Patent number: 8161972Abstract: A method of operating a ventilator assembly having inhalation and exhalation passages communicating with one another, and a respiration assembly that can perform repetitive respiratory cycles. The method includes (a) repetitively cycling the respiration assembly so that during the inhalation phase, gas in the inhalation passage flows to the patient, and during the exhalation phase, an exhalation valve is maintained relatively closed and the exhaled gases flow pass the vocal cords and out of the mouth thereby facilitating the patient's ability to speak, (c) monitoring the pressure within at least one of the passages during the exhalation phase, and (d) determining whether a circuit disconnect or an occlusion exists based on the pressure monitoring.Type: GrantFiled: August 17, 2007Date of Patent: April 24, 2012Assignee: RIC Investments, LLCInventor: Fernando Isaza

Patent number: 8161974Abstract: An apparatus for providing hearing protection to a wearer includes an incorporated set of eyewear having an eyewear frame. In one version, a pair of ear muffler tubes are coupled to the supporting members of the frame or made integral therewith, the muffler tubes each extending to the entrance of the ear canal of a person to reduce the level of ambient noise in the ear canal and includes at least one muffler tube of appropriate dimensions sufficient to isolate the ear canal from ambient air that substantially reduces the acoustic impedance at the entrance of the ear canal over a wide range of audible sound frequencies. A connecting tube for attachment to the ear canal is coupled to the ear muffler tube.Type: GrantFiled: August 18, 2009Date of Patent: April 24, 2012Assignee: Syracuse UniversityInventors: Gregory D. Post, Jozef J. Zwislocki, Robert J. DiNardo

Patent number: 8161977Abstract: A process and system are disclosed for downloading sensor data, stored in a memory device of a surgical cutting and fastening instrument, to an external or remote computer device. The process may involve storing data from one or more sensors of a surgical cutting and fastening instrument in a memory device of a control unit of the surgical cutting and fastening instrument during a surgical procedure involving the surgical cutting and fastening instrument. Next, after the surgical procedure, a data link between the control unit and the remote computer device is established. Then, the sensor data can be downloaded from the control unit to the remote computer device.Type: GrantFiled: September 23, 2008Date of Patent: April 24, 2012Assignee: Ethicon Endo-Surgery, Inc.Inventors: Frederick E. Shelton, IV, David C. Yates

Patent number: 8161978Abstract: A method for treating the lung during an acute episode of reversible chronic obstructive pulmonary disease such as an asthma attack. The method comprises transferring energy to an airway wall of an airway such that a diameter of the airway is increased. The energy may be transferred to the airway wall prior to, during or after an asthma attack. The energy may be transferred in an amount sufficient to temporarily or permanently increase the diameter of the airway. The method may be performed while the airway is open, closed or partially closed.Type: GrantFiled: March 18, 2010Date of Patent: April 24, 2012Assignee: Asthmatx, Inc.Inventors: Christopher J.

Patent number: 8161980Abstract: A frontal hairpiece for providing a naturally-appearing augmented frontal hairline when applied to the wearer. A frontal foundation has a forward edge, a rearward edge, a first end and a second end. The frontal foundation is thin, flexible and made from a net-like construction which substantially blends with the skin color of the wearer. The forward edge traces a tortuous pathway from approximately the first end to approximately the second end. Embodiments may include an elastic band portion connected to the frontal foundation, with first and second rear strap portions disposed therebetween. Hair is attached to the frontal foundation in a first density pattern which mimics a natural transition of a wearer's forehead into a frontal hairline. The first density pattern of some embodiments may be characterized by a greater density of hair strands applied proximate the rearward edge of the frontal foundation compared to the density of hair strands applied proximate the forward edge.Type: GrantFiled: February 4, 2010Date of Patent: April 24, 2012Inventors: Junichi Inoue, Helene Stahl
