Vehicular dual mode master/slave interface
First Claim
1. A maritime vehicular-to-handheld interface system comprising:
- a communications network or bus hardwired and communicatively coupled to a plurality of vehicular peripheral devices, the peripheral devices including at least a sonar; and
a dual-mode interface device coupled to the communication network or bus, the dual-mode interface device including an interface processor, housing, user interface, display, power supply means, memory storage means, and means to communicatively couple with a handheld computing device, the memory including instructions which when executed by the interface processor enable the dual-mode interface device to switch between at least two operational modes;
i) a slave mode when the handheld computing device is communicatively coupled to the dual-mode interface device, wherein when in a slave mode the interface processor is a peripheral to the handheld computing device, the latter of which serves as a master controller which receives input from a user and which communicates with each of the vehicular peripheral devices, and wherein in the slave mode all data communicated from each one of the peripheral devices to the handheld computing device or from the handheld computing device to any one of the peripheral devices is routed to and passes through the dual-mode interface device, andii) a master mode when a handheld computing device is not communicatively coupled to the dual-mode interface device, wherein when in the master mode the interface processor is a master controller which receives input from a user and which communicates with each of the vehicular peripheral devices;
wherein the handheld device includes one or more application programs which are configured to receive data from and transmit data to one or more vehicular peripheral devices,wherein the interface processor receives software updates retrieved by the handheld computing device from a remote server, andwherein the housing includes a receptacle to releasably retain and electrically couple the handheld device to the interface processor and power supply means.

Abstract
A vehicular interface may include an electromechanical interface between a handheld electronic device and subsystems on a vehicular bus or network. In selected embodiments the interface may operate in a “master mode” when a handheld device, such as a tablet computer or smart-phone, is not inserted therein. In this mode the interface may serve as a master controller and accesses and controls various subsystems on a vehicle (such as engine control subsystems, media controllers, navigation systems, sensors and transducers) as a master controller. In one embodiment, when a tablet device is inserted into the interface, the interface may automatically switch to “slave mode” in which it acts as an adapter or interface between the tablet device and the vehicular subsystems. In this mode of operation the user'"'"'s exclusive interface is through the tablet computer and the tablet computer serves as the master controller for the system.
