    Abstract: 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.

  • Patent number: 9532306
    Abstract: 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.

  • Patent number: 9485727
    Abstract: 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.

  • Patent number: 9480020
    Abstract: 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.

  • Patent number: 9462555
    Abstract: Methods, systems, and devices for low power consumption in wireless communication systems are disclosed herein. An evolved node B (eNodeB) is configured to provide a connection reconfiguration message to user equipment (UE) connected to the eNodeB, the connection reconfiguration message configuring the UE to indicate a power preference. The eNodeB receives assistance information from the UE. The assistance information includes a low power preference indication and a timer length, wherein the timer length indicates a preferred duration for a low power mode. The eNodeB provides, in response to receiving the assistance information, a connection release message to the UE. The connection release message includes paging discontinuous reception (DRX) information that includes the timer length.

  • Patent number: 9461684
    Abstract: Methods and apparatuses are presented for acquiring a wireless system by a multi-subscriber identity module (SIM) user equipment (UE). For example, an example method for acquiring a wireless system is presented that includes conducting, by a first subscription corresponding to a first SIM of the UE, a call using a shared radio resource of the UE. In addition, the example method may include predicting, upon completion of the call, a pilot timing error and a frequency error associated with a pilot signal of a network associated with a second subscription corresponding to a second SIM of the UE. In addition, the example method may include attempting to acquire the pilot signal based on the pilot timing error and the frequency error. As such, the example method may allow the multi-SIM UE to more quickly acquire a wireless system relative to legacy methods. Other aspects, embodiments, and features are also claimed and described.

  • Patent number: 9456413
    Abstract: Apparatuses, systems and methods for reducing power consumption during standby operation of a mobile device are disclosed. A page decoding algorithm can be stored in nonvolatile memory during standby. The page decoding algorithm can be executed from the nonvolatile memory, when the mobile device is awakened from a sleep state to determine if there is any activity such as an incoming call. No power is required for the nonvolatile memory to maintain storage of the algorithm so that the power requirement during standby of the mobile device is reduced.
