摘要： An electronic keyboard instrument is provided and methods of playing and assembling the same. The instrument comprises a controller for enabling activation of electronic signals having audible, visible, amplifiable, recordable and/or like characteristics, and a power source for operating the controller. A first keyboard is provided having a first selected length and being oriented in a first direction such that (i) audible notes of music from at least one internal sound module and/or at least one external sound module, (ii) recordable data to be enhanced or modified by an external sequencer or program controlled apparatus, (iii) photoelectric signals, and (iv) processes or mechanisms, triggered or controlled by external signals or data, for controlling machines, video playback or lighting, and/or the like may be generated and/or activated using a first hand of one or more users. A second keyboard with a second selected length is generally coextensive with and oriented generally opposite to the first such that (i) audible notes of music from at least one internal sound module and/or at least one external sound module, (ii) recordable data to be enhanced or modified by an external sequencer or program controlled apparatus, (iii) photoelectric signals, and (iv) processes or mechanisms, triggered or controlled by external signals or data, for controlling machines, video playback or lighting, and/or the like may be generated and/or activated using a second hand of the one or more users. In addition, an interface connects the controller to at least one external device having sound module, and/or sequencing and signal enhancement functions. A plurality of peripheral devices operatively connected thereto permit interactive control and manipulation of the signals. Finally, a wearable support is mounted to the instrument for suspending the first and second keyboards from the user's body during instrument operation. Alternatively, the instrument is suspended by a support structure in a generally horizontal fashion for simultaneous operation by multiple users.

摘要： Methods and apparatuses are provided for depositing a material on a surface. In accordance with the method a stream of a component material is formed having formed printing and non-printing droplets and satellite droplets of the material. The stream is directed at the surface. A deflecting energy is applied to separate printing droplets from non-printing droplets in the stream, so that only printing droplets travel to the surface. The deflecting energy is adapted to direct non-printing droplets for non-printing drop collection, and to direct at least a portion of the satellite droplets to be controlled in a manner adapted to prevent the material in the satellite droplets from reaching the surface, so that less than all of the material in the satellite droplets reaches the surface. Articles are also provided having limited satellite material.

In another implementation, a digital watermark detector is providing including: electronic processing circuitry; memory; and executable instructions stored in memory for execution by said electronic processing circuitry. The instructions comprises instructions to: process a media signal comprising a digital watermark redundantly embedded therein; select a subset of the media signal for watermark detection, wherein the subset of the media signal is selected based on at least one media signal characteristic associated with the subset; and detect a digital watermark hidden in the subset of the media signal.

摘要： This disclosure describes methods for using embedded auxiliary signals in documents for copy detection. In one implementation we embed an auxiliary signal with a first color that is out of gamut with process color inks or with a particular range of printers. A process color approximation of the first color yields a relatively different contrast when, e.g., viewed with an interference filter. A copy is determined based on the relative presence or absence of the auxiliary signal. In another implementation, we provide a first auxiliary signal with a first color and a second auxiliary signal with a second color. A filter is matched according to the spectral response of the first color. The second color preferably includes a spectral response that is inversely related to the matched filter. The first signal is then detectable in a process color copy, but less so in the original. However, the second signal is detectable in the original, but less so in the copy. In still other implementations we compare relative contrast of a signal to determine an original from a copy.

摘要： The disclosure describes a method of progressively decoding a digital watermark on a distributed computing platform. A client device equipped with a digital camera, such as a PDA or cell phone, captures a digital image of a watermarked object, and pre-filters the image to isolate a portion of the image data suspected of containing a digital watermark. The pre-filter de-correlates a portion of the image data suspected of containing a digital watermark from the remaining host image signal using a predictive filter. The client then quantizes the filtered data and progressively transmits the quantized data to a watermark decoder. The progressive transmitter sends image data as necessary to achieve a valid decoding operation. To reduce bandwidth requirements, the transmitter starts with the most highly quantized version of the filtered image, and sends lesser quantized versions until the watermark decoder completes a successful decoding operation.
