摘要： In one aspect there is provided a computer-implemented method for encrypting a data element. The method includes generating a symmetric key and encrypting the data element using the symmetric key. The method also includes identifying one or more entities in a policy database that are authorized to access the data element, and retrieving a public key associated with each of the one or more entities. The method also includes, for each entity of the entities that are authorized to access the data element, encrypting the symmetric key using the public key associated with the entity to obtain an encrypted symmetric key, and appending the encrypted symmetric key to a file storing the encrypted data element.

摘要： A power distribution network includes multiple charge storage components and multiple charging circuits to control the charging and discharging of the charge storage components, which may comprise a battery and a supercapacitor. By appropriate arrangement and selection of the storage components, ripple in the power supply voltage, whose propagation to other components relying on the power distribution network may cause an audible buzz, may be significantly reduced. Additionally, appropriate arrangement and selection of the storage components, electromagnetic interference may also be significantly reduced.

摘要： A communications subsystem for a wireless device for correcting errors in a reference frequency signal. The communications subsystem comprises a frequency generator for generating the reference frequency signal and a closed loop reference frequency correction module that generates a reference frequency adjustment signal for correcting the reference frequency signal when the communications subsystem operates in closed loop mode. The subsystem further includes an open loop frequency correction means that that samples values of the reference frequency adjustment signal during the closed loop mode and generates a frequency correction signal for correcting the reference frequency signal when the communications subsystem operates in a mode other than closed loop mode.

摘要： A system and method for speed measurement of a mobile device, using an speed sensor such as a satellite navigation system or an accelerometer, does not need such speed sensor to be continually activated. The system and method make use of a monitor for monitoring at least one motion indicium for indicating that the speed of the mobile device is above an initial threshold, including but not limited to: monitoring the Doppler shift measurements of a timing signal; monitoring the timing advance of a cellular radio signal; monitoring the number of base stations visible to the mobile device; monitoring the frequency of base station handover, however determined; monitoring the level crossings and/or the autocorrelation of an RSSI signal; and/or triangulation of the position of the mobile device. When the monitor determines that the mobile device may be travelling in excess of a threshold speed, a speed sensor is activated to confirm the indication. If the speed sensor determines that the mobile device is travelling at a speed below a second threshold, the speed sensor is deactivated.

摘要： A speed parameter or channel quality parameter are determined in a mobile device based on variation in frequency offset measurement. A higher variation in the frequency offset measurement reflects a poorer channel quality and a higher speed; a lower variation in the frequency offset measurement reflects a better channel quality and a lower speed. The parameter(s) may be fed back to the system and used, for example, to make adaptive modulation and coding decisions.

摘要： A power management system and method for a wireless communication device generates an average desired transmit power signal based on at least one of a received signal strength indicator signal and a power control instruction signal from a base station. A power supply level adjustment signal is generated based on the data parameters of an outgoing data stream and at least one environmental information signal. A combination of the power supply level adjustment signal and the average desired transmit power or a gain control signal and an altered version of the power supply level adjustment signal is used to generate a variable power supply signal that is provided to an output amplifier block for sufficiently generating outgoing wireless device radio signals while reducing power loss in the output amplifier block.
