    摘要： The disclosure provides a method and a system for network handover. The method includes: during a process that equipment hands over from a current network to another network, a driver receiving a network-disconnected message, and judging whether the network-disconnected message is sent from a Connection Manager (CM); if the network-disconnected message is sent from the CM, the driver reporting, to an operating system, a first signalling which identifies that the current network is disconnected; and if the network-disconnected message is not sent from the CM, the driver reporting, to the operating system, a second signalling which identifies that the current network is connected. By the adoption of the method and the system, power consumption of the equipment can be reduced.

    摘要： This disclosure describes a wearable fall detection device configured to utilize several methods that facilitate monitoring a wearer of the device. The device comprises a first sensor configured to generate elevation data that represents an elevation of the device, and a second sensor configured to generate acceleration data that represents a magnitude of acceleration of the device. The device also includes a processor configured to determine, based on the elevation data, an elevation of a floor located underneath the wearer, and detect a fall affecting the wearer. Detecting a fall may be done by determining that the acceleration data satisfies a fall hypothesis condition, and determining, based on the elevation data, that the apparatus is vertically displaced from the floor by less than a threshold distance.

    摘要： There are provided methods and systems for precisely controlling the surfactant concentration and character of ferroelectric nanoparticles in a ferroelectric liquid crystal dispersion. In an aspect, the invention provides an efficient FTIR technique to characterize the status and measure the distribution of the surfactant in ferroelectric particle dispersion. This allows for establishing a reproducible fabrication process for ferroelectric nanoparticle liquid crystal dispersions. The methods also maintain the nanoparticles ferroelectricity, which is provided by the addition of surfactant during a comminution process. The invention therefore optimizes both the milling time (to achieve small particle size and narrow size distribution) and surfactant concentration (to maintain the ferroelectricity during milling).
