摘要:
Embodiments of the present invention may provide a PET-MRI hybrid system capable of arranging a PET apparatus and an MRI apparatus in a line. An MRI room containing the MRI apparatus and a PET room containing the PET apparatus are provided at either side of a central waiting room as opposed to each other about the waiting room. A rail portion linearly extends from the PET room to the waiting room on their bottoms. Another rail portion linearly extends on the bottom of the MRI room. A transfer unit, which supports a subject lying thereon, travels along the rail portions of the waiting room, the MRI room and the PET room. A bridge unit is provided between the rail portion of the waiting room and the rail portion of the MRI room. The bridge unit provides a space for opening and closing a shield door of the MRI room and allows the transfer unit to be reciprocated between the waiting room and the MRI room by selectively connecting the rail portion of the waiting room and the rail portion of the MRI room.

A drying machine is disclosed. The drying machine includes a selectively rotatable drum receiving an object to be dried, a steam supply member having one side connected to a steam generator and the other side connected to the drum, and a swirler installed in the steam supply member at a predetermined position for swirling steam flowing through the steam supply member. A method for controlling the drying machine includes heating a drum, supplying steam generated in a steam generator into the drum, and supplying hot air into the drum. The drying machine having the above described configuration can efficiently eliminate creases of clothes.

The present invention relates to a radar detector having the function of a hands-free device, so that it is possible to talk over a mobile phone in a hands-free manner by connecting the mobile phone to the radar detector. The radar detector comprises a horn antenna 100; a signal-processing unit 200 for detecting a signal received by the horn antenna 100; a laser module 300 for receiving a laser signal; a central processing unit 400 for controlling the signal-processing unit 200 by generating a pulse to measure and calculate the period and width of the signal detected by the signal-processing unit 200, to analyze and output the bandwidth and information of the signal, and to find the type and information of the signal over time; a pulse delay unit 500 for delaying or sustaining the pulse received from the central processing unit 400; a sweep voltage generator unit 600 for driving the signal-processing unit 200 by generating a voltage from the pulse delay unit 500; a warning unit 700 for audibly or visually warning the detected signal; an audio amplifier controller 800 connected to the central processing unit 400 and the warning unit 700 to amplify an audio signal; and a mobile phone connecting unit 900 installed to connect the audio amplifier controller 800 with a mobile phone 10 and including a microphone 910, a switch 920 for reception of a signal from the mobile phone, and a connection portion 930 for connection to the mobile phone. According to the present invention, a user can talk over a mobile phone using an additional function of the radar detector, without a need for mounting an additional hands-free device for conversation by the phone in a vehicle with the radar detector installed therein, thereby improving user's convenience.

A decoder, a method of decoding and systems implementing the same are disclosed. In one example, the method includes calculating syndrome values from input codewords, generating an error location polynomial about the codewords using the syndrome values, determining an error count in the codewords using the error location polynomial, and adjusting power consumption of a circuit in response to the determined error count in the codewords. In one example, a frequency of a clock signal to be provided to a search circuit may be determined based on the error count, and the clock signal may be provided having the determined frequency to a search circuit, such as a Chien search circuit.
