Abstract: HVAC control system's supervisory control is crucial for energy-efficient thermal comfort in buildings. The control logic is usually specified as ‘if-then-that-else’ rules that capture the domain expertise of HVAC operators, but they often have conflict that may lead to sub-optimal HVAC performance. Embodiments of the present disclosure provide a method and system for optimized Heating, ventilation, and air-conditioning (HVAC) control using domain knowledge combined with Deep Reinforcement Learning (DRL). The system disclosed utilizes Deep Reinforcement Learning (DRL) for conflict resolution in a HVAC control in combination with domain knowledge in form of control logic. The domain knowledge is predefined in an Expressive Decision Tables (EDT) engine via a formal requirement specifier consumable by the EDT engine to capture domain knowledge of a building for the HVAC control.

Abstract: A standalone drum-mounted lint filter for a washing machine is provided. The filter includes a filter housing including a plurality of inner walls dividing the filter housing into a plurality of filter chambers, each filter chamber defining at least one inlet configured to allow wash water to flow into the respective chamber. The filter further includes at least one retainer barrel arranged within each filter chamber and configured to retain lint during operation of the washing machine. The filter also includes a porous removable filter cover defining front-facing outlets open to the drum, allowing for exit of the wash water back into the wash.

Abstract: A voltage regulator includes a first circuit to generate a difference signal based on an input reference voltage, a regulated output voltage, and a signal on a feedback node. The voltage regulator includes a second circuit to provide the regulated output voltage on the output node based on the difference signal. The second circuit includes a first transistor coupled to receive the difference signal, a first feedback circuit to provide a first feedback signal to the feedback node, and a second feedback circuit to provide a second feedback signal to the feedback node. An open loop frequency response of the voltage regulator has a first pole and a second pole and the first feedback signal may adjust the frequency of the second pole based on a load current. The second feedback signal may adjust loop gain based on the load current.

Abstract: A repair boot for an air intake assembly having an air intake duct. The repair boot is open between its ends and has a collar with a first interior dimension that is selected to complement the air intake duct and a second interior diameter that is selected to engage a surrounding flange on the exterior of air intake duct.

Abstract: Methods and systems are provided for testing three-dimensional (3D) stacked dies of integrated circuits (ICs). The methods and systems receive, by test signal routing logic implemented on a first die, a first die test signal, the test signal routing logic operating in an elevate mode or turn mode. The methods and systems receive a second die test signal from a second die and route the first die test signal to an external device in the turn mode. The methods and systems route the second die test signal received from the second die to the external device in the elevate mode.

Abstract: A dongle for setting the position of a throttle plate in a throttle body has a process that is driven by a power supply regulated to 5 Vdc to generates a graphic representation of an acceptable range for engine revolutions per minute and throttle plate position within a throttle body. A comparator extracted information from an interrogation of the engine control monitor to determine if the throttle body is within the acceptable range. A signal is generated to indicates the presence or absence of an acceptable range.

Abstract: Various examples are provided related to fault detection of power converters. In one example, a method includes sensing phase currents of a three-phase transformer; determining a centroid vector in an alpha-beta stationary reference frame based upon averaged values of the sensed phase currents; identifying a fault on a side of the transformer based upon a location of the centroid vector within the alpha-beta stationary reference frame, the location defined by a magnitude and an angle of the centroid vector; and adjusting operation of the power converter in response to the identified fault. In another example, a power converter includes a three-phase transformer connected between primary and secondary side three-phase bridges and control circuitry that can determine a centroid vector based upon sensed phase currents; identify a fault on a side of the three-phase transformer; and adjust operation of the power converter in response to the identified fault.

Abstract: A mapping system may include a display, a global positioning satellite (GPS) system to be carried by a vehicle and a controller. The controller is configured to determine a polygon representing a geographic boundary of a first region based on signals received from the GPS system of the vehicle as the vehicle travels to enclose the first region, to estimate geographic coordinates of a first number of consecutive rows within the polygon based on signals from the GPS system of the vehicle as the vehicle travels between a second number of consecutive rows less than the first number of consecutive rows and to output control signals causing the display to present a map comprising the polygon and lines within the polygon, the lines being based on the estimated geographic coordinates of the first number of consecutive rows.

Abstract: A spring-loaded hinge assembly including a hinge support bracket and a leaf that is pivotally mounted to the hinge support bracket. A coil spring is supported on a spring support member, which includes a pivot bush. The coil spring applies a biasing force to the spring support member, which operates to push the pivot bush against a cam on the leaf. A lock configured to rotate between locked and unlocked positions includes a finger that engages an engagement feature on the hinge support bracket when the lock rotates to the locked position as the leaf swings toward the open position. In the locked position, the lock holds the coil spring in a partially compressed, pre-load condition and the pivot bush at a partially retracted position relative to the cam until the lock is subsequently released by contact between the cam and the pivot bush during subsequent closure.

Abstract: An example method and system for sharing an output device between multimedia devices to transmit and receive data, is provided. The method includes operations of automatically discovering one or more second multimedia devices, when a first multimedia device is positioned within communication range of the one or more second multimedia devices that transmit a low power signal; and transmitting data of the first multimedia device to the one or more second multimedia devices, when the one or more second multimedia devices are discovered.

Abstract: A contactless laundry treating apparatus may include a cabinet having a front panel defining an access opening configured to receive laundry items, door attached to the front panel via a hinge assembly, where the hinge assembly may include a hydraulic system arranged on an interior of the front panel within the cabinet configured to engage with a connecting hook arranged within the door to selectively apply an outward force on the connecting hook to open the door and an inward force on the connecting hook to close the door.

Abstract: Systems, methods and computer program code are provided to select a payment gateway for use in a transaction which include receiving information identifying the transaction, identifying a set of available payment gateways, calculating a success probability associated with each payment gateway in the set of available payment gateways, selecting the payment gateway having the highest success probability, and causing the transaction to be processed using the selected payment gateway.

Abstract: An IC chip test engine selects an instrument of an IC design based on an instrument access script, wherein the selected instrument comprises an IP block and a test data register (TDR) logically arranged upstream from the IP block. The IC chip test engine can also identify a set of SIBs gating access to the selected instrument and select a scan chain for operating the set of SIBs to control access to the selected instrument. The IC chip test engine augments the scan chain with data to cause at least a furthest downstream SIB of the set of SIBs that gates access to the selected instrument to transition to an opened state. The IC chip test engine can generate a set of load vectors for the scan chain to load the TDR of the selected instrument with data to apply a respective test pattern to the IP block.
