Abstract:
A device for registration of motions or positions of a body (7) or a body includes at least one sensor unit (8) which is to be attached to the body or body portion intended to be registered. A registration unit (11) divides the measuring interval into a number of partial intervals and registers information about the body motions. The number of occasions is indicated, in which the motion or position of the body is located within each partial interval and about the duration for this motion or this position in each separate partial interval. By means of a reading unit (12, 26) the registered information can be read.
Abstract:
A sensor support base (10) having a rigid inner portion (11) and a relatively flexible outer ring portion (13) removably attached around its periphery for adhesive application to a patient is disclosed . The relatively flexible outer ring portion (13) has a relatively rigid segment (23) for assisting in attachment to the periphery of the inner portion (11). A layer of absorbent material (29) on the upper surface of the outer ring portion (13) is used for absorbing perspiration of the patient.
Abstract:
The apparatus is comprised of a detection pad or filler (2) made of flexible material and so conformed that a local depression caused by a nodule (N) sets an alarm. The detection pad (2) has two conducting surfaces (3, 4) separated from each other by the flexible material (5) for example foam, and of which the contact resulting from the local depression sets the alarm.
Abstract:
A method and apparatus for monitoring the location of a fetus in a birth canal during labor. The conductors (26, 28) of a fetal monitor probe (2), such as a fetal heartbeat monitor electrode, are marked with calibration means (101-120) corresponding to predetermined distances from a babyward end (20) of the probe (2). The babyward end (20) of the probe (2) is attached to the baby. During labor, the position and progress of the fetus on the birth canal may be inferred by observing the calibration means (101-120) relative to the outer end of the birth canal.
Abstract:
An upper extremity evaluation system includes a computer and a directly connected three-dimensional position locator which may be used by a therapist to enter data corresponding to the location of the flexed and extended joints of the hand, wrist and elbow. The computer may then utilize these dimensions in calculating angles of flexion and extension, and a degree of disability in accordance with American Medical Association standards.
Abstract:
A periodontal probe system for measurement, storage, and display of periodontal pocket depth, gingival level, and periodontal attachment level of the teeth. A periodontal probe instrument (12) includes an elongate tip (18) with a measurement arrangement (20) that simultaneously measures periodontal pocket depth, gingival level, and periodontal attachment level at each of a plurality of probe sites around a tooth. A pressure sensor (76) in the probe (12) provides a pressure signal indicative of the pressure acting on the tip (18) of the probe (12). A periodontal measurement is made by inserting the tip (18) of the probe (12) into a gum pocket and gradually increasing the pressure on the probe tip (18) after insertion. At a predetermined pressure level, the signal processing apparatus (20) samples the depth signals and converts them into measurement signals corresponding to pocket depth and attachment level.
Abstract:
For the manufacturing of interlinings or similar, the part of the body (1) of a person for which the interlining is intended is brought into a defined position with respect to an electronic measuring arrangement (2). During the measurement of the forces acting in two or three dimensions, the output signals of the said arrangement corresponding to the distribution of the compressive forces are transmitted to a computer (3) and compared with a stored sentence of theoretical values (ideal data). The differences between the measured distribution and the ideal distribution model are used to control a device (4) for manufacturing interlinings (or seat surfaces, reclining furniture surfaces, dentures) of suitable shape and rigidity.
Abstract:
The apparatus comprises a current source, means for measuring the sensitivity of the skin comprising a photovoltaic cell (14) measuring the light of a light source (16) reflected by the skin when the apparatus is applied against the skin, means (7) for introducing the sun exposure time means (12) for measuring the UV radiation intensity, means (8) for storing said parameters, an electronic computer (8) determining the protection index of the antisolar product to be used as a function of the skin sensitivity, the sun exposure time and the UV radiation intensity, display means (6) for displaying at least the exposure time and the protection index, and function selection means (5).
Abstract:
An apparatus and method for testing the strength of a person's muscles or muscle groups. The apparatus comprises a support frame (102) with associated elements such as a graduated guide post (104) and an adjustable support arm (106) to carry a force sensing device (110). The sensing device (110) is contacted by an area of the person's body (e.g. fist, knee, thigh) which is subjected to a force from the selected muscle or muscle group and generates an initial signal, such as an electrical voltage, in response to the force applied. The initial signal is processed and the resultant signal, representing the force applied, is displayed. The apparatus and method are well suited for testing muscle damage or recovery, for example for insurance or therapeutic purposes, and for comparing corresponding muscles, such as comparing selected muscles on the left of the body with those on the right.
Abstract:
To recognize fingerprints it is proposed to effect scanning by ultrasonic waves. For the purpose of comparison, an acoustic hologram (11) of the features of the finger concerned, inserted in an identification card, can be used, said hologram being compared with an ultrasonic interference specimen which is obtained by the reflection of ultrasonic waves on an interface formed between the surface of the finger (4) and a flat application surface (1).
