| A computer according to the present invention comprises a mother board (200) upon which is mounted, among other components, a millimetre wave oscillator (201) and a central processing unit (CPU) (202). The millimetre wave oscillator (201) is operable to generate a clock signal and transmit this to the CPU (202) via a link (203). The clock signal may be employed as a system clock signal and a processing clock signal for the CPU (202). Advantageously, the millimetre wave oscillator (201) allows higher frequency clock signals than are currently available in the prior art whilst generating significantly less heat. Therefore, the CPU (202) may not require any cooling system and if it does then a smaller cooling system than is required by the prior art will suffice. Furthermore, the CPU (202) will be more stable than in arrangements. This arrangement requires less power than prior art arrangements and therefore may increase the battery life of a computer according to the present invention. | ||||||

| 13 | System and method for controlling redundant actuators with different dynamics | US15447448 | 2017-03-02 | US10324446B2 | 2019-06-18 | Uros Kalabic; Abraham Goldsmith; Stefano Di Cairano |
| A laser processing system includes redundant actuators positioning a laser spot on a workpiece. The system determines a first trajectory of the first actuator minimizing motion of the first actuator that positions the second actuator such that each point of the reference trajectory is within a range of the second actuator and determines a second trajectory of the second actuator based on a difference between the reference trajectory and the first trajectory. For each axis of control, the system determines an envelope centered on the reference trajectory with a width not greater than the range of the second actuator and determines shortest trajectory traversing the envelope along the time domain to produce the first trajectory. Hence, the first trajectory includes a set of straight segments satisfying the constraints defined by the shape of the envelope. The system includes controllers for control the motion of redundant actuators. | ||||||

| 15 | Broadbend pulsed microwave generator having a plurality of optically triggered cathodes | US472198 | 1995-06-07 | US5563555A | 1996-10-08 | Ervin J. Nalos; James C. Axtell |
| Disclosed is a method and apparatus for generating a very fast electron pulse (30) in a vacuum. The electron source comprises a pulse-forming line (12), a solid-state switch (14), a cold field-emitting cathode (16), and an anode grid (18). The anode grid forms a portion of a side of an evacuated circuit (20) that may be used to produce an oscillating output signal or that may be a portion of a waveguide carrying an rf signal to be amplified. In operation, the pulse-forming line is charged to a desirable voltage. The solid-state switch is then closed, coupling the pulse-forming line to the cathode. An electric field develops between the cathode and anode grid. Under the influence of the electric field, the cathode emits an electron current pulse that is attracted by the anode grid. The current pulse enters the region between the anode and closure grids, and interacts with the electromagnetic field in the cavity at the appropriate time to add its energy to the electromagnetic field of the cavity. A group of electron sources can be employed to provide rf generation or wideband amplification in a waveguide circuit through proper timing of the closure of a set of cathode-switch elements configured along the direction of propagation of a wave to be amplified. By proper selection of timing, a very flexible set of output frequencies and waveforms may be obtained. The propagating waveguide circuit may also be made resonant by shorting both ends, and configured for pulse-to-pulse frequency diversity by properly timing the cathode-switch current sources to generate alternative frequencies. The multiple-source resonant circuit can also be used to generate very high peak power pulses by using the set of cathode-switch sources repetitively to build up a high voltage across the cavity, with the output load disconnected, and then to discharge the built-up voltage into the load by closing a switch in the output circuit at the appropriate time. | ||||||
| 16 | Dielectric resonator feed back stabilizer | US632801 | 1990-12-24 | US5103194A | 1992-04-07 | Bernard E. Sigmon |
| A dielectric resonator feed back stabilizer comprising a circulator, 3-dB, 90.degree. hybrid dielectric resonator, and isolator. The circulator provides an input electromagnetic signal from a source to the hybrid, which splits the input signal into two outputs with 90.degree. relative phase difference. One hybrid output is to the load and the other is to a dielectric resonator with high Q. The dielectric resonator reflects a portion of the input signal corresponding to the dielectric resonator operating frequency back to the hybrid which splits the reflected signal into two outputs 90 degree relative phase difference. The first signal reflected back through the hybrid, 180 degrees out of phase with the hybrid input signal from the circulator, is cancelled by superposition with the hybrid input signal. The second reflected signal travels through an isolator to the circulator injection locks the source input signal. | ||||||

| 18 | High peak power microwave generator using light activated switches | US915649 | 1978-06-15 | US4176295A | 1979-11-27 | Michael C. Driver; James G. Oakes; John R. Davis |
| A high peak power microwave generator is disclosed in which a plurality of transmission lines are connected to an output wave guide at predetermined intervals along the direction of propagation. Each transmission line is periodically charged, and this electromagnetic energy is released into the wave guide upon the actuation of a light activated silicon switch (LASS) diode connected to the transmission line. The LASS diodes are actuated simultaneously by a laser beam which traverses equal optical paths to each switch. The coincident switching of the transmission lines enables the power in each line to be additive in the wave guide, and much higher output pulses can be obtained. Further, the high speed switching capabilities afforded by the LASS diodes means that the resulting high power can be obtained at a much higher frequency. | ||||||
