20080306396 | High-Sensitivity Sensors for Sensing Various Physiological Phenomena, Particularly Useful in Anti-Snoring Apparatus and Methods - A mechanical vibration sensor adapted to be brought into contact with an object for sensing mechanical vibrations in the object, includes a body of a soft elastomeric material having high transmissivity and low attenuation properties with respect to a preselected type of energy waves; and a pair of transducers mounted, by mounting members having high attenuation properties with respect to the energy waves, in spaced relationship to each other to define a transmission channel between the transducers. Such sensor is particularly useful in a method and apparatus for controlling snoring by a person, by utilizing a stimulus device effective, when sensing snoring, to immediately produce a response in the person tending to interrupt the person's snoring. | 12-11-2008 |
20080307885 | Method and Apparatus for Precisely Measuring Wire Tension and Other Conditions, and High-Sensitivity Vibration Sensor Constructed in Accordance Therewith - A method and apparatus for monitoring a predetermined condition of a medium by; transmitting acoustical waves through the medium, continuously measuring changes in the transit time of the acoustical waves resulting from changes in the monitored condition; and utilizing the changes in transit time to provide a continuous measurement of the changes in the monitored condition. The acoustical waves are bending waves wherein cross-sections of the medium have a rotational movement orthogonally to the axis of propagation of the waves through the acoustical channel. Several examples of such method and apparatus are described, including a highly sensitive pressure sensor for sensing changes in pressure applied to a displaceable membrane, and a highly-sensitive vibration sensor for sensing earth or other vibrations. | 12-18-2008 |
20090241691 | METHOD AND APPARATUS FOR MEASURING FORCE PARTICULARLY TORQUE - A method and apparatus for measuring the force applied by a first member coupled to a second member by a connecting body, by: transmitting a cyclically-repeating energy wave through the connecting body from a first location thereon to a second location thereon; measuring the transit time of the cyclically-repeating energy wave from the first location to the second location; and utilizing the measured transit time to produce a measurement of the force. In the preferred described embodiment, the connecting body is a fastening plate which fastens a drive shaft to a driven shaft and measures the torque output of the drive shaft. | 10-01-2009 |
20100152584 | METHOD FOR MEASURING VARIOUS PARAMETERS OF BONES AND JOINTS - A method of measuring a predetermined parameter of interest in a bone or joint of a subject's body, comprising embedding in the bone or joint an acoustical transmitter and an acoustical receiver spaced from the transmitter to define between them an acoustical transmission channel which includes a portion of the bone or joint exhibiting the predetermined parameter of interest, measuring the transit time of an acoustical wave transmitted through the acoustical transmission channel from the transmitter to the receiver, and utilizing the measured transit time to provide a measurement of the predetermined parameter of interest. | 06-17-2010 |
20100206091 | APPARATUS FOR MEASURING COMPONENTS OF A POINT FORCE - Apparatus for measuring components of a point force includes a first rigid member having an outer surface to receive the point force to be measured, and three spherical force transmitting elements, each of spherical or partial-spherical configuration, projecting from its inner surface, and a second rigid member having an inner surface facing the inner surface of the first member and formed with three sockets for receiving the three spherical force transmitting elements, each of the sockets includes two planar walls diverging in the direction towards the inner surface of the second member so as to be engaged by the respective spherical force transmitting element of the first member at two contact points, and to space apart the inner surfaces of the first and second members. A force sensor is located at each of the two contact points of each of the spherical force transmitting elements to sense the force applied by the respective spherical force transmitting element to each of the two planar surfaces of the second member. | 08-19-2010 |
20100210919 | METHOD AND APPARATUS FOR MONITORING PREDETERMINED PARAMETERS IN A BODY - A method and apparatus for monitoring a predetermined parameter of interest in a body, includes: applying to the body a sensor including an acoustical transmitter and an acoustical receiver spaced from the transmitter to define between them an acoustical transmission channel which includes a part of the body exhibiting the parameter of interest; and monitoring from a remote location the transit time of an acoustical wave transmitted through the acoustical transmission channel from the acoustical transmitter to the acoustical receiver, the monitored transit time being influenced by the parameter of interest and thereby providing a measurement of the parameter of interest. The method and apparatus are particularly useful for monitoring functions of various organs (e.g. the liver, kidneys, lungs, heart, etc.) in a living body but may also be used in non-medical applications, such as for measuring water seepage in concrete. | 08-19-2010 |
20100234750 | APPARATUS AND METHOD FOR DETECTING BREATHING DISORDERS - Apparatus for detecting breathing disorders in a person, comprising a sensor constructed to be located on, in, or under a mattress to sense mechanical vibrations of a body part of the person while lying on the mattress, and a control system designed to receive the output of the sensor, and to perform the following operations:
