Abstract: A general wireless mesh network of communication devices with packet message transmission, especially for telemetry and automation, includes at least a single control communication device and a set of slave communication devices. The control communication device searches in the network and assigns a virtual routing number to each slave communication device. The virtual routing number reflects a distance of the slave communication device from the control communication device, expressed by the number of routings, and is stored in the slave communication device. The slave communication device, for further routing of packets in the mesh network, uses time slots assigned according to the difference between said virtual routing number and the virtual routing number of the sender of a received packet. Packet routing is based on successive flooding of the virtual routing structure and time division multiplexing.

Abstract: A temperature control system includes a compressor, a condenser, an evaporator, a receiver, and an accumulator. A valve is positioned between the evaporator and the receiver. An evacuation line has a first end in fluid communication with heat transfer fluid between the valve and the receiver, and a second end in fluid communication with the accumulator. The evacuation line provides for flow of the heat transfer fluid from both of the first heat exchanger and the receiver to the accumulator during an evacuation mode of operation of the temperature control system. The valve can take the form of a check valve or an expansion valve without a bleed port.

Abstract: A temperature control system for a container includes a refrigeration circuit having a primary fluid circulating therein and a secondary fluid circuit in communication with a first compartment of the container and a second compartment of the container. The secondary fluid circuit has a secondary fluid separate from the primary fluid circulating therein.

Abstract: The invention filed involves a method of coding and/or decoding binary data for wireless transmission, particularly for radio transmitted data. A sequence of binary data, introduced at the entry to the coding machine with a class N coder (KOD) comprising a register (REG), a comparator (COMP) and a counter (CITN), where N is a number greater than or equal to 3, is separated into a sequence of binary data of the same value, so that the length of each such sequence is not less than one and not more than N, and so that the binary values of the data introduced at the entry to the coder (KOD) are compared with the value last received and recorded in it, the lengths of the same sequences at this entry are read up to the number N and, after reading to N, a sequence of binary data of a value opposite to the value at the entry to the coder (KOD) is inserted, this inserted data sequence having a length M, where M is a number greater than or equal to one and less than N.

Abstract: The output shaft (8) of the electric motor swings first to one end stop, the direction of the rotation of the motor then changes, whereupon the output shaft (8) is returned at a constant speed to the opposite stop, whilst in the same pre-selected constant time intervals its angular position is measured between the two stops. Taking into account the size of the angle between the two stops, the measurement data on the angular position are converted into angle increments in individual, measured, constant time intervals and a calibration curve is thus made of tile specific sensor used for measuring the angular position of the output shaft (8) of the motor.

Abstract: A method of controlling a compressor in a transport temperature control unit having a prime mover providing power to the compressor. The compressor has a power requirement that varies depending on loading conditions. The method includes determining the maximum power available from the prime mover, determining the power requirement of the compressor, and adjusting the loading conditions of the compressor so that the power requirement of the compressor substantially equals the maximum power available from the prime mover. Preferably, the method includes starting the compressor at a low speed, varying the suction pressure as permitted by the maximum amount of power available until the suction pressure reaches a maximum suction pressure setting, and after the suction pressure reaches a maximum suction pressure setting, increasing the speed of the compressor as permitted by the maximum-amount of power available.
