Abstract: A start method for a photovoltaic rapid shutdown system, an application apparatus and a system. In the method, an inverter system controls the voltage change of a corresponding direct current bus in a photovoltaic rapid shutdown system; and a photovoltaic module shutdown device performs determination according to a measured output voltage of itself, and controls itself to be turned on when the change characteristic of the voltage of the direct current bus connected to itself satisfies a preset turn-on condition. Therefore, merely by means of a self-contained voltage sampling device, the photovoltaic module shutdown device can determine whether a turn-on signal is received, without additionally providing a corresponding receiving device, thereby reducing hardware cost of the photovoltaic module shutdown device while realizing communication between the photovoltaic module shutdown device and the outside.

A side scattering illumination unit performs a first oblique illumination on the to-be-tested sample, so that scattered light of microparticles in the to-be-tested sample forms side scattered light imaging in the imaging unit. A fluorescent illumination unit performs a second oblique illumination on the to-be-tested sample, and excites the microparticles in the to-be-tested sample to emit fluorescence, where the fluorescence forms fluorescence imaging in the imaging unit.

Abstract: An emergency call includes sending, by a Call Session Control Function entity (CSCF) to User Equipment (UE), a session reject message containing indication information indicating re-initiating an emergence call according to a local policy upon detecting that a session request sent by the UE is an emergency session request; and re-initiating, by the UE, an emergency call of CS domain or Internet Protocol Multimedia Subsystem (IMS) domain according to the indication information. A system for an emergency call includes UE and a CSCF. The CSCF includes an emergency call determination unit and an emergency call domain selection unit. Upon detecting that a call is an emergency call, the CSCF instructs the UE to re-initiate an emergency call of CS or IMS domain according to whether a network supports the emergency call of CS or IMS domain.

Abstract: A system for IMS bridging includes an I-CSCF, a BGCF, an S-CSCF and an MGCF; and a method for IMS bridging, including: a caller starting a call, and an I-CSCF routing the call according to a network where the caller locates. According to this invention, the MGCF and S-CSCF can only interwork with entities of the local network. Only the I-CSCF (or via the I-BCF) and BGCF can interwork with entities of external networks. Therefore, this invention can simplify the network and facilitate unified routing management. Alternatively, IP routing may be implemented via the I-BCF only and this also reduces the security risks of the network since the topology information is not exposed.
