Abstract: The present disclosure relates to methods and compositions of removing a histological stain from a histologically stained sample. The method may include contacting the sample with an acidic agent, contacting the sample with a reducing agent, thereby removing the histological stain from the histologically stained sample.

Abstract: Systems and methods for fleet inspection and maintenance using a robot are provided. The robot may detect a maintenance issue of a vehicle of a fleet of vehicles via one or more sensors, generate a navigation route to a position proximal to the maintenance issue of the vehicle, traverse along the navigation route to the position, and execute a maintenance to rectify the maintenance issue of the vehicle. The robot may include a mobile base removably coupled to a modular platform for performing a maintenance task.

Abstract: Systems and methods for administering a hazard condition warning during a package delivery operation are provided. The system includes one or more sensors, e.g., radar sensors or cameras, configured to detect a hazard condition in a vicinity of a delivery vehicle and to generate data indicative of the hazard condition. The system further includes an operator sensor configured to detect a location of an operator relative to the delivery vehicle and one or more indicators, e.g., lights, a mobile application installed on a mobile phone, or an HMI of the vehicle, configured to generate an alert corresponding to the hazard condition. A processor of the system may determine whether the hazard condition is present based on the data indicative of the hazard condition, and cause, based on a presence of the hazard condition and the detected location of the operator, the one or more indicators to generate the alert.

Abstract: A decision feedback equalizer is configured to equalize an input signal to generate a recovered output signal. Linear feed-forward filter circuitry is configured to provide a linearly filtered output signal based on the input signal. Composite trellis decoder circuitry configured to process a combined signal that is based on a combination of at least the linearly feed-forward filtered output signal and on output of linear or non-linear feedback filter circuitry, in accordance with state metrics generated by processing a composite trellis diagram relative to the combined signal, to provide a trellis-decoded output signal as input to the linear or non-linear feedback filter circuitry.

Abstract: Symbol timing is performed by providing a histogram of samples of a signal for a predetermined number of symbol times. An average, weighted average, or other method is applied to determine an average timing for a max eye opening for each symbol time. The average max eye opening timing is applied to an edge detection of a currently received signal to determine timing of a sample that is most likely to occur closest to the max eye opening for the current symbol. The invention may also be practiced based on a center timing of each symbol.

Abstract: Method and system for efficiently and quickly forming a sequence of convolution values from an over-sampled digital signal sequence. Convolution value differences are computable from a set of digital signal values that is smaller than the original set of signal values by a factor of R, the over-sampling rate. The number of adders and the associated time delay for computation of the convolution differences are reduced by at least a factor R and by at least a factor approximately proportional to log2(R), respectively, as compared to conventional computation of a convolution value. This approach is used to estimate a time value for which the convolution attains a largest magnitude or value.
