Abstract: Un analyseur, de préférence, reçoit une image imprimée adressée par une personne autorisée qui va servir à constituer un modèle ainsi qu'une image imprimée adressée par un candidat qui va servir à constituer de données de test. On compare les données de densité spectrale d'énergie (PSD) relatives du modèle à celles du candidat afin d'extraire une rotation et une distension que l'on utilise pour adapter le modèle ou le candidat en prévision d'une corrélation aux fins de la recherche d'une translation. Après application de la translation et raffinement de la rotation et de la distension, on utilise des valeurs de corrélation spatiale normalisée (NSCV) comme mesure de la qualité de la mise en correspondance, ces valeurs ayant également subi un seuillage permettant de décider d'un rejet ou d'une acceptation en cas de confrontation à des cas des plus manifestes. Lorsque le cas s'avère litigieux, on soumet le modèle ou le candidat dans leur ensemble à un réglage isomorphe aux fins d'une comparaison plus adéquate de leurs régions de chevauchement. Cette comparaison procède du même type que l'analyse PSD - mais pour des sous-régions multiples dans la région de chevauchement. Les valeurs de corrélation spatiale normalisée résultantes, qui sont moyennées pour donner lieu à une mesure de la qualité de la mise en correspondance, sont une nouvelle fois soumises à un seuillage aux fins de la décision finale à prendre dans les cas litigieux. On utilise l'écart de bruit des données de test par opposition à la position dans l'image pour pondérer l'importance de la comparaison au modèle dans chaque sous-région. Une mémoire permanente détient les instructions aux fins d'un fonctionnement automatisé.

Abstract: An energy beam threat dis-crimination system (110) adapted for use with laser beam energy (134). The system (110) includes a first detector (114) for detecting a first laser signal. A second detec-tor (112) detects a coherent laser signal. A timer circuit (124, 126) establishes a time interval between the detection of the first laser sig-nal and the detection of the coher-ent laser signal and provides an output (130) in response thereto.      A control circuit (128, 130) deter-mines, based on the output (130), if the first laser signal and/or the second laser signal is threatening.      In a specific embodiment, the first detector (114) provides an event detection flag (118) as an output in response to the detection of a first laser signal. The first detector (114) includes a high sensitivity laser light detector (142), a pre-amplifier (144), and an analog threshold circuit (146). The coherent detector (112) provides a coherent detection flag (116) as an output in response to the detection of the coherent laser signal. The timing circuit (124, 126) receives the event detection flag (118) as input and includes a digital clock circuit (124) that starts a timer (126) upon receipt of the event detection flag (118). A digital comparator circuit (128) is activated by the receipt of the coherent detection flag (116) which triggers a comparaison between the output (130) of the timer circuit (124, 126) and a time threshold (131) and provides a reflection signal output indicating if the laser signal is a potential threat or not. The time threshold (131) for determining that the laser signal is a potential threat is approximately 10 nanoseconds. Alternatively, the time threshold for determining that the laser signal is not a potential threat is approximately 40 microseconds.

Title: Electronic ballast with inrush current limiting
Inventor: TWARDZIK RENE
IPC: H02H9/00
Filed: 1999-07-06
Granted: 2008-09-02
Abstract: The electronic ballast has a rectifier arrangement (1) - which is fed by AC power supply voltage (U) - with active step-up converter (SW2), a storage capacitor (C2), a network for limiting an inrush current and two outputs, at which a stabilized DC voltage (U+) referred to housing ground as reference potential (Uref) is output. An inverter (2) is connected to the rectifier arrangement, a load circuit (3) with at least one fluorescent lamp (La1 and/or La2) being assigned to said inverter on the output side. The inverter has a converter network (T1/1, T1/2, C1, SW3, SW4), preferably designed as a push-pull circuit, with two bridge paths, which, in the steady-state operating condition, are alternatively switched through to the reference potential. In this case, the switching network for limiting the inrush current comprises a limiting resistor (Ri), which, in series with the storage capacitor (C2), is connected to reference potential. The junction point between the storage capacitor and the limiting resistor is coupled to the two bridge paths of the converter network in such a way that it is connected, in the steady-state condition of the inverter, via the latter to housing ground and the limiting resistor, which is thus effective only in the switch-on phase, is bridged.

Abstract: The invention relates to the inhibition of blood coagulation, especially during organ rejection, and in particular the inhibition of delayed vascular rejection. The invention provides anticoagulant proteins which are anchored to cell membranes. The anticoagulant function is preferably provided by heparin, antithrombin, hirudin, TFPI, tick anticoagulant peptide, or a snake venom factor. These anticoagulant proteins are preferably prevented from being constitutively expressed at the cell surface. In particular, expression at the cell surface is regulated according to cell activation, for instance by targeting the protein to a suitable secretory granule. Expression of these proteins renders cells, tissues and organs less vulnerable to rejection after transplantation (e.g. after xenotransplantation).

Title: Gas turbine aeroengine control system
Inventor: TSUZUKI SADACHIKA
IPC: F02C9/28
Filed: 2000-07-28
Granted: 2002-12-31
Abstract: In a control system for a gas turbine aero engine, the control system (ECU) is configured as a dual control system comprising two channels, Ch-A and Ch-B. Ch-A has two CPUs which conduct calculations separately based on the sensor outputs and one of the CPUs compares the results and if they coincide, the CPU sends the result of the other CPU to the FCU. If not, one of the CPUs determines that an abnormality arises in Ch-A and sends a result to Ch-B. Ch-B is constituted as a standby channel having only one CPU whose operation is monitored by a simple watchdog timer circuit. This enhances CPU failure detection with a relatively simple configuration, and eliminates the need for provision of an overspeed protector.

Granted: 2007-11-06
Abstract: There is disclosed a driving force control system for a four-wheel drive vehicle, which is capable of properly controlling the execution and cancellation of a lock mode in which the engagement forces of clutches for distributing a driving force to auxiliary drive wheels are made maximum, thereby reducing frequency and duration of the lock mode.  Further, there is disclosed a driving force control system for a four-wheel drive vehicle, which is capable of properly controlling the engagement forces of clutches for distributing a driving force of the main drive wheels to auxiliary drive wheels, thereby causing the clutches to efficiently operate without waste of power. When the vehicle is determined to be in a predetermined low vehicle speed condition, and at the same time, the shift lever of the transmission is detected to be in any of predetermined low-speed shift positions, execution of a lock mode is permitted in which the clutch engagement forces are controlled to lockable ones which can lock the main and auxiliary drive wheels to each other. When the driving force of the main drive wheels is lower than a predetermined value, the clutch engagement forces for the lock mode are limited to smaller ones than the lockable ones.
