Abstract: A tone detector is disclosed that is realizable in digital embodiment on a single integrated circuit die and does not require external components, such as a discrete capacitor. An input connects to a comparator, which in turn connects to one or more edge detectors and a flip flop. The edge detector outputs a pulse responsive to a detected edge. A counter is reset by the pulses from the edge detectors thereby preventing the counter from reaching a maximum value, which would otherwise be output from the counter and provided to a flip flop to clock in the comparator output at the D input to the flip flop. In operation, the comparator generates a rail to rail signal responsive to a received tone, which in turn is clocked through the flip flop as a logic high output indicating presence of a tone.

Abstract: A method and system for reducing power consumption of an electronic circuit design using an EDA tool includes generating a look-up table (LUT) that stores a mapping between a type, a predetermined optimum power input transition time, and at least one characteristic corresponding to each digital logic element present in a cell library of the EDA tool. An input transition time of a first digital logic element is determined. Then, the first logic element is replaced with a second logic element if the input transition time and the predetermined optimum power input transition time of the first logic element are not equal. The second logic element may be replaced with a third logic element if a timing delay of the second logic element is greater than a timing delay of the first logic element.

Abstract: A system and a method for analyzing conversational data comprising colloquial or informal terms and having an informal structure. A corpus of training language maps, each associated with an entity, is generated from conversational data retrieved from sources previously associated with entities. Subsequently received conversational data is processed to generate a conversational language map which is compared to a plurality of the stored training language maps. A confidence value is generated describing the similarity of the conversational language map to each of the plurality of the stored training language maps. The entity associated with the training language map having the highest confidence value is then associated with the conversational language map.

Abstract: An in-vivo examining device, system and method for identifying the presence of strictures in the small bowel are provided. The in-vivo examining device includes a monitoring mechanism that becomes deactivated when exposed to in-vivo substances native to the small bowel or the colon, and a degradable device body that includes at least a first body portion which degrades at a slow rate when exposed to in-vivo substances native to the small bowel and at a fast rate when exposed to in-vivo substances native to the colon. The degradation of the degradable device body exposes the monitoring mechanism to substances native to the small bowel or the colon and thus indicates whether the examining device has safely passed through the small bowel or whether it is retained in the small bowel due to strictures in the small bowel.

Abstract: A method for preventing a fuel cell voltage potential reversal including determining a relationship between the cell resistance and the current of a fuel cell stack at which a fuel cell voltage potential reversal will occur, operating the fuel cell stack according to a power demand requested, and determining the maximum cell resistance of the fuel cells in the stack.
