This paper introduces the low-power design of a portable wireless ECG monitor which adopts MC35 GPRS module.At first,it presents the hardware and software system.Secondly,according to the principle of low-power design,it describes the low-power design methods from the aspects of hardware and software respectively.Finally,this paper discusses how to improve this power management system.In practice,this design efficiently reduces the power-consuming,and prolongs the working time of the monitor.

In order to study the effect of middle ear malformations on energy absorbance, we constructed a mechanical model that can simulate the energy absorbance of the human ear based on our previous human ear finite element model. The validation of this model was confirmed by two sets of experimental data. Based on this model, three common types of middle ear malformations,
Ear Ossicles ; Humans ; Incus ; Malleus
