The invention provides a personal tracking system comprising a wireless communication device, a pedometer electrically coupled to the wireless communication device, and an electronic compass operably positioned with respect to the pedometer. The wireless communication device receives readings from the pedometer and the electronic compass to provide position information. A method of tracking a location of a person, a system for tracking the location of a person, and an electronic module for a personal tracking system are also disclosed.

Disclosed is an exercise apparatus for use in accurately and automatically tracking number of steps taken by a user both on and off of an exercise machine. The apparatus comprises a step counter such as a pedometer for counting number of steps taken by a user, the step counter continually counting cumulative number of steps taken in a given time period both while the user is on and off of the exercise machine, the step counter having a first communication means for periodically communicating the current cumulative step count to a console of an exercise machine while the user uses the exercise machine; and, the console comprising, a second communication means for receiving the current cumulative number of steps from the step counter while the user uses the exercise machine. The apparatus may further comprise a data processor, a display and a memory means.

An electronic device (10) comprising a location determining component (12), such as a global positioning system (“GPS”) device, a pedometer (14), and a computing device (16) is operable to determine a distance traveled by a user. The pedometer (14) is operable to sense a step taken by the user, and the location determining component (12), when accessible, is operable to determine a distance between two positions and supply such information to the computing device (16) for continuous calculation of an accurate step size of the user. When the location determining component (12) is inaccessible, the computing device (16) determines the distance traveled using the accurate step size information. In additional embodiments, a housing (132) is provided for storing a location determining component (112), a pedometer (114), and a computing device (116), and an accelerometer (242) is provided for also determining the step size of the user. A computing device (216) is then operable to calibrate the step size of the user as determined by the accelerometer (242).

To carry out step number measurement more precisely even when a walk signal enough to be detected is not obtained. After a fixed noise of a signal detected by an acceleration detecting portion having an acceleration sensor is removed by a filter portion of a counting portion, a walk cycle comparing portion compares a cycle of the resultant signal with a moving average value calculated by a walk cycle calculating portion, and each signal within a predetermined cycle range is counted as the number of steps for one step by a step number counting portion. A signal within a range similar to a cycle n times as large as a predetermined cycle of the signals each beyond the predetermined cycle range is judged as the number of steps for n steps by an extra-regulation step number processing portion and is counted as the number of steps for n steps by the step number counting portion. Data on the number of steps obtained through the counting in the step number counting portion is displayed on a display portion.

The invention discloses a gait counting method and a gait counter. The gait counter can be worn on a wrist or other parts of a body and is used for precisely counting different kinds of gaits of a wearer. The gait counting method comprises the following steps: analyzing an output signal of an acceleration sensor so as to generate two groups of dynamic threshold parameters and a group of dynamic time parameters; when an acceleration output signal change value is greater than a first threshold parameter and spans downwards across a second threshold parameter, performing gait counting analog; comparing the time and corresponding dynamic time parameters in two times of gait counting analog so as to confirm whether next detection is performed or not; performing wrist belt type gait counting characteristic comparison and judging; subsequently judging whether the gait counting analog meets specific counting rule parameters; judging whether the gait counting analog meets corresponding gait rule parameters so as to confirm whether the corresponding gaits need to be counted. By adopting the gait counting method and the gait counter, the wearer can wear the gait counter on the wrist or the other parts of the body to precisely count the different kinds of gaits.

Embodiments of the invention provide a step length estimation method, a pedometer and a step counting system. According to the present invention, when step counting is started, based on each preset duration, according to the human body motion acceleration detected by an acceleration sensor within the preset duration, the motion indexes of the human body within the preset duration are determined, wherein the motion indexes comprise motion step frequency and/or motion intensity; based on the numerical relationship between the pre-statistical motion indexes and the human body step length/height ratio, and the motion indexes, the step length/height ratio is determined; and according to the human body height, the motion step length within the preset duration is estimated; and with the step length estimation method, the pedometer and the step counting system, the problem that the calculation is not accurate when the pedometer uses the step length output by the user to calculate the motion distance is solved in the prior art. The present invention relates to the technical field of computers.

The invention provides a pedometer which aims to enhance the intelligence level of the start of the pedometer. The pedometer comprises a shell, a power supply unit, a man-machine interaction unit, an arousing unit, a wear sensing unit and a control unit, wherein the power supply unit is used for supplying power required by normal operation of the pedometer; the wear sensing unit is used for sensing whether the user has worn the pedometer properly, and sensing a first wear feedback value of the body surface of the user; the control unit is used for comparing the first wear feedback value acquired by the wear sensing unit with a preset threshold; and the arousing unit is used for arousing the pedometer according to the comparison result. The pedometer is automatically aroused to start working by sensing weather has worn the pedometer, thereby enhancing the intelligence level of the pedometer and the user experience.

A pedometer can be equipped with a sensor unit including a sensor for detecting motion by detecting acceleration of a displacement of a main body. Detected acceleration can be compared with a threshold value to determine whether the acceleration corresponds to body motion or to a setting operation. Various setting operations can be performed based on shaking of the pedometer.
