System for encapsulating Ethernet frames over very high speed digital subscriber lines
An apparatus for and method of encapsulating Ethernet frame data in Very high speed Digital Subscriber Line (VDSL) frames. The VDSL frames are transmitted over a point to point VDSL link where they are subsequently extracted and forwarded as standard Ethernet frames. The VDSL facility transport system comprises an Ethernet to VDSL Consumer Premises Equipment (CPE) coupled to a DSL Access Multiplexor (DSLAM) over a VDSL transport facility. The Ethernet to VDSL CPE functions to receive a 10BaseT Ethernet signal and encapsulate the Ethernet frame into a VDSL frame for transmission over the VDSL facility. The DSLAM is adapted to receive VDSL frames, extract Ethernet frames therefrom and generate and output a standard Ethernet signal. Ethernet frames are encapsulated within VDSL frames and transmitted on the wire pair without regard to the state of the SOC signals. This overcomes the problems associated with syncing the transmission of the Ethernet data with the SOC signals. The present invention also provides a method of providing the receiving station an indication of the start of a VDSL frame. A preamble having certain desirable characteristics such as good autocorrelation properties, is used by the receiving station to identify the start of a VDSL frame. To further ensure that a detected start of frame is valid, the length field of the VDSL frame is examined for a legal length value. |

Semiconductor memory device, and method of controlling the same
An internal voltage generator when activated, generates an internal voltage to be supplied to an internal circuit. Operating the internal voltage generator consumes a predetermined amount of the power. In response to a control signal from the exterior, an entry circuit inactivates the internal voltage generator. When the internal voltage generator is inactivated, the internal voltage is not generated, thereby reducing the power consumption. By the control signal from the exterior, therefore, a chip can easily enter a low power consumption mode. The internal voltage generator is exemplified by a booster for generating the boost voltage of a word line connected with memory cells, a substrate voltage generator for generating a substrate voltage, or a precharging voltage generator for generating the precharging voltage of bit lines to be connected with the memory cells. |

Electrochromic mirror
In an electrochromic mirror, an insulating film is disposed between a conductive reflective film and an electrolytic solution and the conductive reflective film and the electrolytic solution are electrically insulated from each other except inside of insulating film side small holes. Accordingly, in a portion where the insulating film side small holes are not formed, the conductive reflective film does not come into contact with the electrolytic solution, as the result, a ferrocene ion is not reduction-reacted. Thereby, a current is very effectively suppressed from steadily flowing between the conductive film and the conductive reflective film due to repetition of a redox reaction of ferrocene, resulting in very effectively suppressing a voltage from dropping due to the current. |

Multiple clock signal generation from a common oscillator
A system and method of providing a clock signal to a navigation satellite receiver in a device is disclosed. A clock signal generated by a voltage controlled temperature compensated crystal oscillator (VCTCXO) in a cellular engine of the same device is appropriated to clock a numerically controlled oscillator (NCO) programmed to generate an adjusted clock signal suitable for use in receiving signals from navigation satellites and to heterodyne them down to baseband or an intermediate frequency for processing. Preferably, if the cellular engine has an automatic frequency control (AFC) module for adjusting the voltage control input to the VCTCXO to compensate for a change in the operating environment of the cellular engine, the AFC module modifies the control word in the NCO to counteract such adjustment so that the adjusted clock signal provided to the navigation satellite receiver is not unduly impacted.
