Abstract: A non-common-ground bandpass filter circuit with electrostatic discharge (ESD) protection is disclosed. The non-common-ground bandpass filter circuit with ESD protection includes a non-common-ground plane, a dielectric substrate and a conductor. The conductor is disposed above the non-common-ground plane. The dielectric substrate is disposed between the conductor and the non-common-ground plane. The non-common-ground plane at least has a first ground region and a second ground region separated and insulated from each other. The first ground region corresponds to a first terminal of the conductor and the second ground region corresponds to a second terminal of the conductor. When an ESD event occurs on one of the first ground region and the second ground region, the other of the first ground region and the second ground region will not be damaged by the ESD event. The non-common-ground bandpass filter circuit also provides surge protection.

Abstract: A positioning and tracking system is disclosed. The positioning and tracking system includes positioning sensors disposed in a space, wherein the positioning sensors are all movable and all have functions of sensing distance, angle and time, and the positioning sensors communicate with each other to sense relative distances, relative angles and relative times between every two positioning sensors of the positioning sensors. when at least one of the positioning sensors moves in the space, the positioning sensors re-communicate with each other to instantly update the relative distances, the relative angles and the relative times between every two positioning sensors of the positioning sensors.

Abstract: Disclosed herein is a process for producing orchid seedlings by static liquid culture, in which a suitable amount of orchid seeds are suspended in a liquid medium suitable for the germination and growth of the orchid seeds to form a seed suspension; the seed suspension is then added into an empty culture container, so that the seed suspension within the culture container has a predetermined depth sufficient to enable each of the seeds to be suspended within the liquid medium while not causing said each seedling to an oxygen-deficient state; thereafter, the container is allowed to stand, such that the seeds suspended within the liquid medium germinate and grow into seedlings. The young seedlings thus obtained can be further cultivated by static liquid culture.

Abstract: A device for health and beauty care comprises an energy wave generator 1 consisting of a microprocessor, a signal generator, a filter, an attenuator, a gain amplifier, an exciter, a loop detector and a voltage display. The surface of the energy wave generator is provided with a plurality of sockets and knobs. The sockets are for connecting a conducting wire with a free end separated into a positive-polarity connector and a negative-polarity connector. The device for health and beauty care further comprises two connecting plates respectively connected to the positive-polarity and the negative-polarity connectors of the conducting wire. Each of the connecting plates further includes an insulting pad. To use the present invention, a person places his or her bare feet of on the connecting plate, and the massagist stands on the connecting plate barefooted, thereby forming a conducting medium and enhancing the massage effect by the electric energy wave.
