  • Publication number: 20050141476
    Abstract: Disclosed is an algorithm for dynamically changing an RTS threshold, which is a threshold for RTS-CTS frame exchange, depending on the traffic load in the BSS so as to maximize the MAC throughput of an IEEE 802.11 wireless LAN system. The present invention defines a new performance index based on the total time taken to transmit a frame and the time taken to successfully transmit a data frame. The RTS threshold is dynamically increased/decreased in a predefined range depending on the change in the new performance index.

  • Publication number: 20050118037
    Abstract: A hermetic compressor is constructed to easily cover a ground hole, thus preventing paint from flowing into the ground hole during a painting work. Into the ground hole is fitted a cap. The cap includes a head, a body, and a shoulder which are integrated with each other into a single structure. The head has a larger diameter than the ground hole. The body extends from the head, and has a similar diameter to the ground hole. The shoulder has a larger diameter than the ground hole, and is provided on a predetermined portion of the body to be spaced apart from the head by a thickness of the ground hole. When the cap is fitted into the ground hole, the head and the shoulder are respectively in close contact with portions around the ground hole. The shoulder has a side surface which is inclined at a predetermined angle with the body of the cap to form an inclined surface, thus allowing an upper end of the shoulder to be smoothly removed from the ground hole. The cap is made of rubber or a silicone.

  • Publication number: 20050094137
    Abstract: In a method for inspecting a defect in accordance with one aspect of the present invention, an object is divided into a plurality of regions. Reflectivity of each of the plurality of regions is obtained. Amplification ratio for each region is determined using the reflectivity. A light is irradiated onto the regions. A light reflected from a first region is amplified by a first amplification ratio that is determined for the first region. Moving the irradiated light from the first region to a second region is detected. A light reflected from the second region is amplified by a second amplification ratio that is determined for the second region. The amplified lights from the first region and the second region are analyzed to determine an existence of a defect on the object.

  • Publication number: 20050083539
    Abstract: An apparatus and method of measuring the thickness of a substrate. A first light is reflected from a standard sample having a known thickness. The light is concentrated through the light-focusing lens. The first light is converted into a first electrical signal by a detector responding to a light intensity of the concentrated first light. A second light is reflected from a substrate, and then is concentrated through the light-focusing lens. The second light is converted into a second electrical signal by the detector responding to a light intensity of the concentrated second light. An operating unit determines first and second peak values from the first and second electrical signals, respectively. The operating unit calculates the thickness of the substrate by using a standard distance corresponding to the first peak value, a moving distance of the substrate corresponding to the second peak value, and the known thickness of the standard sample.
