Abstract: Embodiments of the present invention enhance the search experience of a user by looking at the search history of one or more friends to provide search enhancements to the user. The search enhancements may also be based on information within a user's online social network. Search enhancements based on the user's online social network include identifying people within the user's social network that may have information relevant to a query, posts within the social network that are relevant to the query, and feed items. Examples of search enhancements include an annotation or graphic adjacent to a search result indicating the search result has been visited by one of the user's friends. In another aspect, alternative queries from the friends' search history may be suggested to the user during the search session.

Abstract: Embodiments of the present invention enhance the search experience of a user by looking at the search history of one or more buddies to provide search enhancements to the user. Examples of search enhancements include an annotation or graphic adjacent to a search result indicating the search result has been visited by one of the user's buddies. In another embodiment, the relevance score assigned to a search result is increased if the search result has been visited by a buddy. In another aspect, alternative queries from the buddies' search history may be suggested to the user during the search session.

Abstract: The invention presents a system and method for reserving space within a browser for a requesting component. The invention can reserve space above, below, to the right, or to the left of a main browsing section for a requesting component. The invention can adjust the main browsing section in order to fit a plurality of spaces created for requesting components. The spaces reserved can be presented in a manner that does not obstruct any viewable areas of the main browsing section.

Abstract: An oscillator circuit is coupled to receive first and second reference signals and includes a voltage-controlled oscillator for generating an oscillating signal. A difference frequency calculation circuit is coupled to the voltage-controlled oscillator to produce a count signal corresponding to a difference in frequency between the oscillating signal and the first reference signal. A feedback circuit is coupled to the difference frequency calculation circuit and coupled to receive the second reference signal which corresponds to a predetermined frequency for the oscillating signal. The feedback circuit provides a control signal as an input to the voltage-controlled oscillator to control the frequency of the oscillating signal.

Abstract: A frequency divider uses a single D flip-flop integrated circuit having an inverted output and an asynchronous clear input between which a feedback loop comprising a delay Tau is connected. The frequency divider receives a multi-GHz input frequency f.sub.1, and divides by any integer N to produce an output frequency f.sub.2 =f.sub.1 /N using the internal delay of the D flip-flop between input and output (CK-to-Q), and the internal delay between the asynchronous clear input to the output (CLR-to-Q). Solving for the amount of delay Tau in the feedback loop necessary to produce the desired integer, or divide ratio, N, according to a predetermined formula is also required. An integrated circuit D flip-flop manufactured by Gigabit Logic is preferably selected to provide the high input frequency capability, external to which is added the feedback loop for determining the divide ration desired. The divide ratio, or integer by which the input frequency is divided, includes the ability to divide by a non-2.sup.
