Abstract:
Certain aspects of the present disclosure relate to a technique for constructing a short training field (STF) sequence of a Very High Throughput (VHT) preamble in an effort to reduce a peak-to-average power ratio (PAPR). The constructed STF sequence may feature a specific repetition period.
Abstract:
A server chassis having a low-profile characteristic is disclosed to include a chassis shell, which defines an accommodation chamber that accommodates an electronic device and a motherboard, a fan module located on one open side of the accommodation chamber in the chassis shell and defining a mounting space in the accommodation chamber, and a connector module, which includes a housing movable in and out of the mounting space inside the chassis shell and locked to the chassis shell with screws, a plurality of peripheral apparatuses carried in the housing of the connector module and an adapter board mounted on the rear side of the housing for the connection of the electronic device, the electric fans and the peripheral apparatuses.
Abstract:
A device is provided. the device comprises A device comprising: a Frequency Domain Maximum Ratio Combining Decision Feedback Equalizer (FD-MRC-DFE), a first device down stream to the FD-MRC-DFE; a second device down stream to the FD-MRC-DFE; and a third device for averaging the outputs of the first device and the second device.
Abstract:
A battery connector has an insulating housing, a plurality of terminals mounted to the insulating housing, and a supporting member fixing the insulating housing on the PCB. The insulating housing has a rectangular base, a recess formed at a rear of the base for receiving the supporting member. The recess has a first recess and a pair of second recesses extended downward from two opposite ends of the first recess. The supporting member has a horizontal beam accommodated in the first recess, a pair of connecting slices extended downwards from ends of the horizontal beam and accommodated in the second recesses, a pair of fixing slices extended downward from a bottom of each connecting slice. Free ends of the fixing slices are protruded opposite to each other to form protrusions inserted into the PCB for fixing the battery connector firmly on the printed circuit board.
Abstract:
A method and device are provided for adjusting brightness of an optical touch panel. The optical touch panel comprises a microprocessor, a display module including a back light source, and an optical position detection device including optical transmitting devices and optical receiving devices. The method comprises detecting, via the optical receiving devices, a current ambient light level on the display module. The method further comprises generating, via the optical receiving devices, a current ambient light level signal indicative of the current ambient light level and transmitting the current ambient light level signal to the microprocessor. Furthermore, the method comprises adjusting, via the microprocessor, brightness of the back light source based on the current ambient light level signal.
Abstract:
An equalizer is provided. The equalizer comprises a frequency domain a minimum-mean square-error (MMSE) decision feedback equalization (DFE) block having a backward filter co-efficient (BFC) feature adapted to operate in a single carrier environment.
Abstract:
Certain aspects of the present disclosure relate to a technique for constructing a short training field (STF) sequence in a preamble to reduce a peak-to-average power ratio (PAPR) at a transmitter, while having a defined repetition period.
Abstract:
A circuit structure has a channel estimator adapted to receive an input, an equalizer adapted to receive the input and generate an equalized output, and an equalizer training block adapted to receive estimated channel condition information, and provide a set of trained coefficients to the equalizer. The equalized output is used by the channel estimator for at least one subsequent channel estimation. The channel estimator, the equalizer, and the equalizer training block are looped together.
Abstract:
An illumination lamp includes a housing, light source, a light reflecting device and a light path conversion device. The housing defines a light emitting window therein. The light source is disposed in the housing. The light reflecting device is disposed in the housing and has a reflecting surface. The light path conversion device is disposed in the housing. The light path conversion device is configured for converting light rays emitted from the light source into parallel light rays and directing the parallel light rays toward the light reflecting surface of the light reflecting device. The light reflecting device reflects the parallel light rays out of the housing via the light emitting window.
