Abstract: Systems and methods are provided for a battery management system (BMS) having a protection circuit. In one example, a vehicle battery system may include the BMS, the BMS including a cutoff circuit electrically coupled to the protection circuit, and a battery pack, a positive supply line of the battery pack being electrically coupled to the cutoff circuit, wherein the protection circuit may include each of an input electrically coupled to a control input of the cutoff circuit, an output electrically coupled to an output of the cutoff circuit, and a control input of the protection circuit electrically coupled to the output of the cutoff circuit. In some examples, the protection circuit may further include a low-current leakage transistor configured to maintain the cutoff circuit in an OFF state upon detection of a reverse bias voltage. In this way, the protection circuit may mitigate unexpected switching ON of the cutoff circuit.

Abstract: A base station antenna comprises a reflector assembly and a first radiating element having a first feed stalk and a first radiator. A base of the first feed stalk is adjacent the reflector assembly and the first radiator is adjacent a distal end of the first feed stalk. A center of the first radiator is offset from the base of the first feed stalk in a longitudinal direction that is parallel to a longitudinal axis of the base station antenna.

Abstract: The present disclosure is directed to a mounting bracket adapted for adjusting the downtilt of an antenna. The mounting bracket includes a first member and a second member. The first member is coupled to the second member at one end via a first pair of securing features and is coupled to an antenna mounting bracket at an opposing end via a second pair of securing features. The first member is configured to rotate about the first and second pairs of securing features relative to the second member and antenna mounting bracket, respectively.

Abstract: An easy-to-switch water outflow device includes a body, a water outflow assembly and a water channel switching device. The water outflow assembly is at least capable of spraying out two different functional water sprays; for each of the functional water sprays, the water outflow assembly is provided with at least one water inlet communicating with a water channel of the functional water spray, and the water outflow assembly is provided with a pivoting passage at a position corresponding to the water inflow terminal. The water channel switching device includes a water distribution valve spool, a connecting rod and a switching handle. By rotating the switching handle, the water outlet of the water distribution valve spool can be selectively docked and communicated with the water inlet, thereby realizing the switching of water channels of different functional water sprays of the water outflow device.

Abstract: An manufacturing device for amino acid coordination complexes, containing a reaction mechanism including a paddle drying reaction kettle, a motor, a rotation shaft, and paddles; a wet-type dust collector; a vacuum pump, and an ozone generator; one end of the rotation shaft is connected to the motor; another end of the rotation shaft extends into the paddle drying reaction kettle; a plurality of paddles are disposed on an outer wall of the rotation shaft and are rotatable along with the rotation shaft; the paddle drying reaction kettle is connected to one end of a vacuum pump through a gas discharging pipe; another end of the vacuum pump is connected with the ozone generator; a middle part of the gas discharging pipe is connected with the wet-type dust collector; the wet-type dust collector has a first wet filter tank and a second filter tank.

Abstract: The bread maker includes a housing for mounting of a container, an infrared transceiving device and a determining device. The container stores bread ingredients therein and has an outer surface provided with a color symbol. The infrared transceiving device includes an infrared emitting unit and a processing unit. The infrared emitting unit is operable to emit infrared ray toward the color symbol when the container is mounted to the housing. The processing unit is configured for receiving a reflection ray reflected from the color symbol and is operable to output an identification signal according to intensity of the reflection ray. The determining device is communicatively connected to the processing unit for receiving the identification signal and is operable to determine, with reference to the identification signal, a bread-making indicator that is associated with a bread making program, which the bread maker executes automatically to make bread using the bread ingredients stored in the container.
