Abstract: In a method of converting an analog signal to digital format, an analog input signal is received and processed using sigma-delta modulation to provide a first digital signal that represents the analog input signal in digital format and to provide a second digital signal that represents a first error introduced during the sigma-delta modulation. A second error that is error introduced during the sigma-delta modulation is estimated. A pre-correction signal is determined based on the first and second digital signals. A difference between the estimated second error and the pre-correction digital signal is determined to provide a digital output signal representing the analog input signal in digital format. An error correction element operable to adjust the digital output signal based on the analog input signal, the digital output signal, and the second digital signal is controlled.

Abstract: A rechargeable type callus removal instrument is disclosed, that includes a main body having a flaring tube shape with one side opened. The instrument can include a callus storage fitted around the motor shaft of an internal motor that rotates with rotation of the motor shaft, thereby collecting calluses separated from a user's foot therein. A filing cap can cover an upper surface of the callus storage for removing calluses on the user's foot while rotating with the callus storage in contact with a callus surface of the foot. A guide member can be included to assist with forming an exterior barrier such that the calluses being removed by the filing cap are collected in the callus storage without scattering about to the outside. The callus removal instrument enables callus removal using a rotational force of a motor through electric recharging with an improved portability while preventing water infiltration.

Abstract: A method and system for aligning robotic wafer transfer systems provides a wafer cassette having one or more wafer slots having portions covered with an electrically conductive material and a sensor that is in electrical communication with the electrically conductive material. When a wafer is loaded into a wafer cassette such as may be contained within a wafer transfer module such as a FOUP, an indication of position is delivered to the sensor which detects the alignment and indicates if the loaded wafer undesirably contacts either or both of the opposed grooves that form the wafer slot of the wafer cassette. An indication of the wafer's position may be provided from the sensor to a controller that delivers a signal for aligning the wafer transfer blade of the wafer transfer robot responsive to the signal indicative of position.
