IEEE 1621-2004 pdf download IEEE Standard for User Interface Elements in Power Control of Electronic Devices Employed in Office/Consumer Environments
1.Overview
1.1 Scope
This standard covers the user interface for the power status control of electronic devices that ordinarypeople commonly interact with in their work and home lives, including, but not limited to, office equipmentand consumer electronics. Key elements are terms, symbols, and indicators.
This standard does not specify maximum power levels, address safety issues, or cover internal mechanismsor interfaces for industrial devices.
1.2 Purpose
The purpose of this standard is to accomplish a siilarity of experience of power controls across allelectronic devices so that users will find them easier to use and be more likely to use power managementfeatures that save energy.
2. Normative references
The following referenced documents are indispensable for the application of this document. For datedreferences, only the edition cited applies. For undated references, the latest edition of the relerenceddocument (including any amendments or corrigenda) applies.
ANSI/VITA 40,Service Indicators Standard.
CIE Technical Report 107. Review of the Official Recommendations of the CIE for the Colours of SignalLights.
3. Definitions and special terms
3.1 Definitions
For the purposes of this standard, the following terms and definitions apply. The Authoritative DictionaryoflEEE Standards Terms /B17’ should be referenced for terms not defined in this clause. In this standardto increase clarity, power states are italicized.
General definitions
3.1.1 basic power state: On, s/eep, and off: Some devices have multiple instances of one or more of thebasic states (e.g., light sleep, deep sleep). Devices need not have any sleep states.
3.1.2 electronic device: An electronic machine, usually a commercial product, that people commonly useand interact with in their work or home life. In this standard, “device is used as a shorthand for “electronicdevice.”
3.1.3 manual power control: An action taken by a user, or by an external device (including networkactivity), to change the power state of the device.
