摘要:
Disclosed is a self-correlation receiver of a transceiver in which a transmitter shares an antenna with a receiver. The self-correlation receiver includes: a clamper which receives a received signal, limits the magnitude of the received signal within a predetermined range and outputs a clamping signal; and a mixer which receives the received signal and the clamping signal and outputs a signal having a difference frequency between the received signal and the clamping signal.

Disclosed is a jacket having a warm pocket capable of warming hands of a user without interrupting user's activity in the field. The jacket has a dual-layer structure of an inner skin and an outer skin so as to accommodate a warmer therein. A pocket is formed at a front part or a rear part of the jacket by sewing the inner skin with the outer skin in the form of a pocket. The pocket is formed at both sides thereof with openings so as to allow a user to put both hands into the pocket. An inner pocket formed at one side thereof with a hand warmer receiving section is coupled to an outer surface of the inner skin.

Provided are a semiconductor lead frame, a semiconductor package having the semiconductor lead frame, and a method of plating the semiconductor lead frame. The method includes preparing a substrate formed of a Fe—Ni alloy (alloy 42), and a plating layer that contains grains less than 1 micrometer in size and is plated on the substrate. The growth of whiskers when a Sn plated layer is formed on a substrate formed of a Fe—Ni alloy (alloy 42) can be suppressed by minimizing the grain size of the Sn plated layer.

A device for starting a vehicle in an emergency is disclosed. The device includes a fob key for transferring a starting signal for starting the vehicle via a wireless connection or a driver's authentication information via a Universal Serial Bus (USB) connection, and a vehicle starting unit for receiving the starting signal or the driver's authentication information, determining whether a driver in question is a valid user, and starting the vehicle. The vehicle starting unit includes an interface unit for receiving the driver's authentication information transferred via a USB connection, an audio unit for identifying the driver's authentication information transferred from the interface unit, and a Personal Identification Card (PIC) unit for receiving the driver's authentication information from the audio unit or the starting signal from the fob key, determining whether the driver in question is a valid user, and starting the vehicle.
