摘要:
A metrological instrument for measuring surface characteristics such as surface form of a component (300). The instrument includes a slideway (32) to cause relative movement between a surface sensing probe (84) and the component which allows the probe to traverse a surface of the component. A probe carriage (80) supports the probe to allow the probe to move as a body in a measurement direction relative to the carriage so as to follow a surface being sensed. An optical sensor (82) provides a signal indicative of the displacement of the probe relative to the probe carriage. A controller (83) acts in response to a signal from the optical sensor, to move the probe carriage so as to maintain the probe in an operational range. A further sensor (11) measures measurement of displacement of the probe in the measurement direction as it follows a surface during use of the instrument.

A retractable step for use with a vehicle comprises a stepping member having an upper stepping surface, a first arm, and a second arm. The first arm has a first end pivotally attached to the vehicle, and a second end pivotally attached to the stepping member. The second arm also has a first end pivotally attached to the vehicle, and a second end pivotally attached to the stepping member. The first and second arms can be generally planar linkages.

A retractable step for use with a vehicle comprises a stepping member having a stepping deck, a first arm, and a second arm. The first arm has a first end pivotally attached to the vehicle, and a second end pivotally attached to the stepping member. The second arm also has a first end pivotally attached to the vehicle, and a second end pivotally attached to the stepping member.

An assembly for adjustment of the position of goggles with respect to a wearer's face can comprise a strap engagement member that is movable between a first position and a second position. When in the first position, the strap engagement member can be positioned or oriented to permit the goggles to rest against the face of a wearer. In the second position, the strap engagement member can be positioned or oriented so as to hold the goggles away from the face of the wearer.

A method and system are provided for reducing power amplifier induced distortion. Power amplifier induced distortion is iteratively estimated and cancelled. When the difference between the current estimated power amplifier distortion and the previous estimated power amplifier distortion is less than a convergence threshold, particular M-QAM constellation points that are still in error are determined A M-QAM constellation point correction routine is provided that can move the incorrectly estimated M-QAM constellation points that are in error towards their expected quadrants by generating updated M-QAM constellation points. The remaining estimated non-linear power amplifier induced distortion in the received signal can then be estimated and canceled.

A vehicle storage assembly can cover a vehicle storage area such as an interior console or a cargo box. The storage assembly can include a base and a lid. The lid can be opened from two sides to allow easy access for a driver and passengers to an interior storage compartment. The base includes at least two rods, which can act as axles for the lid to pivot about. The lid includes at least one rotation member or guide which can be released from the rod only when the lid is in a desired position, for example, a closed position. The lid can include a latch for each rod. The lid can have a lock to secure one or both of the latches with the lid in a closed position.
