In an aspect, a device-and-clip system is provided for an electronic device. The system includes an external device that cooperates with at least one electronic device feature on the rear face to perform a selected function. The system includes a clip including a first clip arm having an arm marker thereon and which is engageable with the front face of the electronic device and a second clip arm that is engageable with the rear face of the electronic device. The system further includes an application that is executable to instruct the electronic device to display a screen marker on the display screen in a selected position and in a selected orientation such that positioning and orienting of the first clip arm on the display screen of the smart phone with the arm marker aligned with the position and orientation of the screen marker positions the external device in alignment with the at least one electronic device feature.

An image projection device is disclosed having a body defining an aperture that includes a slide frame receiving slot that is transverse to the aperture and a magnifying lens positioned in alignment with the aperture at the front of the body. The image projection device can be attached to a mobile device and uses the camera flash of the mobile device to provide the light source to illuminate a slide transparency. The mobile device can identify a particular slide transparency through information encoded on the slide frame in order to coordinate audio or video output with the projected slide.

A positioning system has at least one positioning carriage which is variably mobile and positionable relative to a carriage support of the positioning system, whilst carrying out a positioning movement on a positioning plane defined by an xy cartesian co-ordinate system, the carriage support having at least one stator arrangement with an x-stator section for providing a magnetic x-travelling field, which can be moved in the direction of the x-axis of the xy co-ordinate system, and a y-stator section for providing a magnetic y-travelling field, which can be moved in the direction of the y-axis of the xy co-ordinate system. The positioning carriage is provided with a magnet arrangement which, during the positioning movement, magnetically interacts simultaneously with the x-travelling field and the y-travelling field.
