  • Patent number: RE47637
    Abstract: A smart laser pointer is disclosed in this application that includes a laser coupled to a processor that can disable the laser from operating for a period of time (T) based on a disabling trigger. The smart laser pointer may also include an optical receiver coupled to the processor that detects received laser signals that are emitted from the laser after they are reflected off of a target and a memory storing position information threshold limits. The processor calculates measured position information based on the received laser signals detected by the optical receiver and compares them to the position information threshold limits. A disabling trigger occurs when the position information exceeds the position information threshold limits. The position information and threshold limits may include a distance or a velocity.

  • Patent number: RE48047
    Abstract: A synchrocyclotron comprises includes a resonant circuit that includes electrodes having a gap therebetween across the magnetic field. An oscillating voltage input, having a variable amplitude and frequency determined by a programmable digital waveform generator generates an oscillating electric field across the gap. The synchrocyclotron can include a variable capacitor in circuit with the electrodes to vary the resonant frequency. The synchrocyclotron can further include an injection electrode and an extraction electrode having voltages controlled by the programmable digital waveform generator. The synchrocyclotron can further include a beam monitor. The synchrocyclotron can detect resonant conditions in the resonant circuit by measuring the voltage and or and/or current in the resonant circuit, driven by the input voltage, and adjust the capacitance of the variable capacitor or the frequency of the input voltage to maintain the resonant conditions.
