Abstract: Methods, apparatuses and systems of monitoring energy expended by an individual are disclosed. One method includes sensing, by a motion sensor, motion of the individual, identifying a plurality of activities performed by the individual over a period of time based on the identified motions, estimating, by a processor, energy expended by the individual for each of the plurality of the plurality of identified activities, and estimating energy expended by the individual by summing the estimated energy expended for each of the plurality of activities.

Abstract: Methods, systems and apparatus for analyzing breathing of a user are disclosed. One method includes sensing motion of a first portion of the user, sensing motion of a second portion of the user, and generating a summed signal by inversely summing the sensed motion of the first portion of the user with the sensed motion of the second portion of the user. A breathing rate of the user is estimated based on the summed signal. Additionally, a breathing pattern of the user can be identified.

Abstract: Methods, systems and apparatus for identifying an activity of an animate or inanimate object are disclosed. One method includes identifying each elemental motion of a sequence of elemental motions of a device attached to the animate or inanimate object. The activity of the animate or inanimate object can be identified by matching the sequence of identified elemental motions of the device with a library of stored sequences of elemental motions, wherein each stored sequence of elemental motions corresponds with an activity.

Abstract: Embodiments of an electronic device apparatus are disclosed. One apparatus includes a housing structure having an inner surface and an outer surface. A plurality of electrical feed-throughs extend through the housing structure from the outer surface to the inner surface. Each of the feed-throughs includes an outer surface cross-section and an inner surface cross-section and a pass through cross-section. The pass through cross-section of the feed-through is located at a portion of the feed-through that extends through the housing structure. The outer surface cross-section is located where the feed-through is exposed on the outer surface, and the inner surface cross-section located where the feed-through is exposed on the inner surface. The feed-through cross-section is less than the outer surface cross-section and the inner surface cross-section.

Abstract: A wearable motion sensing device is disclosed. One embodiment of the wearable motion sensing device includes a motion sensor, and a pendant that is attached to the wearable motion sensing device, wherein the pendant is attached to the wearable motion sensing device at a location of the wearable motion sensor relative to the motion sensor that when worn by a human being, a mass of the pendant urges the motion sensor towards the human being.

Abstract: Methods and systems for location detection are disclosed. One method includes a plurality of base stations of a location system obtaining information about at least one tag associated with the location system. One of the plurality of base stations is designated as a master base station for each tag. Each master base station electro-magnetically transmits beacons to each tag that the master base station has been designated as the master of. Each tag responds to the electro-magnetically transmitted beacons with an acoustic signal that identifies the tag. Multiple of the plurality of base stations, receive the acoustic signal of each tag. A location of each tag is estimated based on times of arrival of each acoustic signal of each tag at each of the multiple base stations, and based on location information of each of the multiple base stations.
