Abstract: Disclosed techniques for improving computational efficiency can be applied to synthesis and analysis in digital signal processing. A base discrete-time Orthogonal Frequency Division Multiplexing (OFDM) signal is generated by performing an inverse discrete Fourier transform (IDFT) on a set of data symbols. The set of data symbols is multiplied with a sparse update weight matrix to produce an update signal, and an IDFT is performed on the update signal to generate a discrete-time update signal. The discrete-time update signal is summed with the base discrete-time OFDM signal to produce an updated discrete-time OFDM signal.

Abstract: An error detection and flow rate monitoring system of a liquid fertilizer distribution system of an agricultural implement that can provide feedback to identify compromised flow states in the system and corresponding locations of potential blockage or component failure. The system may include pressure sensors that may be evaluated in pairs or otherwise analyzed comparatively to determine flow rate or other characteristics through nozzle assemblies. The pressure sensors may be mounted in the wet boom between the rows. A control system compares the pressure values before and after each row to determine the pressure drop across its nozzle assembly and may further use the pressure drop values to determine flow or application rates and corresponding errors in the pressure drop, flow rate, and application rate compared to their acceptable values and may provide feedback to identify a specific location(s) of potential blockage or flow-control component failure.

Abstract: A system operates to bypass one or more exhaust purifying devices during deceleration fuel cut-off (DFCO) events in order to avoid hydrocarbon purging. The system includes an internal combustion engine and exhaust purifying system including a first purifying device and a second purifying device. An exhaust gas sensor monitors an exhaust gas feedstream. A diverter valve is disposed to manage the exhaust gas feedstream and fluidly coupled to an exhaust diversion pipe. A controller detects operation of the engine in a DFCO state and monitors the exhaust gas feedstream via the exhaust sensor. The diverter valve is controlled to divert the exhaust gas feedstream away from at least one of the first and second purifying devices during the DFCO event when the exhaust gas feedstream has an air/fuel ratio that is greater than a threshold air/fuel ratio.

Abstract: A system for capturing and destroying hair and waste within a shower drain includes a basket placed in the drain which holds a rod including an enzyme blend. The basket captures hair or waste that is washed down shower drains. The enzyme blend neutralizes the hair or waste. The result is a clear drain and clear plumbing, with minimal manual labor. The basket does not require removal because the hair and waste are neutralized before a clog can develop. The enzyme blend is safer for both users and the plumbing systems treated than conventional drain cleaning chemicals.
