InactiveUS6037733ASmooth and fast waferSmooth and fast and flat panel handlingProgramme-controlled manipulatorData processing applicationsSensor arrayRobotic arm
An improvement is set forth in a robotic arm structure which includes at least two links. theta motion is provided about a primary axis at the proximal end portion of the proximalmost of the links. R motion proceeds radially from the primary axis whereby the distal end portion of the distalmost of the links can be moved in a radially extending straight line. An end effector is pivotally mounted for rotation relative to the distal end portion of the distalmost link about an end effector axis which is parallel to the primary axis. The structure is improved by adding one or more a yaw motor, a roll motor and a pitch motor for rotating the wrist of the arm about the respective axes. A sensor array senses the R, theta , Z and yaw, roll and/or pitch motions and creates and transmits electronic signals representative thereof to a computer controller which monitors and controls the R, theta , Z and yaw, roll and/or pitch motions. Non-radial straight line motion and indeed, in certain embodiments any desired three-dimensional motion, is thereby enabled as is picking up of workpieces such as semiconductor wafers, flat panel displays and data storage disks, which are misaligned in cassettes or at workstations and/or are in cassettes which are misaligned and/or aligned and set up at an angle relative to the usual plane of operation of the arm.

Portable handheld exercise apparatus which can be attached to a multiplicity of body parts

The present invention is directed to a portable personal training and exercise device with a cable and pulley mechanism which also is a mobile personal training and exercise device having an ergonomic plastic external housing that with the use of straps fits in the hand as well as against different parts of the body. The present invention has a cable and pulley mechanism inside a housing which has a pulley rotatably mounted on a shaft that spins in only one direction. The pulley spins in both directions so that it is spring biased for rewinding a cord onto the pulley. Next to the pulley is a brake wheel or brake bushing that is attached to the shaft. The brake wheel or brake bushing and a pulley spinning on a single shaft inserts into a sealed ball bearing on both ends. A spring is connected to the bottom of the pulley. In the center of the pulley is a combination ball bearing/one-way clutch that turns the shaft only in one direction. The shaft is attached to the brake wheel or brake bushing. Secured around the outer edge of the brake wheel is a brake band. Secured around the outer edge of the brake bushing is a brake clamp. The brake band or brake bushing can be tightened for variable resistance through a tension adjustment assembly including a tension bolt. There is also a multi-directional guide unit mounted on the housing for allowing the pulley cords to be pulled in multiple directions with variable amounts of friction. The cord, which is wrapped around the pulley, emerges through a multi-directional bearing that rotates 360 degrees, thus allowing full range of three dimensional motion. Therefore, a user may pull the cords of the pulley for exercising various muscles of the user and adjust the resistance force of the cord at an appropriate level from the user. Different attachments can be connected to the snap at the end of the cord or cable such as a grip handle, wrist strap, waistband, ankle strap and foot strap.

A sports simulation system includes a projectile tracking apparatus having a display surface on which a visually apparent three-dimensional sports scene is presented. The projectile tracking apparatus captures images of a projectile tracking region disposed in front of the display surface to detect a launched projectile traveling through the projectile tracking region towards the display surface. A projectile launch area sensing unit captures images of the projectile launch area. At least one processing stage communicates with the projectile tracking apparatus and the projectile launch area sensing unit and is responsive to the data received therefrom to determine the three-dimensional positions, velocity, acceleration and spin of a detected projectile traveling through the projectile tracking region. The determined three-dimensional positions, velocity, acceleration and spin are used by the at least one processing stage to calculate a trajectory of the launched projectile into the visually apparent three-dimensional sports scene. Updated image data is generated by the at least one processing stage that includes a simulation of the launched projectile into the visually apparent three-dimensional sports scene following the calculated trajectory. A projection unit coupled to the at least one processing stage receives the image data from the at least one processing stage and presents the visually apparent three-dimensional sports scene, including the simulation, on the display surface.
