Abstract: A control device may wake-up a target wireless device through a wired or wireless communications channel. In an implementation, the control device and the wireless device may include a cellular module (e.g., global systems for mobile communications (GSM) capability) to implement an on-demand wake-up call. The on-demand wake-up call may allow the control device to perform at least one task at the wireless device without user intervention at the wireless device.

Abstract: A diffuse reflection material, a diffuse reflection layer, a wavelength conversion device, and a light source system are disclosed. The diffuse reflection material includes white scattering particles and an adhesive agent, where the whiteness of the white scattering particles is greater than 85, and the white scattering particles contain high reflection scattering particles with a whiteness of greater than 90, high refraction scattering particles with a refractive index of greater than or equal to 2.0, and high thermal conductivity scattering particles, where the high thermal conductivity scattering particles are boron nitrite and/or aluminum nitride particles, and the particle shape of the high thermal conductivity scattering particles is rod-like or flat. The reduction in the thickness of the diffuse reflection layer is realized while keeping a high reflectivity, thus causing the wavelength conversion device to have both a high light efficiency and high heat stability.

Abstract: One embodiment of the present invention provides a system for facilitating dynamic load-based merging. During operation, the system identifies incremental data in memory of a first computing device. The incremental data comprises update to reference data in a storage device in a second computing device. If the size of the incremental data becomes greater than a threshold, the system selects a first server group from a plurality of server groups. The second computing device belongs to this first server group. The system then migrates data access requests from the first server group to other server groups in the plurality of server groups and merges the incremental data from the memory of the first computing device to the storage device in the second computing device. The merging includes batch sequential disk writes to the storage device of the second computing device.
