Title: A method and an arrangement for minimising the magnetizing current passing through a transformer
Inventor: GUSTAFSSON ALF
IPC: H01F27/42
Filed: 1986-05-09
Granted: 1989-07-06
Abstract: The invention relates to a method and to an arrangement for controlling the respective conduction times of two directionally opposed electrical devices (9, 10) which are mutually connected in parallel and permit current to pass therethrough solely in one direction, and which also permit current (l<sub>2</sub>) to pass through the primary winding (2) of a transformer during a respective half-period of an A.C. voltage (U,) applied to the primary winding, this control being effected so that the magnetizing current through the transformer can be advantageously minimized and/or held beneath a given limit value when an asymmetric load (4, 5) is applied to the secondary side (3) of the transformer. A magnetizing current in the primary winding corresponding to the load (5) of the secondary winding (3) is controlled through the agency of different conduction times of the two directionally opposed devices (9, 10).

Title: Method and apparatus for using full spectrum transmitted power in a spread spectrum communication system for tracking individual recipient phase time and energy
Inventor: ZEHAVI EPHRAIM
IPC: H04B7/216
Filed: 1996-01-03
Granted: 1999-07-08
Abstract: Method and apparatus for tracking the frequency and phase of signals in spread spectrum communication systems that makes more efficient use of available carrier frequency and phase information by utilizing a substantial portion or all of the energy occupying the frequency spectrum of a received carrier signal, including energy from communication signals intended for other system users. Multiple spread spectrum communication signals are input in parallel to data receivers where they are despread using preselected despreading codes at an adjustable phase angle and decoded over multiple orthogonal codes active within the communication system. Multiple decoded signals are then combined to form a single phase detection signal which is used by at least one tracking loop to track frequency and phase of the carrier signal for the received communication signals. The tracking loop generates a timing signal which is used to adjust the phase angle used during despreading. In further embodiments, the communication signals are despread using appropriate PN codes and separated into in-phase (I) and quadrature channels (Q) where data symbols are processed by fast Hadamard transformers to generate corresponding data bits. The data is formed into pairwise products between the channels and summed over multiple or all active subscriber orthogonal codes. This sum indicates a degree to which the estimated phase differs from the actual phase of received communication signals and is used to adjust the phase of application for the PN codes.

Title: Push button preset tuning cct for superheat receiver - blocks IF amplifying stages and has automatic sharp tuning
IPC: H03G3/34
Filed: 1969-07-03
Abstract: The push button preset tuning for a superheterodyne receiver uses, for example, capacity diodes for motionless tuning to the preselected broadcasting stations. The tuning selection operates by blocking one or more intermediate frequency amplifying stages which are installed in front of the regulating voltage generator for the automatic sharp tuning for the selected station. The contact for the preset tuning can be so made that it is closed during the actual movement of the selector button and operated again when the button is fully pressed in. Another possibility, enabling a simple construction to be made, is to allow the movement of the button to cause a capacitor to charge whose load voltage suppresses the I.F. stages. Discharge occurs via a resistor to release the receiver when the tuning process is finished.
