Abstract: Divulgation d'un dispositif électrique pour la conversion de molécules d'un certain poids moléculaire en molécules d'un autre poids moléculaire. On utilise un réacteur contenant une série de dynodes, chacune d'elles possédant plusieurs ouvertures. On produit un champ électrique en appliquant de l'extérieur une tension entre les dynodes. Lors du fonctionnement, des électrons et des ions frappent les surfaces intérieures des ouvertures des dynodes, ionisant les molécules adsorbées à la surface. Celles-ci sont désorbées sous l'impact, puis accélérées par le champ électrique vers un autre endroit sur la surface de la dynode, où elles se combinent à des molécules adsorbées pour former une variété de nouvelles molécules plus lourdes ou plus légères. Certains des ions produits subissent plusieurs déplacements et atteignent une extrémité du dispositif, où ils peuvent être pompés sélectivement. L'ionisation ayant lieu dans le dispositif, contrôlée par l'impact des électrons ou des ions, peut aussi conduire à des réactions entre plusieurs espèces moléculaires qui seraient improbables ou impossibles dans des conditions normales d'équilibre chimique ou en présence de catalyseurs courants.

Abstract: The present invention presents an apparatus and method for recovering symbols in a data packet (101) transmitted to a re-ceiver from a remote signal source (204) in a time-varying channel using multiple sampling points.  In a digital cellular radiotele-phone TDMA system, the receiver (202) performs a complex correlation on the desired slot sync word (DSSW) and the  coded di-gital verification color code (CDVCC) in the data packet (101), and on the adjacent slot sync word (ASSW) in an adjacent data packet (102) to produce a first, second and third optimum sampling point, respectively.  The data packet (101) is divided into four regions (A, B, C and D). The symbols in each region (A, B, C and D) are serially recovered using one or more of the multiple sampling points depending on the quality of the sampling point adjacent to each region (A, B, C and D).

Title: Current limiting solenoid driver

Granted: 2000-07-25
Abstract: CURRENT LIMITING SOLENOID DRIVER                ABSTRACT OF THE DISCLOSURE           A solenoid driver (28, 114, 151) applies an actuation current to a solenoid (14) for a predetermined period  and a  lower holding  current thereafter.   A switching device  (34,  116,  152)  pulses the applied current within upper and lower limits to maintain the actuation and holding current amplitudes, the pulses being  integrated  by  solenoid  inductance  into  a substantially steady-state current.  A multiprocessing unit (18) determines the amplitudes of solenoid current. A signal representative of desired current amplitudes is compared  with  a  signal  representative  of  measured solenoid current,  and a signal representative of the difference therebetween is used to control the switching device  (34,  116,  152).   Voltage developed across a resistor (36) in series with the solenoid (14) is input to a differential amplifier (40) having connected to its output a peak detector (42) that mimics the decay rate of   current   in  the   solenoid   (14),   the  signal representative  of  measured  solenoid  current  being obtained from the peak detector (42).  Power dissipation by the solenoid driver (28, 114, 151) is minimal, and the latter is capable of withstanding a continuous short to a source of electric current.  The output of the peak detector (42) is monitored by the microprocessing unit (18) for the detection and logging of faults.
