Abstract:
A method for predicting drowsiness is disclosed. By obtaining average heart beat rate values of a driver, and according to the characteristics of the heart beat rate values over a period of time, the method is utilized to determine whether the human being is going to sleep. The method comprises the following steps: detecting a heart beat rate of a driver; calculating a curve of the heart beat rate average during a time interval of X minutes; determining an accumulated period of time during which the slope values of the linear regression equations are smaller than the predetermined slope value Z; determining whether the length of the accumulated period of time is greater than a time threshold T to generate a drowsiness detecting result; and determining whether to raise an alarm based on the drowsiness detecting result.
Abstract:
A method for measuring physiological parameters uses statistical properties, spectrum analysis and feedback mechanisms to remove the signal noise generated by human body movement from a detected physiological signal.
Abstract:
Ophthalmic irrigating solutions are disclosed. The ophthalmic irrigating solution comprises: a) γ-polyglutamic acid (γ-PGA) and/or salt thereof in an amount effective to increase the viscosity of the irrigating solution; and b) an ophthalmically acceptable aqueous vehicle for the γ-PGA and/or salt thereof. Also disclosed is a method of irrigating ocular tissues of a patient, in which the method comprises introducing to the ocular tissues of the patient an ophthalmic irrigating solution comprising γ-PGA) and/or salt thereof in an amount sufficient to irrigate the ocular tissues of the patient.
Abstract:
An intestinal peristalsis detecting device comprises a radio frequency (RF) signal generator, an antenna, and a mixer. After the RF signal generator sends a pulse signal, the antenna receives the pulse signal and emits a pulse electromagnetic wave to an organism. Thereafter, the antenna receives a response pulse electromagnetic wave reflected from the organism to generate a response pulse signal. The mixer couples with the RF signal generator and the antenna to mix the pulse signal and the response pulse signal.
