Abstract: Disclosed are systems and methods for a vehicle scanner to automatically execute applications from a removable storage card. The method includes detecting a presence of one or more executable diagnostic requests in removable data storage, and responsive to the detection, transmitting one or more corresponding requests for vehicle diagnostic data to the vehicle via a vehicle interface. Responsive to the transmission, the vehicle scanner receives and processes diagnostic data from the vehicle. The vehicle scanner may store the data back to the removable storage card, or may transmit the data via a wired or wireless interface to a display device. As part of the detection process, the vehicle scanner may first authenticate the removable storage card before executing vehicle diagnostic instructions from the card.

Abstract: A method and system for displaying waveforms generated from input signals received at a common input channel (CIC) of a data acquisition (DAQ) device. An input signal received at the CIC can be displayed as a present-time waveform, and while the input signal is displayed as a present-time waveform, the input signal can be tagged for displaying the input signal as a historical waveform for the CIC. After receiving another input signal at the CIC, a display can be refreshed to display, simultaneously, the historical waveform for the CIC and the other input signal as another present-time waveform for the CIC. The DAQ device can tag the displayed input signal in response to a user pushing a selector device on the DAQ device. The display can display other present-time waveforms with the historical waveform to allow a user to compare input signals received at the CIC.

Abstract: A cable assembly for connecting an electronic device to another electronic device and/or to a signal source. The cable assembly comprises a first connector and a second connector and a plurality of conductors connected between the connectors. The first connector may comprise receptacles for receiving a circuit-interrupter that can open a circuit in the cable assembly when an undesired signal (e.g., a over-voltage signal or an over-current signal) is applied to the cable assembly. The circuit-interrupter may comprise a fuse, such as a non-resettable fuse or a resettable fuse. The first connector may be arranged for connection to an automobile and the second connector may be arranged for connection to an electronic device operable for diagnosing and/or servicing the automobile.

Abstract: Methods, devices, and computer-readable media related to use of a scanner device and access node to repair a device-under-repair are disclosed. The first and second connections can utilize a first communication protocol (e.g., Ethernet or Bluetooth) and the third connection can utilize a different second communication protocol (e.g., OBD-II). In response to receiving a first communication addressed to a first address, the first communication can be sent from the scanner device via the second connection. In response to receiving a second communication addressed to a second address, where the first address differs from the second address, the second communication can be converted to conform to the second communication protocol and the converted second communication can be sent from the scanner device via the third connection.

Abstract: A system and a machine-implemented method for rendering, on a display device, a first data graph concerning data received from a first data source. A second data graph concerning data received from a second data source is rendered on the display device, and superimposed onto the first data graph to generate a superimposed data graph.

Abstract: Peak capture circuitry for measuring a peak value of a waveform characterized by a first portion having a first rate of change and a second portion having a relatively faster rate of change. Peak stretching circuitry stretches a portion of the waveform as a function of time. Digital signal processing circuitry samples an output waveform of the peak stretching circuitry for determining the peak value. Thus, despite any steeply sloped portion, samples can be reliably taken throughout the waveform for calculation of peak value.
