摘要： An infrared cut filter may be used with an image sensor to remove infrared light components from image light received from a first side of the infrared cut filter prior to the image light reaching the image sensor to be disposed on a second side of the infrared cut filter. The infrared cut filter includes at least one red absorbing layer and an infrared reflector. The at least one red absorbing layer partially absorbs red light components within the image light. The infrared reflector reflects the infrared light components. The infrared reflector is disposed between the red absorbing layer and the first side of the infrared cut filter while the at least one red absorbing layer is disposed between the infrared reflector and the second side of the infrared cut filter.

摘要： An echo cancelling system and method for On Channel Repeater (OCR) used for coverage gap filling, which includes: a splitter, an echo cancellation module, a down-conversion module and a digital signal processor (DSP) module, which uses digital signal processing technologies to achieve a precise echo detection/estimation, and to cancel sufficient part of the echoes in analog domain. The invention may also remove residual echoes in digital domain as well, which is considered to be only a great supplement of the echo cancellation operation in analog domain.

摘要： An approach is provided for communicating in a meshed network including a first terminal and a second terminal. A request from the first terminal for obtaining address information of the second terminal is submitted to a hub. The hub generates a response including the address information and the context information that specifies capabilities of the second terminal. This arrangement has particular applicability to a satellite network (e.g., Very Small Aperture Terminal (VSAT) network) that provides data communication services.
