摘要

Systems and methods for updating software in a hazard detection system are described herein. Software updates may be received by, stored within, and executed by a hazard detection system, without disturbing the system's ability to monitor for alarm events and sound an alarm in response to a monitored hazard event. The software updates may be received as part of a periodic over-the-air communication with a remote server or as part of a physical connection with a data source such as a computer. The software updates may include several portions of code designed to operate with different processors and/or devices within the hazard detection system. The software updates may also include language specific audio files that can be accessed by the hazard detection system to play back language specific media files via a speaker.

說明書

FIG. 6B shows an illustrative schematic of sub-portions of one of the image portions of NVM 600 according to an embodiment. FIG. 6B shows, for example, the sub-portions of image 0 portion 608. It is understood that the arrangement of image 1 portion 610 may be the same as image 0 portion 608, but one or more of the sub-portions may be different. For example, the audio kit portion for image 0 (e.g., audio for English) may be different than the audio kit portion for image 1 (e.g., audio for Spanish). As shown, image 608 can include header portion 620 (e.g., an ELF header), signature portion 622, manifest portion 624, installer portion 626, audio kit portion 628, first μP portion 630, second μP portion 632, second μP portion 634, third μP portion 636, and fourth μP portion 638.

Each portion can include code and/or data necessary to identify information or perform operations associated with its name. For example, header portion 620 can include header information for identifying the location of image 0 in NVM 600. Signature portion 622 may include proprietary information used for authentication. Manifest portion 624 may specify the contents of image 0. For example, manifest portion 624 may specify the software version and its audio kit language. Audio kit portion 628 may contain code and/or files for enabling playback of speech in a specific language. For example, in one embodiment, audio kit portion 628 for image 608 may include speech files in the English language, whereas an audio kit portion for image 610 may include speech files in the French language.
