Methods are disclosed for assessing the condition of a cartilage in a joint and assessing cartilage loss, particularly in a human knee. The methods include converting an image such as an MRI to a three dimensional map of the cartilage. The cartilage map can be correlated to a movement pattern of the joint to assess the affect of movement on cartilage wear. Changes in the thickness of cartilage over time can be determined so that therapies can be provided. The amount of cartilage tissue that has been lost, for example as a result of arthritis, can be estimated.

Techniques for providing friction-free transactions using geolocation and user identifiers are described herein. These techniques may ascertain a user's location based on a location of a mobile device. A transaction between the user and a merchant may be completed with zero or minimal input from the user based on the geolocation of the mobile device and the user identifiers. In some implementations, a transaction initiated earlier is completed when the mobile device arrives at the merchant. Additionally, a parent-child or similar relationship may be established between multiple devices. Security on the mobile device based may be provided by biometric identification and calculation of variance from regular movement patterns. Advertisements may be sent to the mobile device based on bids from merchants near to the mobile device.

The present invention relates to systems and methods for monitoring patient support exiting and initiating a response. Movement data is accessed from sensors (e.g., cameras) that are monitoring a patient resting on a support platform. A motion capture pattern summary is generated from the accessed movement data. The motion capture pattern summary is compared to one or more movement pattern data sets in a library of movement pattern data sets. It is determined that the motion capture pattern summary is sufficiently similar to one of the one or more movement pattern data sets in the library of movement pattern data sets. From the determined similarity it is determined that the patient is attempting to exit the support platform. Remedial measures are initiated to prevent the detected platform support exiting attempt.

A method, system and a computer program product for accurately predicting an output motion from a database of motion data based upon an input motion scenario are provided. A motion database is searched to find relevant existing motions. The selected motions, referred to as “root motions,” most likely do not meet exactly the input motion scenario, and therefore, they need to be modified by an algorithm. This algorithm derives a parametric representation of possible variants of the root motion in a GMP-like manner, and adjusts the parameter values such that the new modified motion satisfies the input motion scenario, while retaining the root motion's overall angular movement pattern and inter-joint coordination. The embodiment of the invention can accurately predict various human motions with errors comparable to the inherent variability in human motions when repeated under identical task conditions. The motions may be human or non-human such as other living creatures or robot motions.
