Abstract: A patrol-type preventive inspection system is provided for an inspection personnel to perform a patrol-type inspections upon a plurality of electromechanical devices located along a patrol path. In the patrol-type preventive inspection system, a portable inspection-device kit and a portable communication device are carried by the inspection personnel to a to-be-inspected position of a to-be-inspected electromechanical device out of the electromechanical devices along the patrol path, so as to perform a patrol-type inspection upon the to-be-inspected electromechanical device for obtaining at least one inspection data. When the inspection data complies with at least one preventive inspection standard, the portable communication device is provided for the inspection user to perform an interactive operation to generate a real rapid-screening result, further to generate a preliminary treatment suggestion, and to re-plan the patrol path.

Abstract: A planar array antenna structure includes a substrate, an array antenna, and a bottom ground portion. The substrate has a front surface and a rear surface. The array antenna is composed of a plurality of antenna units and disposed on the front surface of the substrate in a symmetrical and polygonal arrangement. A spaced slot is formed between every two antenna units. The bottom ground portion is polygonal and arranged on the rear surface of the substrate. The bottom ground portion has a plurality of included angles thereon, and one notch is formed between two included angles and the notches are correspondingly arranged to the spaced slots. Accordingly, the planar array antenna structure is used to generate high-gain radiation variations, effectively restrain the isolation between the radiators, and significantly increase overall performance of the antenna.

Abstract: A method for controlling an IP phone and an application program for the same are disclosed. The application program is installed in a computer for connecting the computer and a proximal IP phone via a wired or wireless network. A subscriber sends data and commands to the proximal IP phone via application programs in the computer for controlling the proximal IP phone. The computer establishes connection with a remote phone via an expanded function of the proximal IP phone controlled by the application program.

Abstract: A busy lamp field (BLF) system for remote telephones and a method for the same are disclosed. The busy lamp field system for remote telephones mainly has a plurality of switchboard systems and a XML server interconnected via the internet. Each switchboard system has a PBX and at least a telephone. Each telephone is connected to the XML server via internet and periodically uploads local phone status. The BLF key of each telephone is set to associate with a corresponding specific remote telephone by a subscriber of each telephone. Each telephone periodically retrieves the phone status of the corresponding remote telephone from the XML server displayed on the BLF key of the local telephone. Thus, a subscriber monitors status of a remote telephone and dials out via each PBX in addition to extension telephone of the local switchboard system.
