System for evaluating sleeping comfort of bedding system
An evaluation system including a hardware system for collecting real-time data for evaluating sleeping comfort performance of a bedding system is disclosed. The hardware system includes a thermal and moisture comfort measurement system, a thermal and moisture comfort control system, a biomechanical comfort control system, and a biomechanical comfort measurement system. The evaluation system also includes a computational system having a processor and a tactile database, and a portable device. The computational system is configured to receive and process the real-time data from the hardware system, and is communicatively connected to the portable device for transmitting real-time data for evaluating the bedding system and adjusting the hardware system. A mobile application executable on the portable device is configured to collect subjective opinion of the sleeper using questionnaires, and the processor is configured to perform combined analysis of the subjective opinion and the real-time data of the bedding system.
BODY MOTION DETERMINATION SYSTEM
A body motion determination system (100) configured to determine whether or not a subject (S) on a bed (BD) has a body motion includes: a plurality of load detectors (11, 12, 13, 14) each configured to detect the load of the subject on the bed; a respiratory waveform obtaining unit (32) configured to obtain a respiratory waveform of the subject based on a temporal variation of the load of the subject detected by each of the plurality of load detectors; and a body motion determining unit (33) configured to determine whether or not the subject has the body motion based on a comparison between a first threshold value and a standard deviation of the temporal variations in the load of the subject detected by at least one of the plurality of load detectors. The body motion determining unit is configured to compensate the standard deviation to be used in the comparison by an amplitude of the respiratory waveform.
DETECTION SYSTEM, WALKING EXERCISE SYSTEM, DETECTION METHOD AND STORAGE MEDIUM
A detection system includes an acquisition unit, a calculation unit, a determination unit and a correction unit. The acquisition unit acquires measurement information from a load distribution sensor that detects a distribution of a load received from a sole of a subject. The calculation unit calculates a total load value of a sole region corresponding to the position of a sole of one leg of the subject, based on the measurement information. The determination unit determines an action state of the one leg based on the total load value. The correction unit starts to offset the total load value using an offset filter that decreases an offset amount with time elapse, in response to a determination that the action state is a first action state where the total load value tends to increase and is equal to or larger than a preset determination value.
TENSION-TYPE SMART SHOE UNIT CAPABLE OF FOOT-PRESSURE MEASUREMENT, CARBON NANOTUBE ALIGNMENT METHOD, SENSOR OF ALIGNED CARBON NANOTUBES AND MANUFACTURING METHOD THEREFOR, SENSOR USING RADIALLY ALIGNED CNT, AND SENSOR ARRAY UNIT
A sensing portion of the tension type smart shoe unit is arranged to extend across the width of thea sole of a wearer so that foot pressure applied through the sole is exerted thereon, and a connection portion of the tension type smart shoe unit is fixed by connection to a connecting portion of a circuit block. Thus, even when the foot pressure exerted is biased to the left or right while the wearer is walking, only a portion where the pressure is biased is not sensed in contrast with a conventional case in which piezoelectric sensors are mounted, but the sensing portion is deformed, and the magnitude of an electrical output signal corresponding to the deformation is calculated using an equation of a relationship with a load. Consequently, the amount of foot pressure may be precisely measured even with a simple configuration.
Custom foot orthotic and system and method for designing of a custom foot orthotic
A custom foot orthotic and a system and a method for designing of a custom foot orthotic. The method includes: receiving 3D scan data of the patient's foot; receiving plantar pressure scan data of the patient's foot; establishing a desirable pressure distribution; generating an underfoot elevation profile relative to an elevation profile of the patient's foot in the 3D scan data; determining an internal density profile of the resulting foot orthotic 3D model by superimposing the desirable pressure distribution over the resulting foot orthotic 3D model and reducing or increasing density in regions of the foot orthotic 3D model based on the difference between an expected pattern of support and the desirable pressure distribution; and outputting the 3D model of the custom foot orthotic.
Device for leg and foot positioning in a footprint digitalization system
The present invention relates to an apparatus comprising: a seat for a patient; a support platform for the feet of the patient, positioned anteriorly to the seat; an alignment system allowing a patient's leg and its corresponding foot to be aligned in the three space planes in order to determine the tibia correct verticality; a system for properly positioning the foot on the platform including at least turrets able to allow pads to be applied in contact with the talus and/or scaphoid inside the foot and in contact with the calcaneus and/or cuboid outside the foot; a foot measurement system in a neutral position; an automatic real time driving system for properly positioning the leg and foot with numerical indication and direction of the movements to be carried out; a central unit capable for receiving and processing the data detected by the measurement system for footprint digitalization.
ULTRA-SENSITIVE COMPLAINT STRAIN SENSORS
A strain sensor comprising a conductive member having a plurality of elements arranged adjacent to one another, and a non-conductive and elastically deformable material encapsulating the conductive member, wherein, in an equilibrium state, compressive forces cause at least one of the plurality of elements to contact at least a portion of an adjacent element, and wherein, when a strain is applied, a resulting elastic deformation causes at least one of the plurality of elements to space apart from an adjacent element such that the contacted portion decreases or is eliminated. A multi-axis force sensor comprising a sensing array comprising at least two planar sensors arranged radially on a planar substrate in antagonistic pairs, and a compressible member positioned between the substrate and a central portion of the sensing array, the compressible member acting to displace the central portion of the sensing array away from the substrate.
System and non-intrusive method for exercise posture detection
A system and non-intrusive method for exercise posture detection are provided. The system includes a mat, at least one sensor matrix comprising one or more sensors and configured to generate an electrical signal upon making a contact by the user with the mat, a plurality of sensor lines, a plurality of power lines and a processing subsystem. The processing subsystem includes a data acquisition module configured to extract a first set of data, to extract a second set of data; a data processing module to process the first set of data and the second set of data, to concatenate the first set of data and the second set of data to get a final set of data, to compare the final set of data with a pre-defined set of posture data, to determine the posture of the at least one exercise.
DEVICE, SYSTEM, AND METHOD FOR PROMOTING PATIENT COMPLIANCE WITH A PRESCRIBED LOWER EXTREMITY PARTIAL WEIGHT-BEARING REHABILITATION PROGRAM
In one aspect, an electronic device for promoting proper use of a walking aid during lower extremity injury rehabilitation comprises at least one load sensor configured to measure a load on the walking aid. A memory stores rehabilitation program data defining at least one time interval of a rehabilitation period and, for each time interval, a target load for the walking aid during the time interval. A currently operative time interval of the at least one time interval of the rehabilitation period is identified. Data is received, from the load sensor(s), indicative of a dynamic load on the walking aid during a patient step. Based upon the received data, a peak load upon the walking aid during the patient step is determined. A user notification indicating that the peak load is non-compliant with the target load for the walking aid for the currently operative time interval is provided.
