The present application concerns detecting catheter proximity to a blood-vessel wall and blood-vessel wall artifacts associated therewith. In one embodiment, a light source, in a catheter, can be used to project light into the blood vessel. An intensity associated with at least one light wavelength that interacted with blood can be measured. Based on the measured intensity, a determination can be made regarding blood-vessel wall artifacts due to the catheter tip proximity to a blood-vessel wall. Feedback can be provided to the clinician in order to assist the clinician in adjusting the catheter to optimize signal quality and minimize artifacts due to the blood-vessel wall.

Detection of blood-vessel wall artifacts

An optical article comprising a plurality of optically detectable marks disposed on a surface of the optical article; a removable electrical device disposed on the surface of the optical article; wherein the electrical device is operatively coupled to the optical article; and wherein the electrical device is configured to interact with an activation signal when brought in direct contact with a communication device that applies the activation signal to the electrical device. A removable electrical device is also provided. A system and a method for activation are also provided.

Activation system and method for activating an optical article

An equipment comprising a receptacle for receiving an optical article; a first set of electrical connectors configured to be in direct contact with a second set of electrical connectors disposed on the optical article, when the optical article is received by the receptacle; an activation device operably coupled with the first set of electrical connectors; wherein the activation device is configured to generate an activation signal which is transmitted to the second set of electrical connectors by the first set of electrical connectors, wherein an electrical device is configured to provide a power component to the optical article via the first set of electrical connectors and the second set of electrical connectors which are in direct contact. A system comprising the equipment is also provided. Also provided is a checkout device.

A fiber-optic dynamic sensing module comprises a support member, a beam extending from the support member, and a pre-strained fiber Bragg grating sensor and a strain-free fiber Bragg grating sensor mounted on the beam. The pre-strained and strain-free fiber Bragg grating sensors each comprise a Bragg grating inscribed in a fiber. The Bragg grating of the pre-strained fiber Bragg grating sensor is packaged more tightly along a longitudinal direction of the beam than the Bragg grating of the strain-free fiber Bragg grating sensor.
