An ejection seat includes an ejection seat sequencing system. The sequencing system enables time delays to various components of the system, such the drogue parachute, the main parachute, and harness release cartridge. A sequence controller receives data for a parameter, such as airspeed, from at least two sensors. The sequence controller selects a sequence timing delay mode to implement the time delays for the components of the sequencing system. The sequence controller also accesses a lookup table in a database accessible by the sequence controller. The sequence controller uses a delay parameter of the lookup table to modify a time delay within the sequence timing delay mode, as configured by a user.

A system and method for validating that all functions within a time-critical task are resident in RAM is disclosed. This ensures that time-critical tasks are not impacted by having to access slow nonvolatile memory (NVM). The method comprises generating an exception for each transition between RAM-based instruction execution and NVM-based instruction execution, determining whether the transition is acceptable, and saving a fault address if the transition is not acceptable. A transition is deemed to be acceptable if it does not impact the execution of a time-critical function.

The invention relates to the secure transmission of time-critical data within a communication system, the communication system comprising a plurality of local area networks (100), each of which comprises at least one switch (101) and a plurality of terminal devices (102-105), the communication system comprising a control unit (202), which controls the functions of the plurality of switches and terminal devices, and a control network (200), which is assigned to the control unit and is separate from the local area networks. Communication within a local area network is implicitly authorized on the basis of the allocation of the respective terminal device to the same local area network. Each terminal device is assigned a zero trust adapter (121, 131, 141, 151), which acquires status information about the terminal device, forwards the status information to the control unit via the control network for evaluation, and authenticates the terminal device to the control unit and / or a communication partner. The control unit determines a trust score for the terminal device on the basis of the status information and uses rules depending on the trust score for the configuration or permitted communication relationships of the terminal device, respectively.

A storage device reduces power consumption and processes a first command in a low power mode. The storage device includes a controller to process host commands when the storage device is in a fully active state and to enter a deactivated state when the storage device enters the low power mode. An always-on processor on the storage device enters a sleep state when the storage device enters the low power mode. The always-on processor receives a notification of an incoming host command when the storage device is in the low power mode. When the always-on processor determines that the incoming command is a first command, the always-on processor processes the first command and remains in the sleep state. When the always-on processor determines the incoming command is a second command, the always-on processor may activate the controller to return the storage device to the fully active state.

A system is provided for optimizing routes for time-critical messages in a mesh network. For example, a child node in a mesh network can communicate with a root node through any of its parent nodes. The child node is configured to transmit normal data to the root node through a primary route associated with its primary parent. When a time-critical message is to be transmitted to the root node, the child node estimates a round trip time (RTT) for each route between the child node and the root node. The child node selects, among its parent nodes, a parent node having an associated route with the shortest RTT, and transmits the time-critical message to the root node through the selected parent node. After transmitting the time-critical message, the child node transmits additional normal data to the root node by switching back to the primary route.
