  • Patent number: 10802980
    Abstract: A computing device includes a volatile memory that includes a first cache, a non-volatile storage that includes a second cache, and a cache service. The cache service, responsive to a cache miss, retrieves that asset and writes that asset to the first cache and not the second cache. The cache service reads the asset from the first cache responsive to requests for the asset until the asset is evicted from the first cache or until the asset is promoted to the second cache. The cache service promotes the asset to the second cache upon determining that a set of one or more criteria are satisfied including a predefined number of cache hits for the asset when it is in the first cache. The cache service reads the asset from the second cache responsive to requests for the asset until the asset is evicted from the second cache.

  • Patent number: 10173320
    Abstract: Methods, apparatus, systems, and computer-readable media are provided for optimizing robot-implemented tasks based at least in part on historical task and location correlated duration data collected from one or more robots. Historical task and location correlated duration data may, in some implementations, include durations of different tasks performed in different locations by one or more robots in one or more particular environments, and knowledge of such durations may be used to optimize tasks performed by the same or different robots in the future.

  • Patent number: 9079115
    Abstract: A propeller connecting piece for electric model airplane, for connecting an electric-power output shaft with a propeller in an electric model airplane with the propeller, characterized in that the propeller connector comprises two connectors, wherein one of the connectors is connected with the electric-power output shaft of the model airplane, and the other connector is connected with the propeller of the model airplane, one of the two connectors is an elastic component provided with an opening slot, and the two connectors are coaxially connected and can rotate together, but can be conveniently separated from each other when impacted by external force, so as to put the propeller under effective protection.

  • Patent number: 8745074
    Abstract: Systems and methods of evaluating information via a computer network are provided. A content group can be identified, and each item of the content group can be associated with a vector indicating at least one user interest category of users exposed to the item. The vectors of each item can be evaluated to generate a first nearest neighbor list of each item of the content group. The nearest neighbor list of a first item can be compared with the nearest neighbor list of a second item. Based on a result of the comparison, the first and second items can be associated in a cluster.

  • Patent number: 8287326
    Abstract: The present invention relates to a remote controller for an aircraft model, which includes a body, a mode selection switch, and a signal acquisition unit. The body is adapted to be held in a first direction and a second direction. The mode selection switch may be configured to issue a mode selection signal. The signal acquisition unit acquires the manipulation signals manipulated by the first joystick and the second joystick in the remote controller, and processes the manipulation signals according to the mode selection signal, so as to enable the remote controller to operate respectively in the first manipulation mode and the second manipulation mode. The remote controller of the present invention merely switches the electric signals for switching between the manipulation modes without modifying the mechanical structure, thereby simplifying the switching operations.

  • Patent number: 8177600
    Abstract: A single rotor model helicopter is provided, comprising a spindle, a rotor clamp disposed on the spindle, a pair of rotor blades disposed on the rotor clamp, and a pair of hybrid control rocker arms. The helicopter further includes an operating system and a balancing system. The pair of hybrid control rocker arms are disposed on both sides of the rotor clamp respectively and rotatably connected to a pitch control rocker arm through each axial hole located on a center of each hybrid control rocker arm, so as to control attack angles of the rotor blades. Each hybrid control rocker arm has two control points. A first pair of control points diagonally opposite each other in the pair of hybrid control rocker arms are controlled by a cyclic torque transmitted from the operating system, and a second pair of control points diagonally opposite each other are controlled by the balancing system.
