摘要： A photodetection system and related circuitry designed to sense the intrusion of an opaque object in a light plane. Upon sensing the intrusion, the system quickly initiates a machine-stopping sequence prior to the opaque object coming into contact with the machine while that machine is operating. The system comprises a SYSTEM microcontroller and a WATCHDOG microcontroller, both of which operate an output control device of the light curtain switch of the invention, wherein the output control device comprises a plurality of electromechanical relays. Both microcontrollers also perform system hardware and software integrity checks. Furthermore, the WATCHDOG microcontroller evaluates the performance of the SYSTEM microcontroller by transmitting a false intrusion signal to a photosource, determining whether the false signal has been detected, and then verifying that the SYSTEM microcontroller has initiated the machine-stopping sequence. The machine-stopping sequence may be overridden by the WATCHDOG microcontroller, or it may be initiated if the false signal is not detected. The combination of electronic, mechanical, and optical modules of the present invention provides improved reliability and accuracy. In addition, the SYSTEM microcontroller and the WATCHDOG microcontroller are designed so as to reduce the system's sensitivity to spurious signals.
摘要翻译：光检测系统和相关电路，设计用于感测光平面中不透明物体的侵入。在感测入侵时，系统在该机器正在运行之前，在不透明物体与机器接触之前，快速启动机器停止序列。该系统包括SYSTEM微控制器和WATCHDOG微控制器，两者都操作本发明的光幕开关的输出控制装置，其中输出控制装置包括多个机电继电器。两个微控制器还执行系统硬件和软件完整性检查。此外，WATCHDOG微控制器通过向光源发送假入侵信号，确定是否检测到伪信号，然后验证SYSTEM微控制器已启动停机序列来评估SYSTEM微控制器的性能。机器停止序列可能被WATCHDOG微控制器覆盖，或者如果未检测到假信号，则可能启动停机序列。本发明的电子，机械和光学模块的组合提供了改进的可靠性和精度。此外，SYSTEM微控制器和WATCHDOG微控制器被设计为降低系统对寄生信号的灵敏度。

摘要： Various methods and systems for efficiently performing the blind decoding of downlink signals is described. Several forms of arranging possible CCE combinations are examined and investigated. Based on PDCCH size estimation/information, CCE concatenations that are most likely (of limited sets) can be arrived at. Tree-based concatenations are also devised using largest CCE ordering to align smaller CCE sizes to similar boundaries. By such ordering, the search space for all possible CCE ordering and sizes can be reduced to an efficient tree. Set mapping between possible lnposelstartCCElnposelend/REs are also described using a first set to secondary and tertiary sets. Various other ordering and sorting schemes are also detailed that enable a blind decode of a PDCCH channel to be efficiently performed.

摘要： Management of uplink resources in a wireless communication is presented. In one embodiment, management of uplink resources comprises receiving a multi-bit acknowledge (multi-bit A/N) that is available for uplink transmission and receiving other information that is available for uplink transmission along with the multi-bit A/N. Next, it is determined whether a condition has been met. If the condition has been met, an uplink message is created comprising the multi-bit A/N but dropping the other information. If the condition has not been met, an uplink message is created which jointly codes the multi-bit A/N and the other information. The uplink message is then transmitted to a receiver.

摘要： Techniques for sending control information in a wireless communication system are described. In an aspect, a UE spreads control information across frequency with a DFT and across time with an orthogonal sequence to obtain output data for the control information. In one design, the UE receives codewords for N HARQ processes in N downlink subframes, determines an ACK value for each HARQ process, codes N ACK values for the N HARQ processes to obtain ACK information, generates output data for the ACK information, and sends the output data in one of M uplink subframes. In another aspect, first control information is processed based on a first coding and multiplexing scheme utilizing code division multiplexing in time and frequency domains. Second control information is processed based on a second coding and multiplexing scheme utilizing code division multiplexing in time domain and spreading in frequency domain.

摘要： Embodiments disclosed herein address the need in the art for reduced overhead control with the ability to adjust transmission rates as necessary. In one aspect, a first signal indicates an acknowledgement of a decoded subpacket and whether or not a rate control command is generated, and a second signal conditionally indicates the rate control command when one is generated. In another aspect, a grant may be generated concurrently with the acknowledgement. In yet another aspect, a mobile station monitors the first signal, conditionally monitors the second signal as indicated by the first signal, and may monitor a third signal comprising a grant. In yet another aspect, one or more base stations transmit one or more of the various signals. Various other aspects are also presented. These aspects have the benefit of providing the flexibility of grant-based control while utilizing lower overhead when rate control commands are used, thus increasing system utilization, increasing capacity and throughput.
