An exercise machine has a frame with a generally rectangular base and a platform disposed at an angle at one end upon which the user stands. A horizontal shaft rotatably mounted on a pair of vertical frame members near the forward end of the base has an upper central sprocket at its center and smaller sprockets at its outer ends. A lower central sprocket is rotatably mounted on the base. A weight support arm pivotally connected to a pair of upright frame members extends forwardly therefrom and a selected number of weights are received on the outer end thereof. An elongate lift arm pivotally connected to the vertical frame members extends angularly upward and rearward therefrom toward the platform and has a pair of shoulder pads at its outer end positioned a distance above the platform, with a first and second pair of lateral hand grips near each end of the pads for griping the bar in two positions. A first chain wrapped around the upper central sprocket extends under the lower central sprocket and has its free end connected to the lift arm and a pair of second chains each wrapped around an outer sprocket in the opposite direction have their free ends connected to the weight supporting member. When the lift arm is raised by an upward force on the shoulder pads and / or hand grips, the lift arm pivots upward pulling the first chain down causing rotation of the upper central sprocket and outer sprockets which causes the second chains to pivot the weight supporting member upward with the weights at the outer ends thereof resisting the upward force applied to the lift arm.

A system, computer program product and associated methodology for video motion detection combines a series of images of a video sequence into an image volume having vertices of X, Y and t. The image volume is sliced in either the (X,t) or (Y,t) planes, filtered with a spatio-temporal filter and thresholded to reduce the amount of information. Then a search algorithm searches along search lines in a subset of the video sequence to locate motion. Motion can be detected by identifying lines that are not parallel to any of the vertices. Stationary subjects and lighting changes appear as lines parallel to one of the vertices. Thus, true motion can be distinguished from lighting changes.

A motion editing system for a robot in which the motion of a robot edited is corrected as the movements performed by an actual robot are checked. An optional range of motion data is reproduced using an actual robot. At this time, an output from each sensor mounted to the actual robot, that is, the sensor information, is transmitted to the motion editing system. The robot's movements are evaluated on the motion editing system based on the sensor information acquired during motion reproduction. If, as a result of the robot's movements, a predetermined evaluation criterium is not met, the motion correction processing is carried out. If the predetermined evaluation criterium is met, a motion data file, in which is embedded the reference sensor information, is formulated.

A robot system efficiently performing an operation of moving a robot to close to and / or separate from a target point, such as teaching operation. A camera of a visual sensor is mounted to the robot such that a distal end of an end effector is seen within the field of view of the camera, and the end effector's distal end and a target position on an object are specified on a monitor screen. When an approach key is depressed, a target position is detected on an image, and a difference from a position of the end effector's distal end is calculated. Whether the difference is within an allowable range is checked. Depending on the result, an amount of robot motion is calculated, and the robot is operated. The processing is repeated until the depressed approach key is released. When a retreat key is depressed, the robot moves away from the object. The robot may be caused to stop using a distance sensor.

Array hybridization can be facilitated by agitating a reaction cell subject to centrifugal force greater than 1 G. A two-dimensional hybridization array is preferably oriented generally orthogonal to the centrifugal force. Agitation involves titling the array back and forth about an axis, preferably parallel to a centrifuge axis. The centrifugal force serves, in a sense, as supergravity helping to overcome non-specific binding forces (viscous forces and other forces at the liquidsolid boundary) that limit the rate of liquid flow. Thus, the agitation rate and the related replenishment rate can be increased. The agitation causes the sample liquid to wash back and forth across the array, which remains protected by a thin liquid film. The resulting “tidal” motion, results in thorough mixing of the sample liquid. In addition, since only a thin film is required over much of the array, typically costly sample volume can be reduced. Thus, faster hybridization with lower sample volumes can be achieved.
