摘要:
A method comprising determining a remaining electrical charge in a battery of a apparatus using a charge conserving system of the apparatus. The apparatus includes a plurality of hardware and/or software components. The charge conserving system is capable of defining one or a number of charge thresholds. The or each charge threshold corresponds to a quantity of remaining electrical charge in the battery. The method also includes broadcasting a charge status notification, using the charge conserving system, to at least one of a predefined group of the hardware and/or software components when the remaining electrical charge in the battery falls below the or each charge threshold.
摘要:
A low power radio frequency receiver comprises: an antenna (102) for receiving a first radio frequency signal; a radio frequency amplifier (105) for amplifying the first radio frequency signal received by said antenna; an oscillator (1 15) for generating a second radio frequency signal having a predefined frequency and a predefined duty cycle to be mixed with said first radio frequency signal received by said antenna; a mixer (1 10) for mixing the first amplified radio frequency signal with second radio frequency signals and generating a third radio frequency signal; an intermediate frequency filter (120) for passing one or more intermediate frequencies of said third radio frequency signal and attenuating other frequencies of said third signal that are lower or higher than its cutoff frequencies, characterized in that it further comprises: one or more switches (212, 214) for periodically and synchronously switching ON and OFF one or more of said radio frequency amplifier, said oscillator, and said mixer, said switches controlled by means of a control signal having a frequency that is higher than the frequency of data embedded within said first radio frequency signal; and a control unit (225) located within said radio frequency receiver for providing said control signal, wherein each of said switches is connected to a corresponding capacitor (CM2) within said radio frequency amplifier, or oscillator, or mixer, said capacitor storing an operating point of said radio frequency amplifier, or oscillator, or mixer when said radio frequency amplifier, or oscillator, or mixer is switched OFF.
摘要:
Various methods and associated wireless communication mobile terminals are provided that repetitively switch power on and off to a RF transmitter and/or to a RF transceiver, and that regulate the power duty cycle in response to movement of the associated communication terminal. Movement of the communication terminal may be sensed in response to an acceleration signal from an accelerometer, a position signal from a GPS receiver, a light level signal from an ambient light sensor, and/or a pressure level signal from a pressure sensor.
摘要:
A method comprising determining that a minimum operation level of an integrated circuit (100) has been reached and that a sleep mode is therefore allowable; storing minimum operation context information to a RAM (115) in response to determining that the minimum operation level has been reached; switching to a sleep mode code (116) in the RAM (115); and transferring memory control from a primary memory controller (104) to a secondary memory controller (112) wherein only the secondary memory controller (112) controls the RAM (115). The method may include storing the sleep mode code (116) and a wakeup code (117) in the RAM (115) in response to determining that sleep mode is allowable, where the wakeup code (117) restores a minimum operation context using the minimum operation context information stored in the RAM (115). The method may also include placing a plurality of integrated circuit power islands into a sleep mode and leaving a secondary memory controller power island (109) in a normal power mode.
摘要:
Methods and systems are provided for managing electrical power consumption in a mobile phone or other portable communications device having a battery and a display. A series of views forming a flow are retrieved from a memory or other digital storage device for presentation on the display. For each of the views in the flow, performance information relating to the portable communications device is determined while the view is displayed, and this information is stored in the digital storage medium. Upon subsequent retrieval of each view from the digital storage medium, configuring the operation of the portable communications device in response to the stored performance information to thereby manage the electrical power consumption of the portable communications device.
摘要:
A mobile terminal can be controlled, such as being turned on or powered up, according to instructions or commands provided from an external device. Upon being turned on or powered up, the mobile terminal and the external device can authenticate each other and cooperate to perform a desired function or conduct a transaction.
摘要:
A system and method to provide source controlled dynamic power management. An activity detector in a source determines expected future resource usage. Based on that expected usage, the source generates a power management command and sends that command to a destination. The destination then adjusts the power level of the resource based in the command.
