Abstract: A wearable air purification system having a wearable support configured to be supported on a user's head. The wearable support is attached to an air delivery mask which delivers a flow of air to an air delivery region. A motor for driving the flow of air to the air delivery region is mounted on the wearable support, or on the air delivery mask, and an air filter for purifying the flow of air is mounted on the wearable support, or on the air delivery mask. Each end of the air delivery mask is moveably connected to the wearable support so that the wearable support is able move with respect to the air delivery mask from a deployed position to a stowed position. The volume envelope of the wearable air purification system is larger in the deployed position than in the stowed position.

Abstract: A wearable air purifier including a headgear; an air purifier assembly, the air purifier assembly configured to generate a filtered airflow from an outlet aperture thereof; and a nozzle assembly connected to the headgear by a hinge assembly. The nozzle assembly includes an inlet aperture for receiving the filtered airflow from the outlet aperture of the air purifier assembly and an air outlet for emitting the filtered airflow from the nozzle assembly. The hinge assembly is configured such that the nozzle assembly is movable relative to the headgear between first and second configurations, filtered airflow is emitted from the air outlet in the first configuration and filtered airflow is not emitted from the air outlet in the second configuration.

Abstract: A capability progress modeling component for determining the progress of adoption of an on-demand capabilities model by an organization, the deployment progress component comprising: a completion state descriptor component for receiving inputs from an entity describing a current state, a target state and a modeled state for the organization; and a state comparator component for comparing the current state and modeled state with the target status to derive a set of parameters, the state comparator component analyzing the set of parameters to determine deviation points indicating capability areas requiring attention in order for the organization to progress to an on-demand capabilities model.

Abstract: Described is a communications system in which messages may be processed using public key cryptography with a private key (SKu) unique to one or more users (150). The system comprises a server means (130) adapted for data communication with a client (110) via a network (100), the server means (130) comprising first data storage means in which is stored in a secure manner a private key for the or each user, the private key being encrypted with a key encrypting key. The server means further comprises second data storage means in which is stored applet code executable on the client. The server provides the applet code to the client via the network in response to connection of the client to the server via the network.
