The present invention relates to a method of preparing a Li film, wherein said Li film is fabricated by directly decomposing a compound of Li under a vacuum evaporation condition, and said compound is Li3N. Said Li film is fabricated by decomposing Li3N at an evaporation rate of 0.01-0.25 nm/s and an evaporation temperature of 300-450° C., and said Li film has a thickness of 0.3-5.0 nm. The present invention also relates to an organic light emitting device comprising said Li film as an electron injection layer and a method for the preparation thereof, and an organic light emitting device including an electron injection layer comprising an electron transport material doped with Li obtained by decomposing Li3N under a vacuum evaporation condition, and a method for the preparation thereof.

Techniques described herein may recognize handwritten characters that are written at least partially over the top of one another that are input to a computing device. The handwritten characters may be formed of one or more strokes. A user may write characters or parts of words over approximately the same area of graphical user interface (i.e., on top of each other) without having to wait for a timeout between character input and without having to select a button or provide another input indicating the character is complete before entering input for another character. Once a character is at least partially recognized, a graphical indication corresponding to the user input displayed on a screen may be altered. Such alterations may include fading or changing size or location of the graphical indication.

A transmission gate-based spin-transfer torque memory unit is described. The memory unit includes a magnetic tunnel junction data cell electrically coupled to a bit line and a source line. A NMOS transistor is in parallel electrical connection with a PMOS transistor and they are electrically connected with the source line and the magnetic tunnel junction data cell. The magnetic tunnel junction data cell is configured to switch between a high resistance state and a low resistance state by passing a polarized write current through the magnetic tunnel junction data cell. The PMOS transistor and the NMOS transistor are separately addressable so that a first write current in a first direction flows through the PMOS transistor and a second write current in a second direction flows through the NMOS transistor.

A fluid dynamic bearing formed by a microelectromechanical systems (MEMS) wafer-level batch-fabrication process is provided. The process results in a high performance and high reliability fluid dynamic bearing having features including higher bearing lifetime at high RPM, improved bearing stiffness, durability and thrust/restoring forces capabilities. The present invention is especially useful with small form factor disc drive memory devices having constraints in motor height, such as a 2.5 inch disc drive, requiring high performance including high rotational speed and large areal density. A sacrificial layer is utilized in the process to simultaneously form symmetrical facing surfaces of relatively rotatable components. The facing surfaces define, therebetween, a desired feature, such as a journal bearing, a thrust bearing, a fluid channel, a fluid reservoir, a capillary seal, pressure generating grooves, and other profile geometries. Such geometry control allows for design freedom in obtaining a desired bearing performance and stiffness.

The present invention discloses a method and an apparatus for coexistence of multiple operating entity systems, where the method includes: setting part or all of bandwidths of an operating entity in uplink timeslots of a downlink carrier frequency interference region to be in an idle state. By using the present invention, the uplink timeslots of the operating entity in the downlink carrier frequency interference region are set to be in an idle state and do not transmit an uplink transmit signal any longer, which prevents a downlink transmit signal of another operating entity from interfering with an uplink transmit signal of the operating entity.
