20090055484 | SYSTEM AND METHOD FOR REPRESENTATION OF ELECTRONIC MAIL USERS USING AVATARS - There is disclosed a system and method for graphically representing an email user. In an embodiment, the method may comprise: at a sending communication device, sending an accompanying avatar or avatar identifier with an email message; at a receiving communication device, scanning an email message for an accompanying avatar or avatar identifier, and if an accompanying avatar is found, displaying the avatar with the email message in a message list user interface; if an accompanying avatar identifier is found, searching for an avatar locally stored at the receiving communication device, and displaying the locally stored avatar if found. The method further comprises sending and receiving a mood avatar or mood avatar identifier indicative of the mood of the user. The mood avatar may be selected at the sending communication device using a mood analyzer, or receiving a mood input from a user. | 02-26-2009 |
20090296618 | POWER SAVING VIA VARIABLE LISTEN INTERVALS IN A WLAN - A wireless client device is associated with an access point in an association having a value for a listen interval parameter. The wireless client device determines, according to predefined considerations, a different value for the listen interval parameter, and declares the different value for the listen interval parameter in a wireless transmission to the access point. The listen interval parameter specifies a number of beacon intervals that can pass from a time the wireless client device listens for a beacon frame from the access point before the wireless client device listens for a next beacon frame from the access point. | 12-03-2009 |
20100014499 | Probabilistic Location Prediction for a Mobile Station - A probabilistic prediction is made of the location of a wireless-enabled mobile station in a wireless local area network. The prediction includes calculating a vector representing movement of the mobile station through a space in which two or more access points of the network are located, and determining a region surrounding the vector in which the mobile station has at least a given probability to be located within a certain period of time. | 01-21-2010 |
20110169981 | CAMERA WITH AUTOMATIC FLUORESCENT LIGHTING MODE - A novel method and apparatus for controlling operation of a photosensor array in a portable electronic device to reduce flicker resulting from fluorescent light having a periodic intensity. The method comprises selecting a time zone in which the device is to be operated, correlating the time zone with a corresponding frequency of the fluorescent light, and signaling the photosensor array to operate in accordance with a mode optimized to reduce flicker based on the selected time zone. | 07-14-2011 |
20110182276 | Methods And Apparatus For Reducing Power Consumption For Mobile Devices Using Broadcast-To-Unicast Message Conversion - Techniques for use in communicating messages to a mobile device operative in a wireless network are described. A communication network receives a broadcast message which includes a protocol type identifier in a protocol type identifier field. The communication network identifies whether the protocol type of the broadcast message matches one of a plurality of protocol types stored in association with an identification of the mobile device. If the protocol type of the broadcast message matches one of the stored protocol types, then the communication network produces, from the broadcast message, a unicast message which includes information from the broadcast message, and causes the unicast message to be sent to the mobile device in the wireless network. | 07-28-2011 |
20110207486 | Probabilistic Location Prediction for a Mobile Station - A probabilistic prediction is made of the location of a wireless-enabled mobile station in a wireless local area network. The prediction includes calculating a vector representing movement of the mobile station through a space in which two or more access points of the network are located, and determining a region surrounding the vector in which the mobile station has at least a given probability to be located within a certain period of time. | 08-25-2011 |
20110321112 | SYSTEM AND METHOD FOR ADJUSTING TRANSMISSION DATA RATES TO A DEVICE IN A COMMUNICATION NETWORK - The disclosure relates to a system and method for adjusting a characteristic of a data transmission in order to maintain a rate of transmission. For the method, it comprises: monitoring for initiation of the data transmission to the device; identifying characteristics of the device relating to the data transmission; automatically adjusting the transmission rate according to a preset transmission rate progression established for the communication network; and adjusting characteristics of the data transmission to allow the characteristics of data transmission to conform to the characteristics of the device while maintaining the transmission rate for the device. | 12-29-2011 |
20130003632 | Methods And Apparatus For Reducing Power Consumption For Mobile Devices Using Broadcast-To-Unicast Message Conversion - A mobile device sends to a message a wireless network. The message indicates a plurality of different protocol types of broadcast messages to be processed as broadcast-to-unicast messages during a low power mode of operation of the mobile device. The protocol type of a given broadcast message is identifiable in a protocol identifier field of the broadcast message. The mobile device maintains its wireless receiver in a powered down state during the low power mode of operation while broadcast messages are broadcasted from the wireless network. For each broadcast message of each said indicated protocol type provided in the message sent to the wireless network, the mobile device monitors to receive via the wireless receiver a unicast message from the wireless network. The mobile device identifies broadcast message information of the broadcast message within the unicast message. | 01-03-2013 |

The wireless client device determines, according to predefined considerations, a different value for the listen interval parameter, and declares the different value for the listen interval parameter in a wireless transmission to the access point. The listen interval parameter specifies a number of beacon intervals that can pass from a time the wireless client device listens for a beacon frame from the access point before the wireless client device listens for a next beacon frame from the access point. | 04-18-2013 |
20130150020 | SYSTEM AND METHOD OF REMOTELY LOCATING A LOST MOBILE COMMUNICATION DEVICE - A system and method of locating a lost wireless communication device is provided. A remote server is contacted to indicate that the wireless communication device is lost. A lost device policy setting is then activated in a database coupled to the remote server, the lost device policy setting indicating that the wireless communication device is lost. In response to activation of the lost device policy setting, a remote location command is then transmitted from the remote server to the wireless communication device via a wireless network. The remote location command is subsequently received at the lost wireless communication device, which processes the remote location command such that a user of the wireless communication device can locate the device. | 06-13-2013 |
