Publication number: 20230064350Abstract: Apparatus and associated methods relate to detection systems with chatter-mitigated output indication. In an illustrative example, a sensor may generate a detection signal as a function of a physical relationship of a target to the sensor. A control circuit may, for example, generate a control signal in response to the detection signal and as a function of a predetermined indication response profile defining a transition threshold for each of multiple nominal transition points. A light-emitting indicator array may, for example, generate spatially distributed indication in response to the control signal. The indication may, for example, change from a first spatial distribution to a second spatial distribution in response to the detection signal crossing a first nominal transition point by at least a corresponding transition threshold (?1i). Various embodiments may, for example, advantageously prevent the visual indication from responding to perturbations in the detection signal.Type: ApplicationFiled: August 30, 2022Publication date: March 2, 2023Applicant: Banner Engineering Corp.Inventors: Chunmei Kang, Amanda Nelson, Brad Ragozzino, William Theunissen, Arthur Padget, Robb Weidemann

Patent number: 11585726Abstract: Apparatus and associated methods relate to a vibrational sensing system (VSS) including an accelerometer and a data processor, which determines an “operational state” of a mechanical drive unit, the processor further employing the “operational state” to gate learning of long-term vibrational data to exclude collection of non-operational data, the long-term data collected to calculate alarm thresholds. For example, vibrations from a target motor are sensed by a coupled accelerometer. Vibrational data from the accelerometer is fed into a data processor which determines the operational state of the motor. The operational state (e.g., on/off indication) may gate data collection such that data is only acquired during on-time, which may advantageously create accurate baselines from which alarm thresholds may be generated, and nuisance alarms may be avoided.Type: GrantFiled: April 9, 2021Date of Patent: February 21, 2023Assignee: BANNER ENGINEERING CORPInventors: Robert T.

Publication number: 20230052882Abstract: Apparatus and associated methods relate to an alignment system including an alignment source module (ASM) and an alignment indicator module (AIM) configured to be releasably coupled to a first unit and a second unit, respectively, of a pair of optoelectronic arrays. In an illustrative example, the ASM may be oriented, when coupled, to emit an optical beam in substantial alignment with a first optical axis of the first unit. The AIM may, for example, be configured, when coupled, to provide a visible indication when the optical beam is within a predetermined near-alignment orientation range relative to a second optical axis of the second unit. Each of the AIM and the ASM may, for example, be configured to axially couple along respective longitudinal axes of the first unit and the second. Various embodiments may advantageously facilitate manipulation of the pair of optoelectronic arrays into near alignment with each other.Type: ApplicationFiled: July 15, 2022Publication date: February 16, 2023Applicant: Banner Engineering Corp.Inventors: Matthew Michael Gelineau, John Klesk

Patent number: 11521328Abstract: Apparatus and associated methods relate to a method of non-contact motion detection. A one-dimensional optical sensor detects motion of a target or objects on a conveyor belt through a continuous measurement of targets or objects and a real-time comparison of the pixel images captured by the one-dimensional optical sensor. In an illustrative embodiment, a one-dimensional sensor may be configured to determine motion of objects based on changes to the captured intensities of pixel images over time. The sensor may continually capture photoelectric pixel images and compare a current pixel image with a previous pixel image to determine a frame differential image value. The frame differential image value is evaluated against a predetermined threshold over a predetermined time period. Based on the evaluation, a signal is output indicating whether the objects on the conveyor belt are moving or jammed.Type: GrantFiled: October 15, 2020Date of Patent: December 6, 2022Assignee: BANNER ENGINEERING CORPInventors: Wade Oberpriller, Paul D.

Publication number: 20220291382Abstract: Apparatus and associated methods relate to detecting jams when an intensity of a reflected signal exceeds a predetermined intensity threshold and an intensity window metric based on historic intensity value(s) fails to exceed an intensity window threshold for more than a predetermined time threshold. In an illustrative example, a jam detection unit (JDU) may emit a signal and detect a reflection of the signal. The JDU may, for example, compare intensity of the reflected signal to the intensity threshold. The JDU, for example, may compare the intensity threshold with at least one historic intensity value to determine the intensity window metric. If the intensity value exceeds the intensity threshold and the intensity window metric has not exceeded the intensity window threshold for longer than the time threshold, then the JDU may, for example, generate a jam signal. Various embodiments may advantageously detect jams based on intensity of a reflected signal.Type: ApplicationFiled: March 8, 2022Publication date: September 15, 2022Applicant: Banner Engineering Corp.Inventors: Wade Oberpriller, Kathryn Grant Phillips Longley

Publication number: 20220291384Abstract: Apparatus and associated methods relate to a field-adjustable distance sensor configured to translate a transfer function of the sensor by a substantially constant value in a position domain by calibration at one or more known distances. In an illustrative example, the transfer function may correlate multiple distances to corresponding position vectors describing a position of a light signal on a receiver. The receiver may, for example, generate a detection signal corresponding to a position on the receiver of a light signal reflected off a target. A control circuit may, for example, generate a position vector in response to the detection signal. A calibration constant (C) may be generated, for example, as a function of a known distance of the target and position vector. C may be applied, for example, to translate the transfer function in the position domain. Various embodiments may advantageously reduce non-linear error in a distance sensor.Type: ApplicationFiled: May 19, 2021Publication date: September 15, 2022Applicant: Banner Engineering Corp.Inventor: Wade Oberpriller

Publication number: 20220229180Abstract: Apparatus and associated methods relate to an array of individually readable distance sensors disposed along a first axis on a platform and configurable to detect penetration of a first plane containing the first axis, and an array of individually controllable light emitting indicators disposed on the platform along at least a second axis and configurable to emit visual indicia to a user out of the first plane. The visual indicia may, for example, be associated with the detected penetration. A reconfigurable predetermined detection window may, for example, be generated by associating adjacent sensors detecting input during a teaching operation. The detection window may, for example, be further generated by determining at least one distance threshold profile as a function of input received from the adjacent sensors during the teaching operation. Various embodiments may advantageously enable efficient configuration of generic sensing and indication units.Type: ApplicationFiled: January 20, 2021Publication date: July 21, 2022Applicant: Banner Engineering Corp.Inventor: Charles Dolezalek

Publication number: 20220137255Abstract: Apparatus and associated methods relate to pairing a receiver with an emitter based on a presence of an amplitude of a spectral profile at at least one predetermined frequency. In an illustrative example, a receiver may receive, from the emitter, an emitted optical signal modulated by the at least one predetermined frequency.

Publication number: 20220065693Abstract: Apparatus and associated methods relate to an open-loop control circuit (OLCC) configured to determine a photodiode element (PDE) drive voltage as a function of a commanded photodiode gain level and a measured temperature signal.
