Intelligent roadside unit
The present disclosure provides an intelligent roadside unit. The intelligent roadside unit includes: a radar configured to detect an obstacle within a first preset range of the intelligent roadside unit; a camera configured to capture an image of a second preset range of the intelligent roadside unit; a master processor coupled to the radar and the camera, and configured to generate a point cloud image according to information on the obstacle detected by the radar and the image detected by the camera; and a slave processor coupled to the radar and the camera, and configured to generate a point cloud image according to the information on the obstacle detected by the radar and the image detected by the camera, in which the slave processor checks the master processor, and when the original master processor breaks down, it is switched from the master processor to the slave processor.
Noise estimation method, non-transitory computer-readable storage medium, and noise estimation apparatus
A noise estimation method includes decomposing a first matrix in which values of elements are represented by binary values into a coefficient matrix and a basic matrix, and estimating an element including noise among elements of the first matrix based on a result of comparison between a second matrix obtained by combining the coefficient matrix with the basic matrix and the first matrix.
METHOD FOR MONITORING AN ENGINE CONTROL UNIT
Methods are provided for supervising a motor control unit with at least two separate channels, each of the two channels including at least: means for executing a given application task AS, the application task AS including a plurality of successively executed computations between which latency periods elapse; a first component capable of performing the computations; a second component capable of storing data; the application tasks AS of the channels being capable of communicating. The method comprising includes the following steps: a) detecting a latency period; b) performing, during this latency period, an operating state test of at least one of the components; and c) determining a state of the component corresponding to a failure state or a healthy state.
Method for controlling operation of a medical device in a medical system and medical system
A method for controlling operation of a medical device in a medical system having a medical device, a communication device including a remote control for the medical device, and a safety device adapted for data communication with the communication device. Input data is provided and processed by a first calculation to thereby provide a first calculation result. The input data is processed by a second calculation executed separately from first calculation to thereby provide a second calculation result. The first and second calculation results are compared. When the first and second calculation results are found equal, remote control of the medical device by a medical device application running on the communication device is allowed. When the first and second calculation results are found not equal, the medical device application running on the communication device for remote control of the medical device is prevented.
SYSTEM AND METHOD FOR PROTECTING GPU MEMORY INSTRUCTIONS AGAINST FAULTS
A system and method for protecting memory instructions against faults are described. The system and method include converting the slave instructions to dummy operations, modifying memory arbiter to issue up to N master and N slave global/shared memory instructions per cycle, sending master memory requests to memory system, using slave requests for error checking, entering master requests to the GM/LM FIFO, storing slave requests in a register, and comparing the entered master requests with the stored slave requests.
Apparatus and methods for allocating and indicating engine control authority
A control apparatus includes a first controller configured to generate control signals for controlling an engine or other machine, a second controller configured to generate the control signals for controlling the machine, a transfer circuit, and an arbiter circuit. The transfer circuit is coupled between the machine and the controllers, and is configured to switch from a first state, where the transfer circuit passes the control signals from the first controller to the machine, to a second state, where the transfer circuit passes the control signals from the second controller to the machine, responsive to receiving a first failure signal from the first controller. The arbiter circuit includes three (or more) arbiters, and is configured to control the transfer circuit from the first state to the second state responsive to any two of the three arbiters generating second signals indicative of failure of the first controller.
Operation of I/O in a safe system
A module health system includes a module health circuit comprising a hardware register that is set to a first value in response to the system starting, an application register that is set to the first value in response to the system starting and a watchdog timer register that is set to the first value in response to the system starting. The system further includes a power on self-test that determines whether the system has passed a plurality of tests and that selectively sets the hardware register to a second value based on the determination, an external software application that determines whether a safety critical system is healthy and selectively sets the application register based on the determination, a watchdog timer application that selectively sets the watchdog timer register, a central processing unit that determines whether to de-assert a module health signal.
MONITORING DEVICE, FAULT-TOLERANT SYSTEM, AND CONTROL METHOD
A monitoring device is mounted in each of a plurality of operational systems constituting a fault-tolerant system. The plurality of operational systems have an identical configuration including a processor system. The monitoring device includes a processor. The processor executes instruction to read data from a predetermined storage area in a memory of an accessory device to be monitored, connected to the processor system. The processor further executes instruction to compare the read data with reference data held in advance. The processor further executes instruction to separate the processor system connected to the accessory device to be monitored from the fault-tolerant system when the read data is different from the reference data.
SAFETY MONITORING DEVICE, NETWORK SYSTEM AND SAFETY MONITORING METHOD
A safety I/O module (10) disposed between a network (NW) and a target device (20) is provided. The safety I/O module (10) includes MCUs (121, 122). Further, the each of the MCUs (121, 122) includes a CPU (123) and an RTOS accelerator (124) configured to perform a process for switching a task executed by the CPU (123) and a process for starting the task.
METHOD AND APPARATUS FOR PROVIDING INCREASED STORAGE CAPACITY
Certain embodiments may relate to providing increased storage capacity. For instance, a memory storage device may include a motherboard with an external communication interface. The memory storage device may also include a multiple solid-state drives coupled to the motherboard in communication with the external communication interface. Each of the plurality of solid-state drives may include a respective storage controller to manage the distribution of data during a write or read operation to a combination of a primary storage allocation and a redundant storage allocation. The redundant storage allocation may be included in the combination in response to detecting an error condition associated with at least a portion of the primary storage allocation.
