Abstract: A computer system displays a first object that includes at least a first portion of the first object and a second portion of the first object and detects a first gaze input that meets first criteria, wherein the first criteria require that the first gaze input is directed to the first portion of the first object in order for the first criteria to be met. In response, the computer system displays a first control element that corresponds to a first operation associated with the first object, wherein the first control element was not displayed prior to detecting that the first gaze input met the first criteria, and detects a first user input directed to the first control element. In response to detecting the first user input directed to the first control element, the computer system performs the first operation with respect to the first object.

Abstract: A distributed switching system comprising a call controller, multiple source modules, and multiple destination modules provides circuit switching functionality without using a centralized circuit switch. When a source module of the multiple source modules receives inbound data, the source module broadcasts the data to each destination module of the multiple destination modules via an inbound time slot of multiple inbound time slots. The call controller selects a destination module of the multiple destination modules to process the data and informs the selected destination module of the inbound time slot. The selected destination module then receives the broadcast via the inbound time slot and processes the broadcast data. The distributed switching system further provides for a transfer of data in an outbound direction by allocating an outbound time slot in which the selected destination module embeds tagged data for receipt and forwarding by the source module.

Abstract: Line terminal equipment (30, 35) transmits health and status information (66, 68) to bearer payload processors (50-N). Each bearer payload processor (50-N) concatenates (96) the health and status information of the line terminal equipment. Each bearer payload processor transmits the concatenated health and status information including bearer traffic to each of the line terminal equipment (30, 35). Both the line terminal equipment and bearer payload processors compare (98, 100) the health and status information.

Abstract: An automatic protection arrangement for a communication system (100) provides a working line terminal equipment (300 and a link (1A) for transmitting bearer traffic from a number of bearer payload processors (50-N) to a switching center (10). The arrangement also has a protection line terminal equipment (35) and link (2A) coupled to the switching center (10). For detected faults, an instantaneous switch over occurs of the bearer traffic of the bearer payload processors (50-N) from the working line terminal equipment (30) to the protection line terminal equipment (35).
