    Abstract: An ADC and method comprises a hybrid-type sigma-delta modulator comprising a digital delta-stage and an analog sigma-stage, wherein the analog sigma-stage comprises an analog low-pass filter adapted to only pass a low frequency audio band between 0-20 khz of a PWM wave, and wherein the digital delta-stage comprises a PWM wave generator; a pair of MOSFETs; and a power supply unit outputting voltage to the pair of MOSFETs. The ADC comprises a comparator attached to the hybrid-type sigma-delta modulator; a low-pass filter configured in a digital domain and for receiving a signal output of the comparator and remove high-frequency components of the comparator output above the audio band; a PWM back converter adapted to receive the filtered signal output and translate the digital low-pass filtered signal output to a power supply transient value in a digital format; and a dither signal source for injecting a dither signal to the digital delta-stage.

    CPC classification number: G06F21/14

    Abstract: A system for preventing accurate disassembly of computer code. Such code masking, referred to as “obfuscation,” is useful to prevent unwanted parties from making copies of an original author's software, obtaining valuable information from the software for purposes of breaking into a program, stealing secrets, making derivative works, etc. The present invention uses assembly-language instructions so as to confuse the disassembler to produce results that are not an accurate representation of the original assembly code. In one embodiment, a method is provided where an interrupt, or software exception instruction, is used to mask several subsequent instructions. The instruction used can be any instruction that causes the disassembler to assume that one or more subsequent words, or bytes, are associated with the instruction. The method, instead, jumps directly to the bytes assumed associated with the instruction and executes those bytes for a different purpose. A preferred embodiment works with a popular Microsoft “ASM” assembler language and “DASM” disassembler. The instructions used to achieve the obfuscation include “INT” instructions. Using this approach up to 17 bytes of obfuscation can be achieved with five instructions. Each instruction remains obfuscated until executed and returns to an obfuscated state afterwards.

    Abstract translation: 一种防止计算机代码准确拆卸的系统。 被称为“混淆”的代码掩码有助于防止不必要的各方复制原始作者的软件，从软件获取有价值的信息，以打破程序，窃取秘密，制作衍生作品等。 本发明使用汇编语言指令，以便将反汇编器混淆以产生不是原始汇编代码的精确表示的结果。 在一个实施例中，提供了一种方法，其中中断或软件异常指令用于屏蔽几个后续指令。 所使用的指令可以是导致反汇编器假设一个或多个后续字或字节与指令相关联的任何指令。 相反，该方法直接跳转到与指令相关联的字节，并为不同目的执行这些字节。 优选实施例与流行的Microsoft“ASM”汇编语言和“DASM”反汇编器一起工作。 用于实现混淆的指令包括“INT”指令。 使用这种方法可以使用五个指令来实现高达17个字节的混淆。 每个指令仍然被混淆，直到执行，然后返回到模糊状态。

    Abstract: This invention discloses a method for controlling inter-frequency hard handoffs by using user equipment(UE) event-triggered reporting mode in a WCDMA system, being applicable to geographical cells covered by multiple frequency points. Its main technical feature is that the radio network controller (RNC), after receiving reported results from the UE, performs the decision and execution according to the specific events. This method has the advantages of a reasonable logic and high efficiency, being able to well ensure the realization of the inter-frequency handoffs required by a WCDMA system, improved communication quality, reduced transmission power of the UE, reduced interference to other cells, and increased system capacity, etc.
