Abstract

A portable unit provides location-related data and physiological information to a person. The preferred embodiment includes a GPS receiver, a physiological sensor receiver, a computation unit to determine location-related data from the GPS receiver and a physiological condition from the physiological sensor, and a GPS antenna configured to encircle a body part of the user. As examples, a chest strap, wrist strap, or head strap may carry at least a part of the antenna. The physiological sensor may be a heart rate sensor, an electrocardiograph sensor, or other physiological sensor. The electronics associated with the data processor, GPS receiver or physiological sensor may be contained in an enclosure separate from the antenna, or such components may be built into the body-part-encircling antenna portion.

Claims

1. A portable unit for providing location-related data and physiological information to a person, comprising:

a housing;

a GPS receiver, contained within the housing;

a physiological sensor receiver, contained within the housing and operable to receive a sensor signal from a physiological sensor;

a computation unit, contained within the housing, wherein the computation unit is adapted to determine location-related data from GPS data provided by the GPS receiver, and to determine a physiological condition from physiological data provided by the physiological sensor; and

an antenna, in electrical communication with the GPS receiver, adapted to encircle a body part of the person.

2. The portable unit of claim 1, further comprising a strap adapted to encircle the body part of the person, so as to allow the housing to be supported by the body part of the person, wherein the strap comprises at least part of the antenna.

3. The portable unit of claim 1, wherein the physiological sensor is a heart rate sensor.

4. The portable unit of claim 1, wherein the physiological sensor is supported by the housing.

5. The portable unit of claim 1, wherein the physiological sensor is supported by the body of the person.

6. The portable unit of claim 1, wherein the physiological sensor is an electrocardiograph sensor.

7. The portable unit of claim 1, wherein the antenna is also in electrical communication with the physiological sensor receiver.

8. The portable unit of claim 1, wherein the computation unit is further adapted to show the location-related data and physiological condition on a display supported by the housing.

9. The portable unit of claim 1, wherein the body part is a wrist of the person.

10. The portable unit of claim 1, wherein the body part is a torso of the person.

11. The portable unit of claim 1, wherein the body part is a head of the person.

12. A portable unit for providing location information to a person, comprising:

a headwear item, adapted to be supported on a head of the person;

a GPS receiver, supported by the headwear item;

an antenna, in electrical communication with the GPS receiver, substantially encircling the headwear item so that the antenna substantially encircles the head of the person when the headwear item is supported by the head of the person;

a computation unit, receiving GPS data provided by the GPS receiver, adapted to determine location-related data to the person.

13. The portable unit of claim 12, further comprising a feedback mechanism, wherein the computation unit is further adapted to provide location-related data to the person through the feedback mechanism.

14. The portable unit of claim 13, wherein the feedback mechanism comprises an audio device, supported by the headwear item so as to be audible to the person when the audio device is energized.

15. The portable unit of claim 13, wherein the feedback mechanism comprises a visual display, supported by the headwear item so as to be viewable by the person when the headwear item is supported by the head of the person.

16. The portable unit of claim 12, further comprising a physiological sensor receiver, adapted to receive a physiological signal from a physiological sensor proximate to the body of the person, and wherein the computation unit is further adapted to determine a physiological condition of the person from the physiological data provided by the physiological sensor receiver, and to provide the physiological condition to the person using the feedback mechanism.

17. The portable unit of claim 16, wherein the physiological condition is a current heart rate of the person.

18. The portable unit of claim 16, wherein the physiological condition comprises a cardio-vascular parameter.
