Abstract: A low profile light comprises mating front and back housings (12, 14), between them defining the thickness of the light. An attachment is provided on the back housing, whereby the light is attachable to a base on which the light is to be mounted. A circuit board (16) mounts circuit elements (36) and interconnecting conductive tracks to which LED devices (28) are connected. The board is enclosed and sandwiched between said front and back housings. The front housing is transparent or translucent to transmit light emitted from the LED devices. The circuit elements and LED devices are arranged to be powered by AC mains electricity. The thickness of the light is no greater than 10% more than the sum of the thicknesses of said front and back housings and the maximum 15 dimension of a minimum power-rating two-core mains electricity power cable (18). That is, it is less than 10 mm thick.

Abstract: A method of rocking a wheeled infant carrier (30) comprises using a rocking device (10) having a pair of discrete units (12,14). Each unit has a ground-engaging base (18a,b) and a platform (16a,b) supported thereon through bearings for movement relative to the base in a first direction. A drive one (12) of the units has a motor in a housing (20) arranged to drive the platform (16a) of the drive unit relative to its base back and forth in said first direction. A first wheel (34) of the carrier (30) is placed on the drive unit and a second wheel (32) on the second, slave unit (14), with the axes of rotation of the wheels being arranged parallel said first direction. The motor is operated to rock that end of the carrier that is supported by those wheels from side to side.

Abstract: A method of rocking a wheeled infant carrier (30) comprises using a rocking device (10) having a pair of discrete units (12,14). Each unit has aground-engaging base (18a,b) and a platform (16a,b) supported thereon through bearings for movement relative to the base in a first direction. A drive one (12) of the units has a motor in a housing (20) arranged to drive the platform (16a) of the drive unit relative to its base back and forth in said first direction.
