Patent EP-0371662-A2 (EP)
Inventor: FULLER RICHARD C
IPC: H04B3/46
Filed: 1989-11-16
Abstract: Currently, metallic loops are tested for shorts, opens and grounds by applying a test signal (DC or 20 Hz) directly to the metallic loop. A test signal cannot be applied to any part of the network other than the metallic loop because it will be blocked by the A-to-D converters and the hybrid of the system before it can reach the metallic loop. 
     In this invention, digital signal processing is used to test a metallic loop for shorts, opens, grounds and the presence of loading coils from a remote location. Direct metallic connection to the metallic loop is no longer necessary. 
     Briefly, a test signal, in digital form, is fed into the network at some convenient location remote from the metallic loop that is to be tested. As the signal passes through the A-to-D converter from the digital section of the network to the analog metallic loop, it is converted by the A-to-D converter into an analog signal having a specific frequency and a predetermined amplitude. Defects - opens, shorts and grounds - in the metallic loop cause reflections of the analog test signal. These reflections, as they travel back toward the digital network, are converted by the A-to-D converter into digital form. The reflected signals are then detected, processed and compared to other test signals to determine the presence of shorts, opens, grounds and loading coils in the metallic loop.

Abstract: According to the invention, in a supporting-cylinder winding machine having two driven supporting cylinders (1, 2), in which the material web (5), deflected by one supporting cylinder (1), is guided from below through the supporting-cylinder nip into the cylinder bed (3), the automatic replacement of a full winding roll (4) by a new winding tube (16) is carried out by the following steps: 
 
  - the material web (5) is stopped and is weakened in the region in front of the supporting cylinder (1), and an adhesive is applied on both sides of the weakening, 
  - the weakened point is moved into the cylinder bed (3) and is stopped there below the line of contact of the empty winding tube (16) against the supporting cylinder (1), 
  - the new web start to be provided is retained on the looped-round supporting cylinder (1), 
  - subsequently, as a result of the rotation of the full winding roll (4) by means of the supporting cylinder (2), not looped round, counter to a braking force, the web (5) is severed and the web end is glued to the full roll (4), 
  - thereafter, the full winding roll (4) is removed from the winding bed (3), and after the insertion of the new winding tube (16) this is glued to the new web start as a result of the rotation of the two supporting cylinders (1, 2).

Abstract: The invention relates to a method in which, in the presence of a homogeneous steady-state magnetic field, a multiplicity of sequences, each of which comprises at least three high-frequency pulses, acts on an area of investigation, the distance between the first two high-frequency pulses being equal to the inverse of twice the scalar coupling constant J and magnetic gradient fields becoming active between or after the pulses, which fields have such an amplitude and duration that nuclear magnetic resonance signals occurring after the third high-frequency pulse are only determined by double-quantum coherence. To suppress the fat component located in the immediate vicinity of the lactic acid component of the lower Larmor frequency, it is provided that, in order to reduce the lipid component in the area of the lactate component, the second and/or the third high-frequency pulse is frequency selective in such a manner that it is active as a 90 DEG  pulse for the component coupled to the lactate component and as 0 DEG  or 180 DEG  pulse for the component coupled to the lipid component. …<IMAGE>…

Abstract: An apparatus is provided for arranging an RF trunked communication system into a multiplicity of individual RF trunked communication subsystems. Within each subsystem, the subscriber units utilize Frequency Division Multiplexing (FDM) to communicate with the fixed equipment (inbound). Also, within certain subsystems, the fixed equipment utilizes Time Division Multiplexing (TDM) to communicate with the subscriber units (outbound). One advantage of this arrangement is that the subsystems may be further arranged to share one or more inbound FDM channels and one or more outbound TDM time slots as a duplex (inbound and outbound) control channel.

Abstract: 64 regions are set on an image sensing picture of a video camera, wherein evaluating values r ij , b ij  and y ij  are obtained by averaging color difference signals R-Y, B-Y and a luminance signal Y obtained from a video signal, respectively, over one field period for each region. When producing a gain control signal for each color difference signal, fuzzy inference is made on the basis of these evaluating values and a weighting amount for each color evaluating value for each region is determined. As a result of the weighting, the contribution degree of a color difference signal in a region not including a light source color temperature axis on a color plane is reduced to achieve good white balance adjustment.

Abstract: The method and apparatus are provided to permit the accurate sensing of the height of a solder nozzle above a circuit board during operation of the solder nozzle. A non-contact limit switch 30, which provides an indication of the presence of a planar surface at a preselected proximity, is mounted in a fixed relationship with a solder nozzle 12 which is manipulatable by means of a robotic arm 18. A reference surface 38 is provided which includes a proximity sensor, such as a through beam fibre optic switch 42. The proximity sensor is mounted a predetermined distance above the reference surface and is utilized to detect the solder nozzle as it is moved toward the reference surface. By noting the position coordinates of the robotic arm at which the proximity sensor indicates the presence of the solder nozzle at the predetermined distance above the reference surface, and the position of the robotic arm at which the non-contact limit switch closes in response to the proximity of the reference surface, it is possible to accurately calculate a calibration offset value which may be utilized in conjunction with the output of the non-contact limit switch to precisely position the solder nozzle at a desired distance above a circuit board.
