Title: Insulated conductor for very high tension and process for producing thereof

Patent CZ-399099-A3 (CZ)
Title: User unit and method of its use in wireless communication system
Inventor: ODENWALDER JOSEPH P
IPC: H04B7/26
Filed: 1998-05-13
Abstract: A set of individually gain adjusted subscriber channels (402, 404, 411, 415) are formed via the use of a set of orthogonal subchannel codes (Wc, Ws, Wf) having a small number of PN spreading chips per orthogonal waveform period. Data to be transmitted via one of the transmit channels is low code rate error correction encoded and sequence repeated before being modulated with one of the subchannel codes, gain adjusted, and summed with data modulated using the other subchannel codes. The resulting summed data (410, 420) is modulated using a user long code and a pseudorandom spreading code (PN code) and upconverted for transmission. The use of the short orthogonal codes provides interference suppression while still allowing extensive error correction coding and repetition for time diversity to overcome the Raleigh fading commonly experienced in terrestrial wireless systems. The set of sub-channel codes may comprise four Walsh codes, each orthogonal to the remaining codes of the set. The use of four sub-channels is preferred as it allows shorter orthogonal codes to be used, however, the use of a greater number of channels and therefore longer codes is acceptable. Preferably, pilot data is transmitted via a first one of the transmit channels and power control data transmitted via a second transmit channel. The length, or number of chips, in each channel code may be different to further reduce the peak-to-average transmit power for higher rate data transmission.

Date Oct. 24, 1996A method for processing PWM waves for a voltage inverter or a voltage-controlled rectifier, including at least one pair of switches, said inverter or rectifier being controlled by a modulator and a discriminator. According to the method, two set waves corrected according to the current direction in the load or the source are applied to the discriminator. The corrected set wave for the output current has a high level to which a delay is added during transition from the high level to the low level, and the corrected set wave for the input current has a low level to which a delay is added during transition from the low level to the high level. The high level is defined by the fact that the switch connected to the most positive load is closed while the switch connected to the most negative load is open, and the low level is defined by the reverse.

Title: Stabilized power feed with low impedance
IPC: H02M7/06
Filed: 1994-03-18
Granted: 1996-02-06
Abstract: In traditional direct current feeds, the transformer is only loaded during asmall section of its work cycle. The smoothing capacitators are loaded upduring each cycle in a spasmodic way by the diodes of the rectifier, which isthe cause behind the typical saw tooth shaped ripple voltage that is superpostulated on the direct voltage. As a consequence, most of the time it isonly the smoothing capacitators that are forming the actual feed, and itsquality will directly determine the quality of the feed. In addition, due tothe alternating conducting and blocking of the rectifier diodes, interruptingpulses and harmonics are created, both on the connected loads and on thealternating current net. The invention described here does not have thepreviously stated disadvantages. The capacitors (C1 through C4) are connectedto the secondary connections of a transformer or an alternating currentgenerator that is loaded during one half of a period by means of diodes (D1through D4), or are in a series with a secondary connection. This takes placealternately (for example with the pares C1/D1 and C2/D2) so that there iscontinuously a different pair per pool recharging and another pairdischarging power to the load.

Abstract: L'invention porte sur un procédé de reconstitution d'images en 2D et 3D d'objets à l'aide de projections d'images radiographiques d'objets et de techniques de reconstitution par itération. Le procédé porte plus spécifiquement sur une image de l'objet à corriger. A cet effet, on prend deux ou plus de deux profils d'absorbance des rayons X dans deux ou plus de deux directions différentes de projection. Ces profils sont comparés aux profils d'absorbance correspondants de l'objet passablement rempli d'agent de contraste pour rayons X, et sur la base de cette comparaison, l'image est corrigée à l'aide de techniques de reconstitution par itération. Avant chaque itération les pixels de l'image sont actualisés et si la valeur de l'absorbance d'un pixel passe au-dessous d'un niveau présélectionné, le pixel revient à zéro; sinon, le pixel est porté à la valeur d'absorbance correspondant à la concentration dans l'objet d'agent de contraste pour rayons X. L'itération cesse quand la différence entre les profils d'absorbance de l'image et de l'objet tombe au-dessous d'une valeur présélectionnée.
