Abstract:
PROBLEM TO BE SOLVED: To provide a method for controlling a highly reliable pedometer based on the use of an inertia sensor and a pedometer for executing the method. SOLUTION: A method for controlling a pedometer includes the steps of: generating a signal (Az) correlated to the movement of a user of the pedometer; and detecting the walking steps of the user (200-225, 300-320) on the basis of the signal (Az). The method moreover envisages the steps of checking whether sequences of detected walking steps (K-2, K-1, K) satisfy the predetermined conditions of regularity (230, 320, 345); updating a total number of valid walking steps (N VT , 265, 325, 350) when the conditions of regularity (230, 320, 345) are satisfied; and preventing the updating of the total number of valid walking steps (N VT ) when the conditions of regularity (230, 320, 345) are not satisfied.

Abstract:
PROBLEM TO BE SOLVED: To provide a pedometer device and a step detection method using the algorithm of the self-adaptive computation of an acceleration threshold. SOLUTION: The pedometer device 1 detects the walking steps of a user on foot, and an acceleration sensor 2 detects vertical acceleration generated during walking steps for counting. A processor 3 is connected to the acceleration sensor 2, and processes an acceleration signal CalAcc relating to acceleration A in order to detect the occurrence of the walking steps, and especially compares the acceleration signal CalAcc with a first reference threshold S+. The processor 3 automatically adapts a first reference threshold S+ as the function of the acceleration signal CalAcc. In particular, the processing unit 3 modifies the first reference threshold S+ as the function of an envelope Env+ of the amplitude of the acceleration signal. COPYRIGHT: (C)2007,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a junction electronic component for a high voltage sensor without problems, such as latch up. SOLUTION: A junction equipment at least comprises a first type semiconductor region 33 and a second semiconductor region 34, which are arranged adjacently to each other, and have first and second conductive types, respectively, which are opposed to each other, and further have first and second bias regions 37, 38, respectively. The equipment is further equipped with a resistor region 35, which has first conductive type, extends from the first semiconductor region 33, and is adjacent to the second semiconductor region 34 so as to form a resistor path between the first and the second bias regions 37, 38.
