Abstract

An extensible, programmable digital electronic network (14A") originates from a network node (FIG. 1), including a base node microcomputer (90) and a network interface (71C), and is operatively connected to a power supply (61), and at least one separate, network communicating circuit or network node (21), which is connected to at least one application device (21A). Enclosing cases of the network components includes an access sensor (8, 18C, and 22F, respectively) and power storage units (24G, 18B, and 22H, respectively) for fail-safe functions. The application device is programmably controlled by the base node microcomputer, a network security main program (100), a separate circuit or node, and a node security main program (130) to cause the network to selectably effect control of a device, for example, upon loss of network integrity, such that the network and node, respectively, enter programmably secure conditions (125, 155). These conditions include disconnecting the power supply from certain controlled system circuits including vehicle engine starting or ignition (5B'"'"') or one or more nodes causing application devices to function.

Claims

1. A modular, substantially distributed, digital electronic, complex multiple-function, including computing, entertainment, heating system control, and vehicle security functions, substantially independently functioning, network system comprising:

a. a user extensible digital electronic network,

b. a plurality of programmable network communicating nodes, which may connect to communications devices or other computer systems, each of which includes memory and is operatively connected to one or more application devices and

a power supply, and

c. program means to cause said nodes to digitally intercommunicate using said network and, upon the loss or impending loss of network integrity, cause said nodes to substantially actively modify the action of one or more of said devices, including triggering an alarm and automatically initiating a telecommunicated message, whereby said network and said nodes enter, and cause controlled systems to enter, into programmably useful, including secure and safe, conditions.

2. The network system in claim 1 wherein said network is substantially removably, including unpluggably and destructively, accessible to deleterious circumstances, including unauthorized persons, and said loss of network integrity includes the loss or impending loss of said intercommunication, including the detection of access to said nodes or said application devices, and the loss of power, whereby said network and said nodes severally enter, and cause said application devices to enter, into programmably useful, including secure and safe, conditions.

3. The network system in claim 2 wherein said memory includes information about the nodes comprising said network, including the functions, parameters, and locations of said nodes, which said program means programmably modifies when said network is altered, including by the addition of one or more nodes, whereby said network is easy for the operator to alter or extend and, thereby, serve to increase the capacity and concerted activity complexity of said nodes through the gain in synergy due to the number and type diversity of devices and nodes added to said network.

4. The network system in claim 3 wherein each of said nodes and said devices includes a power storage unit which is isolable from said power supply, whereby said network and nodes continue to function without normal power supply in order to enter, and cause said application devices to enter, into programmably useful, including secure and safe, conditions.

5. The network system in claim 4 wherein said power supply is selected from the group consisting of capacitors and batteries whereby said network, said nodes, and said devices can continue to function without an external power source.

6. The network system in claim 5 wherein at least one of said nodes or said application devices includes at least one sensor means to detect physical characteristics and events, including voltage, current, and temperature of said power supply whereby said node can modify the action of one or more of said devices, including other nodes, such that said network and said nodes enter, and cause said application devices to enter, into programmably useful, including safe and secure, conditions.

7. The network system in claim 2 wherein said application device is a switchable connection means which programmably interrupts electrical power to loads, including plant equipment and vehicle starting motors, is electrically attachable to the electrodes or terminals of said power supply, and includes attachment means to fasten said switchable connection means to said electrodes or terminals, whereby important or potentially dangerous equipment can be left unguarded.

8. The network system in claim 7 wherein said switchable connection means is located substantially within an enclosure providing attachment means to connect said switchable connection means to said electrodes or terminals and mechanically fasten said enclosure to appropriate structure associated with said power supply, whereby said network may be installed in a vehicle, including a boat or an aircraft, by attachment to a battery of said vehicle.

9. The network system in claim 8 wherein said enclosure is openable and securely closable and includes at least one sensor to detect the opening of said enclosure, including other physical characteristics and events, whereby said network and said nodes enter, and cause said application devices to enter, into programmably useful, including safe and secure, conditions.

10. In combination, at least one power storage unit with positive and negative electrodes in which said electrodes are substantially located within an internal, substantially enclosed chamber,

a. positive and negative electric terminals,

b. at least one electric connection means interposed severally between said electrodes and said terminals,

c. one or more electric circuits operatively connected to said electrodes of which at least one of said circuits is an extensible electronic network with memory and means to communicate with separate electronics circuits, of which at least one includes memory whereby said circuits and connection means continue to operate without external power and are safeguarded from tampering and exposure.

11. The power storage unit in claim 10 further including

a. at least one external opening which substantially provides access to said chamber and

b. at least one insertable and withdrawable cassette which substantially occupies said chamber and substantially contains said electric circuits, said electronic circuits, said positive and negative terminals, and said electric connections, and means for operatively severally connecting said electrodes to said positive and negative terminals when said cassette is inserted or operatively disconnecting said electrodes from said terminals when said cassette is withdrawn from said power storage chamber whereby cables and operative control can be easily incorporated into said electric and electronic circuits, respectively, in said chamber.

12. The power storage unit in claim 11 further including program means to cause said separate, network communicating, electronic circuit or circuits to communicate with said network circuit and intercommunicate using said network circuit and, by absence of said communication and said intercommunication or either said communication or intercommunication, including through loss of power, effect control of one or more of said electronic or electric devices, whereby the operation of at least one of said electric circuits is programmably modified.
