Abstract: A refrigeration system includes a low temperature (LT) compressor, a medium temperature (MT) compressor having a suction side fluidly coupled with a discharge side of the LT compressor, a low temperature evaporator, and a medium temperature evaporator. Refrigerant from the low temperature evaporator is returned to a suction side of the LT compressor and refrigerant from the medium temperature evaporator is returned to a connection point downstream of the discharge side of the LT compressor and upstream of the suction side of the MT compressor. The refrigeration system performs a defrost cycle by directing warm refrigerant from the suction side of the MT compressor to pass through the low temperature evaporator in a reverse direction. The warm refrigerant is drawn from a position downstream of the connection point and upstream of the suction side of the MT compressor and returned to the suction side of the LT compressor.

Abstract: A method for defrosting an evaporator of a refrigeration system includes providing a refrigeration system including a low temperature (LT) compressor, a medium temperature (MT) compressor, a low temperature evaporator, and a medium temperature evaporator. The method includes initiating a defrost cycle for the refrigeration system by closing a return valve to shut off refrigerant return to the LT compressor from an outlet of the low temperature evaporator and opening a defrost supply valve to define a fluid flow path between a suction side of the MT compressor and an outlet of the low temperature evaporator. The method includes operating the LT compressor and the MT compressor such that warm refrigerant from the suction side of the MT compressor is provided through the low temperature evaporator and returned to a suction side of the LT compressor through a hot gas tank.

Abstract: A device for use by a dental patient fits in the patient's ear and has at least one curved resonator tube to reduce the perceived volume of a dental drill. The device can have multiple layers of resonator tubes and a port into which recorded music can be played to calm the patient further.

Abstract: Architecture presents in a display related content in association with (an annotation) a social media post, as derived from post information of the social media post itself. The related content can be presented in the user interface proximate the social media post or elsewhere in the user interface. The related content can be presented as search engine queries, images, videos, and/or links to related websites. More specifically, the disclosed architecture facilitates the automated annotation of a social media post with related content derived from: post information such as a URL (uniform resource locator) referred to in the social media post, post information such as the text, image(s), and/or video content in a social media post itself, and post information such as content linked-to by a URL referred to in a social media post.

Abstract: A unique system and method facilitates analyzes searches or queries that are geographic based. In particular, a user can submit a geo-tag based search for items posted on a listing service according to the item's location or geo-tag information. The geo-tag information for each item can be approximate such as the city, state, or zip code or more specific such as the street address where the item is located. The amount of geo-tag information disclosed to any other user can depend on the type of item being offered. Geo-tag information is analyzed to facilitate determining item matches. In addition, users that post items can employ query results to analyze the quality of their items such as from the buyer's perspective.

Abstract: A unique system and method that facilitates searching for items offered for sale or otherwise in an online classifieds environment. The system and method involve allowing a user to search for such items according to the item's location or geo-tag information. The geo-tag information for each item can be approximate such as the city, state, or zip code or more specific such as the street address where the item is located. The amount of geo-tag information disclosed to any other user can depend on the type of item being offered. One or more geo-tagged items can be returned in response to a query. The items can be returned in a list or a map format wherein the items can be pinpointed according to their locations. The map of the area around and near the item's location can provide useful information to the user to facilitate determining which item(s) to pursue.
