An exemplary electronic device with a speaker includes a mounting plate, a speaker mounted on the mounting plate, two fasteners mounting the speaker, and a buffer washer squeezed between the mounting plate and the speaker. The buffer washer is capable of absorbing vibration of the speaker. Each of the fasteners includes a head portion and a post portion. The post portion is mounted on the mounting plate and is located outside the speaker. The head portion presses the speaker to abut against the buffer washer.

A new class of photoactivatable dyes provides the ability to study cell-cell communication in live animals non-invasively with high spatiotemporal resolution. The compositions are made up of a macromolecule, a caging group, and a coumarin dye. Upon photolysis, the coumarin dye is released from the macromolecule caging group complex and is freely diffusible in cells and between cells. The compositions are retained in cells very well, having no observable side effects, no susceptibility to metabolism, and the ability to generate bright fluorescence signals after photolysis. Because of their high loading capacity and long cellular retention, they can be selectively uncaged in specific cells.

A method and a system for producing synthetic gas from biomass by high temperature gasification, including: feeding raw material, carbonizing, pulverizing the charcoal, and transporting charcoal powder to the gasification furnace for gasification. A heat source for the carbonizing is achieved by a direct combustion reaction between external combustible gas and external oxygen in a carbonization furnace. The heat emitted from the reaction being directly provided to the necessary heat of biomass pyrolysis, and yielding pyrolysis gas and charcoal from carbonization furnace.

Embodiments of a computer system, a method, an integrated circuit and a computer-program product (i.e., software) for use with the computer system are described. These devices and techniques may be used to analyze an electrical characteristic of a logic gate electrically coupled to an output network in a stage. In particular, during the analysis, the effective capacitance of an output network coupled to a logic gate is approximated as a function of a total resistance of the output network, a total capacitance of the output network, and a geometric parameter of the output network. Using the effective capacitance and other parameters, such as a slew rate of an electrical signal applied to an input of the logic gate, an electrical characteristic of the logic gate, such as an input capacitance, is determined.

An optical disc player includes a main body, a lid, a rotator, and a protective structure. The lid is pivotably connected to the main body. The rotator is disposed in the main body for rotating discs and can be covered by the lid. The protective structure is disposed between the rotator and the lid. The protective structure is capable of suppressing noise and/or damage caused by contact between the rotator and the lid when the rotator operates.
摘要:
The present invention relates to fiber glass strands, yarns, fabrics, composites, prepregs, laminates, fiber-metal laminates, and other products incorporating glass fibers formed from glass compositions. The glass fibers, in some embodiments, are incorporated into composites that can be used in reinforcement applications. Glass fibers formed from some embodiments of the glass compositions can have certain desirable properties that can include, for example, desirable electrical properties (e.g. low Dk) or desirable mechanical properties (e.g., specific strength).
