A small wearable recall device is provided to capture images triggered by a combination of a detection of a capture condition (e.g., changes in motion, temperature or light level) followed by a relatively stable period, as detected by an accelerometer. By triggering on the combination of a detected capture condition followed by a detected stability condition, a clearer image of the environment of an interesting event is expected to be captured. The small size of the recall device makes it possible to integrate it into common portable consumer products, such as MP3 players, purses, clothing, hats, backpacks, necklaces, collars, and other human-wearable products.

Method of transmitting data in a distributed system of programmable controls, wherein data are transmitted between data sources and data sinks, both of which represent a respective node in the distributed system, and wherein the respective data sources and data sinks communicating with one another are determined by way of parameters.

According to an aspect of the present invention, there is provided a parallel fieldbus network-based motor control system including: one or more slave modules that control one or more motors and correspond to each of the one or more motors; and a master module that generates command data for controlling each of the one or more motors and transmits the generated command data to each of the one or more slave modules, wherein each of the one or more slave modules includes a basic processor and an auxiliary processor, the auxiliary processor acquires the command data from the master module via a basic network, and supports the acquired command data to be stored in a shared memory and transmitted to the basic processor or transmits the acquired command data to the basic processor via a local network, the basic processor controls the motor corresponding to the corresponding slave module in accordance with the command data acquired from the master module via the basic network, read from the shared memory, or transmitted via the local network or supports to control the motor, and supports result data executed in accordance with the command data to be stored in the shared memory and transmitted to the auxiliary processor or transmits the result data to the auxiliary processor via the local network, and when abnormality occurs in the basic network, the maser module provides the command data to the basic processor or the auxiliary processor via an auxiliary network or a wireless network, and the auxiliary processor provides the result data to the master module via the auxiliary network or the wireless network, or acquires command data for continuing to control the motor corresponding to the corresponding slave mode from the master module and supports the acquired command data to be stored in the shared memory and transmitted to the basic processor or transmits the acquired command data to the basic processor via the local network.

An apparatus for providing a redundant communication within a vehicle architecture is disclosed. The vehicle architecture includes a plurality of commanded units, each being configured to be controlled by redundant communication lines. The apparatus includes at least a first control unit and a second control unit, which are connected by an interlink communication line and which are each configured to: communicate with the commanded units through one of the redundant communications lines; and communicate with each other through the communication lines by controlling at least one of the plurality of commanded units to act as a gateway unit and to forward information between the redundant communication lines.

An automation system has a plurality of subscribers including a first primary unit, first distributor, second primary unit, second distributor, and at least another subscriber unit. First and second transmitting/receiving devices of the first and second distributor are connected via a ring-shaped data bus. In a first mode, the first distributor forwards telegrams received from the first primary unit to the first transmitting/receiving device, and forwards telegrams received by the second transmitting/receiving device to the first primary unit. The second distributor also forwards first telegrams received by the first transmitting/receiving device to the second transmitting/receiving device. In a second mode, the second distributor forwards telegrams received by the second primary unit to the second transmitting/receiving device, and the second distributor forwards telegrams received by the first transmitting/receiving device to the second primary unit. The first distributor also forwards telegrams received by the second transmitting/receiving device to the first transmitting/receiving device.

A communication system includes multiple relay devices and an SDN controller. The multiple relay devices are connected in a ring shape on multiple communication paths via which multiple communication devices communicate with one another. The SDN controller is configured to manage the multiple relay devices. The multiple relay devices each is configured to receive a frame transmitted from the SDN controller and transmit the received frame to multiple adjacently connected relay devices among the multiple relay devices.

An elevator communication system includes a first elevator controller, a second elevator controller communicatively connected to the first elevator controller, a first ethernet bus portion connected to the first elevator controller, a second ethernet bus portion connected to the second elevator controller, and at least one elevator system node communicatively connected to the first elevator controller via the first ethernet bus portion and to the second elevator controller via the second ethernet bus portion.

An architecture for transmitting data within an avionics system fitted to a vehicle, the architecture comprising a first field bus and a first avionics bus. According to the invention, the architecture comprises at least two primary channels each comprising: a primary field interface enabling communication between each primary channel via the first field bus, the field interfaces being interconnected with the first field bus; and a first avionics interface compatible with the first avionics bus. The architecture comprises at least one primary computer provided with a second avionics interface in communication via the first avionics bus with only one first avionics interface among the first avionics interfaces.
