  • Patent number: 10755320
    Abstract: A computer program product enables an advertisement audience dynamical detection circuit to conduct an advertisement audience quantity detecting operation. The advertisement audience quantity detecting operation includes: receiving a probe request frame transmitted from other wireless communication device; recording the arrival time of the probe request frame; inspecting the frame field configuration of the probe request frame; allocating the probe request to a corresponding data group according to the arrival time and frame field configuration of the probe request frame and a sequence control value in the header of the probe request frame while ensuring all probe request frames in the same data group have same frame field configuration; and calculating an estimated quantity of advertisement audiences passing through a specific location in a specific time period based on a total quantity of resulting data groups.

  • Publication number: 20180289569
    Abstract: A bed device has a bed body having a frame part and a mattress laid on the frame part, and an excreta treatment unit located below the mattress. The mattress has a through hole at a section corresponding to buttocks of a user. The excreta treatment unit has an excreta recovery unit attached to the through hole, an excreta storage unit configured to store excreta recovered at the excreta recovery unit, and a cleaning unit attached to the excreta recovery unit for jetting washing water upward via the through hole. The excreta recovery unit has a cup fitted to the through hole, a recovery pipe provided between the cup and the excreta storage unit, and a convex part extending upward from an edge of the cup to be inserted between the buttocks.

  • Publication number: 20060240671
    Abstract: A method for reducing outgassing pollution in a semiconductor process includes matching a pressure of a VCE with a pressure of a process chamber before reaction gas is injected into the process chamber, injecting the reaction gas into the process chamber, opening a partitioning door disposed between the VCE and the process chamber, and extracting from the VCE gas formed by a reaction between residual reaction gas on a wafer surface and gas in the VCE through an exhaust of the VCE.

  • Patent number: 6478932
    Abstract: A combination process of vacuum sputtering and wet coating produces a high conductivity and light attenuation anti-reflection coating on a substrate of a CRT surface. The coating includes five layers by vacuum sputtering and one layer on top of the coating by conventional wet process. The layers produced by vacuum sputtering provides high anti-reflection, low resistivity, and light-attenuation effect. The layer produced by wet process provides fingerprint proof effect.
