20100271592 | APPARATUS FOR MEASURING CRITICAL FLICKER FUSION FREQUENCY AND METHODS OF USING SAME - Apparatuses and methods are provided for measuring the critical flicker fusion frequency of a subject. The apparatus in one aspect comprises two or more light sources, each flickering at a different predetermined frequency. The subject selects one light source from an array of light sources defining a first range of frequencies, the selection representing the light source of lowest frequency that appears as fused to the subject. The frequencies of the light sources are adjusted to second predetermined frequencies defining a second range. The subject selects the light source of lowest frequency that appears as fused to the subject. The frequency value of the second selection can be assigned as the subject's critical flicker fusion frequency. | 10-28-2010 |
20110125152 | METHODS, SYSTEMS AND DEVICES FOR PERFORMING ELECTROSURGICAL PROCEDURES - Systems, methods, and instruments associated with controlling the operating modes of an electrosurgical instrument using control signals delivered in a wireless manner from the electrosurgical instrument to an electrosurgical generator. The electrosurgical instrument transmits wireless control signals to the electrosurgical generator to initiate delivery of electrosurgical energy. The control signals are delivered to the electrosurgical generator without the need for a conductive cord extending between the electrosurgical generator and the electrosurgical instrument. The energy is delivered to the electrosurgical instrument, in response to the wireless control signals, along a path through an electrode and the physician utilizing the electrosurgical instrument and/or a conductive path external to the physician. The electrode upon which the physician rests provides a path for the electrosurgical energy and optionally prevents burning of the physician during an electrosurgical procedure. | 05-26-2011 |
20110261427 | SYSTEM AND METHOD FOR COLOR MOTION HOLOGRAPHY - A method for producing and replaying a composite color hologram, the method comprising recording a first hologram containing primarily a green content of an intended composite hologram using a substantially collimated recording reference beam, recording a second hologram containing primarily a blue content of the intended composite hologram using a substantially collimated recording reference beam, recording a third hologram containing primarily a red content of the intended composite hologram, transmitting, using a first filter, at least a portion of wavelengths close to Ar at a broad range of angles about an intended viewing angle of the intended composite hologram, blocking, using the first filter, at least a portion of wavelengths close to Ar at angles close to Or, transmitting, using the first filter, at least a portion of wavelengths close to Ab only at angles close to Ob and/or Ag only at angles close to Og | 10-27-2011 |
20130006236 | ELECTROSURGICAL INSTRUMENT WITH ADJUSTABLE UTILITY CONDUIT - An electrosurgical instrument that reduces the amount of fatigue experienced by a physician performing electrosurgery includes a hand piece with a utility conduit connected to the hand piece at a central portion of the hand piece. The utility conduit can include an electrical cable and a smoke/fluid evacuation hose. The hand piece can include a channel system that receives a portion of the utility conduit therein and allows a physician to adjust the location on the hand piece at which the utility conduit exits the hand piece. Adjusting the location on the hand piece at which the utility conduit exits the hand piece can reduce the resistance to the movement of the electrosurgical instrument created by the weight of the utility conduit, which leads to less fatigue in a physician's hand during electrosurgery. | 01-03-2013 |
20130204246 | HAND PIECE WITH ADJUSTABLE UTILITY CONDUIT - An electrosurgical instrument that reduces the amount of fatigue experienced by a physician performing electrosurgery includes a hand piece with a utility conduit connected to the hand piece at a central portion of the hand piece. The utility conduit can include an electrical cable and a smoke/fluid evacuation hose. The hand piece can include a channel system that receives a portion of the utility conduit therein and allows a physician to adjust the location on the hand piece at which the utility conduit exits the hand piece. Adjusting the location on the hand piece at which the utility conduit exits the hand piece can reduce the resistance to the movement of the electrosurgical instrument created by the weight of the utility conduit, which leads to less fatigue in a physician's hand during electrosurgery. | 08-08-2013 |
20140276763 | ELECTROSURGICAL INSTRUMENT - An electrosurgical instrument that reduces the amount of fatigue experienced by a physician performing electrosurgery includes a hand piece with a utility conduit connected to the hand piece. The utility conduit can include an electrical cable and a smoke/fluid evacuation hose. The location at which the utility conduit exits the hand piece is selectively adjustable to reduce the resistance to the movement of the electrosurgical instrument created by the weight of the utility conduit. An electrosurgical instrument may also include an extendable shaft that allows for selective adjustment of the reach of the operational capabilities of the instrument. | 09-18-2014 |
20150182278 | UNIVERSAL SELF-LIMITING ELECTROSURGICAL RETURN ELECTRODE - A self-limiting electrosurgical return electrode for use with electrosurgical procedures is disclosed. The return electrode includes a conductive element and pads disposed on opposing sides of the conductive element. The conductive element, optionally in combination with the pads, is configured to limit the density of electrical current that passes from a patient to the return electrode. The conductive element and the pads can cooperate to define two separate working surfaces on opposing sides of the return electrode. The return electrode can also be safely used with patients of substantially any size and without requiring adjustments to the power settings of an electrosurgical generator. | 07-02-2015 |
