Abstract: A footwear construction including a sole assembly, which can include a midsole including a midsole support wall forming a compartment and a compression molded core constructed from thermoplastic polyester elastomer (TPEE) disposed in the compartment and shielded from abrasion in the environment of the footwear in use via the midsole support wall. The core can be formed by compressing a foam core to increase its density, for example, from a first density between 0.05 g/cm3 and 0.08 g/cm3, inclusive, to a second density between about 0.09 g/cm3 and 0.12 g/cm3, inclusive. Such compression molding and the attendant density increase of the TPEE core can increase energy efficiency to at least 95% energy efficiency, when the midsole is installed in footwear. A related method of manufacture is provided.

Abstract: An afocal sensor assembly detects a light beam with an aberrated wavefront. The afocal sensor assembly is configured to provide sorted four-dimensional (4D) light field information regarding the light beam, for example, via one or more plenoptic images. Based on the 4D light field information, a lossy reconstruction of an aberrated wavefront for one or more actuators of an adaptive optics (AO) device is performed. The AO device can be controlled based on the lossy reconstruction to correct the wavefront of the light beam. In some embodiments, the aberrated wavefront is due to passage of the light beam through atmospheric turbulence, and the lossy reconstruction and correction using the AO device is performed in less than 1.0 ms. The lossy reconstruction of the aberrated wavefront can have a phase accuracy in a range of ?/2 to ?/30.

Abstract: A robotic work cell uses an object separating mechanism to disperse bulk objects into a 2D arrangement on a horizontal surface and uses a vision system to generate pick-up (positional) data and rotational orientation data for each sequentially selected target object of the 2D arrangement. A pick-and-place robot mechanism uses the positional data to pick-up each target object and uses the rotational orientation data to reorientate the target object during transfer to a designated hand-off location. A carousel-type robotic end-tool disposed on a 4-axis object-processing robot mechanism rotates a gripper mechanism around a vertical axis to move the target object from the hand-off location to a designated processing location, where an associated processing device performs a desired process (e.g., label application) on the target object. In one embodiment the gripper mechanism is selectively rotatable around a horizontal axis to facilitate processing on opposing surfaces of the target object.

Abstract: An Inventory Management and Delivery System (IMDS system) manages product items within a climate-controlled enclosure (e.g., beverage case) in an automated manner using a product loading (ingestion) subsystem to convey product items into the enclosure's climate-controlled environment and utilizes two gantry robots and an articulated robot to perform all backstocking/storage and delivery/restocking operations. Product items are ingested on standardized crates to simplify backstocking/retrieval of various product types from an array of storage locations using the first (backstocking) gantry robot. During restocking operations, the required crates are retrieved from storage and individual items are extracted and by the articulated robot and transferred to the second (delivery) gantry robot. The second gantry robot utilizes a simplified channel-type delivery mechanism to deliver each product item to its associated display shelf location.

Abstract: A work cell and method for automatically separating objects disposed in 3D clusters includes dispensing the objects onto a horizontal conveying surface to form a 2D array, reforming the 2D array into a 1D stream in which the objects move in single-file in a predefined moving direction, utilizing a vision-based or other stationary sensing system to identify a selected target object in the 1D stream as the target object passes through an image capture (sensing) region, calculating trajectory data defining the target object's time-based position in the 1D stream, and then utilizing the trajectory data to control a robot arm or other object removal mechanism such that only the selected object is forcibly removed (e.g., swiped or picked-up) from the horizontal conveying surface. A continuous-loop-type conveying mechanism includes two parallel conveyor-belt-type conveying structures and associated belt-switching structures. An AI-powered vision system identifies new object shapes during preliminary learning phases.

Abstract: A human-like tactile perception apparatus for providing enhanced tactile information (feedback data) from an end-effector/gripper to the control circuit of an arm-type robotic system. The apparatus's base structure is attached to the gripper's finger and includes a flat/planar support plate that presses a pressure sensor array against a target object during operable interactions. The pressure sensor array generates pressure sensor data that indicates portions of the array contacted by surface features of the target object. A sensor data processing circuit generates tactile information in response to the pressure sensor data, and then transmits the tactile information to the robotic system's control circuit. An optional mezzanine connector extends through an opening in the support plate to pass pressure sensor data to the processing circuit. An encapsulating layer covers the pressure sensor array and transmits pressure waves generated by slipping objects to enhance the tactile information.

Abstract: An automated food production work cell includes a robotic system that utilizes a food-grade robotic gripper to transfer individual food items. The robotic gripper is constructed using food-grade materials and includes finger structures that are linearly movably connected by linear bearings to parallel guide rods and are independently driven by a non-contact actuating system to grasp targeted food items disposed on a first work surface, to hold the targeted food items while the robotic system moves the gripper to a second work surface, and to release the targeted food items onto the second work surface. Encoding and external sensing systems facilitate fully automated food transfer processes. Optional sensor arrays are disposed on tip portions of the finger structures to provide feedback data (e.g., grasping force/pressure). Two or more pairs of independently controlled finger structures are provided to facilitate the transfer of multiple food items during each transfer process.

Abstract: A robotic gripper (end effector) for an arm-type robotic system includes a hierarchical sensor architecture that utilizes a central data processing circuit to generate rich sensory tactile data in response to pressure, temperature, vibration and/or proximity sensor data generated by finger-mounted sensor groups in response to interactions between the robotic gripper and a target object during robotic system operations. The rich sensory tactile data is used to generate feedback signals that directly control finger actuators and/or tactile information that is supplied to the robotic system's control circuit. Sensor data processing circuits are configured to receive single-sensor data signals in parallel from the sensor groups, and to transmit corresponding finger-level sensor data signal on a serial bus/signal line to the central data processing circuit.

Abstract: A neuromodulator includes one or more coil sets. Each of the coil sets has three coils aligned to produce magnetic and electric fields in three different directions. A plurality of conductors couple the coils of the one or more coil sets to one or more input signals such that each of the coils is independently activated via an individually selectable current applied through the conductors. The individual activation creates a resultant field that is a combination of the magnetic and electric fields in three different directions for each of the coil sets.

Abstract: A flex-rigid sensor apparatus for providing sensor data from sensors disposed on an end-effector/gripper to the control circuit of an arm-type robotic system. The apparatus includes piezo-type pressure sensors sandwiched between lower and upper PCB stack-up structures respectively fabricated using rigid PCB (e.g., FR-4) and flexible PCB (e.g., polyimide) manufacturing processes.

Abstract: A multimodal sensing architecture utilizes an array of single sensor or multi-sensor groups (superpixels) to facilitate advanced object-manipulation and recognition tasks performed by mechanical end effectors in robotic systems. The single-sensors/superpixels are spatially arrayed over contact surfaces of the end effector fingers and include, e.g., pressure sensors and vibration sensors that facilitate the simultaneous detection of both static and dynamic events occurring on the end effector, and optionally include proximity sensors and/or temperature sensors. A readout circuit receives the sensor data from the superpixels and transmits the sensor data onto a shared sensor data bus.

Abstract: A device includes at least one stress-engineered portion and at least one second portion. The stress-engineered portion includes at least one tensile stress layer having a residual tensile stress and at least one compressive stress layer having a residual compressive stress. The tensile stress layer and the compressive stress layer are mechanically coupled such that the at least one tensile stress layer and the at least one compressive stress layer are self-equilibrating. The stress-engineered portion is configured to fracture due to propagating cracks generated in response to energy applied to the stress-engineered portion. Fracture of the stress-engineered portion changes functionality of the device from a first function to a second function, different from the first function.
