Abstract:
Systems and methods for determining that a maximum number of IP sessions have been established are provided. There are instances when the mobile device transmits a request to the wireless network. According to an aspect, in the event that the maximum number of IP sessions is already established for the mobile device, the wireless network transmits a response indicating that the request cannot be fulfilled. The mobile device determines based on the response that the maximum number of IP sessions is already established, which allows the mobile device to determine the maximum number of IP sessions that can be supported so that IP sessions can be managed accordingly.
Abstract:
A cellular communications system may include at least one base station selectively denying attempts to establish wireless communications links therewith, and wirelessly transmitting denial messages for denied attempts. The system may further include at least one mobile cellular communications device including a wireless transceiver and a controller cooperating therewith for attempting to establish a wireless communications link with the at least one base station having a quality of service (QoS) level associated therewith. If a denial message is received, the controller continues to attempt to establish the wireless communications link at a first attempt rate. Yet, if the wireless communications link cannot be established with the desired QoS level, and if no denial message is received, then the controller continues to attempt to establish the wireless communications link at a second attempt rate different than the first attempt rate.
Abstract:
The present invention relates to transmit apodization using a sinc function in an ultrasound system. The ultrasound system includes: a transmission unit operable to generate transmit pulse signals with transmit apodization applied by using a sinc function; a probe operable to generate ultrasound signals based on the transmit pulse signals to thereby form a transmit beam and transmit the transmit beam along a predetermined scan line among a plurality of scan lines in a target object, the probe being further operable to receive ultrasound echoes reflected from the target object; and a reception unit operable to form receive signals corresponding to a plurality of scan lines based on the ultrasound echoes.
Abstract:
A television comprising: a television screen for displaying video signals to a user; a network interface for accessing a packet-based network; processing apparatus coupled to the television screen and network interface, arranged to execute a communication client application for receiving communication events via the network interface and packet-based network; power-saving circuitry coupled to the television screen and processing apparatus, configured to switch between a higher-power mode in which the television screen is switched on and a lower-power mode in which the television screen is switched off; and a user input device communicable with the power-saving circuitry for switching between the power modes, the lower-power mode thus being a mode set in response to a manual user input from the user input device. The client continues to monitor the network interface during the low power mode in order to provide notifications and/or wake up the television.
Abstract:
A method of optimizing reconnection of a point to point protocol link layer in a mobile device comprising the steps of: monitoring whether the mobile device has entered a new zone; starting a stabilization period when the mobile device enters a new zone; checking whether the mobile device enters a different zone during the stabilization period; if the mobile device enters a different zone during the stabilization period, restarting the stabilization period and performing the checking step; and if the mobile device does not enter a new zone during the stabilization period, determining whether the mobile device is in a new zone, reconnecting to the new zone if the mobile device is in the new zone, and otherwise performing no reconnection.
Abstract:
A system and method of notifying a user of events in a customizable manner during and not during a voice call is provided. According to one aspect, the notifications are configurable to be dependant on whether or not there is an active voice call. Notifications may also be configured to be different depending on whether or not the wireless device is inside a device holster. Notifications can be configured to be different for different events so that the user may be able to associate certain notifications with certain events. The user can also configure the type of events that trigger notification. Notifications include any combination of audible cues, visual cues, and vibration cues.
Abstract:
A system (100) that determines exposure based on local conditions is disclosed. The system can include a sensor (172) configured to sense local conditions local to a user of the system, a sensor local wireless transmitter (174) coupled to the sensor, and an electronic device (105). The electronic device can include a controller (120) configured to control operations of the electronic device, a device local wireless transceiver (155) coupled to the controller and wirelessly coupled to the sensor local wireless transmitter, a network interface coupled (150) to a wide area network and coupled to the controller, the network interface configured to obtain local environmental conditions, and an exposure module (190) coupled to the controller. The exposure module can determine exposure to an environmental element based at least on the local conditions sensed by the sensor and the local environmental conditions obtained by the network interface.
Abstract:
A touch sensitive display for an electronic device includes a display (201) for presenting information to a user and at least four infrared transceivers (202,203,204,205) disposed about the display (201). The four or more infrared transceivers (202,203,204,205) can be disposed about the display (201) such that infrared light (206,207,208,209) from each of the infrared transceivers (202,203,204,205) projects across a surface (303) of the display (201). A controller (214), which is operable with the infrared transceivers (202,203,204,205), is configured to detect which of the infrared transceivers (202,203,204,205) has the most reflected signal (702). The controller (214) can then correlate this and other information with one of a plurality of user modes of operation. A control menu (802) can then be presented on the display (301) in accordance with the user mode of operation to mitigate finger blockage.
Abstract:
A method and system for channel tracking in an adaptive equalizer for a digital data receiver. The method includes determining a first set of tap weights and a second set of tap weights of the equalizer, and determining a difference between the first and second sets of tap weights. The method also includes determining an error estimate based on symbols received at the receiver, comparing the error estimate with a divergence threshold, and determining a step size factor based on the difference and the comparison.
