  • Publication number: 20210139332
    Abstract: Disclosed herein are methods of synthesizing a hybrid nanomaterial comprising 3D out-of-plane single- to few-layer fuzzy graphene on a scaffold, such as a Si nanowire mesh through a plasma-enhanced chemical vapor deposition process. By varying graphene growth conditions (CH4 partial pressure and process time), the size, density, and electrical properties of the hybrid nanomaterial can be controlled. Porous nanowire-templated 3D graphene hybrid nanomaterials exhibit high electrical conductivity and also demonstrate exceptional electrochemical functionality.

  • Patent number: 10998835
    Abstract: An electrostatic clutch is described comprising a plurality of micron-scale thickness electrodes, adjacent electrodes being separated by a thin film of dielectric material. A power source and controller apply a voltage across two electrodes, causing an electrostatic force to develop. When engaged, a force can be transferred through the clutch. A tensioning device maintains the alignment of the clutch when the electrodes are disengaged, but permits movement in at least one direction. In some embodiments, multiple clutches are connected to an output to provide variable force control and a broad range of torque input and output values. Moreover, the clutch can be used as an energy-recycling actuator that captures mechanical energy from negative work movements, and returns energy during positive work movements.

  • Publication number: 20210109593
    Abstract: A system and method for detecting when a user contacts one arm to an opposing arm. The system comprises an emitter worn by the user on one arm and a receiver located on an opposing arm, on the user's head, or on a different part of the user's body. Contact, or touch, is indicated by comparing the value of an electrical signal flowing along a path establish, in part, through the user's skin to a threshold. When touch is initiated, multiple electrical paths are created, including one that generates airborne signal emanating from the user's body.

  • Patent number: 10946098
    Abstract: Provided herein is a two-component photosensitizer, which demonstrated robust and selective killing effects for transfected HEK cells and affibody targeted A431 cancer cells when exposed to near infrared light excitation. Free MG2I is a pure and stable fluorogen; it is easy to synthesize and modify, and has no toxicity to cells. Unlike conventional photosensitizers, the dye and FAP itself has no photosensitizing effect until they are bound. Also unlike other activation methods, the activation step is achieved by adding the fluorogen, not the presence of the targeted molecule, requiring an ‘active’ activation instead of a ‘passive’ activation. This method offers the ability to locally switch-on and selective generation of singlet oxygen at the target site and can be used for a wide variety of molecular targets.

  • Patent number: 10945339
    Abstract: The disclosure describes a soft-matter electronic device having micron-scale features, and methods to fabricate the electronic device. In some embodiments, the device comprises an elastomer mold having microchannels, which are filled with an eutectic alloy to create an electrically conductive element. The microchannels are sealed with a polymer to prevent the alloy from escaping the microchannels. In some embodiments, the alloy is drawn into the microchannels using a micro-transfer printing technique. Additionally, the molds can be created using soft-lithography or other fabrication techniques. The method described herein allows creation of micron-scale circuit features with a line width and spacing that is an order-of-magnitude smaller than those previously demonstrated.

  • Patent number: 10940863
    Abstract: Systems and methods are provided that employ spatial and temporal attention-based deep reinforcement learning of hierarchical lane-change policies for controlling an autonomous vehicle. An actor-critic network architecture includes an actor network that process image data received from an environment to learn the lane-change policies as a set of hierarchical actions, and a critic network that evaluates the lane-change policies to calculate loss and gradients to predict an action-value function (Q) that is used to drive learning and update parameters of the lane-change policies. The actor-critic network architecture implements a spatial attention module to select relevant regions in the image data that are of importance, and a temporal attention module to learn temporal attention weights to be applied to past frames of image data to indicate relative importance in deciding which lane-change policy to select.

  • Patent number: 10942550
    Abstract: The present invention includes provides secure, instant, and anonymous connections between two devices. The invention pairs a “cap” device with a capacitive touchscreen to a “cam” device with a camera sensor. For example, typical smartphones and tablets can be paired with each other, and these devices can be paired to even larger touchscreens, such as smart whiteboards and touchscreen monitors. The invention uses the cap device's touchscreen to detect and track the cam device, and displays color-modulated pairing data directly underneath the camera once the camera is touching the screen. The pairing data is used as configuration data for a bidirectional link, such as an ad-hoc WiFi or Bluetooth link. These links are established without requiring user configuration. As such, the present invention provides a unidirectional communication mechanism from the touchscreen to the camera, which is used to bootstrap a full bidirectional, high-speed link.

  • Publication number: 20210061278
    Abstract: A method for controlling automated driving operations of a vehicle includes determining vehicle origin and destination data, and generating a graphical representation of a road network with multiple candidate routes between the vehicle's origin and destination. Road-level data, including speed, turn angle, and/or gradient data, is received for each candidate route, and respective total energy uses are estimated for the vehicle to traverse across the candidate routes. Multiple candidate driving strategies, each having respective speed and acceleration profiles, are determined for the candidate route with the lowest estimated total energy use. An optimal candidate driving strategy is selected through a cost evaluation of the associated speed and acceleration profiles and forward movement simulations of the vehicle over a prediction horizon.
