Abstract: A receiver includes a plurality of antennas; a switching device coupled to the antennas for selecting one of the antennas to receive transmitted signals; a demodulator coupled to the switching device for demodulating the transmitted signals to generate demodulated signals; and a control circuit coupled to the demodulator and the switching device, for counting a specific type of packets within the demodulated signals so as to accordingly control the switching device.

Abstract: An antenna device includes a pair of antennas and an isolating unit. The antennas have the same operating frequency. The isolating unit is disposed between the S antennas, and includes an LC circuit that has a resonant frequency, which is the same as the operating frequency of the antennas, thereby improving isolation between the antennas.

Abstract: The present invention discloses a prosthetic bone implant made of a hardened calcium phosphate cement having an apatitic phase as a major phase, which includes a dense cortical portion bearing the majority of load and a porous cancellous portion allowing a rapid blood/body fluid penetration and tissue ingrowth.

Abstract: The present invention discloses a method for making a porous calcium phosphate article including i) preparing a shaped article from a paste containing a calcium phosphate cement, a pore-forming powder and a setting liquid; ii) immersing the shaped article in an immersing liquid for a period of time so that the pore-forming powder is dissolved in the immersing liquid, creating pores in said shaped article; and iii) removing the resulting porous shaped article from the immersing liquid, wherein the resulting porous shaped article has an improved compressive strength. The porous shaped calcium phosphate article of the present invention may be used as a tissue-engineered scaffold, medical implant or a reinforcing constituent of a composite.

Abstract: The present invention discloses a method for making a molded calcium phosphate article including impregnating a rigid shaped article of calcium phosphate in an impregnating liquid for a period of time so that a compressive strength of the resulting impregnated article removed from the impregnating liquid is increased compared to that of the rigid shaped article. The molded calcium phosphate article made according to the present invention may be used as a medical implant or a reinforcing constituent of a composite.
