reduction. Finally, the user can view the image by using browser on the PC or Windows mobile phone.

We propose a new system for SMS information display board. The system will display texts and icons of a message on the matrix LED. To sending a message to the system, A user have to send a message SMS on a mobile phone. It's mean, the user can be anywhere in the range of mobile signal to control the message on the display board. Furthermore, the user is able to control the pattern, speed and time duration of the display message. In additional, the user can set the time of the message to display on the system in advance or cancel it. The system provide the security by using password method to verified the authorize user only. Finally the system can apply to variety of usage with a lot of concurrent users and message scheduling application.

We propose a new system for wireless traffic light controller, it makes a traffic policeman easily and effective control a roadjunction with a wireless remote control. The system has two modes, Manual and Automatic. Manual mode provide the control oftraffic light to change manually by the traffic policeman, by just press the button related to the direction of the street to make agreen light signal. The remote will respond by checking the bearing of the pressed button on the remote using Hall effects sensorregarding to the position and direction of the remote. Then send the control signal to the traffic light controller board. Inautomatic mode, the traffic light controller board will change the light sequence according to the preset patterns and time delay,the traffic policeman be able to change the pattern at any time using the remote. The propose system help the policeman tocontrol the junction by himself and be able to change conditions of the traffic flow dynamically.

An atom/molecule/DNA probing and transportation using dynamic optical tweezers via a wavelength router
(2011-03-01)

A dark soliton pulse beam that has potential applications in the probing and transport of atoms or molecules as an optical tweezers is demonstrated. The trapped pulse beam is formed in the gap between a BP signal at 1500.00 nm and Stokes signal at 1500.09 nm, which has peak powers of -12 dBm. The generated beam is seen to be stable with no fluctuations over a test period of 10 min, which is important to ensure that the transported atom/molecule is not lost in the link media, therefore, the dynamic optical tweezers are now plausible. The theoretical background of the trapped atom/molecule is also analyzed and described in details. The atomic/molecular network via a wavelength router is also described. © 2010 Elsevier GmbH All rights reserved.

Dark soliton array generation: Theory and experiment

We present the fascinating results of dark soliton pulse array generation using the multilight sources via an optical multiplexer. The dark soliton array with different center wavelengths can be generated. The experimental setup was operated by using the brillouin-enhanced fiber laser scheme, whereas the experimental results of the dark soliton array are generated and achieved. In application, the dark soliton array can be used to form the molecules/atom trapping array, which can be used to form the molecules/atoms memory array for molecular computer and communication. Moreover, the transmission molecules/atoms can be secured by using the dark-bright soliton conversion behaviors. Results obtained have shown that the free spectrum range and the amplified power of 2.1 nm and 20 W of the bright soliton after dark-bright soliton conversion with wavelength center at 1.50 μm can be achieved, respectively. © 2010 Wiley Periodicals, Inc.

The new optical communication bandwidths (wavelength bands) using a Gaussian pulse propagating within a nonlinear microring resonator system is proposed. The Results obtained have shown that more available wavelength bands from the different center wavelengths can be generated, which can be used to form new dense wavelength division multiplexing bands. The novelty of the work is that the expansion of communication bands, especially, when the center wavelengths at 400 and 1,400 nm can be obtained by using a common laser pulse, whereas the amplified and non-dispersive light source can be formed. ©2010 IEEE.
