Accordingly, the instrumentation amplifier is capable of accommodating a high voltage range of common mode voltages while still providing controllable gain.

Abstract: This document describes methods for pretreating coal to create either a dried coal or a char product that is stable in the outdoor environment and is more efficient as a feedstock for gasification or other processes than the original coal. Embodiments of the methods include pulverizing and pelletizing the coal, and pretreating the coal pellets to obtain a stable pellet of either dried coal or a stable pellet of chared coal (coal char). The pellets created by the described methods have undergone deoxygenation and carbonization improving their handling and storage properties and, in some cases, energy density. Pore structures within the pellets are stabilized physically and chemically so that the uptake of moisture into dry coal, that leads to internal heat generation, is greatly reduced. Chars are also, therefore, stable against transitions from a dry state to a wet state and less prone to self-ignition.

A layered representation of error propagation through quantum error detection circuits is received. The layered representation includes a plurality of line circuit layers that each represent a probability of local detection events in a quantum computer associated with one or more potential error processes in the execution of a quantum algorithm. During execution of the quantum algorithm, one or more syndrome measurements are received from quantum error detection circuits. The syndrome measurements are converted into detection events and written to an array that represents quantum error correction circuits that are grouped together at a sequence of steps in the quantum algorithm. Errors in the execution of the quantum algorithm are determined from the detection events in dependence upon the stored line circuit layers. Based on the determined errors, the syndrome measurements are corrected.

Abstract: The present invention provides methods and systems for digital processing of an input audio signal. Specifically, the present invention includes a high pass filter configured to filter the input audio signal to create a high pass signal. A first filter module then filters the high pass signal to create a first filtered signal. A first compressor modulates the first filtered signal to create a modulated signal. A second filter module then filters the modulated signal to create a second filtered signal. The second filtered signal is processed by a first processing module. A band splitter splits the processed signal into low band, mid band, and high band signals. The low band and high band signals are modulated by respective compressors. A second processing module further processes the modulated low band, mid band, and modulated high band signals to create an output signal.

Abstract: Systems and methods herein provide for improved handling of oversized email attachments. An example system can identify an oversized email attachment before an email is sent, by comparing the size of the attachment to a maximum file size at an email server. The user can then be notified that the attachment is over the allowable file size before sending the email. The system can also un-attach the oversized file, compress it using a suitable compression method, and reattach a compressed file. The compression can be done at the sender's request or automatically.
