Systems and methods for determining a colorimetric value from color measurements for multiple ambient color sensors which for each color measurement, in various approaches, select a lighting cluster similar to the color measurement and determine whether the color measurement is valid or invalid based on a calculated similarity between the color measurement and the selected lighting cluster, calculate a weight for the color measurement for combination with other color measurements based on the calculated similarity between the color measurement and its selected lighting cluster, determine whether the color measurement is valid or invalid based on perceptual color space distances for the color measurement for multiple reference light sources, and/or calculate a weight for the color measurement for combination with other color measurements based on the perceptual color space distances for multiple reference light sources.

Use of multiple calibrated ambient color sensor measurements to generate a single colorimetric value

A power and data connector includes an extension that protrudes from a lip surface. The extension is configured to mate with an electronic device. A connection surface at a terminal end of the extension separately surrounds openings, through which power interfaces extend.

Power connector

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.

Multi-stage power adapter configured to provide a first power level upon initial connection of the power adapter to the host device and a second power level thereafter upon notification from the host device to the power adapter

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.

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.

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.

Disc drive counterfeiting countermeasure

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.
