Abstract: Some embodiments provide a system to facilitate delivery of insulin to a patient. An insulin adjustment platform may include an input port to receive current blood glucose data, associated with the patient, from a continuous glucose monitoring unit. A camera may capture an image in substantially real time, and an adjustment engine may receive the current blood glucose data along with the captured image. An artificial intelligence algorithm may identify at least one probable food item within the captured image and automatically determine and display a default carbohydrate parameter associated with the at least one probable food item via an augmented reality interface. The system may interact with the patient via the augmented reality interface to adjust the default carbohydrate parameter and transmit data associated with the adjusted default carbohydrate parameter to an insulin delivery unit associated with the patient.

Abstract: Method for enabling use of the same, existing test programs for both an obsolete and new waveform digitizer, each having an analog input interface and a digital output interface, entails providing an automatic test equipment for hosting test programs for using a waveform digitizer, and determining scalers and low voltage monolithic analog-to-digital converters to couple to the analog input interface and digital output interface of the new waveform digitizer. As such, the new waveform digitizer provides the same function, or has the same functionality as, as the obsolete waveform digitizer, and the same, existing test programs can be used for the new waveform digitizer as were used for the obsolete waveform digitizer.

Abstract: Method for replacing Electron Bombarded Semiconductor (EBS) tubes in a waveform digitizer having an analog input interface and a digital output interface, the EBS tubes being interposed between the analog input interface and the digital output interface, in which the EBS tubes and associated circuitry and componentry between the analog input interface and the digital output interface are removed, scalers and low voltage monolithic analog-to-digital converters (ADCs) are coupled to the analog input interface and the digital output interface. The ADCs may be mounted on a printed circuit board. The ADCs and associated circuitry may be designed to provide on-chip calibration and a built-in testing ability.

Abstract: System for testing attenuators by a flatness and standing wave ratio tests which includes a vector network analyzer (VNA) adapted to be coupled to a device under test (DUT) and which provides an input stimulus signal for the DUT and, when certain conditions are satisfied, receives an output signal from the DUT, and a calibration receiver adapted to be coupled to the DUT via a down-converter. When certain conditions are satisfied, the output signal from the DUT is sent to the calibration receiver (through the down-converter to be possibly modified thereby depending on the testing frequency). A signal generator provides a local oscillator (LO) signal for the down-converter. A control unit is connected to the instruments and embodies software which analyzes the testing conditions, i.e., the attenuator value being tested, and selects whether the network analyzer or the calibration receiver will measure the output signal from the DUT.

Abstract: A method for generating a waveform at a particular frequency in which a segment RAM depth is determined based on the relationship between the frequency and a variable clock value, a RAM based memory system is provided with waveform information, and the waveform is sequentially generated from a combination of the waveform information in the RAM based memory system from a first memory site to a memory site dependent on the segment RAM depth. The generated waveform is filtered to obtain only the waveform at the desired frequency. The RAM based memory system is provided with the waveform information by dividing each desired waveform into segments depending on the clock value and storing each segment in a respective memory site. An analog to digital converter may be evaluated by directing the desired waveform to the analog to digital converter. The generated waveform is tuned in the filter to a center frequency if it is a sinewave or a tuned squarewave.

Abstract: An improved circuit for phase noise measurements utilizing a frequency down conversion/multiplier and direct spectrum measurement technique. The circuit is particularly useful for field test environments where laboratory instrumentation is normally not available, and fast and accurate phase noise measurements are required. The phase noise measuring circuit includes a frequency mixer which has a first input signal from a device under test and a second input signal from a reference stable oscillator having ultra low phase noise with a fixed center frequency. The frequency mixer produces a down converted signal comprising the frequency difference signal of the first and second input signals. A lowpass filter passes the down converted signal to a frequency multiplier circuit which produces a second harmonic signal, a fourth harmonic signal, and higher harmonic signals of the down converted signal.

The circuit is particularly useful for field test environments where laboratory instrumentation is normally not available, and fast and accurate phase noise measurements are required. The phase noise measuring circuit includes a frequency mixer which has a first input signal from a device under test and a second input signal from a reference stable oscillator having ultra low phase noise with a fixed center frequency. The frequency mixer mixes the first and second input signals to produce a down converted signal comprising the frequency difference signal of the first and second input signals. A lowpass filter then passes the down converted signal to a frequency doubler circuit which produces a doubled frequency, down converted signal.
