The present disclosure provides a parking method and an apparatus for an intelligent driving vehicle, a medium, a device, and a vehicle, including: determining a drivable region after gridding and a target parking space; expanding a current node in the drivable region from a parking starting point of the vehicle to obtain at least one candidate sub-node; determining a target grid where the candidate sub-node is located, and determining whether to retain the candidate sub-node in the target grid according to a node association relationship and/or a basic cost magnitude relationship between the candidate sub-node and a node already included in the target grid; determining a heuristic cost of the candidate sub-node to be calculated according to a retention relationship between the candidate sub-node to be calculated and the target grid, an online heuristic term and an offline heuristic term of at least one candidate sub-node; inserting the candidate sub-node into a priority queue; and popping a node having the lowest node total cost from the priority queue as a new current node, expanding the new current node, obtaining a target parking planning path when reaching the target parking space, and performing parking according to the path.

A frequency steered sonar (1) includes a transducer (10) configured to transmit underwater an ultrasonic transmission wave comprising a plurality of frequencies (fl-fm), each frequency of the plurality of frequencies being associated with a transmission direction, to receive a reflection wave from the transmission wave reflected on an underwater object, and to generate a reception signal from the reflection wave; and a filter (11a) configured to filter the reception signal in each transmission direction, a first time range (ΔT1) of the filtered reception signal being outputted from the filter by attenuating signal components having a frequency outside of a first bandwidth (Δf4), and a second time range (ΔT2) of the filtered reception signal being outputted from the filter by attenuating signal components having a frequency outside of a second bandwidth (Δf3), and to output the filtered reception signal for display or storage.

A fuel injector device includes a nozzle injector body and a valve needle. The nozzle injector body includes an inner annular surface that defines an injector cavity connected to a sac having an injector orifice. The sac includes a sac surface that defines a sac diameter and a sac volume wherein the sac volume is defined by the sac surface, the relief portion, and the needle tip. The valve needle reciprocates in the injector cavity to control fuel delivery through the injector orifice. The valve needle includes a needle tip portion having a needle seat transition edge positioned between a needle seat portion that extends at a needle seat angle and a relief portion that extends at a relief seat angle. The relief seat angle is greater than the needle seat angle to thereby increase a sac volume when the nozzle seat portion engages the nozzle seat.

A direct current (DC) power supply (202) is disclosed. Embodiments comprise a first load (204) that optionally includes a battery, an alternator (206), and a switch (208). The alternator (206) is connected in series to the first load (204). The switch (208) is configured to receive power control signals, and to couple the first load and alternator to a second load (214).

A device for monitoring an engine surface includes a fixture body defining a breather aperture. The fixture body includes a first face engageable with a surface of an engine cylinder bore. The first face defines a recess. The fixture body also includes a first end including a lip that engages with a cylinder block. The first end defines a first end aperture in fluid communication with the recess. The device also includes at least one biasing member coupled to the fixture body and configured to exert a force on the fixture body causing the first face of the fixture body to contact the surface of the cylinder bore.

The present invention relates to a satellite communication system comprising at least one satellite base station and at least one ground station, preferably a user equipment (UE), wherein the at least one satellite base station is equipped with a software-defined virtual node and a digital beam forming (DBF) front-end configured to connect directly to the at least one UE.

A method and system of manufacturing a mold, such as a dental mold. The mold is 3D printed and is then acid treated. 3D printing includes printing the mold in a bath of resin. Prior to acid treating the method further includes centrifuging the printed mold to remove excess resin. Acid treating includes exposing the printed mold to an acid solution, such as acetic acid. The method and system may include heating liquid on the mold. Following acid treating, the method includes curing the printed mold, such as curing via UV radiation exposure. The method and system may include thermoforming a sheet of thermoplastic over the mold.

Systems and methods are disclosed for recovering lithium inventory and extending the operational life of lithium manganese iron phosphate (LMFP) batteries exhibiting multiphase electrochemical behavior. In example implementations, a battery cell configured with LMFP cathode materials having phase-dependent lithium transport characteristics undergoes a controlled recovery operation initiated in response to aging indicators. The recovery operation includes regulating the battery cell to a defined elevated temperature range for at least one phase of a multiphase reaction and directing a charging process while the cell is within the temperature range to promote lithium-ion migration from less accessible regions to active electrochemical sites. In some implementations, the charging process includes a low-rate charge followed by a normal-rate discharge. The disclosed techniques may be implemented by a battery management system and are applicable to vehicle, industrial, and stationary energy storage systems to improve capacity retention, operational stability, and lifecycle performance of aged LMFP batteries.

A genset includes a generator, an enclosure, and a plurality of louvers. The enclosure defines a space that is at least partially enclosed, with the generator in the space. The louvers extend from the enclosure inward to the enclosed space. Each of the louvers include a short leg and a long leg, the long leg coupled with the short leg at an angle to the short leg.

Systems and methods for diagnosing a catalyst of an aftertreatment system is described herein. The system includes an exhaust aftertreatment system and a controller coupled to the exhaust aftertreatment system. The controller receives a dosing efficiency regarding a catalyst of the aftertreatment system and determines an actual aging condition of the catalyst based at least in part on the dosing efficiency. The controller further include receives temperature data indicative of an operating temperature of the catalyst, the temperature data having associated runtime durations and determines an expected aging condition of the catalyst based on the temperature data and the associated runtime durations. The controller transmits an early aging notification to a user device in response to the actual aging condition exceeding the expected aging condition.
