Abstract: Embodiments of the present disclosure include techniques for securing the flow of configuration commands issued to network devices. When an authorized command source, such as an authorized user or program, issues a command, security data for the command is generated and associated with the command. The command and security data may flow across multiple software applications to the network device. The network device receiving the command may use the security data to verify that the command source is an authorized source and to validate that the command was unaltered.

Abstract: A fidgetable device that relays haptic feedback via magnetic coupling to hands and fingers, when an operator uses an outside magnet to drag an inside magnet over a rugged interior surface. This haptic experience is akin to walking a pet on a retractable leash. Thus the designation fidget walker. Said haptic device, with its acoustic side effects, is also widely applicable in a variety of fields including percussion instruments, underwater switches, magnetic locks, tabletop games, and even automated machineries.

Abstract: A volumetric instrument serving as a universal mixture maker. The instrument comprises fixed-shape solute cups that can be submerged in and fastened to solvent containers. The design allows a human operator to run an iterative method which finds a solution to a set of multivariate equations that would otherwise require situation-specific analytical calculations and the use of weighing scales. The iterative method can solve for one or more variables including solute volume, solvent volume, final mixture volume, and final solute concentration level. Cups and containers act as a mechanical calculator with a single parameter for the operator to manually adjust: how much of a solute cup to submerge in a solvent container. The mechanical calculator reduces mixture equations down to two markings for the operator to visually align: an output mixture marking on a cup, and a volumetric marking on a container.

Abstract: In some implementations, a method is provided. The method includes determining a physical topology of a network and monitoring network events based, at least in part, on control plane information received from one or more devices in the network. The method also includes monitoring the performance of each of a plurality of applications running on the network based, at least in part, on a set of application calls initiated by each application. When a drop in performance of an application is detected, the drop in performance is correlated with one or more of a plurality of detected network events to determine a cause of the drop in performance.

Abstract: Packets in a network may be dropped from time to time. Although network devices are able to provide counters specifying the number of dropped packets, these network devices are unable to provide additional context about the dropped packets. However, users of a network wish to know more about dropped packets; such as why the packets were dropped. Therefore, methods for capturing and storing the dropped packets are provided. This way, users can analyze the dropped packets to determine why these packets were dropped.

Abstract: A cold pack that can be fidgeted in a human hand. The cold pack encases a heat-transferring substance and provides a rigid portion suitable for being securely held by and readily fidgeted with fingers of said human hand. Heat-conducting grooves and heat-insulating surfaces are built into the rigid portion, with acute edges, jutting bumps, guard rails and other textures to provide grip. Fingertips alternate between holding the cold pack by said grooves and surfaces, thereby applying dynamic cold therapy to the same fingertips, rest of fingers, the hand, and other body parts requiring treatment for swelling, inflammation and trauma arising from friction, compression or minor burn injuries. Timely application of dynamic cold therapy can thus prevent formation of blisters in fingers and hands commonly seen in string players, musicians, sportspeople and workers caused by repetitive contacts with objects, and by unexpected contacts with hot surfaces.

Abstract: Chopstick buddies illustrated by various embodiments of the present disclosure are attachments to a chopstick. Chopstick buddies allow a human hand to avoid the awkward thumb pose required by the standard chopstick grip, while still being able to hold both chopsticks firmly as extensions of fingers. Chopstick buddies accomplish this without interfering with finger movements of the standard grip. As a result, users continue to enjoy benefits of the standard grip, despite not complying with the required and awkward thumb pose. These benefits include: the ability to extend tips of the chopsticks wide apart to embrace a food item, to manipulate chopsticks with dexterity, and to generate enough compression force to hold food items firmly between tips, with ease.

Abstract: Training chopsticks are designed to guide beginners and lifelong users alike to adopt a proper chopstick grip, allowing learners to extend chopstick tips wide apart. They allow learners to focus first on mastering the twirling of chopsticks between the closed posture to the wide-open posture, based on principles of the planetary gear train, without having to simultaneously learn to secure chopsticks using the required thumb pose. Such thumb pose can be mastered later as a second step. Furthermore, a variation of training chopsticks provides an elevated thumb rest to accommodate learners suffering from anatomical limitations. As a result, a learner can wield these training chopsticks to embrace large food items with ease, manipulate these large items with dexterity and finesse in the same way she can small items, and generate enough compression force to hold all items firmly between training chopsticks.

Abstract: Ergonomic chopsticks come with low-profile protrusions that are strategically placed. These protrusions generate tactile feedback on particular surfaces of a user's fingers, without hindering normal movements of fingers and chopsticks. They guide beginners and lifelong users alike to adopt a proper chopstick grip, allowing users to extend chopstick tips wide apart over an angle of 40 degrees. They help users twirl chopsticks from the closed posture to the wide-open posture, and back, based on principles of the planetary gear train, while ensuring that fingers and chopsticks stay within the standard grip form. As a result, a user can wield ergonomic chopsticks to embrace large food items with ease, manipulate these large items with dexterity and finesse in the same way she can small items, and generate enough compression force to hold all items firmly between ergonomic chopsticks.

Abstract: Systems and methods are described herein for configuring network layer connectivity between a network layer device and a host. A network controller receives, from the host, data link layer information about a network layer device and accordingly determines network layer information about the network layer device. The network controller configures the host and the network layer device to route traffic to each other over the network layer, by transmitting, to the host, the network layer information of the network layer device and by transmitting, to the network layer device, the network layer information of the host.
