DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIG. 1, an example of a docking station embodying the invention is shown at 10, adapted to receive a portable computer such as a laptop shown at 11. The docking station 10 has holding means 12 to hold the portable computer 11 in engagement with the docking station 10, in this example displaceable clips to engage the sides of the computer 11. The docking station 10 further has mounting means 13 to mount the docking station 10 in position on the vehicle, and a connection means generally illustrated at 14 to connect the laptop to a subsystem of the vehicle. The connecting element may comprise a physical connection such as that shown at 15 to engage sockets shown at 16 on the back of the computer 11, or may comprise a wireless connection such as an infrared link or a radio link such as Bluetooth. It may be envisaged that the physical connection 15 includes a power connection to engage a power input of the computer 11 and connected to a power supply system of the vehicle such a power connection can power the computer 11 and also recharge a battery of the computer 11. Indeed both a physical connection 15 and a wireless connection 17 could be provided to provide a data connection between the computer 11 and a vehicle subsystem.
A view of a vehicle interior is shown in FIG. 2. In this example, the vehicle 19 has a roof 20 and the docking station 10 is mounted on the underside of the roof 20. The computer 11 is then engaged with the docking station 10 with its screen 18 disposed generally vertically facing rearwardly of the vehicle. So that the display 21 shown on the screen 18 appears in the correct orientation to the occupants of the vehicle, the display 21 is inverted, i.e. rotated through 180° such that it appears the correct way up when viewed by the occupant of the vehicle. The display may be rotated in known manner by a suitable graphics controller of the computer 11. The computer 11 may be instructed to invert the display by operating the user selecting an option, or may be instructed to invert the display as a result of an instruction received from the docking station 10, or it may indeed that the computer be operable to detect that it is inverted and orient the display 21 accordingly.
The docking station 10 is located such that a computer 11 received in the docking station 10 is located between front seats of the vehicle 19 such that the view out of the windscreen is sufficiently unobstructed for the driver to be able to drive the vehicle safely and so the display 18 is viewable by passengers of the vehicle.
With reference to FIG. 3a, when the computer 11 is received in the docking station 10 it permits a broader variety of functions to be offered to a user and lets the computer 11 to interface with other subsystems on the vehicle. In the example of FIGS. 2 and 3a, the computer 11 can interface with an engine management system generally shown at 24, an audio system generally shown at 25, vehicle speakers generally shown at 26 or a navigation system generally shown at 27 or indeed any other subsystem as required such as a mobile phone holder to provide a mobile telephone network connection or indeed any other function as desired. The computer 11 can then display information from the subsystem such as navigation information, information from a trip computer, engine status information such as information that a car component is about to fail and, via the navigation console 27, provide directions to the nearest garage, computer games, play DVDs for the benefit of passengers or indeed provide any other computer function to a user in the vehicle such as email or otherwise. The computer 11 may receive GPS signals, whether from a navigation console or otherwise and may communicate with subsystems of the vehicle via physical electrical connections or via a wireless connection or otherwise. It might be envisaged that the users are provided with appropriate control devices such as a joy pad for gaming or a wireless keyboard or a remote control similar to a television remote control device or otherwise. The computer 11 could directly interface with the car speakers to provide entertainment, or communicate via the audio system as appropriate. On finding a mobile phone connection, it is apparent that the computer 11 can send and receive information and data for any appropriate function and indeed, where the computer is connected to an engine management system 24, can transmit data to the car manufacturer or to a car maintenance centre or otherwise as desired.
In an alternative arrangement as shown in FIG. 3b, the computer 11 is disposed such that the screen 18 faces forwardly of the vehicle and is visible to an occupant of a front seat of the vehicle 19 in a rear-view mirror as shown at 27. The display 25 is then not only inverted, to appear the right way up, but is reversed about An vertical axis of the screen such that the display 21 appears correctly oriented when viewed in the mirror 27. In this way the screen 18 does not provide any obstruction to the forward vision of the driver.
To provide the two orientations shown in FIGS. 3a and 3b, it would be apparent that the docking station 10 could be adapted to provide either orientation. Alternatively, the laptop could be provided with a pair of screens as discussed in our co pending application number (HP50016925).
Although in the present example the vehicle is a car, it will be apparent that the docking station may be provided in any appropriate vehicle and in any suitable position as desired.
The features disclosed in the foregoing description, or the following claims, or the accompanying drawings, expressed in their specific forms or in terms of a means for performing the disclosed function, or a method or process for attaining the disclosed result, as appropriate, may, separately, or in any combination of such features, be utilised for realising the invention in diverse forms thereof.
