Inventor: SCHILD SIEGFRIED
IPC: D01H1/243
Filed: 1928-01-25
Granted: 1928-12-15
Abstract: 285,870. Schild, S. Feb. 24, 1927, [Convention date]. Cut-out arrangements.-Electrical systems, for example, the incoming lines L1, L2, the power transformers A, B, C and the outgoing lines L3, L4 are protected against fault by means of a maximum and minimum relay N which through switching mechanism K isolates all parts of the system on fault, and then reconnects them in sequence, and switches off the defective parts by means of a maximum current relay M. Upon removal of the fault, the defective parts are switched in again automatically. The switches which isolate the various parts of the system A, B, C, and A2, B2, C2, for example, are of the double coil type one coil when energized serving to close the switch and the other to open it. The energization of these coils from the battery D is under hand control by the selector W which determines which of the main switches shall come under the automatic control of the cutting-out and resetting controller K which is driven by the motor G when the voltage relay in one of the incoming lines assumes one of its closed positions due to increase or decrease of voltage. When, for example, the line L1 becomes live the contacts a, b of the relay N close and the motor G commences to rotate the drum. The connections of the drum controller to the main switches are such that the main switches in the system are closed in sequence. During this switching-in action, if a fault occurs in the next succeeding section (for example, between the switches A1 and A2) then the maximum relay M will operate and the main switch just closed will be opened again. In position 11 of the controller, it is stopped as the supply is automatically cut off from the motor G. If the voltage on the conductor L1 fails, for any reason, the motor is restarted and all the switches are switched off at position 13 of the drum. In position 14 the motor is again stopped and only on reappearance of voltage on line L1 is the switch mechanism again set in operation by the voltage relay N.

Title: Cartesian or polar loop or envelope elimination/restoration amplifier linearization with correction of timing errors between phase and amplitude components
Inventor: PERSSON JONAS
IPC: H03F3/189
Filed: 2000-10-17
Abstract: The invention relates to a method of adjusting a radio frequency signal produced by radio frequency circuitry in response to receipt of phase and amplitude control signals from digital baseband circuitry which operates to convert digital data signals into such phase and amplitude control signals. The phase and amplitude control signals are adjusted in the digital baseband circuitry in order to compensate for time alignment errors which occur in the radio frequency circuitry. This may be used in polar loop or envelope elimination/restoration arrangements for the linearization of power amplifiers. The same idea may be used to correct errors between the I and Q components in Cartesian feedback amplifiers.

Title: Adaptive maximum likelihood detection
Inventor: JAQUETTE GLEN ALAN
IPC: G11B20/14
Filed: 2000-11-09
Abstract: An adapter and a method for adapting a programmable digital maximum likelihood detector to a variable channel output and a calibration system for calibrating a programmable digital maximum likelihood detector from unknown data in a known code at a variable channel output, the maximum likelihood detector having a number of maximum likelihood states. A detector detects a digital sample of the recorded analog signals as corresponding to one of the maximum likelihood states. An accumulator partially accumulates the detected digital sample with prior detected digital samples corresponding to the one of the maximum likelihood states. Logic coupled to the accumulator employs the accumulated digital samples for the corresponding maximum likelihood state to determine at least one numerical metric coefficient matching the digital samples to the one of the maximum likelihood states, and updates or sets the numerical metric coefficient. Wherein the numerical metric coefficents are applied to the digital samples to generate the metrics used in determining which of the maximum likelihood states the sample corresponding to.

Title: Reduced head population detection in a disc drive
Inventor: WALKER TIMOTHY T
IPC: G11B21/02
Filed: 1999-07-01
Abstract: An apparatus and method for determining the configuration of a disc drive (100) head-disc assembly (HDA) (101). The HDA includes an array of rotatable discs (106) and an actuator assembly (110) adjacent the discs, with the actuator assembly supporting a maximum number of heads (120) in a fully populated configuration and a reduced number of heads in a depopulated configuration. Each head is disposed at a unique head position. During each spin-up of the disc drive, a servo circuit (148) determines an impedance of a selected head position having a head when the disc dive is fully populated, but not when the disc drive is depopulated. The servo circuit identifies the configuration of the HDA in relation to the determined impedance, and initializes the drive accordingly.

Title: Nozzle for soldering apparatus
Inventor: TOMBS MICHAEL
IPC: B23K3/06
Filed: 2001-01-10
Abstract: In a dip soldering process, solder 4 is pumped through a nozzle outlet 14. Leads 26 of a component 22 on a circuit board 16 are dipped into the surface 15 of the flowing solder to solder the leads 26 to a track on the underside 28 of the circuit board 16. To prevent solder bridging between the leads 26, a surface such as plate 30 is provided below the solder surface 15, and passes between the leads 26. When withdrawing the leads 26 from the solder, the solder surface 15 is dropped to the level of the plate 30, which is made of a material which is wetted by the solder, so that excess solder is drawn away from the leads, preventing solder bridging between the leads 26. Member 30 may be movable to rise through the solder surface 15 as the circuit board 16 is raised away from the surface, instead of dropping the level of the solder surface 15. Plate 30 can be replaced by a pin (44, figure 6) or the nozzle outlet 13 itself.

Title: Rotation Angle Detector
Inventor: TATEISHI ICHIRO
IPC: G01D5/16
Filed: 2002-01-23
Abstract: In a rotation-angle detector, a first detector 18 detects a movement of a driven body 13 following a rotation of a change gear 12 engaged with a rotary gear 101 of a rotary body 1, and outputs the detection result as a detection signal which gradually increases or decreases. At the same time, a second detector 19 detects a rotation of a detecting gear 15 engaged with the change gear 12, and outputs the detection result as a detection signal which repeats continuously. A detecting circuit detects a rotation angle of a rotary body based on these two detection signals. This structure allows the rotation-angle detector to produce a smaller detection error, and be downsized. Further, a simple calculation in the detecting circuit is achievable.

Title: Equalizer which opens the eye of received signal by adjusting tap coefficients to move unreliable outputs towards reliability thresholds
Inventor: WEINER NICHOLAS
IPC: H04L7/02
Filed: 2003-01-28
Abstract: A method of equalizer adaptation involves comparing equalizer output values with a centre threshold, and with at least one of a pair of outer thresholds, and adapting the equalizer in order to increase the degree of eye opening. The centre threshold represents the zero/one crossover boundary, while the outer thresholds represent a desired level of confidence in the equaliser output. The values of the outer thresholds are adapted such that a fixed proportion of equalizer output values lie between the outer thresholds, and the equalizer coefficients are adapted such the separation of the outer thresholds is increased. The equalizer coefficients are adapted on the basis of equalizer output values which lie between the pair of outer thresholds. Thus the coefficients are updated based upon the unreliable outputs and adjusted so that the output values move away from the centre threshold and thereby become more reliable.
