Abstract:
The instant disclosure relates to a loudspeaker, which includes a ferrite core, a voice coil, and a movable membrane. The voice coil is wound around the core and cooperatively defining an exciting device. The movable membrane is disposed in close proximity to the exciting device with a gap formed thereinbetween. The loudspeaker constructed without permanent magnets takes up less space and is more cost effective. Thus, the loudspeaker has a broader application range.
Abstract:

The fat-soluble vitamin in the powder compositions is in the form of droplets having an average diameter in the range of about 70 to about 200 nm. Tablets, beverages and beverage concentrates, foods, cosmetics and pharmaceuticals containing the powder composition can be made.
Abstract:
An electronic device with multi-phase mechanism including a host, a storage device and a carriage is provided in the present invention. The storage device is slidably disposed in the host and adapted to be pulled out from the host. The carriage is slidably disposed in the storage device and adapted to be pulled out from the storage device. Through the storage device slidably disposing in the host and being adapted to be pulled out from the host, it facilitates the user to take or replace a content from the storage device. When the carriage is moved out from the storage device in a first phase and then the storage device is pulled out from the host in a second phase, the content in the storage device is taken out.
Abstract:
A knee joint includes a knee member, an upper connecting member that is disposed on top of the knee member for connection with a prosthetic upper leg, a resilient member disposed between the knee member and the upper connecting member, and a connection seat that has an upper portion pivotally connected to the knee member and that has a lower portion for connecting with a prosthetic lower leg.
Abstract:
Methods and compositions for producing a cellular drug release are disclosed. The method comprises: a) providing a composition comprising a therapeutically effective amount of a pharmacological agent adsorbed onto mesoporous hydroxyapatite (HAP) with hydrophobic surfaces; b) exposing the composition to a cell; c) causing entry of the mesoporous HAP into the cell and degradation of the HAP in the lysosomes of the cell and desorption of the agent from the mesoporous HAP; d) causing release of the desorbed agent from the lysosomes into the cytoplasm of the cell; and e) causing release of the desorbed agent to outside the cell. The composition comprises a) mesoporous HAP with hydrophobic surfaces; and b) a therapeutically effective amount of a pharmacological agent, adsorbed onto the hydrophobic surfaces of the mesoporous. HAP. The composition is characterized in that it constantly releases the agent in vivo for a period of at least 4 weeks.

Abstract:
A heat-dissipating module for use in an electric device includes a circuit board, at least one heat-generating element, and at least one heat-conducting element. The circuit board has a first surface, a second surface and at least one perforation. The heat-conducting element is disposed in the perforation. The heat-conducting element includes a base and a sidewall. The heat-generating element is disposed on the base or the sidewall of the heat-conducting element so that the heat by the heat-generating element is conducted to the second surface of the circuit board through the heat-conducting element.

Abstract:
A portable communication device includes an appearance, a substrate and a switchable resonant antenna. The substrate is disposed in the appearance, and the substrate has a ground plane. The switchable resonant antenna comprises a first connection portion, a switching unit, a first metal element and a second metal element, where the first connection portion is electrically coupled between the ground plane and the switching unit, the switching unit is configured to electrically couple the first connection portion to the first metal element or the second metal element according to a control signal generated corresponding to a detecting result, in order to generate a first resonant mode.
Abstract:
An improved structure of a lift cover connector includes a base, a cover, a main body, a terminal module and a plurality of positioning members. The cover is rotatably pivoted to one end of the base, and the cover can be opened or closed relative to the base. The terminal module is received in the base, and is inserted and positioned in the main body. The base and the main body are engaged with each other, and the positioning members are inserted in the main body. This design enables the cover to automatically close the base in a normal state by a resilient function of the positioning members, thereby to facilitating reducing product loss and improving the overall yield.
