| 68 | Data transfer system for numerically controlled equipment | US822422 | 1986-01-16 | US4682167A | 1987-07-21 | Yoshiaki Ikeda; Mitsuru Kuwasawa |
| A data transfer system transfers, bit by bit, serial data sent from first equipment (10) to predetermined bits of a predetermined address in a RAM (300) of second equipment (30). Each bit of the serial data sent from the first equipment (10) is transferred to a predetermined bit of a predetermined address of the RAM (300) in the second equipment (20) upon each occurrence of a clock pulse which is delivered from the first equipment (10) in synchronism with each bit data. The data transfer system includes a counter (206) which is incremented by the clock pulses and an address generator (210) which responds to the output of the counter (206) to generate an address of the RAM (300). A bit address generator (211) responds to the output of the counter (206) to generate a bit address for specifying a bit position in one address of the RAM (300), and a timing control circuit (209) responds to the output of the counter (206) to generate timing signals for a read cycle and a write cycle succeeding it during the period of generation of one address by the address generator (210). A read modify write circuit (214) substitutes bit data from the first equipment 10 for data at that bit position of a plurality of bits in parallel data corresponding to the address from the address generator (210), read out of the RAM (300) in the read cycle specified by the timing control circuit (209), which is specified by the bit address from the bit address generator (211). The substituted parallel data is transferred to the original address in the RAM (300) during the write cycle specified by the timing control circuit (209). Thus, each bit of the serial data sent from the first equipment (10) can be transferred to a predetermined bit of a predetermined address in the RAM (300) of the second equipment (30). | ||||||
| 69 | Data transmission method | US554486 | 1983-11-22 | US4584684A | 1986-04-22 | Kunihiko Nagasawa; Isao Nishibori |
| A data transmission method in which a signal receiving side produces a response code for requesting a text in response to a start request made by a signal transmitting side, and produces an acknowledgement code or a text invalid code upon receiving the requested text, dependent upon the validity of the transmission. A standby request signal is set to the signal transmitting side in response to the start request if the receiving side is not ready. The receiving side, when ready, send a transmission request signal to the signal transmitting side for requesting transmission of text. When a first transmission request signal is received following receipt of a start request code, a timer is started at the transmitting side and the text is transmitted. The receiving side can send additional transmission requests, in which case the text is retransmitted without restarting the clock. Unless the transmission of a text has been completed successfully and an acknowledgement signal received from the receiving side before the timer runs out, the transmission of the text is suspended or invalidated. | ||||||

| 73 | Wireless communication method and wireless communications apparatus | US16673978 | 2019-11-05 | US11139906B2 | 2021-10-05 | Yuanzhou Hu; Mengying Ding; Zhongfeng Li |
| A wireless communication method includes determining a length of a ZC sequence based on a resource block quantity or a subcarrier quantity corresponding to a system bandwidth and determining a reference signal sequence included in an uplink reference signal based on the length of the ZC sequence and a resource block quantity or a subcarrier quantity corresponding to an allocated user bandwidth that is a part of the system bandwidth. When different communications devices use the same system bandwidth for communication, reference signal sequences used by the different communications devices correspond to the same ZC sequence length. The ZC sequence length is exclusively designed for a resource block quantity or a carrier quantity of the system bandwidth. Generation of the reference signal sequences is related to mapped locations of the reference signal sequences. Therefore, reference signal sequences used by different communications devices have a relatively high cross correlation. | ||||||

| In a system for visualizing a stereoscopic image by displaying separate video images for the left and right eyes, sub-picture data (GRD) is created for the left eye and displayed superimposed on left-eye video data (VDD) as a left-eye sub-picture without change. The right-eye sub-picture (106) is displayed by shifting the horizontal positions at which the sub-picture data created for the left eye is displayed by prescribed widths. For example, the sub picture may include a plurality of objects (GRD-1, GRD-2, . . . , GRD-N); shift widths (108, 110) of the horizontal positions of the left and right ends of the objects are individually set and stored in the sub-picture data for displaying the objects for the right eye. A sub-picture superimposed on a stereoscopic video image can thereby be rendered in the depth direction, and the data size of the sub-picture and the amount of computation required for its display can be reduced. | ||||||
| 77 | Network scanning method and image scanning device having network scan function using the same | US11514874 | 2006-09-05 | US07895508B2 | 2011-02-22 | Kee-Chang Lee |
| A network scanning method and device are provided that allow an image scanning device to scan documents and transmit the scan data to a server. The image scanning device checks a connection between the image scanning device and a server, generates scan data by scanning documents, stores the generated scan data in a storage unit if a connection error exists between the image scanning device and the server, and checks whether the connection error between the image scanning device and the server is corrected. The image scanning device transmits the scan data stored in the storage unit to the server when the connection error has been corrected. Transmission of scan data is delayed until the connection error to the server is corrected, thereby reducing inconvenience in having to reset network settings after waiting until the connection error to the server has been corrected. | ||||||
