Abstract: A device for encouraging and guiding a spirometer user includes a housing, a main valve, a visual assembly, and a sound making assembly. The housing has a guiding channel, a first outlet channel, a second outlet channel, and an inlet channel. The main valve is disposed in a housing communicating with the guiding channel, the first outlet channel, the second outlet channel or the inlet channel and configured to regulate or control fluid flowing paths. The visual assembly includes a check valve in the second outlet channel, and at least one movable member. The sound making assembly includes a check valve and a sound maker. So, it can generate the visual and sound encouraging effects for learning how to use a spirometer correctly.

Abstract: An electronic device connects to a cloud server. The cloud server stores information of a first worker and a second worker. The second worker does work handover with the first worker. When it is time to do work handover by the second worker, the second worker uses the electronic device to touch the electronic device of the first worker. The information of the second worker of the electronic device is compared with the information of the second worker stored in the cloud server. When the information of the electronic device is the same as the information stored in the cloud server, a display device connected to the cloud server displays job contents stored in the cloud server.

Abstract: A MOS transistor cell is disclosed for a multiple cell MOS transistor, such as in an ESD protection circuit, output buffer, etc. The transistor cell has a regular n-sided polygonal geometry, wherein n.gtoreq.8. A drain region is provided in a substrate which occupies an area with n-sided polygonal shaped boundaries. Surrounding the drain, is a channel region which occupies an n-sided polygonal shaped area. Surrounding the channel region is a source region provided in the substrate which occupies an annular shaped area having n-sided polygonal boundaries.
