Provided is a calibration apparatus, including: a holder for fixing an electronic device; a first motor for rotating the holder with a first rotation axis as a center; a second motor for rotating the holder with a second rotation axis perpendicular to the first rotation axis as a center; and a stopper for restricting a rotational position of the holder about the second rotation axis to a range between a reference position and a perpendicular position reached by rotating the holder by 90 degrees from the reference position, in which the first motor rotates the holder to which the electronic device is fixed at a predetermined speed in each of states in which the rotational position of the holder about the second rotation axis falls in the reference position and in which the rotational position of the holder about the second rotation axis falls in the perpendicular position.

A technique to assess or analyze cap removal or opening torque or rotational position is provided. In at least one form, a high speed, on-line machine vision system measures or determines the rotational position of a cap on a bottle, measures or determines the rotational position of the finish or neck of the same bottle, and then optionally uses such positional information to predict the opening or removal torque that will be required for a consumer to remove the bottle cap from the bottle.

An electric tool is provided. The electric tool prevents anomalies in motor rotation due to dust and moisture sucked in together with a cooling wind, and is configured such that rotational position detection operations and switch operations are not affected. In the electric tool which drives a brushless DC motor using a controller, a magnetic body for rotational position detection is provided on a rotation shaft which can rotate integrally with a rotor, Hall ICs are provided to detect the rotational position of the magnetic body and output a position signal to the controller, and the magnetic body and the Hall ICs mounted on a substrate are arranged in a region isolated from the wind path of the cooling wind generated by rotation of a cooling fan. The Hall ICs are accommodated in a housing filled with resin.

A handle for controlling a power tool by configuring the handle in either a straight or T-shaped position. In the straight position, the handle design serves as a rotational safety control that allows a user to control the rotational reaction of the tool by placing the user's hand in a position that is perpendicular to the main body of the tool. In the T-shaped configuration, the user can apply rotational force and longitudinal force more easily because the hand position is tangent to the tool base. A fastener couples a base of the handle to a band that grips the power tool and facilitates the user control.

A pointing device and method for providing both translational and rotational input to a computer, to manipulate graphical objects. In one embodiment, a pointing stick is cantilevered to a base. One or more translational sensors are coupled to the pointing stick to generate translational signals in response to lateral forces applied to the pointing stick. One or more rotational sensors are coupled to the pointing stick to generate rotational signals in response to rotational forces applied to the pointing stick. The rotational sensor may sense torque, such as with a piezoelectric sensor configured to detect rotational strain on a fixed pointing stick. The rotational sensor may alternatively sense rotational displacement, such as with a potentiometer configured to detect rotation of a rotatable sleeve about a fixed shaft.
