Patent number: 11986787Abstract: A method for enhancing mixing and aeration of a liquid reaction medium in a toroidal bioreactor vessel includes dispensing a liquid reaction medium into an interior of a toroidal bioreactor vessel, the interior being bounded by an inner surface, a textured surface being arranged on at least a portion of the inner surface, the textured surface having a plurality of upstanding protuberances. The toroidal bioreactor vessel is rotated in an orbital motion such that there is a resonant frequency traveling wave of the fluid orbiting in one direction in the interior of the toroidal bioreactor vessel when a particular orbital speed is imparted to the toroidal bioreactor vessel.Type: GrantFiled: September 28, 2020Date of Patent: May 21, 2024Assignee: Finesse Solutions, Inc.Inventors: Mark D. Selker, Barbara Paldus

Patent number: 11886176Abstract: A process and/or a bioreactor control system for controlling a bioreactor. The bioreactor control system includes a bioreactor, a sensor, an electronic card, and a bioreactor controller. The sensor is proximate to the bioreactor and configured to generate a signal indicative of an operating condition of the bioreactor. The signal is then transmitted to the electronic card. Receiving the signal, the electronic card processes the signal to generate a converted signal. The converted signal is then transmitted to the bioreactor controller. The bioreactor controller, in turn, processes the converted signal and generates a control signal to modify the operating condition of the bioreactor.Type: GrantFiled: March 16, 2021Date of Patent: January 30, 2024Assignee: Finesse Solutions, Inc.Inventors: Mark D. Selker, Barbara Alice Paldus

Patent number: 10185314Abstract: The present set of embodiments relate to an environmental condition monitoring and control system employing a software based virtual transmitter for a bioreactor or mixer. The system includes a probe for measuring a condition in a bioreactor that can generate a signal. Measured conditions may include pH, DO, temperature, and pressure. The signal can travel to an electronic card capable of converting the signal from analog to digital and the card can then send the converted signal to a digital controller. The condition monitoring and control system eliminates hardware redundancies and increases versatility by then displaying the converted signal in a software-based virtual transmitter on a non-dedicated human machine interface.Type: GrantFiled: January 31, 2018Date of Patent: January 22, 2019Assignee: Finesse Solutions, Inc.Inventors: Mark D. Selker, Barbara Alice Paldus

Patent number: 6273885Abstract: A laser tissue treatment device capable of being handheld, the device comprising a semiconductor diode or diode array laser which emits energy and a device for surface cooling of tissue such that the energy is directed through said cooling device in contact with tissue. The diode laser operates at wavelengths between about 630 nm and 980 nm, and delivers a predetermined amount of energy in a predetermined period of time and having a predetermined spot size. The device utilizes one or more microlenses or microlens arrays to collimate the diode laser energy. Optionally, the device utilizes a deflecting optic for deflecting the diode laser energy through the cooling device which is in contact with tissue in which the deflecting optic is visually transparent such that the operator can see the tissue treatment area. A cooling device such as a sapphire plate or other active or passive cooling means is used to cool the tissue.Type: GrantFiled: August 16, 1998Date of Patent: August 14, 2001Assignee: CoolTouch CorporationInventors: Dale E. Koop, Mark D. Selker, Timothy J. Johnston

Patent number: 5485482Abstract: An efficient, fundamental transverse mode selected, diode pumped, solid state laser is disclosed. The laser consists of a slab of laser gain material such as Nd:YLF. Cavity forming optics are positioned around the slab of laser gain material. A laser diode bar, collimated by a micro-lens is used for side pumping a constrained gain region in the slab of laser gain material, with the dimensions transverse to the direction of beam propagation of the constrained gain region being smaller in at least one axis than the transverse dimensions of the fundamental transverse mode volume in the laser gain material. The cavity forming optics and the side pumping of the constrained gain region act in conjunction such that the fundamental transverse mode is automatically selected in the solid state laser.Type: GrantFiled: December 8, 1993Date of Patent: January 16, 1996Inventors: Mark D. Selker, Robert S. Afzal
