1. A motion sensing necklace system comprising:
- at least two motion sensors coupled to a necklace, wherein when the necklace is worn by a user, the motion sensors are configured to be located on opposed and offset sides of a neck of the user, and the motion sensors are configured to sense respective different left and right side motion information about a particular motion of the user over a first duration and, in response, generate respective different time-varying left and right side motion profiles, wherein each of the motion profiles includes motion information corresponding to multiple different instances over the first duration, and wherein the particular motion of the user includes a weight shift from one side of the user'"'"'s body to the other;
a microprocessor configured to receive the respective different time-varying left and right side motion profiles, process the received motion profiles together to determine a comprehensive movement profile associated with the user wherein the comprehensive movement profile corresponds to the same particular motion of the user over the first duration that includes the weight shift from one side of the user'"'"'s body to the other, and compare subsequent sensor information with the comprehensive movement profile to provide a comparison result, wherein the subsequent sensor information includes signals later received from the same motion sensors and includes motion information corresponding to multiple different instances over a different second duration; and
a transmitter configured to transmit signals or alerts generated by the microprocessor and based on the comparison result.

Abstract
A motion sensing necklace comprising includes a pendant attached to lower ends of two lanyards. The pendant includes a help button for a user to generate a signal for help, and a battery to power the motion sensing necklace. A neck strap is attached to upper ends of the first and second lanyards. Two motion sensors are located within opposing ends of the neck strap. A microprocessor located within the neck strap processes signals from the motion sensors to determine whether motion has occurred. A transmitter or transceiver located within the neck strap transmits motion detection signals and alerts generated by the microprocessor.

11. A motion sensing necklace comprising:
-
a pendant attached to lower ends of first and second lanyards;
the pendant including a battery to power the motion sensing necklace;a neck strap attached to upper ends of the first and second lanyards; at least two motion sensors located within the neck strap at opposed and offset sides of a neck when the necklace is worn, the motion sensors configured to sense respective different left and right side motion information about a particular motion of a user over a first duration and, in response, generate respective different time-varying left and right side motion profiles, wherein each of the motion profiles includes motion information corresponding to multiple different instances over the first duration, and wherein the particular motion of the user includes a weight shift from one side of the user'"'"'s body to the other; a microprocessor located within the neck strap that processes the respective different time-varying left and right side motion profiles from the motion sensors to determine a user-specific comprehensive movement profile that corresponds to the same particular motion of the user over the first duration that includes the weight shift from one side of the user'"'"'s body to the other, and to determine whether abnormal user motion has occurred by using a comparison of the user-specific comprehensive movement profile and subsequent sensor information to provide a comparison result, wherein the subsequent sensor information includes signals later received from the same motion sensors and each of the signals includes motion information corresponding to multiple different instances over a different second duration; a transmitter located within the neck strap that transmits motion detection signals and alerts generated by the microprocessor; conductive wiring extending through the first lanyard between the pendant and the neck strap, such that the help button and battery are conductively connected to the motion sensor, microprocessor and transmitter; and an antenna embedded within the second lanyard and extending from the neck strap towards the pendant. - View Dependent Claims (12, 17)
