Inventor: MCCULLOUGH DOUGLAS A
IPC: H04N9/31
Filed: 1994-06-28
Abstract: A projection system for projecting computergraphic images onto a domed or spherical viewing surface (42). An intense beam of coherent light (10) is color and intensity modulated (28) and deflected (30) in a pair of cartesian axes prior to being projected through a wide angle lens array (40). Because the light beam is deflected before entering the wide angle lens array, greater angles of deflection are possible. The images are generated by rapidly changing the deflection of an intense spot of light which is projected onto the viewing surface at a rate above the viewer's flicker rate. This wide angle lens array may include a scan flattening lens array by which the image can be focussed onto a spatial image focal plane before it is projected through a wide angle lens.

Abstract: Un amplificateur d'énergie d'une clôture électrique est alimenté par un courant alternatif et comporte deux condensateurs de stockage (C¿1?, C¿2?), qui sont chargés par un circuit de charge (7) à une tension élevée. Ces condensateurs de stockage (C¿1?, C¿2?) sont déchargés par des enroulements primaires séparés (L¿1?, L¿2?) dans un transformateur (T) et l'enroulement secondaire (L¿3?) du transformateur est connecté à la clôture électrique. Les processus de décharge sont contrôlés par des circuits de décharge indépendants (R¿1?, Ty¿1?; Ty¿3? et Ty¿3? respectivement), de telle sorte que pour les charges légères un seul des condensateurs de stockage (C¿1?) est déchargé uniquement, et pour les charges importantes l'autre condensateur (C¿2?) est déchargé, et ce peu après le début de la décharge du premier condensateur et pendant le même cycle de décharge. Des circuits de détection (L¿2?, R¿8?, R¿9?, C¿3?; R¿10?, R¿11?, R¿12?, T¿4?, R¿13?) transmettent des signaux (PCHL; PPUL) à un microprocesseur (7) et ils représentent la charge sur le transformateur (T). Un des circuits de détection (L¿2?, R¿8?, R¿9?, C¿3?) comprend le deuxième enroulement primaire (L¿2?) et est utilisé pour mesurer les charges légères. Il détermine si le deuxième condensateur de stockage C¿2? doit être chargé et peut, dans certains cas, contrôler la tension de charge. Le deuxième circuit de détection (R¿10?, R¿11?, R¿12?, T¿4?, R¿13?) est connecté à une borne des condensateurs de mémorisation (C¿1?, C¿2?) et sert à mesurer les charges importantes. Il contrôle le moment du début de décharge du deuxième condensateur de stockage, et peut aussi, dans certains cas, contrôler la tension de charge. De cette manière, les impulsions fournies vont avoir une tension élevée et un énergie importante, ce qui assure une bonne sécurité.

Filed: 1996-06-27
Abstract: An accessory (10) for a wrench socket (12) is disclosed including a generally cylindrical magnet (32) secured to a generally cylindrical, nonmagnetic, compressible disk (26).  Specifically, the magnet (32) is received in a recess (46) formed in the disk (26) and secured to the disk (26) by a layer (60) of a size larger than and extending over the face (36) of the magnet (32) and integrally secured around its entire periphery to the face (44) of the disk (26).  The disk (26) snuggly fits within the well (14) and magnetically insulates the magnet (32) from the socket (12).  The magnet (32) has a size smaller than the well (14) and is generally concentric within the well (14), with an air space being created between the magnet (32) and the well (14) for magnetically insulating the magnet (32) from the socket (12) in the most preferred form.  The accessory (10) is removably insertable into the socket (12) of any design and model and without need for modification of the socket (12) and captures a fastener (16) slideably received in the well (14) of the socket (12) to magnetically hold the fastener (16) captive in the well (14) as the socket (12) is moved to the fastening location while not magnetizing the socket (12) or the fastener (16) sufficiently to be detrimentally magnetically attracted to metal adjacent to the fastening location.  In the most preferred form, the disk (26) further includes a second portion (54) of a size smaller than the first portion (52) for receipt in a connection passage (58) located intermediate the well (14) and the handle mounting end of the socket (12) and which is especially advantageous for sockets (12) having shallow depth wells (14).

Inventor: LAVIEVILLE JEAN-PAUL
IPC: H02M7/483
Filed: 1995-12-28
Abstract: The multilevel convertor includes capacitors (C1,C2...,Cn) for each of its cells. The capacitors have nominally charge voltages proportional to their row in the convertor. The convertor also includes control devices (BT, DA1...,DAn, pe2...,pen) designed to evaluate the voltage source (VECn) of the convertor. As soon as the voltage source (VECn) of the convertor is less than a set value, to suspend the nominal function of the convertor (sd) and to operate switches (T1,T`1,T2,T`2...,Tn,T`n) so that when the voltage (VE) of the voltage source (SE) has a value between zero and a least high nominal charge voltage, it charges all the capacitors of the convertor. When the voltage of the voltage source exceeds the least high nominal charge voltage, the capacitor (C1), nominally charged by this last voltage, is switched out of circuit. The voltage of the voltage source continues to charge the capacitors (C2...,Cn) demanding higher nominal charge voltages until the voltage exceeds that next least high voltage (C2), capacitor (C2) is then switched out, this continues until all the capacitors are charged to their nominal charge voltages. At the end of the complete charging sequence the control device restores the nominal operation of the convertor.

Title: A rate-controlled digital video editing method and system which controls bit allocation of a video encoder by varying quantization levels
Inventor: UNNO HIROAKI
IPC: H04N7/50
Filed: 1996-04-19
Abstract: A method and system for re-encoding frames of a digital video stream without changing the previously calculated bit length of the stream. A set of macroblocks at a time are re-encoded (292), the number of resulting bits is calculated (306, 368) and the deviation from an estimated number of bits is calculated (372), either set-by-set or cumulatively. Based on the accuracy (372), of the estimate (422) and the remaining number of sets of macroblocks (424) to re-encode, a correction factor (710) for the quantization level of the next set of macroblocks is chosen from a lookup table. The correction factor is added to the quantization level of the next set of macroblocks (712) and the results stored as the new quantization level of the set (706). This sequential process is done for all sets of macroblocks in the digital stream which are to be recorded according to changed image qualities (706, 708, 710, 712, 714).
