Abstract

An apparatus and method for monitoring potentially-cumulative-trauma-syndrome-inducing activities by a wearer is provided. A wearable monitor and wireless transmitter are attached to a body part of the wearer. The monitor monitors activities of the body part of the wearer. The transmitter transmits signals from the monitor to a receiver. The receiver provides the transmitted signals to a processor, which analyzes the received signals and, in response to a determination that a pre-defined threshold has been exceeded, provides feedback to the wearer. The processor is connected via a local-area-network (LAN) connection to a local area-network. Ergonomics personnel can monitor the wearer and set the threshold remotely via the LAN and the LAN connection. Ergonomics personnel can also determine when the monitor is not being worn by the wearer. The monitor is adapted to resist disablement by the wearer.

Claims

1. An apparatus for monitoring potentially-cumulative-trauma-syndrome-inducing activities comprising:

a wearable muscular-tension monitor adapted to be worn substantially on a body part of a wearer;

a wearable wireless transmitter interoperably connected to the monitor wherein the transmitter is adapted to transmit signals generated by the monitor;

a receiver adapted to receive the transmitted signals, wherein the transmitter transmits only when the transmitter is within a pre-defined distance from the receiver; and

a processor electrically connected to the receiver, wherein the processor is adapted to;

analyze the received signals;

determine whether a predetermined cumulative muscular-tension threshold has been exceeded by the wearer; and

provide feedback to the wearer responsive to a determination that the cumulative muscular-tension threshold has been exceeded.

2. The apparatus of claim 1, wherein the receiver is adapted to receive signals from only the transmitter.

3. The apparatus of claim 2, wherein the transmitter and the monitor comprise an integral unit.

4. The apparatus of claim 1, wherein the processor is accessible to a location that is distal from said processor such that ergonomics personnel can set said predetermined cumulative muscular-tension threshold from said distal location.

5. The apparatus of claim 3, wherein the integral unit is battery-powered.

6. The apparatus of claim 4, further comprising a network interoperably connected to the processor, wherein the network permits the ergonomics personnel to remotely set the threshold from said distal location.

7. The apparatus of claim 1, wherein the feedback is provided via a visual display.

8. The apparatus of claim 1, wherein the body part is a wrist of a human being.

9. The apparatus of claim 1, wherein the body part is a back of a human being.

10. The apparatus of claim 4, wherein the monitor and transmitter are adapted to resist disablement by the wearer.

11. The apparatus of claim 1, wherein the monitor is adapted to detect when it is not being worn and is adapted to provide a signal for informing ergonimics personnel the apparatus is not being worn.

12. A method of monitoring potentially-cumulative-trauma-syndrome-inducing activities comprising the steps of:

monitoring, via a wearable monitor, muscular tension of a body part of a wearer;

generating a plurality of signals responsive to the step of monitoring;

wirelessly transmitting, via a wearable transmitter, the plurality of signals;

receiving, by a receiver located within a pre-determined distance from the transmitter, the transmitted signals;

analyzing the received signals;

determining, based on the analyzed signals, whether a pre-determined muscular-tension threshold has been exceeded by the wearer; and

providing feedback to the wearer responsive to a determination that the threshold has been exceeded.

13. The method of claim 12, wherein the receiver only receives signals from the transmitter.

14. The method of claim 12, wherein the transmitter and the monitor comprise an integral unit.

15. The method of claim 12, further comprising the step of setting, prior to the step of monitoring, by ergonomics personnel, the pre-determined threshold for the wearer.

16. The method of claim 12, wherein the unit is battery-powered.

17. The method of claim 12, wherein the threshold is set via a local area network interoperably connected to the processor.

18. The method of claim 12, wherein the step of providing feedback is performed via a display associated with the processor.

19. The method of claim 12, wherein the body part is a wrist of a human being.

20. The method of claim 12, wherein the body part is a back of a human being.

21. The method of claim 12, wherein the monitor and transmitter are adapted to resist disablement by the wearer.

22. The method of claim 12, wherein the monitor is adapted to detect when the wearer is not wearing the monitor.
