Abstract: An unattended banking machine such as an ATM machine has a payment acceptor for accepting payment from the machine user and for determining the amount of payment from the user. A calculator determines the transactional difference between the amount of the transaction and the payment by the user. In ATM machines service fees may be charged to the ATM user for issuing a money order or for a wire transfer that are not in even multiples of the smallest denomination of the currency being dispensed by the ATM machine. The preferred cash dispenser has only bills of different denominations and no coins. To pay the transactional difference without the use of very small denomination currency and/or coins the transactional difference is divided into a cash payment portion which is dispensed in bills from the machine's cash dispenser.

Abstract: In a vibrating rotation sensor of the hemispherical resonator gyro type (HRG), operating in the whole angle mode wherein the standing-wave components are measured to provide a measure of the pattern angle, the digital signal processor functions to control the digital to analog converter output signal in order to keep the highly amplified analog to digital input signal, the difference between the pattern angle and excitation angle, within the analog to digital converter window. The analog to digital converter window is set at n times the discrete level of the digital to analog converter. A digital feedback loop in the digital signal processor continually corrects the tracking angle to control the excitation voltage.

Abstract: A blood containment device for use with a vascular entry needle provides visual and tactile confirmation that a blood vessel has been properly entered. The device includes a blood visualization chamber defined by a compliant member which provides a visual indication that a needle connected to the device has accessed a selected blood vessel. The blood visualization chamber is vented to allow air to escape therefrom as it is displaced by blood entering the visualization chamber, while a gas permeable membrane in communication with the vent to prevent significant blood from escaping from the blood containment device. A sealing member formed on an outer surface at one end of the compliant member works in conjunction with the gas permeable membrane to prevent significant leakage of blood from the device. The compliant member pulsates with changes in blood pressure, thereby providing continuous tactile confirmation that the needle tip is properly positioned within the selected blood vessel.

Abstract: A combination syringe and needle are disclosed wherein the needle assembly is mounted to a retractable element which retracts into the body of the syringe plunger. The needle assembly is mounted to the needle retractor which is spring biased to retract the needle. The retraction is actuated by releasing the forward end of the retractors from engagement with a collet positioned within the forward end of the syringe outer barrel. The collet is configured so as to clamp the forward end of the retractor and only releases the forward end when the collet is pushed forward, expanded, and disengages the forward end of the needle retractor. The pressure required to fully expand the collet causes the cap located on the forward end of the hollow plunger to collapse after being penetrated by puncture tabs formed on the collet base. The hollow plunger serves as a receptive container for the needle and hub forced into the syringe by spring biased upon release of the holder by the collet as it expands.

Abstract: A compact, lightweight closed coupling male spring lock fitting for direct connection to an air-conditioning hose having an inner sleeve, an outer sleeve and an annular cage, the inner sleeve having stepped portion that receives an inner surface of the annular cage. The annular cage surrounds the outer diameter of the inner sleeve and is spaced a distance from one end of the inner sleeve. The outer sleeve abuts an outer surface of the annular cage and prevents axial movement of the annular cage. The outer sleeve is retained in a retaining groove on the outer diameter of the inner sleeve, adjacent the stepped portion. The closed coupling of the outer sleeve and annular cage significantly reduces the overall length and weight of the fitting in comparison to prior art fittings and the inner sleeve may be machined opposed to conventional tube roll-forming processes.
