Abstract:
A method for determining a user's body information in a mobile terminal includes determining whether a user touch is detected on a touch panel, which incorporates a Bio Micro Electric Mechanical System (MEMS) technology, and if so, determining the user's body information which in turn is transmitted to an upper node. Body information analysis results are received from the upper node and displayed subsequently. As a result, a mobile user has an advantage of managing his or her health via on line using a touch panel of a mobile terminal without visiting a hospital separately.

Various embodiments of a method for monitoring a machine condition are provided. An embodiment of the present invention provides a method of monitoring a machine condition, comprising the following steps: modeling a normal signal model performed by detecting a signal for monitoring condition of a normal machine and converting the detected signal to a normal signal model in time domain using a hidden Markov model (HMM) algorithm; calculating a probability value data of the monitoring signal at a subject machine performed by detecting a signal for monitoring condition of the subject machine in real-time and converting the detected signal to the probability value data relative to the normal state signal model using the HMM algorithm; and determining a section having deficiency where the probability value data of the monitoring signal at the subject machinery is not maintained constantly relative to the normal signal model.
Abstract:
A process for manufacturing a semiconductor device using a spacer as an etch mask for forming a fine pattern is described. The process includes forming a hard mask layer over a target layer that is desired to be etched. A sacrificial layer pattern is subsequently formed over the hard mask layer. Spacers are formed on the sidewalls of the sacrificial layer pattern. The protective layer is formed on the hard mask layer portions between the sacrificial patterns formed with the spacer. The sacrificial layer pattern and the protective layer are then later removed, respectively. The hard mask layer is etched using the spacer as an etching mask. After etching, the spacer is removed. Finally, the target layer is etched using the etched hard mask as an etching mask.
