  • Patent number: 7658669
    Abstract: A cabin pressure control system (CPCS) software control logic modification may boost the voltage applied to a motor when conditions are sensed indicating a combination of larger than normal cabin pressure and cabin rate error conditions. The motor may be part of an open-loop system for operating a butterfly valve that may regulate outflow from the aircraft cabin. The larger than normal cabin pressure and cabin rate error conditions may be an indication that the outflow valve is not responding in a normal manner, potentially caused by excessive loading to the motor or motor degradation. By boosting the motor voltage during excessive load conditions or with a degraded motor, CPCS performance and robustness may be improved.

  • Patent number: 7299383
    Abstract: The method is implemented with a management system of the time-triggered architecture type in association with a processor of a central processor unit that possesses a privileged execution mode to which access is protected by an instruction of the “call to system layer” type. The only system layer call that is authorized from an application task under consideration to the system layer consists in reporting a change of node in the control graph of the task in question. When the system layer has verified that the call is legal relative to the execution paths of the control graph as described in the constant tables of the application, all of the operations to be performed on the node in question by the system layer are predetermined by the constant tables of the application associated with the system layer.

  • Patent number: 6490475
    Abstract: A system employs a tracker and a set of substantially non-shadowing point markers, arranged in a fixed pattern or set in a fluoroscope calibration fixture that is imaged in each shot. The fixture is preferably affixed to the image detector of the fluoroscope, and tracking elements secured with respect to the fixture and at least one of a tool and the patient, provide respective position data irrespective of movement. A marker detection module identifies markers imaged in each shot, and a processor applies the known marker positions to model the projection geometry, e.g., camera axis and focus, for the shot and, together with the tracked tool position, form a corrected tool navigation image. In one embodiment an inverting distortion correction converts the tracked or actual location of the tool and displays the tool on the fluoroscopic image to guide the surgeon in tool navigation.

  • Patent number: 5014224
    Abstract: In a tactile sensor, a first conductive path made of an electrically resistive material, which is elastic, is fixed to a foil-like base. At points of intersection with good electrically conducting conductive paths, which are fixed to a second elastic foil, the first conductive path has a uniformly curved convex surface. If pressure is exerted on the second flat foil, then the convex surface of the first conductive path is deformed in the area where the pressure is exerted so that, in this area, the first good electrically conducting conductive path presses against the first conductive path over a pressure-responsive longitudinal area, so that the total resistance of the first conductive path changes in a pressure-responsive manner. By measuring the total resistance and the potential of the good electrically conducting conductive paths, the pressure exertion can be determined as to location and amount of pressure.

  • Patent number: 4962365
    Abstract: A resistor (10) includes a resistive filling (28) formed within a trench (12) and separated therefrom by an insulating layer (26). Resistive filling (28) is of the same type of semiconductor material as that of second layer (22), but of an opposite extreme of dopant concentration. A head region (32) may be formed below interface (30) within second layer (22) to more clearly delineate the edge of resistive filling (28) from second layer (22). Where resistive filling (28) is of a low dopant concentration, low resistance contact region (34) is formed of a high dopant concentration in order to provide a minimum resistance contact to resistive filling (28).

  • Patent number: 4954696
    Abstract: A self-regulating heating article includes a first elongate layer formed by a crystalline polymeric composition of high crystallinity and conductive particles dispersed in the polymeric composition to exhibit a positive temperature coefficient of resistance. A pair of elongate electrodes, which are adapted for connection to a power supply, are secured one on each surface of the first layer to develop a potential in the direction of thickness of the first layer. The electrodes are arranged so that a creeping distance which is greater than the thickness of the first layer is established between the electrodes along peripheral edges thereof. The creeping distance prevents insulation breakdown and ensures safe, high wattage operation at power supply voltages.
