Abstract: Computer-implemented methods for training a neural network, as well as for implementing audio encoders and decoders via trained neural networks, are provided. The neural network may receive an input audio signal, generate an encoded audio signal and decode the encoded audio signal. A loss function generating module may receive the decoded audio signal and a ground truth audio signal, and may generate a loss function value corresponding to the decoded audio signal. Generating the loss function value may involve applying a psychoacoustic model. The neural network may be trained based on the loss function value. The training may involve updating at least one weight of the neural network.

Abstract: A portable sign frame adapted to support an indicia-bearing medium includes a pair of elongate side members aligned in a spaced, planar relationship, and at least three brace members extending between and/or rigidly connecting the side members: a top brace member connects the top portions thereof, a bottom brace member that includes a foot support adapted to receive a user's foot connects the bottom portions thereof, and at least one middle brace member that forms a hand support adapted to receive a user's hand extends between the side members at one or more points between the top and bottom portions. At least one mounting site for an indicia-bearing medium is defined, individually or collectively, by one or more of the top portions of the side members, the top brace member, and the middle brace member.

Abstract: A circuit for actuating a switch includes a conductive liquid switch comprising a conductive liquid droplet and a control processor configured to receive a switching signal and configured to provide at least one actuation pulse to the conductive liquid droplet to initiate movement of the conductive liquid droplet based on a duration of a time period between the switching signal and a preceding switching signal.

Abstract: An apparatus performs reliability assessment of electronic hardware. The apparatus includes a test assembly. The test assembly includes at least one programmable logic device (PLD). The PLD is configured to provide a logic function, such as the function of a plurality of inverters coupled in a cascade manner. The apparatus further includes a signal source coupled to the test assembly. The signal source provides a stimulus signal to the test assembly. The apparatus also includes a signal monitor coupled to the test assembly. The signal monitor monitors a response signal generated by the test assembly.
