Abstract: A wear member includes a forward working portion that is disposed along its longitudinal axis including a closed end, and a rear attachment portion that is disposed along the longitudinal axis including an open end with an exterior surface, and an interior surface. The interior surface defines an interior counterbore with a major diameter, and a minor diameter. A ratio of the major diameter to the minor diameter ranges from 1.8 to 2.2.

Abstract: A spring loaded retainer includes a lug receiving portion defining a first maximum outside dimension, the lug receiving portion also defining a lug receiving slot that extends partially through the lug receiving portion, forming a first sidewall, a second sidewall, and a catch surface connecting the first sidewall to the second sidewall. A drive portion defines a second maximum outside dimension, and a first flat is disposed on the outside of the lug receiving portion proximate to the first sidewall or the second sidewall.

Abstract: A compact propane stove with an integrated roll table. The table surface stows rolled around the propane stove with the table legs inside the table.

Abstract: An improved emergency response system includes a set of databases which relates to volunteer responders and patients, which is controlled by a central system computer. The system interacts with patients and volunteer responders through a wireless network to patient and volunteer communicator devices. The emergency response system calculates and provides a compensation to the volunteer responders based upon their on-duty time, proximity to enrolled patients, and optionally based upon their performance during training and cardiac rescue events.

Abstract: A monitoring device for monitoring the readiness state of an automated external defibrillator (AED) and communicating the state to a remote receiver is described. The method uses a fault identification logic operable to detect an AED with a depleted battery. An associated method is described as well. The monitoring device captures both of a parameter related to the activation of the AED fault alert indicator and a second parameter that indicates a positive AED battery state.

Abstract: A defibrillator such as an automated external defibrillator (AED) includes a manual override feature which enables the AED to reduce the power consumption and owner annoyance after a self-testing fault. The AED, upon sensing a press of a manual override button or a receipt of an acknowledgement signal from a remote service provider, defers one or both of an alarm output and a subsequent self-test for a predetermined correction period. The deferral allows the user to correct the self-test fault during the correction period without further annoyance.

Abstract: A monitoring device for monitoring the readiness state of an automated external defibrillator (AED) and communicating the state to a remote receiver is described. An associated method is described as well. The monitoring device captures a non-acoustic parameter related to the activation of the AED readiness state beeper.

Abstract: An automated external defibrillator (AED) is described which includes two electrocardiogram (ECG) analyzers. One of the ECG analyzers is suitable for use only for ECG which is signal-noise-free, and thus may be used during “hands-off” analysis periods in which no cardiopulmonary resuscitation (CPR) compressions can be provided. The length of the “hands-off” analysis period can be shortened by use of the second ECG analyzer in concert with the first ECG analyzer. Thus, a greater proportion of CPR time through the course of a cardiac arrest rescue is achieved.

Abstract: An injector for injecting a reagent includes an axially translatable valve member positioned within a housing. An electromagnet is positioned within the housing and includes a coil of wire positioned proximate the valve member such that the valve member moves between a seated position and an unseated position relative to an orifice in response to energizing the electromagnet. A connector coupled to the housing includes an inlet tube concentrically aligned with and surrounding a return tube. The inlet tube is adapted to receive pressurized reagent from a source of reagent. The return tube is adapted to return reagent to the source.

Abstract: An injector for injecting a reagent includes an axially translatable valve member positioned within a housing. An electromagnet is positioned within the housing and includes a cylindrically-shaped coil of wire. The valve member moves between a seated position and an unseated position in response to energizing the electromagnet. A flux sleeve passes through the coil and includes two magnetic portions interconnected by a flux bridge portion or a flux break portion. Each of the magnetic portions is aligned with transverse planes defined by the ends of the cylindrical coil. The flux bridge portion or flux break portion is axially positioned between the transverse planes.
