Abstract: In a fastener-driving tool comprising a housing structure defining an axis and a nosepiece extending from the housing structure, a primary actuating structure is movable between a tool-disabling position And a tool-enabling position, and a secondary actuating structure is coactive with the primary actuating structure for moving the primary actuating structure to the tool-enabling position when the secondary actuating structure is pressed firmly against a workpiece.  The primary actuating structure is biased to the tool-disabling position by a primary spring or springs.  The secondary actuating structure is biased away from the primary actuating structure by secondary springs.  When the secondary actuating structure is pressed firmly against a workpiece, the primary spring or springs exhibit a biasing force less than the biasing force exhibited by the secondary springs.  The secondary actuating structure may be also biased away from the housing structure by a tertiary spring.

Abstract: A Code Division Multiple Access (CDMA) communication system which contains a calling channel which is used to inform silent mobiles that they are being called. In the system, the calling channel is chosen to be the strongest overlapping signal so that it reaches mobiles which are located on the cells extreme boundaries. The interference other signals experience because they overlap with the calling channel may be avoided by having the mobiles first demodulate the calling channel signal and then substract it out before demodulating their own signal.

Abstract: An in-line gearshift  mechanism for use with a powershift transmission of an agricultural vehicle. The gearshift mechanism includes a shift lever assembly, a shifter plate and a switch plate each separated by a plurality of spacers and secured as an integral  unit  to  a  frame  portion  of  an  interior  of  the agricultural vehicle.  The shifter plate includes a plurality of in-line detent positions defining forward upshift,  forward, forward  downshift,  neutral,  reverse  downshift,  reverse  and reverse upshift detent positions at which the shift lever may be positioned.  The shift lever includes a gear encoder plate on which a plurality of switch activating elements are positioned.          As the shift lever is moved between the above-mentioned detent positions, the switch activating elements selectively actuate selected ones of a plurality of reed switches disposed on the switch plate.  The reed switches generate signals indicative of the position of the shift lever, which may then be used to inform an external controller of the position of the shift lever and thus the desired operation  (i.e.,  forward upshift,  shift to neutral, etc.).  In the preferred embodiment a neutral detection limit switch is also included which is actuated when the shift lever assembly is placed in the neutral position.  The preferred embodiment also includes a throttle lever for adjusting the speed of an engine of the agricultural vehicle.   A program further determines if forward downshifts or reverse downshifts are in fact desired by the operator as the shift lever assembly is moved through the forward downshift and reverse downshift positions.

Granted: 1998-11-03
Abstract: An optical waveguide circuit comprises a mode splitter and an input guide (1/4/6.1) and first and second output guides (6.2/2, 6.3/3), and a mode converter (5) incorporated in the input guide for converting a fraction of an optical signal (Ii), entering via the input waveguide, of a first propagation mode into a second propagation mode having mutually different order.  The mode converter (5) has a first waveguiding section (5.1) and a second waveguiding section (5.2), which adjoin each other via a single discontinuity (7).  The first and second sections (5.1 and 5.2) have propagation modalities, as a result of which, at the discontinuity, a coupling can take place between two propagation modes of different order, whereas the extent (x) of discontinuity determines the fraction of conversion for obtaining a desired splitting ratio inemitting signals (Io1, Io2).

Title: Apparatus and method for controlling the loop bandwidth of a phase locked loop
Inventor: GILLIG STEVEN FREDERICK
IPC: H03L7/183
Filed: 1994-11-21
Granted: 1999-08-10
Abstract: In a phase locked loop (PLL) (308), an edge proximity dectector (302) identifies a phase error, indicative of a difference between a phase of a reference frequency signal (115) and a phase of an output frequency signal (116 or 117), as either desirable or undesirable. When the phase error is identified as desirable, a counter (301) determines a rate of change of the phase error over a first predetermined time period (412) to provide an indication of frequency error (306) between the frequency of the reference frequency signal (206) and the frequency of the output frequency signal (116 or 117); and a loop bandwidth adjuster (310) controls a transition between a first and a second loop bandwidth state of the PLL (308) responsive to the indication of the frequency error (306). When the phase error is identified as undesirable, the PLL (308) operates in the second loop bandwidth state. The present invention advantageously provides an accurate determination of when to vary the loop bandwidth of the PLL (308).

Abstract: L'invention concerne un procédé de traitement de semences. Ce procédé consiste à placer les semences au contact d'une première surface d'une membrane semi-perméable (2) comportant une première et une deuxième surfaces, la deuxième surface étant en contact direct avec une solution d'un potentiel osmotique prédéterminé (5). Les semences (6) attirent ainsi l'eau de la solution à travers la membrane (2), ce qui assure le déplacement constant ou périodique de la semence (6) et de la membrane semi-perméable (2) l'une par rapport à l'autre de telle sorte que la semence (6) est constamment ou périodiquement réorientée par rapport à la première surface. Cela assure le transfert de l'eau de manière homogène sensiblement sur la totalité de la surface de la semence. En ce qui concerne la prégermination de la semence, la pression osmotique et la période pendant laquelle les semences (6) sont maintenues en contact avec la membrane (2) sont suffisantes pour permettre la réalisation des processus métaboliques prégerminatifs dans les semences, jusqu'au stade précédant immédiatement l'apparition des radicelles. L'invention concerne également des procédés pour assurer la germination de la semence et induire une tolérance à la dessication. De préférence, la membrane semi-perméable (2) est prévue sous forme d'un tube de section circulaire ou polygonale qui tourne avec les semences (6) sur sa surface intérieure et la solution retenue entre sa surface extérieure et un autre corps auquel la membrane est scellée de manière étanche à l'eau.
