Abstract: A service data management method and apparatus for service building blocks (SBB), a device and a storage medium are provided, and a service data setting interface is extended. When service data needs to be set, the service data is received through the service data setting interface, and service data to be set is added into a service data set of a service corresponding to service identification information according to the service identification information and the service data to be set in the service data setting instruction. When it is detected that an SBB needs to be configured with the service data, service data corresponding to the SBB in the service data set corresponding to the SBB is directly configured for the SBB, i.e., the set service data takes effect immediately and is able to be called by the corresponding the SBB in real time.

Abstract: A photoacoustic catheter includes an elongated catheter body and a housing positioned near a distal end of the elongated catheter body. A length of multimode fiber extends through the elongated catheter body and has a distal end that is beveled at about 45° relative to a longitudinal axis of the multimode fiber and is positioned in the housing. An ultrasonic transducer, electrically connected to an electrical wire extending along the elongated catheter body, is positioned within the housing. A mirror element is also positioned within the housing and includes a mirror surface beveled at about 45° relative to the longitudinal axis of the multimode fiber. The catheter is operable to deliver an optical wave through the multimode fiber and to deliver an ultrasonic wave collinearly from the housing and out of an aperture of the housing to obtain optical data and ultrasonic data within a mammalian luminal organ.

Abstract: The present invention provides a gas measuring method based on photothermal effect in hollow-core optical fiber comprising: filling a target gas into the core of a hollow-core optical fiber; coupling a probe light and a periodically modulated pump light into the hollow-core optical fiber; absorbing the pump light by the target gas resulting in the periodic modulation of the phase of the probe light; demodulating the phase modulation information of the probe light to obtain the concentration of the target gas, wherein the pump laser is wavelength and/or amplitude modulated. In the present invention, two lasers including a pump laser and a probe laser are used for the measurement, this approach is simple and practical.
