Abstract: Embodiments of present disclosure relates to method and device for controlled emission of radiation. Device comprises probe unit, sensor unit and switch unit. Probe unit is configured to emit radiation on surface of object. Probe unit is supported, via an elastic, to supporting structure of device. Sensor unit is placed at predefined distance from probe unit, along supporting structure, to establish contact with surface. Sensor unit comprises flexible material, mounted to supporting structure, with cavity and first force sensing unit placed in cavity of flexible material. First force sensing unit is configured to detect first force transferred from surface sensor unit. Switch unit is configured to control emission of radiation on surface, based on first force detected by first force sensing unit, upon contact of sensor unit with surface and identification of probe unit to be one of in contact with surface or at minimal distance from surface.

Abstract: The present disclosure discloses a mechanism for aligning and orienting a probe in an optical system. The mechanism includes a sensor head, which are defined with one or more provisions. Further, the mechanism includes at least one block member, which is movably disposed within the one or more provisions in the sensor head. The at least one block member is defined with a cavity to accommodate a probe. During contact of the probe with a surface of the subject, a torque is generated, which facilitates in aligning the probe on the surface of the subject. The block member is configured to tilt corresponding to movement of the probe, for aligning the probe at an angle on the surface of the subject.

Abstract: The present disclosure discloses a disposable cover (4) for covering a head (8) of an optical device (1) and contacting a subject for examination. The cover includes a body (21), defining a first surface (19) and a second surface (20). The body (21) is removably connectable to the head through the first surface and the second surface, where one or more apertures (6) are defined in the first surface (20). A flexible cap (7) is disposed of in each of the one or more apertures of the body, where at least a portion of the flexible cap is made of a substantially transparent material. The flexible cap is structured to accommodate an optical probe (3) extending from the head of the optical device, such that the optical probe extends and retract relative to the body based on position of the optical device relative to the subject.

Abstract: Present disclosure describes the method and system for detecting the brain condition state of a subject. Method comprising calibrating a power zone of the system in real-time and detecting a reflected signal for each of a plurality of transmitted input signals on scanning each of lobe locations of the subject after calibration. Thereafter, method comprising validating an array generated using the plurality of transmitted input signal and corresponding reflected signal for each of the lobe locations and generating a lobe fit value for the validated array using a curve fitting technique. Subsequently, method comprising computing logarithmic ratios corresponding to four pairs of contralateral lobe location, six pairs of ipsilateral lobe locations in left hemisphere and six pairs of ipsilateral lobe locations in right hemisphere using the lobe fit value and classifying the logarithmic ratios into one of brain condition state classes by comparing with pre-labelled logarithmic ratios stored in system.

Abstract: The present disclosure discloses a guarding wall mechanism (100) for an optical fiber (101). The mechanism (100) comprises a housing (202) adapted to house the optical fiber (101), wherein the housing (202) defines a space (108) between the optical fiber (101) and a guarding wall of the housing (202). A plurality of suction units (103) disposed in the space (108). Each of the plurality of suction units (103) are configured to selectively exert suction pressure on an examination surface in contact with a free end (109) of the optical fiber (101). The guarding wall mechanism (100) of the present disclosure eliminates leakage of light and reduces Fresnel losses. Also, the mechanism (100) improves comfort to the patient during examination.
