Abstract: Methods and system for identifying individual materials from waste streams are disclosed. A request can be received from a requester to assess waste within a waste container. Media in the form at least one of still images or video streams can be accessed from at least one camera located in association with a waste container. The media can be transmitted to an artificial intelligence (AI) platform for processing to determine the class of individual materials contained in the media and provide identification with a confidence level. A data file containing processing results can be created. A response can be generated and transmitted to the requester that initiated the request. The response can include data that further includes all materials found by the AI platform as contained in the media with a confidence level for each and at least one of an identification of the requester, container identification, and container location.

Abstract: The described implementations relate a Passive Optical Network (PON). In one implementation, the PON includes an Optical Network Unit (ONU) that has at least one transmitter subsystem component and an associated optical transmitter. The at least one transmitter subsystem component may be configured to be in an enabled state during a timeslot period assigned to the ONU for transmitting an upstream data burst and a disabled state after the timeslot ends.

Abstract: A power supply circuit is equipped with a converter circuit configured to convert an alternating current signal applied at an input of the power supply circuit into a direct current signal. A control circuit for the power supply circuit is configured to detect a phase of the alternating current signal and to control discharging of an internal capacitive element of the power supply circuit based on the detected phase of the alternating current signal.

Abstract: A control circuit for a switching converter is described herein. In accordance with one embodiment the control circuit includes an analog bus that receives a plurality of input signals and a first set of functional units that are operable to receive at least some of the input signals via the analog bus and to process the input signals to generate digital output data based on the input signals.

At least one functional unit of the second set of functional units is operable to determine switching time instants for the switching converter based on the output data received via the event bus, and the event bus controller includes an arbiter operable to arbitrate data transmission across the bus lines.

Abstract: A flyback converter includes a primary-side switch connected to a primary-side winding of a transformer and a secondary-side switch connected to a secondary-side winding of the transformer. The flyback converter is operated by controlling the primary-side switch to store energy in the transformer during ON periods of the primary-side switch, switching on the secondary-side switch synchronously with switching off the primary-side switch to transfer energy from the transformer to the secondary side, determining an off time of the secondary-side switch based on a reflected input voltage measured at the secondary-side winding when the primary-side switch is on, accounting for a settling time of the reflected input voltage when determining the off time of the secondary-side switch so that the settling time has little or no effect on the off time, and switching off the secondary-side switch based on the off time.
