Activity monitoring device
First Claim
1. A office worker activity monitoring device for monitoring the activity of a worker in an office environment, the device comprising a carrier adapted for releasable attachment to a user, a motion sensor mounted on the carrier to detect motion of the user;
- a processor also mounted on the carrier that receives motion information from the motion sensor and which differentiates motion attributable to the user performing a defined exercise from the overall pattern of motion detected, and an alarm adapted to be triggered should a time period elapse without the motion attributable to the user performing the defined exercise being detected, wherein the defined exercise and time period are such that the alarm is triggered if the user has not correctly exercised sufficiently frequently to reduce the risk of deep vein thrombosis, and wherein all of the components of the device are self contained on the user such that the device is portable within the office environment.

Abstract
A device for monitoring the activity of a user to prevent deep vein thrombosis when working. The device comprises a carrier (20) for positioning on or adjacent a user, a motion sensor (10) mounted on the carrier (20) and adapted to detect the user performing a predefined motion, processor adapted to filter the motion detected to remove background motion not attributable to the desired exercise and to reset a timer (12) when the predefined motion is detected. An alarm (14) is operated by the processor should the time period elapse without the exercise pattern being detected. The components are all contained in the carrier (20) which is preferably a small container that can be attached to a user'"'"'s trousers or around the limb of a wearer. Failure to undertake the required motion will cause the alarm (14) to be activated, thus notifying the wearer of the omission.

16. A method of preventing deep vein thrombosis in an office worker working in an office environment, the method comprising:
-
providing the worker with a self contained activity monitoring device comprising a motion sensor to detect motion of the worker;
a processor that receives motion information from the motion sensor, and an alarm, the activity monitoring device being mounted on the working during a work period;defining, on the basis of characteristics of the worker, an exercise pattern to be performed, including a frequency time period for its repetition, to reduce the risk of deep vein thrombosis; processing in the processor the motion detected by the motion sensor during the work period to differentiate motion attributable to the worker performing the defined exercise pattern from the overall pattern of motion detected including the background motion caused in the work environment; and notifying the worker, by means of the alarm, if insufficient or incorrect exercise is detected in order that the defined exercise pattern may be performed to reduce the risk of deep vein thrombosis. - View Dependent Claims (17, 18)
