Abstract: To detect an impact due to a shock with high precision and stability, a shock sensor provides a sufficiently long closure interval of a contact of a reed switch (1) enough to carry out signal processing. A gap between an outer surface of a magnet (2) and an inner wall (8) of a housing (7) defining a passage for the magnet (2) comprises a first gap (G1) between a stationary position and an activating position and a second gap (G2) between the activating position and a stop position. The inner wall (8) is formed so that the first gap (G1) is greater than the second gap (G2). The velocity of the magnet (2) is smaller in travelling in the second gap (G2) than in the first gap (G1) because air resistance is greater in the second gap (G2). Accordingly, the closure interval is increased. Alternatively, the closure interval of the contact of the reed switch (1) is adjusted by first and second coil springs (3, 49) which independently urge first and second magnets (2, 48) in an anti-impact direction, respectively. To cope with various collision modes, spring constants (k1, k2) of the first and the second coil springs (3, 49) and masses (m1, m2) of the first and the second magnets (2, 48) are selected while the velocity of shock-responsive movement is differed between a first group comprising the first magnet (2) and the first coil spring (3) and a second group comprising the second magnet (48) and the second coil spring (49).

Abstract: A device for connecting the connection pins of an integrated circuit mounted in a dual-in-line (DIL) package (2) to printed circuitry on a printed circuit board (1) in n different ways, with n being an integer ≧ 2. The printed circuit board (1) comprises contact holes which are electrically connected to the printed circuitry and are each suitable for receiving a connection pin of the DIL package (2). To avoid the use of so-called jumper blocks for the different ways of connection, the contact holes form a matrix of p columns and q rows, with p being at least equal to the number of connection pins on a long side of the DIL package (2), q being at least equal to 2n, and the distance between successive rows of contact holes being such that n-1 rows of free contact holes are located between the rows of connection pins on the opposite long sides of the DIL package (2) when these rows of connection pins have been mounted in two rows of contact holes. The contact holes are preferably located in an IC base (6), so that the desired connection can be chosen by placing the package (2) in this base in one of the n possible ways. In this way the package (2) is connected to one of the different outputs (3,4,5).

Abstract: A method of analysing the distortion produced by a linear power amplifier (20) is described. In this method two tones are applied to the amplifier and the resulting down-mixed signal is subjected to an FFT in order to derive the spectrum and plot the amplitude and phase distortion against the two tone amplitude. Analysis of the results of such testing allows the pre-distortion circuits (8,10,12) to be designed to compensate for distortion produced by the amplifier over the complete operating frequency range of the transmitter.

IPC: H03K5/02
Filed: 1992-08-19
Abstract: A fail safe level shifter (30) assures that, when an input signal voltage level falls below a given threshold voltage, the output is either a constant high or no signal at all. Additionally, a range of digital high signals having a voltage less than the given threshold voltage may be shifted by the fail safe level shifter. The fail safe level shifter expands the width of an N-MOS channel of a conventional level shifter by placing two MOS switches (16, 17) in parallel. The resultant resistance allows the fail safe level shifter to register those high signals which are below the given threshold voltage. One-half of the level shifter has a N-MOS channel about one-half the width of a N-MOS channel in the other half of the level shifter. Therefore, the narrower half is unable to fully activate given the low input signals received. The fail safe level shifter thus assures that the output will be a constant high.

IPC: B26D5/30

Abstract: A pair of pull rolls unwind web material from a roll and advance the web at a preselected linear feed rate to a web cutting mechanism. The pull rolls are rotated at a preselected speed to generate the desired linear speed rate for cutting the web at selected intervals to produce blanks of a preselected length. The feed rolls are driven by a servo-motor which is operated by a controller that is microprocessor controlled. The controller is electrically connected to an encoder that is drivingly connected to a rotating knife cylinder of the web cutting mechanism. A selected length of blank to be cut from the web is inputted by the operator through a keypad to transmit a corresponding signal to the controller. In addition, the controller receives a signal from the servo-motor that drive the pull rolls, which signal is representative of the rate of rotation of the pull rolls. The inputs to the controller are compared to determine if the pull rolls are being rotated at the required speed to provide the linear feed rate that supplies the web to the cutter mechanism for producing blanks of a desired length. Should a deviation occur in the length of blank cut from the web, the controller detects the deviation and generates an output signal to the servo-motor to adjust the rate of rotation of the pull rolls. In addition, in the event a change in the length of blank cut from the web is desired, the operator changes the blank length and the controller responds by generating an output signal which adjusts the rate of rotation of the pull rolls in relationship to the position of the cutter mechanism.
