摘要:
A control device for the drive motor of a windscreen wiper device in a vehicle, especially a motor vehicle, comprising a control switch which can be activated by means of a manually actuated wiper switch and which automatically controls the drive motor in a switching stage of said wiper switch according to a rain sensor signal corresponding to a characteristic curve. The operating data for the drive motor varies according to the external effects of lighting, temperature, or speed parameters.

A control device operates a window wiper in a motor vehicle, and includes a switching device for the selection of several wiping functions, a sensor device for determining a wetting degree of a window, and an electronic analyzing system. The window wiper is capable of being operated, depending on the wiping function selected by the user, in a continuous wiping operation and/or in a single wiping operation. The electronic analyzing system, during a first wiping function, analyzes the determined wetting degree of the window and, depending on the determined wetting degree of the window, in a continuous wiping operation, sets a wiping frequency and/or, in a single wiping operation, activates a wiping cycle for the window wiper. The electronic analyzing system sets the wiping frequency of the window wiper in the continuous wiping operation during a second wiping function within a second wiping frequency band, and during a third wiping function, within a third wiping frequency band, and during the first wiping function, within a first wiping frequency band, depending on the analysis of the wetting degree of the window, an actual wiping frequency being set which is as optimal as possible. If, during the switching between the wiping functions, a change of the wiping frequency band is required, the actual wiping frequency, during a change from the second wiping frequency band to the third wiping frequency band is increased by a defined number "n" wiping cycles per minute or, during a change from the third wiping frequency band to the second wiping frequency band is reduced by a defined number "m" wiping cycles per minute.

An optical switch comprises a substrate, first and second optical waveguide, and first and second conducting elements. The first optical waveguide is coupled to the substrate. The first conducting element is coupled to the first optical waveguide. The second optical waveguide is coupled to the substrate. The second conducting element is coupled to the second optical waveguide. In operation, a first electrical bias applied between the first and second conducting elements causes the first optical waveguide to not optically couple to the second optical waveguide. Further in operation, a second electric bias applied between the first and second conducting elements causes the first optical waveguide to optically couple to the second optical waveguide.

A tunable, single-frequency, solid-state ring laser includes a solid-state laser material pumped by laser-diode light and at least one additional external piece which reflects the intra-cavity lasing light in a closed loop such that the plane of polarization is changed in an appropriate amount to compensate for magneto-optic change (Faraday rotation) of the plane of polarization, which occurs either inside the solid-state material or in one of the external pieces which traversed by the intra-cavity lasing beam. At least one of the external elements has the ability to change the optical path length of the intra-cavity lasing beam in order to tune the laser frequency by means of mechanical movement, electro-optic properties, magneto-optic properties, or some combination of the above properties.
摘要:
A laser having a combination of end and side pumping so as to produce high power pulsed output with little or no delay between side pump pulses and laser output pulses, with suppressed spiking due to gain switching, and with high modulation rates. An active medium, such as a solid state laser rod, in a resonant optical cavity is pumped by a first optical pump source directing radiant energy into an end of the active medium so as to encourage or establish lasing operation in a desired transverse cavity mode, such as the TEM.sub.00 mode. A second optical pump source directs additional radiant energy into a side of the active medium so as to amplify the intensity of the laser output in the desired mode. Typically, both pump sources are diode laser arrays, the first operating continuous wave or quasi-continuous wave, the second operating in high peak power pulses or being modulated at up to high data rates, that are determined by the cavity and active medium lifetimes and the ratio of the pumping power level to the threshold pumping level.
摘要:
A windshield wiper for motor cars with a wiper arm which terminates at its free end in a U-shaped hook, while a connecting piece articulated to a wiper blade and preferably consisting of plastics is slidable and anchorable between the members of the U. In order to ensure a play-free connection even in the longitudinal direction of the wiper arm and/or wiper blade, a fastening yoke, which is articulated to the connecting piece at a pivot axis thereof, in its closed position, engages externally and clamps around the U-shaped hook and tensions the connecting piece towards the wiper arm.

Retrieval of information and resources over the Internet is accelerated by automatically linking and synchronizing multiple device browsers in multiple tabs of device windows. The parallel tasks of access and execution, enables a client computerized device to search for information in parallel by activating multiple web sites' search engines, activating translation of web pages content by multiple translation engines at the same time and activating and deactivating a multiplicity of web resources in parallel. The method includes assigning multiple device browsers to multiple tabs in multiple device windows, thus enabling the efficient presentation of multiple web resources and enabling the user to speed the selection and switching between the accessed web resources displayed as tabs on device windows. Browsers linking topologies include; linking one to one, one to many, and many to many with unidirectional or two directional linking.

An all-weather housing for outdoor microwave radio nodes arranged in a network, each node capable of directing or receiving a beam of microwave energy in a selected direction, the housing including a shroud enclosing a transceiver, antenna, switches, and utilities. Each shroud has a radome projecting from the shroud in line of sight relation to other radomes in the network. A microwave radio transceiver is disposed within the shroud, operating on a scheduled transmission and reception basis in accordance with a schedule provided in a control channel amidst data. A ball-shaped microwave refractive lens is located adjacent to the radome, inside of the shroud, with a curved array of feed ports and switches, with the feed ports communicating microwave energy between the transceiver and the radome through the lens in multiple selected directions.
