    Abstract: A system and method for emulating a USB peripheral device is disclosed. The system utilizes a USB programming and operating interface to interact with the host but formats the data into a format usable by a non-USB peripheral device. Such a system consumes less real estate and power than a USB interface controller and USB peripheral, but remains compatible with software designed to interact with those USB devices.

    Abstract: A system having a pair of input signals, one of which is modulated and transformed into a pair of signals phased 180.degree. apart. These signals are acted on by a FET correlator where the second input signal controls the FET gate. Correlator output is amplified and a blocking capacitor removes DC offset, a synchronous switch operated at the modulated frequency converts the remaining AC to DC which is amplified to the output.

    Abstract: A method and apparatus for the spectrochemical analysis of a sample in which a solid state array detector (82) is used to detect radiation (62) of spectrochemical interest. The invention involves the use of a shutter (72) adjacent the entrance aperture (70) of a polychromator (74-80) to expose the detector (82) to the radiation (62) for varying lengths of time whereby for short duration exposure times charge accumulation in elements (i.e. pixels) of the detector (82) due to high intensity components of the radiation is limited and for longer exposure times charge accumulation in elements (pixels) of the detector (82) due to feeble intesity components of radiation (62) is increased. This ensures that each reading of the detector (82) includes at least one exposure in which the amount of charge accumulated at each wavelength of interest is neither too little or too great. The problems of feeble radiation components not being accurately measurable and of high intensity radiation components exceeding the charge carrying capacity of elements (pixels) of the detector (82) are thereby able to be avoided. An attenuator (90) may be placed between the radiation source (60) and the detector (82) to permit longer exposure times to be used for very high intensity radiation.

    Abstract: Methods and apparatuses whereby legally obtained media files are marked so they are associated with the legal owner. A legally obtained media file is delivered normally, without any form of interruption. However, when an illegally obtained media file is delivered, a message file is delivered in association with the media file.According to an embodiment, a method of the invention comprises receiving a media file, retrieving an identifier that uniquely identifies a player unit, appending the identifier onto the media file, and storing the appended media file in a data storage medium.According to another embodiment, a method of the invention comprises receiving a media file with a first identifier, retrieving a second identifier, comparing the first identifier with the second identifier, retrieving a message file from a non-volatile memory and producing a message output if the first identifier does not correspond to the second identifier, and producing a media output from the media file.
