Apple patents involve light sensing device, radio presets, more
Apple patents involving a light sensing device, radio presets between a portable media player and an accessory and remote control signal learning and processing by a host device and accessory have appeared at the US Patent & Trademark Office. Following is a summary of each.
Patent number 20100282953 is for a light sensing device having a color sensor and a clear sensor for infrared rejection. A light sensing device has a first filter to block visible light in a light path. The light sensing device also has a first color sensor and a clear sensor, to detect light in the light path after the first filter. A light intensity calculator computes a measure of the intensity of visible light in the light path, based on a difference between (a) an output signal of the first color sensor, and (b) an output signal of the clear sensor. Other embodiments are also described and claimed. Chris Yu John Tam is the inventor.
Patent number 20100285763 involves communicating radio presets between a portable media player and an accessory. A radio station presets list can include a listing of radio stations associated with a particular location. The portable media device can determine a current location, select a presets list for the current location (or create a new presets list for the location), and communicate the presets list to the accessory. The portable media device can, periodically or upon request from the accessory, update its location and send a new presets list, if available, to the accessory. After the portable media device and the accessory are disconnected, the accessory can resume using its own presets list. The inventors are Michael Ingrasia, Jeffery T. Lee and Brent Schorsch.
Patent number 20100283624 is for a remote control signal learning and processing by a host device and accessory. The invention involves techniques that facilitate the learning and processing of remote control signals by a host device and an accessory. In one set of embodiments, the host device and the accessory can operate in a first mode in which the host device can learn signals from (and thus be remotely operated by) a variety of different remote controls. For example, in some embodiments the host device can learn signals from a remote control that was not specifically designed to interoperate with the host device or the accessory. In another set of embodiments, the host device and the accessory can operate in a second mode in which the host device and the accessory can process learned remote control signals while minimizing the amount of data transferred between the host device and the accessory. Scott Krueger is the inventor.
Patent number 20100282405 is for a media player with machined window undercut and transparent wall disposed therein. A media player comprising a display screen is provided. The media player can include a housing having an opening and an area of reduced thickness around the opening. The media player can also include a transparent wall having a flange. Alternatively, the transparent wall may not require a flange but rather can be a flat, substantially transparent piece of material such as plexiglass or glass. The flange can be adhered to a surface of the area of reduced thickness in order to form a transparent protective cover for the display screen. In another embodiment of the invention, a method is provided. The method can include forming a transparent wall having a stepped edge for placing in an opening of a media player. The method can also include adhering an adhesive to at least one surface of the stepped edge of the transparent wall. The method can include as well using the cutting tool to cut away a portion of the underside of a housing that surrounds an opening in a media player. The method can also include adhering the transparent wall to the housing the adhesive. The inventors are Douglas J. Weber, Pinida Jan Pinida and Stephen P. Zadesky.
