Patent number: 8174489Abstract: A method and device for providing a dual-sided display device having increased viewability are provided. A display device includes a dual-sided display assembly and a power supply. The dual-sided display assembly includes a first viewable side and a second viewable side. A first electrochromic layer is formed over the first viewable side and a second electrochromic layer is formed over the second viewable side. Each of the first electrochromic layer and the second electrochromic layer are switchable between a substantially transparent state and a substantially reflective state upon application of a switching voltage from the power supply, the state being selected based on an operational configuration of the display device.Type: GrantFiled: March 5, 2008Date of Patent: May 8, 2012Assignee: Sony Mobile Communications ABInventors: Stefan Sorensson, Ola Thorn

Patent number: 7923869Abstract: A power adapter includes a primary side for receiving power from a mains power supply; a secondary side for providing operating and/or charging power, derived from the primary side, to an electronic device connected to the secondary side; presence logic for determining whether the electronic device is connected to the secondary side; and switching logic for turning off the primary side automatically when the presence logic determines the electronic device is not connected. The power adapter thus shuts itself down if no electronic device is attached, and automatically starts itself up when a device is connected to the power adapter and is thus needed. The power adapter may also include voltage detection logic that detects when the device is fully charged. The power adapter also shuts itself down when an attached electronic device becomes fully charged, and automatically starts itself up when the charged state of the electronic device falls below a predetermined level.Type: GrantFiled: July 10, 2008Date of Patent: April 12, 2011Assignee: Sony Ericsson Mobile Communications ABInventors: Fredrik B{dot over (a)}genholm, Stefan Sörensson, Idris Omerovic, Henrik Heringslack

Publication number: 20100245240Abstract: The invention relates to an electronic device and a method for controlling functionality of such an electronic device in relation to a display unit. The electronic device includes a base unit (3); a display unit (2), an orientation sensing arrangement and an orientation determining unit. The display unit (2) has a first surface area and a second surface area (13) joined to each other by a first and second opposite bounding side and is fastened to and movable in relation to the base unit (3). The orientation sensing arrangement comprises a first sensing unit (15) on the display unit (2) and a second sensing unit (16) on the base unit (3), which arrangement detects that the sensing units are able to communicate with each other and indicates this communication. The orientation determining unit then activates selected functionality of the electronic device based on the indication from the orientation sensing arrangement.Type: ApplicationFiled: February 29, 2008Publication date: September 30, 2010Inventors: Henrik Heringslack, Mats Larsson, Stefan Sörensson

Publication number: 20090191737Abstract: A connector for an electric power supply device is disclosed. The connector is arranged to mate a corresponding connector at an apparatus to which the electrical power supply device is arranged to supply electrical power, wherein the connector comprises at least one electrical contact; a housing having a first part arranged grippable by a user when the user connects or disconnects the connector to the device, and a second part slidably arranged with the first part; at least one electrical contact arranged on one of said first or second part, wherein a first force for connecting the at least one electrical contact to the corresponding mating connector is higher than a second force for causing sliding between said first and second parts; and a switch arranged to be actuated based upon relative positions of said first and second parts, wherein said switch is arranged to electrically control connection and disconnection of an electrical power input of the electric power supply device.Type: ApplicationFiled: May 2, 2008Publication date: July 30, 2009Applicant: SONY ERICSSON MOBILE COMMUNICATIONS ABInventors: Stefan SORENSSON, Henrik HERINGSLACK, Fredrik BAGENHOLM, Per Holmberg
