  • Patent number: 6227049
    Abstract: A single crystal silicon substrate (1) is bonded through an SiO2 film (9) to a single crystal silicon substrate (8), and the single crystal silicon substrate (1) is made into a thin film. A cantilever (13) is formed on the single crystal silicon substrate (1), and the thickness of the cantilever (13) in a direction parallel to the surface of the single crystal silicon substrate (1) is made smaller than the thickness of the cantilever in the direction of the depth of the single crystal silicon substrate (1), and movable in a direction parallel to the substrate surface. In addition, the surface of the cantilever (13) and the part of the single crystal silicon substrate (1), opposing the cantilever (13), are, respectively, coated with an SiO2 film (5), so that an electrode short circuit is prevented in a capacity-type sensor. In addition, a signal-processing circuit (10) is formed on the single crystal silicon substrate (1), so that signal processing is performed as the cantilever (13) moves.

  • Patent number: 6230120
    Abstract: In some call-switching systems, transmitted speech samples may be sent back (back-looping) to the sender from a telephone switching center if the switching center is unable to send the speech samples forward. When supplementary information is sent with the speech sample, back-looping may cause a problem if the sending device interprets the signal as originating from another device. To avoid this problem, transmitted samples are subjected to a check value calucation such as a checksum or a cyclic redundancy check. The check value is stored in memory and any received samples are subjected to a check value calculation and compared to the stored samples. If the comparison yields a match, then the device will know that the received samples originated from itself and can be properly handled.

  • Patent number: 6227050
    Abstract: A semiconductor mechanical sensor having a new structure in which a S/N ratio is improved. In the central portion of a silicon substrate 1, a recess portion 2 is formed which includes a beam structure. A weight is formed at the tip of the beam, and in the bottom surface of the weight in the bottom surface of the recess portion 2 facing the same, an electrode 5 is formed. An alternating current electric power is applied between the weight portion 4 and the electrode 5 so that static electricity is created and the weight is excited by the static electricity. In an axial direction which is perpendicular to the direction of the excitation of the weight, an electrode 6 is disposed to face one surface of the weight and a wall surface of the substrate which faces the same. A change in a capacitance between the facing electrodes is electrically detected, and therefore, a change in a physical force acting in the same direction is detected.

  • Patent number: 6229512
    Abstract: There is provided a display method of a flat display unit arranged so as to prevent an abnormality of a screen which is otherwise caused by coupling by inhibiting homo-polar video signals from being sampled within a sample and hold circuit having two circuits. Positive and negative polar video signals are sampled always alternately in A and B circuits of the respective sample and hold circuits of a signal line driving section by keeping the polarity of a video signal voltage before non-displaying timing same with that of the non-displaying timing, by stopping to switch the two systems of the sample and hold circuits and to output a signal when the non-displaying timing.

  • Patent number: 6222877
    Abstract: A method for performance monitoring of data transparent communication links, including a method wherein each symbol in an incoming data symbol stream is sampled at the center of each bit period to create a main line data bit stream, and concurrently sampled at a time instant displaced from the center of each bit period to create a second line data bit stream. During each bit period, the digital value of the second line data stream is compared with the digital value for the corresponding bit period in the main line. If the main line and second line digital values are the same, no error is indicated. If they are different, i.e. if, for example, the main line is bit “1” and the second line is bit zero, an error called a pseudo error is entered on a counter. The number of errors counted per number of bits or time is indicated as a pseudo error rate for each point of time displacement in the user-defined set.

  • Patent number: 6219544
    Abstract: A method of measuring radio path quality values (SQ) in a digital mobile telephone network (PLMN) comprising at least one mobile station (MS). In the method, co-ordinates (XY) of a measuring point are determined and transmitted to the mobile telephone network (PLMN). A mobile test device (TS) measures the radio path quality values (SQ) from a downlink transmission path. The mobile telephone network (PLMN) measures the radio path quality values (SQ) from an uplink transmission path. According to the invention, the mobile test device (TS) sends the results from said measurements to the mobile telephone network (PLMN) essentially without delay. The mobile telephone network (PLMN) receives the measurement results (SQ) sent by the mobile test device (TS) and combines them with its own measurement results (SQ) and with the co-ordinates (XY) of the measuring point essentially without delay.
