摘要:
A mains power adaptor (1) incorporating a fuel cell (5) for providing alternative power to a low voltage portable device when no mains power is available. The adaptor (1) includes electrical pins (4) configured to connect with a mains power supply socket; a power converter circuit (7) having an input coupled to the electrical pins (4) for converting mains power to a lower voltage supply (8); an electrical output (2) of the lower voltage supply (8); and a fuel cell (5) switchably coupled to said electrical output. The adaptor (1) has a fluid connection port (12) for coupling a fluid fuel outlet of a fuel cartridge (not shown) to a fuel inlet of the fuel cell (5) and the fluid connection port (12) is disposed in a face (3) of the adaptor (1) from which the electrical pins (4) extend. A valve of the fuel cartridge is operable by engagement with the electrical pins (4) of the adaptor (1).

摘要:
A computer peripheral device incorporates a fuel cell that may be used to supply power to a computer device coupled to the peripheral device. The peripheral device comprises a housing and circuitry within the housing to provide at least one computer peripheral function. A data interface provides for data transfer to and/or from a computer device. A fuel cell power source is incorporated into the peripheral device. A power interface provides power transfer to the computer device when connected thereto. A power controller is configured to supply power from the fuel cell power source to the power interface for supplying said power to said computer device when connected thereto.
摘要:
A method and a corresponding system for assisting the passage of an entity (10) through successive zones (Zn to z1) to a destination (40) are provided. The method includes the steps of: associating an identifier with the entity; creating a plurality of required incidents for the entity, each required incident having a place reference and a time reference associated with it, the required incidents including a final incident for which the place reference is the destination and the time reference is a predetermined time; at intervals, detecting the presence of the entity in one of said zones and the time of said presence, thereby generating a match; registering correspondences between the matches thus-generated and said required incidents; and generating an alert for the entity when the time reference for a required incident is reached and that incident does not have a corresponding match. The method operates on a pull system whereby earlier events are driven by the requirements of future events. The method allows preventative action to be taken before delays occur and can adjust to deal with variations in local conditions. A preferred embodiment is implemented in a transport hub, where the entities may be passengers, crew or luggage.
