Publication number: 20190143370Abstract: Methods of mitigating current overload of an ultrasonic system having an ultrasonic stack under load at startup are provided. The methods include beginning an ultrasonic cycle in the ultrasonic system having the ultrasonic stack that runs a closed loop phase control through the weld cycle by ramping up the power of the ultrasonic stack under load. During ramping up of the power of the ultrasonic stack under load, a controller lowers the phase to a negative phase. After ramping up the power of the ultrasonic stack under load is complete, the controller raises the phase to 0 degrees and the ultrasonic stack is operating at steady state and with the phase at 0 degrees.Type: ApplicationFiled: October 15, 2018Publication date: May 16, 2019Applicant: Branson Ultrasonics CorporationInventor: Scott CALDWELL

Publication number: 20190118295Abstract: Sensors incorporated within a laser bank detect light emitted by light sources that is directed into and travels through a delivery end of an associated laser delivery optical fiber. The light sources may be positioned between downstream of the delivery end of the associated laser delivery optical fiber and a lower tooling. In some embodiments, the light source is incorporated within a waveguide. In other embodiments, the light source is positioned within a dummy part.Type: ApplicationFiled: September 28, 2018Publication date: April 25, 2019Applicant: Branson Ultrasonics CorporationInventors: Scott CALDWELL, Christopher ALMONTE

Publication number: 20190118288Abstract: Sensors comprising optical sensor fibers detect a laser light output from at least a laser delivery optical fiber to provide feedback of the laser light intensity detected by the optical sensor fiber. The optical sensor fibers may be integrated within a laser delivery bundle, or may be positioned between a delivery end of the laser delivery optical fiber and a plurality of work pieces to be welded. In various aspects, the feedback provided from the optical sensor fibers is used to control the laser light intensity or to alert an operator that the laser light intensity has fallen below a predetermined parameter.Type: ApplicationFiled: September 28, 2018Publication date: April 25, 2019Applicant: Branson Ultrasonics CorporationInventor: Scott CALDWELL

Publication number: 20180290236Abstract: Plastic parts are welded in a laser welding system. An infrared laser source in a laser chamber is controlled by a controller using closed-loop feedback control with a corrected feedback signal that is compensated for background infrared radiation in the laser chamber. Prior to the infrared laser source being turned on, the controller senses with the optical sensor an intensity of background infrared radiation in the laser chamber. Once the laser is on, the controller senses with the optical sensor an intensity of infrared laser radiation in the laser chamber. The controller calculates the corrected feedback signal by subtracting the intensity of the background infrared radiation sensed when the infrared laser source was off from the intensity of the infrared laser radiation sensed when the infrared laser source is on.Type: ApplicationFiled: March 2, 2018Publication date: October 11, 2018Applicant: Branson Ultrasonics CorporationInventor: Scott CALDWELL

Publication number: 20180141157Abstract: A baffled optical waveguide has a body shaped to partially or wholly surround a part or parts being processed by being illuminated with light. The body has optical baffles therein that define light channels through which the light travels as it transits the baffled optical waveguide. Outlets of the light channels are adjacent an opening in the body which receives an area or areas of the parts or parts being processed. Each light channel homogenizes the light as it transits through that light channel. The optical baffles that define the light channels keep light from diverging in the baffled optical waveguide as it transits through the light channels. In an aspect, a part (or parts) is processed by illuminating it with light via the baffled optical waveguide.Type: ApplicationFiled: November 15, 2017Publication date: May 24, 2018Applicant: Branson Ultrasonics CorporationInventors: Hugh T. MCNAIR, Scott CALDWELL, Marian BLASKO

Publication number: 20180120148Abstract: A broken piezoelectric material in an ultrasonic transducer of an ultrasonic stack of an ultrasonic device is detected by measuring a test piezo coupling constant with a test scan of the ultrasonic stack. The test piezo coupling constant is compared to a previously measured baseline piezo coupling constant. The piezoelectric material is determined to be broken when the test piezo coupling constant is less than the baseline piezo coupling constant by more than a predetermined amount.Type: ApplicationFiled: September 11, 2017Publication date: May 3, 2018Applicant: Branson Ultrasonics CorporationInventor: Scott CALDWELL

Publication number: 20140245916Abstract: Systems and methods presented herein provide for igniting or disabling explosive devices through the generation of strong electrical fields and/or the discharge of electrical energy. In one embodiment, a remotely controlled vehicle is provided to remotely detonate or disable improvised explosive devices. The vehicle may contain a high-voltage power supply powering a Tesla coil. The secondary coil of the Tesla coil is attached to an electrode that is swept across an area where an explosive device may be present. The strong electric field around the electrode may induce current within an explosive device or wires connected thereto resulting in the explosive device being ignited or disabled. Discharges from the electrode may directly ignite explosive material or disable detonation control circuitry. The electrode may be located distal to the vehicle and the vehicle itself may be hardened to enhance survivability in the event of an explosion in proximity to the electrode.Type: ApplicationFiled: May 6, 2011Publication date: September 4, 2014Inventors: Richard J. Adler, Vernon Michael Weeks, Michael Knight Wiley, Clinton Scott Caldwell

Patent number: 8100161Abstract: Unabsorbed infrared laser light that has passed though plastic parts to be welded with a low absorption TTIr process is recirculated back to the low absorption weld interface for reabsorption in the process. A beam of infrared laser light is directed at the plastic parts to be welded, a transmissive first part and an absorptive (or partially absorptive) second part. The infrared laser light impinges the transmissive part and first transits through the transmissive part to be welded to a weld interface at the junction of the two parts. At the weld interface, either the infrared laser light is partially absorbed by an additive infrared absorber, the infrared laser light is partially absorbed by the absorptive part, or both. The portion of the infrared laser light that is not absorbed continues through the absorptive part and exits the far side. This infrared laser light is then redirected back to the weld interface.Type: GrantFiled: May 5, 2008Date of Patent: January 24, 2012Assignee: Branson Ultrasonics CorporationInventors: Scott Caldwell, Paul Rooney
