Abstract: A retrofitting system designed to convert an adult-size bed into an infant/toddler bed is disclosed. The retrofitting system comprises first a template is being placed on a twin, full, queen, king-or larger size bed with an underside of the template fitted to an underside of a mattress. The system further comprises a number of interconnecting geometrical shape structures connected to the template on the bed. The template and geometrical shape structures can be disassembled and assembled (with or without accessories) into furniture (storage cabinet, diaper change table, chair, table, and others), toys (easel, activity center, car, slide, picnic table, wagon, snake, puzzle board and others) and other useful items, such as a security gate or storage cabinet for providing storage spaces for baby clothing, diapers, lotion, towels, baby powder, baby wipe etc.

Abstract: An air-conditioner with high-efficiency differential cold-valley pipes, which include J pipes and a low-pressure circulating pump, has a first arc heat-exchanger which is formed by multiple-layer ladder-shaped corrugated plates and multiple-layer arc J pipe stacked alternatively, and a second arc heat-exchanger which is formed by multiple-layer arc J pipe and multiple-layer wave-shaped film-type evaporation face stacked alternatively. A low pressure pump is connected between the first arc heat-exchanger and the second arc heat-exchanger through pipelines. The air-conditioner solves the problems that the conventional air-conditioner consumes high energy, quality of the air in the room is low and the use of CFCs is confined.

Abstract: A message output controller (103) which receives continuous pre-recorded advertising messages from a master message playing device and console (101). The system incorporating several controllers (103) and a single console (101) is intended to be installed in a fuel service station, to provide advertising at fuel dispenser pumps. The console (101) plays messages continuously with a tone or the like between each message. The console (101) may include other features such as a public address (PA) system (111 and 113). The controllers (103) each receive the messages, but the messages are not played until a person is proximal, indicated by sensing (141) the nozzle being lifted in the fuel dispenser pump, and the tone or the like indicating a transition between messages being decoded (137). The result is that only complete messages are played at the controller (103).

Abstract: A retrofitting system designed to convert an adult-size bed into an infant/toddler bed is disclosed. The retrofitting system comprises first a template is being placed on a twin, full, queen, king-or larger size bed with an underside of the template fitted to an underside of a mattress. The system further comprises a number of interconnecting geometrical shape structures connected to the template on the bed. A plate/channel system is used to connect the geometrical shape structures to the template. The template and geometrical shape structures can be disassembled and assembled for storage, cabinet, diaper change table, chair, table etc., as the child grows up. The system can further be converted into children's toys, such as a car, slide, activity center, snake etc. with accessories.
