Full Four-Channel 6.3-Gb/s 60-GHz CMOS Transceiver With Low-Power Analog and Digital Baseband Circuitry

Abstract: This paper presents a 60-GHz direct-conversion RF front-end and baseband transceiver including analog and digital circuitry for PHY functions. The 65-nm CMOS front-end consumes 319 and 223 mW in transmitting and receiving mode, respectively. It is capable of more than 7-Gb/s 16QAM wireless communication for every channel of the 60-GHz standards, which can be extended up to 10 Gb/s. The 40-nm CMOS baseband including analog, digital, and I/O consumes 196 and 427 mW for 16QAM in transmitting and receiving modes, respectively. In the analog baseband, a 5-b 2304-MS/s ADC consumes 12 mW, and a 6-b 3456-MS/s DAC consumes 11 mW. In the digital baseband integrating all PHY functions, a (1440, 1344) LDPC decoder consumes 74 mW with the low energy efficiency of 11.8 pJ/b. The entire system including both RF and BB using a 6-dBi antenna built in the organic package can transmit 3.1 Gb/s over 1.8 m in QPSK and 6.3 Gb/s over 0.05 m in 16QAM.

Monitor camera system and method of displaying picture from monitor camera thereof

Abstract: In a monitor camera system comprising a monitor camera making 360-degree panning rotation and more-than 90-degree tilting rotation and a control unit for controlling the monitor camera, for masking a privacy zone in a picture taken by the monitor camera, the control unit sets mask data through the use of a contour parameter of a configuration of a mask zone for covering the privacy zone, while the monitor camera side holds the mask data to mask a portion of the picture with the mask zone defined on the basis of the mask data. According to this monitor camera system, since only a portion of the picture is masked with the mask zone, it is possible to protect the privacy from the picture taken by the monitor camera without impairing the monitoring function. In addition, since the monitor camera side holds the mask data, quick processing becomes feasible.

Linear illumination device

Abstract: A linear illumination device of the present invention includes: a guide made of a light transmitting material extending in a first direction, having a side face and at least one end face; at least one light emitter for allowing light to enter interior of the guide from the at least one end face of the guide; and a light diffusing section formed on part of the side face of the guide, for diffusing the light incident thereon, wherein at least part of the light entering the interior of the guide goes out from part of the side face of the guide facing the light diffusing section, thereby providing substantially linear illumination light along the first direction.

Dynamic channel allocation method

Abstract: A dynamic frequency allocation method of a digital, mobile, portable telephone system wherein in communications between a plurality of base stations which are connected to a public telephone network and/or a private branch exchange and which respectively generate synchronization in an independent manner and mobile stations receiving service therefrom, each base station uses a communication signal transmission channel including a frequency and a time slot pair respectively selected from a plurality of frequencies and a plurality of time slots related thereto to implement a multichannel time division multiplex/time division duplex communication. Each of the base and mobile stations receives a communication signal of a different station communicating with synchronization independent of the pertinent station by use of a different time slot at the same frequency of the channel used by the station to receive a communication sent thereto so as to measure an interval or a distance between the time slot used by the different station and the time slot assigned thereto. Based on the measurement result, a chance of a collision between these two time slots is estimated such that depending on the estimation result, the pertinent station detects free channels not being used by any other stations to conduct a channel transition to one of the detected free channels.
