The first receiving lens is used to receive an echo light and output, so that the echo light is directed to the first receiving plate, and the echo light is formed by reflection of the detection laser from the target object; the camera module is mounted on the housing, and the camera module is used to acquire an image; the first predetermined direction is parallel to the optical axis of the transmitting lens. The detection device in this application makes the LiDAR function module and the vision function module integrated together, and the occupied space of the movable equipment can be relatively small, which is conducive to meeting the demand for miniaturisation of the movable equipment.

A wall-mounted structure and a household appliance are provided. The household appliance includes a household appliance body. The wall-mounted structure includes an installation part and two hanging parts. The installation part is configured to install the household appliance body. A minimum thickness of the installation part in a front-rear direction is a first thickness. One of the two hanging parts is connected to a left end of the installation part, and another one of the two hanging parts is connected to a right end of the installation part. Each hanging part is provided with at least one hanging hole. A minimum thickness of each hanging part in the front-rear direction is a second thickness. The first thickness is less than the second thickness. The technical solution of the present application can reduce the space occupation of a wall-mounted household appliance, and improve the appearance and utilization rate of the space.

Provided are a hanging bracket and a household appliance. The hanging bracket includes a mounting member and two hanging supports. The mounting member is configured to be connected to a household appliance body. The two hanging supports are connected to a left end and a right end of the mounting member, respectively. Each of the two hanging supports has at least one hanging hole and a hanging groove located below the at least one hanging hole. The hanging groove has a dimension in a left-right direction greater than a dimension of the at least one hanging hole in the left-right direction. When replacing the household appliance, a user can selectively choose the hanging hole or the hanging groove for an assembly with a hook. When the hanging groove is chosen for the assembly, since the hanging groove has the size in the left-right direction greater than the size of the hanging hole in the left-right direction, the hanging groove can provide a greater adjustment space to adapt to hooks arranged with different spacings, which reduces damage to a wall, and improves an assembly efficiency.

A water temperature in a water tank of a water heater is acquired during operation of the water heater, and a water usage status of a user is determined according to a change of the water temperature in the water tank, such that the influence of the amount of water from the water heater used by the user in each time period of a day on the water temperature in the water tank can be learned.

The invention pertains to a computer-implemented method for updating the state of multiple objects for multiple clients. This method involves maintaining a global state on a server, which is stored in a heap memory arranged in pages. This global state comprises multiple objects, each with an object header that includes an object identification, a version, and a zone. The method identifies zones of interest for each client and creates a snapshot for each client, which includes updates for all objects whose zone matches one of the client's zones of interest. This snapshot is then transmitted to the client. The method is characterized by an allocation counter that increases each time an object is allocated to the heap memory, and the object identification of the allocated object is set to the allocation counter. When an object changes its zone, the object version number increases. The creation of the snapshot involves checking if the zone of the object is a zone of interest for a client and, if positive, checking if the zone and version of the object match the zone and version in the client state. Depending on the outcome, a delta is created between the object state on the server and the object state of the client or a zero state. This calculated delta and an offset of the position in the heap where the delta is to be applied are included in the snapshot.
