  • Publication number: 20230297347
    Abstract: One or more computer processors identify a string within source code associated with a program integrated interface (PII). The one or more computer processors compare the identified string to a string entry comprised in a PII dictionary. The one or more computer processors, responsive to a match between the identified string and the string entry in the PII dictionary, classify the identified string as translatable or non-translatable based on a classification associated with the string entry. The one or more computer processors, responsive to a non-match between the identified string and the string entry in the PII dictionary, classify the identified string as translatable or non-translatable utilizing a hyperplane model trained with a margin (C) derived from unlimited search. The one or more computer processors, responsive to a classified translatable string, translate the classified translatable string.

  • Patent number: 11687134
    Abstract: Cooling devices, such as fans, installed in a computing device can be automatically identified by reading an encoded signal from the cooling device's tachometer signal line. A cooling device can temporarily output an encoded signal in response to a trigger event, such as a power on event (e.g., powering-on of the cooling device). A controller, such as a baseboard management controller (BMC), can receive the encoded signal and decode the signal to determine identification information about the cooling device, such as vendor information and/or model information. The identification information about the cooling device can be stored, logged, output, and/or used to customize the operation of the cooling device.

  • Publication number: 20220146089
    Abstract: An information handling system may include one or more illuminable icons to present information to a user of the system, such as information regarding a status of the information handling system. An illuminable icon may be lit by a plurality of light sources, and light from the plurality of light sources may be diffused across the illuminable icon by a light guide film. Some illuminable icons may have multiple portions that may be separately illuminated to convey different information to a user. An isolation block may prevent light from light sources configured to illuminate one portion of an illuminable icon from illuminating other portions of the illuminable icon. Thus, light for illuminating icons of an information handling system may be diffused and/or blocked to enhance aesthetic appeal of the icons and to prevent user confusion that may result from bleeding of light from one portion of an illuminable icon to another and/or uneven illumination of an icon.
