316 results about "Dash" patented technology

The dash is a punctuation mark that is similar in appearance to the hyphen and minus sign but differs from these symbols in length and, in some fonts, height above the baseline. The most common versions of the dash are the en dash (–), longer than a hyphen; the em dash (—), longer than the en dash; and the horizontal bar (―), whose length varies across typefaces but tends to be between those of the en and em dashes.

Dynamic adaptive code rate selection method based on MPEG-DASH (MPEG-Dynamic Adaptive Streaming over HTTP) protocol

The invention discloses a dynamic adaptive code rate selection method based on a MPEG-DASH (MPEG-Dynamic Adaptive Streaming over HTTP) protocol. The dynamic adaptive code rate selection method comprises the steps of: firstly, establishing a HTTP connection between a server and a client; by the client, sending a HTTP Get request to the server, requesting to download a MPD file and storing the MPD file; after the server receives the request of the client, by the server, responding to the client and sending the MPD file, and by the client, downloading the MPD file and parsing the downloaded MPD file; according to an URL address obtained by parsing the MPD file, firstly downloading one part of a slice at the minimum code rate, placing the slice into a cache region, carrying out calculation, statistics and recording on a network bandwidth when the video slice is downloaded, and predicting a network bandwidth when a next video slice is downloaded; and by combining a current residue condition of video slices of the cache region, selecting a code rate for downloading the next video slice until the end. An effect of improving video quality to the greatest extent in the premise of smoothly carrying out playing is achieved, and viewing experience of a user is greatly enhanced.

Apparatus for deploying an air bag through a hard panel

An apparatus for deploying an air bag through an automotive dash panel (12) includes an air bag door (16) integrally formed in the panel and defined by a door perimeter including a frangible edge (18) of reduced cross section. A dispenser (20) supports the air bag (24) behind the door. A metal reaction plate (28) is positioned between the air bag (24) and the door (16). When the air bag inflates, it forces the reaction plate (28) to bend around a horizontal hinge line (36). As the reaction, plate pivots it concentrates inflation force along a lower portion of the frangible door edge. This helps to predictably separate the door from the dash panel by tearing along the lower door edge and allowing the tear to propagate up two side edges. In one embodiment, the tear also propagates across an upper edge to completely separate the door from the panel. At least one, and preferably two or three tethers (50) limit how far the door can travel during air bag inflation. A stop member may be included to limit reaction plate bending. After deployment, the reaction plate remains in a position that prevents the door from returning to its original position. A retaining structure may be included to preclude at least a portion of the air bag door from tearing free of the vehicle panel. A hinge (44) may be embedded in the panel in a position spanning a portion of the door perimeter. A hollow channel may be formed into the panel along the frangible marginal edge to create a substantial strength differential with the door perimeter to promote bending along the hinge and/or to help confine tearing to the frangible marginal edge during air bag deployment.
