摘要:
A camera phone includes a phone stage for generating voice signals, a first image sensor for generating a first sensor output, a first fixed focal length wide angle lens for forming a first image of the scene on the first image sensor, a second image sensor for generating a second sensor output, and a second fixed focal length telephoto lens pointing in the same direction as the first lens and forming a second image of the same scene on the second image sensor. A control element selects either the first sensor output from the first image sensor or the second sensor output from the second image sensor. A processing section produces the output image signals from the selected sensor output, and a cellular stage processes the image and voice signals for transmission over a cellular network.

A low power radio transmitter includes an intermediate frequency stage, signal-to-pulse conversion module, and a power amplifier. The intermediate frequency stage up-converts the frequency of a base-band digital signal into an N-bit signal at the intermediate frequency. The signal-to-pulse conversion module converts the N-bit signal at the intermediate frequency into a pulse signal of M-bits at the radio frequency. As such, the signal-to-pulse conversion module is taking an N-bit signal (e.g., an 8-bit digital signal) and converting it into an M-bit pulse signal (e.g., a 1-bit pulse stream). Accordingly, the M-bit signal at the radio frequency is essentially a square-wave, which has a peak to average ratio of zero, is subsequently amplified by the power amplifier.

A windshield wiper drive device for driving a windshield wiper (11) in an alternating motion in a range of motion (17) between two turning point positions (A, C) includes a motor (1) for moving the windshield wiper (11), a detector (6) for detecting a time at which the windshield wiper (11) moves past a given position (A, C) in the range of motion (17), a control circuit (8) for reversing the direction of motion of the motor (1) at each turning point position (B, D), and an incremental transducer for detecting the distance traveled by the windshield wiper (11) from the given position (A, C). The control circuit (8) reverses the direction of motion of the motor (1) as soon as it is detected that the windshield wiper (11) has traveled a defined distance.

The invention concerns a mixture or polymer composite of a copolymer (CP) comprising between 70 and 99.9 wt % methylmethacrylate, between 0.1 and 5 wt % maleic acid anhydride and between 0 and 25 wt % further vinylically copolymerizable monomers which, apart from the vinyl function, have no further function groups, with a polymethacrylate-compatible plastics (VK) and a polymer (PN) which contains at least one terminal nucleophilic groups.
摘要:
The invention relates to liquid crystalline polymers which form exclusively nematic liquid crystalline phases. The liquid crystalline polymers are comprised of units of at least trinuclear liquid crystalline azo dye monomers M with lateral asymmetry.
