Abstract: A mechanical coupling for a power steering system (10) and the like having a driven shaft (13) reversibly rotated by a servo-motor (18) in response to either clockwise or counter-clockwise rotation of a drive shaft (12) with the coupling normally connecting the motor (18) to the driven shaft (13). In the event of any failure of the motor (18) to rotate the driven shaft (13) synchronously with the drive shaft (12), as for example due to an electrical power failure, rotation of the drive shaft (12) causes the coupling to disconnect the motor (18) from the driven shaft (13) in the direction opposite to the torque applied by the drive shaft (12) and simultaneously mechanically couple the drive shaft (12) to the driven shaft (13) for direct drive. During that time, the coupling continues to connect the motor (18) to the driven shaft (13) in the direction of shaft rotation. Hence, the direct drive may be assisted by any remaining motor torque, that is, any available torque which is below the level needed to achieve synchronous motion and which is applied in the direction of rotation. But any motor torque or drag applied in a direction opposite to the direction of rotation is disconnected from the driven shaft (13).

Abstract: Une prothèse neurocybernétique pour commander ou prévenir des crises d'épilepsie et d'autres affections motrices comporte un générateur d'impulsions (10) créant des impulsions électriques dont la fréquence se situe entre 30 et 80 cycles par seconde, la durée d'impulsion entre 0,3 et 1 milliseconde et le courant constant entre 1 et 10 milliampères. Le générateur (10) est enfermé dans une coquille d'époxy-titane et est implanté dans le corps, de préférence dans l'aisselle (66). Les lignes d'électrodes (18, 20) partent du générateur (10), passent par un tunnel sous-cutané et arrivent à une connexion d'électrodes (62) sur le nerf vague (26). Des précautions sont prises pour faire varier le signal électrique provenant du générateur (10) après son implantation afin de l'"accorder" au patient. La prothèse peut être conçue de manière à être enclenchée manuellement lorsque le patient ressent l'imminence d'une convulsion. Alternativement, des détecteurs (48, 50) peuvent être prévus pour déterminer des modifications des valeurs des paramètres d'état, comme les ondes électro-encéphalographiques qui précédent une convulsion. Le générateur d'impulsions (10) peut alors être enclenché automatiquement en réponse aux détecteurs (48, 50).

Abstract: A logic system preferably for gallium arsenide integrated circuits uses dynamic pulsed logic gates which switch on each clock pulse, with the logical state of an output or data line being indicated by the phase of the pulsed output, which may be shifted or modulated with respect to a reference. An individual logic gate (1) has a first signal generator having a capacitor (30) which is either charged up or discharged during a set-up phase of a clock cycle, depending upon applied input logic signals. During a second, transmit phase of the clock signal, the signal developed on the capacitor is output from the gate. A second signal generator (112 - 131) is an inverting slave of the first, and outputs the inverse logic state during the succeeding set-up phase of the first generator. 
<??>With each gate switching on every clock period, all switching noise appearing in the ground or power supplies is at or above the clock frequency and can simply be filtered out with small chip capacitors, providing improvements in noise immunity. 
<??>The logic is preferably implemented in gallium arsenide metal oxide semiconductor technology, with the capacitors formed from reverse-biased Schottky diodes and all FET switches capacitively coupled and self biased.
