Abstract:
A haptic feedback apparatus includes a screen and a piezoelectric vibrator partially connected with the screen. The screen comprises a display viewing area and a frame surrounding the display viewing area. The piezoelectric vibrator engaged with the screen defines a moving portion having a projecting portion extending from one distal end of the moving portion toward the screen. Wherein, the screen defines a cavity and the projecting portion of the piezoelectric vibrator is at least partially accommodated in the cavity. The manufacture of the haptic feedback apparatus is simple and low-cost.

Abstract:
A smooth streaming system provides a stateless protocol between a client and server in which the server embeds incremental control information in media fragments. The server provides uniform media fragment responses to media fragment requests that are cacheable by existing Internet cache infrastructure. The smooth streaming system receives media data in fragments from one or more encoders, creates an index of each fragment, and stores the fragments. The server provides fragments to clients that contain metadata information describing the encodings available on the server and the encoding of the fragment. The server may also provide information within each fragment that allows the client to determine whether the client is requesting data too fast or too slow, so that the client can adapt its request rate to a cadence in tune with the rate at which the server is receiving encoder data.
Abstract:
An adaptive streaming system is described herein that provides a stateless connection between the client and server for streaming media playback in which the data is formatted in a manner that allows the client to make decisions and react more quickly to changing network conditions. The client requests uniform chunks of media from the server that include a portion of the media. The adaptive streaming system requests portions of a media file or of a live streaming event in small-sized chunks each having a distinguished URL. This allows streaming media data to be cached by existing Internet cache infrastructure. Each chunk contains metadata information that describes the encoding of the chunk and media content for playback by the client. The server may provide chunks in multiple encodings so that the client can switch quickly to chunks of a different bit rate or playback speed.
Abstract:
A glass substrate with multiple identical microarrays is provided, for example, for the identification of genes via nucleic acid hybridization. The multiarray substrate permits the analysis, in parallel, of several different samples on the same substrate and thus under the same conditions. Results obtained using the multiarray substrate are therefore less variable than those obtained with conventional techniques.
Abstract:
Cell-specific methods for silencing genes using double-strand inhibitory RNA (iRNA) are provided, as are constructs for carrying out the methods.
Abstract:
A speaker and a speaker-box using the same is provided in the present disclosure. The speaker includes a basket and a vibration system. The vibration system includes a diaphragm fixedly connected to the basket. The diaphragm includes a body part and a fixed part bent and extended from the edge of the body part to the basket, the basket includes a side wall encircling the receiving space, the side wall includes an upper surface opposite to the body part and an outer side surface extended from the outer edge of the upper surface, and the upper surface encircles an opening communicated with the receiving space; the body part covers the opening and is fixed with the upper surface, and the fixed part is extended along the outer side surface and fixed with the outer side surface.
Abstract:
A sparse streaming system provides a first-class means for sparse metadata to be added to streaming media presentations and to be delivered using an integrated data channel that is cacheable using readily available HTTP-based Internet caching infrastructure for increased scalability. The sparse streaming system stores a reference to a sparse track within a continuous track. If a continuous fragment arrives at the client that refers to a sparse fragment that the client has not yet retrieved, then the client requests the sparse fragment. In addition, each sparse fragment may include a backwards reference to the sparse fragment created immediately prior. The references in the continuous fragments make the client aware of new sparse track fragments, and the backwards references in the sparse track fragments ensure that the client has not missed any intervening sparse track fragments.
Abstract:
Disclosed is piezoelectric vibrator including a piezoelectric vibrator unit. The piezoelectric vibrator has a vibrating portion, a mass attached on the vibrating portion and having an connecting portion attached on the vibrating portion and at least one extending portion extending from the connecting portion and away from the vibrating portion, and a holder having a stopping portion disposed between the extending portion of the mass and the vibrating portion. A distance from the extending portion to the at least one stopping portion is less than the amplitude of the vibration portion for limiting the vibrating portion and avoiding excessive amplitude of the vibrating portion.
Abstract:
A vibration speaker is disclosed. The vibration speaker includes: a display screen including a first surface and a second surface opposite to the first surface; a vibrator disposed below the display screen with vibration direction perpendicular to the display screen; a cover including a lower cover and an upper cover assembled with the lower cover for forming a receiving space to receive the display screen and the vibrator; an elastic member comprising an inner end attached to the display screen, an outer end disposed between the lower cover and the upper cover, and a connecting part disposed between the inner end and the outer end and concaved towards the lower cover; wherein the display screen is actuated to vibrate and generate sound by the vibration of the vibrator.
