Abstract: An updated operating speed for a fan of an air handler may be determined. The updated operating speed may depend on a target output volume for the air handler and an intermediate resistance value for a filter of the air handler. The intermediate resistance value may be determined by instructing the fan to operate at a first operating speed for a fixed period of time. During the fixed period of time, a pressure sensing system may sense an observed differential pressure measured across the filter. The observed differential pressure may correspond to the intermediate resistance value. The intermediate resistance value may be used to identify, from a set of filter loading values which may be retained in a filter loading data structure, the updated operating speed for the fan such that the air handler is capable of achieving the target output volume.

Abstract: Provided is a door for a cooking appliance, such as an oven range, with multiple spaced apart glass panels. An interlocking mechanism promotes a proper installation of the glass panels, and interferes with the installation of the glass panels or with operation of the appliance if at least one of the panels is not properly installed. A switch with a plunger can be installed in the door, which allows the appliance to operate only when a failsafe electrical circuit is closed corresponding to a selected position of the plunger when the door is closed. The plunger is prevented from retaining that selected position if at least one of the glass panels is improperly installed or if a top cap is not properly seated or installed above the glass panels.

The flow control device further includes a drive unit attached to the damper assembly, the drive unit selectively moving the damper assembly between a closed position in which the damper assembly blocks a flow of the exhaust gas through the outlet duct and an opened position. The oven further includes a control system for controlling the damper assembly.

Abstract: A data center row infrastructure module enables rapid deployment of a computing room enclosure for computer systems that provides intake air circulation to, and exhaust air removal from, the computer systems in the enclosure. The data center row infrastructure module includes free-standing exhaust plenum structures encompassing opposite sides of the enclosure and a plenum module spanning a top end of the enclosure between the free-standing exhaust plenum structures. Each free-standing exhaust plenum structure includes an internal exhaust air plenum that directs exhaust air received from the enclosure through an exhaust air outlet on a top end of the free-standing exhaust plenum structure. The plenum module establishes a bottom end of a cooling air plenum above and separate from the enclosure and between the free-standing exhaust plenum structures. Some plenum modules can direct cooling air directly to the enclosure as intake air.

Abstract: A portable analytic apparatus is provided that is capillary-driven and capable of detecting analytes within a sample and providing an unambiguous positive/negative response. Embodiments provide for a hydrophobic detection reagent within a hydrophilic porous media, where a hydrophobic detection reagent changes to hydrophilic products in a presence/absence of a target analyte. This change from hydrophobic to hydrophilic provides a means to achieve a desired result of generating an unambiguous qualitative and/or quantitative positive/negative readout by forcing samples to wick at differential rates through hydrophilic regions towards a detection region. Suitable hydrophobic detection reagents are also provided.

Abstract: A method of controlling seismic data acquisition includes synchronizing a sampling rate of at least one node configured to acquire seismic data with a GPS timing signal from a first GPS seismic device; and delaying sending a start signal to one or more seismic sources, the delay being with reference to a GPS timing signal from a second GPS device.

Abstract: An inverted exhaust plenum module exhausts air from an enclosure into an ambient environment while mitigating airflow restrictions caused by ambient wind conditions, particularly headwinds impinging on exhaust vents. The plenum module includes wall elements that extend downwards from separate edges of two separate roof elements of the enclosure, forming a plenum between the wall elements that is open at the top. Exhaust vents in the wall elements exhaust air from the enclosure into the plenum to circulate into the ambient environment via the top of the plenum. By exhausting air into a plenum that extends beneath roof elements, the vents are at least partially obscured from ambient winds that might otherwise impinge on the vents. A wing element can be installed to induce exhaust airflow via lowering air pressure at the top of the plenum. The plenum module can be a separate module that is coupled to a structure.
