US Patent:

6746131, Jun 8, 2004

Filed:

Feb 11, 2002

Appl. No.:

10/073736

Inventors:

Steven G. Goldstein - Marina Del Ray CA 90292
Mark R. Barton - Los Angeles CA

Assignee:

Steven G. Goldstein - Marina Del Ray CA

International Classification:

F21V 3300

US Classification:

362 96, 362 86

Abstract:

A transparent container has two immiscible liquids of different densities, colors and viscosities. A pump with a magnetic coupling injects the denser liquid upwardly into the less dense liquid in response to changes in sound volume or frequency of the vicinity of the device providing a geyser display reactive to music or voice. Pump control circuitry includes a microphone, an amplifier; a filter for extracting a beat from dance music or syllabic content of speech; an amplitude detector for detecting a short-time amplitude envelope; a long time averager providing a reference signal proportional to the average sound level and an attenuator; a comparator connected to both the averager and the attenuator to change state when the attenuated version of the short time amplitude envelope momentarily rises above reference signal to provide an activating signal to a pump power controller causing electric power to be delivered to the pump.

Appl. No.:

10/850340

Inventors:

Mark R. Barton - La Canada Flintridge CA, US
John Ross - La Canada Flintridge CA, US

International Classification:

G09B 23/28

US Classification:

434266

Abstract:

A simulated part of the human vocal tract above the glottis is formed as a resiliently flexible, cylindrical tube with a wall of sponge/foam saturated with water and covered by a thin, flexible water retaining skin. The wall can also be a gel or skin balloon filled with water or oil. A speech simulator has a buzz generator formed by an air compressor, accumulator and regulator supplying air to an chamber filled with sound absorbing batting and having a tubular outlet connected to an inlet end of the tube and covered by a valve simulating a glottis and vocal chords and formed by a rubber membrane slit to provide two flaps controlled by respective pen motors. the tube can be constricted manually to provide various animal and human vocal sounds.

International Classification:

E05B 4700

US Classification:

2922515

Abstract:

The touch bar release locking system includes a hollow metal channel which affixes to a door at two points via insulating spacer blocks. Within the channel is housed a capacitive sensor which functions by detecting the additional capacitance coupled to the hollow channel by the act of a person touching it (even through gloves or clothing). When the additional capacitance is detected, a relay energizes and actuation of the relay contacts releases an electric lock which had been securing the door, thereby providing free egress. In the event of catastrophic sensor failure, egress can still be accomplished by pressing an electromechanical push button, mounted on the rear of the hollow channel, which duplicates the effect of energization of the sensor relay.
