A robotic sprinkler comprises an autonomous device (100) and a working base (200) configured for the autonomous device (100) to dock. The autonomous device (100) is driven by a control unit (7) to perform a sprinkling mode and a recharge mode. In the sprinkling mode, the autonomous device (100) has a scanning module (4) to detect and plan a driving path for the autonomous device (100) to move along the driving path and perform a sprinkling operation. In the recharge mode, the autonomous device (100) receives a guide signal to move and dock on the working base (200) for replenishing water and/or recharging. The robotic sprinkler achieves automatic and precise irrigation of vegetation, saving water resources.

A gripper control structure has a jaw seat (1); two jaws (2), pivotally connected to the jaw seat (1) and each having a distal end pivotally connected to a connecting member (3); and an extension rod (6), having one end coupled to the jaw seat (1) and another end coupled to a control handle (5). A pulley mechanism (51) is provided inside the control handle (5). A linkage rod (4) is inserted through the extension rod (6) in the jaw seat (1) and connected to the connecting member (3). When a pushing block (52) of the control handle (5) is pressed by an external force to move linearly toward the inside of the control handle (5), the pulley mechanism (51) is pushed to drive the linking rod (4) to move so that the two jaws (2) are closed for gipping an object in an effortless manner.

A one-button controlled water spray gun has a switching valve unit (31) configured for controlling the flow of water and a button unit configured for controlling operation of the switching valve unit.

A first elastic member (44) is provided between the first button and the switching valve unit. A pusher (46) is provided on an outer periphery of the first button and is spaced apart from the second button. A second elastic member (47) is provided between the pusher and the switching valve unit. In the process of pressing and moving the second button, different pressing resistances are provided in sections according to the pressing distance, thereby providing a good operating feel.

An exerciser has a bottom base(10), a handle assembly(20), two swinging arms(30), a balance linkage assembly(40), a damper(50), a supporting rod(14), a seat post(60), and a seat(70). The handle assembly(20) is secured on an end of the bottom base(10). The two swinging arms(30) are pivotally connected with the bottom base(10). The balance linkage assembly(40) is arranged between the swinging arms(30) to allow the two swinging arms(30) to swing relative to the bottom base(10) in reverse directions respectively. The damper(50) is arranged between the two swinging arms(30) and the bottom base(10) to provide a resistant force to the swinging arms(30). The supporting rod(14) is mounted on the bottom base(10) at a position away from the handle assembly(20) and protruding inclinedly toward the handle assembly(20). The seat post(60) is adjustably inserted into the supporting rod(14). The seat(70) is adjustably mounted on a top of the seat post(60).

A universal rack assembly has multiple connecting heads (10, 10A, 10B, 10C, 10D, 10E, 10F, 10G, 10H, 101), a framework (80, 80F), multiple shelf supports (30), and multiple positioning units (40). The framework (80, 80F) has multiple support tubes connected with the multiple connecting heads (10, 10A, 10B, 10C, 10D, 10E, 10F, 10G, 10H, 101). Part of the multiple support tubes are multiple extruded tubes (20B, 20B1) each having a slide rail (22). Each shelf support (30) has a slider (31) and a support seat (32) connected to each other. The slider (31) is slidably mounted in the slide rail (22) along a height direction (H). Each positioning unit (40) is screwed with and mounted through the slider (31) to abut against the slide rail (22). Thereby, the multiple shelf supports (30) are height-adjustable and can be re-positioned by the multiple positioning units (40).

A multifunctional water spray gun comprises a gun body (100) and a spray head unit (200). The spray head unit (200) is rotatable for selecting one of nozzles (4) to communicate with an internal passage (102) of the gun body (100) for spraying water. The nozzles (4) include a circular nozzle (4a) and a fan-shaped nozzle (4b). The fan-shaped nozzle (4b) is driven by a dial portion (43) to rotate for a fan-shaped spray pattern in different diffusion directions. The circular nozzle (4a) is driven by an adjusting knob (45) to move forward and backward for adjusting a spray pattern. By optimizing the structure, the water spray gun reduces the internal space occupied and has multiple functions, making it easy to use.

A lithium iron phosphate precursor, the preparation of which includes: uniformly mixing a metal oxide, a dispersant, a carbon source, a lithium source, and a first lithium iron phosphate in an aqueous solution, followed by a first grinding to obtain a first precursor with a median particle diameter (D50) of 0.35 to 0.39 µm; then adding a second lithium iron phosphate to the first precursor, uniformly mixing, and performing a second grinding to obtain the lithium iron phosphate precursor with a median particle diameter (D50) of 0.35 to 0.39 µm. The overall process provided by the present invention is simple and does not require repeated replacement of materials, reaction environments, or equipment, reflecting the advantages of a continuous process. In addition, the lithium iron phosphate battery cathode material produced from this precursor exhibits high compaction density characteristics.

The present utility model relates to the field of linear telescopic mechanisms, in particular to a novel linear telescopic mechanism. The novel linear telescopic mechanism includes a base, a fixing frame, a moving device and a movement detection mechanism, wherein the fixing frame is fixedly installed at the middle part of an upper surface of the base, and the moving device is fixedly installed on the upper surface of the base and at one side of the fixing frame. The novel linear telescopic mechanism provided by the present utility model controls a storage battery to transmit power to a control motor by means of a controller, drives a moving rod to move through the operation of the moving device and the movement detection mechanism, blocks the signals of first infrared sensors or second infrared sensors by means of baffles.

A water spray gun includes a gun body (100) having a handle (1) and a barrel (2). The handle (1) has a water passage (11) therein. The water passage (11) extends to a front end of the barrel (2). A valve stem (6) is provided in the barrel (2) and extends out of the barrel (2). A control lever (4) is pivotally mounted on a rear side of the handle (1) and connected to the valve stem (6). A positioning buckle (3) is pivotally mounted on a top of the barrel (2) for securing the control lever (4). A spray head (51) is connected to the front end of the barrel (2). A front end (601) of the valve stem (6) has a guide hole (62) that is gradually enlarged toward the front end (601) of the valve stem (6). The valve stem (6) is driven by the control lever (4) to move, thereby changing an area of the guide hole (62), covered by the spray head (5), for regulating the flow rate of water.

The invention provides systems, methods, and computer-readable media for multi-factor authentication (MFA) using device and carrier validation. A user device generates an attested blob containing cryptographic keys and a Universal Integrated Circuit Card (UICC)-originated International Mobile Subscriber Identity (IMSI), which is transmitted to a cloud-based MFA service. The service validates the attested blob, coordinates with an Original Equipment Manufacturer (OEM) service, and executes an Extensible Authentication Protocol-Authentication and Key Agreement (EAP-AKA) process with the carrier network to establish mutual trust. Authentication data, including a validated phone number independent of the device's stored number, is securely stored in a cloud wallet. The invention enhances security by mitigating risks such as spoofing, replay attacks, and SIM swapping, providing a novel authentication framework compatible with modern networks.
