摘要:
A method and apparatus for conferencing two or mores calls in an expandable telecommunications system. The system may include a plurality of nodes connected by an inter-nodal network such that the nodes communicate with each other by exchanging variable-length packets of information. At least one node in the system contains digital signal processing circuitry capable of conferencing the voice information from three or more callers interfaced with the system. Packets containing voice information from each conference participant are preferably transmitted via the inter-nodal network to the node having the requisite digital signal processing circuitry. This node performs a conferencing function on that information, packets the resulting conferenced information and transmits those packets via the inter-nodal network to the nodes interfaced with the conference participants.

In one embodiment, graphics from a general-purpose computer are mixed with video images from a video source. A first interface receives the graphics, the graphics including a plurality of graphics frames, at least some graphics frames including one or more regions having pixels set to one or more predetermined color values. A second interface receives video images from the video source, each video image corresponding to one of the plurality of graphics frames. A video mixer includes logic configured to recognize pixels in the at least some graphics frames that are set to the one or more predetermined color values, and in the one or more regions where the pixels are set to the one or more predetermined color values to mix pixels from the corresponding video image with the graphics frame, to create a plurality of mixed images. One or more output interfaces outputs the mixed images.

In one embodiment, a multimedia control and distribution architecture is provided. A media server/controller generates a plurality of graphics signals, each graphics signal including a separate user interface to be displayed on a particular device, such as a touch screen unit. A universal extender (UVX) coupled to the media server/controller converts and extends the graphics signals for transmission on a plurality of universal transmission pathways. Each of the plurality of devices receives a graphic signal passed thereto, displays graphics embodied in the graphics signals, and accept user input in response to the graphics signal. For example, the one or more touch screen units may accept a user touch and pass a location of the user touch back on a universal transmission pathway to the UVX, for transmission to the media server/controller. The media server/controller generates control commands and provides the control commands.

Structure for isolating a kennel run from wash water and other waste from an adjacent run. An upwardly opening channel is sealed to the floor between the runs, and a partition is supported directly above this channel with its lower edge essentially in the channel, so that waste cannot pass above or below the channel, and so that the waste runs from the partition into the channel.

This invention relates to an object detection system and device for detecting objects located on storage sections, and in particular a lower storage section, of a moving shopping cart. The system and device comprise a detecting means which detects objects on the storage sections of shopping carts when the shopping cart moves into a predetermined position. The detecting means generates a detection signal if an object is detected. The detecting means operates in response to a trigger signal which is sent from a triggering means. The triggering means is operable to sense at least one, and preferably two parts of the shopping cart when the shopping cart moves into the predetermined position. The triggering means sends the triggering signal when it senses the presence of a cart or other body. The preferred triggering embodiment senses three spaced-apart portions of the cart, to minimize erroneous operation of the system by objects other than a cart of predetermined character.

A system which allows a user to teach a computational device how to perform complex, repetitive tasks that the user usually would perform using the device's graphical user interface (GUI) often but not limited to being a web browser. The system includes software running on a user's computational device. The user “teaches” task steps by inputting natural language and demonstrating actions with the GUI. The system uses a semantic ontology and natural language processing to create an explicit representation of the task that is stored on the computer. After a complete task has been taught, the system is able to automatically execute the task in new situations. Because the task is represented in terms of the ontology and user's intentions, the system is able to adapt to changes in the computer code while still pursuing the objectives taught by the user.

The switch has a passive section and an active section or tray that may be docked to the passive section. The passive section contains only the physical interfaces to the switch's external data and telephony networks and power input. It is not intended to be a field replaceable unit and is therefore intended to be mounted in a rack system with all of the power and communications cables attached thereto. The telephony and data ports are routed from the passive section to the active section via connectors on the two sections as well as to a redundancy connector on the passive section that may be physically connected by a cable to a slave unit in a redundant application. The active section or tray contains all of the active components of the switch and is inserted via guides into the passive section. The tray is considered a field replaceable unit and can be inserted into and extracted from the passive section while the system is powered up and operational. As a result of its unique two-section design, the present switch has several advantages. For example upon failure, all active components of the system may be replaced without removing the mounting hardware from the rack in which the switch is mounted and without removing any cables connected to the switch. Also when the switch is part of a redundant system, when the switch fails, all of the active components of the switch may be replaced without interrupting system operations.

A telecommunications switch includes a plurality of digital signal processing modules resident on a communications services card, wherein each module includes its own time slot interchange (TSI). Significantly, this allows each digital signal processing module to simultaneously receive all information transmitted from the line cards. In addition, since each digital signal processing module includes its own dedicated TSI and each of these TSIs is connected in parallel to the same TDM bus, one or more TSIs may simultaneously output data onto the TDM bus during a time slot. Advantageously, this allows multiple TSIs to be assigned to the same transmit time slot and mux transmit time slots at the bit level. For example, if a first TSI on the digital signal processing module needs only three bits of an eight bit time slot, and a second TSI needs five or less bits, then both TSIs can be assigned to transmit during the same time slot. The first TSI would output data on, for example, the three least significant bits, while the second TSI would output its data onto the remaining bits of the time slot.
