摘要： A method of making a composite board and a product made thereby are disclosed. The method includes a lining forming step, a fiber pipe rolling step, a fiber pipe mounting step, a fiber material covering step, and a board body forming step. The product includes a lining acting as a board body, a plurality of long slots formed on the lining, a fiber pipe placed in each of long slots, a foam material mounted in each of fiber pipes, and a fiber material covering an external periphery of the lining. The fiber materials and the fiber pipes are melted and combined together by heat, thereby shortening the operating time. The fiber pipe becomes a reinforcement support structure to increase a structural strength of the composite board, thereby producing a finished product with a light weight and a strong structure.

摘要： A receiver with bypass mode for improved sensitivity is disclosed. An apparatus is provided that includes a non-bypass signal path coupled to a receiver, the non-bypass signal path comprising a filter, a bypass signal path coupled to the receiver, the bypass signal path configure to bypass the filter, and a switch configured to couple an antenna to the non-bypass signal path during time intervals when signals transmitted by a related local transmitter are transmitted with a signal power that exceeds a threshold, and to couple the antenna to the bypass signal path during other time intervals. In another aspect, the switch is configured to couple the antenna to the non-bypass signal path during time intervals when a jamming signal in a selected frequency range is received with a signal power that exceeds a threshold, and to couple the antenna to the bypass signal path during other time intervals.
