An interface for use of device whose core circuitry operates in one voltage domain, but exchanges signal with another device (or “host”) according a different voltage domain, and the use of such an interface for supplying data using a double data rate (DDR) transfer, is presented. One concrete example of this situation is a memory card, where the internal circuitry uses one voltage range for its core operating voltages, but exchanges signals with a host using different, input/output voltage range. According to a general set of aspects, the interface receives data signals from the device at the device's core operating voltage domain, individually level shifts these to the input/output voltage domain, and then combines them into a DDR signal for transfer to the host device, where a (non-level shifted) clock signal from the host device is used as the select signal to form the DDR data signal.

An industrial automation system using transformers for providing electrical isolation between a system interface chip and a load interface chip while simultaneously allowing communication of power and data across the isolation barrier. Clock pulses are transmitted from the system interface chip to the load interface chip across one transformer, and the clock pulses are used by the load interface chip to create a power supply for operating the components within the chip. Data is communicated from the system interface chip to the load interface chip across a second transformer by the use of messages. Each message comprises a bit sync field, a byte sync field, and a data field. The bit sync field and byte sync field are used by the load interface chip to synchronize itself with the system interface chip. Transmission and reception of data by the chips are interleaved on a bit-by-bit basis, wherein a bit is transmitted from the load interface chip to the system interface chip after each bit is transmitted from the system interface chip to the load interface chip. After each byte of data is transmitted and received by the chips, the load interface chip eliminates synchronization between the chips, and must resynchronize itself with the system interface chip in order to transmit and receive the next byte of data.

Nucleic acid sequences encoding the bacterial cellulose synthase operon derived from Acetobacter are disclosed. Methods for isolating the genes, vectors containing the genes, and transformed hosts useful for the expression of recombinant bacterial cellulose synthase or production of cellulose are also described.
