Patent EP-0319923-A2 (EP)
Inventor: HUNG YAU Y
IPC: G01L1/24
Filed: 1988-12-06
Abstract: A test object (13) is analyzed electronically, i.e. without the use of photographic film. The invention generates a pair of laterally-dis­placed images of the object (13) which interfere with each other to pro­duce a pattern that can be recorded without a high-resolution detector. The object (13) is illuminated with at least partially coherent light. Reflected light (25, 27) from the object (13) is directed through a bi­refringent material (15), a lens system (17), a polarizer (19), and then to an image detector (21), such as a video camera. The birefringent ma­terial (15) causes non-parallel beams originating from a unique pair of points (29, 31) on the object to become nearly parallel, and orthogonally polarized. The polarizer (19) modifies the polarization of the parallel beams so that they will interfere with each other. Because the interfer­ing light beams are nearly parallel, the spatial frequency of the inter­ference pattern is sufficiently low that the pattern can be recorded by a low-resolution detector, such as a video camera. Interference patterns due to the superposition of two laterally-displaced images of the same object (13) are recorded while the object is in an undeformed and a de­formed state. A computer (23) compares these interference patterns and produces a resultant pattern which depicts the deformation of the test object (13). Because photographic film is not needed, the invention can analyze objects very rapidly. Also, since the interference pattern is derived from pairs of distinct points on tDe object (13), the invention directly provides information on strain.

Abstract: An image suppression harmonic frequency converter capable of operating in any microwave range (up to and including the Ka range) is described. 
     Frequency conversion is obtained by making use of a local frequency (flo) which is half that of a conventional converter. In particular, the radiofrequency reception signal is converted into an intermediate frequency signal with suppression of the converted image band. Similarly, the intermediate frequency signal (fi) to be transmitted is converted into a single side band radiofrequency transmission signal (fs). 
     The converter comprises two harmonic mixers (M1, M2), a first in quadrature radiofrequency hybrid coupler (HYB1), a second in quadrature intermediate frequency hybrid coupler (HYB2), two appropriate duplexer filters (FA, FB), two low-pass filters (FB1, FB2), two matching circuits (R1, R2), and two decoupling circuits (DCB1, DCB2).

Abstract: Described is a method for applying optically readable code markings (14) on the surface of bottles (10) made of plastic or glass by producing depressions in the surface by means of a laser (12) in such a way that the base of each code marking (14) is formed as a diffusing reflector. For automatically reading the code markings, a sensor (16) constructed from optical fibres having centrally arranged emission optical fibres and radially arranged receiving optical fibres is used. The sensor forms an angle of less than 90 DEG  with the bottle surface, so that light is reflected into the sensor only at points on the surface where code markings (14) are present. The code markings (14) are simple to apply and can be reliably read.

Abstract: This invention provides an ultrasonic transducer system which utilizes a reconfigurable delay line to perform a variety of processing functions. In particular, for a preferred embodiment, the delay line utilized to sum the outputs of transducer elements (16A-16N) is reconfigurable to provide serial processing of image scan lines while providing parallel processing of Doppler color flow scan lines. More particularly, the echo signals generated in response to the packet of color flow lines utilized to generate color flow information are applied in a predetermined way to two separate portions of the delay line, the portions of the delay line having different delay profiles, the resulting outputs being focused to slightly different points in the image and thus providing color flow packets for two separate points in response to the transmission of a single packet of color flow lines. This results in a substantial enhancement of the system frame rate. 
     Other possible applications of the reconfigurable delay line in an ultrasonic scanning system are also discussed, and a packet serializer (62) is disclosed which buffers, sequences, and preprocesses the received packet data.

Abstract: A rotary paint atomizing device (10) in the form of a bell (11) and a cover plate (12) which is releasably attached to the front centre of the bell (11). Paint fed along the axis of the device onto a conical projection (24) on the back surface of the cover plate (12) accelerates and flows outward in a radial direction. The cover plate surface (20) is curved so that as the paint flows outwardly, it also flows first forward and then back until it reaches radial slots (28) formed in a peripheral rim (27) on the cover plate (12) where the cover plate contacts an interior bell surface (30). Paint discharges from the slots (28) onto a conical interior bell surface and flows in wide, closely spaced ribbons which merge into a uniform, continuous thin sheet before it is discharged from the bell edge (32). As the paint discharges from the bell edge, the sheet produces extremely fine uniform ligaments which break up to produce fine, uniform small paint particles.
