  • Publication number: 20080299047
    Abstract: The present invention relates to a process for preparing water-soluble and dispersed iron oxide (Fe3O4) nanoparticles and application thereof, characterized in which two-stage additions of protective agent and chemical co-precipitation are employed in the process. In the first stage, Fe3O4 nanoparticles are obtained using absorbent-reactant coexistence technology. In the second stage, proper amount of adherent is added to cover the nanoparticle surface entirely. The resulting water-soluble and dispersed Fe3O4 nanoparticles can easily bind with thiols or biomolecules, such as nucleic acid and peptide. The Fe3O4 nanoparticles of the present invention may be used as magnetic resonance imaging contrast agent and used in magnetic guiding related biomolecular technologies for clinical testing, diagnosis and treatment.

  • Publication number: 20060187209
    Abstract: A computer input apparatus is disclosed which has improved safety control. Computer input devices with coherent light sources are popular. However, coherent light sources may cause serious and unrecoverable injuries to human eyes. Accordingly, there are several safety specifications defined by manufacturers and governments. Therefore, an improved device is disclosed that includes a calibration circuit and a fault detection circuit to control the operation current of a coherent light source to be within the safety specifications range, and to monitor for fault conditions. Furthermore, a computer input apparatus with coherent light source can be operated without the traditional optical lens.

  • Publication number: 20040119531
    Abstract: A DC offset canceling circuit. The DC offset canceling circuit applied in a variable gain amplifier includes chopper circuits, a transconductance amplifier, and at least one internal capacitor. The transconductance amplifier and at least one capacitor function as a filter for canceling DC offset of the variable gain amplifier. A first chopper circuit is inserted between the output of the variable gain amplifier and the input of the transconductance amplifier. A second chopper circuit is inserted between the output of the transconductance amplifier and the capacitor. The DC offset and low frequency noise of the transconductance amplifier, the undesired signal, is translated up to a chopping frequency by chopper circuits. The chopping frequency is much higher than the desired signal bandwidth, and the amount of the undesired signal in the passband of the signal is thereby greatly reduced.
