摘要： A method for determining a characteristic of a direct-gap semiconductor comprises measuring at least one optical constant of a first sample of a direct-gap semiconductor with an optical spectrometer, calculating an estimated value of an optical parameter of the first sample of the direct-gap semiconductor based on fitting the model αg(ln(1+e(hν-Eg)/(pEu))/ln(2))p to an optical absorption curve based on the at least one optical constant, obtaining at least one second value of the optical parameter, and calculating an estimated characteristic of the direct-gap semiconductor from the estimated value of the optical parameter and the obtained second value of the optical parameter. A method for determining a temperature of a direct-gap semiconductor and a system for determining a characteristic of a direct-gap semiconductor are also disclosed.

摘要： A group table top videoconferencing device for communication between local participants and one or more remote participants provides a camera assembly and display screens on the same housing—giving the remote participant the perception that the local participant is making direct eye-to-eye contact with him/her. The housing is placed such that the housing is within the field of view of every local participant viewing any other local participant. Because, the remote participant is always within the field of view of the local participant, the remote participant does not get the feeling of non-intimacy during the videoconference. A wall mounted display operates in conjunction with the videoconferencing device to display media content received from the remote participants. Keypad and a touch screen provide user interface for controlling the operation of the videoconferencing device. Speakers convert audio signals received from the remote participants into sound.

摘要： An overhead microphone assembly using multiple unidirectional microphone elements. The microphone assembly is installed overhead, generally above all the desired sound sources and below the undesired sound sources. The signals from these multiple microphone elements are fed into a microphone steering processor which can mix and gate the signals to ensure the best signal/noise ratio. The steering processor may also track the sound source dynamically when such tracking (source locating) is desired. The resulting audio signal from the steering processor may be further processed, such as echo canceling, noise reduction and automatic gain control.

摘要： A videoconference device provides an interface for initiating and controlling a videoconference and incorporating and annotating content in the videoconference without a personal computer. The content may reside on a portable storage medium such as a Universal Serial Bus (USB) or other flash memory device inserted in the interface device or on the device itself. The interface device may be a dedicated device for controlling the videoconferencing system, navigating to desired content, and interacting with the shared content. The device may also be a portable device such as a tablet device or mobile phone that interfaces with a videoconference system via an installed application.

摘要： A videoconferencing system includes a first videoconferencing unit coupled to a network and associated with a first instant messaging identity. The first videoconferencing unit obtains a second instant messaging identity and automatically sends a request instant message requesting videoconferencing connection information to the second instant messaging identity. A second videoconferencing unit is coupled to the network and is associated with the second instant messaging identity. The second videoconferencing unit receives the request instant message and automatically returns a response instant message including videoconferencing connection information to the first instant messaging identity. The first videoconferencing unit receives the response instant message and automatically obtains the videoconferencing connection information from the response instant message. Using the videoconferencing connection information, the first videoconferencing unit initiates a videoconference call with the second videoconference unit.
