  • Publication number: 20180359063
    Abstract: Embodiments of methods and apparatuses for resource allocation in a wireless communication system are disclosed. In one embodiment, a method of wireless communication comprises obtaining data to be transmitted over a plurality of sub-channels in a wireless communication environment, determining channel conditions associated with the plurality of sub-channels, scheduling the data to be transmitted according to the channel conditions associated with the plurality of sub-channels to form scheduled data for transmission, and transmitting the scheduled data to one or more receivers via the plurality of sub-channels. The method of determining channel conditions associated with the plurality of sub-channels comprises determining interference observed at each sub-channel in the plurality of sub-channels.

  • Patent number: 9338395
    Abstract: A display allocation method is disclosed herein. The display allocation method is applied to a display in a conference meeting and comprises the following steps: allocating a first, a second and a third image block on the display, in which sizes of the first and the second image block are larger than size of the third image block; detecting an effective sound of a first candidate video corresponding to the third image block to identify whether the first candidate video is effective; setting one of the first and the second image block as a primary image block, and setting another one of the first and the second image block as a secondary image block, in which the secondary image block includes a secondary video; and allocating the first candidate video and the secondary video to the secondary and the third image block respectively if the first candidate video is effective.

  • Patent number: 5501502
    Abstract: A cover for covering a vehicle includes a frame secured to the vehicle and having a flange formed on the upper portion. A number of panels each includes two free ends pivotally coupled to the free ends of the frame and each includes a lower flange for engaging with the flange of the frame. The panels each includes an upper flange for engaging with the lower flange so as to form a nested group of arch shaped configuration for covering and for protecting the vehicle. The panels may be rotated by a motor and may form an anti-theft device for the vehicles.

  • Patent number: 5395154
    Abstract: A foldable baby chair comprising a chair back, a chair seat pivotally connected to the chair back via a pivot assembly. The pivot assembly consists of a salient part, a recess part suitable for interfittingly engaging with the salient part, and a positioning assembly, allowing the chair back to be pivot relative to the chair seat and then positioned at a desired inclination by means of the positioning assembly. Substantially inverted U-shaped guard rails are separately connected to the chair back and the chair seat by means of pivot assemblies, so that the inverted U-shaped guard rails are allowed to pivot relative to the chair back or chair seat and can be positioned to different inclinations. Extensible and foldable handle, visor, and footrest can be pivotly connected to the chair back and chair seat, thereby allowing the baby chair to be otherwise used as a baby cart, carry-cot, carryall, suitcase, dining chair, rocking chair, etc.
