Abstract: A bicycle carrying frame includes a first part having a first bar and a neck link extending transversely and inclinedly from the mediated portion of the bar which is connected to the trunk lid by strips. A second part has a second bar and a connecting link intersectionally connected to the second bar. The first end of the connecting link is connected to the neck link and the second bar contacts against the rear bumper of the vehicle. A third part is connected to the second end of the connecting link and has two rings connected to two ends thereof so that the bicycle wheels are respectively supported by the two rings.

Abstract: A kinematic coupling for a test system with a test head which must be docked with a handling device. The coupling is implemented with a plurality of modules attached to the test head. Each module has one kinematic surface and is designed to mate with another kinematic surface on the handling device. Each module includes a motor which can extend or retract the kinematic surface. These modules allow docking of the test head to the handling device with a final motion perpendicular to the handler. They also allow the tilt angle between the test head and the handler to be adjusted to achieve planarization.

Abstract: A durable, rigid, low-cost device to sense an impact of a ball over a wide area and to provide response to a user that said impact has occurred. The sensing mechanism is a low-cost acoustic sensor, acoustically coupled to an essentially single sheet of plastic material. Sensor electronics filter the input and measure amplitude to determine if a valid hit has occurred. If so, the device reports an activate signal to the response electronics that in turn provide feedback to the user by playing a digitally recorded audio message, recorded specifically for the event. Variously, the activate signal may be transmitted to a remote device that contains the response electronics.

Abstract: An interface between a test head portion of automatic test equipment and a handling device such as a prober. The interface employs preloaded kinematic couplings between the test head and the handling device and between the probe card and the test head. These couplings allow the probe card to be repeatedly positioned relative to the component in the handling device. They also reduce forces on the probe card to prevent distortion of the probe card. The interface provides separate mechanical and electrical loops such that mechanical precision is not dependant on the electrical structure.
