Abstract: A method and system that monitors various functions and criteria within a standard vehicle platform (“SVP”) or a small engine platform (SEP?). The SVP uses an OBD-II adapter as a central controller to collect the information and communicate with a mobile communication device or a cloud based application to monitor the health of in-vehicle systems within the SVP and determine if maintenance is required. The SEP utilizes a run hour meter to collect information and communicates with a mobile communication device, an OBD-II adapter, or a cloud based application to monitor the health of an engine within the SEP and determine if maintenance is required. The method and system can automatically dispatch maintenance resources if maintenance is deemed necessary, thereby providing a managed maintenance solution for either a SVP or SEP.

The method further includes wirelessly transmitting a first plurality of data packets in series, wherein each of the first plurality of data packets includes one of a set of data packet identifiers and a portion of an update to software corresponding to the first software version identifier. The method also includes receiving, by the processor, at least one data packet acknowledgment and wirelessly transmitting a second plurality of data packets. The second plurality of data packets includes at least one previously transmitted data packet for which a data packet acknowledgment has not been received by the processor.

Abstract: A method is disclosed for determining the operating condition of a medical pump based on data derived from a pressure sensor and a position sensor. The pressure sensor generates pressure data by sensing the force on the pumping element. The position sensor generates position data by tracking the pumping cycle and determining the position of the pumping element. The pump pressure data and pump position data are processed and the calculated results compared with a pre-determined threshold value to determine the operating condition of the pump. The three main types of operating conditions of concern are the following: normal condition, where liquid is present and no leaks exist in pumping chamber; leak condition, where liquid is present but a leak exists in the pumping chamber; and air stroke condition, where the chamber contains some air.

Abstract: A medical pump, for use with a cassette having a pumping chamber, includes a pumping element with a piston slider assembly which intermittently pressurizes the pumping chamber during a pumping cycle and has a piston head connected to a main body with a single pressure sensor positioned there between. A camshaft is associated with the pumping element, an inlet control element, and an outlet control element for closing the pumping chamber to flow when the pumping chamber is pressurized. A processing unit receives pressure and position data from the pressure sensor and a position sensor associated with the pumping element, and processes this data to determine the operating condition of the pump. The operating conditions determined include: blocked fluid flow, no fluid in the line, no cassette associated with the pump, proper pump priming, or proper valve sealing.

Abstract: A hypodermic syringe includes a barrel with a plunger slidably extending therein. The barrel may include a barrel adapter at one end to define a luer hub socket and the outer walls of slots in the barrel. The plunger includes an outer plunger element and an inner plunger element telescoping together with a bungee resisting extension of the assembly. The inner and outer plunger elements may be locked in the extended position with the bungee in tension. A seal stop is located at the seal end of the plunger to define an annular pinch therewith to hold an annular seal in radial extension sealing against the internal sidewall of the barrel. A luer hub is fixed at the needle end of the barrel, A plunger cap may be advanced after injection to rotate the plunger. A resistance lock retains the cap and plunger indexed until actuation.

Abstract: A hypodermic syringe includes a barrel with a plunger slidably extending therein. The plunger includes an outer plunger element and an inner plunger element telescoping together. A plunger cap may be advanced after injection to rotate the plunger. A resistance lock retains the cap and plunger indexed until actuation. The rotation actuates latches and locking fingers on the luer hub to engage a probe axially and rotationally on the seal end of the plunger and disengage the slots in the barrel, respectively. The rotation disengages the seal stop to release the annular seal and finally releases the engagement between the outer plunger element and inner plunger element. The foregoing provides for the retraction of the luer hub and associated needle into the barrel.

Abstract: An air bag for use in connection with a gas generator is provided. The air bag is of a double-wall construction. The air bag is fitted to the housing of a gas generator and a gas jet opening for allowing the air bag to communicate with the housing is provided. A gas generated by the gas generator due to an impact is charged into the air bag. The air bag has a double-wall structure including a first air bag and a second air bag having a greater capacity than the first air bag disposed about and attached to the first air bag. The first air bag constitutes an air storage chamber which receives air from the atmosphere through an air intake path and stores the air. A gas storage chamber is formed between the first and second air bags which receives a combustion gas from the gas jet opening and temporarily stores the combustion gas. The air intake path is typically a hollow path between the atmosphere and the air storage chamber.

Abstract: A tube expander (10) for extrudably deforming tubes (12) into conformity with a flange (16) has a plurality of first and second forming members (28,30) circumferentially arranged on a mandrel (20). In an initial position, the forming members (28,30) are axially offset and radially retracted for ease of insertion into the bore (13) of the tube (12). After insertion, the mandrel (20) is partially withdrawn by an actuator (64) and by such action, the forming members (28,30) are brought together in an abutting, axially aligned, and radially expanded relationship such that workpiece-contacting surfaces (40,42) of the forming members (28,30) are brought into substantially continuous circumferential contact with the tube bore 13. The workpiece-contacting surfaces (40,42) are maintained in continuous circumferential contact with the tube bore 13 as the forming members (28,30) and the mandrel (20) are withdrawn from the tube end, thereby uniformly extruding the tube.
