A system for measuring data specific to a subject using gravity comprises a substrate on which a subject lies, the substrate having multiple legs extending from the substrate to a floor to support the substrate, and load sensor assemblies. Each load sensor assembly is associated with a respective leg and comprises a cap configured to receive a load from the substrate, a base configured to provide contact with the floor, the base and cap configured to fit together to maintain alignment of the cap to the base while allowing vertical movement of the cap, a load cell between the base and the cap, one of the base and cap configured to translate the load to the load cell and a printed circuit board that processes and outputs data from the load cell, wherein a combination of all load sensor assemblies receive an entire load to which the substrate is subjected.

Devices and methods for determining item-specific information for single or multiple items on one or multiple substrates are described. The method includes generating multiple sensor multiple dimensions array (MSMDA) data from multiple sensors, where each of the multiple sensors capture sensor data for one or more items in relation to a substrate. For each item, the method includes determining relationships between the multiple sensors based on characteristics of the MSMDA data, determining a location of the item on the substrate based on at least the determined relationships between the multiple sensors, determining an angular orientation of the item on the substrate based on at least the determined relationships between the multiple sensors, and determining a body position of the subject on the substrate based at least the determined relationships between the multiple sensors, the location of the subject, and the angular orientation of the item.

A bed comprises substrate support members, each including a load bearing and a base configured to provide contact with a floor. The load bearing member is configured to move vertically relative to the base, while the base and the load bearing member are configured to fit together to maintain lateral alignment of the base and the load bearing member. A load sensor is positioned between the base and the load bearing member, the load bearing member configured to transmit a load from the substrate to the load sensor. A printed circuit board is in communication with the load sensor. A controller is in communication with the printed circuit board of each substrate support member and is configured to receive and process data output by the printed circuit boards.

A contact detection instrument including a rod, a tip sensor portion that is attached to one end of the rod and is inserted into a living body through a hole, a speaker that, from outside the living body, inputs a sound into a hollow space that is formed in the interior of the rod and the tip sensor portion, and a microphone that, outside the living body, outputs an electrical signal that corresponds to the sound inside the hollow space, with the tip sensor portion including an elastic material that covers the hollow space.

An alignment aid for a golfer includes a handheld device with a direction finding device for determining a target vector (V1) with respect to a sighted target, a sensor device for determining a position vector (V2) as a measure of an instantaneous alignment of the golfer, and a display device. The alignment aid is operable to check an included angle (a) between the target vector (V1) and the position vector (V2) and to output a good signal (G) to the display device upon a successful check of the included angle.

A tracking system for tracking a medical attachment device within a tracking area, the tracking system including a first reflector defining a first tracking region, a medical attachment device having at least one reflector sensor operable to integrate the first reflector, and a processor communicatively coupled to the medical attachment device, the processor operable to determine a distance between the medical attachment device and the first reflector to determine a location of the medical attachment device relative to a subject.

A pair of electronic shoe insoles aids an individual with peripheral neuropathy in walking without falling, despite the user having little or no sensation in her feet. Each insole uses a number of pressure sensors and provides various forms of biofeedback to the user such as auditory, haptic, and vibratory feedback which corresponds to the position of the user's foot on the ground. Vibration feedback is provided through vibration motors disposed against the soles of the user's feet at selected locations which correspond to locations of pressure sensors. This allows for direct neural stimulation of the sole of the foot at three biomechanically appropriate locations. Auditory and haptic feedback are provided through auxiliary devices that the user wears on appropriate parts of the body. Biofeedback transmitted through these mechanisms would correspond to change in foot position as detected by the pressure sensors. The shoe insoles may provide one or more of these forms of feedback, and other types of feedback may be provided by output devices as well. An embedded microcontroller wirelessly connected to a computer, tablet or phone permits an individual to monitor gait performance and to adjust numerous parameters of this biofeedback mechanism, such as time delays and strength of vibration or audio feedback. The device may also include a driving mode in which small variations of pressure on the gas pedal would be conveyed to the user through haptic and auditory feedback, thereby allowing the user to drive.

A training and simulation assembly for the learning of deliberate control of a specified body part by a test subject contains an electrode cap, which has a number of electrodes, and an evaluation unit, which is configured to measure voltages present at the electrodes and to provide measurement results as EEG measurement data. The evaluation unit analyzes the EEG measurement data for the presence of a mental act and to determine a correspondence value, which indicates the correspondence of the EEG measurement data with reference values defined by the mental act. A control unit and a simulation unit are provided. The simulation unit stimulates the body of the test subject at a specified point of the body and/or to trigger a motion. The control unit controls the stimulation unit and the ability to apply an indicating stimulus to the body part by the stimulation unit.
