Media Authentication Via Physical Attributes Of A Medium
US Patent:
2008025, Oct 16, 2008
Filed:
Apr 13, 2007
Appl. No.:
11/735134
Inventors:
Hiroo Umeno - Seattle WA, US
Assignee:
Microsoft Corporation - Redmond WA
International Classification:
G06F 7/04
US Classification:
726 2
Abstract:
An optical disc is authenticated by measuring physical attributes of the disc. A challenge is presented to the drive comprising the disc. The challenge includes locations on the disc to be used for authentication. The locations are determined each time the disc is to be authenticated. No restriction is placed on the locations on the medium, and no restriction is placed on the number of locations. Locations on the disc are accessed and an answer to the challenge is calculated in accordance with a physical attribute pertaining to the locations. The answer can include an angle between the locations, the physical separation between the locations, an amount of time elapsed between detection of the locations, an amount of time taken to read data between written between the locations, or a number of rotations occurring between detection of the locations. The answer is analyzed to determine the validity of the disc.
Disc Drive Counterfeiting Countermeasure
US Patent:
8181039, May 15, 2012
Filed:
Apr 13, 2007
Appl. No.:
11/735166
Inventors:
Hiroo Umeno - Seattle WA, US
Assignee:
Microsoft Corporation - Redmond WA
International Classification:
G06F 21/00
US Classification:
713193, 380 44
Abstract:
Counterfeiting of optical disc drives used with game systems is prevented by storing an obfuscated authentication key in firmware of the disc drive. Each disc drive can implement a different obfuscation scheme. The authentication key is parsed into components and the components are stored in various locations in firmware of the disc drive. Drive specific software also is stored in the firmware. Remaining locations of the firmware are randomly populated with binary values.
Multi-Stage Power Adapter
US Patent:
2013023, Sep 5, 2013
Filed:
May 14, 2012
Appl. No.:
13/471412
Inventors:
Van Winston Oler - Redmond WA, US
Hiroo Umeno - Seattle WA, US
Hiroo Umeno - Seattle WA, US
International Classification:
G06F 1/26
US Classification:
713300
Abstract:
Multi-stage power adapter techniques are described in which a power adapter for a device is configured to selectively switch between a relatively low power supply and a relatively high power supply. The low power supply may be employed upon initial connection of the adapter to a host device to ensure that the adapter is safe when disconnected and does not supply full power before the device is ready to receive the high power supply. The low power supply may supply enough power for the host device to detect the connection of the adapter and establish initial communication with the adapter. A switch to the high power supply by the adapter may then occur in response to a notification from the host device that indicates the host device is ready for the high power supply. The switch to high power supply enables normal operation of the host device.

Power And Data Connector
US Patent:
8596881, Dec 3, 2013
Filed:
Mar 23, 2011
Appl. No.:
13/070331
Inventors:
Hiroo Umeno - Seattle WA, US
Assignee:
Microsoft Corporation - Redmond WA
International Classification:
G02B 6/38
US Classification:
385 75, 385 53, 439 38
Abstract:
A power and data connector includes a symmetrical planar connection surface, a pair of symmetrical power interfaces, and one or more magnetic attractors. The planar connection surface is at a terminal end of a tapered extension that protrudes from a lip surface of the power and data connector.
Power Connector
US Patent:
8622629, Jan 7, 2014
Filed:
Sep 23, 2013
Appl. No.:
14/034334
Inventors:
Hiroo Umeno - Seattle WA, US
Assignee:
Microsoft Corporation - Redmond WA
International Classification:
G02B 6/38, H01B 11/22
US Classification:
385 75, 385 53, 385 78
Abstract:
A power and data connector includes an extension that protrudes from a planar lip surface. The extension is configured to cooperate with one or more magnetic attractors of an electronic device to hold the power and data connector to the electronic device via magnetic force. A planar connection surface at a terminal end of the extension separately surrounds openings, through which power interfaces extend.
