Abstract: In one embodiment, an apparatus includes a mount, a housing, and a sensor. The mount is adapted to be disposed at least partially underneath a shoelace of a shoe, and the housing is adapted to be releasably attached 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, wherein the tongue is adapted to releasably engage the groove when the housing is attached to the mount. The apparatus further comprises 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 separated from the mount. In another embodiment, a method involves providing a housing that houses a sensor that senses motion of a shoe, and 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.

Abstract: In one embodiment, an apparatus comprises a mount, a housing, and a sensor, wherein the mount is adapted to be secured to a shoe, the housing is adapted to be releasably attached to the mount, and the sensor is supported by the housing such that the sensor remains supported by the housing when the housing is separated from the mount. In another embodiment, an apparatus comprises a mount and a motion-sensing device, wherein the mount is adapted to be secured to a shoe, and the motion-sensing device is adapted to be releasably attached to the mount.

Abstract: In one embodiment, an apparatus for monitoring locomotion of a person that can be secured to the person's shoe includes a mounting unit, a housing unit, and a motion-sensing device. The mounting unit is adapted to be secured to an outer surface of the shoe. The housing unit is adapted to releasably attach to the mounting unit. The motion-sensing device is attached to the housing unit such that, when the housing unit is detached from the mounting unit, the motion-sensing device remains attached to the housing unit. In another embodiment, a motion-sensing apparatus includes a circuit board and an accelerometer. The accelerometer has an acceleration-sensing axis, and is mounted on the circuit board such that the acceleration-sensing axis is oriented at an acute angle with respect to a surface of the circuit board. In yet another embodiment, a motion-sensing apparatus includes a housing unit and an accelerometer. The housing unit is adapted to be secured to an instep portion of a shoe.
