This standard specifies the notation of radiation data and some non-radiation data that is streamed digitally in real-time from a radiation detection instrument to a receiving device (e.g., smartphone or tablet). ISO/IEC 8824-1 Abstract Syntax Notation One (ASN.1) is used for specifying the format of the data to be streamed. The standard addresses both lower-bandwidth transmission, corresponding to instruments that generate data on the order of several kilobit per second (kb/s), and higher-… read more bandwidth transmission. The radiation data consist mainly of raw or unprocessed data, but other data such as precise time, dosimetric data, device parameters and settings applicable to the further display, processing, or analysis of the data may be streamed as well. Data format for commands from the receiving device to the measurement instrument is not part of this standard. This standard does not address data format for visual data (e.g. photos, videos), for radiation imagers or LiDAR (Light Detection And Ranging, or Laser Imaging, Detection, And Ranging). The transmission protocol is not part of the standard, although some general transmission rules recommendations are provided. The subsequent display, processing, and analysis of the radiation data on the receiving device are outside the scope of this standard. The standard does not address the transmission media, receipt, and later transmission of data to a larger and distant network or how the data is used and processed on the receiving device. read less

This standard defines the requirements and test procedures for a [single, multi-] axis ongyroscopic angular [jerk, acceleration, velocity, displacement] sensor. The output is [an analog electrical signal, a digital electrical pulse train] proportional to angular [jerk, acceleration, velocity, displacement]. The electronics are to be considered part of the sensor to the extent specified herein. All parameters specified in this standard refer to the overall sensor output unless otherwise… read more specified. The device will hereafter be referred to as the sensor. read less

This specification defines the requirements and test procedures for a digital accelerometer which utilizes a linear, single-axis, nongyroscopic acceleration sensor with a permanent magnet torquer (forcer) operated in a [ternary pulse mode, pulse-width modulation mode, analog mode with voltage to frequency converter, …]. The electronics are considered to be part of the accelerometer which produces a digital output proportional to sensed velocity changes. The digital accelerometer is hereafter… read more referred to as the accelerometer. With appropriate modifications, this specification may also be applied to force balance nonpendulous accelerometers. read less

This International Standard defines a format for files containing transient waveform and event data collected from power systems or power system models. The format is intended to provide an easily interpretable form for use in exchanging data. The standard is for files stored on currently used physical media such as portable external hard drives, USB drives, flash drives, CD, and DVD. It is not a standard for transferring data files over communication networks. This standard defines a common format for the data files and exchange medium needed for the interchange of various types of fault, test, and simulation data. The rapid evolution and implementation of digital devices for fault and transient data recording and testing in the electric utility industry have generated the need for a standard format for the exchange of time sequence data. These data are being used with various devices to enhance and automate the analysis, testing, evaluation, and simulation of power systems and related protection schemes during fault and disturbance conditions. Since each source of data may use a different proprietary format, a common data format is necessary to facilitate the exchange of such data between applications. This will facilitate the use of proprietary data in diverse applications and allow users of one proprietary system to use digital data from other systems.
