Taking Care

In this paper, the design of an automatic window is presented. The proposed window closes and opens automatically during and after a rainfall. The automatic system was developed with a focus on hospitals in order to allow medical staff and other supporting staff to concentrate on their primary responsibilities of taking care of patients. The system design includes a PIC16F877A microcontroller which gets activated when a moisture detector sensor sends a high logic signal to it. The microcontroller executes its embedded program by activating the stepper motor through a ULN2003 current-dependent integrated circuit (IC) chip resulting in stepwise control of the window. Hence, the window is automatically closed when rainfall is detected but opens and remains open when no rain is detected. We intend to extend our design to automatic opening and closing of the windows at others times in addition to during and after rainfall; for instance, window opening and closing every day at specific times in the morning and evening respectively.

A novel LabVIEW based system is designed to automatically sample hydrological samples in deep rivers. This paper is intended to describe the principles of the system design, the hardware component architecture and software design for the sampling operations. The designed system is capable of dynamically measuring the depth of water using a pressure sensor, as well as automatically taking hydrology samples by means of measuring cross-section 6 point method. The sampling operation tests showed the designed system has higher degree of automation, higher measurement precision, higher reliability and practicability.

The Cost

With the increase of integrated circuit switch rate and PCB density, signal integrity has become one of the problems must be concerned in high-speed PCB design. How to fully consider EMC (Electromagnetic compatibility) and take effective measures has been a key factor of a system design. Based on the consideration of EMC, the author put forward some aspects in designing high-speed PCB. The optimized PCB design rules have steady and credible performance, the development period is shortened and the cost is reduced. The conclusions drawn from the dissertation are helpful to the design of high-speed PCB.
