Abstract: A bipolar transistor is manufactured by: forming a collector region; forming a first layer made of a material of a base region and an insulating second layer; forming a cavity reaching the collector region; forming a portion of the collector region and a portion of the base region in the cavity; forming an insulating fourth layer made of a same material as the insulating second layer in the periphery of the bottom of the cavity, the insulating fourth layer having a same thickness as the insulating second layer; forming an emitter region; and simultaneously removing the insulating second and a portion of the insulating fourth layer not covered by the emitter region.

Abstract: An electronic device includes an insulating first layer covering a second layer made of a doped semiconductor material. A cavity is formed to cross through the first layer and reach the second layer. Insulating spacers are forming against lateral walls of the cavity. A first doped semiconductor region fills the cavity. The first doped semiconductor region has a doping concentration decreasing from the second layer.

Abstract: The method can include a muscle deforming a fiber path and activating a joint of the mammal, circulating electricity along the fiber, along the length of the fiber path, generating a movement signal including monitoring a change of impedance of the fiber stemming from the deformation of the muscle path during said deformation of the fiber path, determining a coefficient of correlation value of successive portions of the movement signal associated to corresponding, successive, time windows, including ascertaining a degree of similitude between the corresponding portion and a corresponding movement template, and generating an indication of muscle fatigue based on said coefficient of correlation values.

Abstract: An improved method and device for reflectively measuring a subject such as a throat area in a vane ring for a gas turbine engine uses improved lighting arrangements to improve the quality of reflection to thereby reduce problems associated with poor quality reflection which may adversely affect the image processing and thus reduce the accuracy of measurement.

Abstract: A device and method for measuring an area such as a throat area in a vane ring for gas turbine engines. Measurement inaccuracy introduced by image size changes as a result of the position deviation of the selected throat relative to a desired datum is reduced as a result of the improved system disclosed.
