An object is to improve accuracy of tightening torque and to shorten time necessary for fastening a screw in an impact type screw fastening device that uses an electric motor as a rotation driving source. A control method for the impact type screw fastening device that uses an electric motor as a rotation driving source includes the steps of driving the motor to rotate by supplying current to the motor intermittently so that torque exerted on a load by rotation of the motor becomes like pulses on the time axis, and controlling the current of every time of each pulse so that an increment of every time of each pulse of the torque after the torque reaches a target approach torque TQN that is a first set value becomes smaller than that before it reaches the target approach torque TQN.

A system and method to help maintain quality control and reduce cannibalization of accessories and attached probes in a highly sensitive patient monitor, such as a pulse oximetry system. One or more attached components may have information elements designed to designate what quality control mechanisms a patient monitor should look to find on that or another component or designate other components with which the one component may properly work. In a further embodiment, such information elements may also include data indicating the appropriate life of the component.

A computer-implemented method for targeting marketing content to an online user, includes the steps of collecting data describing the user in a user profile, comparing the user profile with a target profile and presenting the user with content based on the comparison. The user profile includes a photographic likeness of the user, as well as information derived from the user's photographic likeness. Certain content may be dynamically created for the user based on the user profile and may include the photographic likeness of the user, which may be altered to incorporate a portion of the content into the photographic likeness. In this manner, personalized advertisements for cosmetics, jewelry, clothing and other items may be created. The user profile also includes data describing the user's browsing habits and responses to context-specific survey questions. In one embodiment, metrics are assigned to the user profile data, and a data index identifying the user's preferences and purchasing habits is calculated for the user based on the assigned metrics. Each metric may also have an associated confidence factor, which causes the metric value to decay over time.

Software attacks such as worms and viruses are detected in an electronic device by monitoring power consumption patterns. In a first embodiment, software attacks are detected by an increase in power consumption. The increased power consumption can be caused by increased network traffic, or by increased activity in the microprocessor. Monitoring power consumption is particularly effective for detecting DOS / flooding attacks when the electronic device is in an idle state. In a second embodiment, a power consumption signal is converted to the frequency domain (e.g., by fast Fourier transform). The highest amplitude frequencies are identified. Specific software attacks produce characteristic frequencies in the power consumption signal. Software attacks are therefore detected by matching the highest amplitude frequencies with frequencies associated with specific worms and viruses. Identification of a particular software attack typically requires matching of 3 or more of the highest amplitude frequencies, and, optionally, amplitude information.

A drive circuit which outputs an output signal to an output terminal, includes a drive transistor configured to output a gradation current to the output terminal; a single differential amplifier; a resistance element connected with the drive transistor; and a plurality of switches. The plurality of switches are controlled such that a precharge voltage is outputted from the differential amplifier to the output terminal in a first period while blocking off an output from the drive transistor and such that a gradation current is outputted from the drive transistor to the output terminal in a second period after the first period.

In various examples, detected object data representative of locations of detected objects in a field of view may be determined. One or more clusters of the detected objects may be generated based at least in part on the locations and features of the cluster may be determined for use as inputs to a machine learning model(s). A confidence score, computed by the machine learning model(s) based at least in part on the inputs, may be received, where the confidence score may be representative of a probability that the cluster corresponds to an object depicted at least partially in the field of view. Further examples provide approaches for determining ground truth data for training object detectors, such as for determining coverage values for ground truth objects using associated shapes, and for determining soft coverage values for ground truth objects.

A multilayer electronic component includes a plurality of dielectric layers interleaved with a plurality of internal electrode elements and a plurality of internal anchor tabs. Portions of the internal electrode elements and anchor tabs are exposed along the periphery of the electronic component in one or more aligned columns. Each exposed portion is within a predetermined distance from other exposed portions in a given column such that bridged terminations may be formed by depositing one or more plated termination materials over selected of the respectively aligned columns. Internal anchor tabs may be provided and exposed in prearranged relationships with other exposed conductive portions to help nucleate metallized plating material along the periphery of a device. External anchor tabs or lands may be provided to form terminations that extend to top and / or bottom surfaces of the device. Selected of the conductive elements may be formed by a finite volume percentage of ceramic material for enhanced durability, and external lands may be thicker than internal conductive elements and / or may also be embedded in top and / or bottom component surfaces. A variety of potential internal electrode configurations are possible including ones configured for orientation-insensitive component mounting and for high density peripheral termination interdigitated capacitors.

An RFID system and method for communicating between a host computer, one or more interrogators connected to the host computer, and a large body of transponders distributed within an area covered by the interrogators. Each transponder originally has a common identification code, and upon initialization by the host computer internally generates a unique identification code based upon an internally generated random number. The host, through the interrogators, reads each of the identification codes associated with each transponder by iteratively transmitting a read identification code command along with a controlled variable. Each transponder compares the received controlled variable to an internally generated random number, and selectively transmits its identification code based upon the outcome of this comparison. After the completion of each read identification code iteration, the host adjusts the controlled variable based upon the responses received in the previous iteration. Preferably, communications between the interrogators and the transponders are DSSS signals in TDMA format, and the transponders use the random number generator to assign a time slot for transmission of their response. Each interrogator includes an antenna system utilizing a switch matrix to connect multiple antennas having different polarizations, which ensures that all transponders within the range of the interrogator receive the signals from the interrogator. In a further aspect, the interrogators are arranged in groups, each group in nearest neighbor format, to reduce the time for reading the transponders and the emissions generated when more than one interrogator is active at the same time.

A generic model structure captures basic characteristics in BIS-based patients' responses to anesthesia and surgical stimulation, the model being used in combination with the insight of an anesthesiologist. The model structure represents the patient response with a time delay, a time constant for response speed, and a nonlinear function for drug sensitivity. Clinical data confirms the model structure and is used to establish parameters and function forms for individual patients. A feedback and predictive control strategy for anesthesia drug infusion is then introduced on the basis of the patient model. Feedback control alone cannot avoid large fluctuations in BIS values when significant surgical stimulation is imposed, as a result of time delays in a patient's response to drug infusion. Predictive control attenuates fluctuations of BIS levels from surgical stimulation.

Disclosed are an improved system and a related method for compensating the chromatic dispersion of a given length of a transmission fiber over a given spectral band by employing at least two chromatic dispersion compensating fibers that, with respect to the slope of the slope of the chromatic dispersion (SSi), have values of opposite signs.
