Abstract: One or more drumsticks may be optimally balanced using a grip point of the drumstick by calculating a radius of gyration. The radius of gyration is a controlling parameter wherein the radius of gyration correlates with the grip point, which is itself based on a particular gripping style and hand size. Given the radius of gyration, the center of gravity of the one or more drumsticks may be re-located at a point along the drumstick closely aligned to the radius of gyration. The re-location may be performed by adding a weight to the butt end of the drumstick. Balanced drumstick pairs provide optimum performance, control and handling characteristics for a drummer.

Abstract: There is a need to solve a possible system malfunction when a power supply voltage decreases steeply. To solve this problem, a control method is provided for a voltage detection system having an interrupt mode and a reset mode. First and second detection levels are configured. When a power supply voltage is higher than the first detection level, a latch circuit is placed in a first state to enable the interrupt mode. When the power supply voltage becomes lower than or equal to the first detection level, an interrupt signal is generated to change the latch circuit from the first state to a second state and enable the reset mode. A system reset is issued when the power supply voltage becomes lower than or equal to the second detection level in the reset mode.
