Abstract: An HVAC thermostat assembly has a wall-plate connector that includes a wall-plate and wire connectors as a whole that allows for a thinner, more aesthetic design. In one instance, the HVAC thermostat includes a display unit with a wall-plate connector recess having a plurality of electrical connector pins extending outward to mate with a wall-plate connector. The wall-plate connector includes a wall plate with incorporated electrical terminals. Other assemblies and systems are disclosed.

Abstract: An air quality measuring device that includes a first chamber, a second chamber, a third chamber, and a fourth chamber. The first chamber includes a first inlet configured to receive a first airflow, a first outlet configured to receive a first portion of the first airflow, and a second outlet configured to receive a second portion of the first airflow. The second chamber includes a second inlet configured to receive the first portion of the first airflow and a first sensor disposed within the second chamber. The third chamber includes a third inlet configured to receive the second portion of the first airflow and a second sensor disposed within the third chamber. The fourth chamber includes a fourth inlet configured to receive the second portion of the first airflow and a third sensor disposed within the fourth chamber.

Abstract: In one instance, a heat sink for thermal management of an electronic component includes a top plate and a base plate that is displaced from the top plate when in an assembled position. The base plate has a first side and a second side, and the second side is for thermally coupling to the electronic component. The heat sink also includes a plurality of fins each including a flat member formed with a plurality of pin apertures and a plurality of fastener apertures. A plurality of pins is disposed through the plurality of pin apertures. The members of the plurality of fins are spaced from one another. The top plate is coupled to a first end of the plurality of pins, and the base plate is coupled to a second end of the plurality of pins to form a secure structure. Other heat sinks are presented.

Abstract: A tray for an HVAC controller includes a tray base, a first mounting tab secured to the tray base and configured to interlock with a corresponding mount of a cabinet of an indoor unit of an HVAC system, a mounting bracket secured to the tray base and comprising an aperture for receiving a mounting screw therethrough, a drip wall that extends up from the tray base, and a cover extending up from the tray base that includes a wall and a top plate. The cover is positioned to protect a component of the HVAC controller from impact when the HVAC controller is installed in the tray.

Abstract: An edge trim for display cases, and methods for making edge trim, are described. Instead of using tape or an adhesive to attach trim to the outer rims of end panels, a shape pattern is created in an extruded trim piece. Then polyurethane liquid can be added to the interior of the panel so that it also fills in the shape pattern. When the polyurethane solidifies into foam it will create a tight bond between the panels and the trim pieces.
