Improved apparatus and methods of sensing or monitoring body orientation and motion and measuring range of motion (ROM) for use in athletic training and physical rehabilitation and evaluation. The apparatus includes a 3-axis sensor, at least one memory, and at least one processor, and is attachable to an object to be monitored. The 3-axis sensor senses a magnitude of tilt along each of a first, second, and third axis, the memory stores data representing the sensed magnitudes of tilt, and the processor processes the data stored in the memory. In one embodiment, the processor determines an angle between each of the first, second, and third axes and a horizontal plane, and selects the two axes corresponding to the two smallest angles between the three axes and the horizontal plane. The processor then generates an indication of the orientation of the object based upon the sensed magnitudes of tilt along the two selected axes.

Apparatus and methods are disclosed for a virtual locomotion controller user interface and system that combines data obtained from various sensor devices to allow users to control the movements of their representation in a virtual world using sensorimotor responses closely resembling the tasks and actions they would physically perform in the real world. As a result, users can specify an avatar's locomotion style by assuming body postures normally associated with that type of movement, while controlling locomotion speed or displacement through foot forces and / or stepping motions and locomotion direction through foot and body orientation.

An apparatus used for notifying a user of a patient's upper body physical orientation. The apparatus uses an inclinometer that is attached in the region of the patient's upper body to measure the physical orientation of the patient's upper body, which is then transmitted to a display. In one embodiment, the display can be set to display a plurality of alarm conditions. In other embodiments the patient upper body orientation information is transmitted to a processor and then to the nurses' station or to a ventilator. The invention also relates to a method for measuring the physical orientation of a patient, using such an apparatus.

A water survival system and a method are disclosed for detecting the danger of a person drowning in a body of water. The water survival system includes a breast belt and a life jacket. The breast belt has at least one physiological condition sensor affixed thereto while the life jacket has an expandable chamber connected to a compressed gas supply via an activating mechanism. As the compressed gas enters the expandable chamber, the life jacket increases in buoyancy. The life jacket also has a water contact sensor, a global positioning system device, first and second body orientation sensors, a transmitter which is capable of sending a signal to a remote receiver, and a control unit capable of receiving real time signals from each of the sensors and evaluating and comparing the real time signals against corresponding ranges of preset acceptable values to determine if the person wearing the life jacket is in danger of drowning. The control unit is capable of forwarding a signal to both the activating mechanism and to the transmitter when a signal from the water contact sensor indicates the person is in the water and the real time signals from the other sensors are outside of corresponding ranges of preset acceptable values. The signal to the activating mechanism opens the compressed gas supply while the signal to the transmitter is relayed to the remote receiver which sounds an audible alarm.

A wearable device for monitoring and providing real-time feedback about a swimmer's body motion and performance, in particular, body orientation and forward speed, is provided. The device comprises a three-axis accelerometer, optionally a three-axis gyroscope, a memory, and a microcontroller configured to process the sensor input, calculate a swimmer's performance and provide feedback to the swimmer through an output. The output can be an earpiece or a swimming goggle with a digital display.
