Abstract: A wireless interface for a diagnostic instrument is provided. The diagnostic instrument includes a communications interface having an external data port. A wireless adapter coupled to the external data port communicates diagnostic data with one or more computing devices. In a single user mode, a computing device can control several diagnostic instruments wirelessly. In broadcast mode, a diagnostic instrument can send a data stream wirelessly to many listening computing devices. Further features, such as safety warning messages, are provided.

Abstract: A user interface for a computing device is provided. The user interface includes a plurality of display elements. A display element includes an active region, a graphical representation, and a textual description. The active region is sized for enabling human finger tip selection of the display element on a touch sensitive display screen. A display module receives coordinate information from the display screen and determines whether the coordinate information corresponds to the active region. When a user touches the active region, an instrument interface module sends a command to a diagnostic instrument. Further features, such as language localization of the textual description, are also provided.

Abstract: A multipurpose multifunctional (M/M) interface device system comprises one or more system ports configured to couple to a system to be diagnosed; one or more diagnostic ports configured to couple to at least one diagnostic system; a set of power management modules configured to provide a full power level and a reduced power level; and a main processor module configured to control communications between the system ports and the diagnostic ports. The main processor module selectively transitions the M/M interface device between a standby mode at the reduced power level and an operational mode at the full power level in response to prescribed criteria. The device is useful in vehicle diagnostics, such as gas analyses, and other applications.
