Abstract: A device may receive model information that describes a model and external system information that describes an external system that is different than the model. The model information may identify a first set of signals, associated with the model, that are incompatible with the external system. The external system information may identify a second set of signals, associated with the external system, that are incompatible with the model. The device may generate interface code based on the model information and the external system information. The interface code, when executed, may permit the model and the external system to interact using the first set of signals and the second set of signals. The device may execute the interface code to transform the first set of signals to the second set of signals and to transform the second set of signals to the first set of signals.

Abstract: A dataset including boundary representations of shapes associated with an item being designed for manufacture is accessed by a semantic processing module. A semantic graph of each of the boundary representations of shapes is generated and a numerical processing module computes geometric attributes of each of the shapes. The semantic graph of a shape is updated based on any geometric attributes computed for the shape. The semantic graphs are then compared to a repository of semantic graphs of manufacturing features to identify instances of manufacturing features. Geometric attributes associated with each instance of a manufacturing feature are then computed. For each instance, the associated geometric attributes are compared against a repository of semantic manufacturing rules to determine whether the instance is in compliance with the rules. A user designing the item is alerted to the presence of any instances of manufacturing features that are not in compliance with the rules.

Abstract: Systems and methods for constraining growth in position uncertainty of a mobile device are based on determination that the mobile device is in a pedestrian mode. Determination of the pedestrian mode is based on detection of steps by a pedometer, speed of motion of the mobile device, turn rate determination by a gyroscope, charging condition of the mobile device, availability of satellite signals, etc. Step counts and/or turn rate information are used to ascertain the distance that a pedestrian user may have traversed from a last known position, based on which growth of position uncertainty is controlled.

Abstract: A novel transceiver structure is proposed to increase the achievable data rate for ultra wideband transmitted reference (UWB-TR) systems. For every Ns pulse pairs during one symbol transmission, the data pulses are weighted by one of the M-ary orthogonal sequences, thus carrying additional log2 M-bit information. Furthermore, by utilizing a pair of balanced matched filters before the cross correlator, the minimum separation between the reference and data pulses is significantly reduced without causing any inter-pulse interference (IPI), which in turn reduces the minimum required frame length in order to avoid the inter-frame interference (IFI). As a result, the invented TR system can achieve higher data rates than the conventional TR system, while maintaining superior bit-error-rate (BER) performance even with lower transmit power.

Abstract: A brazed plate heat exchanger (30) is provided for transferring heat between a first fluid (32) and a second fluid (34), with the first fluid (32) being pressurized to a relatively high pressure. The heat exchanger includes plate pairs (41), with each pair (41) defining a plurality of flow channels (56) for the first fluid (32). Each of the flow channels (56) has a hydraulic diameter less than 1 mm. Reinforcements (62) are provided between each of the plate pairs (41) and are aligned with inlet and outlet openings (46,48) to define inlet and outlet manifolds (50,52) for the first fluid (32).

Abstract: A refrigeration system includes a multiple stage compressor 10 having at least two stages 12,14 for sequentially compressing the refrigerant together with a gas cooler 21 connected to the compressor 10 for receiving compressed refrigerant from the last stage 14 of the compressor to cool the same. An evaporator 18 is connected to the gas cooler 21 via an expansion device to receive cool refrigerant therefrom and cool the fluid stream passing through the evaporator 18. A return passage connects the evaporator 18 to the first stage 12 of the compressor and an intercooler 26 is connected between the first stage 12 and the last stage 14 of the compressor to cool refrigerant compressed by the first stage 12 and direct the refrigerant cooled thereby to the last stage 14 for further compression. The intercooler 26 and the gas cooler 21 are integrated into a single unit 22 and receive a single cooling heat exchange fluid and the gas cooler 21 has a larger heat transfer surface area than the intercooler 26.
