Abstract: Disclosed aspects relate to methods and apparatus for correcting a first sensor clock of a first sensor. The disclosed methods and apparatus effectuate receiving first and seconds signals in a sensor from a processor at known different times related to the timing of the processor clock. Based on the measured time interval between the times of the first and second signals as determined by the sensor, a clock correction factor may be determined in the sensor for correcting the timing of the sensor clock to be synchronized with the processor clock.

Abstract: Aspects of the invention are related to a method for synchronizing a first sensor clock of a first sensor. The exemplary method comprises: correcting the first sensor clock for a first time, transferring data from the first sensor, and correcting the first sensor clock for a second time, wherein a time interval between two corrections of the first sensor clock is selected such that the first sensor clock is sufficiently aligned with a processor clock of a processor over the time interval.

Abstract: The present teachings provide for an HVAC assembly including a housing and a door. The housing can define a first flue. The first flue can be configured to direct a first airflow through the housing. The door can be received in the housing and can be movable between a first position and a second position. The door can have an edge and an upstream surface. The edge can form a seal with the housing when the door is in the first position. The edge can be spaced apart from the housing when the door is in the second position. The upstream surface of the door can define a plurality of channels proximate to the edge of the door.

Abstract: A device is provided comprising a shared bus including a first and a second line, a first subset of devices and a second subset of devices coupled to the shared bus. The first subset of devices may be configured to operate according to a first protocol mode. The second subset of devices may be configured to operate according to a second protocol mode, wherein the second protocol mode is distinct from the first protocol mode. A first device within the first subset of devices may include a receiver circuit adapted to adjust a signal transition occurring on the first line while the second line is in a first logical state so that the signal transition instead occurs when the second line is in a second logical state. The signal transition is adjusted only if it occurs within a threshold amount of time from a second transition on the second line.

Abstract: A centrifugal blower assembly including a ring-shaped planar portion and a sloped guide surface. The ring-shaped planar portion defines a central aperture at which a centrifugal fan is seated. The ring-shaped planar portion is elevated relative to a lower surface of a scroll casing. The sloped guide surface is between the ring-shaped planar portion and the lower surface of the scroll casing. The sloped guide surface slopes towards the lower surface, and extends in a downstream direction towards a partition of the scroll casing at a scroll starting position of the scroll casing.

Abstract: The present teachings provide for an airflow sound suppressor, such as for an HVAC assembly, for example. The sound suppressor includes a first end configured to be mounted to a first surface of the HVAC assembly. A second end of the sound suppressor is configured to be mounted to a second surface of the HVAC assembly. An elongated portion extends between the first end and the second end. The elongated portion defines a passageway therethrough that extends an entire length of the sound suppressor.

Abstract: This disclosure provides implementations of electromechanical systems resonator structures, devices, apparatus, systems, and related processes. In one aspect, a sacrificial layer is deposited on an insulating substrate. A lower electrode layer is formed proximate the sacrificial layer. A piezoelectric layer is deposited on the lower electrode layer. An upper electrode layer is formed on the piezoelectric layer. At least a portion of the sacrificial layer is removed to define a cavity such that at least a portion of the lower electrode layer is spaced apart from the insulating substrate.
