Abstract: Example methods are provided to improve placement of an adaptor (210,220) to a mobile computing device (100) to measure a test strip (221) coupled to the adaptor (220) with a camera (104) and a screen (108) on a face of the mobile computing device (100). The method may include displaying a light area on a first portion of the screen (108). The first portion may be adjacent to the camera (104). The light area and the camera (104) may be aligned with a key area of the test strip (221) so that the camera (104) is configured to capture an image of the key area. The method may further include providing first guiding information for a user to place the adaptor (210,220) to the mobile computing device (100) according to a position of the light area on the screen (108).

Abstract: A device includes a receiving mechanism, a transmitting mechanism, and a signaling mechanism; the receiving mechanism is positioned in a remote control of an electrical equipment; the signaling mechanism is electrically connected to the receiving mechanism; the transmitting mechanism can be positioned in the electrical equipment; alternatively, the transmitting mechanism can be positioned outside the electrical equipment; the signaling mechanism will produce signals such as light and sound when the receiving mechanism receives signals transmitted from the transmitting mechanism, thus helping the user find the remote control.
