20120303331 | ADAPTER BETWEEN SCALE AND VITAL SIGNS MONITOR - A method, an adapter and a system including a medical device and an adapter. The adapter receives patient scale data (e.g., height and weight data) from a scale. The patient scale data is in a first format data generally not interpretable by a vital sign monitoring device. The adapter translates the patient scale data into a second format compatible with the vital sign monitoring device. The adapter then outputs the translated data to the vital sign monitoring device. The scale and adapter may be coupled via a universal serial bus (USB) connection. The adapter and vital sign monitoring device may be coupled via one of a USB connection and an RS-232 connection. The patient data may be stored in an electronic health records (EHR) database by the vital sign monitoring device. | 11-29-2012 |
20130211789 | METHOD AND DEVICE FOR SIGNAL PERIOD STRETCH AND ULTRA-FAST SERIAL-TO-PARALLEL/PARALLEL-TO-SERIAL CONVERSION - Disclosed are a method and a device for signal period stretch and ultra-fast serial-to-parallel/parallel-to-serial conversion, which relate to the technical field of analysis and measurement control. The method is to change a propagation velocity of a target signal or displacement-reflecting the target signal, so as to extend or compress the period of the signal. Displacement-reflection is to generate a Doppler shift through interaction of the displacement of a reflecting plate with the target signal, so as to achieve period stretch; for a signal transmitted through a medium, the propagation velocity of the target signal is changed by changing the property of the medium, so as to achieve period stretch; for a signal ascribed to an electron flow, the movement velocity of the electron beam is changed through a varying acceleration field, so as to achieve period stretch. A target signal condensing/diffusing and collimating lens, a synchronous signal controller and a plurality of period stretch devices are utilized to achieve ultra-fast serial-to-parallel/parallel-to-serial signal conversion. Thereby, a device that originally cannot work at the frequency spectrum of the target signal is enabled to observe, transmit and parse content of the original target signal. | 08-15-2013 |
20130246007 | SENSOR SIGNAL PROCESSOR - A microcomputer which constitutes an ECU transmits a start/stop signal and a crank angle signal to an analog input circuit. The analog input circuit is activated when the start/stop signal is received. The A/D converter converts a sensor signal into a digital signal. The digital processor detects a peak value of the digital signal. A counter restarts a counting operation when the crank angle signal is received. A data register sends a detected data of the peak value as a specified information adding by a count value and an information of the crank angle signal to the microcomputer. The microcomputer acquires the crank angle of the specified information by computing the crank angle from the detected data. | 09-19-2013 |
