Abstract: Disclosed is a method for making a low-k, flame-retardant, bi-functional benzoxazine. The method includes the steps of dissolving phosphoric diamine with various functional groups, phenolic adamantane and paraformaldehyde in a solvent at 72° C. to 88° C. for 7 to 9 hours, and cooling and introducing the solution in n-hexane to separate the low-k, flame-retardant, phosphoric, bi-functional benzoxazine.

Abstract: An interactive intellectual robotic toy and control method of the same includes a main processor. At least one memory unit connects the main processor for storing motion data and sound data. A control module respectively connects the main processor and a driver module, and the driver module further connects motors. The control module receives the motion data stored in the memory unit under control of the main processor. An audio handling module connects the main processor and a speaker, the audio handling unit receives the sound data stored in the memory unit under control of the main processor. A USB module connects the main processor for renewing the data stored in the memory unit. A RFID module has a reading module connecting the main processor, a first RF antenna connecting the reading module and identification modules, each identification module has a design, a tag with an electronic code corresponding to the design, and a second RF antenna.

Abstract: A mobile electronic device includes a display module and a location module which is separable from the display module. The mobile electronic device utilizes a stylus and ultrasonic transducers arranged in the location module and the stylus to locate the stylus. The display module can be a bi-stable display module having at least one input communication module transmitting the location signal of the stylus to the location module. The location module has at least one output communication unit for disposing the location signal and then displaying the script on the display module. The output communication unit of the location module can be wireless communication unit applying GPRS, or EDGE, or 3G communication treaty, so the location module can communicate with the mobile station and become a mobile communication device.

Abstract: The present invention discloses an integrated dipole antenna and down converter apparatus. The integrated dipole antenna and down converter apparatus includes a dipole antenna for receiving microwave signals therein. The integrated dipole antenna and down converter apparatus further includes a down converter for receiving processed signals of the microwave signals from the dipole antenna for converting the processed signals to signals of lower frequency. The down converter includes main plate for supporting a tunable mechanical filter. The down converter further includes a tunable semi-mechanical filter supported on the plate. The semi-mechanical filter includes an upper circuit assembly and an identically symmetrical lower circuit assembly for canceling electromagnetic waves transmitting in the upper and lower circuit assemblies and the main plate whereby signal filtering efficiency is improved by reducing signal dissipation in the upper and lower circuit assemblies.
