Abstract:
A method is provided for synchronizing file objects between different data centers. Here, a file system call from a virtual file system is intercepted. This file system call is associated with a file object at a data center, which is in communication with a remote data center. The intercepted file system call is then transmitted to the remote data center to synchronize a copy of the file object at the remote data center with the file object at the data center.
Abstract:
A polyimide material comprises a polyimide. The polyimide has repeating units of formula (I). The polyimide material further comprises a coupling agent-containing filler.A method for preparing a polyimide material comprises allowing a mixture comprising an aromatic tetracarboxylic dianhydride, an aromatic diamine, and a coupling agent-containing filler to react to produce a polyamic acid. The method further comprises contacting the polyamic acid with an aliphatic dicarboxylic acid of formula (II) to produce an intermediate, and imidizing the intermediate to produce the polyimide material.A polyimide comprises repeating units of formula (I).
Abstract:
A device for saving power consumption of heating and air conditioning system is provided. The energy saving device is adapted to automatically stop an air conditioner when outdoor temperature is lower than a set temperature or automatically stop a heater when outdoor temperature is higher than a set temperature. The energy saving device is provided with an outdoor temperature sensor and converter for measuring an outdoor temperature and converting the measured temperature into a first voltage value, a conversion circuit for converting a set temperature of stopping the air conditioner/heater into a second voltage value, a control circuit for controlling the air conditioner/heater, and a comparison circuit for comparing the first voltage value with the second voltage value and transmitting the result to the control circuit.

Abstract:
A process of recovering metals from waste lithium ion/Ni—H/Ni—Cd batteries, wherein the waste batteries are calcined and sieved to generate an ash containing metals and metal oxides. The process includes subjecting the ash to a first dissolution etching treatment, a first filtration treatment to obtain a filtrate containing Cd ions which are crystallized as cadmium sulfate, a second dissolution etching treatment for the filtered solid, and a second filtration treatment to obtain a second filtrate. Fe+3, Al+3 and rare earth metal ions in the second filtrate are precipitated as hydroxides by adding a base to the second filtrate. The remaining solution was extracted and counter-extracted to obtain aqueous solutions of Co and Ni ions, which were subjected separately to a electrolysis to deposit Co and Ni metals. Li ions in the residue solution from the electrolysis of Ni was precipitated as carbonate by adding a soluble carbonate salt.
Abstract:
A method and apparatus for reasonably discriminating between an appropriately behaved wireless terminal and an inappropriately behaved wireless terminal is disclosed. In particular, some embodiments of the present invention are capable of reasonably discriminating between an appropriately behaved wireless terminal and an inappropriately behaved wireless terminal even though consecutive frames have heterogeneous rates (i.e., full-rate frames, half-rate frames, quarter-rate frames, etc.).An illustrative embodiment of the present invention receives a frame from a wireless terminal and determines how many "gated-on" groups are in the frame. The illustrative embodiment next determines how many power-down commands should be issued or have been issued to the wireless terminal in response to the received frame. Next, the illustrative embodiment compares the number of power-down commands for the frame to the number of gated-on groups for the frame. When the number of power-down commands equals or exceeds the number of gated-on groups for the frame, then the frame is counted as a violator, which suggests that the wireless terminal is misbehaved.
