Rotating the tool as a whole directly rotates the tool shaft, while rotating only the adjustment shaft causes the reducer to apply a smaller rotation to the tool shaft according to a reduction factor that can be between 16 and 1024. The adjusting element can be a manually rotated knob, or a motor, such as a stepper motor, actuated by a switch, such as a momentary contact, rocker, or pushbutton switch. The reducer can include one or more planetary gear stages, and/or one or more strain wave gear stages. The tool can have a length not more than 5 inches and a diameter not more than 0.6 inches.

Abrégé

A monobit analog-digital converter (ADC) system and method are disclosed, the system comprising a front-end signal conditioning system equipped with a programmable attenuator and amplifier for processing analog signals, where the attenuator, which may include a cascade of programmable attenuator cells, is controlled by an attenuation control signal to adjust signal attenuation to cause a signal-to-noise ratio (SNR) in the negative domain, after which an amplifier amplifies the attenuated signal with the suitable SNR, where the amplified signal is then converted to a monobit signal by a monobit ADC, thereby achieving an ADC system that enables conditioning and digitizing of RF signals over a wide range of input signal powers with control over the output spectrum signal power and harmonics to achieve low-power real-time general-purpose broadband blocker detection for adaptive radios and for interference detection, main beam radar signal detection, and instantaneous frequency measurement, among other fields requiring general-purpose blocker identification with low size, weight, power, and cost (SWaP-C).
