Abstract: A communication server and accompanying communication devices allow near instantaneous communication between users of the communication devices. A communication device may be configured with multiple channels, where each channel is assigned a corresponding communication device. As the communication devices are registered with the communication server, each communication device has knowledge of other registered communication devices. Thus, communication devices may communicate nearly instantaneously with each other. Furthermore, as the communication device is equipped with multiple channels, a single communication device may host a conference call with other communication devices. In addition, communication device may include multiple buttons to control the communication device, and indicator lights to indicate the status of calls with other communication devices.

Abstract: A three-section slide rail device includes an outer section, a middle section and an inner section. The middle section includes a middle rail and an inner middle block. The inner section includes an inner rail slidably disposed on the middle rail, and a removal operating assembly disposed on the inner rail. The removal operating assembly has a removal operating member, a removal connecting plate and a removal locking member pivotably mounted on the inner rail and having a removal guiding slot. The removal locking member has a locking portion and a protrusion. The removal operating member is operated to move the removal connecting plate and bring the protrusion to move along the removal guiding slot to result in pivoting of the removal locking member so as to disengage the locking portion from the inner middle block for permitting removal of the inner section from the middle section.

Abstract: An integrated structure according to a preferred embodiment may include a silicon or silicon-on-insulator (SOI) substrate, a conductive layer spaced apart from the substrate and including a metal or a metal compound, and a diffusion barrier layer provided therebetween. The substrate and the diffusion barrier layer may directly contact and form a van der Waals junction. Since the diffusion barrier layer may block diffusion of metal atoms into the substrate lattice by blocking movement of materials (atoms) between the substrate and the conductive layer and may also control injection of holes from the conductive layer toward the substrate, defects at the metal-semiconductor interface may be controlled to overcome the limitations of ultra-fine and highly integrated semiconductors.
