  • Patent number: 10154470
    Abstract: Techniques for supporting a control plane solution for location services and positioning are described. In an aspect, an Evolved Serving Mobile Location Center (E-SMLC) may communicate with a Mobility Management Entity (MME) to support location services and positioning for a UE. In one design, the E-SMLC may receive a location request from the MME, perform a positioning procedure with the UE in response to the location request, and send a location response to the MME after completing the positioning procedure. For a UE-assisted or UE-based positioning procedure, the E-SMLC may send a downlink positioning message to the UE via the MME and may receive an uplink positioning message from the UE via the MME. For a network-based positioning procedure, the E-SMLC may send a network positioning request message to an eNB via the MME and may receive a network positioning response message from the eNB via the MME.

  • Patent number: 10154514
    Abstract: A user equipment (UE) may transmit a UE-generated uplink message to a base station to request resources for an uplink transmission. The UE may be configured to send the message (e.g., a scheduling request (SR)) using different transmission modes. For example, the UE may transmit the SR using a scheduled mode where the UE conveys the SR along with another uplink message (e.g., a control message). In some examples, the UE may transmit the SR using an autonomous mode where the UE transmits the SR in resources reserved for SR transmissions. The UE may determine which transmission mode to use based on certain characteristics of the SR or the data associated with the SR.

  • Patent number: 10152101
    Abstract: Systems and methods relate to controlling voltage deviations in processing systems. A scheduler receives transactions and to be issued for execution in a pipeline. A voltage deviation that will occur if a particular transaction is executed in the pipeline is estimated before the transaction is issued. Threshold comparators are used to determine if the estimated voltage deviation will exceed specified thresholds to cause voltage overshoots or undershoots. The scheduler is configured to implement one or more corrective measures, such as increasing or decreasing energy in the pipeline, to mitigate possible voltage overshoots or undershoots, before the transaction is issued to be executed in the pipeline.

  • Patent number: 10154591
    Abstract: Passive device assembly for accurate ground plane control is disclosed. A passive device assembly includes a device substrate conductively coupled to a ground plane separation control substrate. A passive device disposed on a lower surface of the device substrate is separated from an embedded ground plane mounted on a lower surface of the ground plane separation control substrate by a separation distance. The separation distance is accurately controlled to minimize undesirable interference that may occur to the passive device. The separation distance is provided inside the passive device assembly. Conductive mounting pads are disposed on the lower surface of the ground plane separation control substrate to support accurate alignment of the passive device assembly on a circuit board. By providing sufficient separation distance inside the passive device assembly, the passive device assembly can be precisely mounted onto any circuit board regardless of specific design and layout of the circuit board.

  • Patent number: 10154461
    Abstract: A personal identification device may conserve power by delegating one or more operations to another device. For example, the one or more operations may be associated with the authentication of the personal identification device. In one example, the personal identification device may determine an amount of power greater than a power threshold will be consumed by the personal identification device to perform the one or more operations. The personal identification device may determine it can communicate with a mobile device that is capable of performing the one or more operations, and may then delegate the one or more operations to the mobile device to conserve power. In one example, the personal identification device may receive the results of the one or more operations from the mobile device, and may provide data associated with the results to a personal identification device detector for authentication of the personal identification device.

  • Patent number: 10152261
    Abstract: Providing memory bandwidth compression using compression indicator (CI) hint directories in a central processing unit (CPU)-based system is disclosed. In this regard, a compressed memory controller provides multiple CI hint directory entries, each providing a plurality of CI hints. The compressed memory controller receives a memory write request comprising write data, determines a compression pattern for the write data, and generates a CI for the write data based on the compression pattern. The compressed memory controller writes the write data to the memory line, and writes the generated CI into one or more ECC bits of the memory line. In parallel, the compressed memory controller determines whether the physical address corresponds to a CI hint directory entry, and, if so, a CI hint of the CI hint directory entry corresponding to the physical address is updated based on the generated CI.

  • Patent number: 10152495
    Abstract: A method, an apparatus, and a computer program product conduct online visual searches through an augmented reality (AR) device having an optical see-through head mounted display (HMD). An apparatus identifies a portion of an object in a field of view of the HMD based on user interaction with the HMD. The portion includes searchable content, such as a barcode. The user interaction may be an eye gaze or a gesture. A user interaction point in relation to the HMD screen is tracked to locate a region of the object that includes the portion and the portion is detected within the region. The apparatus captures an image of the portion. The identified portion of the object does not encompass the entirety of the object. Accordingly, the size of the image is less than the size of the object in the field of view. The apparatus transmits the image to a visual search engine.
