The human body is capable of a wide range of movement. This movement occurs in the various areas of the body including the spine and extremities. Range of motion refers to the amount of movement that a particular joint or body part can move measured in degrees. Injuries to muscle, ligaments or bone can impair range of motion, which is commonly assessed after an orthopedic injury.

Portable remote patient telemonitoring system using a memory card or smart card
InactiveUS6454708B1Low costIncrease the number ofSurgeryRespiratory organ evaluationSmart cardFull waveform
A system and method for monitoring health parameters and capturing data from a subject. The system is characterized by a cordless, disposable sensor band with sensors for measuring full waveform ECG, full waveform respiration, skin temperature, and motion, and a connector which accepts a memory card or a smart card for storage of the measured data. After a predetermined period of time, such as when the sensor band is removed, the memory card or smart card is removed and inserted into a monitoring device which reads the stored health parameter data of the subject. The monitoring device includes a base station that includes a memory / smart card reader and is connected to conventional phone lines for transferring the collected data to a remote monitoring station. The base station may also capture additional clinical data, such as blood pressure data, and to perform data checks. Subject safety is enhanced by the ability of the base station to compare clinical data, e.g. ECG, against given profiles and to mark events when appropriate or when the base station is programmed to do so. The remote monitoring station allows the presentation and review of data (including events) forwarded by the sensor band. ECG analysis software and a user-friendly graphical user interface are provided to remotely analyze the transmitted data and to permit system maintenance and upkeep. In alternative embodiments, a smart card includes the sensor band's electronics and / or signal transmission circuitry in conjunction with a portable data logger so that the electronics may be reused from one disposable sensor band to the next without limiting the patient's range of movement. The system of the invention has useful application to the collection of subject clinical data during drug trials and medical testing for regulatory approvals as well as management of subjects with chronic diseases.

System and method for providing gyroscopic stabilization to a wheeled vehicle
InactiveUS20100090440A1Improve stabilityLimited abilityRider propulsionOther supporting devicesControl systemPrecession
This invention provides a stabilizing system and method for two-wheeled vehicles that affords the rider no restriction on the full range of movements (banks, leans, etc.) common to bicycles, but that provides greater stability during turns and other maneuvers so that an unintentional bank or tilt (potentially causing a fall) is less likely, even at relatively slow speeds and startup. A rotating mass of predetermined mass-value and radial mass-distribution is provided coaxially with the front axle. The mass is supported on bearings so as to freewheel with respect to the rotation of the front wheel. As such it can be induced to spin significantly faster than the front wheel thereby generating a gyroscopic effect at the front wheel about the axle. This gyroscopic effect influences the steering of the wheel by the rider. Due to precession, the wheel tends to follow any excessive bank by the vehicle, ensuring that the rider can “steer-out-of” an unintended tilt or bank. Likewise, the gyroscopic effect limits the rider's ability to execute excessive steering, thereby preventing jackknife movements. The mass can be an electric-motor-driven flywheel within a shell housing that includes a battery, control system and drive motor. The drive motor engages a surface of the flywheel with a drive tire in a resilient manner to reduce potential damage to the motor.
