Patent number: 11058469Abstract: The present invention is generally directed to a reduced shock breakaway screw for use with medical implants and the like having improved solid wall geometry in the breakaway area between the upper and lower portions of the set screw. This improved geometry serves to slow down the fracturing process during shearing, thereby increasing the proportion of energy dissipated as heat from plastic deformation of the material to the amount of energy released as kinetic energy from elastic rebound.Type: GrantFiled: December 15, 2014Date of Patent: July 13, 2021Assignee: The University of AkronInventors: Ajay Mahajan, Jason King, Tim Paul

Patent number: 10045525Abstract: An active non-lethal infrasound system for denying all bird species access to critical areas, particularly in areas around aircraft and other high value systems. The system comprises a plurality of infrasound generators broadcasting continuous infrasonic signals to create a bird-free infrasound active zone within the perimeters of the protected critical area and an infrasound-free dead zones for birds being denied access to the critical areas. Further, an active infrasonic barrier is assembled within an exclusion area surrounding the bird-free infrasound active zone to dampen all low frequency sound waves emanating from the critical area and its perimeters. Wherever the situation allows, a wildlife sanctuary is preferably established further from the exclusion area to attract and protect birds, enforced by broadcasting infrasound signals that simulate natural sounds that attract species typical of the geographic location.Type: GrantFiled: March 4, 2014Date of Patent: August 14, 2018Assignees: TECHNOLOGY INTERNATIONAL INCORPORATED, EMINENT TECHNOLOGY INCORPORATEDInventors: Abdo A.

Patent number: 9907576Abstract: A reduced shock breakaway set screw for use with medical implants and constructs for the spine having improved geometry of the groove area between the upper head portion and lower threaded portion of the set screw. The groove area of the set screw has circular and noncircular portions which in at least one embodiment comprise upper and lower radii separated by a flattened groove bottom. Other embodiments have apertures running between the groove area and an internal cylindrical bore and/or ridges or ribs running across the groove area. The improved geometry serves to slow down the fracturing process during shearing thereby increasing the proportion of energy dissipated as heat from plastic deformation of the material to the amount of energy released as kinetic energy from elastic deformation, thus reducing shock to the patient and physician without changing the preset break-off torque for the set screw.Type: GrantFiled: October 4, 2012Date of Patent: March 6, 2018Assignee: The University of AkronInventors: Ajay Mahajan, Jason King

Patent number: 9851337Abstract: The present invention is directed to a water condition monitoring device and related methods of use that significantly reduce the cost of the water condition monitoring devices by replacing the expensive and bulky multiple sensor electrodes of currently available devices with a single set of two or three metal electrodes to detect and/or measure such water quality parameters as pH, electric conductivity, temperature, and dissolved oxygen content. A microcontroller activates each sensor one at a time in a continuous loop, processing the sensor signals into near real time water condition data, which may be stored, displayed, or sent to a remote location for storage or display.Type: GrantFiled: December 8, 2014Date of Patent: December 26, 2017Assignee: The University of AkronInventors: Kye-Shin Lee, Ajay Mahajan

Patent number: 7914540Abstract: A medical device configured to be inserted into a patient's body to retrieve material from the patient's body includes a basket assembly. The basket assembly is configured to transition between various states including an expanded state and a collapsed state. The basket assembly may be substantially covered in a flexible sheet except for a side-facing opening when the basket assembly is in the expanded state. When the basket assembly is in the collapsed state, the side-facing opening may be substantially closed. The device may be inserted into the patient's body while the basket assembly is in the collapsed state. While in the patient's body, the basket assembly may be transitioned to the expanded state. Then, a physician may maneuver material to be removed from the patient's body into the basket assembly via the side-facing opening. Next, the basket assembly may be transitioned into the collapsed state or a partially collapsed state so that the basket assembly can be removed from the patient's body.Type: GrantFiled: January 10, 2006Date of Patent: March 29, 2011Assignee: Board of Trustees of Southern Illinois UniversityInventors: Bradley F.

Publication number: 20070245406Abstract: The aspects of the present invention provide a computer implemented method, an apparatus, and a computer usable program code for identifying a service processor with current setting information. First stored information for a service processor is retrieved from a first memory in the first service processor. Second stored information for the service processor is retrieved from a second memory in a data processing system to which the service processor is connected. The first stored information is compared with the second stored information to form a comparison as to whether the service processor was previously connected to the data processing system and to determine whether the service processor was a last service processor to fully communicate with system firmware in the data processing system. The service processor has current setting information if the service processor was previously connected to the data processing system and was the last service processor to fully communicate with the system firmware.Type: ApplicationFiled: April 12, 2006Publication date: October 18, 2007Inventors: Gary Anderson, Joseph Armstrong, Brent Jacobs, Ajay Mahajan
