Abstract: 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.

Abstract: A fiber end-surface inspection device and method illuminates the fiber end-surface from at least 2 different illumination angles, taking observations at the different angles, for detection of fiber end-surface imperfections, scratches or the like.

Abstract: A digital checklist system includes an electronic calibration and measurement device and a computer-readable medium having computer-executable instructions stored thereon that, if executed by one or more processors of a computing device, cause the computing device to perform actions for managing a digital checklist The actions include creating a digital checklist having at least one unique prompt, selecting the digital checklist for uploading onto the electronic calibration and measurement device, and downloading data input into the electronic calibration and measurement device in response to the at least one unique prompt. The system further includes a network location for facilitating communication between the electronic calibration and measurement device and the computing device.

Abstract: A digital multimeter includes a body having a function selector and a first coupler and includes a head having a display and a second coupler. The function selector selects a parameter to be measured, and the display displays a measurement corresponding to the parameter to be measured. The first and second couplers are engaged in a first arrangement joining the body and the head, and the first and second couplers are disengaged in a second arrangement separating the body and the head.

Abstract: A testing device which may be used to conduct ground resistance and soil resistivity measurements. The testing device comprises both a main unit and a remote unit adapted to communicate with one another via a communication link. After setting the testing device up according to the desired measurement technique, the procedure may be carried out, and the resulting measurement values are subsequently displayed on the remote unit. This allows a single operator to perform measurements while standing directly adjacent to an electrode, which is, for example, placed at a large distance from the main unit and/or other electrodes. This relieves the operator from constantly having to walk back and forth placing electrodes in different positions, and also obviates the need to return to the main unit of the testing device to consult a display and/or change parameters or settings.

Abstract: A method of automatically binding first and second devices for RF communication is disclosed. One step of the method involves establishing a secure, non-RF communication mode between the first and second devices. According to another step, first and second communication addresses respectively identifying the first and second devices are exchanged in the secure, non-RF communication mode such that the first and second devices will recognize each other as communication partners. The secure, non-RF communication mode is then terminated and an RF communication mode is established between the first and second devices as a first bound pair.

Abstract: A system and method are disclosed for controlling a drywell including a receiver having upper and lower ends with the lower end being more insulated than the upper end having a temperature sensor in thermal contact therewith. Upper and lower heating elements are in thermal contact with the upper and lower ends, respectively. A controller includes an integrated circuit having a temperature sensor. A reading from the integrated circuit is used to control power to the upper heating element and reduce a temperature gradient between the upper and lower ends of the receiver.

Abstract: An array of induction coil sensors is used to monitor, from multiple locations, the strength of a magnetic field generated by a wire to be traced. The magnetic field strength data is used to determine the location and orientation of the wire. In one embodiment, the sensor array is incorporated into a test instrument. The screen of the test instrument provides a graphical user interface that shows the orientation of the wire and indicates the location of the wire relative to the instrument.
