Title: Electrostatic discharge protection circuit for an integrated circuit
Inventor: SITCH JOHN E
IPC: H02H9/04
Filed: 1989-07-12
Granted: 1994-06-07
Abstract: ELECTROSTATIC DISCHARGE PROTECTION CIRCUIT FOR AN INTEGRATED CIRCUIT A terminal of an integrated circuit is protected from electrostatic discharge voltages at the terminal by a protection circuit which includes a bidirectionally conductive transistor as a discharge current shunting device. A bidirectionally conductive controlled path is provided between the terminal and one of two voltage supply terminals. The transistor has a biassing resistor connected between the terminal and its control electrode. A normally reverse biassed diode is connected between the control electrode and another of the voltage supply terminals. For an n-channel FET or an npn bipolar transistor, when a positive electrostatic discharge is applied to the terminal, a current flowing through the biassing resistor turns on the transistor to provide a discharge path from the terminal to the voltage supply terminal. When a negative electrostatic discharge is applied to the terminal, the diode is forward biassed and a resulting current flow through the biassing resistor turns on the transistor to provide a discharge path from the voltage supply terminal to the terminal. The transistor may be either a symmetrical bipolar transistor or an enhancement mode FET. An embodiment of the circuit for protecting a gallium arsenide integrated circuit (GaAs IC) uses an enhancement mode MESFET and a Schottky barrier diode. For an p-channel FET or a pnp bipolar transistor the polarity of the discharge is reversed.

Granted: 1994-01-04
Abstract: QUICK RELEASE SAFETY ATTACHMENT FOR A STIRRUP             Abstract of the Disclosure A stirrup for a horse riding saddle has a cylindrical bolt attached across its open end which, in a conventional fashion, rests in the bottom loop of a stirrup strap which in turn is attached to the saddle fender to hold stirrup in place. The bolt comprises a cylindrical sleeve with movable pins or rods having keyed outer ends extending axially out of the sleeve for engaging keyed openings at the open end of the stirrup and a spring within the sleeve applies a force to the pins to disengage them from the keyed openings while a greater and opposite force is applied by radially extending finger means to hold the pins in place.  If the stirrup swings in an arc with respect to the stirrup strap which exceeds a predetermined angle the force applied by the finger is disengaged from the pins so that the force of the spring takes over and disengages the pins from the keyed openings in the stirrups to allow the stirrup to fall free.

Granted: 1999-07-20
Abstract: A  dual  beam  moment-insensitive   load  cell   is hermetically sealed in a bellows or partial-bellows enclosure.          The enclosure may have convolutions over substantially its entire length which permits it to flex easily in the direction of load cell bending.   The enclosure is made resistant to elastic buckling under torsional forces produced by off-center loading  of  the load  cell  by  one  or  more  rods  spaced circumferentially about the enclosure and connecting together a  number  of  the  convolutions  after  the  convolutions  are aligned.  The alignment and torsional stiffening resist elastic buckling of the enclosure and resulting error in the output of the load cell.   Another form of enclosure has one or more convolutions at each end and joined by a relatively straight, non-convoluted wall which itself is resistant to torsional elastic buckling.   The resistance of the wall to torsional elastic buckling can be increased by increasing its thickness uniformly or by applying stiffener rods thereto.

Granted: 2002-03-12
Abstract: An infant environmental transition system and method provides an infant with a controlled, healthy transition from an intrauterine environment to the extrauterine environment, and includes a housing within which the infant is supported by a soft, form-fitting bed. Environmental conditions provided within the housing include simulated motions, sounds and tactile sensations resembling the intrauterine environment. A suspension and drive system controls the degree of movement imparted to the housing and to an infant supported therein.    The resulting motion closely approximates the motion experienced by the fetus while the mother is walking. The sound profile simulates intrauterine cardiovascular and gastrointestinal sounds. The system simulates day and night variations in motions and sounds, integrates changes to the environment over time toward the natural extrauterine environment, and may respond to infant activity or other imputs at various intervals.
