Title: Call signal discriminating system
Inventor: TAKAGI TSUTOMU
IPC: H04L27/26
Filed: 1983-12-30
Abstract: PURPOSE:To decide whether or not a signal is a call signal to the own device by binary-coding a signal on a transmission line so as to compress the amount of information, sampling the binary-coded signal repetitively at a specific period and obtaining the accumulated value of the same phase of the sampling value of each sampling point. CONSTITUTION:When a power of a transmitter is applied, a microprocessor 102 goes to the standby mode after initial setting and awaits pulse input. Equation I is set as the sampling period in the initial setting, where T is a period of a call signal specific to a transmitter, N is a sampling point number per T, and the N is 8 and the I is selected from integral numbers such as 3, 5, 7. When the signal is the call signal of the own device, the pattern of the accumulated value of the sampling value of each sampling point is as shown in Fig. (a) ideally and if a slight frequency shift or noise exists, the pattern is as shown in Fig. (b). When the signal is the call signal of the own device in this way, the accumulated value is increased monotonously from a certain sampling point and when the value reaches a maximum value, the value is decreased monotonously. Whether or not the signal is the call signal to the own device is discriminated by recognizing the accumulated pattern with a simple method comparing sequentially the accumulated value of the adjacent sampling point.

Title: Arrangement of annotation to display device
Inventor: MAAKU DEII PURITSUTO
IPC: G06F3/048
Filed: 1994-10-13
Abstract: PURPOSE: To arrange notes in various sizes without being overlapped on a display device. CONSTITUTION: Each note is displayed with the boundary box of the quadrangle by an identification line or arrow for connecting the quadrangle with the display objects of the note display objects, and this quadrangle and the line are stored in a list. At the time of arranging additional nodes on a display device, the notes are tried at various positions, and whether or not they are overlapped with the notes which are already displayed on the display device is judged. The trial positions are selected by changing the length of the identification line and an angle formed by the identification line and a horizontal line. When the desired positions are found, the notes are arranged on the display device, and added to the list of the arranged notes. The overlapping test is constituted of simple geometrical operations so that it can be operated at a high speed. Also, a high speed retrieval is operated at first, and when the proper positions are not found, a further perfect retrieval can be operated the next so that the high speed operation can be attained. Moreover, the arrangement of the notes can be changed so that the notes can be arranged without being extremely tightly packed.

Filed: 1991-09-26
Abstract: PURPOSE:To enhance the DTMF detection accuracy by utilizing an LSP parameter as it is at message recording so as to discriminate a DTMF signal and discriminates it together with a detection output of a DTMF detection section. CONSTITUTION:A hook-off signal comes to a line interface section 1, a voice guidance informing a voice storage device is outputted. When a subscriber enters a box number, the box number is converted into a numeral string by a conventional DTMF code detection section 4 and the result is sent to a central control section 7, which inputs a voice message outputted from the line interface section to a voice coding section 2 and its output is inputted to a DTMF signal discrimination section 8 and stored in an area corresponding to the box number of a voice storage section 6. In this case, the DTMF signal discrimination section 8 discriminates a DTMF signal based on an output of the conventional DTMF code detection section 4 and spectrum power information by an LSP parameter obtained by the voice coding section 2.
