The mobile device can include a display and be configured to receive the accessory output data from the isolated test block and to present a display based at least on received accessory output data. The accessory output data received by the mobile device can be electrically isolated from the accessory to provide protection to a device user and the mobile device.
Systems can include a test and measurement tool configured to generate measurement data, and imaging too configured to generate image data, and a processor in communication with the imaging tool and the test and measurement too. The processor can be configured to receive image data from the imaging tool and, if the image data satisfies one or more predetermined conditions, trigger the test and measurement tool to perform one or more corresponding operations. Similarly, the processor can receive measurement data from the test and measurement tool and, if the measurement data satisfies one or more predetermined conditions trigger the imaging too to perform one or more corresponding operations.
Imaging tools can be fixedly or removably attached to various surfaces of test and measurement tools. An imaging tool comprising a sensor array capable of receiving electromagnetic radiation from a target scene can be configured to engage a surface of the test and measurement tool such that the imaging tool is supported by the test and measurement tool. When the imaging tool is engaged with the test and measurement tool, the sensor array can be movable relative to the imaging tool so that a target scene viewed by the sensor array of the imaging tool is adjustable without requiring movement of the test and measurement tool.

A method and apparatus for adjusting the focus of a camera. A rotatable focus member, when rotated, effects movement of an indicator element. The position of the indicator element is sensed by a sensing element and is passed to a controller within the camera. The controller prompts a motor to drive a focusing element of the camera in response to changes in the sensed position of the indicator element. The focus member effects movement of the indicator element by way of rolling resistance as opposed to sliding friction, allowing for more consistent and controlled manipulation.

VISIBLE AUDIOVISUAL ANNOTATION OF INFRARED IMAGES USING A SEPARATE WIRELESS MOBILE DEVICE
A smart phone user captures video and still images of a motor and makes a sound recording of his observations. The images and recordings are tagged with a date/time stamp, a serial, number, bar code, matrix code, RFID code, or geolocation and sent wirelessly to an infrared camera. The infrared camera has a collocation application that reads the tag and creates a folder which holds the infrared image and the auxiliary information from, the smartphone related to an asset. The collocation program also adds icons to the infrared image. By operating the user interface (not shown) of the infrared camera, the user may select an icon to view the images and listen to the sound recording.

In response, a second communication connection is established with the remote device, the measurement data to be shared is identified, and the identified measurement data is communicated to the remote device for review by the selected contact. Prior to establishing a communication connection with the remote device, permission to communicate the measurement data to the selected contact may be obtained from a gatekeeper.

A thermal imaging camera may be used to capture a visible-light (VL) image and an infrared (IR) image. In some examples, the camera includes a range imaging camera module that captures the VL and an infrared camera module that captures the IR image. In such examples, the VL image may include a plurality of different portions that each correspond to a different portion of the scene and distance-to-target data associated with each of the different portions of the scene. The camera may align each of the plurality of different portions of the VL image based on the distance-to-target data associated with corresponding portions of the scene so as to correct a parallax error between the VL image and the IR image. The camera may then concurrently display the VL image in alignment with the IR image.
A paint curing oven may include multiple infrared temperature sensors to indirectly measure the temperature of a painted object as the object is conveyed through the oven. In some examples, temperature measurements from the infrared temperature sensors are compared to temperature measurements from a temperature sensor physically carried by the painted object to develop a calibration relationship. In subsequent use in which the infrared temperature sensors measure the temperature of a painted object that does not carry a temperature sensor, the calibration relationship may be used to generate a simulated temperature curve. The simulated temperature curve may provide an estimate of the temperature of the painted object as would be determined by a temperature sensor physically carried by the painted object, were the painted object actually carrying the temperature sensor.

THERMAL IMAGER THAT ANALYZES TEMPERATURE MEASUREMENT CALCULATION ACCURACY
A method and computer program product for determining whether an object of interest can have its temperature measurement calculated by a thermal imaging camera. To do this, the measurement IFOV is converted into linear units. The measurement IFOV may be displayed on the display of the camera as a graphical indicator (100, 100', 100", 100"') or a value. An object of interest can be registered with the graphical indicator (100, 100', 100", 100"') or its dimension compared with the measurement IFOV and then it is determined whether the temperature measurement of the object can be acceptably calculated. Alternately, data obtained by a matrix of pixel elements may be analyzed to determine whether an accurate temperature can be calculated.
A system and method of conducting a full system test on a non-contact voltage detector while simultaneously shielding the voltage detector's antenna from stray electric fields is disclosed. When a user runs the self-test, an alternating current generator capacitively couples to the antenna through an antenna shielding to detect any breaks in the antenna. The coupled signal is amplified and filtered by the voltage detector's electronics, and triggers an indicator if the voltage detector is fully operative.
