Abstract: A micro piezoelectric pump module includes a microprocessor, a driving element, and a piezoelectric pump. The driving element is connected to the microprocessor to receive a modulating signal and a control signal and to output a driving signal. The driving signal includes a driving voltage and a driving frequency. The piezoelectric pump is actuated by the driving signal, and the piezoelectric pump is set to be actuated at an actuation frequency and be applied with an actuation voltage value. The microprocessor drives the driving element to output the driving voltage having an initial voltage value at the driving frequency to the piezoelectric pump, and adjusts the driving frequency to the same with the actuation frequency. After the driving frequency is adjusted to reach the actuation frequency, the microprocessor drives the driving element to gradually increase the initial voltage value to reach the actuation voltage value.

Abstract: A network base station can select, for each of one or more attached terminals, a respective downlink transmission mode (DTM) based at least in part on respective channel condition information (CCI). The base station can determine a subframe allocation of DTMs to subframes of a radio frame, and transmit downlink data to terminals based the subframe allocation. Additionally or alternatively, the base station can receive load information from a second base station associated with a different access network and determine the subframe allocation based on the load information. The subframe allocation can associate a specific access network with each subframe. Additionally or alternatively, the base station can send the subframe allocation to the second base station. Additionally or alternatively, the base station can determine a proportion of GBR traffic of a particular DTM, determine a reference-signal transmission rate associated with that DTM, and transmit reference signals accordingly.

Abstract: Mobile networks may be configured to broadcast wireless emergency alert (WEA) messages to receiving mobile devices. A mobile device within the network may receive a WEA message including data defining a geographic region associated with the message. Using the data defining the geographic region for the WEA message, the mobile device may perform location-based geofencing techniques to determine whether to present a notification in response to the WEA message. In various examples, a mobile device may calculate an offset distance based on a transgression parameter and may determine a second geographic region using the offset distance. The mobile device also may determine its current location and compare the location to the second geographic region to determine whether to present the WEA message, thereby limiting and/or minimizing the negative effects of potential undershoot and overshoot errors caused by inaccurate location determinations by mobile devices.
