Abstract: The present disclosure relates to systems and devices for measuring motion of a shoe and tension in the shoelace of the shoe.

Abstract: A system for detecting human motion and body balance includes a flexible substrate configured to be positioned in a shoe of a user, a sensor array comprising one or more force sensors positioned on the flexible substrate, and a controller communicably coupled to the sensor array. The controller is configured to receive force data from the sensor array, determine biomechanical characteristics for the user based on the force data, the biomechanical characteristics including at least one of a center-of-pressure, a center-of-mass, or lower extremity angles for the user, and provide an indication of the biomechanical characteristics to the user.

Abstract: Systems and methods for monitoring food intake include an air pressure sensor for detecting ear canal deformation, according to some implementations. For example, the air pressure sensor detects a change in air pressure in the ear canal resulting from mandible movement. Other implementations include systems and methods for monitoring food intake that include a temporalis muscle activity sensor for detecting temporalis muscle activity, wherein at least a portion of the temporalis muscle activity sensor is coupled adjacent a temple portion of eyeglasses and disposed between the temple tip and the frame end piece. The temporalis muscle activity sensor may include an accelerometer, for example, for detecting movement of the temple portion due to mandibular movement from chewing.

Abstract: The present disclosure relates to systems and devices for measuring motion of a shoe and tension in the shoelace of the shoe.

Abstract: In an embodiment, a non-contact chewing sensor is provided. The chewing sensor includes an optical proximity sensor specifically designed to monitor chewing. An IR emitter/receiver pair of the chewing sensor may be positioned over a muscle of a user that is involved in the chewing process such as the temporalis muscle. The IR emitter of the sensor emits IR light onto the surface of the skin covering the muscle where it is reflected. When the user chews, the amount of light that is received by the IR receiver changes due to the activation of the muscle. The amount of light received can be used as a signal to determine when the user is chewing and likely eating.

Abstract: Various implementations of an occupant detection system may be used in a vehicle to detect the presence of a living occupant (human or otherwise) and generate a warning. The warning may be communicated to another person(s) or to other vehicle systems to alert people in the vicinity of the vehicle. The system prevents injury and death to people and pets that may be accidentally within a parked car and unable to egress. The system may be integrated into a new vehicle or housed in a separate device that can be plugged into a power outlet within the vehicle.

Abstract: Various implementations of a patient monitoring assembly may be useful in preventing pressure ulcers, monitoring of air cushion inflation, estimating physical activity and energy expenditure and managing body weight of a patient seated on the assembly. The patient monitoring assembly may be installed on a manual or powered wheelchair, for example, and continuously monitors and provides feedback to the patient and/or caregiver about whether the patient is engaging in pressure relief activities while seated on a cushion of the assembly, whether the patient's activities are in accordance with clinical guidelines for pressure relief, the amount of calories expended over a period of time and the weight and weight distribution of the patient seated on the assembly. The feedback may be provided in substantially real time via an interface on the wheelchair and/or via a remotely located computing device.
