Abstract: A shock-absorbing bumper comprises a semi-rigid resilient fascia and a bumper bar spaced rearwardly from the fascia, the space therebetween being filled with an integral skin urethane foam which is resiliently compressible and integrally bonded to the fascia and bumper bar.

Abstract: A shock-absorbing bumper comprises a semi-rigid resilient fascia and a back-up member spaced rearwardly from the fascia, the space therebetween being filled with an integral skin urethane foam which is resiliently compressible and integrally bonded to the bumper members.

Abstract: A vehicle bumper is adapted to provide energy management of impact forces. In a basic embodiment the bumper includes a fascia having a front portion adapted to receive impact forces and upper and lower flanges extending rearwardly from the front portion. A backing member is positioned rearwardly from the fascia and includes means for mounting the bumper on the vehicle. The volume bounded by the backing member and the fascia has a resiliently compressible plastic foam molded in situ and features an integral skin bonded to adjacent surfaces of the fascia and the backing member.

Abstract: A non-random network can connect a common peripheral device to one of a plurality of computers. Each of these computers has a request line for providing a request signal. The network has a plurality of switching devices, each coupled to the common peripheral device and to a corresponding one of the computers. Each of these switching devices is operable in response to a select signal being applied thereto to transfer data between its corresponding one of the computers and the common peripheral device. The network also has a scanner coupled to the plurality of switching devices for operating them in a predetermined order by sequentially applying to them the select signal. This scanner is operable to cease sequencing and to continue applying the select signal to said switching devices to switch a selected one of the computers in response to a persistence of the request signal from the selected one of the computers.
