Title: Emergency signal warning system
Inventor: BERNSTEIN BERNARD
IPC: G08B1/08
Filed: 1988-07-19
Granted: 1993-11-09
Abstract: ABSTRACT   A siren detection system is particularly suited for installation in an automobile for providing a warning to the driver when an emergency vehicle is in the vicinity of the automobile.  The system includes a microphone mounted on the automobile.  The output of the microphone is supplied to a bank of band-pass filters, each tuned to a different adjacent portion of the frequency range through which the frequency of a siren varies.  The outputs of the filters are sampled by an averaging and  selection  circuit which produces  a  single  output corresponding to the central one of any of the filters producing an output during a preestablished time interval.  This output then is compared with the previous output (which indicates the previously selected band-pass frequency) to operate an up/down counter.  Whenever successive counts of a preestablished number in the same direction occur, the output of the counter enables an alarm to indicate the presence of a siren operated by an emergency vehicle in the vicinity of the automobile.  This system inherently rejects noise in the same frequency range,  since random noise signals do not produce the necessary successive output counts from the counter to activate the alarm.

Abstract: EXPOSURE CONTROL SYSTEM FOR DUAL MODE        ELECTRONIC IMAGING CAMERA                   ABSTRACT OF THE DISCLOSURE      A method and apparatus for exposure control of electronic imaging cameras capable of video and still modes  of  operation  and having an automatic variable aperture diaphragm to control image light passing to a sensor during the video mode of operation.   Relatively short exposure time intervals are attained in the still mode of operation by attenuating light passing to the sensor during the video mode so that the aperture to which the variable aperture diaphragm is set is  in-creased over that to which it would normally be adjusted during video operation.   Upon conversion to the still mode, the filter attenuation is rapidly removed result-ing in a correct aperture setting for the relatively shorter still mode exposure time intervals.   In the video mode, electronic shutter operation is effected in the conventional manner.   In the still mode of opera-tion, the exposure time interval is established either by a combination of electronic shutter operation and mechanical shutter operation or by mechanical operation alone.   A shutter mechanism is disclosed in which the light attenuating and exposure terminating functions are combined.

Title: Context switching method and apparatus for use in a vector processing system
Inventor: BHANDARKAR DILEEP P
IPC: G06F9/46
Filed: 1989-03-17
Granted: 1993-04-27
Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to a method and apparatus to minimize the time a data processing system spends on saving and restoring vector processor state data during a context switch.  A context switch occurs when execution of an old process is suspended and execution of a current process is begun.  The vector state data associated with the old process remains in the vector processor until the current process attempts to execute a vector instruc-tion.  When this occurs, the vector state data associated with the old process is saved and vector state data associated with the current process is restored, if the old process is not the same as the current process.  If the old process is the same as the current process, there is no need to save and restore any vector state data.

Filed: 1989-06-05
Granted: 1993-04-27
Abstract: ABSTRACT OF THE DISCLOSURE         A combination retractable needle cannula and cannula lock which is to be interfaced with a prefilled medication carpule at the cylinder of a conventional hypodermic syringe.  The cannula lock includes a clamp having a pair of oppositely disposed jaws which are normally separated from one another so that the needle cannula can be releasably retained therebetween.  In the pre-injection state, the jaws of the clamp are surrounded by and rotated towards one another by an expandable outer sleeve so as to retain the cannula in an axially extended position between the jaws for administering an injection.  In the post-injection state, and after the contents of the carpule have been expulsed via the cannula, the clamp is displaced by the carpule outwardly of the sleeve, whereby the jaws of the clamp are free to rotate away from one another to release the cannula.  The cannula may then be retracted within and completely surrounded by the empty carpule so that the cannula can be safely discarded after use while avoiding an accidental needle stick and the spread of a contagious, and possibly life threatening, disease.
