摘要:
The present invention provides an audio/visual data communication system including an audio/visual data reproducing device capable of changing the type of data to be transmitted. Further, the present invention provides an audio/visual data transmitting device and an audio/visual data reproducing device forming the audio/visual data communication system. An audio data reproducing speaker 3 includes an instruction input unit 33 that inputs an instruction to change data transmitted from an audio data transmitting device, a message generating unit 32 that generates a message for requesting to change data on the basis of the instruction, and a message transmitting unit 31 that transmits the message. The audio data transmitting device includes a message receiving unit that receives the message transmitted from the message transmitting unit 31, a data setting unit that sets data on the basis of the message, a data generating unit that generates transmission data on the basis of the data set by the data setting unit, and a data transmitting unit that transmits the transmission data.
摘要:
A wireless temperature sensor that is attached to the patient's skin in order to measure the patient's temperature, thereby adopting a patient moving in the facilities as a measuring object. The wireless sensor is a wireless temperature sensor□having a function of wirelessly transmitting measured data through a chip antenna, and the chip antenna has a length of a shortening coefficient so as to be received in a container, and is received in the container. In addition, the invention provides a wireless interface device in which a wireless communication function is provided to a wireless communication card having a low carrier frequency, a small antenna, an enlarged communication distance, and low power consumption. Furthermore, the invention provides a wireless sensor system in which the sensor notifies a patient of surrounding environment information by a wireless communication device whereby a base station collects the environment information from a plurality of sensors.
摘要:
A communication system and a communication method arranged to obtain a diversity effect in mobile communication, to reduce the influence of multipath interference, fading or the like, to perform comparatively simple information communication such as message communication with improved reliability, and to achieve effective utilization of frequencies. A plurality of base stations having receivers are provided around an urban area within base station zones. The base stations repeatedly transmit the same message data. Receiving repeaters are provided in the urban area and small or medium suburban zones. Each receiving repeater relays a signal from a small mobile terminal via an Internet network if the output level of the mobile terminal is so low that direct transmission to one of the base stations is impossible. A 25 kHz frequency band is divided into four narrower bands of 6.25 kHz in one of the embodiments. Of frequencies f1, f2, f3, and f4 in these bands, frequencies f1 to f3 are used for “down data transmission” from the base stations to a mobile terminal while f4 is used for “up data transmission” from the mobile station to one or more of the base stations.
摘要:
Methods and compositions are provided for expression of polypeptides in transformed bacterial hosts. A novel class of plasmid cloning vehicles includes a DNA sequence coding for the desired polypeptide linked in reading phase with one or more functional fragments derived from an outer membrane protein gene of a gramnegative bacterium. The methods utilize such plasmids to introduce genetic capability into micro-organisms for the production of proteins, such as medically or commercially useful hormones, enzymes, immunogenic proteins, or intermediates therefor.
