Abstract: A robotic system is disclosed. In various embodiments, sensor data is received. A plan is determined, based at least in part on the received sensor data, to use a robotic arm to build a stack of items comprising a plurality of items, the plan including with respect to at least a subset of the items a plan to move the item to an initial position on the stack and then reposition and use the robotic arm to pack the item more snugly against an adjacent surface. The plan is implemented at least in part by sending one or more commands to a robotic arm.

Abstract: A robotic system comprising a plurality of autonomously acting robots configured to cooperate with each other to perform an operation is disclosed. In various embodiments, a system as disclosed herein includes a first robot configured to determine a plurality of items required to be obtained to fulfill a first order; and a second robot configured to receive an indication to retrieve and provide to the first robot a first item included in the plurality of items; and to plan and perform a first subtask to retrieve the first item and provide the first item to the first robot.

Abstract: A decision-feedback equalizer (DFE) includes a combining circuit and a feedback filter. The combining circuit combines an input signal and at least one feedback signal to generate an equalized signal. The feedback filter generates the at least one feedback signal according to the equalized signal, and includes a controllable delay circuit. The controllable delay circuit receives an output signal that is derived from the equalized signal, and applies at least one delay amount to generate at least one delay signal, wherein the at least one feedback signal is derived from the at least one delay signal.

Abstract: Systems and methods thereof for image correction are provided in an exemplary method, an image is received and pixels therein are read. A frequency value is calculated for each of the color scale values, representing how many pixels correspond to each of the color scale values. A color-scale threshold is acquired by limiting summation of frequency values from the brightest end to the color-scale threshold being a minimum value exceeding or equaling a ratio of pixels. Lower/upper limits are acquired by respectively adding/subtracting a range value to/from the color-scale threshold. A weighted value is acquired for the pixels with pixel values between the lower color-scale limit and the upper color-scale limit. The updated image is generated by replacing pixel values between the lower limit and upper limit with the weighted value.

Abstract: A method of determining color composition of an image includes calculating an intensity value and a saturation value for each pixel of the image, comparing the calculated intensity and saturation values for each pixel with first and second predetermined threshold values, respectively, and labeling pixels with calculated intensity values above the first predetermined threshold value and calculated saturation values above the second predetermined threshold value as color pixels. Next, a mask is applied to the image and the number of color pixels selected by the mask is counted. If the number of color pixels selected by the mask is greater than or equal to a predetermined density value, the image is determined to be a color image.

Abstract: High performance MEMS thin film electret microphones, components and methods for making the same are disclosed. The microphones generally include a transducer diaphragm including an IC-compatible membrane support structure, a membrane layer formed on the membrane support structure, and a first electrode; a transducer back plate having a second electrode; and an electret layer formed on at least one of the transducer diaphragm or the transducer back plate. The transducer diaphragm and transducer back plate are fabricated using micromachining techniques and are generally compatible with microelectronics. The microphones generally have high open-circuit sensitivities, low noise levels, and low total harmonic distortion.
