Abstract: In an indoor environment on fire, automatic deployment of sensors disposed on, beneath or over the floor to look upward the ceiling to observe a body of smoke and flame risen near the ceiling allows important information regarding states and dynamics of the body of smoke and flame to be gathered at an early stage of fire (e.g. before arrival of firefighters). By distributing the sensors over the indoor environment, the states and dynamics of the body of smoke and flame are monitored holistically (i.e. as a whole) even at the early stage of fire. Such information is useful to predict development of the fire. In one implementation, a sensor is held in an infrastructure sensor holder mounted on the ceiling during normal time. Upon detecting occurrence of fire, the sensor drops from the holder to land on the floor and orients a sensing direction vertically upward to perform monitoring.

Abstract: Provided is a sink with an embedded shower head. The sink includes a sink main body and a water outlet device, wherein the water outlet device includes a shower head assembly and a switch assembly which are matched with each other. The shower head assembly includes a shower head, a cover plate and a connecting piece. A plurality of water outlet holes are uniformly formed in a surface of the shower head. The cover plate includes a water outlet, the water outlet and the switch assembly are connected through the connecting piece, and the cover plate is closed and installed on the back of the shower head.

Abstract: Provided is a display panel. The display panel includes a substrate, an anode layer, a planarization layer and an organic functional layer. The anode layer is disposed on a side of the substrate, the planarization layer is disposed on a side of the anode layer away from the substrate and configured to cover the anode layer, and the organic functional layer is disposed on a side of the planarization layer away from the anode layer.

Abstract: The present disclosure discloses a sink with an assembled stand. The sink includes a sink main body and an assembled stand; the assembled stand includes a left stand, a right stand, a connector and a surrounding panel; the connector connects the left stand with the right stand; the surrounding panel is mounted between the left stand and the right stand; the sink main body is movably mounted on the assembled stand; and the surrounding panel covers side surfaces of the sink main body. The present disclosure has the beneficial effects: The sink can flexibly meet requirements of a user for usage scenarios by a structural design of a sink supporting main body. Furthermore, a DIY product is provided to reduce the transportation cost, and the user can assemble the sink easily on the own.
