Augmented reality assisted pickup
A network system, such as a transport management system, uses augmented reality (AR) to identify an approaching vehicle. Responsive to receiving a trip request, a trip management module matches the rider with an available driver and instructs a trip monitoring module to monitor the location of the driver's vehicle as it travels to the pickup location. When the driver's vehicle is within a threshold distance of the pickup location, an AR control module instructs the rider client device to begin a live video stream and instructs an image recognition module to monitor the video stream for the driver's vehicle. Responsive to the driver's vehicle entering the field of view of the camera on the rider client device, the AR control module selects computer-generated AR elements and instructs the rider client device to visually augment the video stream to identify the driver's vehicle as it approaches the pickup location. |

Chopped bias magnetic field solid-state spin sensor for low frequency measurements of physical quantities
Applying a bias magnetic field to a solid-state spin sensor enables vector magnetic field measurements with the solid-state spin sensor.

This makes the resulting solid-state spin sensor system suitable for detecting low-frequency (mHz, for example) changes in magnetic field or other physical parameters. |

Forecast-based automatic scheduling of a distributed network of thermostats with learned adjustment
Heating and cooling systems at various geographical locations are controlled by a central energy management service unit to maintain comfortable indoor temperatures. In some weather conditions, people may intuitively prefer a slightly warmer or cooler indoor temperature. In systems equipped with environmental learning capabilities, an apparent outdoor temperature is determined based on the geographic location itself, the season at the geographic location, the forecasted actual temperature, and one or more seasonal weather factors such as wind velocity or humidity. The apparent temperature and a trained machine learning system are used to select an automated schedule for the geographic location to be directly transmitted to devices at the location. The automated schedule can vary from typical schedules by causing the heating and cooling systems to maintain a temperature that is slightly warmer or cooler than typical indoor temperatures. |

Genetically modified trehalase-expressing yeasts and fermentation processes using such genetically modified yeasts
The present invention relates to genetically engineered yeasts having a heterologous trehalase gene and fermentation processes for using such yeasts. The yeasts can express trehalase in a quantity sufficient to convert significant amounts of trehalose to glucose, thereby improving the yield of the product in a fermentation, and/or reducing or eliminating the need to add exogenous trehalase to the fermentation. The yeasts can also include other heterologous genes for expressing enzymes useful for improving yield and/or for reducing or eliminating the need to add exogenous enzymes to the fermentation. |

ABCA1 downregulation in prostate cancer
A method of providing a prognosis or diagnosis of prostate cancer in a subject is described. The method includes obtaining a urine or prostate sample from the subject; determining the level of expression of ABCA1 in the sample; and comparing the level of expression of ABCA1 in the sample to the level of a control sample, wherein a decreased level of ABCA1 expression compared to the control indicates the subject has prostate cancer or a more severe form of prostate cancer. Methods of treating subjects identified as having prostate cancer, and kits for carrying out the method of prognosis or diagnosis are also described. |
