Abstract: A disposable mask and suction catheter includes a mask having a front side and a back side, the back side being disposed in contact with a user's face during use. The disposable mask and suction catheter also includes a catheter tube having a first and a second end, the first end being removably attachable to a suction source for removing exhaled air and the second end being attached to the back side of the mask. The disposable mask and suction catheter helps to prevent fogging of glasses or other eyewear due to moist, exhaled air that escapes from behind the mask, and improves user comfort by constantly removing the warm, moist air behind and around the mask and drawing cool dry air into the mask.

Abstract: When data is simply input without being aware of describing a program language (e.g., COBOL or FORTRAN), the data input meaning is detected, and software for this data processing is automatically applied and prepared. Various types of worksheets corresponding to the business logic terms and data input positions are stored in a business data file. When an operation unit is operated and data is input to the data input position, the input data is stored as rule setting data. When application data corresponding to the rule setting data is input through the operation unit, a business logic applying section determines the use software in accordance with the corresponding business logic term.

Abstract: A method and apparatus for carrying out synchronous codivision multiple access (SCDMA) communication of multiple channels of digital data over a shared transmission media such as a cable television system coaxial cable, a fiber optic or copper conductor telephone link, terrestial microwave, satellite link, local or wide area network, wireless including cellur network or some combination of these media using suitable interface circuitry. The system includes modems at remote units and a central unit to receive time division multiplexed digital data arranged into timeslots or channels and uses orthogonal codes to encode each channel of multiple data and spread the energy of each channel data over a frame of data transmitted in the code domain. Spreading the data this way makes the system less susceptible to impulse noise.
