Abstract: The design, creation, use, and execution of command line parsers based on subcommand classes instead of boilerplate code is described. Commands and subcommands have corresponding class definitions, which upon instantiation based on command line content will provide and execute code to perform the command. Subcommand dispatching may be accomplished using delegates, using an interface implementation, or otherwise. Class attributes may define help text, argument aliases, and other metadata. Subcommand types may be passed as generic arguments, as objects, or otherwise. Arguments may be made optional or be required by providing or omitting class constructor parameter default values. By using classes to implement subcommands and avoiding reliance on large error-prone if or switch statements, parser development is made easier and more efficient.

Abstract: Techniques for searching a character string involve: determining a first set of documents including a first token in the character string, and a second set of documents including a second token in the character string; and generating a third set of documents based on the first and second sets of documents, in the third set of documents: i) a document being included in the first and second sets of documents, and ii) a distance between the first and second tokens in the document being equal to a distance between the first and second tokens in the character string.

Abstract: A method begins with a server in a data communication system establishing an initial validity of an exchange item that includes data regarding a quantifiable value, a serial number, and issuance information, where the initial validity authenticates the exchange item and the data. The method continues with the server executing a secure custody protocol to establish that a first computing device has secure custody of the exchange item and to maintain validity of the exchange item. The method continues with the server transferring the secure custody of the exchange item from the first computing device to the server or to a second computing device. When the exchange item is in the secure custody of the server the method continues with the server modifying the data of the exchange item to produce a modified exchange item and transferring secure custody of the modified exchange item to the first computing device.

Abstract: Identifying user input data on a mobile user device may provide a way to predict the types of questions and actions a user will take and offer information contemporaneously with such actions. One example method of operation includes identifying an active application programming interface (API) of a presently operating application executing on the user device, and identifying input data populating the application. Then, storing and processing the input data to identify a topic of interest and retrieving relevant content that is associated with the topic of interest, and creating a recommendation message based on the relevant content.

Abstract: A shock absorber includes a bottom rim, a top wall comprising a raised central portion and a top rim, a side wall extending between the top and bottom rims, and a corrugation surrounding a periphery of the raised central portion that (i) connects the raised central portion to the top rim, (ii) descends to a depth below half a height of the side wall, and (iii) is separated by a distance from a surface. Impact forces imparted on the shock absorber are attenuated by a first amount in a first stage by resistive yielding of the side wall; by a second amount in a second stage by depression of the central portion and resistive yielding of the corrugation associated therewith; and by a third amount in a third stage by resistive yielding of the corrugation in response to a force applied to the top rim upon contact with the surface.

Abstract: A self-cleaning window blind includes a thin layer of photocatalytic material on at least one surface of the slats. The window blind includes an ultraviolet light source which directs ultraviolet light onto the photocatalytic material. Consequently, the window blind is not dependent on available sunlight. The ultraviolet light source is located in either the headrail or the bottom rail of the window blinds. Upon exposure to ultraviolet light, organic material on the slats which may include dust, grease, or microorganisms, is converted to carbon dioxide and water. One or both of the horizontal edges of the slats may include a lip which collects water formed by the photocatalytic reaction. In some embodiments, the slats are slightly convex. This shape may inhibit water from collecting in droplets on the slat and help direct the water towards the lip. Consequently, water spots are not created on the slats.

The cam is coupled to the torsion spring about a shared rotational axis such that the cam directs elastic energy to and from the torsion spring and the cable transforms rotational force into linear motion, with little rotational inertia, and the addition of angular acceleration.

Abstract: The arithmetic educational tool utilizes a container having a main chamber and two extended chambers from the main chamber to visually demonstrate addition and subtraction. Objects placed with the container will move from the main chamber into the extended chambers when the container is tilted and thereby break the number objects in the main chamber into parts. The container is bifurcated, having the two extended chambers branching off of from the main chamber and thereby causes a random splitting of the number of objects into each of the extended chamber. Conversely, objects placed in each of the extended chambers can be added when the chamber is tilted to cause the object to move from the extended chambers into the main chamber. One or more of the chambers may have an obscuring feature, such as a color or slidably cover, that enables obscuring the number of objects therein.

Abstract: Methods, systems, and computer program products are described herein for automatic collision avoidance and/or bodily injury mitigation. For example, a vehicle determines the optimal action(s) to take to avoid a collision or reduce the bodily injury of occupant(s) of the vehicle in the event that the vehicle determines that the collision is unavoidable. The vehicle performs action(s) that reduce the change of momentum experienced by occupant(s) thereof as a result of the collision. The actions are based on various characteristics of the vehicles that are to be involved in the collision. Such actions may comprise accelerating into and causing a collision with vehicle(s) in front of the vehicle at or around the same time at which a further vehicle rear-ends the vehicle. The system processes several scenarios in real-time (taking into changes of velocity of the vehicles involved) to determine the scenario that best mitigates the change of momentum.
