  • Patent number: 5867129
    Abstract: An automobile windshield covered with a transparent electrically conducting layer, on which some hollowed spaces are provided in the form of slots. The length of these slots is a function of the wavelength of the microwave radiation. The microwave radiation, as used for transmission of information in portable telephone sets or remote surveillance systems of toll roads, for example, is absorbed by the conducting layer to again be retransmitted by the slots which act as antennas. In this manner, vehicle windshields which are provided with an electrically conducting layer which reflects the infrared can allow microwave radiation to pass through.

  • Patent number: 5747170
    Abstract: A bombardment-inhibiting bulletproof glass pane for automobiles, composed of a plurality of silicate glass sheets (16, 17, 18, 19), connected together by thermoplastic intermediate layers (20, 21, 22). The pane may also comprise a silicate glass sheet (16) having a high absorption action in the spectral range from 780 to 1,200 nm. This silicate glass sheet (16) or another of the glass sheets (17, 18, 19) constituting the bulletproof glass pane may be provided, on one of its surfaces, with a partially reflecting surface coating (23), which has a high reflection in the spectral range of 780 to 1,200 nm. The bulletproof glass pane has, in total, a total light transmittance of less than 15%, and preferably of less than 10% in the spectral range from 780 to 1,200 nm. Bulletproof glass panes constructed in this manner offer a high security during night travel, because they are non-transparent to infrared sighting devices and noctovisers (night viewing devices).

  • Patent number: 5445694
    Abstract: An electrically heated composite glass sheet including heating element wires deposited and fixed in place on the thermoplastic film connecting the individual glass sheets together so as to extend from the one film edge as far as the opposite film edge. The heating wires are connected in parallel with buses, which are arranged at a predetermined distance from the edge of the film. Directly adjacent to the buses, the sections of the wires which are arranged between the buses and the edge of the film are severed by moving two electrodes, which are connected with a power supply, into contact with the wires. The electric current heats the wires between the electrodes to their fusion temperature and thereby severs the wires.

  • Patent number: 5144459
    Abstract: A windshield (1) for motor vehicles provided with a reflecting arrangement (6) for making optical information or signals visible to the driver of the vehicle; said information or signals being made recognizable in the same field of view as is suitable for the observation of traffic and the road ahead by said driver. According to the invention, the reflecting arrangement (6) is a hologram with the characteristic of a mirror. The angle of reflection .alpha. of the holographic mirror is different from the angle of reflection .beta. of the surface of the glass upon which said hologram is mounted. As a result the rays R' reflected from the surface of the glass do not reach the eye (8) of the observer, whereas the rays R reflected from the holographic mirror do.

  • Patent number: 4985671
    Abstract: A reasonably priced power supply circuit for a motor vehicle with two different load voltages, viz. the normal vehicle supply system voltage and a voltage higher than this for operation of a window heating glazing with a thin-film heating resistor. A generator is designed for the higher voltage, which corresponds at least to the voltage required for operation of the window heating glazing. With the window heating glazing switched off, the voltage supplied by the generator is adjusted to the vehicle supply system voltage by a controller. With the window heating glazing switched on, the vehicle supply system voltage is derived from the higher voltage. To ensure a safe operating condition, a time switch for the temporary reduction of the exciter current for the generator during change-over of the load switch, a main timer for limitation of the heating time and a threshold voltage switch for limitation of the generator voltage are provided as additional monitoring elements.
