BACKGROUND
Portable electronic devices are ever increasing in popularity such as for personal entertainment. Such electronic devices are used in a variety of different environments, such as during travel in automobiles or airplanes. While there are many places a person in a traveling vehicle can place a portable electronic device, such as in a pocket of clothing, on a seat, on the floor, on the dashboard, etc., none of these places offer the stability, security, easy access, and visibility that is desirable.
Various electronic device holders have been developed such as for use in a vehicle cup holder during travel. These holders typically require power cables or other connecting cables to be used with the portable electronic device. Such cables extend from the electronic device outside of the holder in an unsightly manner for connection to an electrical system of the vehicle. These cables can be lengthy and in the way such that passengers can get entangled.
Accordingly, there is a need for an apparatus for holding a portable electronic device in a suitable position while traveling in an automobile or airplane that overcomes the foregoing deficiencies.

DETAILED DESCRIPTION
In the following detailed description, embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. It is to be understood that other embodiments may be utilized without departing from the scope of the present invention. The following description is, therefore, not to be taken in a limiting sense.
The present invention is directed to a docking station for holding and interfacing personal portable electronic devices with one or more electrical systems of a vehicle. The docking station provides supporting electronic circuitry to enable a variety of connectivity options for a portable electronic device.
In one embodiment, the docking station is configured to be an insert for a drink cup holder adjacent to an automobile or aircraft seat. In another embodiment, the docking station is configured to be part of an armrest seat, or a table or trim assembly (such as an aircraft drink rail). The docking station can also be retrofitted into existing aircraft seat structures without cutting any new holes.
The docking station can provide connections for a variety of portable device types. For example, the docking station can support a number of commercially available portable wired or wireless electronic devices, such as portable media players (e.g., iPod players, Zune players, and the like), cellular phones, USB drives, video game players, karaoke equipment, as well as other audio and video sources. If a wired portable device is used, the docking station can support a commercially available connector. The docking station also supports native device connectors such as a 30-pin iPod connector.
The docking station, as depicted in the implementations of FIGS. 2-9 discussed below, has the ability to support a portable device in alternate rotations, such as a portrait mode (upright position) or a landscape mode (e.g., turning an iPod or iPhone on its side to show movies). The docking station can be swiveled to rotate a display and controls of a portable device for the best angle. The docking station is easily removable from a cup holder, to support other powered cup holder options such as a monitor arm, or so that the cup holder can be used to support a drinking cup.
In one implementation, the docking station can connect the portable electronic device to an in-flight entertainment (IFE) system of an aircraft in a wired or wireless manner, to transport audio, video and/or transport control signals, and supports either an analog IFE or a digital IFE system. If a digital IFE system is available for use, the docking station can support alternative power strategies like Power over Ethernet. The docking station can provide the capability for interconnection with IFE command and control systems to support remotely controlling the portable device with other IFE control devices. The docking station can also provide the capability to control the IFE system, with a connected portable device running software that will facilitate that control. The docking station supports digital and/or analog connections to an IFE distribution system or local displays and speakers. If the IFE or other display or audio equipment require encoded digital signals, encode circuitry can be implemented in the docking station or cup holder docking interface.
The docking station provides a mechanical interface, such as a printed circuit board, which interfaces the portable electronic device to vehicle electrical systems such as the aircraft IFE system and/or aircraft power. The docking station also supports power and wired or wireless connectivity from the interface to the vehicle. The docking station can be implemented with various standard media connectors, such as component video (e.g., RCA connectors), composite video (e.g., RCA connectors), stereo and surround (e.g., RCA connectors), High-Definition Multimedia Interface (HDMI), headphone jacks, 3.5 mm auxiliary-in jacks, USB ports, and optical fiber. Additionally, the docking station supports the ability to transmit media via wireless standards including, but not limited to, Bluetooth and 802.11x standards such as 802.11N.
The docking station provides integrated power supply conversion such as from typical aircraft power (28 VDC) to power supported by a portable electronic device. For example, the docking station can be powered by existing wiring run into drink cup holders on aircraft for other purposes, such as for powering display monitors.
The docking station of the invention is described in further detail as follows with respect to the drawings.
