Abstract
A gateway node provides an interface connectivity between communication networks. The gateway node is configured to be operably connected to another gateway node as well as to a base station providing connectivity for a plurality of mobile terminals over a radio interface. Further, the gateway node is configured to send a first peer status report message indicating the respective status of a group of functions of the gateway node which are predetermined to be vital to an application connectivity over the gateway node of selected ones of said plurality of mobile terminals. The first peer status report message is sent periodically.
Claims11
Projector comprising
- a laser light source (16),
- modulation and projections means for modulating the light from said laser light source (16) and projecting said light into a direction within a projection region to generate a projected image (12) filling said projection region,
- and means for projecting an alerting image (22) into a direction of an alerting region (20) outside of said projection region (12), where the alerting light used for generating said alerting image (22) is of a wavelength visible to the human eye, and of an intensity of eye-safe level.
Method for operating a projector, where
- laser light is generated and projected into a direction of a projection region (12) to generate a projected image (12) filling said projection region,
- and an alerting image (22) is projected into a direction outside of said projection region,
- where the alerting light used to generate said alerting image (22) is of a wave length visible to the human eye, and of an intensity of eye-safe level.
