Abstract:
A defibrillator having a pair of electrodes for delivering an impedance-compensated defibrillation shock and a method thereof is provided. The defibrillator can be deployed rapidly and effectively with no or minimal clothing and hair removal. To achieve this, one electrode is coupled to a neck region of the patient, whereas the other electrode is coupled to the patient's body. Both attachment areas are easily accessible to the rescuer, thus allowing a minimally trained user to easily deploy the defibrillator to treat the patient. A wide range of energy levels that are safe for the patient can be generated selectively based on the patient impedance. The presence of voids in the electrodes decrease the effective shock impedance of the electrodes, thus allowing the defibrillator to operate at a lower level of energy when delivering the electrical pulse to the victim's heart.
Abstract:
The application relates to an information transfer system, comprising a receiver (3) and a transmitter (1) for transferring an information signal to the receiver (3) via a transfer medium (2). The information signal comprises main data and sub data. The sub data comprises coded text lines having a plurality of character codes. The receiver is provided with a character display unit (10) for displaying characters corresponding with the character codes in the coded text lines. The number of character display positions is less than the number of character codes in the coded text line. The receiver is provided with display control means (9) for controlling the display of characters corresponding to the character codes included in the coded text line in dependence on serial control codes included in the coded text line. The system enables that significant parts of the text information available in the sub data can be shown on both a full multi-line display units for displaying full text lines and a 1-line display with a relative small number of digits. The invention is very suitable for systems with small sized receivers, such as e.g. portable players and car radios, and receivers wit a display on its remote controller, because there is not much space available for a display unit.
