Abstract

A wristwatch-typed pedometer with wireless heartbeat signal receiving device includes a watch casing with a watch band for fitting to a user'"'"'s wrist, a wireless heartbeat detector for detecting a heartbeat of the user and generating and transmitting a heartbeat signal wirelessly, and a pace signal sensor which is disposed in the watch casing for detecting a pace of the user and generating a pace signal. When a user puts on the wristwatch-typed pedometer and performs exercise, the heartbeat signal from the heartbeat detector is received by a wireless heartbeat receiving circuit of a control circuit and transmitted to a data processing unit. Moreover, the pace signal from the pace signal sensor is transmitted to the data processing unit via a pace signal receiving circuit of the control circuit. The data processing unit calculates and processes, and transmits the heartbeat signal and pace signal to a display unit for displaying.

Claims

1. A wristwatch pedometer comprising:

a watch casing including a watch band for fitting to a user'"'"'s wrist;

a pace signal sensor disposed in the watch casing for detecting the user'"'"'s paces and generating a series of pace signals corresponding thereto;

a data processing unit coupled to the pace signal sensor for calculating and processing the pace signals; and

a speed calculation table memory coupled to the data processing unit for storing a reference table of stride length against speed in paces per second;

wherein based on the pace signals, from the pace signal sensor, the data processing unit calculates and generates a speed of the user in steps per second and then checks the reference table stored in the speed calculation table memory and obtains a corresponding stride length, and thereby calculates an accumulated distance and a walking speed of the user in length per unit time.

2. The wristwatch pedometer as claimed in claim 1, further comprising a setting unit which is coupled to the data processing unit for setting of a stride length to the speed calculation table memory.

3. The wristwatch pedometer as claimed in claim 1, wherein the speed calculation table memory further comprises a formula which is defined by the user and is an expression of relationship between stride length and speed in step per second for calculation of the stride length at a fixed speed.

4. The wristwatch pedometer as claimed in claim 1, further comprising a calorie burned table memory which stores a personal data of the user including sex and weight, a database of calorie consumption for various exercises and a database of calorie consumption at different intensities, and thereby the data processing unit refers to the calorie bunted table memory and calculates a calorie consumption of the user.

5. The wristwatch pedometer as claimed in claim 4, wherein the data processing unit calculates the calorie consumption of the user based on an exercise intensity which is indicated by the speed of the user.

6. The wristwatch pedometer as claimed in claim 1, further comprising a display unit which is coupled to the data processing unit for displaying the accumulated number of paces, accumulated walking distance and walking speed of the user.

7. A wristwatch pedometer comprising:

a watch casing including a watch band for fitting to a user'"'"'s wrist;

a pace signal sensor disposed in the watch casing for detecting an accumulated number of paces of the user and generating a series of pace signals;

a wireless body signal detecting device for detecting a human physiological signal of the user;

a data processing unit coupled to the pace signal sensor for receiving the pace signals and receiving the human physiological signal from the wireless body signal detecting device, the data processing unit calculating and processing the pace signals;

a speed calculation table memory connected to the data processing unit and storing a reference table of stride length against speed in paces per second, the data processing unit calculating a speed of the user in steps per second and accumulated distance based on the pace signals from the pace signal sensor and a corresponding stride length from the reference table to; and

8. The wristwatch pedometer as claimed in claim 7, further comprising a setting unit which is connected to the data processing unit for setting a stride length to the speed calculation table memory.

9. The wristwatch pedometer as claimed in claim 7, wherein the speed calculation table memory further comprises a formula which is defined by the user and is an expression of a relationship between the stride length and the speed in step per second for calculation of the stride length at a fixed speed.

10. The wristwatch pedometer as claimed in claim 7, further comprising a calorie burned table memory which stores a personal data of the user including sex and weight, a database of caloric consumption for various exercises and a database of calorie consumption at different intensities, and the data processing unit refers to the calorie burned table memory and thereby calculates a calorie consumption of the user.

11. The wristwatch pedometer as claimed in claim 10, wherein the data processing unit calculates the calorie consumption of the user based on an exercise intensity which is indicated by the speed of the user.

12. The wristwatch pedometer as claimed in claim 7, wherein the body signal detecting device comprises a wireless heartbeat detecting device for detecting a heartbeat of the user.
