Our societies are currently facing the increase of aged in the population. More and more elderly people suffer from the Alzheimer's disease. In order to reduce the cost for caring these elders, to let these elders foster automatically, Smart Home (Intelligent Health home) is proposed as a recency solution. This paper presents that EpiTalk advisor system assists the cognitive impaired elder to complete the ADLs by curing at home. The common temporal problems of ADLs are solved, which are the sequential problem, the random problem, and the synchronisation problem.

The poly(4-hydroxybenzoate) (PHBA) oligomer was synthesized by using the monomer of 4-acetoxybenzoic acid (PABA), and its blends with poly(trimethylene terephthalate) (PTT) are prepared by melt-blending at 250oC in nitrogen. Their chemical structure characterization and crystal morphology were investigated by using the fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (1HNMR), and polarizing optical microscopy, respectively. The results suggest that PHBA oligomer with 3 polymerization degree was synthesized and it is a thermotropic liquid crystal with the nematic characteristics. When the blends crystallize from melt, because the rigid oriented PHBA molecules becomes the nucleating agents for PTT molecules’ crystallization, much transcrystalline layers formed in the blends, although the crystalline PTT/PHBA blends show spherulites morphology character without observing nematic LC phase.
