Title: Method and apparatus for externally defining the operational mode of a digital radio transceiver
Inventor: SZCZUTKOWSKI CRAIG F
IPC: G06F21/86
Filed: 1990-05-03
Abstract: ABSTRACT       Different digital radio transceiver front panel escutcheon plate assemblies are provided for different optional transceiver configurations. A digital signal controller which is part of the main transceiver circuitry is capable of performing any of various basic and option functions under control of program control instructions stored in an associated non-volatile memory. Subsets of those features are selectively disabled by irreversibly modifying the transceiver unit from the outside of the unit (e.g., by cutting certain PC board pathways through holes provided in the transceiver unit front panel). The controller enables (executes) portions of the program control instructions stored in its associated non-volatile memory and disables (does not execute) other portions of the stored program control instructions in response to detection of continuity/discontinuity over those certain pathways.

IPC: G01C21/18
Filed: 1990-08-02
Abstract: A stabilized platform for mounting a camera or other sensor is suspended from a support post by a universal or Cardan joint with two torque motors powering its axes.  Below this universal joint is a rotational joint also powered by a torque motor.  A gyro stabilizer assembly comprising three orthogonally arranged gyroscopes is mounted on the platform.  Position sensors detect the precession angles of the three gyroscopes and provide inputs to servo control loops which deliver drive signals to the torque motors.  The platform including the gyro stabilizer assembly and the payload of camera or other sensor is configured such that the center of gravity is precisely located at the intersection of the three motor driven axes so to as eliminate unwanted torquing moments as a result of vehicle accelerations.

Abstract: ATRAUMATIC SCREW-IN LEAD                          ABSTRACT     An electrical stimulation lead incorporating an electrode assembly which dispenses a drug adjacent the stimulation site.  The lead is provided with a fixation helix located at the distal end of the lead.  An electrode may be extended distally within the helix.  When extended, the electrode serves as a guard against perforation or other damage to tissue by the helix.  In its retracted position, the electrode is located roughly adjacent the distal end of the lead body, and lies against the tissue to be stimulated.  Advancing and retraction of the electrode is accomplished by means of a stylet which is removably engageable with the proximal end of the electrode.  In one embodiment, the stylet functions to both advance and retract the electrode.  In an alternative embodiment, the stylet is used only to advance the electrode, and retraction of the electrode is accomplished by a resilient conductor.

Title: Emergency signal warning system
Inventor: BERNSTEIN BERNARD
IPC: G08B1/08
Filed: 1990-09-10
Abstract: ABSTRACT         This invention is an emergency signal warning system to detect the sirens of emergency vehicles and to provide a warning signal.   The system of the invention detects the sound signals varying  in  frequency  in  a  predetermined  manner  over  a predetermined frequency range.   The system includes a source of input signals which are converted from analog to digital.   A digital signal processor processes and stores the output of the converter  into groups  of predetermined numbers  of bits.   An output representative of a characteristic of the signal at the source  of  the  input  signal  corresponding  to  a  predetermined number of said groups is produced.  An alarm is produced when a predetermined pattern of variations of successive outputs occur in a predetermined time interval.

Title: Method and apparatus for non-linear dithering of digital images
Inventor: WELLS STUART C
IPC: G06T5/00
Filed: 1990-09-28
Abstract: The method and apparatus of the present invention takes into consideration that the eye is more sensitive to intensity variations at low levels of intensity than at high levels of intensity and produces higher quality dithered images by employing a sectioned or piecewise linear quantization strategy which sacrifices the fineness of interval spacing at the high end of the intensity scale in order to achieve greater accuracy of reproduction at the low end. The input intensity values are divided into a plurality of sub-ranges indicative of low intensities and high intensities. The number of input intensity levels allocated to the low intensity sub-ranges is small and the number of quantized or output intensity levels allocated to the low intensity sub-ranges is large compared to those allocated to the high intensity sub-ranges such that the interval spacing at the low intensity sub-ranges is small to provide greater accuracy at the low intensity levels where the eye is most sensitive.

Title: Drill head with integral impact hammers
Inventor: MASSE ROGER F
IPC: E21B1/00
Filed: 1991-02-22
Abstract: A drill head is disclosed, for use to drill a hole in a front of hard material such as rock, which comprises a main body acting at a central support, an upwardly projecting spindle secured on top of the main body, the spindle having a vertical axis, a fixation head on top of the spindle for detachably connecting it to a drill shaft operable in use to rotate the drill head about the vertical axis of the spindle and to pull it up toward the front hard material to be drilled, and at least two impact hammers mounted onto the main body in such a manner as to fragment, in use the hard material of the front along at least one circular path centered onto the vertical axis, each impact hammer having a hollow casing, a pneumatically-operated, impact generating assembly enclosed within the casing, and a drill bit actuated by the impact-generating assembly. Advantageously, the hollow casings of the impact hammers are integral with the main body and form therewith a single structural piece, the central cavities of the hollow casings consisting of longitudinal holes made in this single piece and extending in directions substantially parallel to the vertical axis of a spindle at short distances from this axis. The drill bit of each impact hammer is preferably mounted in an upper sub-member screwed on top of the corresponding hole provided in the single piece, in such a manner as to be free to rotate therein. A torsion spring may be mounted externally around the upper sub-member in such a manner as to prevent inadvertantly unscrewing from the hole.      The main advantage of the above mentioned features is that they improve the life expectancy of the drill head and, more particularly, of its impact hammers.

IPC: C25B1/12
Filed: 1991-09-19
Abstract: Summary In pressure electrolysis cell equipment, water is reduced to hydrogen and oxygen  . The electrolytic cell block is contained in a pressure-resistant casing and is surrounded by an electrically non-conductive fluid which is maintained at the electrolytic operating pressure. Feed water and hydrogen are used as non-conductive fluids. Fluid pressure is controlled via the pressure of one or both product gases, e.g. via the pressure in the hydrogen separator. To set the starting temperature of the process, the fluid within the casing can be heated; during steady-state operation, indirect heat exchange results in cooling within the casing.
