Title: Methods and apparatus for use in predicting non-stationary time-series data
Inventor: JOSEPH TOWNSEND
IPC: G06Q40/06
Filed: 2016-04-29
Abstract: A computer-implemented data prediction method carries out a prediction cycle in which a neural network outputs a predicted value of non-stationary time-series data at a next time step, where values of the data are known for and up to the current time step. In each cycle the inputs for a neural network are selected dynamically by performing an input selection process. This process comprises determining, for a set of candidate indicators, the causality between values of the data and values of each indicator using a causality measure, such as Granger causality, and selecting a subset of indicators which yield the highest causal correlation with the data, to be the inputs for the neural network at that time-step. The primary application disclosed is predicting next day direction of a stock price.

Title: Soot load estimation during idle or low load
Inventor: TONY J HALL
IPC: F02D41/02
Filed: 2016-11-10
Abstract: A system includes an engine, an aftertreatment system with a particulate filter, which may be a DPF, and a controller configured to compare a time value since a last delta pressure soot load estimate (DPSLE) process to a predetermined time threshold 412. If the time value is greater than or equal to the predetermined time threshold, the controller decreases a flow threshold value to a lower flow threshold value 414. If the flow amount is greater than or equal to the lower flow threshold value 422, then the controller activates a DPSLE process 426. A combined soot load estimate is then calculated using a DPSLE from the DPSLE process. In this way, the DPSLE is updated during idle or low speed engine conditions. The controller may also increase a flow amount in the aftertreatment system if the time value is greater than or equal to the threshold. Also claimed is a method for increasing the exhaust flow to update a DPSLE, and an apparatus comprising a controller including a mass based soot load rate circuit, a DPSLE circuit, a combined soot load estimate circuit, and a low flow soot operations circuit.

Title: Prevention of switching discontinuity in a hybrid switched mode amplifier
Inventor: ERIC J KING
IPC: H03F3/217
Filed: 2017-03-03
Abstract: A hybrid switched mode amplifier (20 fig 3) is described, capable of driving audio transducers, comprising a signal splitter (22), a first control loop (buck/boost converter 26 figure 4) acting on signal segment VIN_1 (figures 3,6) of input Vin and a second control loop 28 acting on signal segments VPRE, VIN_2 and Vin. The invention relates to the second control loop 28 which comprises first and second signal processing paths (VPC-to-Vout+, Vin-to-Vout-) providing a differential output load voltage Vout (Vout+/Vout-). The system further controls the switches 54,56,58,59/64,66,68,70 of a switching full-bridge to commutate polarity of a capacitor (52/62) with respect to first and second processing paths based on a commutation condition, e.g when Vout is non-zero. The second processing path loop compares Vout and Vin to provide Vout- via a linear amplifier 60. In addition a feedforward compensation VIN_2, VPRE is applied which bypasses second processing path loop filter 44 and prevents loop-filter compensating discontinuities caused by commutating capacitor (fig 7). The second processing path may further comprise a low pass filter comprising a capacitor 52 and resistor 48 coupled to the output of the loop filter, such that the feedforward compensation VIN_2, VPRE is inserted between the output of the loop filter 44 and the low-pass filter 48,52,54-58. The system enables integration of a consumer audio amplifier into mobile-devices, without incurring large filter components (capacitors). It utilises efficient switch-mode audio amplifiers in parallel with linear audio amplifiers. The low-pass-filter acts as a high-pass filter for the first processing path and passes high frequency converter ripple signals to both terminals of the differential output, eliminating costly filtering.

Abstract: A robot operates in an unmonitored or monitored mode. At least one operation parameter is communicated to a third party. When the robot receives a signal indicating the third part is receiving the parameter data operates the robot in a monitored mode. In the absence to receive the signal the robot operates in an unmonitored mode. A robot may be allowed to perform certain operations if monitored or prevented from such operations if unmonitored. If authorized, a robot may be able to perform certain operations unmonitored; however, the third party may report the authorized exception. Should the robot be unmonitored, and absent unauthorized exception, the robot performs only those operations approved for unmonitored mode. Otherwise, the robot is enabled to perform tasks approved for monitored and unmonitored mode. The third party may report the monitoring, lack of monitoring, and compliance with a monitoring program accordingly.

Title: Environmental map generation from a digital image
Inventor: XUE BAI
IPC: G06T15/50
Filed: 2017-08-24
Abstract: Environmental map generation techniques and systems are described. A digital image is scaled to achieve a target aspect ratio using a content aware scaling technique. A canvas is generated that is dimensionally larger than the scaled digital image and the scaled digital image is inserted within the canvas thereby resulting in an unfilled portion of the canvas. An initially filled canvas is then generated by filling the unfilled portion using a content aware fill technique e.g. seam carving based on the inserted digital image. A plurality of polar coordinate canvases is formed by transforming original coordinates of the canvas into polar coordinates. The unfilled portions of the polar coordinate canvases are filled using a content-aware fill technique that is initialized based on the initially filled canvas. An environmental map of the digital image is generated by combining a plurality of original coordinate canvas portions formed from the polar coordinate canvases.

Title: System and method for providing an indication of driving performance
Inventor: SESHADRI ARJUN KRISHNA
IPC: G07C5/08
Filed: 2018-12-03
Abstract: A method of, and system for, providing an indication of driving performance involves obtaining a forward acceleration and speed of a vehicle. A forward acceleration threshold value is determined based on the obtained speed of the vehicle. For any vehicle speed within a range of vehicle speeds, the acceleration threshold value is defined by a function based on the determined speed of the vehicle. The acceleration threshold value varies continually with vehicle speed over the range of vehicle speeds, such as in a curve with the threshold value decreasing with increasing vehicle speed. The obtained forward acceleration of the vehicle is compared with the determined acceleration threshold value. An indication of an excessive forward acceleration driving event is generated when the obtained forward acceleration exceeds the determined acceleration threshold value. The function can have upper and lower speed limits having a constant acceleration threshold above and below the speed limits. A mass of the vehicle can also be estimated based upon the obtained the forward acceleration and the speed and, potentially, an obtained fuel consumption when the acceleration is above the threshold. The variable acceleration threshold may provide a more appropriate measure of harsh driving events than fixed thresholds.
