  • Location-Based Prefetch and Participant-Based Prefetch
    Publication number: 20150181386
    Abstract: To reduce the mobile data usage, information associated with future events is prefetched via an inexpensive mass-data transfer link (e.g., Wi-Fi, Ethernet, or off-peak mobile broadband) and does not need to be fetched via an expensive mobile communication link (e.g., mobile broadband) during normal usage. Location-based prefetch and participant-based prefetch can leverage the existing infrastructures of location-based services (LBS) and social networking services (SNS). Because they provide a more reliable prediction of future events than those guessed from past events, schedule events managed by a calendaring application is primarily used to predict future events.

  • Hybrid Parking Detection
    Publication number: 20150117705
    Abstract: The present invention combines the strengths of the background-subtraction and edge-detection algorithm for parking detection. Being computationally efficient, the background-subtraction algorithm is used whenever possible. On the other hand, being robust, the edge-detection algorithm is used at calibration points, or when the background-subtraction algorithm cannot reliably determine the parking state.

  • Parked vehicle detection based on edge detection
    Patent number: 8923565
    Abstract: The present invention discloses a method for detecting parked vehicles based on edge detection. For each parking space, its boundary comprises an exposed edge, which is not occluded by any parked vehicle. Its primary detected edges are the detected edges that are substantially parallel to the exposed edge. A parking space is detected as occupied if its primary detected edges satisfy at least one of these conditions: (1) their total number is more than a pre-determined minimum number; and/or, (2) their total length is more than a pre-determined minimum length.

  • Discrete three-dimensional memory
    Patent number: 8921991
    Abstract: The present invention discloses a discrete three-dimensional memory (3D-M). It is partitioned into at least two discrete dice: a memory-array die and a peripheral-circuit die.

  • Three-dimensional writable printed memory
    Patent number: 8916938
    Abstract: The present invention discloses a three-dimensional writable printed memory (3D-wP). It comprises at least a printed memory array and a writable memory array.

  • Music-Based Positioning Aided By Dead Reckoning
    Publication number: 20140372027
    Abstract: Music-based positioning (MP) provides positioning service only sporadically and therefore is not suitable for indoor positioning. The present invention discloses system and method for music-based positioning aided by dead reckoning (MP-DR). At each signature burst (i.e. a highly unique short musical segment suitable for positioning), musical sounds are used for positioning. Between signature bursts, positioning is performed by dead reckoning (DR). MP-DR is an ideal combination of MP and DR: DR extends temporal coverage for MP, while MP provides the much needed periodic calibrations for DR.

  • Field-Repair System and Method
    Publication number: 20140359401
    Abstract: The present invention discloses a field-repair system and method for three-dimensional mask-programmed memory (3D-MPROM). Most 3D-MPROM data are not checked in factory, but checked and repaired in field. The field-repair system comprises a playback device with a communicating means. Once the playback device detects bad data from the 3D-MPROM, it uses the communicating means to fetch good data to replace the bad data from a remote server, which stores at least a correct copy of the 3D-MPROM data.

    Publication number: 20140358434
    Abstract: The present invention discloses a peer-assisted dead reckoning (PA-DR). When a first mobile device has a much larger location error than a second mobile device, its location can be optimized from that of the second device. For the first device, its optimized location is equal to the sum of the location of the second device and the relative location between two devices.
