    摘要: The present document describes a pressure guidewire comprising: a shaft tube with a proximal section; a middle section extending from the proximal section of the shaft tube, the middle section having greater flexibility than the proximal section; an inner hypotube installed substantially within the middle section for optimal mechanical properties; a pressure sensor with a communication means routed through the middle section and the proximal section; and a sensor housing for receiving the pressure sensor. There are also described methods for joining the inner hypotube to the shaft tube.

    摘要: The present invention provides an optical sensor for monitoring current or power in a monitored element of a device such as a bridge-wire or hot-wire of electro-explosive devices. The optical sensor comprises an optical sensor made of semiconductor material. The semiconductor material comprises an absorption edge which is sensitive to a temperature variation. The semiconductor material is for placing in thermal contact with the monitored element of the device, whereby, when the current or power varies in the monitored element, it causes a variation in temperature in the semiconductor element and hence a spectral shift of the absorption edge which can be measured and which is representative of current and power variation.

    摘要: There is described a miniature fiber optic pressure sensor design where sensitivity around specific biased pressure is optimized. In an embodiment, the pressure sensor is a Fabry-Perot (FP) sensor which comprises a substrate; and a diaphragm mounted on the substrate. The diaphragm has a center and comprises: a first layer comprising a first material; and a second layer comprising a second material. The second layer forms a dot or a ring. The dot or ring is mounted on the first layer and is centered about the center of the diaphragm. The second material comprises internal pre-stresses to cause the center of the diaphragm (in the case of a dot) or the peripheral area about the center of the diaphragm (in the case of a ring) to camber away from the substrate upon relaxing the internal pre-stresses.
