Abstract: Ancillary service capability data is received in real time from participating electrical vehicles (EVs) connected through EV charging equipment to a power grid. Aggregate offers based on the ancillary service capability data from participating EVs are generated and matched with requests received from electrical power generating entities for ancillary service electrical power. Associated with the matches, ancillary power is transferred from batteries of one or more EV batteries to the power grid and, based on received transaction parameters, transaction payment is made.

Abstract: Providing for management of a dynamic mobile coupon (DMC) at a mobile device is described herein. Particularly, dynamic characteristics associated with the DMC, such as a redeemable value, can be utilized to browse, sort, search, recall, or redeem the DMC utilizing a user interface of the mobile device. In other aspects, a DMC management application can interact with server components to backup and store DMC data, synchronize dynamic information (e.g., a dynamic redeemable value), access or manage a user profile, interface with other mobile devices to accomplish sharing, trading, exchanging, selling the DMC, and so on. Accordingly, provided is an efficient and personable way to manage mobile coupons in a mobile operating environment and provide increased value and utility for a user of such coupons.

Abstract: Providing for distribution of a dynamic mobile coupon (DMC) based on verified peer-to-peer (P-P) ranging between two wireless devices is described herein. By way of example, a first device can form a wireless link with a mobile device and initiate P-P ranging. By analyzing signals sent over the wireless link, a distance between such devices can be determined. In addition, at least a minimum distance between such devices can be verified based on actions performed by the mobile device that require a minimum completion time. Based in part on this verified distance, a DMC can be issued to the mobile device. Accordingly, the subject disclosure provides for increased security for issuing the DMC and mitigation of device spoofing, by verifying a minimum distance to the mobile devices and conditioning issuance of the DMC on such verified distance.

Abstract: Dynamic mobile coupons (DMCs) having a variable commercial value and/or other variable coupon characteristic are provided herein. By way of example, a DMC can be distributed to a mobile device based on criteria established by a sponsor of the DMC. A redemption value of the DMC can be variable and dynamically established based at least in part on data associated with a recipient mobile device. Upon redemption of the DMC at a retail entity, the value is fixed and applied to a transaction. Details of the transaction are provided to a remote clearinghouse that performs mediation and indemnification functions to finalize the transaction. As described, the subject disclosure provides a DMC that facilitates a rich and flexible mechanism to generate purchasing incentive for consumers in a mobile environment.

Abstract: Processing may be performed by a first device on behalf of a second device to offload processing from the second device. In some aspects a device from which processing has been offloaded may be advantageously adapted to consume less power, have a smaller size, and have less complexity. Offloaded processing may be employed to enable a first device to process data for transmission and then send the data to another device for processing. Offloaded processing may be employed to enable a first device to process data on behalf of a second device and then send the processed data to the second device. In some aspects the data may be waveform encoded for wireless transmission between the devices. Offloaded processing may be implemented in a static manner or in a dynamic manner.

Abstract: Various operations may be performed based on distance-related functions associated with two or more devices. For example, one or more distance-based functions may be used to control whether a device is allowed to request another device to perform one or more functions. Similarly, one or more distance-based functions may be used to control whether a device may perform one or more functions requested by another device. A distance-related function may take various form including, for example, a distance between devices, two or more distances between devices, a rate of change in a relative distance between devices, relative acceleration between devices, or some combination of two or more of the these distance-related functions.

Abstract: A system (300, 500) for scrambling digital samples (115, 200, 250, 260, 270) of multimedia data, including audio and video data samples, such that the content of the samples is degraded but still recognizable, or otherwise provided at a desired quality level. The samples may be in any conceivable compressed or uncompressed digital format, including Pulse Code Modulation (PCM) samples, samples in floating point representation, samples in companding schemes (e.g., ?-law and A-law), and other compressed bit streams. The quality level may be associated with a particular signal to noise ratio, or quality level that is determined by objective and/or subjective tests, for example. A number of LSBs can be scrambled in successive samples in successive frames (FRAME A, FRAME B, FRAME C). Moreover, the parameters for scrambling may change from frame to frame. Furthermore, all or part of the scrambling key (310) can be embedded (340) in the scrambled data and recovered at a decoder (400, 600) to be used in descrambling.

Abstract: A system for measuring exposure to a visual display such as a billboard. A transmitter that is proximate to the billboard broadcasts a data signal that carries information relating to the billboard. This information may identify the location of the billboard, the message displayed by the billboard, and time of day. The data signal is provided at a power level that is adapted to reach a pre-defined exposure area in which the billboard can be viewed. A portable receiving device is provided to a defined consumer population to measure the exposure of the consumers to the billboards. The receiving device may be carried or worn by the consumer, or carried in the consumer's vehicle. The receiving device is adapted to recover the data signal and store the information relating to the billboard when the viewer is in the pre-defined exposure area. The time of day and duration of the exposure may also be recorded.

Abstract: Auxiliary data is transported in subbands of a primary data signal by hiding the data in the form of colored noise. The colored noise has a spectrum that simulates the spectrum of the primary data signal in each subband. The data to be transported is first converted to a spread spectrum signal. The primary data signal is analyzed to determine its spectral shape. The same spectral shape is imparted to the spread spectrum signal in each subband, which is then combined with the primary data signal for transmission. The spectral shaping can be performed using time domain modeling and synthesis such as linear predictive coding. A plurality of different auxiliary information streams can be transported on the primary data signal. By adjusting the gain of individual spread spectrum signal carrier(s) and the power of the colored noise, the auxiliary information stream(s) can be rendered at any desired level below or above an interference threshold in the primary data signal.

Abstract: Reproduction of a multi-media data signal which is stored on a source media or distributed via a communication network is controlled by inserting master tag data and control tag data into the data signal. A player/recorder inserts an additional generation of control tag information each time a copy of the media is made. If the number of generations of the control tag information is above a threshold value, reproduction of the data signal may be inhibited. For example, if the data signal comprises video data, the player/recorder may only allow playing of the video signal on a display but will not allow recording. The playing and recording of associated signals, such as an audio signal which accompanies a video signal, may also be controlled. The master tag data and control tag data may be provided as spread spectrum signals which are spectrally shaped and power-adjusted according to the data signal to render them imperceptible in the data signal.

Abstract: Auxiliary data is carried substantially imperceptibly with video transform data in combined transform samples according to a visibility threshold. The auxiliary data provides a capability for a copy protect scheme or verification of television viewing activity. The video transform samples are extracted from a compressed packetized data stream and normalized if required. The auxiliary data modulates data carrier sequences such as pseudo-noise (PN) spread spectrum signals in different spatial frequencies to provide auxiliary data subband samples, which are in turn combined with the video transform samples in one or more spatial frequencies to provide combined subband samples. The auxiliary data subband samples may be also spectrally shaped according to the video transform samples to improve concealment. The combined transform samples are then multiplexed into the packetized data stream. Full decompression of the video transform samples is not required.

Abstract: Auxiliary data is transported in a conventional audio signal by hiding the data in the form of colored noise. The colored noise has a spectrum that simulates the spectrum of the primary audio signal. The data to be transported is first converted to a spread spectrum signal. The primary audio signal is analyzed to determine its spectral shape. The same spectral shape is imparted to the spread spectrum signal, which is then combined with the primary audio signal for transmission. The spectral shaping can be performed using time domain modeling and synthesis such as linear predictive coding or by using subband coding techniques such as fast Fourier transforms. A plurality of different auxiliary information streams can be transported on the audio signal. By adjusting the gain of individual spread spectrum signal carrier(s) and the power of the colored noise, the auxiliary information stream(s) can be rendered inaudible in the primary audio signal, or at any desired level below or above an audible threshold.

Abstract: Reproduction of a data signal which is stored on a source media or distributed via a communication network is controlled by inserting master tag data and control tag data into the data signal. A player/recorder inserts an additional generation of control tag information each time a copy of the media is made. If the number of generations of the control tag information is above a threshold value, reproduction of the data signal may be inhibited. For example, if the data signal comprises audio data, the player/recorder may only allow playing of the audio signal over speakers but will not allow recording. The playing and recording of associated signals, such as a video signal which accompanies an audio signal, may also be controlled. The master tag data and control tag data may be provided as spread spectrum signals which are spectrally shaped and power-adjusted according to the data signal to render them imperceptible in the data signal.

Abstract: Auxiliary data subband samples representing an auxiliary data signal are transported in a subband-coded compressed digital audio signal without decompressing the data. A pre-existing packetized data stream is provided to an input of a encoder. Subband audio samples are extracted from the packet stream and normalized if required. The data to be transported modulates data carrier subbands including, for example, a pseudo-noise (PN) spread spectrum signal, each subband of which has a bandwidth corresponding to those of the digital audio signal. The data carrier sequence can also include a sparse PN sequence, sample twiddle sequence, or a bit twiddle sequence. The modulated data carrier sequence is combined with the audio subband samples to form a combined signal in which the auxiliary data subband samples are carried. The combined signal is then multiplexed into the pre-existing packet stream. In a decoder, the combined signal is demodulated to recover the auxiliary data signal.
