Abstract: The invention relates to a photodiode array comprising a photodiode and a submount, via which the photodiode is contacted, said photodiode and said submount being interlinked by eutectic bonding. The invention further relates to a method for establishing a link between a first semiconductor element and a second semiconductor element which have different outer contours, the two elements being interlinked by eutectic bonding when already being present as a wafer composite. The two interlinked wafers are subdivided one by one and independently of each other in accordance with the desired outer contour.

Abstract: An optical broadband transmission device for the broadband transmission of data streams between a supply node and a user node. The device comprises an optical fiber for the broadband transmission of data streams between the fiber node and the user node, and a first optical transceiver to the supply node and to the first end of the optical fiber. A second transceiver is connected to the user node and to the second end of the optical fiber. The first and second optical transceiver are designed for transmitting and receiving, respectively, data streams on different optical carrier wavelengths via the optical fiber.

Abstract: A backup power system for a structural appliance normally operated by a primary source of AC current through a primary circuit includes a backup battery; a charging circuit for connecting the primary source to the backup battery and including a battery charger for charging the backup battery; a backup circuit for connecting the backup battery to the appliance and including a converter for converting DC current from the backup battery to AC current for the appliance; and a switch interposed in the primary circuit and the backup circuit for selectively closing the primary circuit and opening the backup circuit during normal operation of the primary source, and for closing the backup circuit upon at least partial failure of the primary source so as to connect the backup battery to the appliance through the converter, whereby the backup battery is charged and isolated from the appliance during normal operation of the primary source, and the backup battery is connected through the converter to the appliance for su
