Abstract: Apparatuses (devices, systems) and methods for shielding (protecting) surroundings around periphery of regions of interest located inside objects (e.g., patients) from radiation emitted by X-ray systems towards the objects. Apparatus includes: at least one radiation shield assembly including a support base connectable to an X-ray system radiation source or detector, and a plurality of radiation shield segments sequentially positioned relative to the support base, thereby forming a contiguous radiopaque screen configured for spanning around the region of interest periphery with a radiopaque screen edge opposing the object. Radiation shield segments are individually, actively controllable to extend or contract to selected lengths with respective free ends in directions away from or towards the support base(s), for locally changing contour of the radiopaque screen edge.

Abstract: A base station that controls carrier aggregation for a user equipment (UE) includes a memory configured to store weight factors for serving cells that are aggregated to provide wireless connectivity to the UE. The weight factors are determined based on characteristics of the serving cells. In some cases, the weight factors are determined based on frequencies of carriers used by the serving cells to provide the wireless connectivity to the UE. The base station also includes a processor configured to determine, based on the weight factors and a total weight assigned to the UE, weights for transmitting data to the UE via the serving cells. The base station further includes a transceiver configured to transmit data to the UE via the serving cells at priorities that are determined based on the weights for the serving cells.

Abstract: Methods and systems are described herein for generating dynamic conversational responses. Conversational responses include communications between a user and a system that may maintain a conversational tone, cadence, or speech pattern similar to a human during an interactive exchange between the user and the system. The interactive exchange may include the system responding to one or more user actions (which may include user inactions), and/or predicting responses prior to receiving a user action.

Abstract: A base station that controls carrier aggregation for a user equipment (UE) includes a memory configured to store weight factors for serving cells that are aggregated to provide wireless connectivity to the UE. The weight factors are determined based on characteristics of the serving cells. In some cases, the weight factors are determined based on frequencies of carriers used by the serving cells to provide the wireless connectivity to the UE. The base station also includes a processor configured to determine, based on the weight factors and a total weight assigned to the UE, weights for transmitting data to the UE via the serving cells. The base station further includes a transceiver configured to transmit data to the UE via the serving cells at priorities that are determined based on the weights for the serving cells.

Abstract: In a cell where messages having a message type are sent without knowledge of radio frequency conditions for individual ones of user equipment within the cell, measured radio frequency conditions are accessed of multiple user equipment within the cell. Based on the measured radio frequency conditions, a minimum control channel coding rate is determined for a control channel for messages having the message type. Subsequent to a determination of the minimum control channel coding rate, transmission is caused toward all user equipment in the cell of the messages having the message type using the determined minimum control channel coding rate for the control channel. Methods, apparatus, computer programs, and program products are disclosed. The methods may be performed by a base station, self-organizing network server, or other apparatus.

Abstract: A method and apparatus may predict a link quality. The method may also include determining a primary cell for a user equipment based on the predicted link quality. The determining the primary cell comprises determining whether the user equipment should be served by a time-division-duplex carrier or by a frequency-division-duplex carrier. The method may also include determining a carrier aggregation to be used by the user equipment based on the predicted link quality.

Abstract: A method of optimizing use of a plurality of high-rate packet data (HRPD) resources may include assigning one of the plurality of HRPD resources to each of a plurality of mobile stations that is coupled to a radio access network, where the one of the plurality of HRPD resources is used to establish one of a plurality of HRPD sessions between one of the plurality of mobile stations and a radio access network, and where each of the plurality of mobile stations is not using packet-switched data channel. Subsequently an additional mobile station wirelessly coupling to the radio access network and requesting an HRPD resource. A first HRPD resource is reassigned to the additional mobile station without notifying the first mobile station, where the first HRPD resource is used to establish an additional HRPD session between the additional mobile station and the radio access network.

Abstract: A method and apparatus of managing an active set of a mobile station in a soft-handoff environment includes for a reverse link, comparing a reverse link quality metric to a reverse link quality threshold, where the reverse link is associated with a base station in the active set, and determining an aggregate reverse link quality metric corresponding to at least one base station that is a member of the active set but is not under consideration to be dropped from the active set. If the reverse link quality metric is below the reverse link quality threshold for a time period, the aggregate reverse link quality metric is compared to an aggregate reverse link quality threshold, and if the aggregate reverse link quality metric compares favorably to the aggregate reverse link quality threshold, the base station is removed from the active set.
