Adaptive programming method and apparatus for flash memory analog storage. The present invention method is to adjust the voltage of the programming pulse each time based on the result of the previous pulse. The expected change in the programmed value is compared to the measured change, and the difference used to improve the model of that cell after each programming pulse. The algorithm is "adaptive" because the voltage of each pulse is adapted to whatever the cell needs. If the cell is programming too slowly, the voltage is increased dramatically to make it faster. Conversely if the results show that a particular cell is programming too fast, the next voltage pulse is increased by only a small amount (or even decreased if necessary). Because the response of the cell is non-linear, a special analog circuit is used to calculate the optimum voltage for each pulse. As one alternative, a digital calculation may also be used to program the cells. Because of the programming speed of the exemplary method, a voice signal may be sampled and stored in flash memory one cell at a time. Variable programming parameters other than voltage may be used if desired.

An item velocity monitoring system is provided which interfaces with a consumer retail store that has several cash registers that are tied into a “point of sale” store controller. The item velocity monitoring system is capable of detecting when sales (or other movement activities) of an item are occurring too quickly, or too slowly. The item velocity monitoring system is first “trained” in a learning mode of operations, during which item patterns and group patterns are evaluated and placed into a pattern database. The system then compares the observed item velocity to its model probability velocity, and if the observed item velocity deviates beyond the statistical model, a “velocity event” is generated, declaring one of the above selling “too quick” or “too slow” conditions. Once a velocity event is detected, an event handling routine displays the event, and can transmit the event information over a network (including the INTERNET) to a remote computer for additional analysis or record keeping. A “Loyalty Out-of-Stock System,” (LOSS) is incorporated in the above item velocity monitoring system which automatically detects when items for sale are out-of-stock (OOS), discovers the reasons for these “stock-outs,” and determines how customers react to these stock-outs. The LOSS operates on store data and models the expected item movement rate for each item under varying time-of-day, day-of-week, price, promotion, season, holiday, and market conditions; detects items that are moving abnormally slowly, thereby identifying items that may be improperly displayed; provides early warning that an item may go out-of-stock (OOS) by detecting items with abnormally high movement; detects and reports on items that are OOS at retail stores; summarizes OOS events for the store and retail chain management, and for suppliers, thereby identifying items that are over-stocked (too few OOS events), under-stocked (too many events), badly re-stocked (too long events); analyzes the OOS events to find patterns that explain why OOS's are occurring; and determines the impacts of these OOS events on store customers, thereby measuring losses to the retailer and supplier, and establishing the loyalty of consumers to the item, brand, and chain.

Systems and methods are provided for motion detection and capture control of video data from a capsule camera system having an on-board storage. The capsule camera system moves through the GI tract under the action of peristalsis and records images of the intestinal walls. The capsule's movement is episodic and jerky. The capacity of the on-board storage is limited. In order to avoid unnecessary capture of images when the capsule camera moves very slowly or stalls, motion detection technique is utilized to help control image capture. Furthermore, an adaptive capture control is disclosed that automatically adjusts the threshold level of capture control to maintain proper image capture. The invented capture control also conserves precious battery power by eliminating capture of unnecessary images when the capsule camera moves too slowly or stalls. The present invention of image capture control and threshold update is also applicable to a capsule camera system having a wireless transmitter instead of an on-board storage.

The method can include: acquiring an utterance from a user; recognizing a string of words from the utterance; acquiring for each word the ratio of actual duration of delivery to ideal duration; calculating an average ratio for all the words wherein the average ratio is an indication of the speed of the delivery of the utterance; and prompting the user as to the speed of delivery of the utterance according to the average ratio.

Traditional temperature-control products have the problem that the temperature of the working surface reaches the setting temperature too slowly when heating up or recovering from a temperature drop. A traditional temperature control circuit and temperature-settings selector components are modified to solve this problem. When heating begins, the modified circuit increases the initial setting temperature to be above the target setting temperature. The modified circuit then adjusts the setting temperature by measuring the heating power consumption. Once the working surface of the temperature control product reaches the initial setting temperature, the heating power consumption drops and the modified circuit reduces the temperature setting to the target setting temperature. The temperature control product can rapidly achieve the target temperature. A positive-temperature-coefficient heating component is used in the temperature control product.

The present invention relates to an unmanned helicopter heading compensation route transition method. During the deflection process of an unmanned helicopter, a transverse path adopts lateral zero speed maintaining control; a heading path adopts yaw angle rate maintaining control; a yaw angle rate instruction is generated according to heading deviation containing a heading compensation quantity; the heading compensation quantity is determined according to real-time side deviation, a yaw angle rate upper limit corresponding to a current flight speed and a heading compensation quantity threshold, so that a yaw angle speed instruction and a roll angle instruction are obtained; and therefore, when the unmanned helicopter rotates too quickly when swerving due to disturbance, a heading compensation mechanism enables a compensation effect for reducing the speed of rotation; and when the helicopter rotates too slowly when swerving due to disturbance, the heading compensation mechanism continuously gives out heading compensation instructions, and the helicopter continues to complete swerving until the heading deviation and side deviation of the helicopter meet requirements. The heading of the helicopter is corrected through the side deviation, so that the unmanned helicopter can accurately track a target route and achieve precise tracking and control of the route.

The invention discloses a method and a device for authenticating in a safety channel establishing process as well as an intelligent card and a terminal. The main content is as follows: when a safety module is illegally attacked (namely the continuously-appearing authentication failure times reach the pre-set lower limiting value and do not reach the upper limiting value), a manner of prolonging the time of responding message by feedback authentication is used for delaying to return an authentication failure response message to peripheral equipment, so that the peripheral equipment responds too slowly via the safety module, a problem in connection appears and the attack is stopped, or the attack is stopped as the delaying time is longer than the time delay capable of being tolerated by the peripheral equipment, so as to reduce the attack to the safety module under the condition that the safety module is not out of work, and improve the safety of the safety module.

The invention relates to a loop detection method based on a word bag model. The lexical bag model adopts binary visual features ORB with rotation invariance and scale perception. This visual feature has the same performance as SIFT feature and SURF feature and the same computational efficiency as the visual feature composed of FAST key points and BRIEF descriptor. It is a visual feature with low computational complexity and high feature salience.

This normalization method enables the system to effectively detect loops in the event that the main body moves too fast or too slowly and steers.
