Abstract: Time-resolved emission can be used to measure loop-synchronous, small-signal voltage perturbation in integrated circuits. In this technique the measurements are completely non-invasive and so reflect the true device behavior. The time-dependant propagation delay caused by Vdd modulation also shows the expected qualitative signature. This technique should find applications in circuits with relatively fast clock-like circuits where loop-synchronous voltage pickup is limiting circuit behavior.

Abstract: A beacon circuit enabling study of active elements in an integrated circuit is disclosed. The beacon circuit may be integral to a DUT to be tested. The DUT is stimulated by a conventional ATE, so that its active devices are operating. The signal from the active device is sent to the beacon circuit which, in response to the signal, emits light having intensity that is proportional to the value of the signal. In one example, the beacon circuit is constructed as a voltage to current converter having its input connected to the node of interest and its output connected to a current to light converter. In one example, the current to light converter is implemented as a current mirror circuit. One beneficial implementation disclosed is the use of the beacon circuit for the study of voltage supply disturbances.

Abstract: In an adjustable trailer hitch device, a shank is adjustably receivable in a tube of a towing vehicle and terminates in an apertured plate inclined to the vertical. A second apertured plate is attachable by bolts to the first plate in any of a plurality of different positions to provide a plurality of different heights relative to the shank of a towing ball supported from the second plate. The shank and plates are invertible relative to the tube and the towing ball to double the number of heights which the ball may have with respect to the vehicle. The inclination of the plates provides desired clearances for a trailer coupling and allows use of less material without reducing the strength and rigidity of the device.

Abstract: The invention disclosed relates to a new polyurethane composition having improved flame retardance and to a method for preparing same. The present composition is prepared by using a suspending agent and a surfactant. The suspending agent may be either a surfactant or an appropriate polymer, but to control the cellular structure, a surfactant that does not perform as a suspending agent is desirable. The resultant composition may be sprayed through a high pressure spray gun while permitting formation of heavily loaded flame retardant urethane foams which are neither dusty nor lose solids upon washing.

Abstract: The invention provides a kit of parts, and a procedure for welding together such parts, to provide a strong trailer hitch for cars. The components of the hitch are such that they can be welded together in various different configurations so as to fit the large majority of cars, station wagons, pickup trucks and vans manufactured in North America. One feature of the hitch is that the socket member which receives the ball assembly is welded into a central tubular member forming part of a cross member of the hitch, and is weldable within this tubular member in different positions to suit required positioning of the ball member.
