摘要:
A foldable support for supporting a portable computing device includes a main frame, a back plate, and a hinge assembly connecting the back plate to the main frame, the hinge assembly being able to position and lock the back plate in a desired position with respect to the main frame. A base member is rotatably connected to a bottom of the main frame. When the portable computing device is supported by the foldable support, a back of the portable computing device rests against the main frame, and a bottom of the portable computing device rests on the base member.

A support structure includes a base, a pair of stands, a top hinge, and a pair of holding arms. The stands are rotatably connected to one end of the base to support the base. The top hinge is rotatably connected to the other end of the base opposite to the stands. The rotation plane of the top hinge is perpendicular to the rotation plane of the stands. The holding arms are rotatably connected to the top hinge for holding an object at any desired angle.

This invention presents a multimode xDSL line card adaptive activation method, comprising the following steps: A) A master controller is installed and configured with multiple templates based on the modes of operation supported by a line card, and forwards templates to said line card; B) The line card receives templates forwarded by the master controller and activates the line card communications chip; C) The communications chip communicates with the remote CPE and decides on a mode of operation according to a handshake protocol; D) The line card employs a corresponding template according to the mode of operation chosen in Step C, and practices circuit activation with the CPE. This invention solves the existing problems in current multimode xDSL technology of poor compatibility and inability to adapt effectively.

The present invention discloses a system for testing subscriber lines and method thereof. The system includes a broadband line testing control module and a remote terminal subscriber access control module located at a subscriber line that is located between the broadband line testing control module and a remote terminal unit. The broadband line testing control module sends a signal of disconnecting the subscriber line to the remote terminal subscriber access control module, and tests the subscriber line. The remote terminal subscriber access control module receives said signal from the broadband line testing control module, and controls the remote terminal unit to disconnect from or connect to the subscriber line based on said signal. With the system and method according to the present invention, not only the precision of subscriber line testing is guaranteed, but also the subscriber lines can be periodically tested without manual operation.
摘要:
A power source (212) is disclosed for charging a battery (330) within a portable electronic device (310). An apparatus (422), such as a photovoltaic or thermoelectric cell, for charging the battery (330) is disposed contiguous to and within a transparent housing (412) of the portable electronic device (310). A fluorescent species (416), such as quantum dots or a fluorescent dye, is disposed on a side of the housing (412) opposed to the apparatus (422). Light (430) striking the fluorescent species (416) is converted into photons (432, 434) having a narrower spectrum that passes through the housing (412) to the apparatus (422). An optional layer (418) may be disposed on the fluorescent species (416) that reflects light from the fluorescent species (416) to the apparatus (422). Photonic crystals (415) may be combined with the fluorescent species (416) to increase reflectivity.

Semiconductor structures and processes for fabricating semiconductor structures comprising hafnium oxide layers modified with lanthanum oxide or a lanthanide-series metal oxide are provided. A semiconductor structure in accordance with an embodiment of the invention comprises an amorphous layer of hafnium oxide overlying a substrate. A lanthanum-containing dopant or a lanthanide-series metal-containing dopant is comprised within the amorphous layer of hafnium oxide. The process comprises growing an amorphous layer of hafnium oxide overlying a substrate. The amorphous layer of hafnium oxide is doped with a dopant having the chemical formulation LnOx, where Ln is lanthanum, a lanthanide-series metal, or a combination thereof, and X is any number greater than zero. The doping step may be performed during or after growth of the amorphous layer of hafnium oxide.

The invention is based, in part, on the discovery that the addition of cations, such as calcium or magnesium ions, to muscle tissue before solubilization of the muscle proteins enhances removal of membranes, which reduces oxidation and spoilage of the muscle tissue.
摘要:
High quality monocrystalline metal oxide layers are grown on a monocrystalline substrate such as a silicon wafer. The monocrystalline metal oxide is grown on the silicon substrate at a temperature low enough to prevent deleterious and simultaneous oxidation of the silicon substrate. After a layer of 1-3 monolayers of the monocrystalline oxide is grown, the growth is stopped and the crystal quality of that layer is improved by a higher temperature anneal. Following the anneal, the thickness of the layer can be increased by restarting the low temperature growth. An amorphous silicon oxide layer can be grown at the interface between the monocrystalline metal oxide layer and the silicon substrate after the thickness of the monocrystalline oxide reaches a few monolayers.
