Open input empathy interaction
A chatbot capable of empathic engagement with a user is disclosed. An identified trend in a user's mood or goals between a first time and a second time can be associated with open input (e.g., open text string input) from the user. As the user's mood or goals continue to be tracked, a subsequent trend can be identified that is the same as, similar to, different from, or opposite to the first identified trend. The user can then be automatically engaged based on the open input associated with the first identified trend. In an example, a user may input thoughts or reasons why they have been having a positively trending mood over a duration of time. The chatbot can then repeat or otherwise use those same thoughts or reasons to engage the user empathically when the chatbot detects that the user is experiencing a negatively trending mood. |

Imaging and radar fusion for multiple-object tracking
This document describes methods and systems directed at imaging sensor and radar fusion for multiple-object tracking. Using tracking-by-detection, an object is first detected in a frame captured by an imaging sensor, and then the object is tracked over several consecutive frames by both the imaging sensor and a radar system. The object is tracked by assigning a probability that the object identified in one frame is a same object identified in the consecutive frame. A probability is calculated for each data set captured by a sensor by a supervised-learning neural-network model using the data collected from the sensors. Then, the probabilities associated with each sensor are fused into a refined probability. By fusing the data gathered by the imaging sensor and the radar system in the consecutive frames, a safety system can track multiple objects more accurately and reliably than using the sensor data separately to track objects. |

Imaging biomarkers based on ratio between diffusion and perfusion
The ratio of arterial spin labeled (ASL) perfusion to diffusion weighted imaging (DWI) is generally homogeneous in the anoxic/hypoxic injury population. Conversely, the ratio is more heterogeneous in the non-anoxic/hypoxic population. By plotting these ratios in a graphical format in the form of an axial color map of the brain—referred to as a normalized diffusion to perfusion (NDP) ratio colormap—it may be determined whether a patient has suffered from an anoxic/hypoxic injury. Thus, the anoxic and non-anoxic injury patients will have, respectively, homogenous and heterogeneous color maps. Anoxic brain injury patients have a global homogeneously positive relationship between qualitative ASL perfusion and diffusion weighted signal such that areas of restricted diffusion show significantly increased ASL perfusion signal, which may be attributable to BBB integrity. The NDP ratio colormap provides an imaging biomarker to differentiate anoxic brain injury from normal controls and to potentially assess BBB integrity. |

Receptor response modulation method, and measuring device using receptor response modulation
In an analysis of a fluid component using a nanomechanical sensor covered with a receptor, the same receptor is caused to express different response characteristics. In a measuring system of analyzing a response when a sample gas and a purge gas are supplied to a nanomechanical sensor while switching the sample gas and the purge gas, a gas (external gas) different from both gases is mixed into a gas channel and supplied to the sensor for measurement. Since a response characteristic of a receptor is modulated by mixing of the external gas, the object described above is achieved. |

Method of sample preparation for maldi and automated system therefor
Methods for preparing a biological sample for testing by Maldi where such methods are selected based on sample parameters. Maldi scores are obtained for a range of sample parameters (e.g. McFarland, dispense volume and number of dispenses). From the data, sample preparation parameters can be selected for a biological sample being prepared for Maldi testing. One sample preparation strategy uses multiple dispenses of sample with an intervening drying step, which yields more accurate Maldi scores, particularly for samples at the low range of McFarland values (e.g. below about 2). |

Active grinding media for processing samples
An active/resilient grinding media inside a tube containing a sample is oscillated rapidly by a homogenizer so that the active media is driven in a first direction until it impacts a first end of the tube, which causes it to deform and store an energy charge as it decelerates and stops, and it then accelerates rapidly in the second opposite direction under the discharging force of the stored energy toward the opposite second end of the tube. This cycle of the active media decelerating/charging and then discharging/accelerating is repeated throughout the entire oscillatory processing of the sample. The result is much higher velocities of the active media and therefore much greater impact forces when the sample and active media collide, producing increased efficiency in disruption and size-reduction of the sample particles. |

Method for the indirect evaluation of pre-charge air pressure in a diaphragm-type or bladder-type expansion tank
Setting and maintaining proper pre-charge air pressure in a diaphragm or bladder-type expansion tank of any fluid system is essential for safe and efficient operation of that system. In usual practice, pre-charge air pressure checks are done by emptying the system of fluid and connecting an analog air gauge to the air input of the expansion tank. In this invention a pressure sensor that is permanently coupled to the fluid volume of the expansion tank is used to also evaluate the pre-charge air pressure in the tank. By employing a single sensor for both fluid and pre-charge air pressure evaluation, the problem of inconsistent calibration between fluid sensing and air pre-charge measuring devices is eliminated. Using the same permanently installed sensor for every test or adjustment in a given system eliminates the problem of variations in calibration between different sensors or gauges used at different testing times. |
