Patent number: 7239110Abstract: There is disclosed a system and method for transferring power without requiring direct electrical conductive contacts. There is provided a primary unit having a power supply and a substantially laminar charging surface having at least one conductor that generates an electromagnetic field when a current flows therethrough and having an charging area defined within a perimeter of the surface, the at least one conductor being arranged such that electromagnetic field lines generated by the at least one conductor are substantially parallel to the plane of the surface or at least subtend an angle of 45° or less to the surface within the charging area; and at least one secondary device including at least one conductor that may be wound about a core. Because the electromagnetic field is spread over the charging area and is generally parallel or near-parallel thereto, coupling with flat secondary devices such as mobile telephones and the like is significantly improved in various orientations thereof.Type: GrantFiled: December 1, 2004Date of Patent: July 3, 2007Assignee: Splashpower LimitedInventors: Lily Ka-Lai Cheng, James Westwood Hay, Pilgrim Giles William Beart

Publication number: 20060043927Abstract: There is disclosed a system and method for retaining portable rechargeable devices to recharging stations wherein one or other or both of the recharging station and the portable device are provided with connecting means adapted for temporary releasable connection of the two. This is particularly advantageous when used with recharging stations, which permit the device to be recharged in multiple places on the recharging station, providing a positive means of retaining the device. This is particularly advantageous if the recharging station is to be used in a mobile environment such as a car, or on a wall or ceiling.Type: ApplicationFiled: September 26, 2003Publication date: March 2, 2006Applicant: SPLASHPOWER LIMITEDInventors: Pilgrim Giles Beart, Lily Ka-Lai
