  • Patent number: 8410414
    Abstract: A fluorescence microscopy imaging system is used for detecting a fluorescence signal of a sample, and includes a module for detecting fluorescence and a module for focusing control. The module for detecting fluorescence includes a fluorescence excitation light source generator (FELSG) and a fluorescence detector. The FELSG is capable of generating an excitation light beam having a first wavelength to excite the sample to emit fluorescence. The fluorescence detector is used to read the fluorescence signal of the sample. The module for focusing control generates a servo light beam having a second wavelength. A servo light beam reflecting film disposed on an observation plane is used to reflect the servo light beam. A return beam signal is analyzed using a focusing detection method. An actuator is used to move the objective for focusing, so as to enable the fluorescence excitation light beam to excite the sample to emit fluorescence.

  • Patent number: 8259066
    Abstract: An impact force feedback device and an interactive system using the same are provided, wherein a large impact force feedback is generated to provide a real force feedback sensation to the user. The impact force feedback device includes a housing, a magnet, and at least one actuator assembly. The housing carries the actuator assembly. The actuator assembly includes a guide rod device, a mass, and a coil. The guide rod device is disposed on the housing. The mass is disposed on the guide rod device in a sliding manner. The coil generates an electric field when a current is conducted through it. An electromagnetic force is generated by supplying the current in a direction orthogonal to a magnetic field. The electromagnetic force is supplied to the mass such that the mass moves on the guide rod device and impacts the housing to generate the unidirectional impact force feedback.
