Abstract: An elastic shoe heel structure of a shoe includes a shoe heel and a shoe sole. The shoe heel is hollow or solid and has an upper edge soldered with a first end of a stepped elastic plate. The shoe heel has a stepped top surface corresponding in shape to the stepped elastic plate. An opposing second end of the stepped elastic plate has through holes for insertion of rivets to be connected to rivet holes of a rear section of the shoe sole. A gap is defined between the stepped elastic plate and the stepped top surface. When the user walks, a bottom of the shoe heel is contact with the ground and transfers a force from the shoe heel to the stepped elastic plate. The stepped elastic plate is compressed to absorb the force, providing a buffer effect.

Abstract: A method for quantifying a rapid immunochromatographic test includes the steps of: acquiring a digital image of a rapid immunochromatographic test with an image acquiring unit, acquiring at least one main characteristics of the digital image with a characteristics acquiring unit, calculating and quantifying the main characteristics of the digital image with a neural-network quantifying unit, and sending results of the quantification to an output unit.

Abstract: An integrated multi-purpose wireless network transceiver comprises a case holding a wireless network card or wireless network access device through wireless transmission to interface with the computer server at a client or access end, a flipping device on top, a holder for memo paper and a knob to support an upright pen holder. The flipping device comprises a preset board and a connected flipping cover. On top of the preset board, there is an electronic calculator module for numerical calculation. Below the electronic calculator module, an electronic clock and calendar, module are connected to set time, alarm and calendar. At the inner side of the flipping cover, there is a display available to show the formula and results for the electronic calculator, and the time and date for the electronic clock. This integrated design is provided to the multi-purpose wireless network transceiver for the present invention.
