System and method for displaying input data on a remote display device
First Claim
1. A method comprising:
- generating first input data from a first input signal received at a data acquisition (DAQ) device, wherein generating the first input data comprises repeatedly generating input data from a respective most-recently received portion of the first input signal, wherein the DAQ device comprises a first buffer that is operable to store two frames of the first input data, wherein the DAQ device comprises a first display for displaying at least a half-frame of the first input data, and wherein the DAQ device is operable in a first display mode and in a second display mode;
wherein, while the DAQ device is operating in the first display mode or the second display mode, repeatedly updating the first buffer to store two frames of first input data, generated from the most-recently received portion of the first input signal, instead of any other generated first input data;
wherein, while the DAQ device is operating in the first display mode, the DAQ device repeatedly providing the first display with at least a half-frame portion of the two frames of first input data stored in the first buffer; and
wherein, while the DAQ device is operating in the second display mode, the DAQ device repeatedly receiving, via a wireless network, a respective request to transmit live data to a remote display device and the DAQ device responsively transmitting, via the wireless network, a respective one frame portion of the two frames of first input data stored in the first buffer.

Abstract
A system comprising multiple devices that are operable when servicing a device-under service is described. A DAQ device is operable to generate input data from input signals received from the device-under-service and to transmit the input data to a display device via a wireless network. The DAQ device comprises multiple buffers to store the input data. One of the buffers stores two frames of the input data, which can be live input data or historical input data. At any one time, a display at the display device visually presents one frame of input data for each respective input channel of the DAQ device. At any one time, a display at the DAQ device visually presents a half-frame of input data for each respective input channel of the DAQ device. Another buffer at the DAQ device can store more than two frames of input data including historical input data.

12. A data acquisition (DAQ) device comprising:
-
one or more input channels operable to receive input signals from a device-under-service; a first buffer operable to store more than two frames of historical input data generated from the input signals received at the one or more input channels; a second buffer operable to store, for each input channel of the one or more input channels, two frames of live input data generated at the DAQ device or two frames of historical input data stored in the first buffer; a first display operable to visually present input data generated at the DAQ device, wherein, when the first display visually presents the input data, the first display visually presents, for one or more input channels of the DAQ device, at least a half-frame portion of the input data stored in the second buffer; and a wireless transceiver operable to receive a request for input data, wherein the request for input data is transmitted to the wireless transceiver from a display device comprising a second display operable to visually present input data generated at the DAQ device, and wherein the wireless transceiver is operable to transmit, to the display device, a respective one-frame portion of input data for one or more of the input channels of the DAQ device. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A display system comprising:
-
a display device operable to visually present input data; a wireless transceiver operable to transmit from the display device a request for the input data to a data acquisition (DAQ) device via a wireless network, wherein the wireless transceiver is operable to receive the input data from the DAQ device via the wireless network; and a user interface operable to receive a selection of whether the requested input data is live input data or historical input data, wherein, when the display device operates to visually present the input data, the display device visually presents one frame of input data for one or more input channels at the DAQ device, and wherein, when the DAQ device operates to visually present input data, a display at the DAQ device visually presents at least a half frame of input data for one or more of the input channels at the DAQ device. - View Dependent Claims (20, 21, 22, 23, 24)
