Patent number: 9533772Abstract: A visual search assistance system and related operating method are disclosed. An exemplary embodiment of the method dynamically determines a desired line-of-sight vector from an occupant of a vehicle to a visual target, and dynamically determines, with an onboard tracking system of the vehicle, an actual line-of-sight vector for the occupant of the vehicle. The actual line-of-sight vector is temporally associated with the desired line-of-sight vector. The method compares the actual line-of-sight vector against the desired line-of-sight vector to obtain a difference measurement, and generates a notification when the obtained difference measurement exceeds a threshold value. The notification provides guidance to redirect a gaze direction of the occupant toward the visual target.Type: GrantFiled: July 9, 2014Date of Patent: January 3, 2017Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Pedro Davalos, Robert E. De Mers, John F. L. Schmidt, Mohammed Ibrahim Mohideen

Patent number: 9538470Abstract: Disclosed are a method and an apparatus for updating a listen interval in a wireless communication system. To this end, a method for updating a listen interval by a station (STA) of a wireless communication system may comprise, if an operation mode of the station is changed, a request frame including information indicating that the operation mode of the station is changed, to an access point (AP); and receiving a response frame in response to the request frame from the AP. If a value of a listen interval of the station is changed as the operation mode of the station is changed, the request frame further include a value of a new listen interval of the station.Type: GrantFiled: September 17, 2013Date of Patent: January 3, 2017Assignee: LG ELECTRONICS INC.Inventors: Jinsoo Choi, Yongho Seok, Jeongki Kim, Hangyu Cho

Patent number: 9532306Abstract: A method for Internet Protocol (IP)-based sleep mode control is disclosed. The method includes, when a request for a sleep mode is made from any one of internal hosts, transmitting a sleep mode request message to an internal router, updating the state of the corresponding host to a sleep mode, transmitting a sleep mode ACK message to the internal host requiring a sleep mode, switching to a sleep mode, and transmitting information about the internal hosts in a sleep mode to the external hosts of a history information list because the internal router stores the history information of the external hosts that communicated with the internal hosts in a sleep mode in the form of a list.Type: GrantFiled: August 21, 2014Date of Patent: December 27, 2016Assignee: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Yonggeun Hong, Myungki Shin, Hyoungjun Kim

Patent number: 9524216Abstract: Disclosed is a method for information backup, comprising: an information backup device detects a battery volume of a mobile terminal and determines whether or not the battery volume reaches a preset low-battery alarming threshold; and the information backup device stores contact information stored in the mobile terminal into a backup memory card when the battery volume reduces the low-battery alarming threshold. The present disclosure also discloses a device and a mobile terminal for information backup. The present disclosure enables the user of a mobile terminal to timely view contact information when the mobile terminal runs out of power.Type: GrantFiled: May 14, 2012Date of Patent: December 20, 2016Assignee: ZTE CorporationInventors: Cuihua Zhao, Tao Li

Patent number: 9485727Abstract: Techniques for determining if it is safe for a mobile device to transition directly from a traffic session to a paging mode and for avoiding network re-synchronization procedures in stationary M2M devices are disclosed. It may be safe for direct transition if before-call and in-call network parameters correspond. If safe, the mobile device may transition from the traffic session directly to the paging mode to begin immediately monitoring the paging channel. In stationary M2M devices, paging information is stored before the traffic session and, once the traffic session is complete, the M2M device may be configured to receive paging messaging based on the stored paging information. The M2M device may also store system access information and confirm the validity of the information before returning to the sleep state. The stationary M2M device avoids network re-synchronization procedures. Other aspects, embodiments, and features are also claimed and described.Type: GrantFiled: April 4, 2013Date of Patent: November 1, 2016Assignee: QUALCOMM IncorporatedInventors: Alvin S. Ng, Troy R. Curtiss, Stanley Tsai, Joshua T. MacDonald, Chunchung Chan, Tak Wai Wu, Ammar T. Kitabi

Patent number: 9480020Abstract: A method for controlling a Bluetooth connection includes turning off an ignition of a vehicle. It is determined whether a terminal connected to a Bluetooth system provided in the vehicle exists or not. When it is determined that the connected terminal exists as a result of determining, a disconnection command for the Bluetooth connection is transmitted from the vehicle to the terminal. The Bluetooth system waits for a time predetermined by the Bluetooth system, after transmitting the disconnection command. After waiting for the predetermined time, it is determined whether a disconnection confirmation message responding to the disconnection command is received from the terminal or not. When it is determined that the disconnection message is received as a result of determining whether the disconnection message is received or not, the Bluetooth system is caused to enter into a sleep mode.Type: GrantFiled: January 4, 2016Date of Patent: October 25, 2016Assignees: HYUNDAI MOTOR COMPANY, KIA MOTORS CORPORATION, HYUNDAI MOBIS CO., LTD.Inventors: Seong Soo Yae, Ji Un Kim
