    Abstract: A rowing exercise device includes: a pair of pedals; and a device body that guides the pair of pedals in such a way that the pair of pedals repeatedly move along a predetermined trajectory. A user performs a lower limb exercise by putting his/her feet on the pair of respective pedals. Each pedal is configured in such a way that a relative roll turn of a forefoot part relative to the device body is prevented while a relative roll turn of a rearfoot part relative to the forefoot part is allowed, whereby a relative roll turn of the forefoot part relative to the rearfoot part occurs during the lower limb exercise.

    Abstract: The present specification provides a technique for accelerating solidification of a liquid gasket. A cooler disclosed herein comprises a main body, a cover, a pair of first fins, and second fins. A channel through which refrigerant flows is formed in the main body. The cover is attached to the main body to close the channel with a liquid gasket. The first fins are arranged on the main body or the cover, and each of the first fins extends along a refrigerant flow direction and facing corresponding one of inner side surfaces of the channel. The second fins are arranged between the pair of first fins. A height of the first fins is smaller than a height of the second fins. The first fins having the smaller height allows larger amount of the refrigerant flowing by the liquid gasket, and thus the liquid gasket efficiently absorbs water and quickly solidified.

    Abstract: Systems and methods for performing three-dimensional multi-object tracking are disclosed herein. In one example, a method includes the steps of determining a residual based on augmented current frame detection bounding boxes, augmented previous frame detection bounding boxes, augmented current frame shape descriptors, and augmented previous frame shape descriptors and predicting an affinity matrix using the residual. The residual indicates a spatiotemporal and shape similarity between current detections in a current frame point cloud data and previous detections in a previous frame point cloud data. The affinity matrix indicates associations between the previous detections and the current detections, as well as the augmented anchors.

    Abstract: A technique disclosed herein relates to a method for producing a plate piece including a partial outline and a remaining outline continuous from the partial outline. The method disclosed herein may comprise removing an outer region external to the partial outline from a plate workpiece by a first punch (first punching process); and punching out an inner region internal to the remaining outline by a second punch from the plate workpiece in which the outer region has been removed while applying a block to a side surface of the plate workpiece along the partial outline (second punching process). In the second punching process, by applying the block to the side surface of the already-formed partial outline, deformation of the partial outline can be suppressed when the inner region internal to the remaining outline is punched out by the second punch.
