  • Patent number: 9218486
    Abstract: When using intrusion detection systems, security specialists are concerned with false positive rates and true positive rates. False positives are when an alert is raised, but no actual intrusion occurs. True positives are when an alert is raised for an actual intrusion. Ideally, true positive rate is 1 and false positive rate is zero, but such a situation is impossible in the real world. So one must balance a true positive rate and a false positive rate to produce the best result at the best price. One can simplify the choice of detection sets by, instead of determining each possible operating point of the information detection system, by only choosing operating points that are not dominated by other operating points.

If so, the number or duration of the partial sequences is modified, and a check using the computer model is again implemented. A number or respective duration of the partial sequences that results in the load limit not being exceeded is then used as a final output in order to operate the medical imaging system.

Otherwise, the device acquires a second parameter value of the hardware component that follows the first parameter value, and calculates a second prediction value of the second parameter value. If a difference between the second prediction value and the second parameter value falls with a second deviation range, the first parameter value is determined as a real value and is stored. Otherwise, the first parameter value is determined as a false value and is abandoned.

  • Publication number: 20130304410
    Abstract: In a method for testing sensors of a server, the method obtains serial numbers of each of the sensors from a board management controller (BMC) of the server using an intelligent platform management interface (IPMI) service of the server, and modifies lower and upper critical values to generate first and second system event logs even during normal working of the components subject to sensing. The method records a confirmed and tested status of each of the sensors if the first system event log and the second system log are right.

  • Patent number: 8577629
    Abstract: A method and system related to phased array ultrasonic systems identifies faults in individual element on a regular basis. The method and system are based on a simple approach of calculating energy levels in response signals from each individual element and then identifying any discontinuities or unexpected drops in energy levels sensed during a typical phased array operation, by comparing responses for individual transducer elements to the group response.

  • Patent number: 8563909
    Abstract: An apparatus and method improves the fault tolerance of a rocket or missile guidance system which includes a resonant sensor. When improper initialization is detected, the resonant sensor is reinitialized, repeatedly if necessary, until normal operation is achieved. Improper initialization is detected by comparing data from the guidance system with pre-specified physical limits to roll, pitch, yaw, and/or other features of the flight scenario. Embodiments can also detect a fault condition due to an error signal from a “Built-in-Test” (BIT) module. The initialization sequence initiated by the invention can be identical to the power-on sequence, or it can be a separate, reinitiating sequence. Subsequent resets are initiated as needed, for example until the burn of the rocket fuel and the associated vibrations have ceased and the resonant sensor has been successfully initialized.

  • Patent number: 8560261
    Abstract: A sensor fixture can be affixed within a wall and powered using the same cable along which data signals are transmitted. A data cable is attached to the fixture, and power for a sensor is isolated from the data signals. The sensor may be used in conjunction with a building automation system in order to provide environmental inputs, such as from a motion sensor, a light sensor, and an audio sensor. The sensor may also be combined with LED lights for a combined fixture that lights when sensing motion or other environmental changes, for example.

  • Patent number: 8537036
    Abstract: A device for transferring keyboard commands from a user to an electronic apparatus or machine. An arm intended to be carried by the user as a headset, is provided with signal sensors responding to the presence or pressure of the user's tongue by emitting an electric signal or impulse. A signal unit registers and converts signals from the sensors into corresponding keyboard commands which are then input to the electronic device or machine. The device thus basically works as a keyboard where the signal sensors constitute keys that can be operated solely by the tongue, i.e. without involving the hands.
