This application is related to a head-mounted display system and related methods for entertainment, diagnostics, and treatment. The HMD includes various sensors and tools to take physical measurements, perform physical procedures, adjust physical conditions, or manipulate digital data. In some embodiments, the HMD produces different types of sensory stimuli, such as releasing or filtering certain compounds in liquid or aqueous forms in the space near the HMD, or adjusting different physical features of the space near the HMD, such as temperature and flow, to enhance the augmented or virtual reality environment being displayed. In some embodiments, the HMD performs regular monitoring, a specific examination, a surgical intervention, or other care procedures on the eyes automatically or in conjunction with a device of an eye care professional across a computer network to care for the user's eyes in real time or on an ongoing basis.

The present invention relates to a method of determining skin health of an area of skin by exposing the area of skin to a first exposure radiation to induce the area of skin to emit a first fluorescent emission, measuring the intensity of the first fluorescent emission, exposing the area of skin to a second exposure radiation to induce the area of skin to emit a second fluorescent emission, measuring the intensity of the second fluorescent emission, calculating a ratio of these intensities, and comparing the ratio to a control ratio.

A PEFS (Piezoelectric Finger Sensor) acts as an electronic finger capable of accurately and non-destructively measuring both the Young's compression modulus and shear modulus of tissues with gentle touches to the surface. The PEFS measures both the Young's compression modulus and shear modulus variations in tissue generating a less than one-millimeter spatial resolution up to a depth of several centimeters. This offers great potential for in-vivo early detection of diseases. A portable hand-held device is also disclosed. The PEF offers superior sensitivity.

The present invention relates to an optical device for imaging and measuring characteristics of an objects surface shape, surface spectral reflectance and structure of sub-surface layers. In particular, the invention relates to imaging of topography of human skin and skin sub-surface layers and determination of concentration of skin constituents. The present invention has applications in areas such as skin care, dermatology, cosmetics, wound management and tricology. The imaging device of the invention significantly improves photometric stereo measurements by suppressing specular reflection and allows accurate determination of the surface shape. Consequently the device allows elimination of the influence of the shape and illumination conditions on spectral measurements and allows accurate measurement of skin constituents.

Systems and methods deform the surface of the material with a probe, such as a mechanical device or a gas/liquid jet, while optically recording in detail the three-dimensional (3D) topography of the resulting surface deformation. The probe effectively applies a forcing function to the material, the attributes of which are known by performing calibrations prior to use or by direct measurement while it is applied. The topography is effectively the system output that is measured as indicative of the underlying mechanical properties of the material. In one application, systems and methods that apply a pressure in-vivo to human tissue and analyze a three-dimensional topography of the resulting surface deformation to identify localized inhomogeneities and anomalies in the human tissue.

Apparatus are provided for monitoring a condition of a tissue based on a measurement of an electrical property of the tissue. In an example, the electrical property of the tissue is performed using an apparatus disposed above the tissue, where the apparatus includes at least two conductive structures, each having a non-linear configuration, where the at least two conductive structures are disposed substantially parallel to each other. In another example, the electrical property of the tissue is performed using an apparatus disposed above the tissue, where the apparatus includes at least one inductor structure.
