Abstract:
An exoskeletal measurement system (10) for simultaneously monitoring load and motion on the human body includes: means for sensing the motion of a joint (16); means for detecting the load (32) on a human link segment remote from that joint; and means for correlating (36) simultaneously the motion of the joint and the load on the human link segment for representing the stress on the human body.
Abstract:
A system to record the color, size and location of skin blemishes on the skin using an objective standard is provided. The system includes a color scale (102) containing colors and shades of colors sufficient to portray a skin blemish; a distance scale (113) for measuring the distance of the blemish from reference points; and a body map (11) of the skin surface of the entire human body with reference points for recording the location of the blemish. Each color in the color scale and size in the size gauge is given an individual designation for easy reference. The color scale and the measuring devices may be combined in one multifunctional tool and with a folded chart (11) for easy storage in a folder (81) to protect the colors from changes due to exposure to light.
Abstract:
The invention relates to a process for measuring the dimensions of a space, in particular a buccal cavity with upper and lower jaw dentition, using a scanning device which is introduced, at least partially, into the space to be measured, and to a device for carrying out this process. To obtain exact and essentially error-free measurement results, in particular in relation to the shape in particular of the translucent teeth of the upper and lower jaw dentitions, rapidly and with simple manipulation, the scanning device used is an optical measurement device whose optical signals are converted into electronic signals which can be evaluated in a computer. The device for carrying out this process is essentially characterized by a source of optical radiation located in a preferably extra-oral section of the device and a projection device with a projection optical system which projects optical radiation onto the surfaces and/or translucent internal volume of the buccal cavity, and the coloured translucent volume of the teeth, a recording device with a recording optical system which records the radiation reflected from the surfaces and/or the translucent internal volume, and an evaluation device, located preferably in an extra-oral section of the device, which evaluates the recorded reflected radiation.
Abstract:
The invention relates to a method for non-invasively measuring skin structure. Infrared radiation from a plurality of locations over an area of skin under investigation is measured so as to give an indication of the variation in papillary dermis thickness over said area, and the skin colour coordinates at a plurality of locations over the same area of skin is also measured. The data obtained is used to calculate corrected skin colour coordinates over the area corresponding to a predetermined papillary dermis thickness. The corrected skin colour coordinates so obtained are compared with a reference colour coordinate range for healthy skin of the same predetermined papillary dermis thickness. At an abnormal region, where the corrected skin colour coordinates lie outside the reference colour coordinate range, the depth of penetration of dermal melanin can be measured.

This invention concerns a process and device for carrying out a venous plethysmography using compression with a strain gauge or by direct peripheral measurement, the calibration of the measurement device being automatic.
Abstract:
A device for measuring the sebum secretion rate of the scalp, including a probe provided with a light flux transmitter (102) and a translucent element (104) designed to be placed on a portion of the scalp to collect sebum; and a receiver (113) for measuring the light flux transmitted from the transmitter through the translucent element previously placed on said portion of the scalp, and comparing the measurement with a reference signal. Said translucent element is a frosted glass disc with a working contact area having a diameter of approximately 1-3 mm, and the light flux transmitter is an LED transmitting in the green spectrum.
Abstract:
A device for estimating (in vivo) skin wrinkling, including (a) movable means for forming wrinkles on an examined skin area (Z) in a direction parallel thereto, (b) movable means (D) for scanning the wrinkled skin area using an incident light beam (L) from a light source, (c) position sensing detectors (PSD) for recording the light (L1) reflected by the wrinkled skin, (d) means for converting the sensed light into an electrical signal, and (e) means (T) for extracting at least one representative parameter of the wrinkled skin profile from the electrical signal. A method carried out by means of the device is also disclosed. The method is useful for serially estimating the mechanical properties of the dermis, e.g. the resiliency and firmness thereof, as well as skin ageing, and for estimating the effectiveness of products intended to control same.
Abstract:
Apparatus for and a method of assessing balance performance has a platform (11) which overlies a baseplate (10). At least two flexible tubes (12 and 13) are positioned between the baseplate (10) and platform (11) with at least the major part of each such tube positioned below a defined area A and B respectively of the platform. Each tube (12, 13) is closed and is connected to one or more differential pressure transducers (16) in such a manner that the electrical output (17) from the or each transducer depends upon the relative pressures of the tubes (12, 13) connected thereto. The electrical outputs (17) are analysed by a processing unit which drives a display to provide real-time feedback to a user of the apparatus, indicative of the user's balance performance.
Abstract:
Tissue is examined with a device (34) that includes one or more transducer elements (36), each of which generates a signal in response to force imposed on the transducer element (36) in accordance with varying properties of an underlying tissue structure (32) as the transducer element (36) is pressed against and moved over the tissue (32). The tissue examination device (36) further includes circuitry for detecting a variation in the signals as an indication of a composition of the underlying tissue structure (32).
Abstract:
A medical condition quantification and dysfunction reduction therapy evaluation process enables a health care service provider to monitor the improvement of a patient's condition, as well as the efficiency of the rehabilitation process employed to achieve a patient improvement objective. Based upon initial patient examination data (200), one or more sets of parameters associated with respective body regions, for which dysfunction reducing therapy is to be carried out, are provided. For each parameter, a data value is generated. The magnitude of the data value is based upon the condition of the body region associated with the parameter. All of the data values of the parameters of a body region are combined (206), to quantify the overall condition or dysfunction of the body region. Periodically, during the course of the patient therapy program, the physical condition of the body region being treated is re-examined (203, 205).
