Abstract: Interleavers used in fading channel applications can be matched to a particular code being used. This matching can occur even in a particular transmission scheme such as TDMA. Matching both the interleaver and the code increases the separation between interdependent signal points and provides an improvement in error performance, without an increase in time delay over known interleaver design.

Abstract: A method is disclosed of simultaneously laminating circuitized dielectric layers to form a multilayer high performance circuit board and making interlevel electrical connections. The method selects two elements which will form a eutectic at one low temperature and will solidify to form an alloy which will only remelt at a second temperature higher than any required by any subsequent lamination. The joint is made using a transient liquid bonding technique and sufficient Au and Sn to result in a Au-Sn20wt% eutectic at the low temperature. Once solidified, the alloy formed remains solid throughout subsequent laminations. As a result, a composite, mulilayer, high performance circuit board is produced, electrically joined at selected lands by the solid alloy.

Abstract: A radiation measuring apparatus, in particular for measuring the luminescence, has a radiation detector and an injection device for adding a chemical substance into one or more sample containers; the injection device in this design terminates within the entry cross-section of the radiation to be detected. This makes it possible, virtually at the same time, to add a chemical substance and to measure, by means of the radiation detector, the photons emitted thereupon. The radiation detector in this design can be used in various ways: for example, the radiation to be detected can be fed to the radiation detector by means of a fibre optics bundle, or alternatively via an occulting disk, which provides a very compact arrangement. Special designs of the injection devices enable simple assembly and dismantling. <IMAGE>

Abstract: A method and system for embedding signatures within visual images in both digital representation and print or film. A signature is inseparably embedded within the visible image, the signature persisting through image transforms that include resizing as well as conversion to print or film and back to digital form. Signature points are selected from among the pixels of an original image. The pixel values of the signature points and surrounding pixels are adjusted by an amount detectable by a digital scanner. The adjusted signature points form a digital signature which is stored for future identification of subject images derived from the image. In one embodiment, a signature is embedded within an image by locating relative extrema in the continuous space of pixel values and selecting the signature points from among the extrema. Preferably, the signature is redundantly embedded in the image such that any of the redundant representations can be used to identify the signature. Identification of a subject image includes ensuring that the subject image is normalized with respect to the original image or the signed image. Preferably, the normalized subject image is compared with the stored digital signature.

Abstract: The present invention is made to reduce the effect of variation of pulses for driving a printer when recording image data and to improve the gray level representation of picture images to be printed. Data incoming through an image reading device are quantized and processed by two pixels by a gray level image processing circuit. The two-pixels' data are first discriminated by an edge discriminator (1) whether they represent an edge portion within the image or not. An object image, on which an operation for inter-pixel spacing shall be conducted, is selected according to the discrimination result. The arithmetic and logic portion (2) performs the above-mentioned operation by two pixels if the data are non-edge portion, while it performs correction for enhance if the data are an edge. This may eliminate effect of dots' displacement due to variation of drive in a printer and improve the quality, in particular, of a gray level image portion.

Title: Ultrasonic diagnosing apparatus
Inventor: GONDO MASAHIKO
IPC: G01S15/58
Filed: 1993-08-03
Abstract: Ultrasonic diagnosing apparatus includes an ultrasonic probe (1), an ultrasonic wave transmitting and receiving unit (4 to 9) for transmitting ultrasonic pulses (3) toward a living body and receiving ultrasonic waves reflected by the living body to produce an echo signal, and a signal processing circuit (10 to 22) for processing the echo signal such that a Doppler frequency representing a relative movement between the ultrasonic probe (1) and living tissues is detected and used to derive a value representing the velocity of a blood stream which is free from the influence of such relative movement. In a power spectrum distribution, said Doppler frequency can be detected as a peak frequency at which the magnitude of the power spectrum becomes maximum. In one embodiment of the ultrasonic diagnosing apparatus, the frequency axis of the power distribution is shifted such that said Doppler frequency becomes zero, and finally a Doppler frequency due to the blood stream is detected from a power spectrum component outside a cut-off frequency range. In another embodiment of the invention, a first Doppler frequency due to the blood stream is detected from a signal component which is obtained by MTI filters and auto-correlation circuits, a second Doppler frequency due to the relative movement between the ultrasonic probe and the living tissues is detected from a signal component which is obtained by the auto-correlation circuits, and then a velocity of the blood stream is detected from a difference between said first and second Doppler frequencies. Such ultrasonic diagnosing apparatus can enable a bloodstream of low velocity to be detected more accurately than in the prior art, and can advantageously be applied to an ultrasonic endoscope.
