    摘要: A method is disclosed for performing data communication between a pair of circuits. The data communication is established by serially transmitting information which includes pulse signals. In executing the method, a reference time is determined as an instant of a first level change in a first direction of a pulse signal output from one of the circuits to the other. A judgement is made as to whether a first bit of data is a "1" or a "0" in accordance with a time period extending from the reference time to an instant of a subsequent level change in the first direction following the reference time. The instant of the subsequent level change in the first direction is determined as a reference time relative to the next bit of data in the pulse signal. The data of a predetermined number of bits is continuously transmitted by repeatedly establishing reference times and judging the value of a bit based on the time period which extends from the reference time to a subsequent level change.

    摘要: The present invention is directed to methods of treating movement disorders by administering an effective amount of one or more adenosine A2A receptor antagonists to a patient in need thereof. The present invention also provides methods of decreasing the adverse effects of L-DOPA in patients receiving L-DOPA therapy in the treatment of Parkinson's disease. The present invention further provides methods and compositions for treating Parkinson's disease patients with sub-clinically effective doses of L-DOPA by combining L-DOPA treatment with an effective amount of one or more adenosine A2A receptor antagonists (i.e., L-DOPA sparing effect). The present invention further provides methods of effective treatment of Parkinson's disease by co-administering at least one adenosine A2A receptor antagonist, L-DOPA and a dopamine agonist and/or a COMT inhibitor and/or a MAO inhibitor. The present invention further provides methods of prolonging effective treatment of Parkinson's disease by administering an adenosine A2A receptor antagonist singly or together with a dopamine agonist, and/or a COMT inhibitor, and/or a MAO inhibitor without prior or subsequent administration of L-DOPA, delaying or removing on-set of L-DOPA motor complication.

    摘要: A digital camera includes an image pickup device which converts incident light of an object image into an electrical signal during an exposure operation; a processor which captures the electrical signal, and thereafter generates a digital image from the electrical signal; a battery checking device which performs a battery check process for determining whether a battery voltage of the digital camera is lower than a predetermined voltage level; a controller which forcibly terminates the exposure operation when the battery checking device determines that the battery voltage drops below the predetermined voltage level during the exposure operation, and subsequently makes the processor start capturing the electrical signal in order to generate a backup digital image; and a warning device which warns a user that the exposure operation is forcibly terminated due to a shortage of the battery voltage and that the backup digital image is underexposed, in the case where the exposure is forcibly terminated.
