Abstract: Abstract of the Disclosure A motorcycle accident simulating test dummy and method utilizing this test dummy as disclosed wherein the test dummy includes motorcycle handle bar gripping means operable to releasably connect the dummy and motorcycle handle bar means.     The motorcycle handle bar gripping means is operable to release the dummy from the motorcycle handle bar means after gripping force, imposed by the motorcycle handle bar gripping means on the handle bar means is overcome by the inertial forces imposed on the dummy during accident simulation.  Sensor means are operable to sense an accident simulating condition imposed on said limb means, with such sensor means being operable to generate data signal means in response to the sensing by the sensor means.  Data receiving and storage means are operable to receive the data signal means from the sensor means and store such data within the body means of the test dummy.  Housing and shock protecting means, housing the data receiving means, are wholly contained within the body means of the test dummy and are operable to shield the data receiving means from forces imposed on the dummy during accident simulation.  Signal transmitting means are provided which are operable to transmit the data signal means from the sensor means to the data receiving and storage means, the signal transmitting means being contained entirely within the dummy and being free of externally extending transmitting means physically attached to any means apart from the test dummy.     The limb means include frangible fracture simulating means operable to fracture in response to inertial stress or external forces imposed on the test dummy during accident simulation. Such frangible, fracture simulating means include visual indicating means operable to provide a visual simulation of limb fracturing, and means operable to permit relative movement between fractured limb means segments, thereby simulating relative freedom of movement of fractured limbs during simulated accidents.

Patent CA-2024433-A1 (CA)
IPC: G11C11/406
Filed: 1990-08-31
Abstract: ABSTRACT OF THE DISCLOSURE    A main memory control system has an initial data generating circuit for generating initial data, an initialization control circuit for activating an initialize signal in response to an initialize command, and a refresh control circuit that generates refresh addresses.  When the initialize signal is inactive, the main memory control system performs normal read, write, and refresh operations.          When the initialize signal is active, the main memory control system selects the initial data by means of a data multiplexer and performs only write operations, writing the initial data at refresh addresses generated by the refresh control circuit.  If the main memory has an interleaved structure, the initial data are written in all leaves simultaneously.
