摘要:
In a broadband communication system there are multi-stage power amplifier systems for amplifying the power of radio-frequency (RF) communication signals. Each stage of the amplifier system results in composite triple beat (CTB) distortion, and if the phase of the CTB distortions are approximately the same (i.e. are in-phase), then the amplitudes of the distortions are added (i.e. null20 dBnull rule). The amplifier system of the invention includes one or more phase filters positioned in series between the power amplifier stages. The phase filters are adapted to shift the phase of the communication signals, so that the phase of CTB distortions, resulting from the amplification of the communication signals in the amplifier stages between the phase filters, are substantially different (i.e. are out-of-phase). Thus, only the power of the CTB distortions are added (i.e. null10 dBnull rule).
摘要:
A system and method for directing an incoming telephone call. The system comprises a control unit that receives images associated with two or more regions of a local environment. The two or more regions are each serviced by a respective telephone extension. The control unit processes the images to identify, from a group of known persons associated with the local environment, any one or more known persons located in the respective regions. For each known person so identified, an indicium is generated that associates the known person with the respective region in which the known person is located.
摘要:
A system having a video display screen that provides video to a user. The position of the display screen is adjustable based upon the location of the user with respect to the display screen. The system includes at least one image capturing device trainable on a viewing region of the display screen and coupled to a control unit having image recognition software. The image recognition software identifies the user in an image generated by the image capturing device. The software of the control unit also generates at least one measurement of the position of the user based upon the detection of the user in the image.

A media player controller is disclosed that monitors user activity and automatically controls a media player in response to predefined events. The disclosed media player controller includes one or more audio/visual mage capture devices focused on one or more users. The captured audio and video information is processed by the media player controller to identify one or more predefined events. A number of rules can be utilized to define various user events, such as when the user has left the room, is on the telephone or is otherwise paying attention to the media player. Each rule contains one or more conditions, and, optionally, a corresponding action-item that should be performed when the rule is satisfied. Upon detection of a predefined event, the corresponding action, if any, is performed by the media player controller.

A method and apparatus are disclosed for monitoring traffic using vision-based technologies to recognize events and violations. The disclosed traffic monitoring system includes one or more image capture devices focused on a roadway where vehicles travel. The captured images are processed by the traffic monitoring system to identify one or more predefined events or traffic violations. A number of rules can be utilized to define various traffic-related events, including traffic violations. Each rule contains one or more conditions, and, optionally, a corresponding action-item that should be performed when the rule is satisfied. Upon detection of a predefined traffic event, the corresponding action, if any, is performed by the traffic monitoring system.
摘要:
A protective sleeve of quartz surrounding a metal halide arc tube is fixed to upright portions of a frame by means of retaining rings. The frame has lower ends formed with coils fitted over the glass stem in an interference fit, thereby insulating the frame from the electrical leads sealed in the stem. An intermediate portion of the frame fits closely in the opposite end of the lamp to stabilize the burner assembly and shield.
摘要:
A decision support system for managing an agile supply chain including a server side and a client side. The server side includes a decision support system database that interfaces with a model engine that performs analysis of the data to support planning decisions. The server side also includes a server manager that coordinates requests for service and information. The client side includes decision frames that present the various view points available in the system to the users. A frame manager coordinates the requests from the decision support frames to access the needed data and models.

Disclosed is a process for making a self-aligning conductive via structure in a semiconductor device. The process includes forming a first interconnect metallization layer over an oxide layer. Forming an etch stop layer over the first interconnect metallization layer. Forming a conductive via metallization layer over the etch stop layer. Forming a hard mask layer over the conductive via metallization layer. The process further includes producing a conductive via and an interconnect line, where the conductive via is formed from a portion of the conductive via metallization layer, and the interconnect line is formed from a portion of the first interconnect metallization layer. The conductive via is substantially aligned with the underlying interconnect line.
摘要:
A system extracts, from uncoded video data, coding parameters that correspond substantially to coding parameters used in a coding operation that was previously performed on the video data. The system generates a histogram for at least one AC frequency band in the uncoded video data and calculates a correlation function for the histogram. A maximum value of the correlation function is then identified, and a coding parameter for the at least one AC frequency band is determined using the maximum value of the correlation function.
