A method for annotating dynamic content includes receiving a freeform annotation overlaid on dynamic content; determining whether the dynamic content changes; in response to a determination that the dynamic content changes, displaying an indicator corresponding to a region where the freeform annotation was created; determining whether the indicator is selected; in response to a determination that the indicator is selected, displaying a lightbox with the freeform annotation as it was overlaid on the dynamic content when it was created; determining whether the a revert button included in the lightbox is selected; and in response to a determination that the revert button is selected, displaying the freeform annotation overlaid on the dynamic content as it was created before the dynamic content changed.

Reflowable content with annotations

A computing device includes a housing and a display assembly having a screen. The housing at least partially circumvents the screen so that the screen is viewable and a set of touch sensors are provided with the display assembly. A processor is provided within the housing to detect a gesture via the set of touch sensors, and to interpret the gesture as one of a plurality of user inputs. The processor further detects a presence of extraneous objects on a surface the screen of the display assembly, and adjusts one or more settings of the computing device in response to detecting the presence of extraneous objects. For example, the processor may adjust the one or more settings by reconfiguring a set of actions to be performed in response to the plurality of user inputs.

Method and system for mobile device splash mode operation and transition thereto

The present invention provides a method and system for mitigating fading and/or poor reception at a receiver. The receiver includes configurations each of which can provide different reception characteristics. The receiver evaluates the reception quality of the radio signal with the antenna in a first configuration and with the antenna in at least a second configuration and selects the antenna configuration that has the best evaluated reception for use until a subsequent iteration, when the process is repeated. The antenna configurations can correspond to configurations wherein reception is favored in different directions or to configurations wherein different antennas are selected, each antenna being spaced from each other antenna. The method can also improve the reception of a signal transmitted by selecting an antenna configuration for transmissions which provides improved reception quality at the destination receiver.

A data communication method for puncturing of parity bits defining all parity data for a minimum code rate generated by an encoder is disclosed. The method initializes an accumulator associated with the parity bits to an initial value, and for each parity bit increments the accumulator by a increment value and determines if the accumulator has overflowed. If the accumulator overflows, at least one of the parity bits is selected for transmission.

Hybrid automatic repeat request system and method

A data channel to transmit data from a transmitter to one or more of a plurality of receivers, each of which intermittently reports to the transmitter its reception quality of signals transmitted by the transmitter. The transmitter transmits the data in frames which include at least one block. Each block includes the same predefined number of traffic symbols, and includes a header portion and a payload portion. The header portion of each block is packaged for transmission in a robust manner, enhancing the probability that each receiver will be able to recover it and the header portion includes information required to recover the payload portion. The payload portion is, in accordance with the reception quality reported by the intended receiver, packaged to make efficient use of the transmission resources while ensuring a reasonable probability that the intended receiver will be able to recover the payload. The header portion can include indications of the modulation, forward error correction and repetition utilized to package the payload and can indicate the length of the payload.

Quality dependent data communications channel

A system and method of determining the maximum uplink transmit power of a subscriber station from a remote base station where the subscriber station reports incidents of foldback in its radio to the base station. When the base station receives the report, it reduces the maximum uplink transmit power of the subscriber station. After a period of time lapses without any reports of foldback occurring, the base station increases the maximum uplink transmit power of the subscriber station.

System and method for managing available uplink transmit power

An apparatus, system and method for improving the SNR of a desired signal received at a receiver in a multiple access communication system is disclosed. The apparatus, system and method subtracts known or knowable signals from the total signal received at the receiver and the desired signal is then determined from the result of the subtraction. The known, or knowable, signals can be synchronization signals or other interfering channel signals transmitted by the transmitter, such as a wireless network base station, serving the receiver, such as a subscriber station in such a wireless network, and/or can be such signals transmitted by another transmitter, such as an adjacent base station, or an adjacent sector in multi-sector systems.

Method, system and apparatus for improving reception in multiple access communication systems

A novel communication channel structure and method in a wireless communication system is provided. In an embodiment of the invention, the communication system includes a base station and a plurality of subscriber stations and the subscriber stations are given access to a variety of channels, including at least one uplink data channel. The uplink data channel can operate in at least a random access mode and a polled access mode. The base station informs each subscriber station it serves of the current mode of the uplink channel via an associated downlink signaling channel and, in random access mode, each subscriber station is able to randomly access the shared uplink channel. In polled mode, each subscriber station waits for permission from the base station before sending data over the shared uplink channel. A method of operating the system monitors the collisions which occur on the uplink channel in random mode and/or the amount of data and/or the data's priority level and/or QoS requirements and switches the system between random and polled modes as appropriate. In polled mode, the method determines which subscriber stations should access the uplink and when.

Communication channel structure and method

The present invention provides a novel system, method and apparatus for allocating power between at least two communication services that share a common power output limit. Two communication services particularly suited for the present invention are voice services and data services transmitted on the downlink of a wireless network. An embodiment of the method includes determining the actual consumption of power on the voice channels of the wireless network during a given time period, and allocating substantially the same amount of power to the voice channels for the next time period, thus allowing for the allocation of the remaining amount of power to the data services, and thereby allowing, for example, increased modulation of the data services and thereby improve overall rates of data transfer and/or reliability of data transmission.

Quality dependent data communication channel

A system for transmitting data between stations, such as base stations and subscriber stations in a wireless telecommunications system, employs variable set of interleaving parameters for its interleaving operations. By using different set of interleaving parameters with the interleavers, data which would otherwise be aligned when transmitted from a station to many stations, or from many stations to a station, will not be aligned after interleaving has been performed. This reduces the peak to average ratio required for a transmitter and/or can reduce interference experienced at receivers in the system. This is especially true if a significant proportion of the otherwise aligned signals are symbols which require zero energy to transmit.

Method, system and apparatus for transmitting interleaved data between stations

A user control channel for a wireless digital subscriber line systems and the like, or other communications systems which can benefit from a control channel which provides a low data rate connection between stations on an ongoing basis, makes efficient use of transmission capacity in the communications systems. In one embodiment, the user control channel has a structure employing slotted frames, and a user can be assigned multiple slots, a single slot or less than a single slot (sharing slots with other users) to meet the data transmission needs of the user. Also, one or more slots can be designated as random access slots which users can access via an Aloha-like or other random access protocol as needed.
