Abstract: The system and method for forming an ignition sequencer comprising two inseparable portions (a body and an armature) where an armature is articulable with respect to a body to allow for the existence of no less than two distinct stages of the ignition sequence through the articulating motion of the additively-manufactured armature. The ignition sequencer assembly architecture allows for installation of an internal energetic compound while all components are assembled and interconnected. The ignition sequencer assembly architecture allows for installation into a next higher-level assembly using a single, uniaxial, force.

Abstract: Systems and techniques for a sensor platform for a geometric physical area are described herein. The sensor platform combines sensors installed in the physical area with transient sensors on people and articles within the area. This collaborative sensor data may then be used to identify interactions between people and articles and react by using these interactions to locate documents based on the person, the article, and the interaction within the geometric physical area.

Abstract: Systems and techniques for a physical marketplace interaction platform are described herein. A user may be identified. An article may be identified based on a physical relationship with the user. A user activity with respect to the article may be determined based on an observed context of the user and the article, and the user activity may be reported.

Abstract: An apparatus for wellbore fluid treatment having a body with a lower end, an upper end, an exterior surface and an interior surface defining a long bore open at the upper end, an outlet port spaced from the upper end, and a die in the long bore between the upper end and the outlet port. The outlet port permits the communication of fluids between the long bore and the exterior surface. The die is substantially immovable within the long bore and has an inner open diameter in which a plug is landable to create a seal in the long bore before passing through the inner open diameter.

Abstract: An apparatus and method for sorting ammunition casings and adapted to be mounted on a vibrating base. The apparatus includes an input hopper adapted to receive ammunition casings and a sorting track in communication with the input hopper where the sorting tracks has a graduated opening the bottom of the track such that the diameter of the graduated opening increases as the opening extends away from the hopper. The apparatus further includes sorting compartments arranged under the sorting track. Vibration moves the casings from the input hopper to the sorting track, and as the casings move along the sorting track, smaller diameter casings fall through a first opening portion into a first sorting compartment, and larger diameter casings move along the sorting track past the first opening portion and subsequently fall though a second opening portion into a second sorting compartment thereby separating the ammunition into different calibers.

Abstract: Multiple sensing configurations may be qualified based on one induced tachyarrhythmia, e.g., ventricular fibrillation, or other qualification event during an implantation procedure. Each sensing configuration comprises a different combination of two or more electrodes used for sensing electrical signals of the heart of the patient. In some examples, an implantable medical device or other device generates qualification information for each sensing configuration, which may indicate whether the sensing configuration is qualified for subsequent cardiac event detection based on an accuracy of the cardiac event detection for the sensing configuration during the qualification event. One of the qualified configurations may initially be selected as a primary sensing configuration for subsequent cardiac event detection. Switching to an alternate sensing configuration, e.g.

Abstract: An adjustable roof extension for a vehicle that has a cab portion and a trailer portion includes a roof extension adapted for disposition at a rear of a roof of the cab portion and an adjustment mechanism that attaches the roof extension to the cab portion such that the roof extension is pivotable and that an end of the roof extension that is nearer the trailer portion is controllably movable to pull an air flow over the cab portion toward the trailer portion.

Abstract: An improved method providing safety for young children being escorted from one point to another by adults. The method is non-tethering and non-restraining requiring only direction, to instruction-prone children to hold onto a ring. A number of Dual-Rings (4), forming a plurality of two-position entities, are slid onto a flexible, common center supporting line (2), through a hole in the Dual-Rings and held in place by Dowel Pins (8) which pass through the Dual-Rings and line. One Dual-Ring provides two positions and accommodates two children. The Dual-Ring spacing along the longitudinal axis of the center support line is appropriate to allow children to be escorted without companion interference. The individual ring spacing, of a Dual-Ring entity, is minimal, thus allowing the children to walk closely abreast to one another, in two columns, on narrow sidewalks prevalent in school/ preschool residential areas.

Abstract: A locking apparatus for use with surfboards and other articles which attaches to a cross bar on the article. The locking apparatus includes a member which surrounds the cross bar and a means for locking and unlocking the member to the cross bar thereby preventing unauthorized persons from removing the member from the cross bar. Used with a conventional surfboard, the lock apparatus advantageously attaches to an existing leash plug cross bar, requiring no modification or retrofit to the surfboard, and attaches without removal of a leash cord which likewise typically attaches to the cross bar. Further, a cable secures to the locking apparatus and is looped around or affixes to a generally stationary structure, such as an automobile surfboard roof rack, bicycle rack, post, etc., in order that the article cannot be moved without first unlocking the member.

Abstract: A circuit for interfacing switches to a component which allows the positions of the switches to be determined by the component. The component includes an input port and an output port. A switch network which is a parallel combination of two or more series combinations of a resistor and a switch is connected between the input and output port. A capacitor is connected between the input port and ground. The component determines switch positions by outputting a voltage on the output port and determining the time for the capacitor to charge to a predetermined value. Since each series combination has a unique resistance, the position of the switches therein can be determined in accordance with the capacitor charging time.
