Title: Target bubble generation and target shooting system
Inventor: LA FATA JOHN E
IPC: F41B9/00
Filed: 1991-08-28
Abstract: TARGET BUBBLE GENERATION AND TARGET SHOOTING SYSTEM                               ABSTRACT      Target bubble generating and target shooting systems (50, 50A, 50B, 50C) are disclosed employing a target bubble generator housing (59), a pair of left and right actuating handles (51, 55) pivotally coupled at their front ends to the left and right vertical edges of the housing (59), and a bellows assembly (116) positioned intermediate the left and right handles (51, 553 and coupled to the latter at the approximate midpoints thereof.  The target bubble generating housing (59) includes a torus-shaped reservoir (81) and a vertically reciprocable bubble wand (98) having a film-forming elliptical ring structure (101) including upper and lower serrated arcuate edges (102, 104) of truncated triangular cross section to minimize disturbance of the soapy fluid in the reservoir (81) as the bubble wand (98) exits the fluid.  The bellows assembly (116) generates three positive pressure airstreams during compression--one to lift the wand (98) out of the film-forming solution, one to strip the soapy film from the wand (98) to. form and project target bubbles (60), and one to actuate an audible sound generator (127).  During expansion, the bellows assembly (116) creates a negative pressure condition which serves to affirmatively retract the bubble wand (98).  The twin actuating handles (51, 52) which are manually manipulated to compress and expand the bellows (58) serve as water ejectors capable of projecting one or two high pressure water streams (61) along parallel, convergent or divergent trajectories to enable shooting down target bubbles (60).

Patent CA-2070712-A1 (CA)
Title: Self calibrating pulse width modulator
Inventor: GIRMAY GIRMAY K
IPC: H03M1/10
Filed: 1992-06-08
Abstract: A circuit for producing an exact duty cycle for a system having a variable system clock frequency. In the calibrate phase, a waveshape with an exact duty cycle is made by ANDing two or more clock pulse trains, each of which is a multiple of the system clock frequency.  This is compared against the output of a current-controlled pulse width modulator (PWM) which is programmed to produce the same duty cycle. The polarity of the comparator output as a result of the error between the exact duty cycle and the one produced by the modulator increments or decrements a counter, the output of which controls a digital-to-analog converter (DAC), which in turn corrects the output of the modulator.  After a suitable number of interactions, the modulator, which is not calibrated, will reproduce the exact duty cycle.  The circuit is then put into the operate mode by disabling the counter, and programming the pulse width modulator to output the desired system duty cycle.  The circuit may be used anywhere that a pulse width modulator exists in a digital system and must be calibrated accurately.  It may be used in a laser printer, for example.
