Abstract: A method of extracting proteins and peptides from nano pearl powder comprising the steps of preparing a solution containing uniformly dissolved nano pearl powder; rotating the solution to form a suspension; sifting the suspension; separating a first organic compound extract of pearl having a molecular weight more than a predetermined molecular weight and a second organic compound extract of pearl having a molecular weight less than the predetermined molecular weight from the sifted suspension respectively; and activating a first gel filter to obtain pearl proteins from the first organic compound extract of pearl, and activating a second gel filter to obtain pearl peptides from the second organic compound extract of pearl respectively.

Abstract: An emitter device includes a watch-shaped emitter member having one or more switch buttons to be actuated to generate signals, and a control device having an antenna to receive signals from the emitter member. A wireless device and a CPU are coupled to the antenna to process the signals from the wireless device, and a communication device is coupled to the CPU, to send signals out to various service centers via various network systems. The emitter device may be easily carried with the users, and may be used to ask help from the service centers or the other people.

Abstract: An emitter includes a housing for attaching to a user and for receiving a control circuit having one or more CPUs, a memory coupled to the CPU, a sensing circuit coupled to the CPU for sensing a voltage supplied to the CPU, an emitting circuit coupled to the CPU for being actuated by the CPU to emit a signal out. The housing includes two switches coupled to the CPU, and two further switches for information entering purposes. The emitting circuit may send out the signal by actuating the switches. The functions of the emitter may be tested with the switches.
