TL;DR: In this article, an interaction simulator is connected with an external database, such as an electronic program guide, and information gathered during interaction, particularly conversational, is parsed and used to augment the database data.
Abstract: An interaction simulator, such as a chatterbot, is connected with an external database, such as an electronic program guide The information gathered during interaction, particularly conversational, is parsed and used to augment the database data The interaction simulator may be guided by the data residing in the database so as to help fill in recognizable gaps by, for example, intermittently asking questions relating to the subject data requirement The interaction simulator may be provided with specific response templates based on the needs of the database and a corresponding set of templates to extract the information required by the database Another example database may be for recording and indexing by key word stories or other free-form verbal data uttered by the user The interaction simulator may be programmed to help the user develop the story using templates designed for this purpose

TL;DR: In this paper, a high frequency inverter (20) and an impedance circuit (30) are used to produce a high-frequency voltage source whereby the impedance circuit directs a flow of alternating current through a LED array (40).
Abstract: A LED driver (10) is disclosed. The LED driver (10) includes a high frequency inverter (20) and an impedance circuit (30). The high frequency inverter (20) operates to produce a high frequency voltage source whereby the impedance circuit (30) directs a flow of alternating current through a LED array (40) including one or more anti-parallel LED pairs, one or more anti-parallel LED strings, and/or one or more anti-parallel LED matrixes. A transistor (T3) can be employed to divert the flow of the alternating current from the LED array (40), or to vary the flow of the alternating current through LED array (40).

TL;DR: In this paper, a wireless power transfer system includes a power receiver (105) and a power transmitter (101) generating a wireless inductive power transfer signal for powering the power receiver during a power transfer phase.
Abstract: A wireless power transfer system includes a power receiver (105) and a power transmitter (101) generating a wireless inductive power transfer signal for powering the power receiver (105) during a power transfer phase. An apparatus, often the power transmitter (101) comprises a first communication unit (305) communicating with a second communication unit of an entity using an electromagnetic communication signal. The entity may typically be the power receiver (105). The apparatus comprises a reference processor (307) for measuring and storing a reference value of a characteristic of the communication signal and a measurement unit (309) which repeatedly during the power transfer phase determines a measured value of the characteristic. A comparator (311) compares the measured values to the reference value and an initiator (313) triggers an entity detection process if the comparison indicates that a measured value and the reference value do not meet a similarity criterion. The entity detection process detect a presence of another entity.
