Various embodiments of a light detection device (110) and a method of using such device (110) are disclosed. In one or more embodiments, the light detection device (110) includes a housing (112) including a top surface (114) and a bottom surface (116), where the housing (112) extends along a housing axis (104) between the top surface (114) and the bottom surface (116); and a support member (160) connected to the housing (112) and adapted to be selectively moved from a closed position to an open position. The support member (160) is further adapted to maintain the light detection device (110) in an upright position when the bottom surface (116) and the support member (160) are in contact with a working surface (102) and the support member (160) is in the open position.
Abstract:
A system for non-invasive radiation dosimetry comprises (a) a patch, which upon application conforms itself to the curvature of the surface to which it is attached, that comprises radiation sensitive functional cells which, under the influence of radiation, undergo physical and/or chemical changes that are expressed as a response signal taking the form of a measureable and quantifiable alteration in absorbance of a part of the electromagnetic wave spectrum; (b) a camera system which captures, during the exposure to radiation, the relevant part of the electromagnetic spectrum, emitted in the environment and reflected on the patch, in the form of a digital picture, and, as such, allows quantification of the radiation-modulated patch-light interaction properties; and (c) a software algorithm - running on a control unit - which converts the digital picture into an estimate of the dose the patch was exposed to.

Abstract:
The present application discloses device and system embodiments that address mobile device integration considerations for various categories of UV sensors, including cameras, photodiodes, and chemical sensors. The UV sensors may use the functionalities of the existing in-built sensors in conventional mobile devices, and/or integrate additional components specific to UV sensing. By optimally positioning the sensors, UV sensing and other collateral functionalities (e.g., charging a photovoltaic cell integrated with the mobile device) can be realized in parallel.
