An iterative process is provided for interacting with a voice information service. Such a service may permit, for example, a user to search one or more databases and may provide one or more search results to the user. Such a service may be suitable, for example, for searching for a desired entity or object within the database(s) using speech as an input and navigational tool. Applications of such a service may include, for instance, speech-enabled searching services such as a directory assistance service or any other service or application involving a search of information. In one example implementation, an automatic speech recognition (ASR) system is provided that performs a speech recognition and database search in an iterative fashion. With each iteration, feedback may be provided to the user presenting potentially relevant results. In one specific ASR system, a user desiring to locate information relating to a particular entity or object provides an utterance to the ASR. Upon receiving the utterance, the ASR determines a recognition set of potentially relevant search results related to the utterance and presents to the user recognition set information in an interface of the ASR. The recognition set information includes, for instance, reference information stored internally at the ASR for a plurality of potentially relevant recognition results. The recognition set information may be used as input to the ASR providing a feedback mechanism. In one example implementation, the recognition set information may be used to determine a restricted grammar for performing a further recognition.

There is provided a semiconductor device in which fabrication steps can be reduced by constructing a circuit using only TFTs of one conductivity type and in which a voltage amplitude of an output signal can be normally obtained. A capacitance (205) is provided between a gate and a source of a TFT (203) connected to an output node, and a circuit formed of TFTs (201) and (202) has a function to bring a node a into a floating state. When the node α is in the floating state, a potential of the node a is caused higher than VDD by using gate-source capacitance coupling of the TFT (203) through the capacitance (205), thus an output signal having an amplitude of VDD-GND can be normally obtained without causing amplitude attenuation due to the threshold value of the TFT.

In order to maintain the integrity of data stored in a flash memory that are susceptible to being disturbed by operations in adjacent regions of the memory, disturb events cause the data to be read, corrected and re-written before becoming so corrupted that valid data cannot be recovered. The sometimes conflicting needs to maintain data integrity and system performance are balanced by deferring execution of some of the corrective action when the memory system has other high priority operations to perform. In a memory system utilizing very large units of erase, the corrective process is executed in a manner that is consistent with efficiently rewriting an amount of data much less than the capacity of a unit of erase.

In a memory system utilizing very large units of erase, the corrective process is executed in a manner that is consistent with efficiently rewriting an amount of data much less than the capacity of a unit of erase. Data is rewritten when severe errors are found during read operations. Portions of data are corrected and copied within the time limit for read operation. Corrected portions are written to dedicated blocks.

A semiconductor device having a normal function means is provided, in which the amplitude of an output signal is prevented from being decreased even when a digital circuit using transistors having one conductivity is employed. By turning OFF a diode-connected transistor 101, the gate terminal of a first transistor 102 is brought into a floating state. At this time, the first transistor 102 is ON and its gate-source voltage is stored in a capacitor. Then, when a potential at the source terminal of the first transistor 102 is increased, a potential at the gate terminal of the first transistor 102 is increased as well by bootstrap effect. As a result, the amplitude of an output signal is prevented from being decreased.

A circuit is provided which is constituted by TFTs of one conductivity type, and which is capable of outputting signals of a normal amplitude. When an input clock signal CK1 becomes a high level, each of TFTs (101, 103) is turned on to settle at a low level the potential at a signal output section (Out). A pulse is then input to a signal input section (In) and becomes high level. The gate potential of TFT (102) is increased to (VDD−V thN) and the gate is floated. TFT (102) is thus turned on. Then CK1 becomes low level and each of TFTs (101, 103) is turned off. Simultaneously, CK3 becomes high level and the potential at the signal output section is increased. Simultaneously, the potential at the gate of TFT (102) is increased to a level equal to or higher than (VDD+V thN) by the function of capacitor (104), so that the high level appearing at the signal output section (Out) becomes equal to VDD. When SP becomes low level; CK3 becomes low level; and CK1 becomes high level, the potential at the signal output section (Out) becomes low level again.

A Point-of-Entry Kiosk loyalty system, couponing system, and shopping list system is provided so when a consumer enters a store, kiosk(s)s may be present for consumer check-in. When at or within proximity of the kiosk (e.g., from an RFID enabled cell phone) the consumer may log in or be recognized. The consumer may swipe a coded loyalty card, enter their loyalty number or data may be automatically entered through RFID technology or smart phone. The consumer may be presented with discount or coupon offers or shopping suggestions, which may be based on the consumer's prior preferences, demographic data, prior purchases, or preference data harvested from various social networking sites, search engines, or other websites used by the consumer.

A convenience controller activates a small zone high location precision welcoming detecting function (with high current utilization) in response to a detected arrival of an authorized user into a larger zone low location precision welcoming detecting function (with low current utilization) approach region around a vehicle. A short range transmitter broadcasts a polling signal covering the region. The short range transmitter has an approach pending mode wherein the polling signal is broadcast according to a first predetermined repetition and a baseline mode wherein the polling signal is broadcast according to a lower repetition. The short range transmitter has a first power drain in the approach pending mode. A wireless communication system is configured to monitor for user activity outside the approach region corresponding to a potential user entry into the approach region, wherein monitoring by the wireless communication system has a lower power drain. If the short range transmitter is in the baseline mode when the user activity is detected, then the short range transmitter switches to the approach pending mode.

A method for and devices utilizing monolithic integration of enhancement-mode and depletion-mode AlGaN/GaN heterojunction field-effect transistors (HFETs) is disclosed. Source and drain ohmic contacts of HFETs are first defined. Gate electrodes of the depletion-mode HFETs are then defined.

Device isolation is achieved by either mesa etching or fluoride-based plasma treatment. This method provides a complete planar process for GaN-based integrated circuits favored in high-density and high-speed applications.

It is an object to decrease the number of transistors connected to a capacitor. In a structure, a capacitor and one transistor are included, one electrode of the capacitor is connected to a wiring, and the other electrode of the capacitor is connected to a gate of the transistor. Since a clock signal is input to the wiring, the clock signal is input to the gate of the transistor through the capacitor. Then, on/off of the transistor is controlled by a signal which synchronizes with the clock signal, so that a period when the transistor is on and a period when the transistor is off are repeated. In this manner, deterioration of the transistor can be suppressed.
