Abstract: Apparatus and method for measuring Internal Ocular Pressure (IOP) comprises applying a perturbing vibration into an eye over a range of frequencies. A vibrational response of the surface of the eye is measured such as by using a laser velocimeter, the vibrational response including velocity and rate of change of the phase lag. Further, geometric properties such as volume of the eye are measured such as by using a laser interferometer to measure characteristics such as the eye's axial length and cornea thickness. Use of multiple characteristics normalizes the effect of an eye's mechanical and geometric properties and thereby more accurately determines the IOP.

Abstract: An infusion system has a capability to monitor infusion complications such as extravasation, tissue necrosis, infiltration, phlebitis, and blood clots. The infusion system has at least partially transparent flexible film barrier dressing in a flexible membrane that incorporates a plurality of sensors capable of detecting tissue condition and a control unit capable of coupling to the film barrier dressing that monitors signals from the sensors. A device is capable of executing non-invasive physiological measurements to characterize physiologic information from cross-sectional surface and subcutaneous tissue to detect the presence or absence of tissue conditions such as infiltration or extravasation during intravascular infusion. In some examples, the device utilizes depth-selective methods to sense, detect, quantify, monitor, and generate an alert notification of tissue parameters.

Abstract: Elongate medical devices such as guidewires can be formed from a core wire and a preformed distal cap that is configured to fit over a distal end of the core wire. The distal cap can be attached using a variety of techniques. In particular, the distal cap can be attached to the core wire using laser welding.

Abstract: A health administration apparatus 10 is provided, which is capable of dispensing with a troublesome measuring operation such as to wrap a tape measure or the like around a part of concern of a human body by automatically finding the abdominal circumference (waist size) or the lumbar circumference (hip size) of a human body. The health administration apparatus 10 is configured to allow entry of body data of an examinee, including the height and weight of the examinee, and to be capable of finding the abdominal circumference of the examinee which is the circumferential size of a trunk part of the examinee by a computation based on the body data including the height and the weight of the examinee.

Abstract: A system for the in vivo detection of the effects of AD in the interior of an eye. A scanning polarimeter, including a residual retardance canceling system and an improved anterior segment retardance compensator, produces an optical analysis signal representing the birefringence of the retinal nerve fiber layer (RNFL) structures of the eye. The birefringence data is more accurate because of compensation for anterior segment birefringence and residual birefringence of optical components, such as, for example, the beam splitters, lenses, scanners and retarders. An electrical analysis signal representing a large (20 by 40 degrees) retardance map is produced and evaluated by an artificial neural network to produce an analysis classification signal representing the contribution of Alzheimer's disease to the birefringence of the retinal layer corresponding to the relationship of the electrical analysis signal to an analysis signal database.
