    Abstract: An electromagnetic anti-tipping device uses electromagnets to steady users and prevent falls by persons with impaired mobility and balance. The device's steadying effect is accomplished by magnetically attracting the legs and/or wheels of balance and mobility assisting apparatus (“balance and mobility aid(s)”) to a stationary surface such as a floor which is made of or covered with a magnetically responsive material. In one embodiment, the device's electromagnet attraction to the floor or other stationary surface is actuated when the operator of the device triggers the device's mechanism or sensor by grip or touch. Once actuated, and until deactivation by the user, the device's electromagnet(s) secure the legs or wheels of the balance and mobility aid to the magnetically responsive floor or other stationary surface. The electromagnets are battery-powered.

    Abstract: According to embodiments, techniques for signal processing using multiple signals are disclosed. A first scalogram may be generated from a first signal and a second scalogram may be generated from a second signal. A modified or masked scalogram may then be generated based on the first and second scalograms. The modified scalogram may then be used to determine at least one physiological parameter. In some embodiments, one or both of the first signal and the second signal may be photoplethysmograph (PPG) signals obtained from a pulse oximeter.

    Abstract: According to embodiments, techniques for using continuous wavelet transforms and spectral transforms to identify pulse rates from a photoplethysmographic (PPG) signal are disclosed. According to embodiments, candidate pulse rates of the PPG signal may be identified from a wavelet transformed PPG signal and a spectral transformed PPG signal. A pulse rate may be determined from the candidate pulse rates by selecting one of the candidate pulse rates or by combining the candidate pulse rates. According to embodiments, a spectral transform of a PPG signal may be performed to identify a frequency region associated with a pulse rate of the PPG signal. A continuous wavelet transform of the PPG signal at a scale corresponding to the identified frequency region may be performed to determine a pulse rate from the wavelet transformed signal.
