The invention relates to an oscillatory drive having an output shaft that can be driven to perform a rotationally oscillating movement about its longitudinal axis and that comprises a free end, a holding fixture at the free end of the output shaft comprising a contact surface for attachment of a tool, a mounting section on the holding fixture, raised relative to the contact surface, that projects to the outside in the direction of the longitudinal axis and that is designed for form-locking connection with a mounting opening of a tool placed in contact with the contact surface, and having a securement for fixing the tool with its mounting opening on the holding fixture, the securement permitting the tool to yield in axial direction under the action of a torque, against a pre-stress, and the mounting section permitting the tool to rotate by a certain angle of rotation when the tool gives way axially.

Various novel roofing brackets and roofing systems are disclosed. A first embodiment can be considered a roofing bracket to be coupled to a vertical post and a horizontal purlin of a roofing system whereby the horizontal purlin is positioned to support roof panels at a requisite pitch. The roofing bracket includes a reference brace and a clip. The reference brace includes a first brace face positioned planarly parallel with the vertical post and a second brace face extending at an angle angle from the first brace face and positioned planarly parallel with the vertical post. The clip includes a first clip face positioned to be fastened generally flush with the horizontal purlin and a second clip face extending at an angle from the first clip face and positioned to be fastened planarly parallel with the vertical post. The second clip face is coupled to the first brace face at a pivot point such that the clip can be rotated a particular angle relative to the reference brace. The angle of rotation is consistent with the requisite pitch of the roofing system.

A polarization-modulating optical element consisting of an optically active crystal material has a thickness profile where the thickness, as measured in the direction of the optical axis, varies over the area of the optical element. The polarization-modulating optical element has the effect that the plane of oscillation of a first linearly polarized light ray and the plane of oscillation of a second line early polarized light ray are rotated, respectively, by a first angle of rotation and a second angle of rotation, with the first angle of rotation and the second angle of rotation being different from each other.

An apparatus comprises a moveable arm for positioning an optical transducer adjacent to a storage medium, a stationary light source, and a moveable mirror mounted at a pivot axis of the arm for reflecting light from the light source to the optical transducer. An actuator can be provided for rotating the moveable mirror through an angle of about one half of an angle of rotation of the moveable arm.

In a handheld electronic device, a motor is controlled to adjust, according to input received at a user-input element of the device, an angle of rotation of a camera module about a rotation axis of the camera module. The camera module is partially embedded in a housing of the device. An image sensor is embedded in the camera module and senses an image in a field of view that is centered around a line of sight. The line of sight is perpendicular to the rotation axis. An orientation of the housing relative to a direction of gravity is sensed, and the motor is controlled to rotate the camera module and hence the line of sight about the rotation axis to achieve a particular angle between the line of sight and the direction of gravity.

An embodiment may comprise a camera based target coordinate measuring system or apparatus for use in measuring the position of objects in manner that preserves a high level of accuracy. This high level of measurement accuracy is usually only associated with more expensive laser based devices. Many different arrangements are possible. Other embodiments may comprise related methods of using a camera based target coordinate measuring method for use in measuring the position of objects. Many variations on the methods are possible. For example, a camera based coordinate measuring system for use in measuring the position of a target relative to at least one frame of reference without requiring use of a laser range finder for measuring distance may comprise at least three or more light sources located on a target wherein the light sources are located on the target at known three-dimensional coordinates relative to each other; at least one rotatable mirror rotatable on about a first axis and a second axis; a camera located to receive light emitted by the light sources that is reflected off the mirror; two angular measuring devices to measure the angles of rotation of the mirror about the first and second axes; and a processor for determining up to three positional degrees of freedom and up to three rotational degrees of freedom of the target.
