Clustering geofence-based alerts for mobile devices
A geofence management system obtains location data for points of interest. The geofence management system determines, at the option of the user, the location of a user mobile computing device relative to specific points of interest and alerts the user when the user nears the points of interest.

System and method for allowing a user to opt for automatic or selectively sending of media
The present invention is directed to a system and method which allows for the seamless integration of the sending mechanism with the media acquiring mechanism of a portable device. In this manner the end-user has instant access to media sharing with complete control over how the media is shared. This integration is accomplished by presenting to the user a series of screens that are available directly from the media creation applications (e.g. cameras or audio recorders) and media viewing applications (e.g. photo galleries or screen savers) on the device. When a photo (or other media) is captured or viewed, a series of pre-established processing options, including on-device uses for the media, internet services and accounts, email addresses and/or phone numbers to which the media can be sent are presented to the user. Some options require no further user interaction. Defaults are also available which require no user interaction at all, combining together the manual selection of certain processing options or destinations with the automatic selection of other processing options or destinations. Thus, the sending process becomes essentially a selection process allowing the user to override defaults by either selecting from choices tailored to the user including already known address information of potential recipients or to allow the media to be automatically sent to a previously identified location according to the current “default” user preferences. In the situation where a new address or phone number is desired, the user can add such information in a simple and straight-forward manner. |

Coordination of M2M device operation by M2M device managers in a LAN
Teachings herein include a first machine-to-machine (M2M) device manager in a local area network (LAN). The first manager receives operating information for a first M2M device managed by the first manager. This operating information may indicate, for example, the operating state (e.g., on or off) of the first device. Responsive to receiving this operating information, the first manager coordinates operation of a second M2M device that is managed by a second M2M device manager in the LAN.

Efficient TCP ACK prioritization in wireless networks
An improved acknowledgement (ACK) prioritization scheme is disclosed that provides ACKs with a lower block error rate (BLER) (as opposed to data) over an air interface, provides a separate radio bearer for ACKs, and successively increases the priority of ACKs for each retransmission required.

When retransmissions are required for an ACK packet, the scheduling prioritization is increased successively for each ACK retransmission required. |

Delayed reactive electrical consumption mitigation
The electrical consumption mitigation provided by energy storage systems can be unreliable when a consumption peak lasts long enough to deplete the energy stored and the remainder of the peak is unmitigated. By implementing a waiting period between detecting the peak and discharging the energy storage in which characteristics of the peak are observed, a peak mitigation system can lengthen the effective discharge duration of the energy storage system and prevent unmitigated plateaus from appearing. For example, when a consumption plateau is detected, the system may discharge at a slower rate than when a spike is detected in order to prolong mitigation activities before the conclusion of the plateau. Thus otherwise-incurred demand-related utility charges can be reduced without having to increase the capacity of the mitigation system. In some cases, these processes are performed with respect to the bounds of demand-averaged time periods used to calculate demand charges. |

In one embodiment, the resistive switching element comprises at least three layers of variable resistance materials to increase the number of logic states. Each variable resistance layer may have an associated high resistance state and an associated low resistance state. As the resistance of each variable resistance layer determines the digital data bit that is stored, the multiple variable resistance layers per memory element allows for additional data storage without the need to further increase the density of nonvolatile memory devices. Typically, resistive switching memory elements may be formed as part of a high-capacity nonvolatile memory integrated circuit, which can be used in various electronic devices, such as digital cameras, mobile telephones, handheld computers, and music players. |
