  • Patent number: 6384589
    Abstract: Reference frequency spur cancellation in a synthesized measurement receiver is achieved by determining for any given frequency to which the receiver is tuned a list of integer multipliers of the reference frequency that produce spurious signals in the receiver's passband. For those values the amplitude and phase for each spurious signal is determined in the digital domain and subtracted from the digital signal from the receiver. The reference frequency is then offset slightly and the measurement repeated. The maximum values between each measurement are combined to produce a measurement for the input signal without spurious signals.

  • Patent number: 6375328
    Abstract: Liquid crystal modulation elements are arranged so that light outgoing surfaces thereof face light incident surfaces of a color synthesizing prism. Transparent plates are bonded to the light outgoing surfaces of the liquid crystal modulation elements. For this reason, adhesion of dust to the light outgoing surfaces of the liquid crystal modulation elements can be prevented. Further, it is possible to prevent light reflection at the interface surface between the light outgoing surfaces and air due to the difference in refractive index therebetween. This allows a high-quality image to be projected without deteriorating the switching characteristic of the liquid crystal modulation elements while preventing dust from adhering to the light outgoing surfaces of the liquid crystal modulation elements.

  • Patent number: 6369583
    Abstract: The invention relates to a method for determining the spacing or distance of two reference points which are movable between a lower spacing limit and an upper spacing limit. The method is especially for determining the spacing of a vehicle body of a motor vehicle relative to a fixed reference point. The spacings are determined with the aid of a sensor and this sensor is attached as close as possible to a defined position. Thereafter, an offset is determined from the signal, which is indicated by the sensor, and from the signal, which a sensor would indicate if located in the defined position. For the spacing measurement, this offset is added to the signal, which is indicated by the sensor, and the spacing of the two reference points is determined from the summation signal which results in this way. With the method, it is achieved that an imprecisely installed sensor can be calibrated to a precisely installed sensor.

  • Patent number: 6328447
    Abstract: As a polarization beam separating device constituting a projection device, a thin-film multilayer film (reflective polarizer) is used. The thin-film multilayer film is composed of a plurality of alternately stacked layers including layers having a refractive index in a predetermined direction and a refractive index in a direction perpendicular to the predetermined direction, the refractive indices being almost equal to each other, and layers having different refractive indices in a predetermined direction and in a direction perpendicular to the predetermined direction. The use of the reflective polarizer makes it possible to reflect linearly polarized light polarized in a first direction and to transmit linearly polarized light polarized in a second direction, which is perpendicular to the first direction, with respect to light of almost all wavelengths in the visible region. As a result, the contrast of an image to be projected can be improved.
