Abstract: The present invention discloses a method and a device for handling an exception event in a telecommunication cloud to shorten the notification path and increase the reliability. The method of the present invention includes: detecting a resource state; transmitting a detected resource state exception event to the application layer agent process via a failure notification channel between an infrastructure as a service (IaaS) agent process and an application layer agent process as pre-established inside a host machine Host, and/or transmitting a detected resource state exception event to the application layer management process via a failure notification channel between the IaaS agent process and an application layer management process as pre-established inside the host machine Host. By means of the present invention, the notification path is shortened and the reliability is increased.

Abstract: GNSS signals are centered around two bands, L1 and L2, and antennas must cover both these bands for good RTK performance. GPS is at a lower frequency in both bands than the Russian GLONASS system. What is described herein is a method of constructing a low profile dual frequency wideband antenna with excellent polarization and signal reception for both GPS and GLONASS. This technique minimizes the impact of tolerances of the dielectrics, thicknesses and tuning by optimal construction.

Abstract: A multi-frequency GNSS antenna is provided which can be manufactured from PCB materials and exhibits good multipath rejection. The antenna is capable of receiving RHCP signals from all visible GNSS satellites across a wide beamwidth. A multi-frequency GNSS antenna manufacturing method includes the steps of providing PCB base and support assemblies, first and second feed networks and connecting said first and second feed networks to first and second hybrid connector outputs.

Abstract: An antenna is provided for GNSS and other applications and includes an adjustable-height vertical support PCB mounted on a ground plane and mounting a crossed-dipole radiating arm element assembly. The gain pattern of the antenna can be varied by constructing the vertical support PCB with different heights or adjusting the height and gain pattern in the field. Vehicles with significant pitch and roll can be provided with low-horizon tracking capability by providing a high-profile antenna configuration. Alternatively, low-profile configurations provide steeper gain pattern rolloff at the horizon for maximal multipath rejection and high accuracy. The droop angles of the radiating arm elements are also adjustable for varying the gain pattern and beamwidth. A matching and phasing network is connected to the radiating arm elements and provides a relatively constant input impedance for the various antenna configurations.
