    摘要: Novel fabric conditioning agents which contain either an ester or a NH link between a glyceric carboxyl group and a quaternary ammonium group are described. The compounds based on glyceric acid are both effective fabric conditioners and biodegradable, and may be formulated in any conventional physical form to form a fabric conditioning composition. A method of using the composition is also described.

    摘要: A data conversion circuit is provided. The data conversion circuit includes a transceiver that can receive a first data channel in a first or second data format and convert it into a second data channel having a third data format. The transceiver can also receive data from the second data channel in the third data format and convert it into the first data channel in the first or second data format. The data conversion circuit includes a bus interface that is connected to the transceiver. The bus interface transfers data between the transceiver and a bus control module. The data conversion circuit also includes an onboard controller interface that is connected to the bus interface. The onboard controller interface transfers data between the transceiver and an onboard controller.
