Monitoring activity of a user in locomotion on foot
In one embodiment, an apparatus comprises a mount, a housing, and a sensor. The mount is adapted to be disposed at least partially underneath a shoelace of a shoe. The housing is configured and arranged to be placed in at least first and second states in relation to the mount, wherein in the first state the housing is movable with respect to the mount and in the second state the housing is immovable with respect to the mount. There is a tongue on one of the mount and the housing and a groove on the other of the mount and the housing, the tongue being adapted to engage the groove when the housing is in the second state in relation to the mount and to disengage the groove then the housing is in the first state with respect to the mount. The sensor, which senses motion of the shoe, is disposed within the housing such that the sensor remains disposed within the housing when the housing is placed in the first state in relation to the mount and the housing is moved with respect to the mount.
1. An apparatus, comprising:
a mount adapted to be disposed at least partially underneath a shoelace of a shoe;
a housing configured and arranged to be placed in at least first and second states in relation to the mount, wherein in the first state the housing is movable with respect to the mount and in the second state the housing is immovable with respect to the mount;
a tongue on one of the mount and the housing and a groove on the other of the mount and the housing, the tongue being adapted to engage the groove when the housing is in the second state in relation to the mount and to disengage the groove then the housing is in the first state with respect to the mount; and
a sensor, that senses motion of the shoe, disposed within the housing such that the sensor remains disposed within the housing when the housing is placed in the first state in relation to the mount and the housing is moved with respect to the mount.
2. The apparatus of claim 1 , in combination with the shoe, wherein the mount is disposed at least partially underneath the shoelace of the shoe.
3. The apparatus of claim 1 , wherein the sensor comprises an accelerometer.
4. The apparatus of claim 1 , wherein the sensor comprises an accelerometer and a microprocessor, the microprocessor being configured to process a signal from the accelerometer to determine at least one parameter based on the motion of the shoe.
5. The apparatus of claim 4 , wherein the sensor further comprises a transmitter, coupled to the microprocessor, to wirelessly transmit a signal representing the at least one parameter to a receiving unit.
6. The apparatus of claim 5 , in combination with the receiving unit.
7. The apparatus of claim 1 , further comprising a mechanism adapted to disengage the tongue from the groove when manipulated.
8. The apparatus of claim 7 , wherein a portion of the mount that contacts the shoe is made of a semi-rigid polymer-based material.
9. The apparatus of claim 1 , wherein a portion of the mount that contacts the shoe is made of a semi-rigid polymer-based material.
10. The apparatus of claim 1 , wherein the mount has a curved lower surface that is shaped to conform to an instep portion of the shoe.
11. The apparatus of claim 1 , wherein the mount and housing are configured and arranged such that the housing can be completely separated from the housing when the tongue is disengaged from the groove.
12. A method, comprising steps of:
providing a housing that houses a sensor that senses motion of a shoe;
attaching a mount to an instep portion of the shoe such that at least a portion of the mount is disposed underneath at least a portion of a shoelace of the shoe;
engaging a tongue on one of the mount and the housing with a groove on the other of the mount and the housing to inhibit the housing from moving with respect to the mount; and
disengaging the tongue from the groove and moving the housing with respect to the mount without separating the sensor from the housing.
13. The method of claim 12 , wherein the sensor comprises an accelerometer and a microprocessor, the microprocessor being configured to process a signal from the accelerometer to determine at least one parameter based on the motion of the shoe, and wherein the method further comprises a step of processing the signal from the accelerometer with the microprocessor to determine at least one parameter based on the motion of the shoe.
14. The method of claim 13 , wherein the sensor further comprises a transmitter, coupled to the microprocessor, to wirelessly transmit a signal representing the at least one parameter to a receiving unit, and wherein the method further comprises a step of wirelessly transmitting the at least one parameter from the transmitter to the receiving unit.
15. The method of claim 12 , wherein the mount is free of electronic components.
16. The method of claim 12 , wherein the mount has a curved lower surface that is shaped to conform to an instep portion of the shoe.
17. The method of claim 12 , wherein the mount further comprises a mechanism adapted to disengage the tongue from the groove when manipulated, and wherein the method further comprises a step of manipulating the mechanism to disengage the tongue from the groove so as to enable the housing to be detached from the mount.
