摘要： A substrate is electromagnetically coupled into an inductance-capacitance resonant circuit formed from (i) a member comprising a ferromagnetic material, (ii) an inductor and (iii) the substrate. The substrate is illuminated for a first time period X to cause photoconduction in the substrate. Decay in conductivity of the substrate is monitored for a second time period Y. The ratio of X to Y is greater than 1:10. Bulk lifetime of the substrate is determined from the decay.

摘要： An apparatus includes a member including a ferromagnetic material, an inductance-capacitance resonant circuit, a substrate disposed relative to the member, and a plurality of radiation sources. The member includes a post disposed at its center and a surface extending to an outer wall. The member defines a gap between the post and the outer wall. The inductance-capacitance resonant circuit is configured to resonate at a measurement frequency. The circuit includes an inductor disposed relative to the post. The substrate is disposed relative to the member. The substrate is electromagnetically coupled to the inductor. The plurality of radiation sources is disposed radially outward from and circumferentially around the post of the member. The apparatus can be used to simultaneously measure conductance (inverse sheet resistance), steady state photoconductance, true steady state minority carrier lifetime, photoconductance build-up and photoconductance decay lifetime.

摘要： A method and system of measuring the differential time of flight of a signal transmitted between first and second transducers. First, multiple broadband signal pulses are transmitted in a first direction by the first transducer and received by the second transducer. Then, the received pulses are averaged to form a first received waveform. Next, multiple identical pulses are transmitted in a second direction and the received pulses are again averaged to form a second received waveform. Then, the first and second waveforms are cross-correlated. The peak of the cross-correlation data identifies a coarse measurement of the differential time of flight of the signal. Also, multiple sinusoidal signal pulses are transmitted in each direction and averaged, thereby creating third and fourth received waveforms. A first point is selected on the third waveform and first phase information is generated from a Fourier transform of the center frequency vector beginning at the first point. Then, a second point on the fourth waveform is determined by summing the first point and the coarse measurement. Second phase information is generated from a Fourier transform of the center frequency vector beginning at the second point. The second phase information is subtracted from the first phase information, and the difference is converted into a time value. That time value is added with the coarse measurement, thereby producing a precise differential time of flight measurement.

摘要： A remote control system having a universal transmitter capable of being programmed to match the frequency and modulation pattern of any pulse modulated remote control transmitter. The system combines the universal transmitter and a separate apparatus for programming the universal transmitter. The programming unit detects the frequency and modulation pattern transmitted by a selected transmitter. The programming unit transfers the detected modulation pattern to the universal transmitter. The universal transmitter is operative to transmit the frequency detected by the programming unit. The universal transmitter thus duplicates the transmission of the selected transmitter. The system, apparatus and methods of this invention are particularly well adapted for application to low cost remote control transmitters permanently installed in vehicles.

摘要： A method and apparatus for causing a plurality of navigational lanterns, each equipped with an independent light sensing device and connected to a common synchronizing terminal, to actuate simultaneously at dusk, and deactuate simultaneously at dawn. The light sensing device senses the three levels of day, twilight and night. When a sensing device senses day, the connected lantern is disabled from flashing and is disabled from sending a synchronizing signal to other lanterns to flash. When a sensing device senses twilight, the connected lantern is enabled to receive the synchronizing signal, but is disabled from sending a synchronizing signal. When the sensing device senses night, the connecting lantern is enabled and a synchronizing signal to flash is sent to all of the lanterns.
