Abstract: An encryption key management method includes: receiving a data registration request from a supplier terminal, determining a data identifier associated with the content data, encrypting a master key with a public key of the supplier terminal, and providing the supplier terminal with the master key encrypted with the public key of the supplier terminal, the data identifier, and a key update count value; receiving a subscription application related to the data identifier from a first subscriber terminal, encrypting the master key with a public key of the first subscriber terminal, and providing the first subscriber terminal with the master key encrypted with the public key of the first subscriber terminal and the key update count value; receiving encrypted content data encrypted with the symmetric key and a hash for the content data from the supplier terminal; and transmitting the encrypted content data and the hash to the first subscriber terminal.

Abstract: A slim air vent for a vehicle includes an inner wing disposed in a duct to horizontally rotate during manipulation of a knob, an outer wing and a support wing disposed in the duct to vertically rotate during the manipulation of the knob, a knob pin horizontally penetrating through the knob to rotate together with the knob during the vertical rotation of the knob and to guide the knob during the horizontal movement of the knob, and a link mechanism provided to connect one end of the knob pin and the outer wing to vertically rotate the outer wing and the support wing during rotation of the knob pin according to the vertical rotation of the knob.

Abstract: A heating, ventilating, and air conditioning (HVAC) apparatus for a vehicle includes: a case, which is configured to communicate with the outside of the vehicle and which includes a discharge flow path connected to an interior of the vehicle; an outside air inlet, which is located in the case and into which air is introduced from the outside of the vehicle; an inside air inlet configured to communicate with the interior of the vehicle; a filter unit located adjacent to the discharge flow path; an inside/outside air switching door provided adjacent to the outside air inlet and the inside air inlet and configured to selectively open the outside air inlet and the inside air inlet; and an auxiliary switching door, which includes a depression located at a lower end of the filter unit and which is selectively opened so as to allow the depression and an outdoor outlet to be fluidly connected.

Abstract: A vehicle air conditioning system performing individual air conditioning in four zones for left and right spaces of front and rear seats includes a front seat heating, ventilation, and air conditioner (HVAC) separately supplying air having passed through left and right flow paths of a front seat flow path into the left and right spaces of the front seat to perform two-zone individual air conditioning for the front seat. A flow guide is provided in an upstream side space of an evaporator in an internal space of the air conditioning casing of the front seat HVAC to divide the upstream side space of the evaporator to have a left flow path and a right flow path. The flow guide and a side portion of the air conditioning casing opposite to the flow guide have a curved stepped portion in cross-section.

Abstract: An individual air conditioning control system for an electric vehicle, includes a heating, ventilation, and air conditioning (HVAC) body, an evaporator provided in the HVAC body, a PTC heater, an input unit for receiving set temperature of each of a driver's seat and a passenger's seat, left and right temperature sensing units of sensing an air temperature passing through a left side and a right side of the PTC heater, a control unit of outputting a control signal for controlling the PTC heater based on the set temperature input from the input unit and a measurement temperature measured from each of the left and right temperature sensing units, and a power supply unit of adjusting power supplied to the PTC heater according to the output PWM control signal of the control unit.

Abstract: A proximity sensor installed inside a vehicle can include: an outer frame formed of a first non-conductive substance and including a first metal layer; an inner frame formed of a second non-conductive substance, including a second metal layer, and disposed in an interior of the outer frame; a sensor electrode contacting the second metal layer; and a sensor Integrated Circuit (IC) connected to the sensor electrode and configured to detect an approach or a contact of a user's hand. The first metal layer can be connected to the ground (GND) so as to confine a sensing field of the sensor electrode to the interior of the outer frame.

Abstract: The present disclosure provides an air vent device including a garnish including an air vent hole, a second wing located inside the air vent hole in a vertical direction, a first wing located at an outer side of the air vent hole in a lateral direction and configured to be pivoted based on one end close to the outer side of the air vent hole, a deco part configured to surround the garnish and at least a portion of an outermost surface of the first wing, and a knob configured to control a direction of a wind discharged from the air vent hole, wherein the knob includes a knob of the first wing capable of adjusting a vertical wind direction by operating the first wing and a knob of the second wing configured to face a rear surface the knob of the first wing.

Abstract: A proximity sensor is provided. The proximity sensor has an exposed exterior surface formed of a metal material to improve the aesthetics thereof. The proximity sensor mounted within a vehicle includes a frame formed of a nonconductive material and a metal layer that covers an exterior surface of the frame. A sensor electrode contacts the metal layer and a sensor integrated circuit (IC) connected to the sensor electrode to sense an approach or a contact of a user on the metal layer.
