An Apple patent (number 8135891) for a method and system for transferring button status info between a media player and accessory has appeared at the U.S. Patent & Trademark Office.

Here's Apple's background and summary of the invention: "The present invention relates generally to electrical devices and more particularly to electrical devices such as media players that communicate with accessory devices.

"A media player stores media assets, such as audio tracks or photos that can be played or displayed on the media player. One example of a media player is the iPod media player, which is available from Apple Inc. of Cupertino, Calif. Often, a media player acquires its media assets from a host computer that serves to enable a user to manage media assets. As an example, the host computer can execute a media management application to manage media assets. One example of a media management application is iTunes, version 6.0, produced by Apple Inc.

"A media player typically includes one or more connectors or ports that can be used to interface to the media player. For example, the connector or port can enable the media player to couple to a host computer, be inserted into a docking system, or receive an accessory device. There are today many different types of accessory devices that can interconnect to the media player. For example, a remote control can be connected to the connector or port to allow the user to remotely control the media player. As another example, an automobile can include a connector and the media player can be inserted onto the connector such that an automobile media system can interact with the media player, thereby allowing the media content on the media player to be played within the automobile.

"With the introduction of various media types (images and video), communication between a media player and an accessory may be confusing to end users. Furthermore, it may be difficult to determine, if at all, whether information has been successfully transferred between a media player and an accessory. Thus, there is a need for improved techniques to enable manufacturers of electronic devices to exchange information.

"A method, system, and connector interface for transferring status information between a media player and an accessory is disclosed. The method includes determining, by the accessory, when a button event occurs; and transmitting, by the accessory, at least one button status command to the media player, where the one or more button status commands comprise a context-specific button status command and at least one command associated with a particular media type.

According to the method and system disclosed herein, the media player and accessory may utilize a plurality of commands utilized in a variety of environments such as within a connector interface system environment to facilitate the transfer of status information."

Patent number 8135577 is for audio variance for multiple windows.Systems and methods for varying the audio of multiple windows on a personal computer are provided. The windows may overlap in various configurations. These configurations may cause the audio associated with media playing in each media window that is overlapped to be varied in a number of different ways. The audios may be scaled in response to a set of user preferences. Hoyt Fleming is the inventor.

Patent number 8135577 involves methods and apparatuses to provide improved Braille support. A connection to a Braille device is received, and a Braille caption panel that includes a Braille code is displayed to simulate an output to the Braille device. The Braille caption panel can include a text translated to the Braille code.

The Braille caption panel can include a control element. An accessibility service can be automatically launched to provide the output to the Braille device. Eric Taylor Seymour and Reginald Dean Hudson are the inventors.
