An apparatus for determining a non-apparent attribute of an object having a sensor portion with which the object makes contact and to which the object applies pressure. The apparatus has a computer in communication with the sensor portion that receives signals from the sensor portion corresponding to the contact and pressure applied to the sensor portion, and determines from the signals the non-apparent attribute. The apparatus has an output in communication with the computer that identifies the non-apparent attribute determined by the computer. A method for determining a non-apparent attribute of an object.

Disclosed herein are devices, methods and systems for monitoring and detection of pressure on a part of a body of a user. In an embodiment, a device includes a substrate having a contact surface for contacting a user, one or more sacs associated with the contact surface of the substrate, and one or more sensors in communication with the one or more sacs, the one or more sensors adapted to measure changes in pressure in the one or more sacs. The sacs contain a fluidic material configured to transmit pressure. The fluidic material is further configured to be shock-absorbing and pressure-relieving such that the fluidic material is displaceable by an action of the user contacting the contact surface causing the pressure in the fluidic material to be redistributed.

A load measurement device includes an acquisition unit, a first extraction unit, a second extraction unit, and an output unit. The acquisition unit acquires measurement information output from a load distribution sensor that detects a load distribution received from a sole of a subject. The first extraction unit extracts a region having a load value equal to or larger than a first threshold value as a first region based on the measurement information, and detects the first region as a sole region. The second extraction unit extracts a second region having a load value equal to or larger than a second threshold value that is smaller than the first threshold value from a re-extraction target region defined with the first region as a reference, and adds the second region to the sole region. The output unit outputs information related to a load distribution of the sole region.

Systems and methods are disclosed to determine a measure of patient weight using existing medical device sensors, comprising receiving acceleration information of a patient and, if a value of the acceleration information exceeds an activity threshold over a measurement window, detecting patient steps in the measurement window using the acceleration information, determining a patient step rate over the measurement window using the detected patient steps, determining a measure of patient step force for the measurement window, and determining a measure of patient weight using the determined patient step rate and measure of patient step force.

A virtual scene interactive rehabilitation training robot based on a lower limb connecting rod model and force sense information and a control method thereof are disclosed. The thigh, calf and foot of a leg of a human body are equated to a three-connecting rod series-connected mechanical arm. A human body leg gravity compensation model is constructed. The leg posture of a patient is detected by Kinect. An interaction force between a limb of the patient and a rehabilitation robot is detected by a force sensor on the rehabilitation robot. Then, a progressive rehabilitation training method is designed for the model. According to a set weight reduction ratio, the motion of the rehabilitation robot is controlled by judging plantar force data.

A mobility augmentation system assists a user's movement by determining a corresponding electrical stimulation for the movement. A wearable stimulation array includes sensors, electrodes, an electrode multiplexer, and a controller that executes the mobility augmentation system. The sensors measure movement data, and the mobility augmentation system applies a movement model to the measured movement data. The model can determine different electrical actuation instructions depending on the movement stimulated. For example, to stimulate a knee flexion, the movement model output enables a first set of the electrodes to operate as cathodes and a second set of electrodes to operate as anodes. To stimulate a knee extension, the first set of electrodes can be enabled to operate as anodes and a third set of electrodes as cathodes. The user can provide feedback of the applied stimulation, which the system can use to retrain the model and optimize the stimulation to the user.

Systems, devices, and methods are disclosed for the purpose of quantitatively determining the susceptibility of a human subject to injure their Anterior Cruciate Ligament (ACL). A method for determining injury susceptibility scores or risk categories includes determining hip extension angles and knee varus angles during the performance of a stork test and determining hip abduction angles during a squat test. Determination of angles during certain movements may be achieved using various systems and devices, including wearable devices.

In some aspects, a device is disclosed for monitoring load bearing of a foot. The device can include a housing, a transmitter, and a pressure sensor. The housing can be positioned under a foot of a patient and attach to the foot. The transmitter can wirelessly transmit an indication that a portion of the foot is supporting at least a threshold weight. The pressure sensor can wake up from a sleep mode responsive to the portion supporting at least the threshold weight, cause the transmitter to transmit the indication, and return to the sleep mode.

An apparatus and method for inspection of at least one of grass, artificial turf, infill, or dirt, on a surface, using optical photographic images from a camera and three-dimensional (“3D”) depth scans using the camera and one or more laser, to create a mask to distinguish aspects of the surface, so that the surface can be measured and analyzed.
