An implantable medical device is capable of delivering therapeutic output to a patient. A controller, programmable by a medical professional, is operatively coupled to the implantable medical device to, in part, program the therapeutic output to be delivered to the patient. The controller has an interface allowing the medical professional to graphically select an amount of the therapeutic output to be delivered to the patient in at least one of a series of discrete timer intervals. The graphic selection may be aided by the use of a light pen or other pointing device to sketch the infusion pattern. Computer programs using algorithms may be utilized to translate the information inputted through the light pen into an infusion program.

A control device is provided for controlling scrolling of a graphical object displayed on a computer monitor. The control device includes a housing; and a slider device disposed at a front portion of the housing configured to control scrolling of the graphical object on the monitor.

Distortion modeling produces distortion models for use by a distortion synthesizer to synthesize the harmonic distortion effects of audio distortion devices. A sinusoidal waveform is distorted by an audio distortion device and analyzed using a Fourier transform to produce a distortion model comprising harmonic amplitude and phase parameters. A phase correction process compensates for phase shifts induced by the audio distortion device. The distortion synthesizer uses a distortion function that distorts a digital audio signal according to the distortion model. The distortion model can be modified to alter the distortion effect and can be stored in a data-storage device for later retrieval. A frequency bandsplitter and signal mixer allow the distortion effect to be applied only to the low frequency content of the digital audio signal, thus providing spectral headroom to suppress the production of aliasing noise. Aliasing-noise suppression is provided for a full-bandwidth signal by up-converting the sampling rate of the signal before applying the distortion function and down-converting the sampling rate afterwards. A process is provided to remove the direct-current component that may be induced into the signal by the distortion function.

An optical signal power monitoring and control system is described. The system comprises at least one lasing SOA that receives, amplifies, and outputs the optical signal. During the signal amplification, a ballast laser signal is output through a substrate of the lasing SOA. This ballast laser signal is indicative of the output power of the lasing SOA. At least one detector converts the ballast laser signal to an electrical signal and transmits this electrical signal to a power monitor circuit. Using the electrical signal, the power monitor determines the output power of the lasing SOA. A pump control adjusts the rate at which the lasing SOA is pumped in order to change the saturation level of the lasing SOA and its corresponding power output ceiling. According to one embodiment, the power monitor identifies when the lasing SOA is approaching saturation or is saturated. If the lasing SOA is saturated or approaching saturation, the pump control increases its pumping rate causing the saturation level of the lasing SOA to rise. As a result, the lasing SOA is provided protection from saturation.
