Abstract: A configurable logic array includes an array of configurable logic cells (R₁C₁, ... R₈C₈) arranged in columns and rows. A plurality of input/output cells are arranged around the perimeter of the array, and provide interfaces to input/output pads on the chip. A configurable interconnect structure includes vertical buses (VBUS1, ... VBUS9) between the columns of configurable logic cells, and horizontal buses (HBUS1, ... HBUS5) between the rows of configurable logic cells. Thus, each configurable logic cell in a subset of the array, has four adjacent buses in the interconnect structure. The configurable logic cells in this subset of the array include input structures, having programmable inputs connected to the buses on all four sides of the cell. Also, combinational logic connected to the input structure generates logic signals in response to the selected input signals. Finally, the configurable logic cells include output structures connected to the combinational logic, and having programmable outputs connected to the buses on all four sides of the cell.

Abstract: Tri- and tetra-substituted guanidines which exhibit a high binding affinity to phencyclidine (PCP) receptors and, more preferably, low affinity to the brain sigma receptors. These guanidine derivatives act as non-competitive inhibitors of glutamate induced responses of the NMDA receptor by acting as blockers for the ion channel of the NMDA receptor-ion channel complex. These compounds thus exert neuroprotective activity and are useful in the therapeutic treatment of neuronal loss in hypoxia, hypoglycemia, brain or spinal cord ischemia, and brain or spinal chord trauma as well as being useful for the treatment of epilepsy, Alzheimer's disease, Amyotrophic Lateral Sclerosis, Parkinson's disease, Huntington's disease, Down's Syndrome, Korsakoff's disease and other neurodegenerative disorders.

Abstract: Un dispositif de fixation (1) destiné à être utilisé en maçonnerie comprend à l'état d'ébauche une tige cylindrique droite (2) en acier. Une configuration nervure-cannelure-nervure s'étend de manière hélicoïdale le long de la partie inférieure (4) de la tige (2) et comprend deux nervures parallèles opposées (7) en saillie par rapport à une partie plane (9). Chaque nervure forme avec la nervure adjacente une cannelure (5). Au moins l'extrémité antérieure de la partie inférieure (4) de la tige (2) est conformée de façon à obtenir un dispositif de type autotaraudeux. Lors de l'utilisation, on introduit le dispositif de fixation dans un alésage percé préalablement dans un substrat de maçonnerie tel que de la brique en le vissant de façon à former un filetage sur les parois internes de l'alésage. La dimension axiale de la partie plane (9) est d'au moins 50 % du diamètre de l'ébauche. Il en résulte que des quantités relativement importantes de matériau de substrat sont disposées entre les configurations nervure-cannelure-nervure lorsque le dispositif de fixation est en place. Les résistances à l'arrachement résultantes de l'utilisation du dispositif de fixation dans des strructures de maçonnerie sont supérieures à la plupart de celles des dispositifs de fixation disponibles. De plus, le dispositif s'avère moins coûteux et plus facile à utiliser que les boulons fendus traditionnels.

Abstract: The invention relates to a process and device for monitoring the operativeness of the heater of an oxygen sensor which is arranged in the exhaust gas channel of an internal combustion engine. The function principle of the invention is based on the fact that the supply voltage of the heater of the sensor drops when loaded with the electrical resistance of the heating element, the difference in voltage depending on the size of the resistance and thus at least the three states of heating/normal operation, disconnected state, short-circuit, can be differentiated. The operating state of the heater of the sensor which is determined in this way is indicated to the driver by actuating an appropriate monitoring device and/or is possibly stored in an error memory. The device according to the invention can be realised by a computer or in a compact design and is thus suitable for use in a central control device. <IMAGE>
