    Abstract: A accurate time measurement circuit. The design is amenable to implementation as a CMOS integrated circuits, making the circuit suitable for a highly integrated system, such as automatic test equipment where multiple time measurement circuits are required. The circuit uses a delay locked loop to generate a plurality of signals that are delayed in time by an interval D. The signal to be measured is fed to a bank of delay elements, each with a slightly different delay with the difference in delay between the first and the last being more than D. An accurate time measurement is achieved by finding coincidence between one of the TAP signals and one of the delay signals. The circuit has much greater accuracy than a traditional delay line based time measurement circuit with the same number of taps. It therefore provides both accuracy and fast re-fire time and is less susceptible to noise.

    Abstract: A method of processing speech representative of ideograms for speech communication using an asynchronous communication channel (21) is disclosed. The method includes the step of processing speech units of a speech and data indicative of the speech units. Each speech unit is representative of an ideogram or a plurality of semantically related ideograms (500-508). The data indicative of the speech units is discretely communicable on the asynchronous communication channel (21). By communicating the data indicative of the speech units, a substantially low data transmission rate and intelligible speech communication is achieved.

    Abstract: A method of providing an ad extension includes selecting an advertisement for display. The method also includes selecting additional information related to the advertisement. The method also includes transmitting data representing the advertisement to a browser. The browser interacts with an expandable API to render an inline frame having an advertisement slot. The browser renders and displays the advertisement in the frame. The method also includes transmitting display data representing the additional information related to the advertisement to the browser. The browser receives an input to activate the ad extension. In response to the input, the browser interacts with the expandable API system to expand and render the frame. The browser renders, in the frame, the advertisement slot containing the advertisement. The browser also renders, in the frame, the additional information. The browser displays the expanded inline frame, such that the displayed frame covers a portion of the content.
