Publication number: 20240091537Abstract: Provided are systems and methods for treating pain in the head and neck, including headache pain. The systems and methods may be used to deliver electrical stimulation to the occipital nerve(s). The systems and methods may be used relieve pain in the region innervated by the targeted occipital nerves as well as one or more regions of referred pain that occur outside the innervation region of the occipital nerves. Due to the complex structures and anatomy around the occipital nerve(s), precise placement of the lead is achieved by the described systems and methods.Type: ApplicationFiled: October 12, 2023Publication date: March 21, 2024Inventors: Joseph W. Boggs, Nathan D. CROSBY, Amorn WONGSARNPIGOON, Claire ZURN, Matthew G. DEBOCK, Meredith J. McGee, Robert B. STROTHER

Patent number: 6925909Abstract: The present invention is a device for holding a fastener for fastening or unfastening of said fastener. It includes an elongated member having a central portion, the central portion being a handle, and having a first and second end. The elongated member has a central axis. The first end of the elongated member has a first pair of gripping fingers substantially parallel with the central axis, and the second end has a second pair of gripping fingers substantially non-parallel with the central axis. The first pair of gripping fingers and the second pair of gripping fingers each have opposing fingers with non-straight inside opposing surfaces, and include a biasing spring that biases each gripping finger of each pair of gripping fingers toward one another. The first pair of gripping fingers and the second pair of gripping fingers are adapted to removably retain a fastener.Type: GrantFiled: October 8, 2003Date of Patent: August 9, 2005Inventors: Robert J. Crosby, John V. Jaunarajs

Patent number: 5801530Abstract: A proximity sensor includes a transducer and a circuit having a switch that changes state in response to a presence of an object in spaced relation to the transducer. The transducer includes a magnetic form defining a generally planar surface facing a sensing zone of the sensor. The magnetic form includes a side surface that extends away from the sensing zone and an internal cavity that opens outwardly toward the sensing zone. A sensing coil is positioned within the magnetic form cavity. The transducer additionally includes a sensor housing supporting the sensing coil and the magnetic form in relation to the sensing zone. A non-ferrous metal shield is positioned inside the sensor housing to surround at least a portion of the magnetic form and enhance a sensing range of the proximity sensor. The shield has an edge that faces the sensing zone located substantially co-incident with the generally planar surface of the magnetic form.Type: GrantFiled: January 23, 1997Date of Patent: September 1, 1998Assignee: Namco Controls CorporationInventors: Robert J. Crosby, Harold W. Everson, Jr.

Patent number: 5398182Abstract: A power supply wherein the rectified output of two or more transformer secondaries are connected in series and then parallel each half cycle of an alternating current energization signal. Logic circuitry monitors the rectified output and automatically switches from a series to a parallel connection to provide a regulated power supply output.Type: GrantFiled: July 20, 1993Date of Patent: March 14, 1995Assignee: Namco Controls CorporationInventor: Robert J. Crosby

Patent number: 5244583Abstract: A process for dewatering sludge on a flight of a foraminous filter belt that moves in a substantially longitudinal direction between sludge deposit and sludge discharge positions is disclosed herein.Type: GrantFiled: August 10, 1990Date of Patent: September 14, 1993Assignee: Komline-Sanderson Engineering Corp.Inventors: John Goron, Ronald G. Renza, Robert J. Crosby, Erich W. Sodtalbers

Patent number: 4986911Abstract: Apparatus for enhancing dewatering of sludge on a filter belt by the use of conical plows that elevate and mix the sludge. The angles of the plows with the horizontal may be progressively increased, and thereby increase elevation and mixing of the sludge as it moves downstream on the belt toward discharge position.Type: GrantFiled: July 20, 1989Date of Patent: January 22, 1991Assignee: Komline-Sanderson Engineering CorporationInventors: John Goron, Ronald G. Renza, Robert J. Crosby, Erich W. Sodtalbers

Patent number: 4571501Abstract: A three or four-terminal electronic control circuit utilizes a thyristor and a transistor connected in their regenerative circuit or, alternatively, three transistors interconnected in a regenerative circuit. The thyristor is connected to operate in a remote base mode as a low gain PNP transistor, together with a bipolar NPN transistor. The thyristor and transistor are connected in a regenerative circuit which results in very high gain, low input current, with low cost and complete control for ON and OFF, and even intermediate range conditions due to direct access to the base of the NPN transistor. A switch may be connected to the base of the NPN transistor to control the current thereinto, and when current flows into this base, then the transistor and thyristor are connected toward regenerative conduction. When the base current is terminated by the switch, then the circuit degenerates toward non-conduction.Type: GrantFiled: October 12, 1983Date of Patent: February 18, 1986Assignee: Acme-Cleveland CorporationInventor: Robert J. Crosby

Patent number: 4398130Abstract: The present invention relates to a lighting unit having low and high light levels and employing an efficient arc lamp as the source of light during the high level setting. The unit employs a filamentary light source for the production of light during low light level operation, the filament acting as a resistive ballast for the arc lamp during high level operation. Practical embodiments operate in a conventional three-way light socket with the sequences being off, low, high and low, and off, low, high, and high.Type: GrantFiled: March 8, 1982Date of Patent: August 9, 1983Assignee: General Electric CompanyInventors: Robert J. McFadyen, William Peil, John M. Davenport, Robert J. Crosby

Patent number: 4107661Abstract: A device is provided for a meter having an indicator, e.g. a pointer, and which detects the presence or absence of the meter pointer at one or more set points or between two set points. The device does not alter the operation of the meter and may be coupled to an alarm or other signal, or it may be used to actuate a mechanism under control of the meter. The device comprises at least one light-emitting diode which produces radiation which falls on a specific area of the meter face and on the meter pointer (if it is within that area) and is reflected from the meter face (and the pointer) to a phototransistor or other suitable receiver which "reads" the signal produced by the radiation reflected from the meter face and the pointer, if present in the area read. The device is mounted so that it can be moved to any desired area of the meter face. Preferably the device is mounted externally to the meter. However, it may be enclosed within the usual meter housing, without altering the operation of the meter.Type: GrantFiled: August 17, 1976Date of Patent: August 15, 1978Assignee: Horizons Incorporated a division of Horizons Research IncorporatedInventor: Robert J. Crosby

Patent number: 4092164Abstract: A method and apparatus for monitoring the buildup of fog in a non-silver free radical film while a latent image in said film is being optically developed, wherein the buildup of fog is sensed by radiation directed at a non-image area of said film and reflected from said area to a sensing device. The reflected radiation is altered as the buildup of fog takes place.Type: GrantFiled: May 27, 1975Date of Patent: May 30, 1978Assignee: Horizons Incorporated a division of Horizons Research IncorporatedInventor: Robert J. Crosby

Patent number: 3994728Abstract: A method for monitoring the optical development of non-silver free radical film in which the fog buildup in a selected non-image portion of the film is used to control the intensity and/or duration of the development exposure so as to insure a desired level of contrast between image and non-image areas in the developed film.Type: GrantFiled: February 24, 1975Date of Patent: November 30, 1976Assignee: Horizons Incorporated, a division of Horizons Research IncorporatedInventors: Robert J. Crosby, Kenneth F. Karpinski, David R. Schaller
