    摘要: A method and a ballast for starting a discharge lamp capable of making a rapid start while restraining the overshoot of the light output. The ballast can separately give the initial start time period of applying a maximum power rating to the lamp and the subsequent curve along which the power decreases to a normal power rating of the lamp. A power is varied along a particular run-up curve so as to apply the maximum power rating and subsequently apply the power decreasing to the normal power rating. The run-up curve is derived from a reference curve having a power level decreasing with time. The reference curve has a maximum value above the maximum power rating, and has an inflection point near the maximum power rating to define first and second reference curves above and below the inflection point, respectively. The first reference curve has a first average slope for a first time period from a point of the maximum value to the inflection point. The second reference curve has a second average slope for a second time period which starts from the inflection point and has the same length as the first time period. The second average slope is greater than the first average slope. The run-up curve is a continuous composite curve of the maximum power rating defined by a portion thereof below the reference curve and the remainder of the reference curve defined between the maximum power rating and the normal power rating.

    摘要: A physical activity measuring system analyzes analyzing body motions of a user to accurately determine the exercise intensity. The system includes a portable device which is adapted to be carried by the user and is equipped with a body sensor and an indicator for indication of the exercise intensity. The body sensor senses the user's body motions to give corresponding motion strength. The portable device has a processor which constitutes an exercise calculator which has a predetermined relationship between a default standard deviation of the motion strength and an exercise intensity scale. The exercise intensity calculator collects a time series data of the motion strengths within a predetermined first time frame, obtains a standard deviation of thus collected motion strengths, and converting the standard deviation into an instant exercise intensity within the intensity scale in accordance with the predetermined relationship. The standard deviation with regard to the motion strengths can be well concordant with the exercise intensity, and therefore gives the accurate exercise intensity on a real-time basis.

    摘要: A ballast for a discharge lamp capable of reliably and successfully detecting the end of the lamp life and ceasing the ballast immediately upon detection of the lamp's life end. The ballast includes a power supply providing from a power source a variable power to the lamp, and a power controller controlling the power supply to apply a high voltage for igniting the lamp and subsequently apply a predetermined power for operating the lamp. A lamp life detector is included in the ballast to detect whether or not the lamp comes to a lamp's life end. Also included in the ballast is a supervisor which issues, upon detection of the lamp's life end, a disable signal prohibiting the power supply from lighting the discharge lamp. The power controller provides a detection period of a limited short time period starting from energization of the ballast such that the lamp life detector can detect the lamp's life end and issue a lamp's life end signal only when there is an extinction of lamp within the detection period, and that the supervisor issues, after the elapse of the detection period, an enable signal permitting the power supply to ignite the discharge lamp if the lamp is extinguished after the elapse of the detection period.
