Abstract: A lawnmower is instructed to move from a reference point along the boundary wire and to follow the boundary wire along a boundary path back to the reference point, using data from at least one wire sensor of the lawnmower. One or more elements are determined along the boundary path using distance data from at least one distance sensor of the lawnmower and using angular velocity data from at least one angular velocity sensor of the lawnmower. The one or more elements are identified as one of at least three different types of elements. The mowing area is calculated from the identified types of the one or more elements and the distance data and angular velocity data received for the one or more elements.

Each of the at least one smart charging pile includes a charging gun, a power supply circuit, a camera module and a signal processing circuit. The power supply circuit is configured to provide electric power to the charging gun. The camera module is configured to capture at least one image associated with a vehicle. The signal processing circuit has at least one recognition model and is configured to use the at least one recognition model to perform an edge computation on the at least one image and control the power supply circuit according to a result of the edge computation. The cloud management center is configured to update the at least one recognition model of the signal processing circuit according to the result from the signal processing circuit.

Abstract: Systems and methods are described for implementing a coordinator within a coordinated environment, which environment includes set of coordinated devices managed by the coordinator. The coordinator can be provisioned with a set of tasks, each task corresponding to a segment of code that can be executed by the coordinator, such as to manage the coordinated devices. To assist in local storage and retrieval of protected data in the coordinated environment, the coordinator can include a protected data manager for storing protected data and managing access to the stored protected data. The protected data manager can communicate with a key manager to encrypt and decrypt the protected data. The set of tasks executing in the coordinated environment can access the protected data using unique security tokens.

Abstract: A juice extraction device for extracting juice from food includes a hollow juice extraction screw capable of being rotated along an axis and having a food inlet through which food enters the juice extraction device; a mesh filter for separating the juice from the food, the mesh filter encompassing the juice extraction screw; and a housing encompassing the mesh filter. The provision of a hollow juice extraction screw can minimize the length of the device while maintaining juicing efficiency. This feature also allows the device to be placed vertically, such that various components, including the juice exit, may be located at the bottom position for improved efficiency and convenience.

Abstract: The current invention provides an automatic gear-shift drive mechanism including a first gear system having a first gear ratio, and a second gear system having a second gear ratio, wherein the first gear ratio is higher than the second gear ratio, and is biased to spin the drying assembly with the first gear system when the automatic gear-shift drive mechanism is driven and the workload is below a threshold workload, and switch to spin the drying assembly with the first and the second gear systems when the automatic gear-shift drive mechanism is driven and the workload is at or above the threshold workload.

Abstract: Juice extraction device (100) is provided for extracting juice from food including a housing (102) having at least one food inlet (104); a process chamber unit (210) having at least one opening matching the at least one food inlet (104) to receive the food; a helical screw (220) capable of being rotated by a driver connected thereto along an axis; a mesh filter unit (230) for separating he juice from the food, said mesh filter unit (230) connected to the process chamber unit (210) to encompass the helical screw (220), wherein the mesh filter unit (230) has a cross-sectional shape perpendicular to the axis; at least one outlet (242) where the juice exits, the at least one outlet (242) is at a side of the mesh filter unit (230), wherein the distance between the helical screw (220) and the mesh filter unit (230) varies.

Abstract: The current invention discloses a food-drying device that includes a container, a drying assembly having a plurality of bores, and a drive mechanism. The drying assembly is disposed in the container and is capable of being rotated relative to the container. The drive mechanism rotates the drying assembly relative to the container. The drive mechanism includes a reciprocating handle movable between a first position and a second position along a linear direction, and a conversion mechanism for converting reciprocating movement of the reciprocating handle to rotary motion of the drying assembly from force supplied by a user to actuate the reciprocating handle moving from the first position to the second position, and from force supplied by the user to actuate the reciprocating handle moving from the second position to the first position.
