Notification techniques for wireless power transfer systems are described. In one embodiment, for example, an apparatus may comprise a power transmitting unit (PTU) and logic, at least a portion of which is in hardware, the logic to initiate an extraneous object detection procedure to check for a presence of extraneous objects within a transfer field of the PTU during operation of the PTU in a power transfer state, and in response to a detection of an extraneous object, send an extraneous object notification message to a power receiving unit (PRU) and determine whether to maintain the PTU in the power transfer state based on a determination of whether the extraneous object comprises a rogue object. Other embodiments are described and claimed.

A method of preparing nano-dispersed high-all-trans-carotenoid microcapsules is provided, comprising: preparing 10-20% carotenoid suspension by milling the high-all trans-carotenoid crystals with dichloromethane until the particle size thereof is in the range of 2-5 μm, then supplying the suspension together with preheated dichloromethane of another pass into a dissolving tank to obtain a solution of 0.5-2%; delivering the solution together with ethanol or isopropanol into a crystallization device having high gravity rotating packed bed simultaneously and continuously, and then into a wiped-film evaporator for desolvation until the solid content is 10-20%, then a transparent alcohol dispersion of carotenoid is obtained; mashing the alcohol dispersion together with an aqueous solution containing an antioxidant and protective colloid and spray drying to obtain nano-dispersed high-all-trans-carotenoid microcapsules. As the crystals are nano-dispersed and the content of trans-isomer is more than 90%, the carotenoid microcapsules of present inventions exhibit high bioavailability.
摘要:
In one embodiment of the invention, a Fourier transform unit converts unsynchronized data received through multiple antennas to a frequency domain. Also, a spectrum estimation unit determines a power spectrum for the unsynchronized data. A notch filter removes data within a frequency band from additional unsynchronized data based on the power spectrum. A synchronization unit synchronizes the notch filtered data and a noise estimation unit determines a noise covariance matrix between the synchronized data received from multiple antennas. In addition, an equalization unit performs channel equalization on the synchronized data based on the noise covariance matrix.

A computer system may comprise a receiver to perform equalization. The receiver comprises an equalizer. The equalizer may determine locations of a principal tap, a platform noise tap, and a pre-cursor tap in a feedforward path of an equalizer. Also, the equalizer may determine locations of a post-cursor tap, a cross-term tap, and a portable tap in a feedback path of the equalizer. The receiver may align the portable tap in the feedback path with the principal tap in the feedforward path. The platform noise tap may cancel the effect of platform noise on a principal located at the principal tap, thus enabling the computer system to operate effectively in severe platform noise environment. Also, the computer system may operate in statics and portable environment in which platform noise and AGWN may be present.

The disclosure generally relates to methods, system and apparatus to optimize wireless charging by providing user notification when wireless charging efficiency is compromised. In an exemplary embodiment, the charging efficiency value of a device under charge (DUC) is calculated. When the charging efficiency value drops below a predefined threshold, the user is notified to relocate the DUC to a new location with respect to the Power Transmission Unit (PTU) to enhance charging efficiency. In another embodiment, a PTU charging efficiency map is generated to help guide the user for optimal wireless charging.
