Patent number: 11445310Abstract: An electronic device, method, and computer program product enable limiting electromagnetic emissions from current between batteries. A first battery is positioned proximal to an earpiece speaker within the electronic device. At least one second battery is positioned at a different location within the electronic device that is not proximal to the earpiece speaker. A switch is coupled to a first battery proximal to the earpiece speaker among the plurality of batteries. The switch is selectively toggled to limit current drawn from the first battery while the earpiece speaker is operating, in order to reduce baseband electromagnetic emissions emanating from the first battery.Type: GrantFiled: May 20, 2021Date of Patent: September 13, 2022Assignee: Motorola Mobility LLCInventors: Dennis J.

Patent number: 11032655Abstract: An electronic device, method, and computer program product enable limiting electromagnetic emissions from current between batteries. A first battery is positioned proximal to an earpiece speaker within the electronic device. At least one second battery is positioned at a different location within the electronic device that is not proximal to the earpiece speaker. A controller is electrically connected to a switch that is electrically connected in-line with the first battery. The controller selectively toggles the switch between first and second switches state. The controller initiates activation of a first software mode of the electronic device corresponding to operation of the earpiece speaker. In response to detecting the activation, the controller toggles the switch to the first switch state in which the switch limits current drawn from the first battery while the electronic device is in the first software mode, thus reducing baseband electromagnetic emissions emanating from the first battery.Type: GrantFiled: April 10, 2020Date of Patent: June 8, 2021Assignee: Motorola Mobility LLCInventors: Dennis J.

Patent number: 10397875Abstract: In embodiments, a mobile device includes a primary battery as a power source to power components of the mobile device, and includes a secondary battery as an additional power source to power the components of the mobile device. A sensor is implemented to detect a free-fall of the device that indicates an impending secondary battery disconnect event due to the mobile device being dropped. A battery controller is implemented to receive a sensor input of the detected free-fall from the sensor. The battery controller can then switch from the secondary battery to the primary battery as the power source based on the detected free-fall of the mobile device. The battery controller can switch back from the primary battery to the secondary battery as the power source based on a lack of acceleration of the mobile device.Type: GrantFiled: April 12, 2017Date of Patent: August 27, 2019Assignee: Motorola Mobility LLCInventors: Jiri Slaby, Mark J.

Patent number: 8862416Abstract: A method and device for extending the useful life of an energy storage device, for a mobile computing device is described. The method (150) can include the steps of: running (155) a first application in synchronous communication with a first application server; detecting (160) energy expenditure while running the first application; and synchronizing (165) a subsequent application based on the detected energy expenditure, by: continuing to communicate with the subsequent application if the detected energy expenditure is below a threshold, and discontinuing communication if the detected energy expenditure is above a threshold. Advantageously, this method can provide substantial energy savings in mobile computing device applications.Type: GrantFiled: April 27, 2009Date of Patent: October 14, 2014Assignee: Motorola Mobility LLCInventors: Gregory R.

Publication number: 20140118520Abstract: An electronic device and a method for enabling seamless access to the electronic device are disclosed herein. The method includes assessing, via a first processor, an initial stationary state of the electronic device; and monitoring at least one sensor of the electronic device to determine user interaction with the electronic device. In addition, motion of the electronic device is detected as is any subsequent secondary stationary state within a predetermined time period. An authentication procedure is initialized in the background based on proximity to a user and expiration of the predetermined time period.Type: ApplicationFiled: October 29, 2012Publication date: May 1, 2014Applicant: MOTOROLA MOBILITY LLCInventors: Jiri Slaby, Roger W.

Patent number: 8228832Abstract: An USSD transporting method (200) and mobile computing device (410) are described. The method (200) can include the steps of: providing a data pushing operation (210) over a universal supplementary services data (USSD) channel from the application server to the mobile device client; and initiating a data pulling operation (220) over an internet protocol (IP) channel by the mobile device client, in response to the pushing operation. Advantageously, for short data transfers, such as application server push notifications, USSD messages require lower power drain than packet data, due to the longer time to transition to an RRC idle state after the data transfer is completed. Also, push notifications can be sent over USSD without an open IP session, thereby saving the client from having to maintain a persistent IP session, while employing alternate pulling transport means such as wireless LAN which require lower power drain than a wide area network.Type: GrantFiled: January 25, 2010Date of Patent: July 24, 2012Assignee: Motorola Mobility, Inc.Inventors: Gregory R.

Patent number: 7978088Abstract: A wireless communication device (200) and method (300) adapted to prolong the useful life of an energy storage device is disclosed. In its simplest form, it can include: determining (310) a limit temperature discharge energy rate of an energy storage device; sensing (320) a temperature range threshold in proximity to the energy storage device; and adjusting (330) a discharge energy rate in response to the determined limit temperature discharge energy rate (310) and sensed temperature range threshold (320). The device (200) and method (300) can automatically and dynamically manage current drain of an energy storage device when a certain temperature range threshold is reached, to maintain the energy storage device within desired specifications and tolerances. This can prolong the useful life of the energy storage device and help to maintain a maximum recharging capacity.Type: GrantFiled: May 30, 2008Date of Patent: July 12, 2011Assignee: Motorola Mobility, Inc.Inventors: Greg R Black, John P Boos, Mark J Carlson

Patent number: 7343147Abstract: Automated software loading into a battery-less mobile phone is accomplished through attachment of a special non-standard USB On-The-Go cable to a serial connector of the mobile phone, thereby delivering power supply and unique signals for placing the phone in a special mode of operation used for production or distribution. In operation, when a unique non-standard voltage is asserted on the identification (ID) pin of the USB connector interface, it is detected by special circuitry in the serial connector. The circuitry then enables power supply to the battery-less phone and generates a turn-on signal directing the mobile phone to automatically power-on and enter into a particular state of operation, for example a test or software loading mode. Because this process is automatic, the efficiency of software loading or testing during production or distribution of the mobile device is improved.Type: GrantFiled: April 4, 2005Date of Patent: March 11, 2008Assignee: Freescale Semiconductor, Inc.Inventors: Alan L.

Patent number: 7184794Abstract: A highly versatile interface that is capable of digital and audio signal coupling is provided. The interface comprises contacts (122, 124, 216, 218) that are used to couple both audio and digital signals, and separate contacts (126, 220) that are used initiate and negotiate signaling mode transitions. Transitions can be effected without creating glitches, e.g., audible noise, in audio signals that are being coupled through the interface.Type: GrantFiled: September 9, 2004Date of Patent: February 27, 2007Assignee: Motorola, Inc.Inventors: David M. Hess, Mark J. Carlson, Timothy M. McCune
