| 20090309879 | Statistically-based Display Processing - In exemplary embodiments, a waveform processor system may update pixel state information as a function of current pixel state information (e.g., intensity, color) by comparing a randomized value to a set of predetermined threshold values that correspond to different permitted pixel states. In an illustrative example, each time a display screen is updated, the image may represent multiple (e.g., 2000) triggered sweeps of the waveform. For each triggered sweep, the waveform data is associated with specific pixels on the display screen. To determine how to update each pixel's state (e.g., brightness, color) for the next screen update, each waveform hit on a pixel may initiate a comparison between a randomized value (e.g., pseudorandom number) and the predetermined threshold value for the pixel's current pixel state. In some examples, the pixel state may be increased to the next level if the randomized value exceeds the predetermined threshold value. | 12-17-2009 |

| 20100053169 | SYSTEM AND METHOD FOR COMMUNICATION BETWEEN MOBILE DEVICES USING DIGITAL/ACOUSTIC TECHNIQUES - Techniques have been developed for transmitting and receiving information conveyed through the air from one portable device to another as a generally unperceivable coding within an otherwise recognizable acoustic signal. For example, in some embodiments in accordance with the present invention(s), information is acoustically communicated from a first handheld device toward a second by encoding the information in a signal that, when converted into acoustic energy at an acoustic transducer of the first handheld device, is characterized in that the acoustic energy is discernable to a human ear yet the encoding of the information therein is generally not perceivable by the human. The acoustic energy is transmitted from the acoustic transducer of the first handheld device toward the second handheld device across an air gap that constitutes a substantially entirety of the distance between the devices. Acoustic energy received at the second handheld device may then be processed using signal processing techniques tailored to detection of the particular information encodings employed. | 03-04-2010 |

| 20100066743 | Method for improved visualization of dynamic values displayed in a digital format - A method is provided for improved visualization of digitally displayed values that change rapidly, based on the human ability to perceive only a certain amount of change within a specific time-frame. The changes to the value are displayed so that, whenever possible, only one digit changes within the time-frame thought to be ideal for a user to perceive the change of a single digit. The actual value displayed will follow the true value as closely as possible, hence, in most cases, only the digit that moves the displayed value closest to the true value will trigger a change during a perception time frame. If the true value stops changing, the displayed value will, by this fashion, completely catch up with the true value in a prompt manner and exactly match it. If the true value oscillates rapidly, the oscillation will only be displayed to the extent that it allows the viewer to perceive the changes. Only the amount of change that can be perceived is actually shown, thus greatly improving the readability of digital displays. | 03-18-2010 |
| 20100066742 | STYLIZED PROSODY FOR SPEECH SYNTHESIS-BASED APPLICATIONS - Described is a technology by which the prosody of synthesized speech may be changed by varying data associated with that speech. An interface displays a visual representation of synthesized speech as one or more waveforms, along with the corresponding text from which the speech was synthesized. The user may interact with the visual representation to change data corresponding to the prosody, e.g., to change duration, pitch and/or loudness data, with respect to a part (or all) of the speech. The part of the speech that may be varied may comprise a phoneme, a morpheme, a syllable, a word, a phrase, and/or a sentence. The changed speech can be played back to hear the change in prosody resulting from the interactive changes. The user can also change the text and hear/see newly synthesized speech, which may then be similarly edited to change data that corresponds to that speech's prosody. | 03-18-2010 |

| 20120236003 | Real-Time Visualization of Data Through a Bottleneck - Transferring a dataset larger than the packet size requires may require that the data be split over multiple transfers.
