Abstract: The disclosed system produces synthetic signals for testing machine-learning systems. During operation, the system generates a set of N composite sinusoidal signals, wherein each of the N composite sinusoidal signals is a combination of multiple constituent sinusoidal signals with different periodicities. Next, the system adds time-varying random noise values to each of the N composite sinusoidal signals, wherein a standard deviation of the time-varying random noise values varies over successive time periods. The system also multiplies each of the N composite sinusoidal signals by time-varying amplitude values, wherein the time-varying amplitude values vary over successive time periods. Finally, the system adds time-varying mean values to each of the N composite sinusoidal signals, wherein the time-varying mean values vary over successive time periods.

Abstract: A robust, reusable, and modular shipping container for protecting large, fragile, odd-shaped, or high-value cargo from damage during shipment. Such cargo may include telecommunications cabinets, appliances, and furniture. The shipping container minimizes the possibility of shipping damage due to improper handling, tip-overs, lateral collisions, or vibration. Such a shipping container may include a pallet base, a lower frame section, an upper frame section, and a top cover, the assembly of the pallet base, lower frame section, upper frame section, and top cover defining a protective outer cage having an interior in which the cargo is disposed.

Abstract: Systems and methods of supporting communications over a common network connection in a master-slave field bus network with a first type of packet formatted with a time-sensitive protocol and a second type of packet formatted with a non-time-sensitive protocol are provided. The slave devices are configured with filters to prevent the first type of packet from reaching a configurator and the second type from reaching a master device. The slave devices are also configured with arbitration logic so that the packets formatted with the time-sensitive protocol are provided with a priority over the packets formatted with the non-time-sensitive protocol.

Abstract: A method and system for adding a node into a network operating in a cyclic state after one or more nodes have been previously removed without interrupting the synchronous traffic of the remaining nodes on the network is provided. The method includes discovering an added node by sending data to the added node in a downstream timeslot previously assigned to a removed node, the data having a delay value for scheduling a response from the added node to coincide with an upstream timeslot previously assigned to the removed node, thereby avoiding collisions with the synchronous traffic on the network; receiving the response from the added node; configuring the added node in accordance with an original configuration of the removed node; and commencing cyclic operation of the added node.

Abstract: The instant disclosure relates to methods of providing a composition containing estrogen or a biological equivalent thereof to a subject in need of such treatment, wherein a therapeutically effective amount of the estrogen or biological equivalent thereof is administered to the subject via inhalation of an electrohydrodynamic spray.

Abstract: An improved system, method, and computer-readable instructions for scheduling, transporting, and receiving inbound packets efficiently in networks with cyclic packet scheduling is provided. The method provides for scheduling upstream packet transmission slots for each node in the network so that the spacing between the packet transmission slots is reduced; for each node in the network, if there is a locally originated packet of the node to be transmitted upstream, selectively activating a forwarding buffer to receive and temporarily store a packet received from a neighboring downstream node during upstream transmission of a locally originated packet of the node; and upon completion of the upstream transmission of the locally originated packet, transmitting upstream the packet stored in the forwarding buffer.

Abstract: Methods and devices for dispensing an aerosolized liquids that generate an electric field proximate an outlet of a liquid supplier to cause liquid issuing from the outlet to be aerosolized for dispensing, and regulating an electrical characteristic, such as voltage, for generating the electric field based on a detected electrical characteristic, e.g., current drawn, of the electric field and/or based on an environmental sensor, to compensate, for example, for adverse effects of relative humidity in the aerosolization process. Such methods and devices are suitable for use as, for example, an inhaler for dispensing therapeutic liquids to a patient's lungs, spraying paint, crops or other liquids over a surface area.

Abstract: A motion control system and method that includes a central controller configured to generate first and second demand control signals to be used to define actuation motion of respective first and second actuators. The central controller is in communication with first and second nodes by way of a data network, each node including at least a respective actuator configured to implement at an actuator time a motion or force-related effort based upon the respective demand control signal. Each node also includes a memory configured to store at least one respective propagation delay parameter related to a signal propagation delay between the central controller and the node. A timing mechanism establishes timing at each node based on the respective propagation delay parameter so that the actuator time at the nodes occurs simultaneously. Strictly cyclic and/or full-duplex high-speed communication can be supported. The network can be wired in a ring or as a tree and with twisted pair cabling or fiber.

Abstract: A bath tub cushion for lining one end surface and a portion of a bottom surface of a bath tub includes a back portion having a number of fluid impermeable chambers formed therein. A fluid communication device is disposed in fluid communication with an interior portion of the chambers for inflating and deflating them as necessary. An anti-slip mechanism is disposed on a back surface of the back portion which engages an end of such bath tub to prevent movement during use. A bottom portion extends toward an opposed end of such tub and is connected to a bottom edge of a front portion of such back portion for supporting a person's hips during bathing. There is an additional anti-slip mechanism disposed on a bottom surface of the bottom portion which engages bottom surface of such bath tub for preventing movement of the bottom portion during use.
