Abstract: Système compatible-ISA (100) comprenant sur son clavier (150) une touche de fonction supplémentaire. Celle-ci n'a pas de fonction définie pour les ordinateurs ordinaires utilisant la norme ISA. Lorsqu'une touche alphanumérique ou une touche de fonction ordinaire est activée sur le clavier, le système informatique (100) est interrompu au moyen de IRQ1 (154) et l'information de la touche est communiquée au système informatique (100) de façon que celui-ci (100) puisse répondre de façon ordinaire au moyen d'une routine de traitement d'interruption clavier ordinaire. Lorsque la touche de fonction supplémentaire et une touche alphanumérique sont activées en combinaison, une deuxième interruption différente de l'interruption IRQ1 est activée (p. ex. IRQ15 (222)). Le système informatique (100) répond à la deuxième interruption par une identification de la touche alphanumérique activée et en exécutant une fonction prédéterminée choisie. Le traitement de la deuxième interruption est exécuté par une routine d'interruption distincte à l'intérieur du système informatique (100) de sorte que les programmes résidents (TSR) ordinaires qui interceptent les entrées au clavier ordinaire ne peuvent pas intercepter directement une entrée au clavier provenant de la touche de fonction supplémentaire.

Granted: 1999-11-30
Abstract: Composition d'explosif comprenant un agent d'oxydation tel que du nitrate d'ammonium (NA), et un matériau combustible qui peut renfermer un mazout et comprenant également un combustible solide tel que des particules de caoutchouc ou des billes ou des flocons de polystyrène. On incorpore le combustible solide dans la composition pour obtenir une libération commandée d'énergie lors de la détonation de la composition d'explosif. On a remarqué qu'en remplaçant une partie ou la totalité des huiles combustibles liquides par un combustible solide à combustion lente, on ralentit le temps pendant lequel la pression monte lors de la détonation. On peut ainsi produire un explosif à faible énergie par onde de choc possédant une énergie par onde de choc réduite et une énergie lente accrue par rapport aux explosifs classiques, tels que les explosifs à huile combustible au nitrate d'ammonium (HCNA).

Title: Tissue equivalents
Inventor: DAVIES ALBAN
IPC: A61F2/06
Filed: 1994-03-29
Granted: 2002-10-15
Abstract: A method of forming a tissue equivalent is described. A length of polyester tube is threaded over a mandrel (H) and attached at either end by clips at A and D. A block (F) is then screwed into place. The polyester is then pre-soaked by injecting through Tap (2) an acidified collagen solution for approximately one hour. After a suitable period of time the excess solution is aspirated off. Following this stage, a second, alkaline solution is injected into the apparatus which contains smooth muscle cells (SMC). Thus, neutralisation of the collagen impregnated within the fabric of the tube occurs leading to spontaneous fibrillogenesis within the interstices of the cloth, eliminating the risk of delamination. The apparatus is then incubated. The collagen contracts down onto the fabric tube and the cell-impregnated gel becomes incorporated into the presoaked collagen. The pre-impregnated collagen and the collagen provided in the aqueous mixture contract down as one into a coherent whole with the SMC. The tissue equivalent is then lined with endothelial cells and the apparatus again incubated and fed at increasing intraluminal pressures applied either statically or dynamically.  This is believed to cause the vessel to become preconditioned to the pressure it will work under as an implant. This allows organisation of the basement membrane which in turn promotes EC attachment and theoretically prevents smooth muscle cell hyperplasia.

Abstract: A transmission power control method of a spread-spectrum communication system which determines transmission power in accordance with a transmission power control bit.  The transmission power control bit is extracted at a base station from a signal sequence obtained by receiving a signal transmitted from a mobile station, and by despreading and demodulating the received signal.  When the same value of the transmission power control bit is consecutively received, the transmission power of the base station is controlled in accordance with transmission power control quantities which are predetermined in accordance with the consecutive number of receptions of the same value of the transmission power control bit.  This is because the consecutive receptions of the same value of the transmission power control bit suggests that the received power of the other party (the mobile station in this case) changes greatly.  Thus, an amount of an increment or a decrement in the transmission power is increased with the duration of the consecutive receptions.  This makes it possible for the transmission power control to follow sudden changes in propagation paths.

Abstract: In a focal controller of a camera, two brightness components in different frequency bands are obtained by two band pass filters from a video signal obtained by image pickup.  Integral values a and b of the respective brightness components are detected by integrating circuits.  When both a ratio a/b and a value a calculated by an arithmetic circuit are increased, a CPU judges this increase as an unfocusing position of a focusing lens.  In contrast to this, when an increasing degree of the ratio a/b is decreased or tends to be decreased, the CPU judges this decrease as a position near a focusing position of the focusing lens.  Thus, the driving speed of a focusing motor is set to a high speed in the unfocusing position and is set to a low speed in the position near the focusing position.  For example, a microcomputer obtains a focal evaluation value at an interval of three fields (k+2 after k-1) in the vicinity of a focusing position and compares this focal evaluation value with reference data.

Granted: 2001-01-02
Abstract: Electrostatic spray coating system which accurately determines the actual value of a high voltage present on at least one high voltage electrode as coating material is electrostatically charge. A control or input voltage is measured on the input of a voltage transformer and multiplier circuit and is multiplied by the voltage multiplication factor of the voltage transformer and multiplier circuit, thereby calculating the theoretical or no load value of the voltage on the high voltage electrode. This theoretical value deviates from the actual value of the electrode voltage by the amount of the internal voltage drop across the voltage transformer and multiplier circuit when a current flows in it. The internal voltage drop is determined as a function of the electrode current and is subtracted from the theoretical value in order to generate a signal voltage corresponding to the actual value of the electrode high voltage. The signal voltage is subtracted from a desired value voltage in order to generate a regulating differential voltage for a controller which, in response thereto, regulates the electrode voltage and available power.

Granted: 2004-08-24
Abstract: Block or plug implants (11, 30) provide weight bearing support for adjacent vertebrae in a vertebral column while allowing sufficient area between and beside the plugs for packing of autologous bone graft (22) to allow bony healing and fusion. The plugs have a laterally directed slot (21) to allow ingrowth of blood supply from the side and to allow locking the permanent device in place with living bone. The plugs have a patterned surface (19) to grip the vertebrae.  Plugs (30) used for fusion in the L4-5 and L5-S1 levels are wedge shaped to reproduce the normal shape of these discs, which are higher anteriorly than posteriorly.  The height of the plugs is greater than the width.  The plugs are bottomed in the channels (15) on cortex bone and bone ingrowth and fusion is facilitated by packing a patent's own graft into the center of the plug and beside and between the two adjacent plugs.
