Abstract: A Doppler control circuit for a CW or pulse Doppler radar system for monitoring not only the phase shift between echo signals from several targets but also the amplitude difference between the several targets and to further tune the radar to a particular target among one or more targets from which echo signals return. The control circuit can be used in state of the art CW or pulse Doppler type radar systems. In a further system, a continuously generated radar signal is repeatedly transmitted at different frequencies in time division fashion to define a succession of transmit and receive frames. The receive frames are divided into a plurality of time interval windows with selected windows being used to detect received signals at the different frequencies. The remaining windows can be used for subsystems of the radar system. The rate of phase shift of received signals at a reference frequency is used to determine closing rate (positive or negative) while the phase shift difference between received signals at two frequencies is used to determine range and target direction. In yet a further system, a special circuit is provided for conditioning selected portions of the Doppler frequency spectrum to attenuate or de-emphasize portions of the echo signal corresponding to selected targets in the radar system environment, such as rain or stationary wayside objects, in order to give such echo signals less weight in determining roadway hazards.

Abstract: The device includes a flat and elongate capacitor (4) with a piezoelectric dielectric (2) placed between two electrodes (1, 3). This capacitor is fixed to a barrier-forming surface, such as a window, a cabinet or glazing delimiting a site to be protected. It is linked to an electrometric amplifier, the signals from which are transmitted to an electronic alarm unit. Upon blows or mechanical forces being exerted on the window for the purposes of breaking in, the capacitor delivers electrical signals able to trigger an alarm from a certain threshold. The capacitor and the amplifier may also be arranged and set up to trigger an alarm upon alterations in the electric field due to the movement of a dielectric within the site. <IMAGE>

Abstract: Various optical functions are generated in accordance with the present invention of a novel broadly tunable monolithic wavelength selective coupler which can be integrated with a gain medium to form a broadly tunable laser. The tunable wavelength selective coupler supports a pair of asynchronous waveguides (16,18), an upper waveguide and a lower waveguide, in combination with a phase match course grating for coupling optical energy between said waveguides. One end of the lower waveguide terminates at an output facet. The corresponding end of the upper waveguide terminates in an optical signal absorbing medium (14). The other end of the lower waveguide is terminated to prevent optical energy from entering the waveguide; and, the corresponding end of the upper waveguide terminates at an input facet. The combination of a gain section and the monolithically tunable wavelength selective coupler forms a broadly tunable laser which is an important source of optical energy for a number of applications such as wavelength division multiplexed networks and switching systems. The laser frequency is determined by that wavelength λo which satisfies the forward coupling phase match condition, λg = Λ|N₂ - N₁| of the coupler where Λ is the coarse gating period and N₁,N₂ are the effective indices of the two waveguides. Wavelengths which are not coupled from the upper waveguide to the lower waveguide are attenuated in the optical signal absorbing means. Tuning of the laser wavelength is achieved by either injecting current into or applying a reverse bias voltage to the upper waveguide to decrease or increase its index respectively and change the coupled wavelength.

Abstract: A method for forming contact vias (34,36) in a integrated circuit (10) which do not have planarizing material nearby. After a first insulating layer (16) is deposited over the integrated circuit, a planarizing layer (18) is deposited over the first insulating layer. The planarizing layer (18) is etched back and portions of the planarizing layer (18) may remain in the lower topographical regions of the first insulating layer (16) to planarize the surface of the integrated circuit. A first masking layer (20) is then formed over the surface of the integrated circuit (10). The openings (22,24) created in the first masking layer have a size which is greater than the size of the contact vias to be formed. The first insulating layer (16) is partially etched into so that portions of the planarizing layer (18) near the locations of the contact vias (22,24) are removed. The first masking layer (20) is then removed, and a second insulating layer (26) is deposited over the integrated circuit (10). A second masking layer (28) having openings (30,32) which define the locations of the contact vias (34,36) to be created is then formed over the second insulating layer (26). The size of the openings (30,32) in the second masking layer (28) are smaller than the size of the openings (22,24) in the first masking layer (20). The contact vias (34,36) are then formed through the first and second insulating layers (26,18).

Abstract: The electrically driven dispensing apparatus has two electric motors (1, 26), one electric motor (1) with a first gearing (2) with a larger reduction ratio acting on the drive spindle (70) to rotate the latter in the feed direction and the other electric motor (26) with a gearing (27) with a smaller reduction ratio acting on the drive spindle (70) in the other direction to draw the drive spindle (70) back on load-relief and, on drawback of the feedbar(s) (15), to rotate it back for the exchange of the supply cylinders. Between the first drive (1, 2) and the drive spindle (70) one coupling element (3), and between the second drive (26, 27) and the drive spindle (70) two coupling elements (97, 102), are arranged and joined to one another via a pivot lever (82) in such a manner that all coupling elements can be switched over only during switchover from the feed position into the draw-back position and back again. Such an arrangement provides an effective load-relief on switch-off of the apparatus, which prevents post-flowing of material from the supply cylinders (cartridges) and makes possible relatively simple construction of the entire apparatus. <IMAGE>
