Patent CA-2136251-A1 (CA)
Title: Adjustable clip detection system
Inventor: PERSON ANDREW P
IPC: H03G3/30
Filed: 1994-11-21
Abstract: In an adjustable clip detection system, an audio output signal is sent from a volume control integrated circuit to an amplifier.  The output of the amplifier is received by a clip detection circuit.  The clip detection circuit monitors the audio output from the amplifier for clipping distortion.  If clipping is detected, the clip detection circuit sends a signal to a microprocessor.  The microprocessor then sends a signal to a volume control integrated circuit to decrease the voltage level of the audio output until clipping is no longer detected.  The amount of attenuation that the microprocessor instructs the volume control integrated circuit to perform is determined by a predetermined programmed parameter.  The amount of attenuation to be performed by the volume control integrated circuit can be adjusted by sending the microprocessor a formatted message, through a multiplex bus, corresponding to the predetermined program parameter located in a look-up table.

Title: Digital integrated circuits architecture
Inventor: SANZ GOMEZ RAFAEL
IPC: H03K3/012
Filed: 1994-12-29
Abstract: Specially used for reducing the current consumed by digital integrated circuits. For this, the bistables (B) incorporated in the digital integrated circuit are provided with a clock control input (CNTR) to enable or disable them. These bistables (B) are grouped into functional blocks (FB1,...,FBn) so that all clock control inputs (CNTR) from the bistables (B) of a given functional block (FB1,...,FBn) receive the same clock control signal (CNTR_1,...,CNTR_n) generated in a states machine (SM) as a function of a finite number of possible states in which it is possible to find the electronic equipment of which the integrated circuit forms part.      It is particularly applicable in integrated circuits that perform multiple tasks during an interval of time in a cyclic manner.

Patent CA-2141726-A1 (CA)
Inventor: BROWN LOUIS R
IPC: B60R21/21
Filed: 1995-02-02
Abstract: A method of inflating an inflatable vehicle occupant restraint (12) comprises the step of directing inflation fluid to flow into the restraint (12) to inflate the restraint (12) in a vehicle (11) between a vehicle seat (16) and a side portion of the vehicle (11), such as a vehicle door (18).  The inflation fluid increases the internal fluid pressure of the restraint (12) toward a maximum internal fluid pressure as the inflation fluid flows into the restraint (12).  The method further comprises the step of constraining the restraint (12) to resist inflating the restraint (12) during at least a portion of the step of directing inflation fluid into the restraint (12).  The step of constraining the restraint (12) causes the restraint (12) to reach a constrained volume at which the internal fluid pressure is approximately 70-100% of the maximum internal fluid pressure at approximately 6-8 milliseconds after the inflation fluid begins to flow into the restraint (12).

Title: Electrically operated slider release
Inventor: STANLEY PATRICK L
IPC: B62D53/06
Filed: 1995-05-30
Abstract: A rotary prime mover, preferably an electric motor,  is remotely operable from the cab of the vehicle.  A linkage couples the rotary prime mover to the pins of the slider assembly, wherein rotation of the rotary prime mover selectively moves the pin in and out registry with holes in a pair of rails on the trailer to prevent and permit relative movement between the rear tandem axle assembly and the trailer.  A pin sensor is coupled to the linkage to detect whether the pins are in or out of registry with the holes in the rails and a counter is coupled between the  rear tandem axle assembly  and the  trailer  to determine with which of the holes in the rails the pins are aligned.  A visual display is provided in the cab and coupled to the pin sensor and counter to communicate to the operator the registry of the pins and with which of the holes the pins are aligned.  The visual display in the cab includes visible, lighted indications of whether the pins are in or out of registry with the holes in the rails and whether pins are bound in the holes.          The visual display also includes a numerical counter to inform the operator with which of the holes the pins are aligned.  The visual display also includes audible and visual warnings to alert the operator if the slider release assembly is in one of several unsafe conditions.

Title: Apparatus and Method for Frequency Compensating an Operational Amplifier
Inventor: GILLIG STEVEN FREDERICK
IPC: H03F1/42
Filed: 1994-10-11
Abstract: A transimpedance circuit (201), and method therefor, frequency compensates an operational amplifier. The transimpedance circuit (201) has an input terminal (205) coupled to receive an amplified signal (205) and an output terminal (206) operative to produce a buffered amplified signal. The input terminal (205) of the transimpedance circuit (201) presents a resistive input impedance to the amplified signal at a frequency substantially near an open loop unity gain frequency of the operational amplifier (200). The amplified signal is buffered from a complex impedance of an input terminal (206) of an output driver (103). The present invention advantageously provides wide bandwidth and stable operation with loads having low complex impedance.

IPC: H01L21/265
Filed: 1994-02-14
Abstract: A high saturation current, low leakage, Fermi threshold field effect transistor includes a predetermined minimum doping concentration of the source and drain facing the channel to maximize the saturation current of the transistor.  Source and drain doping gradient regions between the source/drain and the channel, respectively, of thickness greater than 300.ANG. are also provided.  The threshold voltage of the Fermi-FET may also be lowered from twice the Fermi potential of the substrate, while still maintaining zero static electric field in the channel perpendicular to the substrate, by increasing the doping concentration of the channel from that which produces a threshold voltage of twice the Fermi potential.  By maintaining a predetermined channel depth, preferably about 600.ANG., the saturation current and threshold voltage may be independently varied by increasing the source/drain doping concentration facing the channel and by increasing the excess carrier concentration in the channel, respectively.  A Fermi-FET having a gate insulator thickness of less than 120.ANG., and a channel length of less than about 1µm can thereby provide a P-channel saturation current of at least 4 amperes per centimeter of channel width and an N-channel saturation current of at least 7 amperes per centimeter of channel width, with a leakage current of less than 10 picoamperes per micron of channel length using power supplies of between 0 and 5 volts.
