Title: Passive Restraint System for a Vehicle Occupant Using an Air Bag
Inventor: IKEYA AKIHIRO
IPC: B60R21/2165
Filed: 1994-10-11
Abstract: ABSTRACT OF THE DISCLOSURE      In a passive restraint system for a vehicle occupant using an inflatable air bag, an open base end of the air bag is clamped between an air bag housing for accommodating the air bag in its folded state and an inflator housing for receiving an inflator for producing the inflating gas therein.  Thus, the base end of the air bag can be attached securely and tightly to the air bag system in a highly simple manner.  The air bag housing diverges toward the opening for deploying the air bag, and the air bag can be therefore rapidly deployed without encountering any substantial resistance from the air bag housing.  Also, the diverging shape of the air bag housing allows the air bag housing to be laterally deformed to absorb the energy of impact applied thereto.

Title: Content-addressable memory with programmable field masking
Inventor: LIN HORNG-DAR
IPC: G11C15/04
Filed: 1994-06-22
Abstract: CONTENT-ADDRESSABLE MEMORY WITH PROGRAMMABLE FIELD MASKING          Abstract An apparatus and method for programmable field masking in content-addressable memory (CAM). The present invention provides a CAM with at least one group of memory cells interconnected by a word line and a match line.  The group of memory cells includes data memory cells divided into a number of data memory cell fields for storing data bits of a data word.  A mask memory cell is provided within the group of memory cells for storing at least one mask bit indicating a status of data stored in at least one of the data memory cell fields.  The mask memory cell is operative to interrupt the match line in response to the stored mask bit.  A match line detector detects a signal level on the match line to indicate if input data bits supplied on the data memory cell bit lines match data bits stored in at least one of the data fields.  The data memory cell fields may be organized into a hierarchy, with mask memory cells connected between the data fields, to provide hierarchical masking.  General programmable masking of any data field within the group is provided using multiplexed mask memory cells connected by bypass lines.  The multiplexed mask memory cells may store one or more mask bits in order to allow a bypass line to be connected to portions of the match line, thereby masking a given data memory cell field.

Title: Replaceable Closure System
Inventor: HUNTER JOHN
IPC: B65D39/08
Filed: 1994-06-22
Abstract: A drum closure system is provided for protecting the integrity of the threads of a drum neck and for providing the safe and easy installation of a replaceable closure neck.  The drum closure system primarily comprises a drum with a drum neck integrally formed in the drum top, a closure plug, a replaceable closure neck which is interposed threadably between the drum neck and the closure plug, and a specialized tool for installing and removing the replaceable closure neck.   The use of the tool, which is designed to enable exertion of very high levels of torque on the replaceable neck, eliminates the need for a locking mechanism between the replaceable neck and drum neck because insertion of the replaceable neck at a high torque measurement virtually eliminates the possibility of relative rotation of the replaceable neck without the specialized tool.  Installation of the closure plug makes the removal of the replaceable neck virtually impossible.

Abstract: A facility is provided in an ATM network to track whether data traffic from a source is being admitted into the network in accord with associated traffic parameters. Such parameters are used to control the admission of traffic and aredynamically changed based on the level of congestion along an associated connection carrying such data. The level of congestion along the connection is determined by launching a particular type of cell over the connection and waiting to see if the destination and intermediate points along the connection return the cell to the sender, thereby indicating that the route of the connection is not congested. If the cell is not returned, then the facility concludes that the route is congested.
