A smart key system of a vehicle that notifies a user that a fob battery needs to be replaced, including a fob configured to transmit information that the battery needs to be replaced to an in-vehicle communication module configured to transmit the information to an identification authentication unit (IAU); and the IAU configured to transmit the information to an integrated body unit (IBU) configured to notify a user of the information. A smart key system includes: a fob configured to transmit failure information to a BLE module when UWB communication fails due to battery voltage drop; the BLE module configured to receive the failure information, and measure a distance for positioning the fob using a BLE signal; and an IBU configured to transmit an operation signal to a controller configured to control at least one function among vehicle door opening and closing, vehicle start, remote parking, and vehicle door locking.

Smart key system capable of operating even when UWB communication is impossible due to battery voltage drop of fob and operation method thereof

A low power operating method for a smart key remote controller of a vehicle , wherein the method includes connecting the smart key remote controller to a smart key control system in a vehicle based on a first frequency signal, after the connection, acquiring a vibration detection value through a vibration detection sensor, checking a strength of the first frequency signal (a received signal strength indicator (RSSI)) received after the connection, determining whether the vibration detection value is greater than or equal to a preset vibration value and the strength of the first frequency signal is greater than or equal to a preset signal strength value, and when a determination result is satisfied, activating a module corresponding to a second frequency signal.

High efficiency seawater evaporation apparatus comprises showering unit installed at the saltpan; and evaporation rope module wherein multiple evaporation ropes are collected in group by the holder and the respective evaporation modules are extended along the upper and lower direction in the state each other separated in a predetermined interval and wherein, when the seawater is supplied to the respective evaporation ropes by the showering unit, the seawater may flow down along the surface of the respective evaporation ropes and the evaporation of the seawater may be accelerated.

Sea water evaporator, and evaporation rope module for salt production

Provided a salt production automation system utilizing three-dimensionally structured evaporation fields. The salt production automation system utilizing three-dimensionally structured evaporation fields includes: evaporation fields which have collection pools (SWT) and are installed in at least two separate places; a plurality of evaporation members which are three-dimensionally arranged in the evaporation fields to make seawater flow downwards; and a seawater supply unit which supplies seawater to the evaporation members so that seawater can flow downwards from the evaporation members, wherein among the evaporation fields, the number of evaporation members gradually decreases from the first stage evaporation field to the final stage evaporation field.

Provided are a smartkey system and an operating method thereof. The smartkey system reflects an intensity of RF noise, which is detected in a zone having strong RF noise, in a fob indoor/outdoor position determination reference, and thus can prevent a determination error in which the presence of a fob is determined despite there being no fob registered in a vehicle, and prevent an operational reaction to a user's request from becoming slow.

Smartkey system and operating method thereof

This invention includes the derivation of the exact mathematical expressions for the curvature, either cardiocle or expanded cardioid, of the casing of the springless eccentric rotor vane pump, thereby facilitating the precision manufacture of the curved surfaces of the casing using CNC techniques. As a result, the capacity and accuracy of the eccentric rotor vane pump is greatly improved. As the section manufacture and assembly of the casing becomes possible, the mass production of large-sized pumps of 1-meter or larger diameter is now attainable, hitherto regarded as almost impossible, and therefore production cost is also reduced. The unique design which positions the axis of eccentricity in the lower central part of the axis of rotor rotation results in increase in the rotation speed of the rotor, and leads to reduction of friction between the vane ends and the curved surface of the casing as the weight of the vane does not affect the movement of the rotor.
