Patent CA-2085982-A1 (CA)
Inventor: ZIMMERMAN STEPHEN M
IPC: H01J1/30
Filed: 1990-10-17
Abstract: The present invention relates generally to new structures for a field emission cathode and processes for fabricating the same. The field emission is made of any material that is capable of emitting electrons under the influence of an electrical potential. A process for making one embodiment of the invention includes the steps of forming a hole (15) in a substrate (5), depositing a first material (20) in said hole to form a cusp (21), depositing an electron emitting material (30) to fill at least partly said cusp and removing the first material to expose a portion (31) of the electron emitting material. The field emission cathode has several unique three dimensional structures. The basic structure comprises a layer of material with cathode tips. For a more complex structure the cathode tip is preferably accurately aligned inside an extraction/control electrode structure, in preferably a vacuum environment. The structures of this invention can be fabricated to be connected to other similar field emission cathodes or to other electronic devices.

Title: Gas turbine meter
Inventor: ZENGER HELMUT
IPC: G01F1/10
Filed: 1993-02-11
Abstract: Abstract A gas turbine meter that is miniaturized based on its design is disclosed.  While the size of the gas turbine meter is small, it performs all the functions of prior gas turbine meters and has a large rangeability over a very large range of pressure.   The turbine meter includes a body which is bilateral or symmetrical, permitting the turbine meter to be installed in either orientation in a flow line.  Diffusers are included with the turbine meter that maintain the rotor of the turbine meter in position and prevent dust from entering into bearings which connect the rotor with the diffusers.  The rotor of the turbine meter optimally has twelve flat blades, each having an angle of 45° from the plane of the blank in which it was made.  Close clearance is maintained between the blades and the interior of the meter.  Notches are formed at the lower end of the blades, thereby forming the shafts of the blades which are optimally sized to increase stiffness.   The magnetic strength of the magnetic pick-up which measures the rate of rotation of the blades within the interior of the housing of the meter has a small gauss strength to avoid magnetic drag.

IPC: G06F1/025
Filed: 1993-06-25
Abstract: ABSTRACT OF THE DISCLOSURE In a hearing aid comprising an input transducer, processing circuits for useful signals including an output stage and an output transducer, the useful signals are sampled with a sampling frequency before the output stage, are converted into data words, and are also processed in discrete-time fashion. The digital data words are capable of being converted into pulse-duration-modulated signals without being re-converted into analog signals. For this purpose, the processed data words can be read into a counting circuit via at least one input which can be placed into an initial condition with counting pulses after every read-in data word. The output stage is designed as a switching amplifier and is driven with an output signal of the counting circuit.

IPC: G06F9/38
Filed: 1993-09-27
Abstract: ABSTRACT            A   method   and   system   for   increased   instruction synchronization efficiency in a superscalar processor system which  includes  instructions  having  multiple  source  and destination operands.  Simultaneous dispatching of multiple instructions creates a source-to-destination data dependency problem  in  that  the  results  of  one  instruction may be necessary to accomplish execution of a second instruction. Data dependency hazards may be eliminated by prohibiting each instruction from dispatching until all possible data dependencies  have  been  eliminated  by  the  completion  of preceding   instructions;   however,   instruction  dispatch efficiency  is  substantially  decrease  d  utilizing  this technique.  Data  dependency interlock  circuitry  may  be utilized to clear possible data dependency hazards; however, the complexity of such circuitry increases dramatically as the  number  of   interlocked   sources   and  destinations increases. The method and system of the present invention utilizes  data  dependency  interlock  circuitry  capable  of interlocking two source operands by two destination operands for  each instruction.  Instructions having three  or more source operands are interlocked at the dispatch stage for the  first  two  source  operands  utilizing  existing  data dependency interlock circuitry. Thereafter, the instruction is dispatched only after data dependency hazards are cleared for  the  first  two  source operands,  utilizing  the  data dependency  interlock  circuitry,   and  all   instructions preceding the instruction have been completed, eliminating possible  data  dependency  hazards  for  the  third  source operand.  In this manner,  instructions which include three source  operands may be  synchronized without  requiring  a substantial increase in data dependency interlock circuitry and with only a slight degradation in system efficiency.

Filed: 1992-04-06
Abstract: A vehicle operated remote control access system (C) for obtaining access to a controlled environment using the headlight system (32) of a vehicle having a high beam operation and a low beam operation. The remote control access system (C) comprises a switching sensor circuit (44, 52, 50, 48, 56) for detecting a sequence of switching from a low beam to a high beam operation or from a high beam to a low beam operation of the vehicle. Two or more of these switching sequences may be employed in the present invention. A  timing means (62) is provided with the circuit (44, 52, 50, 48, 56) in order to determine if a switching sequence from a low beam operation and then from a high beam operation back to a low beam operation, and possibly with a second sequence of back to high beam and then low beam operation, occurred within a predetermined time interval. If the one or more required switching sequence did occur in this time interval, then the remote control system (C) is energized to open a gate or a door. If the switching from the low beam to the high beam and back to the low beam did not occur within the predetermined time interval then no energization of the remote control system (C) will occur and the system resets to neutral.
