Abstract: A replaceable needle assembly is provided for a retractable, prefilled syringe comprising a barrel having a mounting member and a plunger, whereby the retractable needle can be replaced by a user without affecting the retraction mechanism. The replaceable needle assembly comprises a needle fitted to a retractable needle mount and a needle retainer. The needle mount is removably, screw-threadedly mountable to the mounting member of the barrel. The needle retainer comprises a plurality of fingers that releasably engage the retractable needle to thereby prevent inadvertent retraction of the retractable needle before engagement by the plunger. The plunger comprises a plunger seal comprising an outer member and an inner member that engages the needle for spring-driven retraction. At the end of retraction, a lock is formed between the plunger and barrel to prevent re-use of the syringe.

Abstract: A replaceable needle assembly is provided for a retractable syringe comprising a barrel and a plunger, whereby the retractable needle can be replaced by a user without affecting the retraction mechanism. A mounting member is removably mountable to the barrel by way of a screw-thread connection and a needle mount is removably coupled to the mounting member. A needle is mounted to the needle mount. The barrel comprises a needle mount retainer that comprises a plurality of fingers that engage the retractable needle mount to prevent inadvertent retraction. The plunger comprises a collapsible seal which maximizes the efficiency of fluid delivery prior to the plunger engaging the retractable needle mount for retraction. An initially compressed spring decompresses to drive retraction of the plunger and the engaged needle mount. A lock formed between the plunger and barrel prevents further use of the plunger after retraction.

Abstract: A method of determining whether a user has complied with a service level agreement (SLA) with a network operator, comprising collecting a set of data values representative of the user's service usage and comparing the set of data values to the service level agreement. The data values collected provide the operator with sufficient information so that it can determine whether a SLA is being complied with and to plan provision of network services. A method of monitoring a user's usage of a network service and a service usage indicator is also disclosed.

Abstract: A method and system of adaptive power control. Characteristics of a specific integrated circuit are used to adaptively control power of the integrated circuit.

Abstract: A phase shift generation circuit has an edge detector, which receives an input pulse signal and outputs a first and a second edge signal denoting the time of occurrence of the first and second edges of the input pulse signal. The circuit also has a divide by N circuit, which receives a first clock signal and a group of signals representing a number N, and outputs a second clock signal, said a second clock signal having a frequency equal to the frequency of said first clock signal divided by the number N. The circuit further comprises a pulse counter, which receives the first edge signal and the second clock signal, and outputs a group of signals representing the number of the second clock pulses between occurrences of the first edge signal. The circuit has a first recycling timer, which receives the number of second clock pulses, the first edge signal and the first clock signal, and outputs a group of pulses approximating a uniformly spaced group across the time duration of the period of the input pulse.

Abstract: A method for controlling the power used by a computer including the steps of measuring the operating characteristics of a central processor of the computer, determining when the operating characteristics of the central processor are significantly different than required by the operations being conducted, and changing the operating characteristics of the central processor to a level commensurate with the operations being conducted.
