Iteratively trained machine learning models for evaluations of internal consistency
Disclosed is an approach for evaluating internal consistency of object classifications using machine learning modeling. In an example, models are iteratively trained, using supervised learning, on different majority segments (e.g., about 90%) of a dataset as training data segments. Trained models can be applied to the remaining data (e.g., about 10%) as test data segments to obtain, for each object, a predicted classification and a confidence score. Models in training iterations (e.g., 10 iterations) may be independently trained on substantially non-overlapping test data segments (with each iteration testing, e.g., about 10% of the dataset). When a model's predicted classification disagrees from a prior classification, and the confidence of the prediction is sufficiently high (indicating sufficiently strong disagreement), the object's prior classification may be revised. Training data, other than the data itself being evaluated for consistency, is not necessarily required. |

Direction finding technique in radar array signal processing
This invention describes a new Direction Finding (DF) algorithm named as Braided Array Sampling via an Inter-Channel Scheme (BASICS) that can enhance estimation accuracy of the direction of arrival (DOA) to a higher level than existing algorithms. With appropriate analogical reasoning, it can be applied to all kinds of radars and antennas. It breaks the ordinary belief that an array of N antennas can only generate N pictures of spectral for analysis. Without the need of improvement on the system hardware, BASICS assumes many virtual movements of array antenna in order to produce enough linear equations describing Doppler modulations of targets' spectra by those of the virtual movements, and the solutions would give accurate DOA information of possible targets. This invention presents the principle of BASICS and its theoretical supports, as well as the basic conditions to apply BASICS. |

Nervous system-specific transmembrane proteasome complex that modulates neuronal signaling through extracellular signaling via brain activity peptides
The inventors surprisingly found that neural stimulation caused the synthesis and degradation of proteins into peptides which were then secreted into the cell media within minutes of stimulation by a novel neural-specific and membrane bound proteasome (neuronal membrane proteasome or NMP) that is transmembrane in nature. These secreted, activity-induced, proteasomal peptides (SNAPPs) range in size from about 500 Daltons to about 3000 Daltons. Surprisingly none of the peptides appear to be those previously known to have any neuronal function. Moreover, these SNAPPs have stimulatory activity and are heretofore a new class of signaling molecules. Moreover, the NMP appears to play a highly significant role in aspects of neuronal signaling known to be critical for neuronal function. The inventors have gone on to develop all tools to study this novel mechanisms including protocols and practice for generation and purification of SNAPPs as well as a new and specific inhibitor of the NMP allowing for selective control of this process in the nervous system.

Guidance audio cues for navigation assistance
In device-assisted navigation, audio navigation cues are often presented at particular locations along a route (e.g., “in 200 meters, turn left” and “turn left here”). However, if the user stops, navigation cues also stop since the user's position is not changing. Additionally, the navigation instruction at the next navigation point may be conflated with the actual position of the next navigation point; e.g., an instruction to “turn left” may be confusing if the road takes a sharp right turn immediately before the next navigation point. Instead, the device may periodically compare the current position of the user and the next navigation point, and periodically present guidance audio cues that indicate the distance and heading offset to the next navigation point. Guidance audio cues may be integrated with and/or supplemented by audio navigation instructions to indicate both the location of the next navigation point and instructions to be followed there. |

The vapor pump, actuated by the high pressure refrigerant in gaseous form provided by the burst compressor, is configured to pump a combination of gaseous, vaporous and liquid refrigerant out of the receiver tank and inject that low pressure refrigerant mix into the burst compressor, where it is heated to change the state of the refrigerant to a heated, pressurized gas. Then the heated, pressurized gas is released in bursts into the other components of the vapor compression cycle. Thus, embodiments of the present invention use heat to provide cold. Because of this arrangement, vapor-compression systems constructed and arranged to operate according to embodiments of the present invention are able to provide air-conditioning and/or refrigeration much more efficiently and with much less expense than traditional vapor compression systems for air-conditioning and refrigeration. |

No motion friction between the driver and the rocker arm shaft, and the dedicated driving cam separating from the main piston when the driver is not in operation effectively reduce wear and noise between the dedicated driving cam and the main piston and improve engine power utilization. When the driver is in operation, the dedicated driving cam automatically adjusts a driving valve through a hydraulic gap, and a driving lift is not affected by an initial gap setting. The driving oil circuit is automatically drained once per revolution of a positive power cam, thus, a circulating flow of oil may not cause accumulation of impurities when the oil is too dirty, which improves working stability and reliability. |
