The disclosed memory cell (10) comprises a graphene layer (16) having controllable resistance states representing data values of the memory cell (10). In one exemplary embodiment a non-volatile memory is provided by having a ferroelectric layer (18) control the resistance states. In the exemplary embodiment, binary '0's and ' 1 ' are respectively represented by low and high resistance states of the graphene layer (16), and these states are switched in a non-volatile manner by the polarization directions of the ferroelectric layer (18).

The present invention relates to methods and arrangements in a relaying radio node and / or in a sending / receiving radio node, adapted for use in a relaying communication system. The relaying node is in bidirectional communication with at least a first and a second sending / receiving radio node, and the relaying radio node receives at least a first signal carrying at least first data and a second signal carrying at least second data. The relaying node generates (215) a reduced representation of at least the first and second signal, with a reduced information content as compared to the first and second data, by a joint non-linearly encoding operation, and transmits (220) the reduced representation to at least the first and the second communication node. The first and second sending / receiving node can extract data from the reduced representation by a non-linear decoding operation (225) using stored a priori information.

A chemical agent detector utilizing surface acoustic wave (SAW) sensors for detecting the presence of a multitude of chemical agents by sampling ambient air is provided. A pressure-differential manifold having an air intake port, an exhaust port, a valve and a pump is used to draw the ambient air into the manifold to be tested. A plurality of SAW sensors mounted on sensor driver boards which are in turn mounted on the manifold come into contact with the ambient air sample. Each SAW sensor is coated with a substance that has an affinity for detecting a particular chemical agent. Each SAW sensor driver board generates a continuous RF signal which emits a frequency shift if a particular chemical agent is detected. A power cycler module turns each sensor driver board on and off such that only one sensor driver board is powered-on at a given point in time. An RF multiplexor receives the continuous RF signals generated by the sensor driver boards and outputs one of the RF signals to a microprocessor based upon a timing signal generated by the microprocessor. The microprocessor interprets the frequency shift as the detection of a chemical agent and provides an alarm that a particular chemical agent has been detected.

The invention provides a turnover kiln with an air distribution system arranged at the bottom. The air distribution system is composed of a kiln body annular interior wall, annular heat suction main air ducts, heat suction branch air ducts, an annular heat sending main air duct, heat sending branch air ducts, moisture discharge openings and a heat sending draught fan desulfuration and dust removing device. By means of opening of a plurality of air brakes fixedly distributed in the heat suction main air ducts and the heat sending main air duct and by means of reasonable joining of air used for drying and roasting in a kiln furnace moving on the annular bottom of the kiln, waste heat can be fully utilized, the aim of conducting artificial drying and one-time palletizing and burning can be achieved, and therefore kiln loading and kiln discharging can be conducted outside the kiln. The air distribution system can thoroughly solve the difficult problem of high-temperature corrosion resistance of the kiln body steel structure and can scientifically and efficiently conduct desulfuration and dust removing, the primer can more easily enter the bottom of the kiln, positive-pressure moisture discharge is achieved, green bodies can be rapidly and evenly dried, unnecessary intermediate process links and devices are omitted, the diameter of the kiln can be large or small, and the turnover kiln is more suitable for small-scale investment and plant construction. The turnover kiln can be specially used for sintering non-bearing air bricks when the diameter of the kiln is small, one and a half times of palletizing and burning can be achieved through natural drying bricks when the diameter of the kiln is large, and the turnover kiln is also suitable for automatic kiln stacking conducted through mechanical hands.
