    摘要： Manganese oxide nanoparticles having a chemical composition that includes Mn3O4, a sponge like morphology and a particle size from about 65 to about 95 nanometers may be formed by calcining a manganese hydroxide material at a temperature from about 200 to about 400 degrees centigrade for a time period from about 1 to about 20 hours in an oxygen containing environment. The particular manganese oxide nanoparticles with the foregoing physical features may be used within a battery component, and in particular an anode within a lithium battery to provide enhanced performance.

    摘要： Power transmitting unit (PTU) usable with a wireless power transfer system to supply power and maintain a control signaling link to a local power receiving unit (PRU). A cross-connection circumstance between the PTU and a remote PRU is determined, where a control signaling link between the PTU and the remote PRU is established in an absence of power transmission to the remote PRU from the PTU. In response to the cross-connection circumstance, the control signaling link with the remote PRU is terminated while the supply of power and the control signaling link with the local PRU is maintained. In a related embodiment, a wrong-placement characteristic where power is transferred to a rogue local PRU in an absence of a control signaling link with that PRU, is detected. In response, the supply of power is maintained for at least a waiting period.

    摘要： Embodiments of a method and an apparatus for improving the performance of coexisting wireless radio signals are described. In one embodiment, the method includes detecting burst-type interference based on a packet error rate and a transmission rate associated with a transmitter. The method further includes setting the transmission rate in accordance with a burst-type rate-adaptation mode to increase data throughput.

    摘要： Techniques are described that can be used to perform one or more of the following actions in order to reduce signal interference between WLAN and BlueTooth radios that are proximate to one another. One action is to selectively reduce a filter bandwidth in a WLAN radio applied to a received WLAN radio signal to reduce BlueTooth signal interference. An additional or alternative action is to selectively indicate a WLAN radio channel bandwidth larger than a channel bandwidth used for the WLAN radio so that the BlueTooth radio avoids transmitting over the indicated channel bandwidth. An additional or alternative action is to selectively reduce BlueTooth transmitter power in response to antenna isolation between BT and WLAN radio being less than a first threshold in order to reduce the likelihood of WLAN radio front end saturation.

    摘要： A method, apparatus and system for medium access control is provided. Time slots configured to include mini slots at the beginnings thereof. Devices are assigned time slot, mini slot combinations as transmission opportunities. A device can attempt to use a transmission opportunity when it has a packet to send, by beginning data transmission in its assigned slot and mini slot and potentially continuing the transmission up until the end of the assigned slot. If another device is already transmitting in the assigned slot, the device refrains from using its transmission opportunity. Higher priority devices can be assigned transmission opportunities corresponding to earlier mini slots within a slot. In some embodiments, multiple devices can be assigned the same transmission opportunity and a collision detection mechanism can be employed. In some embodiments, all devices detect if a slot is idle and advance the beginning of the next slot upon such detection.

    摘要： The disclosure provides a method for frequency reuse in a wireless relay scenario, wherein a center frequency spectrum, an edge frequency spectrum and a random access frequency spectrum are pre-allocated to a cell according to a scenario parameter in the cell; load conditions of all mobile stations (MSs) covered by each relay station (RS) in the cell is calculated and reported to a base station (BS); the BS allocates the random access frequency spectrum to an RS according to load conditions of all RSs and schedules MSs. The disclosure also provides a system for frequency reuse in a wireless relay scenario. With the method and system above, the frequency spectrum planning is configurable, the random access frequency spectrum is introduced, and both the load balancing and user fairness are taken into consideration, which improves the throughput at the edge of the cell, especially can increase the throughput for the users whose throughput ranks poorly.
