Title: Common-mode leakage error calibration for current sensing in a class-D stage using a pilot tone
Inventor: Ramin Zanbaghi
IPC: H03F3/217
Filed: 2021-04-20
Abstract: A system includes a modulator 34 and pilot tone injection circuitry (Fig.7, 78, 80). The modulator, which may include ramp generation circuitry 50 for generating a periodic triangular waveform VRAMP, generates differential pulse width modulation (PWM) driving signals PWMP, PWMN to drive an output stage 42. The output stage, which may be a class-D stage, is configured to drive a load (Fig.1, 6) as a function of the PWM driving signal. The pilot tone injection circuitry injects a periodic pilot tone into the PWM driving signals at a pilot tone frequency fPILOT, for example, by modulation of a common-mode offset ΔVCM of the periodic triangular waveform at the pilot tone frequency. A method of operating the system and an amplifier comprising the system are also provided. The periodic pilot tone may have a constant magnitude and may have a frequency significantly outside that of a frequency of a desired signal played back to the load. The system may comprise current sensing circuitry, including a sense resistor (Fig.1, RSNS) sensing current through the load, and measurement circuitry to capture an indication of common mode leakage of the sense resistor responsive to the periodic pilot tone.

Inventor: PRAKASH KUMAR NAYAK
IPC: A23N5/08
Filed: 2015-09-04
Abstract: An apparatus for separating the core from elephant apple fruit. Elephant apple is a complex fruit and it is hard, high in fibre and inside pulp contains gelatinous substances also the pulp is attach only with sepal in one side and it is very tight and hard. So, it is difficult job to remove pulp form sepal by direct sectioning. Based on the physical properties of the fruits the cutter was fabricated with fruit platform, fruit cutter die, fruit holder, force distribution • handle and frame. Two holder rings were placed in the instrument, one of them in the platform and another one placed above the platform at a defined distance. The purpose of placing two holder rings is to avoid the slipping of fruit as well as to avoid the upward movement of fruit during the operation. A movable fruit cutter die is placed at the top of the cutter, supported through two 3hafts which are attached to the platform. A handle (leaver) is attached to the cutter die which is a hand operated one. When the fruit is place in between the two holder rings, the fruit cutter die is operated with the help of the shaft (in the downwards) to bore into the fruit. When the fruit cutter die moved upwards, it carries way the core part of the fruit. Efficiency, loses has been compared with the traditional locally available cutter. The apparatus for separating the core from elephant apple cutter is affordable because of safety and user friendly as compare with other traditional cutting tools such as Knife and Boti. This apparatus is expected to have a lot of market potential in fruit beverage industry. Individual and industrial users would be relieved from the drudgery of extracting pulp which would lead to greater convenience and increased consumption. Further, it offers additional advantage of slicing other fruits and vegetables with hard outer cover.
