Abstract: An RF testing method is applied between a testing instrument and multiple devices under test at least including a first DUT and a second DUT. The testing instrument includes a signal generator and a signal analyzer. A sync signal is sent to the testing instrument and the first DUT, so that the first DUT occupies the signal generator to receive a testing signal from the signal generator. The first DUT sends an uplink signal to the signal analyzer based on the testing signal to occupy the signal analyzer for signal analysis at a first point in time. The sync signal is sent to the testing instrument and the second DUT, so that the second DUT occupies the signal generator to receive the testing signal from the signal generator at a second point in time. The first point in time is parallel to the second point in time.

Abstract: A payment item having a magnetic ink character recognition (MICR)-line on its front is handled by generating, using visible light, a front image of the front of the payment item, generating, using infrared light, an infrared image of the front of the payment item or of a portion of the front of the payment item containing its MICR-line, and performing optical character recognition on the infrared image to identify data encoded in the MICR-line.

Abstract: A socket assembly includes an inner sleeve, an outer sleeve movably mounted on the inner sleeve, a space defined between the inner sleeve and the outer sleeve, and an attachment device mounted in the inner sleeve. Thus, the screwdriver head is locked by the locking member elastically, so that the screwdriver head can be mounted on and detached from the inner sleeve easily and conveniently, thereby facilitating the user mounting and removing the screwdriver head.

Abstract: A method and system is disclosed for facilitating the input of information into a computing device by a scanning means. A pocket scanner that has only the minimum components/parts therein and will not operate without being connected to the computing device that subsequently receives scanning signals therefrom. In particular, the disclosed scanner does not have a separate power supply to energize the components/parts to work.

Abstract: A pre-boot security controller in an electronic device is energized even though a power subsystem does not energize operation of a digital computer in the device. The security controller stores supervisor and user passwords in a non-volatile password memory for comparison with a password entered using a security keypad. While the security controller is in a security operating mode, an output signal from the securing controller indicates the existence of that operating mode. Upon entry of a matching password, the security controller enables the power subsystem to energize operation of the digital computer, disables the output signal that indicates the existence of the security operating mode, and the security controller transitions from the security to an application operating mode. In the application operating mode, the pre-boot security controller preserves data about pressings of the security keypad.

Abstract: A method and apparatus for reducing power consumption by a display device includes monitoring time intervals between successive updates by video update circuitry and time intervals between successive uses by one or more user-interface devices, such as a mouse or keyboard. A first time-elapsed signal is generated if a predetermined time interval is exceeded between successive uses by the user-interface devices. A reset input to a first timer is connected to the user-interface devices to restart the timing with each use. A second time-elapsed signal is generated if the interval between successive video updates exceeds a second predetermined time period. Video updating resets the timer used to monitor the video update circuitry, but once the second time-elapsed signal has been initiated, a video update will not disable the signal. Rather, the second time-elapsed signal is latched until the use of a user-interface device.
