Abstract:
Methods and systems for fast variable block-size motion estimation based on merging and splitting procedures for AVC video encoding are disclosed. The methods take advantage of the correlation of the Motion Vectors (MVs) of the different block-size modes to achieve a good computation reduction. Considering that the smaller the block-size difference between two block-sizes is, the more correlations between their MVs can be expected, the methods use a 8*8 block as an initial processing block to calculate prediction MVs. The prediction MVs are then used in predicting MVs for other block-sizes.
Abstract:
A light guide plate and method for fabricating the same are proposed. An injection molding process is performed to form at least an arc-shaped first opening portion on the light guide plate, so that a concave lens structure is formed on an edge of the first opening portion to be in line with a light source. By such arrangement, the concave lens structure can direct light and achieve a uniform light dispersion effect.
Abstract:
A combination modem including at least one line connector that is configured for coupling to a transmission medium, analog modem logic that is capable of performing analog modem communications via the transmission medium, digital modem logic that is capable of performing digital modem communications via the transmission medium, a bus interface that enables communication with a computer via an expansion bus of the computer, and processing logic. In this manner a single modem expansion card supports both analog and digital modem technologies using only one slot of an expansion bus of the computer. The analog modem logic may support 56K technologies, such as K56Flex™, V.90, etc., or any combination thereof. The digital modem logic may be according to any type of xDSL, such as ADSL, or U-ADSL, etc. The modem may operate as an analog modem, a digital modem, or as both at the same time with or without a POTS splitter. A single digital signal processor (DSP) located on the modem card may be used to support either the analog or the digital modem communications at any given time or both at the same time. The modem card may be configured as a PCI card for plugging into a PCI bus of the computer.
Abstract:
An interface for personal communications systems is described which provides rapid identification of a caller and limited access based on a variety of parameters obtained from caller identification information encoded by the telephone company. The incoming telephone call information is compared to a preprogrammed access matrix to determine if the caller is authorized to access the personal communications system connected to the interface. A telephone call screening method and apparatus which incorporates the encoded caller identification is also described.
Abstract:
A variable-length decoder is disclosed in which a received variable-word-length encoded bit stream is input to a buffer (102) and read out in parallel sequences equal in length to the maximum length codeword. These sequences are read into cascaded latches (105, 107). The cascaded sequences in both latches are input to a barrel shifter (109) which provides from its multi-bit input, a sliding decoding window to a table-lookup memory device (112). A control signal directly shifts the position of the decoding window of the barrel shifter as each codeword is detected. To detect each codeword, the initial bits in the decoding window are compared with the codeword entries in the table-lookup memory. When a codeword is detected, the corresponding stored codeword length is accumulated (120) with previously accumulated codeword lengths to produce the control signal which directly shifts the decoding window by the number of bits in the just decoded word. When all the bits in the first latch have been decoded, the next bit sequence in the buffer is input to the second latch while the previous bit sequence in the second latch is transferred to the first latch. The decoding window is then adjusted to the beginning of the next undecoded sequence.
Abstract:
A system and method for a modular target. The modular target system has a target coupled to at least one target support. The target support is coupled to a base. The target support has notches on the upper distal end. The modular target system has separate components which can be assembled and disassembled without coupling devices such as bolts, screws, etc. This allows the modular target to be stored in more compact locations and configurations.

A method for cycling a sulfur composite lithium ion battery includes a step of charging and discharging the sulfur composite lithium ion battery at a first voltage range between a predetermined highest voltage and a predetermined lowest voltage. The lithium ion battery includes an electrode active material. The electrode active material includes a sulfur composite. The step of charging and discharging satisfies at least one conditions of (1) and (2): (1) the predetermined lowest voltage of the first voltage range is larger than a discharge cutoff voltage of the sulfur composite; and (2) the predetermined highest voltage of the first voltage range is smaller than a charge cutoff voltage of the sulfur composite. A method for using a sulfur composite as an electrode active material of a lithium ion battery is also disclosed.
Abstract:
In the method for making graphene, an electrolyte solution is formed by dissolving an electrolyte lithium salt in an organic solvent. Lithium ions are separated out from the electrolyte lithium salt in the electrolyte solution. Metal lithium and graphite are disposed in the electrolyte solution, and the metal lithium and the graphite are in contact with each other. In the electrolyte solution, lithium ions and organic solvent molecules jointly insert between adjacent layers of the graphite to form a graphite intercalation compound. The graphene is peeled off from the graphite intercalation compound.
Abstract:
The present disclosure relates to a method for making a conjugated polymer. In the method, polyacrylonitrile, a solvent, and a catalyst are provided. The polyacrylonitrile is dissolved in the solvent to form a polyacrylonitrile solution. The catalyst is uniformly dispersed into the polyacrylonitrile solution. The polyacrylonitrile solution with the catalyst is heated to induce a cyclizing reaction of the polyacrylonitrile, thereby forming a conjugated polymer solution with the conjugated polymer dissolved therein.
