Abstract: A method for evaluating bit error rate for a magnetic head by using a quasi-static test system, includes step (a), measuring a noise characteristic curve for a magnetic head, and the noise characteristic comprising noise amplitude and maximum noise amplitude; step (b), constructing a noise waveform by appropriately scaling a signal noise ratio of the magnetic head based on the noise characteristic curve measured in step (a); and step (c), injecting the noise waveform constructed in step (b) into a model comprising a transmitter module and a receiver module to evaluate a bit error rate. The method saves testing time, reduces manpower, and obtains accuracy testing result.

Abstract: The invention relates to a method and a system (SYS) for managing an alarm signal in a system comprising a first internal clock. The system is intended to cooperate with a portable player (PP) comprising a second internal clock and a screen (S). The method comprises the steps of: —setting the time of said first internal clock at the time of said second internal clock, —selecting a given time value being displayed on said screen, —memorizing said given time value in said system, —setting the time of said second internal clock at the time of said first internal clock, —triggering an alarm signal on said system when the time of said first internal clock reaches said given time value. According to this method, when the portable player is docked to the system, the system according to the invention does not require its own screen because the screen of the portable player is used to display the current time and the alarm time during setting it, resulting in a reduction of the costs of the system.

Abstract: A screw installation device is provided, including a base having a tray for carrying a circuit board, a vertical holder vertically disposed on the base, an accommodating unit, an elastic unit, and a double-link horizontal holder having one end connected to the vertical holder and the other end connected to the accommodating unit for accommodating an electric screwdriver. The double-link horizontal holder adjusts the position of the accommodating unit such that the electric screwdriver is movable with respect to the tray in both vertical and horizontal directions. The elastic unit is mounted on the double-link horizontal holder for providing the accommodating unit with an upward elastic force after a downward force is exerted on the electric screwdriver for installing the screw. The present invention eliminates the adverse effects such as reduction in service life and scratching of the product as a result of slippage of the electric screwdriver head.

Abstract: A back case for use with a portable electronic device has a connection element for electrical connection with the portable electronic device. The back case is characterized in that the back case has a back cover and a sidewall; the back case has a receiving space; the back cover has a plurality of holes; the holes are positioned proximate to an end side of the back cover; the portable electronic device is received in the receiving space provided by the back case; the holes provides a resilient deformation force for the back case, so as for the portable electronic device to be fixed in place by the sidewall. Due to the holes of the back case, the back case can be mounted on or dismounted from the portable electronic device easily.

Abstract: A mobile switching center is configured with software instructions which allow it to continue to provide at least limited call termination and call origination services for mobile terminals in the event of a failure of a signaling link between the mobile switching center and a home location register and/or a signal control point (SCP) in an intelligent network. For pre-paid callers originating or terminating a call, the mobile switching center marks a call detail record as indicating that the call is a post-paid call. The call detail record is later provided to the SCP after the signaling link has been restored in order to bill the mobile terminal. In one example, the signaling link between the mobile switching center and the home location register or SCP may be a satellite link, which may go down for various reasons such as for maintenances, an unexpected failure, or the orbit of the satellite goes outside the field of reception of an antenna in the signal path.

Abstract: A method for detecting a watermark signal in digital image data. The detecting method includes the steps of: computing a log-polar Fourier transform of the image data to obtain a log-polar Fourier spectrum; projecting the log-polar Fourier spectrum down to a lower dimensional space to obtain an extracted signal; comparing the extracted signal to a target watermark signal; and declaring the presence or absence of the target watermark signal in the image data based on the comparison. Also provided is a method for inserting a watermark signal in digital image data to obtain a watermarked image.
