Filed: 1988-12-01
Granted: 1991-08-09
Abstract: The speed gun  checks  the  speed  of  moving  targets  using microwave of X-band or K-band and the radar dtector  receives  the microwave shot from the speed gun  to  give  its  intensity.  This radar detector scheme demadulates microwave received and shows its bandwidth and electric field intensity only when the microwave  is shot from the gun, while avoiding any other source  of  microwave. The ksystem  comprises  the  first  and  second  medium  frequnecy amplifying states, frequency modulator signal  demodulator  (110), microwave detecting  stage  (106,112),  electric  field  intensity detectors (111)(113)(114),  and  display  modules  (115)(116)  and warning speaker (117).

Granted: 1992-04-10
Abstract: The testing method comprises the steps of analysing  commands provided by the  operater,  and  delivering  the  results  to  the operation management and maintenance processor (OMP). The commands are delivered to the access switching processor (ASP). The  access switching maintenance process (ASMP) is asked to interconnect  the test equipment if the execution of the  test  is  verified  to  be possible after checking the status of the processors and the  test equipment. The analog subscriber interface hardware  unit  (ASIHU) is asked to connect the subscriber's equipment if the line is  not on service after checking the subscriber's line. The  subscriber's line is recovered to the service status after receiving the result of the test. The method minimises service interruption  caused  by test.

Granted: 1999-08-16
Abstract: Displacement measuring apparatus for measuring the displacement and movement of an object includes an array of sensors having an operative surface and circuitry for producing an electrical output signal whose value is dependent upon the disposition of an electrical/magnetic field producing member along the sensor array. The field producing member is disposed to contact and slide over the operative surface as the object whose displacement is to be measured is moved. The value of the electrical output signal produced by the circuitry is thus dependent upon the position of the field producing member along the sensor array and thus by the position and movement of the object. <IMAGE>

Abstract: The circuit differently handles the error of the decoder according to the selected filter in order to eliminate the output signal saturation caused by the errors. The circuit comprises: data from CD-ROM; an error processing unit (10) handling the error position interpolation according to the selected filter number; an adding unit (20A) outputting the revision data plus the output data of the error processing unit (10); a saturation protection unit (30); a filter (50A) carrying out filtering for the output of the saturation protection unit (30); and an adder (20B) providing the input signal of the adder (20A).
