Title: Narrowband applications using ATM switching and transport
IPC: H04Q11/04
Filed: 2000-07-12
Abstract: ATM is used as a transport and switching mechanism in a hybrid STM/ATM network while the signaling remains normal narrowband signaling. The narrowband signaling is transported on permanent paths over ATM connections, and the narrowband speech channels are transported on ATM and switched on a "Per call basis" (on-demand) through an ATM switch. A translator formats a call-setup-related signaling message into ATM cells so that the signaling message can be routed through an ATM switch to a circuit switched (STM) node. The circuit switched node (PSTN/ISDN) sets up a physical connection for the call and generates a further signaling message therefor that relates to the physical connection. The ATM switch routes an ATM cell-formatted version of the further signaling message to another ATM switch over an ATM physical interface. Thus, the ATM switch switches both narrowband traffic and signaling for the call over the ATM physical interface.

Abstract: 본 발명은 저역의 인접한 NTSC 신호에 의해 야기된 간섭에 민감한 디지털 신호를 수신할 때 인접한 채널 간섭을 감소시키는 디지털 및 아날로그 신호를 수신하는 텔레비젼 수상기에 관한 것이다. 그 디지털 신호를 수신할 때, 수상기는 중간 주파수(IF) 신호를 생성하도록 그 디지털 신호를 국부 발진기(LO) 신호로 헤테로다인 처리한다. 마이크로프로세서는 디지털 방송 채널에 관한 저장된 정보를 찾기위해 메모리 유닛을 서치하고 저역의 인접한 NTSC 채널의 존재 유무를 결정한다. 저역의 인접한 NTSC 채널이 존재하는 경우에, 마이크로프로세서는 IF 신호를 디지털 신호 처리기내에 있는 탄성 표면파(SAW) 필터의 하부 대역 에지쪽으로 편이하게 하는 LO 신호의 주파수를 편이해서, 저역의 인접한 NTSC 채널을 더 감쇄시킨다.

Title: A memory expansion module with stacked memory packages
IPC: G11C8/12
Filed: 2000-11-15
Abstract: A memory expansion module with stacked memory packages. A memory module is implemented using stacked memory packages. Each of the stacked memory packages contains multiple memory chips, typically DRAMs (dynamic random access memory). The memory may be organized into multiple banks, wherein a given memory chip within a stacked memory package is part of one bank, while another memory chip in the same package is part of another bank. The memory module also includes a clock driver chip and a storage unit. The storage unit is configured to store module identification information, such as a serial number. The storage unit is also configured to store information correlating electrical contact pads on the module with individual signal pins on the stacked memory packages. This may allow an error to be quickly traced to a specific pin on a stacked memory package when an error is detected on the memory bus by an error correction subsystem.
