摘要:
A system and method for processing postal work using Radio Frequency Identification (RFID) apparatus. With RFID applied to the postal work, the system includes a structure for managing postal devices used in postal registration center and postal delivery center such as embedded controllers for controlling monitors, audio alarms, alarm lamps and PDAs. The system also includes middleware for managing RFID readers and message repeater adopting Java Messaging Service (JMS) . This allows exchanging data received from the RFID reader by JMS transfer method, ensuring stable asynchronous exchange of information and effective monitoring of data transferred in an entire process of postal work. This also decreases the load of the middleware in a work environment where a large amount of data is received in a short period of time such as postal work process.

A multiple RFID reader system for controlling operations of multiple RFID readers is provided. To minimize radio interference between multiple RFID readers, when a new RFID reader connects to the system, the system calculates probabilities of radio interference between the new RFID reader and already connected RFID readers and creates a radio interference logical operation list using the calculated radio interference probabilities. When it has been requested that the new RFID reader be activated, the system compares the created radio interference logical operation list with a list of currently running RFID readers and decides whether or not to activate the new RFID reader based on the comparison.

Disclosed is an apparatus and method for preventing liquid refrigerant accumulation in an accumulator of an outdoor unit of an air conditioner. The method includes the steps of: determining a state of a compressor; if the compressor is in standby mode or off state, turning on a four-way valve; determining whether the state of the compressor in standby mode or off state continues longer than a predetermined amount of time; and if the state of the compressor continues longer than the predetermined amount of time, closing an expansion valve. Particularly, high-pressure refrigerant flows in the closed expansion valve while low-pressure refrigerant flows in a check valve through the four-way valve. The apparatus includes a suction pipe connected to spray oil of the accumulator to the compressor; a liquid recovery pipe with one end being connected to the suction pipe and the other end being connected to the accumulator; and a liquid recovery valve for controlling opening/closing of the liquid recovery pipe, in which a compressor of the air conditioner in cooling or heating mode is operated and a liquid recovery valve for controlling a liquid recovery pipe connected to the compressor and an accumulator is opened to reduce oil in the accumulator. According to the present invention, when the compressor is off, it is possible to prevent liquid refrigerant accumulation by changing refrigerant flow line to the accumulator and the refrigerant at the lower end of the accumulator can be recovered.

Provided is an air conditioner, particularly, an apparatus and method for controlling a super-heating degree in a heat pump system for preventing a liquid refrigerant from flowing into a compressor. The method includes: operating the heat pump system; receiving a present outdoor temperature, a pipe absorption temperature and a low pressure value of a compressor, respectively; computing a present absorption super-heating degree from a difference between the absorption temperature of the compressor and a saturated temperature at a low pressure side; and comparing an targeted absorption super-heating degree set in advance, with the computed present absorption super-heating degree according to the received outdoor temperature, and controlling the system so that the present absorption super-heating degree may follow the targeted absorption super-heating degree.
摘要:
The present invention relates to a photosensitive composition comprising a triazine-based photoactive compound containing oxime ester. The photosensitive composition according to the present invention has good sensitivity, retention rate, mechanical strength, heat resistance, chemical resistance and developing durability since it contains, as photopolymerization initiator, a compound having an oxime ester group and a triazine group in one molecule and thus effectively absorbs UV radiation. Therefore, the photosensitive composition according to the present invention is advantageous not only in curing of materials for color filters, resin black matrixes, column spacers, overcoats and passivation films of liquid crystal displays, but also in high temperature process characteristics.

A non-volatile storage system that performs programming and reading processes. The programming process includes coarse/fine programming and verify operations. Programming is verified by testing for two different threshold voltage levels while applying the same voltage level to the control gate of a memory cell by testing for current levels through the memory cells and adjusting the current levels tested for based on current temperature such that the difference between the two effective tested threshold voltage levels remains constant over temperature variation.

A color reproduction correcting system and method, and a video display device and method can reproduce original color by considering signal source and display device. Each signal source information and each display device information can be stored. The signal source and the display device, which are currently used (e.g., corrected), can be determined, for example, by a user selection. In one embodiment, the signal provided from a transmission side can be inverse gamma-corrected based on a corresponding signal source, and a colorimetric error of the inverse gamma-corrected signal is preferably corrected using corresponding signal source information and display device information. The corrected colorimetric error signal can be gamma-corrected based on a corresponding display device and then can be displayed on the corresponding display device.
