Abstract: Apparatus is provided which enables the assessment of mobility of human and/or animal joints to be carried out. A flexible transducer (1,23) includes a conductive elastomer (2), which, when stretched, provides a change in an electrical output signal. The transducer is located over the joint to be investigated and during movement of the joint electrical signals from the transducer output which are a function of joint mobility, are produced. The signals are digitised and stored in a memory (17, 33) and are compared with a bank of data from normal and pathological subjects stored in a continuously updated memory (45, 34). When the comparison locates the 'best fit' between the joint movement and the stored data, the type of joint movement is classified and the result is presented on a visual display unit (43). The movement signal can be conditioned so that the angular displacement of the joint, the rate of joint movement, acceleration of the joint can be estimated and classified. The force produced by the joint can also be calculated using the acceleration and an estimate of the mass moved. This system permits the progress of an individual to be monitored and to identify joint movement characteristics in particular patient populations. The transducer, when combined in a composite unit with electrodes (27), is also used to accurately assess the degree of neuromuscular activity during and after anaesthesia.

Abstract: An analog signal, for example an E.C.G signal carrying a mains hum component is sampled by a sampler 3 and the sampler applied to a difference circuit 4. A feedback circuit from the output of circuit 4 to its other input includes a programmable gain amplifier 7 and a discrete sine wave generator 8. The sine wave generator operates at the frequency of the mains hum component and has its amplitude and phase controlled by the output of amplifier. The output from generator 8 controls the gain of amplifier 7 and is applied to circuit 4 to cancel the hum component of the samples.

Abstract: An automatic fingerprint enrollment and identification technique is provided for automatically processing an input image represented by pixels having either a one or a zero value. The automatic processing involves a series of steps in which the initial processing is a rough screening technique for eliminating a reasonable portion of the noise while passing through almost all of the minutia. As the steps proceed, the processing becomes more complex to provide a tighter screening out of noise while passing through as much of the minutia as possible. The later steps by operating on relatively fewer minutia or anomaly points that the earlier steps can be economical though more complex so as to be more discriminate than the earlier steps. The processing provides an optimum trade off between enrolling as large a proportion of the population as possible while minimizing the number of false identification errors.

Abstract: The invention concerns a novel apparatus for measuring the reflectance of a coloured area of skin in response to green light as a means for assessing the degree of erythema or pigmentation of the area of skin. The apparatus (shown in partial cross-section in Fig. 2) has a mutually screened, green light emitting diode (10) and photosensitive electrical component (8) (typically a cadmium sulphide photoresistor or a silicon photodiode), arranged in a holder (1) and connected to conventional electronic circuitry, so that the amount of light reflected by the area of skin and impinging on the component (8) may be measured and then displayed on a voltmeter allowing a quantitative assessment of erythema or pigmentation. The apparatus has both medical, veterinary and cosmetic applications, for example in assessing the response to treatment of inflammation of the skin, or a safe level of exposure to UV light.

Abstract: Bei Temperaturmeßfühlern mit Meßschaltung und einer an die Meßschaltung angeschlossenen und in einer Metall kappe angeordneten Meßperle werden zur Messung konta minierte Objekte über den Fühler im Bereich der Metallkappe geschlossene schlauchartige Folien gestülpt. Um sicherzu stellen, daß Temperaturmessungen nur dann vorgenommen werden können, wenn der Fühler mit einer Folie versehen ist, weist der Fühler eine Meßvorrichtung und die Folie ein die Meßvorrichtung beeinflussendes Teil auf. Die Meßvorrichtung gibt die Meßschaltung zur Temperaturmessung nur frei, wenn sie vom Teil auf der Folie beeinflußt wird.

The values of intensity of radiation emitted at different wavelenghts, at different distances between the lht introduction site (s) and the light collection site (s), and at different temperatures are collected and used in the method to generate a relationship between these values and the concentration of an analyte in the tissue or the disease state of a patient. The method involves the use of an algorithm that identifies artifacts in the data resulting from motion of the patient and allows the rejection of data sets that contain these artifacts. The algorithm identifies sudden changes in the magnitude and direction in a sequence of collected signals.
