Abstract: A method of operating a solid-state relay device includes receiving an input signal at an input of the solid-state relay device and coupling the input signal to transmit circuitry disposed on a transmit die. In response to receiving the input signal the transmit circuitry generates a corresponding time varying electrical voltage that is coupled from the transmit circuitry to a transmit coil and a receive coil is induced to generate an intermediate signal. A switch drive signal is generated which transitions a solid-state switch from an off state to an on state, wherein the switch drive signal corresponds to the input signal and wherein the drive signal is electrically isolated from the input signal.

Abstract: For a (stationary or mobile) robot within a monitored space, a safety subsystem generates a virtual representation of the robot using position and/or orientation data associated with the robot, detects an unexpected object within the monitored space using sensor data from a plurality of (external/internal) sensors, detects a virtual halt collision between the virtual robot and the virtual unexpected object based on a halt zone corresponding to the robot or the unexpected object, and generates an instruction to halt the normal operations of the robot. The (dynamic) virtual robot representation may include a robot arm movable with respect to the robot's base. The monitored space is generated by removing ignore zones corresponding to expected objects, including an ignore zone corresponding to the robot itself, from an initial (e.g., spherical) version of the monitored space. Regions having insufficient sensor coverage (i.e., IPZs) are treated as unexpected objects within the monitored space.

Abstract: A method of operating a signal isolation device includes receiving an input signal at an input of a transmit die and in response, generating a corresponding time varying electrical voltage at a transmitter output of the transmit die. The time varying electrical voltage is coupled to a transmit coil disposed within a receiver die. A receive coil is induced to generate an intermediate signal in response to the coupling of the time varying electrical voltage to the transmit coil, wherein the intermediate signal corresponds to the input signal. The intermediate signal is coupled to receiver circuitry disposed within the receiver die. Electromagnetic noise generated by the receive coil is shielded from the receiver circuitry via a shield positioned between the receive coil and the receiver circuitry.

Abstract: The embodiments described herein generally relate to a business-to-business or business-to-consumer software-as-a-service platform configured for monitoring and maintaining mattress health in a residential or commercial setting. The SaaS platform may be in operable communication with at least one sensor specifically associated with a mattress. Sensors may include temperature sensors, moisture sensors, gyroscopic sensors, soil sensors, and the like. A smart device, such as a smartphone, may also be in communication with the sensor via a computer program product executed by a processor on the smart device or on a server-based platform. The system may be configured to monitor and track mattress health overtime and provide notifications and instructions on when maintenance is required and performed correctly.

Abstract: A system has a virtual-world (VW) controller and a physical-world (PW) controller. The pairing of a PW element with a VW element establishes them as corresponding physical and virtual twins. The VW controller and/or the PW controller receives measurements from one or more sensors characterizing aspects of the physical world, the VW controller generates the virtual twin, and the VW controller and/or the PW controller generates commands for one or more actuators affecting aspects of the physical world. To coordinate the corresponding virtual and physical twins, (i) the VW controller controls the virtual twin based on the physical twin or (ii) the PW controller controls the physical twin based on the virtual twin. Depending on the operating mode, one of the VW and PW controllers is a master controller, and the other is a slave controller, where the virtual and physical twins are both controlled based on one of VW or PW forces.

Abstract: A method and an apparatus for generating a brain break alert is provided. The method includes receiving electroencephalographic (EEG) data of a patient engaged in a cognitive activity at a system server from a user device. The EEG data is captured by electrode of an EEG headset, where the electrode is in physical contact with the patient, and the EEG headset is communicably coupled to the user device. Brain energy used (BEU) by the patient is determined based on the EEG data, brain energy available (BEA) to the patient is determined as a function of the BEU and a predefined initial brain energy (BEI) of the patient, where the BEA is proportional to a difference between the BEI and the BEU, and the BEA satisfying a brain break alert threshold is determined, upon which an instruction to generate a brain break alert (BBA) is sent to the user device.

Abstract: Methods and apparatus for subtractively fabricating three-dimensional structures relative to a surface of a substrate and for additively depositing metal and dopant atoms onto the surface and for diffusing them into the bulk. A chemical solution is applied to the surface of the semiconductor substrate, and a spatial pattern of electron-hole pairs is generated by projecting a spatial pattern of illumination characterized by a specified intensity, wavelength and duration at each pixel of a plurality of pixels on the surface. Charge carriers are driven away from the surface of the semiconductor on a timescale short compared to the carrier recombination lifetime. Such methods are applied to creating a spatially varying doping profile in the semiconductor substrate, a photonic integrated circuit and an integrated photonic microfluidic circuit.
