Abstract: 1. A circuit arrangement for correcting pincushion distortion on the screen of a television receiver with a diode modulator (5), which is controlled via an input coupling coil (6) by a stage (8) switched by a line-frequency rectangular signal which is modulated at raster frequency, and with a diode (9) connected up to the input coupling coil (6) and serving to return stored energy into a supply voltage source of the television receiver, characterised in that an electronic switch (14) is connected in parallel with the diode (9), the rectangular signal being applied to the control electrode of switch (14), and the polarity of the contract-break is opposite to that of the diode (9), so that the switch (14) permits through the input coupling coil (6) a current which is oppositely directed to the diode current during the non-conductive phase of the connected stage (8).

Inventor: RICKERT HANS
IPC: C23F13/02
Filed: 1988-02-23
Abstract: For corrosion protection of metallic surfaces in contact with an electrolyte by an external current, using an inert electrode as the external current anode, and a potentiostat, the protective current being periodically switched off and the actual potential (Eact) being measured directly between the external current anode acting in this phase as reference electrode and the surface to be protected and being compared with the protective potential (Eset) set on the potentiostat, and the difference (Eact-Eset) being utilised directly as the control variable for the protective current, it is intended that the protective potential just prevailing at the time is measurable and hence readjustable independently of the protective current which has flowed through. This is achieved when the potential (Eact) is measured after a slight time interval after switching-off and is utilised in the control phase as the control variable for the protective current flowing during the switched-on time. <IMAGE>

The invention is used in a data processing system which processes cryptographic service requests for the performance of cryptographic functions with cryptographic keys which are associated with control vectors defining the functions which each key is allowed by its originator to perform.   The invention includes a cryptographic facility characterized by a secure boundary through  which  passes  an  I/O  path  for  receiving  a cryptographic key and its associated control vector, and for providing a response thereto,  there being included within  the  boundary  a  cryptographic  processing means coupled to the I/O path and a master key storage coupled to the processing means, for providing a secure location to execute a cryptographic function with the cryptographic key.   In accordance with the invention, a first control vector checking means has an input to receive at least a first portion of the associated control vector and to receive a cryptographic service request to perform the cryptographic function with the cryptographic key,  for performing a first check of the first portion of the associated   control   vector   to   determine   if   the cryptographic function is authorized to be performed by the cryptographic key.  The first control vector checking means has a first authorization output coupled to the cryptographic processing means,  for outputting a first authorization signal that the cryptographic function is authorized to be performed by the  cryptographic  key.          Further in accordance with the invention, a second control vector checking means has an input to receive at least a second portion of the associated control vector and to receive a cryptographic service request to perform the cryptographic function with the cryptographic key,  for performing a second check of the second portion of the associated   control   vector   to   determine   if   the cryptographic function is authorized to be performed by the cryptographic key.  The second control vector checking means has a second authorization output coupled to the cryptographic processing means, for outputting a second authorization signal that the cryptographic function is authorized to be performed by the cryptographic key.  The cryptographic processing means initiates the execution of the cryptographic function with the cryptographic key in response to receiving the first and second authorization signals.   In this manner,  distributed control vector checking  operations  are  enabled  for  multiprocessing, remote   terminal,   smart   card   and  multiprogramming applications.

Abstract: A method and apparatus for advance warning signalling to a motorist of an ice condition on a driving surface. The method steps include mounting a plurality of traffic signalling devices along a driving surface for sensing the prevailing temperatures and thereby continuously signal a motor vehicle operator of the changes in temperature as he approaches a driving surface subject to freezing to permit him to take any necessary precautionary corrective action in driving the motor vehicle.  The signalling devices utilize thermostat elements for sensing a narrow temperature range adjacent the freezing temperature and provide visible signals, preferably two colors for signalling a warm or non-hazardous temperature, a cold temperature signalling a frozen driving surface or a combination or mixture of the colored signals to permit the motor vehicle operator to be warned, in advance, as he appraoches a driving surface that is becoming colder, leading to a stretch of a driving surface that may be frozen.

Title: Cordless loud speaking telephone
Inventor: SUDO YOZO
IPC: H04M1/62
Filed: 1990-02-21
Granted: 1995-08-22
Abstract: A cordless loud-speaking telephone of the present invention is shaped to be placed on a table or desk or to be suspended from a ceiling.   Unlike cordless portable telephones of the handy transceiver type, it enables hands-free talking or communication through a receiving speaker and a transmitting microphone located outside a casing.   An antenna conductor and counterpoises are projected from the casing, and a microphone is attached to the counterpoises or the antenna conductor  such that the microphone  is separated as remotely as possible from the speaker in the casing.   As a result, howling and echo which disturb talking or communication via the telephone can be suppressed.  Further, plural microphones are attached to plural antenna conductors or counterpoises to cancel the sound of the receiving speaker to prevent the voice from again entering the microphones, or the microphones are attached to the counterpoises or the antenna conductors in such a manner that they effectively receive the voice from the mouth of a talking person from a certain direction.  This enables hands-free talking or communication to be more effectively and reliably achieved.

Filed: 1991-03-13
Granted: 1995-07-11
Abstract: A structure especially useful in a configurable logic array includes a plurality of conductive interconnect lines located along the perimeter of a logic array chip. Lines running from exterior pins or pads can be used by a programmable interconnect circuit to control signals applied to these interconnect lines.  In particular, both the signal and the complement of the signal can be used by the programmable interconnect to control application of a supply voltage to an interconnect line.  A second supply voltage is applied through a resistor to the interconnect line with the result that the interconnect line will carry a logical signal representing a logical function, for example AND, of a selected set of input signals or their complements.  Lines running from points interior to the configurable logic array chip may also contribute to the signal generated on an interconnect line.  In one embodiment, bidirectional programmable interconnect circuits allow the input pins to function as either input or output pins.  An application of the decoder circuit is described for use with a latch as a data/address demultiplexer.
