An optical semiconductor device such as a light emitting diode is formed on a transparent substrate having formed thereon a template layer, such as AlN, which is transparent to the wavelength of emission of the optical device. The first conversion circuit includes a digital to analog converter and a coupler. The voice-enabled application can utilize a speech recognition service to convert utterances to text. Based on the physical area, a status for a monitoring task of the camera can be updated andor a location of an area for the monitoring task within an image captured by the camera can be updated. The first path is selected from a set of paths; and the first and second cells are placed before the wire is routed to connect the first cell and the second cell.
