An optical system capable of outputting hi-contrast images and multi-primary color or 3-dimensional images is provided. Light in primary colors RGB modulated in a first modulation optical system is transmitted through a relay lens 36 and further divided into a P-polarized light and an S-polarized light by a PS separation wire grid 37. The S-polarized light is transmitted through a wavelength spectral filter 39 to select red/green/blue light components R1, G1, B1 of 615, 515, 450 nm in wavelength, which are then modulated by a Y1 device 44. The P-polarized light is transmitted through a wavelength spectral filter 46 to select red/green/blue light components R2, G2, B2 of 650, 550, 475 nm in wavelength, which are then modulated by a Y2 device 51. The 3-primary color lights modulated by the Y1/Y2 devices 44, 51 are combined with each other at a PS composite wire grid 55 to project a synthetic light on a screen.

A germ-free liquid dispenser is disclosed. The dispenser includes a liquid container having a liquid outlet opening, a reservoir for receiving and reserving the liquid from the container, a holder for detachably holding the liquid container at its supply posture for orienting its outlet opening downward to allow the liquid within the container to flow down through the opening into the reservoir, a dispenser device for dispensing the liquid from the reservoir by allowing the liquid to flow down from the reservoir, and an antibacterial element having an antibacterial surface capable of killing germ through a physical contact therewith. The antibacterial element is disposed inside the reservoir in such a manner as to contact the liquid inside the reservoir while allowing the reservoir to dispense the liquid therefrom.
摘要:
A method and system for multiplexing additional audio information in the form of pulse code modulation (PCM) audio signals onto a television signal. The PCM audio signal is time multiplexed into scanning retrace intervals of the video signal. At a receiver, the bit error rate of the decoded PCM audio signal is compared with a threshold so as to switch the audio output from the PCM audio signal to a conventional FM demodulated audio signal when the bit error rate exceeds the predetermined threshold. In this way, the benefits of both PCM audio and FM audio can be obtained by utilizing the higher immunity of FM signals in low signal-to-noise ratio environments, while the high fidelity PCM audio signal is utilized when the signal-to-noise ratio environment is relatively high.

A mobile communication device equipped with a microphone, a receiver, a first circuit board which is provided with an antenna at the microphone side and a second circuit board opposing to the first circuit board, wherein the antenna has a first antenna part which is extended parallel to the edge of the first circuit board and a second antenna part which is extended from a free end of the first antenna part towards the second circuit board. The end of the second antenna part may also be extended in a direction parallel to the second circuit board so as to form a third antenna part. As a result, even if a user uses the device in a state with the receiver pressed against the ear, the antenna will not be affected by the user body and the antenna characteristics will not deteriorate.
