The present invention relates to a pressure-measuring foot hoard having a sturdy structure which may be used in an exercise apparatus capable of precisely measuring and correcting the state of imbalance of the body of a user, and to an exercise apparatus for correcting the state of imbalance of the body comprising the pressure-measuring foot board. The pressure-measuring foot board according to the present invention may firmly fix a pressure-measuring element for measuring the state of imbalance of the body of a user while also preventing or minimizing damage to the elements of the foot board, including the pressure-measuring element, when the foot board is being tilted for balancing exercises. Moreover, an exercise apparatus for correcting the state of imbalance of the body may be provided which can, by means of the pressure-measuring foot board, precisely measure the state of imbalance of the body, and, on the basis thereof, provide corrective exercises that are suitable for the amount of imbalance of each individual's body.

A surgical apparatus configured to be placed in the musculoskeletal system to precisely separate a first bone from a second bone. The surgical apparatus has one or more sensors to measure one or more parameters and supports one or more bone cuts for installing a prosthetic component. The surgical apparatus has at least one distraction mechanism configured to increase or decrease a height between a first support structure and a second support structure. A tilt mechanism comprises the at least one distraction mechanism. The tilt mechanism couples through a first pivot point and a second pivot point and adjusts a tilt of the second support structure relative to the first support structure. In one embodiment, loading applied to the second support structure is distributed between the first pivot point and the second pivot point during operation of the surgical apparatus.

A system is disclosed herein for providing a kinetic assessment and preparation of a prosthetic joint comprising one or more prosthetic components. The system comprises a prosthetic component including sensors and circuitry configured to measure load, position of load, and joint alignment. The system further includes a remote system for receiving, processing, and displaying quantitative measurements from the sensors. The kinetic assessment measures joint alignment under loading that will be similar to that of a final joint installation. The kinetic assessment can use trial or permanent prosthetic components. Furthermore, adjustments can be made to the applied load magnitude, position of load, and joint alignment by various means to fine-tune an installation. The kinetic assessment increases both performance and reliability of the installed joint by reducing error that is introduced by elements that load or modify the joint dynamics not taken into account by prior assessment methods.

A system, method and computer program product for determining user-specific weights usable to synthesize sensor data at void locations in a sensor array. Initial estimation weights are determined for the void locations. Sensor readings are obtained from a plurality of sensors while a user performs predefined actions. The sensors are arranged in a first pattern that maps the sensors to respective locations on the wearable device. Synthesized sensor readings are determined based on the sensor readings and the initial estimation weights. User-specific weights are determined by modifying the initial estimation weights using an aggregate force value determined from the obtained sensor readings. The user-specific weights can be used to determine synthesized sensor readings at void locations for the user. The sensor array can be mounted to a carrier device such as a wearable device worn by the user or fitness equipment used by the user.

A multi-functional health monitoring mat which enables the measurement of—but not limited to the following parameters: Weight, Plantar pressure, Bio-impedance for body composition, and Cardiovascular based measurements, such as: Electrocardiogram (ECG), Ballistocardiogram (BCG) from which additional health indicating analytics can be further extracted. The mat will be comprised of 3 separate layers: (1) A Bottom Layer, used for weight measurement, comprising force measurement sensors (2) A Middle Layer, used for pressure measurement, comprising pressure sensors in a matrix, and (3) A Top Layer, used for bio-impedance measurement, comprising conductive sensors, distributed throughout the top layer, enabling random orientation of the feet. In addition, there will be an electronic sub-system to enable communication of data and information from the bath mat to a mobile application. Measurements taken from the mat are transmitted to a software application on a mobile phone and data is used to provide feedback to the user.

There is provided a biological state monitoring system for monitoring biological state of subject on a bed. The system includes at least one load detector and a controller. In a case that the controller determines that body motion is not twitch, the controller ceases to output estimated value of respiratory rate, or outputs first estimated value which is the latest among estimated values obtained in first period, the first period being directly preceding body motion and being determined by the controller to be a period in which subject has no body motion. In a case that the controller determines that body motion is twitch, the controller successively outputs newly obtained estimated values of respiratory rate.

A patient support apparatus comprises a support structure comprising a base and a patient support surface to support a patient. An actuator system facilitates movement of the patient support surface relative to a floor surface. One or more sensors are responsive to changes in position of the patient support surface caused by the actuator system. A controller is operably coupled to the one or more sensors and the actuator system. The controller is configured to operate the actuator system to move the patient support surface and to monitor the movement of the patient support surface by sensing positions of the patient support surface over time. The controller is further configured to identify a frictional load event on the actuator system during movement in a present cycle and associate the frictional load event with a sensed position of the patient support surface in the present cycle.
