Abstract: According to the first aspect of the disclosure, a method of forming a light emitting device array precursor is provided. The method comprises forming a first light emitting layer on a first substrate, forming an array of first light emitting devices from the first light emitting layer, each first light emitting device configured to emit light having a first wavelength. A first bonding layer is formed on the first light emitting layer. A second light emitting layer is formed on a second substrate, the second light emitting layer configured to emit light having a second wavelength different to the first wavelength. A second bonding layer is formed on the second light emitting layer. The second bonding layer is bonded to a handling substrate, followed by removing the second substrate from the second light emitting layer. A third bonding layer is formed on the second light emitting layer on an opposite side of the second light emitting layer to the handling layer.

Abstract: This device consists primarily of a hollow and portable base in which is secured an electric motor and attached, speed reducer, which by articulating rod means will oscillate from front to rear, a carriage in which the baby is placed. The carriage of the device depends from pivotable link rods secured to tubular rails fastened fixedly within the base portion of the device.
