Abstract: A system and method for generating and providing personalized virtual property tours are disclosed. In some examples, a system provides a virtual property tour that is displayed within an application or a web browser as an interactive open house experience. The virtual property tour enables a user to view an open house virtually through a display of a floor plan, photos of rooms, videos of rooms, three-dimensional tours of rooms, and/or a virtual interactive engagement with rooms. In some embodiments, the virtual property tour is user-directed by selecting a room or other location from a virtual floor plan.

Abstract: A passive, uninterrupted cooling system continues to absorb waste heat generated with a diagnostic medical imaging system during a patient scan, in the event of a power failure incident or disruption of cooling water supply within an imaging facility. The passive, uninterrupted cooling system incorporates one or more phase change materials (PCMs) that maintain the cooling system temperature at material's melting temperature, while absorbing the imaging system's waste heat. This enables clinicians to complete an in-progress imaging scan of a patient within the scanning system's operational temperature specifications. In some embodiments, the PCMs absorb transient heat spikes generated during patient scans, in order to maintain a relatively consistent cooling system operational temperature. In some embodiments, the passive, uninterrupted cooling system is used to cool PET/CT, PET, or CT imaging systems.

Abstract: Methods, apparatus, and systems are disclosed that determine property recommendations for a user. The methods, apparatus, and systems may also predict when a user is likely to become a property buyer and/or seller to determine when certain property recommendations are to be made. The methods, apparatus, and systems use one or more machine learning algorithms to determine a dynamic preference profile for a user that accurately reflects the user and how the user changes over time. The preference profile takes into account property-related information and user characteristic information as variables for the machine learning algorithm(s).

Abstract: Programmable control devices that rely on time-of-day accuracy maintain that accuracy by determining their location via a global positioning system, recording and timestamping continually measured ambient light via a daylight sensor and real-time clock (RTC) of the programmable control device, determining a mid-darkness time point, comparing that mid-darkness time point with a reference mid-darkness time point for the same location for the same day of the year, and then adjusting the RTC of the programmable control device as necessary. Methods of maintaining time of day in a programmable control device are also provided, as are other aspects.

Abstract: A cooling system for cooling a component of an imaging system located in a scan room. The system includes inlet, outlet and return channels. A portion of warm outlet air from a component outlet flows in the return channel to provide warm recirculated air to a mixing zone in the inlet channel. A fan located in the inlet channel draws scan room air into the inlet channel to mix with the warm recirculated air in the mixing zone to form mixed air that flows over the component to cool the component and wherein the mixed air absorbs heat that warms the mixed air to form the warm outlet air. A valve located in the return channel restricts or allows additional warm recirculated air to flow to the mixing zone to mix with the scan room air to maintain a desired control temperature for the cooling system.

Abstract: A fluid coolant system for a gantry of a medical imaging apparatus cools scalable detector electronic assemblies (DEAs) within the gantry. Each DEA includes within its modular housing a first chill plate thermally conductively coupled to cooling detector elements therein and a separate, second chill plate thermally conductively coupled to other electronic components therein, such as electronic circuit boards and/or power supplies. In some embodiments, the first chill plate is oriented between the detector elements and the second chill plate, for thermally isolating the detector elements from other heat dissipating components within the DEA. In some embodiments, coolant flow cascades sequentially through the first chill plate and then through the second chill plate.

Abstract: The present invention provides various aspects of a novel safety light that can be attached to a bicyclist or around the body of an athlete so as to define a well lit, safe distance to avoid collision by a motorist. The present safety concerns would find advantage in an easy to attach safety light that is much larger, more conspicuous and one that provides greater lumens. It would be desirable for athletes and the sports industry if there was provided an improved safety light system to provide a significant warning to let motorists know the safe distance that any motorist and/or his vehicle needs to avoid so as not to hit the cyclist or athlete.
