Abstract
Techniques and devices for transmitting data and information via a bus are provided. According to these techniques, data is transmitted in units or frames together with information that is required or useful for one or more of the transmission and the use of the data. If desired, at least some of the units or frames include a time slot within which freely selectable devices can output onto the bus data representing freely selectable information at freely selectable points in time.

1-20. (canceled)
A first device adapted to transmit data to at least a second and third device interconnected via a bus, wherein the first device is adapted to:
- transmit, in units, data and information concerning at least one of a transmission of the data and a use of the data to one or more second devices to which the data does not concern, and one or more third devices to which the data does concern;
- form the units with at least one region defining a given time slot within which the second and third devices output onto the bus specific information and/or data;
- and
- define, in the second and third devices that are configured to output acknowledgement data that acknowledges whether or not the data and information have been received by the second and third devices in a fault-free condition within the given time slot, at least one setting selected from the group consisting of:
- a setting to determine whether and under which conditions the acknowledgement data are to be output within the given time slot;
- a setting to determine which acknowledgement data is to be output within the given time slot;
- and
- a setting to determine at which points in time within the given time slot the acknowledgement data is to be output.

A first device adapted to transmit data between devices interconnected via a bus, wherein the first device is adapted to:
- transmit, in frames, data, and transmission information that concerns at least one of a transmission and a use of the data, from the first device to one or more second devices, to which the data is not intended, and one or more third devices, to which the data is intended;
- form the frames with a time slot within which the one or more second and third devices output onto the bus data acknowledging whether or not the data and the transmission information in a frame have been received by the second and third devices in a fault-free condition within the given time slot;
- and
- determine, in the at least one second device, a setting to determine which of the one or more second devices have to output acknowledgement data within the given time slot.
1 more element
A device adapted to transmit data to at least one second device and at least one third device interconnected via a bus, wherein the device is adapted to:
- transmit, via the bus, at least one frame that comprises data and information concerning at least one of a transmission and a use of the data, from the device to one or more second devices, to which the data is not intended, and one or more third devices, to which the data is intended;
- form the at least one frame such that it indicates a time slot within which the one or more second and third devices will output onto the bus data acknowledging that the data and information in a frame have been received by the second and third devices in a fault-free condition within the given time slot;
- and
- send, to at least one of the one or more second devices and the one or more third devices, at least one setting that indicates whether acknowledgement data is to be output within the given time slot.
1 more element
A first device adapted to transmit data to at least one second device interconnected via a bus, wherein the device comprises:
- means for transmitting, in frames, data from the device to at least one second device together with information concerning transmission of the data;
- means for forming the frames at least partly with at least one region defining a given time slot within which at least one second device can output onto the bus specific information;
- and
- means for receiving from the at least one second device configured to output acknowledgement data, acknowledging whether or not the data from the first device have been received by the at least one second device in a fault-free condition within the given time slot;
- and
- means for sending one or more settings selected from the group consisting of:
- a setting that indicates which second device or devices may output acknowledgement data within the given time slot;
- and
- a setting to determine at which points in time within the time slot the data are to be output.
6 more elements
A system, comprising:
- a bus;
- a first device, at least one second device, and at least one third device coupled to the bus;
- wherein the first device is configured to output, to the bus, at least one frame that includes data intended for the at least one third device as well as information concerning the transmission of the data, wherein the data is not intended for the at least one second device;
- wherein the at least one frame defines a time slot in which the at least one second device and the at least one third device acknowledge receipt of the at least one frame in a fault-free condition;
- and
- wherein the at least one frame further defines at least one setting selected from the group consisting of:
- whether an acknowledgement is to be output within the indicated time slot;
- under which conditions an acknowledgement is to be output within the indicated time slot;
- and
- at what point in time within the give time slot an acknowledgement is to be output.
7 more elements
A system, comprising:
- a bus;
- a first device, at least one second device, and at least one third device coupled to the bus;
- wherein the first device is configured to output, to the bus, at least one frame that includes data intended for the at least one third device as well as information concerning the transmission of the data, wherein the data is not intended for the at least one second device;
- wherein the at least one frame defines a time slot in which the at least one second device and the at least one third device acknowledges receipt of the at least one frame in a fault-free condition;
- and
- wherein the at least one frame further defines at least one setting that causes one or more of the at least one second device and the at least one third device to enter a sleep mode of operation.
