  • Publication number: 20020175294
    Abstract: A light detecting and ranging system and method for detecting airborne agents in which the system includes a laser which provides laser pulses of at least two wavelengths, a transmitter which transmits the laser pulses, a receiver which receives both elastically backscattered signals from airborne agents and fluorescence signals from the airborne agents, a common telescope which both focuses a laser beam transmission of the laser pulse from the transmitter to a far field and receives the elastically backscattered signals and the fluorescence signals from the far field, a digital detection system having at least one of a backscatter optical detector which detects the elastically backscattered signals and a fluorescence optical detector which detects the fluorescence signals from the airborne agents.

  • Patent number: 6145822
    Abstract: Disposed is a supporting mount for a power plant such as an engine or a transmission. The power plant includes an inner pipe and an outer pipe, a vibration absorbing member interposed between the inner pipe and the outer pipe, a rolling restriction member connected to the inner pipe and which restricts the power plant from vibrating more than a predetermined amount with relation to a vehicle frame, first and second fluid chambers formed in the vibration absorbing member and which are filled with operating fluid, first and second fluid communicating passages communicating the first and second fluid chambers, a displacement reaction portion provided in the outer pipe and which reacts to substantial movement by the outer pipe by contact with the rolling restriction member, and a fluid passage adjusting portion which decreases a size of the second fluid communicating passage in direct proportion to the amount of rolling of the engine or transmission to which the displacement reaction portion responds.

  • Patent number: 5737077
    Abstract: A time resolved spectroscopy system and method are provided using digital processing techniques of a low power, continuous wave signal generated by a continuous wave light source, such as a cw laser. Time elapse is determined by measuring the time shift of the signal modulation sequence using the cross correlation of a return signal with the reference signal. The high resolution time delay is introduced at the start of each modulation cycle and the high resolution measurement is constructed by interlacing a data set based on the delay information. The high resolution TRS or fluorescence measurement is achieved by correlation calculation of the measured data and the reference code and deconvolving the autocorrelation function of the reference code.
