Patent number: 7979048Abstract: Image rejection factors are calibrated for a receiver circuit (106) during an initialization period. The image rejection factors are stored in a quasi non-volatile memory (124) associated with the receiver circuit (106). The quasi non-volatile memory (124) is powered from a first source (VDD A) during a first receiver mode and from a second source (VIO) during a second receiver mode.Type: GrantFiled: September 15, 2005Date of Patent: July 12, 2011Assignee: Silicon Laboratories Inc.Inventors: Donald A. Kerth, Brian D. Green, Augusto M. Marques

Patent number: 7957775Abstract: A low battery notification service is provided to a user of a wireless device capable of monitoring the voltage level of its internal battery and sending a low battery warning message. The messages are received at a service provider that maintains subscriber profiles associated with a subscriber's wireless device. When a low battery warning message is received, a wireless device identifier in the warning message is used to access a notification list included in a stored subscriber profile. Notification list entries are selected based on their assigned priorities and the existence or absence of conditions of use, permitting low battery notifications to be sent to target systems on the notification list until an acceptable response is received or the notification list is exhausted.Type: GrantFiled: November 5, 2007Date of Patent: June 7, 2011Assignee: International Business Machines CorporationInventors: Lloyd W. Allen, Jr., Jana Helton Jenkins, Steven Michael Miller

Patent number: 7953459Abstract: A system and method for providing a low power warning in a portable communication device based on predicted device utilization. Various aspects of the present invention may comprise monitoring power utilization for a portable communication device. A power utilization profile may be determined based, at least in part, on the results of the power utilization monitoring. Power availability for the portable communication device may be determined. Future power need for the portable communication device may be predicted based, at least in part, on the determined power utilization profile. The predicted future power need and the determined power availability may be analyzed to determine whether to generate a warning indicating a potential future power shortage. If it is determined that a potential future power shortage warning should be generated, such a warning may be generated. Such a warning may, for example, be generated in accordance with user specifications.Type: GrantFiled: June 15, 2009Date of Patent: May 31, 2011Assignee: Broadcom CorporationInventors: Neil Y. Kim, Pieter Vorenkamp, Sumant Ranganathan, Chun-Ying Chen

Patent number: 7937119Abstract: In a mobile terminal having an automatic startup mode of a television signal receiving function using a timer, startup is properly controlled in consideration of remaining battery capacity to thereby prevent an occurrence of unexpected lack of battery capacity. In a state where an alarm mode using a television broadcast or an FM broadcast has been set, a control unit makes low voltage determination of a battery at a time point when a time has been up. When an output voltage value of the battery is lower than a threshold, the control unit outputs an alarm sound from a speaker instead of starting up a TV receiver and causes a display to display a low voltage message.Type: GrantFiled: August 2, 2006Date of Patent: May 3, 2011Assignee: Fujitsu Toshiba Mobile Communications LimitedInventor: Masae Arai

Patent number: 7889688Abstract: A radio communication apparatus has a battery, a transmit buffer for temporarily accumulating packets to be sent, a battery state monitoring unit for monitoring a battery state of the battery, and a traffic control unit. The traffic control unit determines a packet burst length and an interval time between the packet bursts in order to obtain charge recovery effect based on the battery state, and controls so as to take out data packets of the packet burst length from the transmit buffer for every interval time between the packet bursts of the packet burst.Type: GrantFiled: April 19, 2007Date of Patent: February 15, 2011Assignee: KDDI CorporationInventors: Takeshi Kitahara, Hajime Nakamura, Satoshi Konishi

Patent number: 7769544Abstract: An autonomous vehicle collision/crossing warning system provides for simple, inexpensive and decentralized installation, operation and maintenance of a reliable vehicle collision/crossing warning system. The autonomous warning system preferably utilizes a single frequency TDM radio communication network with GPS clock synchronization, time slot arbitration and connectionless UDP protocol to broadcast messages among vehicles and components in the warning system. Adaptive localized mapping of components of interest within the warning system eliminates the need for centralized databases or coordination and control systems and enables new vehicles and warning systems to be easily added to the system in a decentralized manner. Preferably, stationary warning systems are deployed as multiple self-powered units each equipped to receive broadcast messages and to communicate with the other units by a low power RF channel in a redundant Master-Slave configuration.Type: GrantFiled: May 7, 2002Date of Patent: August 3, 2010Assignee: Ansaldo STS USA, Inc.Inventors: James L. Blesener, Gordon M. Melby

Patent number: 7725138Abstract: An apparatus (100) is provided for powering an in-battery electronic application module (118) without the use of an external on/off switch. A battery pack (102) is electrically coupled to a radio (104) via three interface contacts: power (108), ground (112) and single-wire serial data port (110). Circuitry is included within the battery pack (102) to sense and monitor data activity on the single-wire serial data port (110) generated as the radio (104) is turned on. Based on the level and timing (200) of the data activity present on the single-wire serial port (110), the electronic application module (118) can automatically be turned on (208), remain on (210) and turned off (212).Type: GrantFiled: December 14, 2006Date of Patent: May 25, 2010Assignee: Motorola, Inc.Inventor: Richard Herrera

Patent number: 7680479Abstract: An urgent message apparatus mounted in a vehicle, for transmitting, in an emergency, an urgent message with a backup battery with the use of a low-earth orbit orbiting satellite, detects a current position of the vehicle; a obtaining part obtaining a communication not-possible time zone of the low-earth orbit orbiting satellite, for the current position of the vehicle detected by the position detecting part; calculates a power amount to be consumed when the backup battery is maintained in a transmission standby state during the communication not-possible time zone obtained by the obtaining part; measures remaining power of the backup battery; compares a sum of a power amount required for transmitting the urgent message and the power amount calculated by the calculating part, with the remaining power measured by the measuring part; and determines that charging or replacement of the backup battery is required when the sum is larger.Type: GrantFiled: September 26, 2006Date of Patent: March 16, 2010Assignee: Toyota Jidosha Kabushiki KaishaInventor: Junichi Nishida

Patent number: 7565181Abstract: A mobile telecommunications terminal is provided, which makes possible, so as to use the least possible amount of power, a query of messages present for the mobile telecommunications terminal in a telecommunications network. The mobile telecommunications terminal includes a receiving device for receiving messages from the telecommunications network in a receive mode. At the mobile telecommunications terminal, a query mode can be established, in which a control unit, in the event that the receive mode is switched off, activates the receive mode at least one first predetermined time. The control unit checks whether, within a second predetermined time period after the activation of the receive mode, information was received in the receiving device regarding at least one message present in the telecommunications network (10) for the mobile telecommunications terminal.Type: GrantFiled: November 15, 2000Date of Patent: July 21, 2009Assignee: IPCOM GmbH & Co. KGInventors: Martin Hans, Frank Kowalewski, Josef Laumen, Gunnar Schmidt, Siegfried Baer, Mark Beckmann
