Publication number: 20230412050Abstract: A motor system includes a motor having a rotor with a plurality of magnetic poles disposed adjacent a plurality of stator elements. Motion of the rotor is responsive to a change in magnetic flux from the stator elements. A generator comprising one or more coils and/or pickups is configured to generate electromagnetic signals responsive to the motion of the rotor, the change in flux from the stator elements, or both. A controller is configured to generate power from the signals, for operating a processor with memory. The processor and memory are configured to receive the signals, determine a count of cycles and/or direction changes of the motor based on the signals, and store the count in the memory.Type: ApplicationFiled: June 16, 2023Publication date: December 21, 2023Inventors: Tyler Anderson, Steven Besser, Luke Keranen, Bradley D. Schulz, Ryan Bourgoine

Patent number: 9559566Abstract: A motor system comprises a rotor shaft, and a magnetic drive motor and a capacitive drive motor. An engagement system is configured for selectively engaging one or both of the magnetic drive motor and the capacitive drive motor with the rotor shaft, in order to rotate the rotor shaft at a desired rotational speed and generate a desired output torque. An actuator may be coupled to the rotor shaft in order to convert the rotational speed and/or output torque (or a rotational position of the rotor shaft) for operation on a load, for example to position the load rotationally or linearly with respect to the rotor axis, or to exert a force or torque on the load.Type: GrantFiled: June 12, 2015Date of Patent: January 31, 2017Assignee: Tolomatic, Inc.Inventors: Steven DiMarco, Steven Besser, Gary W.

Patent number: 9297865Abstract: Disclosed is a Hall Effect instrument with the capability of compensating for temperature drift consistently, accurately and in real time of operation. The instrument embodies a four-point ohmmeter circuit measuring Hall Effect sensor resistance and tracking the effect of temperature on the Hall Effect sensor. The instrument takes into account a relationship between the temperature and a temperature compensation index on a per probe basis, which has exhibited a deterministic difference observed by the present inventor.Type: GrantFiled: January 21, 2015Date of Patent: March 29, 2016Assignee: OLYMPUS SCIENTIFIC SOLUTIONS AMERICAS INC.Inventors: Andrew Thomas, Steven Besser

Patent number: 8421802Abstract: A peak visualization enhancement system for use with a non-destructive inspection (NDI) instrument using a digital display which replicates the haloing effect of analog cathode ray tube (CRT) displays. A peak detection algorithm is provided which intelligently selects the peak values from within the uncompressed digitized waveform while taking measures to prevent noise spikes and the like from being identified as valid waveform peaks. The digital display then highlights the identified peaks, or a subset of the identified peaks, on the compressed waveform display. In this way the effect of bright spots (halos) about the zero slope points on a waveform displayed on an analog CRT is replicated in a digitally compressed waveform display.Type: GrantFiled: March 6, 2009Date of Patent: April 16, 2013Assignee: Olympus NDTInventors: Andrew R.

Patent number: 7832275Abstract: An ultrasonic inspection system utilizes a tunable digital filter with 4× interpolation. The system is used for scanning objects to be tested and includes a transmit/receive device to generate a test signal and receive an echo signal. A signal processing circuit processes the echo signal with one or more digital to analog converters for converting an analog version of the echo signal to a digital echo signal in the form of streaming digital data which is stored in a memory. The data is stored at a first data rate and read out at the second, slower data rate. An averaging decimator receives and processes the data from the memory and supplies it to an IIR filter and subsequently to an FIR filter and ultimately to a box car filter to effect processing thereon which increases the perceived resolution of the data by a given factor, preferably by a factor of 4.Type: GrantFiled: July 14, 2008Date of Patent: November 16, 2010Assignee: Olympus NDTInventors: Andrew Thomas, Steven Besser, Jason Toomey

Patent number: 7817076Abstract: A multiple mode digitization system for a non-destructive inspection instrument which makes use of a multiplexing circuit and a single set of analog to digital converters to efficiently digitize analog test signals from a plurality of inputs. In the preferred embodiment, each of the analog to digital converters in the system is driven with an independent and separate clock signal, allowing for propagation delay compensation among the plurality of test signals as well as interleaved sampling such that custom sampling rates can be used for each input without the need for more than one clock frequency. In an alternate embodiment, phase adjustments on the sampling clocks are used only for interleave sampling, and digital filters are used to provide signal propagation delay compensation.Type: GrantFiled: August 15, 2008Date of Patent: October 19, 2010Assignee: Olympus NDTInventors: Michael Drummy, Andrew Thomas, Denys Laquerre, David Larochelle, Pierre Langlois, Steven Besser
