Abstract: A method for energy management in an electrically assisted vehicle includes the steps of determining the quantity of total energy required for a journey and allocating a quantity of electrical energy to the journey and deducing the quantity of human energy required for the journey on the basic thereof, or allocating a quantity of human energy to the journey and deducing the quantity of electrical energy required for the journey on the basis thereof.

Abstract: The invention relates to a power management method for an electrically assisted vehicle, comprising the following steps: a) determining the total amount of power required for a journey; and b) assigning an amount of electric power to the journey and deducing therefrom the amount of human power required for the journey, or assigning an amount of human power to the journey and deducing therefrom the amount of electric power required for the journey.

Abstract: A system for assisting a driver of a biomechanically-driven vehicle having at least one wheel (R), such as a bicycle, includes a device (DET1) for determining the speed of the vehicle, another device (DET) for determining the heading of the vehicle, a magnetometer (M) with at least two measurement axes for supplying data to determine the heading of the vehicle, and a device for supplying information relating to a movement of the vehicle, based on the speed of the vehicle, the slope of the rolling surface, and the heading of the vehicle.

Abstract: A system for managing profile information in a heterogeneous network of devices hosting master and copy data in accordance with a coherence protocol, the master and copy data being associated by way of a first lease, the copy data automatically being invalidated upon expiry of the lease so that the master data may be modified in conformity with the protocol.

Abstract: An agenda planning system operative to assist an entity in scheduling a sequence of events each involving a resource, the system having a planning element operative to liaise with a resource data source associated with a resource, to schedule an event involving said resource, and a profile element operable to process entity profile data to provide entity preference data and to convey the entity preference data to the planning element, whereby the event may be scheduled in accordance with the entity preference data.

Abstract: A set of resources is accessed via a browser of a computer by procuring a bookmark database including a set of bookmark files, each of which is associated with a URI identifying a resource and includes a description of a set of context items. The context of use of the computer is monitored. The current context file having a set of context items is correspondingly updated. From the contents of the current context file, a subset of the bookmark database is computed to derive a subset of bookmarks having a higher relevance to the user. The subset of bookmarks is displayed by the browser.

Abstract: A method of managing profile information in a heterogeneous network of devices is described, including the steps of distributing a user profile among one or more devices in the form of a plurality of profile nodes and administrating read/write operations on the profile nodes according to a coherence protocol, the coherence protocol being adapted to dynamically allocate administrative rights over the profile nodes to the devices, and conditionally cache the profile nodes according to dynamically determined caching rights. Characteristics and/or changes in the structure of the network and/or the devices constituting the network can cause the profile to be dynamically replicated and distributed across the network so that specific profile information is coherent and accessible to corresponding devices in the network. The invention provides a means for securely storing profile data across a disparate network while ensuring coherence and secutiry.

Abstract: A computer system comprising a trust engine for determining a trust level associated with a computer node and a policy engine for setting access requirements to a personal profile, from the computer node, based upon the determined trust level of the computer node and respective sensitivity levels associated with sub-components of the personal profile.
