An abnormal state detection device includes: an acquisition unit that acquires an image imaging a device that outputs an abnormal state using an LED; an analysis unit that analyzes the abnormal state of the device based on the light emission pattern of the LED in the image, and generates auxiliary information indicating the abnormal state based on the analysis result; and a display control unit that outputs the auxiliary information to a display unit.

An error notification system includes a plurality of data production systems in communication with a monitoring server. Each data production system has a data processor configured to receive input data from a first set of data production systems, process the input data to produce output data, and make the output data accessible to a second set of data production systems. The monitoring server is configured to monitor data transmissions between the data production systems and to identify, for each data transmission, originating and receiving systems. The monitoring server is further configured to map data flow from each originating source system to identify all downstream data production systems. Upon identification of a data error in the originating source system, the monitoring server obtains data error information, assembles a data error notification, and transmits the data error notification to data production systems meeting system notification criteria.

Aspects of the present disclosure relate to techniques for mitigating inadvertent user information collection in telemetry data. In examples, user information is used to evaluate telemetry data associated prior to transmission to a server device. If an instance of user information is identified within the telemetry data, a warning indication is generated. The warning indication may be transmitted to the server device either instead of or in combination with the telemetry data. As a result of the warning indication, the software may be modified to resolve the issue that caused the introduction of the user information into the telemetry data, thereby avoiding future instances of inadvertent data collection. In response to the warning indication, the server may be configured to reject similar telemetry data from other devices, thereby avoiding collecting such data from the other devices. The server device may also use the warning indication to remove or otherwise censor previously collected user information from stored telemetry data.

An underground mining vehicle includes an electric motor for driving the vehicle, a rechargeable battery for supplying electric energy to the electric motor and a charging system for recharging the rechargeable battery. A control unit is configured to control an operation of the charging system for controlling the recharging of the battery. The control unit is configured to have a number of selectable recharging modes (FRM, SLRM, SERM) and to control the recharging of the battery according to the selected recharging mode (FRM, SLRM, SERM). The vehicle also has a transmitter controlled by the control unit for sending a status notification about an automatic change from a recharging mode to another recharging mode to an operator remote terminal device of an operator of the vehicle.

A diagnostic system is provided and includes a plurality of processors configured to receive data acquired by a sensor. A first processor can execute a safety function that determines a plurality of sensor measurement from the received data, compares selected sensor measurements to predetermined alarm set points, and determines a safety function output for the selected sensor measurements based upon the sensor measurement comparison. A second processor can determine a shadow function output corresponding to the safety function outputs during different respective portions a diagnostic interval. The shadow function output can be configured to replicate the safety function output under conditions where the safety function output is free from error. A third processor can be configured to validate the safety function output by comparing the safety function output to its corresponding shadow function output and outputting a condition based upon the validation comparison.

An information processing system includes a failure information obtaining unit, a handling method definition holding unit, in each of which a handling method to be executed for a failure possible in the monitoring target system is described, a selection unit selecting a handling method definition corresponding to the failure occurred in the monitoring target system, an execution unit performing a handling process, a handling result determination unit determining whether a result of execution of the handling process by the execution unit is a predetermined result, and an output unit, if the handling result determination unit determines that the result of the execution is the predetermined result, outputting information indicating an operator need not perform a handling process and, if the handling result determination unit determines the result of the execution is not the predetermined result, outputting information indicating that the operator needs to perform a handling process.

Methods, systems, and devices for a memory device with status feedback for error correction are described. For example, during a read operation, a memory device may perform an error correction operation on first data read from a memory array of the memory device. The error correction operation may generate second data and an indicator of a state of error corresponding to the second data. In one example, the indicator may indicate one of multiple possible states of error. In another example, the indicator may indicate a corrected error or no detectable error. The memory device may output the first or second data and the indicator of the state of error during a same burst interval. The memory device may output the data on a first channel and the indicator of the state of error on a second channel.

Described herein are systems and methods for fault tolerance in a network cloud environment. In accordance with various embodiments, the present disclosure provides an improved fault tolerance solution, and improvement in the fault tolerance of systems, by way of failure prediction, or prediction of when an underlying infrastructure will fail, and using the predictions to counteract the failure by spinning up or otherwise providing new component pieces to compensate for the failure.

In a distributed control system, when the determination that an error has occurred is made as a result of comparison of correct connection information retained in a storage unit and connection information of an actually connected control object device or terminal communication device by a comparison unit, a central computation device outputs a display signal of an abnormal part to a display device, and the display device displays the abnormal part on the basis of the display signal. A distributed control system and an automatic analysis device provided with the same, and an automatic analysis system are thereby provided, whereby an erroneous connections or defects can be more easily and reliably detected than in the prior art, even when a plurality of control boards are distributedly arranged in the same device.

A method for lighting a backplane lamp of multiple NVMe hard disks is provided. The method includes: transmitting a VPP address to the backplane in a cyclic manner by the controller, and analyzing the address transmitted by the controller by a programmable logic device of the backplane after a data stream transmitted by the controller is received; transmitting, by the controller, hard disk lamp lighting information of a corresponding disk position to the programmable logic device of the backplane, if a VPP address analyzed by the backplane is the same as the VPP address transmitted by the controller; and performing logical conversion on the hard disk lamp lighting information, to convert a serial data stream on the VPP signal wires into a parallel signal, lighting a backplane lamp at a corresponding port, and uploading information of a position of the hard disk to the controller.
