Activity monitoring device
First Claim
1. A transportation vehicle passenger activity monitoring device for monitoring the activity of a user travelling on a transportation vehicle, 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 a transportation vehicle.

Abstract
A device for monitoring the activity of a user to prevent deep vein thrombosis when travelling on transportation vehicles. 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 a passenger travelling on a journey in a transportation vehicle, the method comprising:
-
providing the passenger with a self contained activity monitoring device comprising a motion sensor to detect motion of the passenger;
a processor that receives motion information from the motion sensor, and an alarm, the activity monitoring device being mounted on the passenger during the journey;defining, on the basis of characteristics of the passenger, 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 journey to differentiate motion attributable to the user performing the defined exercise pattern from the overall pattern of motion detected including the background motion caused by the transportation vehicle; and notifying the passenger, 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)
