Patent number: 9295854Abstract: A light and bioelectric therapy pad that delivers light and bioelectric stimulation to adjacent tissue. The therapy pad includes an electrical tracing circuit containing elongated, parallel and spaced-apart approximate linear tracings (ALT) that provide current flow in opposite directions along the ALT during alternating positive and negative drive cycles of an alternating current (AC) supply. The ALT includes first and second header tracings wired to a row of light emitting diodes (LEDs), with the anodes of a first group of LEDs wired to the first header tracing, and the anodes of the remaining LEDs wired to the second header tracing. The ALTs are wired into the circuit with current flowing to the first header tracing at one end of the row of LEDs, and to the second header tracing at the opposite end, so that adjacent ALT provide current flow in opposite directions during both positive and negative drive cycles.Type: GrantFiled: March 12, 2013Date of Patent: March 29, 2016Assignee: Point Source, Inc.Inventor: Steven H.

Patent number: 6576163Abstract: A method of manufacturing a medical instrument for diffusing light from an optical fiber is provided. The medical instrument includes an optical fiber having a proximal portion including a cladding layer surrounding the core and a distal portion having a diffuser tip comprising a protective coating made of acrylic or methylpentene surrounding the core, an optical coupling layer, and a sleeve. The protective coating strengthens the distal end of the optical fiber so that it can withstand a higher bending moment at failure than the uncladded core. At the same time, the protective layer has an index of refraction that is between the indices of refraction of the core and the optical coupling layer to direct light out of the core through to the optical coupling layer.Type: GrantFiled: October 30, 2001Date of Patent: June 10, 2003Assignee: Indigo Medical, IncorporatedInventor: Steven H.

Patent number: 6225621Abstract: A laser diode (22) emits laser light which is collimated into parallel rays with collimating lens (24). The collimated beams travels as much as 50 meters or more before being reflected back to a photoreceiver (28). A ball lens (26) focuses the reflected light onto the photoreceiver. The photoreceiver, preferably, is a synchronous detector which issues control pulses to a laser drive circuit (42) for causing the laser diode to emit intermittent bursts of laser light. The synchronous detector then compares the timing of received light with the timing of the control pulses to the laser diode to distinguish between true reflected light and stray light. An intensity adjustment (56) adjusts the intensity of the laser light in accordance with a distance between the laser diode/photoreceiver and a reflector. In this manner, distances of 1-70 meters can be accommodated with no lens modification.Type: GrantFiled: May 7, 1999Date of Patent: May 1, 2001Assignee: Automatic Timing & Controls, Inc.Inventors: John D.

Patent number: 6166371Abstract: A Diffuse Reflective Light Curtain System comprises at least one light curtain defining a border of a work zone for a robotic machine. Each light curtain comprises a primary board having multiple wells formed therein. Light emitting diodes (LEDs) and light detectors are alternately placed in the multiple wells. The LEDs shine light up from the wells to form a curtain of light above the primary board. If an object comes into contact with the curtain of light emitted from the LEDs, the light is reflected back to toward the board and enters the wells of the board where the light detectors sense the presence of LED light. When the light detectors in the wells sense the presence of LED light, they send a signal to a controller to indicate that the light curtain has been breached by a foreign object. The controller, in turn, suspends the operation of the robotic machine that is protected by the light curtain.Type: GrantFiled: April 30, 1999Date of Patent: December 26, 2000Assignee: Beckman Coulter, Inc.Inventors: Terry J. Milbrath, Jonn R. Hitch, Joe C. Hlebasko, Steven H. Mersch
