92 results about "Reproduction function" patented technology

Men's and women's reproductive systems work together to produce offspring. The reproductive system is the key to the procreation and survival of the human race. Human reproduction is the effort of a male and female that involves four functions of the reproductive systems.

Copy prevention method and apparatus of a digital recording/reproducing system employing a marker including copy protection information and code data for descrambling

<DEL-S DATE="20010213" ID="DEL-S-00001">A copy prevention method and apparatus of a digital magnetic recording / reproducing system performs the copy prevention function by encoding to insert a marker involving copy prevention function information and executing the function and allows a program supplier to realize a desired copy prevention function of various patterns, in which the marker formed by a control word for scrambling audio and video bit straps and copy prevention information for preventing an illegal copy is encrypted by an encoded key to be multiplexed with the audio and video bit strips scrambled by the control word. The marker transmitted is detected from the bit strips to be decrypted and analyzed by the encoded key to determine whether the copy is permitted or not, so that the detected marker is updated to be recorded on a video tape and the control word is produced from the marker to perform the descrambling to supply the result to a monitor to be displayed. Thus, the program supplier selects the copy prevention function, and a separate format converting apparatus is not required since a field defined within a GA format is utilized while an existing DVCR is not need to be changed for performing the copy prevention function as the data amount to be recorded is not increased.<DEL-E ID="DEL-S-00001"> <INS-S DATE="20010213" ID="INS-S-00001">The method and apparatus for transmitting and / or recording digital data generates control data and initializes a scrambler based on the control data. Digital data is scrambled using the scrambler. A marker is formed including the control data and the scrambled digital data and the marker are transmitted or recorded as a packet. The packet includes a header, which includes the marker. When the scrambled digital data and the marker, as a packet, are received, the marker is detected and the control data is obtained from the marker. A descrambler is initialized based on the control data, and the scrambled digital data is descrambled using the descrambler. <INS-E ID="INS-S-00001">

Pig feed for promoting oestrus of sows and improving birth rate of piglets

The invention belongs to the technical field of pig feed production, and in particular relates to a pig feed for promoting the oestrus of sows and improving the birth rate of piglets. The feed has the advantages that the sows are rapid in oestrus, short in period and multiple in piglets. The pig feed is composed of a conventional feed which promotes the oestrus of the sows and improves the birth rate of the piglets and Chinese herbal medicines, wherein the conventional feed consists of the raw materials of corns, bean pulp, extruded soybeans, import fish meal, corn gluten meal, peanut meal, bran, soybean oil, calcium hydrophosphate, mountain flour, boar multi-vitamins, multiple minerals, lysine, choline chloride and cysteamine; the Chinese herbal medicines consist of the raw materials of herba epimedii, actinolite, leonurus, Chinese angelica, semen cuscutae and nutgrass, and in the conventional feed, the addition amount of the Chinese herbal medicines accounts for 2.0-4.0% of the total amount of the feed. According to the feed, the medicine properties of the Chinese herbal medicines are utilized on the basis that the formula of the main ingredients is optimized, thereby improving the reproduction function of the sows, promoting the early oestrus of the sows and the birth of the multiple piglets, improving the reproduction capacity and the production property of the sows.

Intelligent power utilization system and test method based on low-voltage power line carrier

ActiveCN106056896AGuaranteed to workEarly detection and prevention of hidden faultsElectric signal transmission systemsValidation methodsLow voltage
The invention relates to an intelligent power utilization system and a test method based on a low-voltage power line carrier, which adopt a systematic verification method of multicarrier module synchronous test. In the operation process, the system allocates a logic table address of an electric energy meter according to a test scale, after the logic address of each module is completely allocated, a controller simulates a main station to issue an acquisition instruction, a test platform records data of all communication routes including a real electric meter main control module, an electric meter carrier module, a concentrator downlink communication module and a concentrator uplink module, and a test result is displayed finally by virtue of data analysis and comparison. The intelligent power utilization system can realize test on the performance of communication modules of various function units such as a system main station, an acquisition terminal and the intelligent electric meter, the fault location and the rapid reproduction function, so that a convert fault can be discovered and prevented in time, the large loss caused by the running fault of the system is avoided, and the normal work of the electric utilization information acquisition system is effectively guaranteed.
