Abstract: A power line communication system communicates a ballast dimming level to an electronic ballast over an AC power line. A power line controller is operable to generate the ballast control signal and to insert that signal on the AC power signal being transmitted over the AC power line. A power line receiver receives the AC power signal and extracts the ballast control signal from the AC power signal to generate the dimming level signal corresponding with the desired ballast dimming level. To insert the ballast control signal on the AC power signal, the power line controller has a transformer coupled to the signal pattern circuit. The secondary winding of this transformer is connected in series with the AC power line to insert the ballast control signal on the AC power signal. This AC power signal is then transmitted to the electronic ballast. To extract the ballast control signal out of the AC power signal, the power line receiver has a resonant circuit connected in series with the AC power line.

Abstract: A receiver in an impulse wireless communication. The receiver (300) includes a pulse-pair correlator (304) that receives a signal (316) and divides it into two signals for paths. One of the signals is input to signal multiplier (312) while another signal is delayed by a delay unit (310). The signal multiplier (312) multiplies the received signal (316) by a delayed signal (318). An integrator (314) integrates an output signal (322) over a designated period of time. An adding module (306) sums an output signal (324) from the integrator (314). An acquiring module (308) compares an summing-up output (326) from the adding module (306) with a predetermined threshold value to detect the existence of a transmitting-standard preamble.

Abstract: The present invention includes systems, methods and apparatus for continuously, independently and in some cases remotely monitoring the operation of a current interrupter used to test a cathodic protection system, or the cathodic protection system itself, for verification of proper operation. Embodiments of the invention include electronic devices that may be temporarily attached to a current interrupter that is being used to test a cathodic protection system, or directly to the cathodic protection system itself. Embodiments of the invention monitor the activity of an interrupter by sampling the output (voltage and time) to identify the cycle(s) of the interrupter. The invention provides truly independent verification since it does not need to know in advance the sequence or cycle times of the current interrupter being monitored. The information obtained by the invention is output so that it may be provided to a user, displayed, downloaded or stored for future reference.

Abstract: In a multiplied pulse generation device, a detection signal is outputted every time a driven object is driven by a specific amount. An actual cycle indicating a time interval between the detection signal and a previous detection signal is measured.

A multiplied pulse is sequentially generated in such a manner that a multiplied cycle indicating a time interval per which the multiplied pulse is generated is sequentially changed according to an amount of change from the actual cycle to the estimated cycle.

The switch may switch from the second pulse train to the first pulse train and substantially maintain the first edge sharpness of the first pulse train during a low value of both the first and second pulse trains.

More particularly, the specification discloses detection and attempted correction of at least five possible error mechanisms: the missed detection of a pulse that creates an interval greater than maximum; the missed detection of a pulse that results in an interval still within acceptable boundaries; detection of an extra pulse; a pulse shift that results in data in contiguous intervals being affected; and a pulse shift resulting in a single interval data corruption.

Abstract: A system for generating a signal which, in addition to first information representing the rotational speed of a rotating part, contains at least second information. The signal changes over time between a first and a second current level and/or voltage level (high/low). The first information is represented by the time interval between a substantially identical change either between the first to the second level (high/low edge) or a substantially identical change between the second to the first level (low/high edge). On the other hand, the second information is represented by the length of time either of the first or of the second level. No further current levels or voltage levels are used to transmit the additional information, and that the additional information can be evaluated relatively simply. High data integrity can be attained by pulses which are as long as possible.
