Abstract:
A Wi-Fi ATSC TV Antenna with Waveform Compression is comprised of 5 components—TV antenna, ATSC TV tuner, AD Converter, Waveform Data Compression Unit, and Wi-Fi Transceiver. It is used to transfer Analog RF Waveform to Digital IF Signal over Wi-Fi to a TV-viewing device. It is used for ATSC TV reception devices.
Abstract:
This invention is a method to quickly characterize the time variant channel state information to enable ATSC HDTV signal reception in a mobile environment (e.g. in a moving car, walking, on a bus, etc.) by removing the Doppler interference. The invention relates to a single or multiple antenna ATSC terrestrial DTV receiver for indoor and mobile users.
Abstract:
The present invention provides methods of achieving directed evolution of viruses by in vivo screening or “panning” to identify viruses comprising scrambled AAV capsids having characteristics of interest, e.g., tropism profile and/or neutralization profile (e.g., ability to evade neutralizing antibodies). The invention also provides scrambled AAV capsids and virus particles comprising the same.
Abstract:
Systems, methods, and devices for wireless communication. In one aspect, an apparatus for wireless communication is provided. The apparatus includes a receiver configured to receive a wireless signal comprising a packet. At least a portion of the wireless signal is configured to be received over a bandwidth lower than or equal to 1.25 MHz. The packet is formed from at least one orthogonal frequency-division multiplexing (OFDM) symbol comprising thirty-two tones. The thirty-two tones correspond to frequency subcarriers within the bandwidth. The thirty-two tones of the at least one OFDM symbol are allocated as: twenty-four data tones, two pilot tones, five guard tones, and one direct current (DC) tone. The apparatus includes a processor configured to evaluate the wireless signal. The processor includes a transform module configured to convert the at least one OFDM symbol into a frequency domain signal using a thirty-two point mode.
Abstract:
Methods, apparatuses, and computer program products are disclosed for facilitating decoding a communication received from a wireless terminal. Encoded bits are received from the wireless terminal via a shared uplink channel, and a plurality of acknowledgment tones are identified within the encoded bits. A correlation value is ascertained corresponding to a correlation between detected bits within the plurality of acknowledgment tones and valid bits corresponding to any of a plurality of valid acknowledgment codewords. A determination is then made as to whether the plurality of acknowledgment tones includes information corresponding to a discontinuous transmission by comparing the correlation value to a threshold value.
Abstract:
An apparatus includes an interleaver configured to interleave encoded data and to output a series of interleaved bits to be transmitted via a 1 MHz orthogonal frequency-division multiplexing (OFDM) transmission. The apparatus also includes a modulator configured to modulate the interleaved bits and a transform module configured to transform the modulated bits. A transmit module of the apparatus is configured to transmit the transformed bits included in one or more spatial streams of the 1 MHz OFDM transmission.
Abstract:
An example includes a method of imaging brain activity. The method includes receiving signals corresponding to neuronal activity of the brain. The signals are based on a plurality of scalp sensors (110). The method also includes decomposing the signals into spatial and temporal independent components (140). In addition, the method includes localizing a plurality of sources corresponding to the independent components. The method includes generating a spatio-temporal representation of neural activity based on the plurality of sources.
Abstract:
An emergency exit indicator includes a flat housing and a light source received in the housing. The housing has a length greater than a width thereof. The housing includes a panel provided with a sign thereon to indicate emergency exit. The light source includes a plurality of LEDs each being covered by a lens. Light of the LED goes through the lens and is then illuminated on the sign to cause the sign to be visible. The lens has two opposite sides along a lengthwise direction of the housing longer than other two opposite sides along a widthwise direction of the housing, such that the light through the lens along the widthwise direction of the housing is converged in a narrower manner than the light through the lens along the lengthwise direction of the housing.
Abstract:
A preservative system and a personal care composition containing that system is provided which includes the preservative combination of a C10C24 acyl glycinate salt and a dihydroxypropyl quaternary ammonium salt, and wherein the system exhibits a Log Reduction against Pseudomonas aeruginosa of at least 2 within 48 hours of application to an aqueous system. This preservative system is effective against gram negative bacteria, particularly Pseudomonas aeruginosa.
