  • Publication number: 20100245037
    Abstract: On Chip Smart Card verification of a cardholder using biometrics such as a fingerprint and consequent enablement of a card operating system, having an additional software layer boot prior to the commercial card operating system booting. This software layer, or boot loader, provides the drivers and functionality for the finger print sensor and on-card matching. If the cardholder is successfully authenticated, the unmodified commercial OS is then allowed to boot. If the cardholder does not authenticate with the boot loader then the card does not boot the card operating system and thus cannot be used for financial transactions.

  • Publication number: 20100042452
    Abstract: A method of online predicting maintenance of an apparatus is disclosed. Using an optical emission spectroscopy (OES) positioned on the apparatus and the change of emission spectrum intensity detected by the OES in the process, according to the detected results, measuring the parameter in the process, the function relation between the process parameter and spectrum intensity is acquired. A control threshold is decided by the processing requirement to the apparatus. When the parameter exceeds the control threshold, maintenance to the etching apparatus is engaged in order to avoid processing error caused by frequent shutdown or deficient maintenance which is estimated by experience, and hence decreasing the cost and increasing processing efficiency of substrates (such as silicon wafers) without changing apparatus and adding other online sensor, and improving production rate by avoiding waste substrates caused by error processing results.

  • Publication number: 20100027717
    Abstract: Two dimensional interpolation techniques are used to compensate for time-varying channel gain H in an OFDM system. The channel gain can be reasonably estimated at various times and at various frequencies due, for example, to the use of pilot tones. These channel estimates are used to estimate the channel gain at other times and/or frequencies by two-dimensional interpolation, interpolating first with respect to time (e.g., with respect to a symbol index s) and then with respect to frequency (e.g., with respect to a sub-carrier index c).

  • Publication number: 20090205168
    Abstract: A hinge assembly and a portable electronic device are provided. The portable electronic device includes a lid, a main body, and a hinge assembly. The hinge assembly pivotly connects the lid to the main body. The hinge assembly includes a pivot element, a torsion spring, and a hinge brace. The pivot element is formed on the lid and partially and rotatably received in the main body. The torsion spring is assembled between the lid and the main body. When the lid is in a closed position with respect to the main body, the torsion spring becomes constricted and accumulates potential energy. When the lid is opened from the main body, the potential energy of the torsion spring is released to drive the lid to rotate to an open position with respect to the main body. The hinge brace is attached to the main body for blocking an excessive rotation of the lid with respect to the main body.

  • Publication number: 20090158552
    Abstract: A flip-type electronic apparatus includes a base panel, a cover, and a latch mechanism pivotably fastening the cover to the base panel. At least one post extends from the cover into the base panel. The latch mechanism includes a button mounted on the base panel, and a sliding bar received in the base panel. At least one limiting portion is formed on one lateral side of the sliding bar receiving the post of the cover. The sliding bar forms a pair of inclined operating surfaces, and the button forms at least one inclined actuating surface abutting at least one of the pair of inclined operating surface. When the button is pressed, the actuating surfaces pushes the operating surfaces to cause the sliding bar to move away from the button, and thus the post is released from the limiting portion for opening the cover of the electronic apparatus.

  • Publication number: 20090041121
    Abstract: Scalable video coding based on H.264/AVC uses motion compensation, which results in motion vectors and residual pictures. To optimize the encoding of the residual pictures of the enhancement-layer, they can be predicted from the base-layer. This requires complex encoders and decoders. Simplified residual prediction techniques are provided that focus on reducing the encoding and decoding complexity of the spatial scalable enhancement-layer with optimized coding efficiency. The method for encoding video data containing high-pass frames and low-pass frames comprises the steps of encoding the low-pass frames, wherein residual prediction may be used, splitting the high-pass frames into two interleaving frame groups, encoding the frames of the first of said frame groups, wherein residual prediction may be used, and encoding the frames of the second of the frame groups using an encoding method without residual prediction.

  • Publication number: 20090029652
    Abstract: To make more efficient use of power resources, a mobile device adjusts the power necessary for receiving and/or transmitting data in response to signal quality. As the quality of received signals change, the device alters the power used to transmit and/or receive signals. When signal quality is poor, more power is used to receive the signal to maintain device functionality. When signal quality is strong, less power can be used while still maintaining device performance. This preserves device functionality while allowing the device to conserve power when possible.

  • Publication number: 20090016447
    Abstract: Packetized video data with a base-layer and at least one enhancement-layer organized in a GOP structure may contain packet loss errors. A method for detecting such errors comprises the steps of reading header information relating to a layer, generating a scheme or selecting a predefined scheme according to said header information, the scheme comprising display order number, number of reference frames and temporal level for the frames of the respective layer, extracting from received video data frames display order number, number of reference frames and temporal level parameters, and detecting that one or more frames or packets are missing, wherein the received parameters are compared with the parameters of expected frames according to said scheme and a missing packet or frame is determined by a mismatch between received and expected parameters.

  • Publication number: 20090003445
    Abstract: In video coding, prediction of P- and B-frames is based on reference frames, which are indicated by reference picture lists. Scalable video coding (SVC) requires this for both, base-layer and enhancement-layer. The invention describes a decoding process for reference picture list construction for spatial enhancement layer. With just one flag of syntax modification, it provides simpler and direct reference lists construction process. By using this, complicated RPLR and other syntaxes can be skipped, and the RPLR process for spatial enhancement layer can also be avoided. The process also can be used as for error concealment when the spatial enhancement layer slice is lost.
