Abstract: A reference transistor forms part of a measurement circuit coupled to bias control circuitry that is configured to operate a primary transistor at a desired operating point by providing appropriate DC bias voltages to the control terminal of the primary transistor and one or more current terminals of the primary transistor based upon an output of the measurement circuit generated using the reference transistor. A dissipative circuit element is electrically coupled to the reference transistor and is configured to cause the reference transistor to exhibit negative gain at a drain terminal (or other output node) of the reference transistor with respect to alternating-current (AC) electrical signals which may be unintentionally coupled to the gate (or other input node) of the reference transistor.

Abstract: A method includes selecting a landing waypoint on a runway and selecting a starting waypoint based on a location/heading of an aircraft relative to the runway. The method includes selecting additional waypoints between the starting waypoint and the landing waypoint. The starting and additional waypoints include latitude, longitude, and altitude variables. A sequence of waypoints from the starting waypoint to the landing waypoint via the additional waypoints indicates a desired location for the aircraft to traverse. The method includes generating location constraints for the starting and additional waypoints and generating an objective function for optimizing at least one of the variables. Additionally, the method includes generating a solution for the objective function subject to the location constraints. The solution includes latitude, longitude, and altitude values for the variables.

Abstract: A method of adaptive persistence forecasting includes receiving historical load values for a site with at least one component that consumes energy; receiving historical temperature values corresponding to dates of the historical load values; evaluating the historical load values and the historical temperature values to determine a correlation coefficient; determining that there exists at least a threshold correlation between a load activity and temperature for the historical load values and the historical temperature values based on the correlation coefficient; in response to determining that there exists at least the threshold correlation, normalizing the historical load values based on a set temperature; and applying an adaptive seasonal persistence model to the normalized historical load values to output a forecast for use in controlling energy resources at the site.

Abstract: Read events capturing parcel information as a parcel is transported through a facility is received, and a configuration file mapping readers capturing the read events to workspace locations within the facility is accessed. Utilizing the read events and configuration file, one or more locations are determined for a parcel being transported through a facility. The locations may form a most likely path, or sequence of locations, through the facility. The determined locations may be utilized for generating one or more graphical user interface elements for tracking parcel and/or other operational aspects. For example, a graphical user interface may indicate errors, such as errors in the parcel's path and slowdowns, detected from the read events. Additionally, volume of parcels over time may be determined from the read events. Further, a graphical user interface may indicate employee performance based on errors and/or read events attributed to the employee.

Abstract: A surface cleaning head with dual rotating agitators (e.g., a leading roller and a brush roll) may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The leading roller is generally positioned adjacent to and in advance of the opening of the suction conduit. The rotating brush roll may be located in the suction conduit with the leading roller located in front of and spaced from the brush roll, forming an inter-roller air passageway therebetween. The leading roller may provide a softer cleaning element than the brush roll and may also have an outside diameter that is less than the outside diameter of the brush roll. The surface cleaning head may also include debriding protrusions contacting the leading roller and/or a leading bumper that extends in front of the leading roller.

Abstract: A device having a reference transistor fabricated within the same semiconductor substrate as a primary transistor (e.g., configured for use in a radiofrequency amplifier or other active circuit) has a shared metallization area coupled to a current terminal of both transistors configured to shield a control terminal of the reference transistor from coupling of alternating current interference from alternating currents within the primary transistor.

An inductance value of the inductor of the harmonic control circuit and a capacitance value of the capacitor of the harmonic control circuit are selected to terminate second order harmonic components of a fundamental frequency of a signal generated by the carrier amplifier.
