    摘要： Technologies are generally described for selectively charging a capacitor coupled to a memory. Example electronic devices described herein may include a memory; a capacitor coupled to the memory; a power supply configured to supply power at least to the capacitor; a switch coupled between the power supply and the capacitor; and a switch controller coupled to the switch and configured to: determine whether the electronic device is in a safety mode or in a normal mode, and control an operation of the switch, based on the determination. So, the supply of the power from the power supply to the capacitor is selectively controlled.

    摘要： Technologies are generally described for detecting proximity of a client device to a base station in a wireless communication system. Example base station may include a proximity detector and an operation mode controller. The proximity detector may analyze a property of a signal transmitted by a client device to detect an envelope of the signal including a buzz-type waveform. If the envelope of the signal is determined to include a buzz-type waveform, the client device is determined to be within communication range of the base station. Further, the operation mode controller may convert a current operation mode of the base station to a particular operation mode that enables the base station to support communication by the client device. In some embodiments, the buzz-type waveform may be a waveform of an uplink control signal that is transmitted by the client device when it is not actively engaged in communication.

    摘要： Technologies are generally described for identifying whether a propagation path between a mobile device and an access point is line-of-sight. In some examples, a method performed under control of a mobile device may include receiving, from an access point, a first signal transmitted at a first frequency band; receiving, from the access point, a second signal transmitted at a second frequency band; measuring a difference value between propagation properties of the first signal and the second signal; and identifying whether a propagation path between the mobile device and the access point is line-of-sight or non-line-of-sight based at least in part on the difference value.

    摘要： Technologies generally described herein relate to connection of a mobile device to a base station in a wireless communication system. Example mobile devices may include a receiver, a data communication module, a switch module, and a signal consolidator. The receiver may be configured to receive, from a base station through a cellular band, a first control signal including control information regarding the base station. The data communication module may be configured to communicate with the base station through a non-cellular band. The switch module may be coupled to the receiver and to the data communication module, and configured to determine that a power level of the first control signal is higher than a first threshold value and activate the data communication module in response to the determination. The data communication module may be further configured to receive a second control signal including the control information from the base station through the non-cellular band. The signal consolidator may be coupled to the receiver and the data communication module, and configured to obtain the control information regarding the base station from at least one of the received first control signal or the received second control signal.

    摘要： Technologies are generally described for activation of actuators based on sensed user characteristics, such as orientation. In some examples, an access control system may be configured to activate an actuator upon determining that an activation device is both in proximity to and has a similar orientation to the actuator. The access control system may be configured to determine orientation similarity by determining an orientation associated with the activation device, determining an orientation associated with the actuator, and comparing a difference between the two orientations to an activation threshold. The actuator may be associated with an entryway such as a building doorway, a room doorway, or a vehicle door, or may be associated with a container such as a safe or vehicle trunk.
