20140050935 | POLYIMIDE FILM INCORPORATING POLYIMIDE POWDER DELUSTRANT, AND MANUFACTURE THEREOF - A polyimide film includes a polyimide layer including a polyimide base polymer, and a polyimide powder distributed in the polyimide base polymer, the polyimide powder being obtained by reacting a diamine with a dianhydride at a molar ratio of about 1:0.950 to about 1:0.995. Moreover, the polyimide film may have a multilayered structure including at least a second polyimide layer stacked on a surface of the polyimide layer. The second polyimide can also include the polyimide powder at a weight ratio less than about 20 wt % of the total weight of the second polyimide layer. Embodiments described herein also include methods of preparing the polyimide films. | 02-20-2014 |

20150229598 | METHOD AND SYSTEM OF SYNCHRONING AN UNREAD MESSAGE IN INSTANT COMMUNICATION - A method and a system of synchronizing an unread message of instant communication are disclosed. The method includes: obtaining information of an unread message in each dialogue associated with an instant messaging account from a server when the account is logged in via a current terminal; and displaying the information of the unread message in the current terminal, wherein the unread message is a message with time information that is larger than a first time stamp in each dialogue, the first time stamp being time information of a most recently read message in each dialogue submitted by the instant messaging account, and the first time stamp corresponding to each dialogue of the instant messaging account being stored in the server. The embodiments of the present disclosure avoid the problem of repeatedly sending unread messages among different terminals and the problem of failing to synchronize statistical information of the unread messages, thus reducing the system resource occupancy in a server and a terminal, achieving a seamless synchronization of information associated with the unread messages among the different terminals, and improving the experience of a user. | 08-13-2015 |

20110048861 | HOIST POSITIONING SYSTEM AND METHOD - A hoist positioning system includes an accelerometer attached to a hoist, a control unit for processing signals from the accelerometer and comparing the processed signals with reference data to determine a position of the hoist, a drive system for moving the hoist up and down, and a relay that is switched ON and OFF by a control signal from the control unit. When the relay is switched ON, power is supplied to the drive system from a high-voltage power source and the hoist is driven up or down. When the relay is switched OFF, power from the high-voltage power source to the drive system is cut off and the hoist stops moving up or down. | 03-03-2011 |
