The blackout rules may restrict IP addresses, IP address subnets, or geographic regions defined using zip codes or DMAs. The first identifier can be an IP address that directly or indirectly maps to the blackout rules. If the first identifier is restricted by a blackout rule, the server identifies the restrictions of the rule, when they apply, and how they are to be applied before dynamically altering the content that is streamed to the end user device.

Multitree subdivision and inheritance of coding parameters in a coding block
A better compromise between encoding complexity and achievable rate distortion ratio, and/or to achieve a better rate distortion ratio is achieved by using multitree sub-divisioning not only in order to subdivide a continuous area, namely the sample array, into leaf regions, but using the intermediate regions also to share coding parameters among the corresponding collocated leaf blocks. By this measure, coding procedures performed in tiles—leaf regions—locally, may be associated with coding parameters individually without having to, however, explicitly transmit the whole coding parameters for each leaf region separately. Rather, similarities may effectively exploited by using the multitree subdivision.

An N-port, shared-memory switch allocates a shared headroom buffer pool (Ps) for a priority group (PG). Ps is smaller than a worst case headroom buffer pool (Pw), where Pw equals the sum of worst case headrooms corresponding to each port-priority tuple (PPT) associated with the PG. Each worst case headroom comprises headroom required to buffer worst case, post-pause, traffic received on that PPT. Subject to a PPT maximum, each PPT may consume Ps as needed. Because rarely will all PPTs simultaneously experience worst case traffic, Ps may be significantly smaller than Pw, e.g., Ps<(Pw/A) where M>=2. Ps may be size-adjusted based on utilization of Ps, without halting traffic to or from the switch. If Ps utilization exceeds an upper utilization threshold, Ps may be increased, subject to a maximum threshold (Pmax). Conversely, if utilization falls below a lower utilization threshold, Ps may be decreased.

Optically-induced charge separation and induced magnetism in dielectrics for optical energy conversion and intense magnetic field generation
Schemes are described to produce quasi-static charge separation, Terahertz radiation, and programmable magnetic field generation using linearly-polarized light in unbiased, transparent insulators. The methods exploit a recently-observed magneto-electric optical nonlinearity that produces intense magnetization in undoped, homogeneous dielectrics. Analysis reveals that strong magnetic effects can be induced at modest optical intensities even with incoherent light. Consequently, efficient solar power conversion is feasible without the semiconductor processing or electron-hole pair generation that is required in conventional photovoltaic cells. Additionally, conditions and techniques are described to generate intense THz radiation in unbiased substrates and large magnetic fields orientated transverse to the direction of propagation of light, without the need for any external permanent magnetic or electromagnetic apparatus.

Method for providing a magnetic recording write apparatus having a seamless pole
A method provides a magnetic write apparatus. The method includes providing a pole including a pole tip, a yoke, a pole bottom and a pole top. The pole is seam free and formed vertically in a direction from the pole bottom toward the pole top. At least one coil for energizing the pole is also provided. In some aspects, providing the pole may include removing a portion of an intermediate layer to form a trench therein. The trench has a shape and location corresponding to the pole, a bottom, a top and sides. A conductive layer is deposited in the trench and on a top surface of the intermediate layer. Insulating layer(s) are provided on the sides of the trench. Only part of the conductive layer on the trench bottom is exposed. Pole material(s) are grown on the exposed portion of the conductive layer to provide the pole.
Apparatus and method for generating bandwith extension signal
An apparatus for generating a bandwidth extended signal includes an anti-sparseness processing unit to perform anti-sparseness processing on a low-frequency spectrum; and a frequency domain high-frequency extension decoding unit to perform high-frequency extension encoding in the frequency domain on the low-frequency spectrum on which the anti-sparseness processing is performed.
Apparatus and method of reducing noise and audio playing apparatus with non-magnet speaker
An audio apparatus is provided. The audio apparatus includes an input configured to receive an audio signal containing noise; a period estimation unit configured to estimate a period of a noise pattern in the audio signal; a noise reducer configured to subtract and remove the noise pattern from the audio signal in a frequency domain by using the estimated period of the noise pattern; a noise updater configured to update the noise pattern according to a change in amplitude of the noise; and an output configured to output the audio signal obtained by removing the noise pattern.
Analysis of long-term audio recordings
Techniques for analyzing long-term audio recordings are provided. In one embodiment, a computing device can record audio captured from an environment of a user on a long-term basis (e.g., on the order of weeks, months, or years). The computing device can store the recorded audio on a local or remote storage device. The computing device can then analyze the recorded audio based one or more predefined rules and can enable one or more actions based on that analysis.
Apparatus and methods for a collapsible stand for a stringed instrument
A collapsible and height adjustable stand for a stringed musical instrument is described; specifically, a compact, portable and customizable stand for holding stringed instruments in a secure upright position. The stand can be easily used and also collapsed back quickly after use. Padding on the top and bottom cradle handles holds the instrument and cushions the stringed instruments. Also, a bow hook attached to the upper part of the stand allows for hanging the bow. The adjustable height feature allows the stand to hold musical stringed instruments of different sizes.
Hammer velocity measurement system
A system 100, for determining the velocity of a hammer 120 of a keyboard instrument, with a light transceiver 140 and processing circuitry 160. The light transceiver 140 being configured to transmit a light signal to a hammer 120 to measure a hammer velocity, receive a reflected light signal from the hammer 120 indicative of the velocity of the hammer 120 and send an electrical signal to the processing circuitry 160, where the electrical signal is based on the reflected light signal from the hammer 120. The processing circuitry 160 being configured to receive and process the electrical signal so that a time interval between the electrical signal passing through a first trigger point and a second trigger point and the velocity of the hammer 120 can be determined.
System and method for displaying layered images
A system and method for displaying layered images is provided. A rear display element displays a first image including a background. A transmissive display element displays a third image and a fourth image, the third image being displayed contemporaneously with the first image. The transmissive display element has a front surface and a rear surface. The rear surface is placed a predetermined distance from the rear display element such that images displayed by the rear display element and by the transmissive display element can be viewable through the front surface of the transmissive display element. A lighting element provides backlight illumination to the transmissive display element contemporaneously with the fourth image. The lighting element can provide the backlight illumination by having the system display a second image at the rear display element for transmitting a backlight illumination from the rear display element contemporaneously with the fourth image.
