摘要： A system for infusing liquid to a body includes an infusion device, a network interface with a cell phone and wireless link and a network server system capable of communication with the infusion device through the network interface. The server system has access to a file of information specific to the controller for the infusion device. The infusion device includes a source of infusion fluid, a delivery port, a pump between the source of infusion fluid and the delivery port and a controller capable of programmable pump rate and sequence. A method for infusing liquid to a body includes controlling infusion using a programmable controller, establishing a file of information specific to the controller accessible to an extended area network server system and remotely transmitting commands to the controller. The information specific to the controller in the file is amended from a control terminal remote from the body. Operating instructions responsive to the updated information in the file are provided over an extended area network to a programmable two-way communication device. The device is capable of communication with the controller to forward operating commands. Requests for a bolus or a basal rate change are made through input to the two-way communication device which responds with commands transmitted over the wireless link to the controller consistent with the operating instructions from the server system. Network access through a monitoring terminal to the incidents of amending information specific to the controller is used for generating payments for the incidents of amending information specific to the controller accessed by the monitoring terminal.

摘要： A technique for establishing a tuning signal window for a multi-band VCO involves setting the tuning signal window to an initial size, preferably a relatively small size, and determining whether the VCO is churning. When the VCO is determined to be churning, the tuning signal window is expanded until the VCO stops churning. In an embodiment, the tuning signal window is expanded incrementally until the tuning signal window is large enough to include a solution, where a solution is defined as an operating point along a frequency band that satisfies both the setpoint frequency and tuning window signal requirements. The tuning signal window can be set at an offset relative to the tuning signal zero to compensate for shifts in the frequency bands that may result from changes in operating conditions.

摘要： The frequency changes in a bang-bang PLL that are generated using a digital phase detector's up/down signal are initially set to produce a faster pull-in rate and then reduced to produce a slower pull-in rate. The faster pull-in involves relatively large frequency changes and the slower pull-in rate involves smaller frequency changes. The changes in frequency of a bang-bang PLL can be implemented using a step size controller that includes timing control logic and step size logic. The function of the timing control logic is to control the timing of step size changes. The function of the step size logic is to set the step size of the frequency changes that are made by the VCO in response to the pd_up/down signal that is delivered directly to the VCO from the digital phase detector.

摘要： Centering a multi-band VCO involves comparing a VCO tuning signal to a pre-established tuning signal window to determine whether to change the frequency band of the multi-band VCO. The frequency band of the multi-band VCO can be changed only when the tuning signal is outside the tuning signal window. Further, the frequency band can be changed as long as the VCO is being controlled by a frequency detector. Once the multi-band VCO achieves lock, the multi-band VCO is changed by at least one more frequency band as long as the VCO tuning signal is still outside the tuning signal window.
