Abstract:
In a medical diagnosis computer system, a method for using a video data signal (12) including x-ray fluoroscopy, and an analog physiological data signal (10), including electrocardiogram and electrogram data signals, wherein the video data signal (12) and the analog physiological data signal (10) are received, sampled, and simultaneously displayed (34) and sent to storage (28). Live and frozen data signals are analyzed and processed to provide correlated angiographical, electrophysiological, and radiological data. The data signals are then displayed simultaneously on one or more display monitors (28) in separate windows. The medical system provides processor, memory, storage, and output devices.
Abstract:
Apparatus for monitoring performance during exercises up setting balance, enabling the user to correct his balance with his arms so that he can become autonomous. The apparatus comprises a holding grip (1) connected to a sensor system (2) detecting the forces applied by the user to regain his balance. A securing device (3) removably or permanently connects the handle to any stable structure. A device (4) receives signals from the sensor and processes data to indicate when the user has to hold the grip. The apparatus of the invention is useful mainly for diagnosing and correcting a balance disorder and is intended particularly for the elderly.
Abstract:
A bone-stiffness measuring instrument comprises a set or kit of readily assembled and adjusted components, namely a goniometer (16), a light-weight load cell (15), and a small computer package (22), adapted to continuously respond to the outputs of the load cell and goniometer and to display and/or record (i.e., store) measured stiffness data; plus hardware in duplicate, namely, a bone-screw clamp (18, 20) and bracket for fixed reference to bone-screws that are externally exposed on each of the respective sides of the fracture (following removal of an external fixator), a stiff arcuate arm member of radius at least twice the diameter of the fractured bone, and a goniometer-end mount. The arcuate arm member is adjustably fixed to the bracket for bone-screw reference, and the goniometer-end mount is also adjustably fixed to the arcuate arm member, with a releasably lockable-ball-joint connection for adjusted orientation of an end mounting to the goniometer.
Abstract:
Apparatus (1) for selectively and sequentially communicating a subject with a plurality of substances for detecting the electrical reactance of the subject to the substances comprises a plurality of discrete containers (8) for the substances mounted on a printed circuit board (7). The containers (8) are connected to a first conductor (9) through a plurality of transistors (T1 to T4000). The first conductor (9) terminates in a first contact member (15) in a head harness (16) for communicating the substances with the forehead of the subject. A signal generator (4) generates binary coded digital signals in ASCII form which correspond to the respective substances and are sequentially and simultaneously applied to the subject with the corresponding substance through a second contact member (24) located in the head harness (16). A plurality of third contact members (25a) to (25l), six of which are in the head harness (16) monitor the electrical reactance of the subject at the locations of the third contact members (25). A computer (5) analyses the monitored electrical reactances of the subject.
Abstract:
This invention is an apparatus for measuring and visually displaying a user's body movement while performing a motion. Sensing means (22) such as a potentiometer, are coupled to the joints of a user in order to quantitatively detect movement of the user's body while performing a motion. The sensors (22) generate signals indicative of the motion and are received by processor means (30) which in turn connects to a display means (32) for graphically displaying at least one image representing the movement. A second image may be displayed with the first image for comparison purposes.
Abstract:
A method and system are provided for sensing eye motion, such as saccadic eye motion, in a non-intrusive fashion. An optical delivery arrangement (105) converts a laser beam pulse (104) into a plurality of light spots (21-24). The light spots are focused such that they are incident on a corresponding plurality of positions located on a boundary (12) whose motion is coincident with that of eye movement. The boundary can be defined by two visually adjoining surfaces having different coefficients of reflection. Energy is reflected from each of the positions located on the boundary receiving the light spots. An optical receiving arrangement (156) detects the reflected energy from each of the positions. Changes in reflected energy at one or more of the positions is indicative of eye motion.
Abstract:
A device (2) for use in assessing various characterics of a skin blemish, e.g. a mole, comprises two blemish assessment discs (4, 16)mounted for relative rotation and each carrying a scale of blemish criteria whereby a skin blemish may be positioned adjacent both scales and matched with the relevant portions thereof.
Abstract:
In this method for determination of the weight of human body force or pressure exerted by the foot (12) of the human body on supporting means (13) of the foot (12) is measured by sensing means (5) incorporated in a shoe (2) generating an electric signal proportional or analog to said force or pressure. The signals are transmitted to a remote area where they are indicated in the form of body weight data on the display (9) of a wrist watch (3).
Abstract:
A device for measuring faulty human bodily postures, e.g. of the pelvis, shoulder and/or spine, comprising a frame having a base component (2), two vertical and mutually parallel guides (4, 4') at a distance apart which is greater than the body-width of the patient to be measured and a horizontal rod (6) at the upper ends of the guides (4, 4'), whreby, to discover the geometry of faulty postures, there is on each guide (4, 4') at least one vertically movable and clampable holder (42, 42'), the vertical position of which can be quantitatively detected, and on each holder (42, 42') is fitted a horizontally movable detector arm (46, 46') to detect selected reference points of the patient's skeleton, in which the base component (2) has two adjacent movable balance plates (24, 24') for separately measuring the load on each of the patient's legs, the positions of which can be quantitatively detected, and the detector arms (46, 46') are substantially U-shaped in such a way that the end of the detector arm (46, 46') concerned fitted to the holder (42, 42') extends away from the space between the guides (4, 4') and its other end can be placed in the space between the guides (4, 4').
