Patent number: 9686623Abstract: A hearing actuator (10) for implantation in the middle ear of a user. The actuator comprises transducer means (for example a piezoelectric device) (12) for converting electrical input signals into mechanical vibrations, and attachment means (16) for attaching one end of the transducer means to a first part of the middle ear. The actuator also comprises contacting means (14) which extends from an opposite end of the transducer means such that a longitudinal axis of the contacting means is substantially parallel to a longitudinal axis of the transducer means. The contacting means is for contacting a second part of the middle ear (to which it may be attached), so as to transmit the mechanical vibrations of the transducer means thereto.Type: GrantFiled: May 12, 2008Date of Patent: June 20, 2017Assignee: Sentient Medical LimitedInventors: Eric William Abel, David Ernest Young, Robin Christopher Brodie

Patent number: 9416894Abstract: A system for verifiably locking a first cylindrical component to a second cylindrical component in a safe and secure manner. The system provides a visible indication when the first component and second component are fully and effectively secured. The first cylindrical component comprises a lock cylinder fixedly attached to the first cylindrical component. The lock cylinder comprises a lock piston. The second cylindrical component comprises a channel with a guide region and a lock region. The visible portion of the lock piston provides an indication of whether or not the lock piston is secured in the lock region of the channel. The system is also capable of being operated from a control panel to operate the locks, receive signals from sensors, and to display the lock status of the system. The system offers redundant verifications to enhance safety in operating environments.Type: GrantFiled: June 25, 2014Date of Patent: August 16, 2016Inventor: Leo William Abel

Patent number: 9004175Abstract: A method and system for rapid containment and intervention of a subsea well blowout that can be performed in a rapid and efficient manner, where containment will minimize the damage to the environment and assets. The method can include disconnecting a riser from a subsea well after a blowout has occurred and moving the mobile offshore drilling unit away from the subsea well. Connecting a lower marine riser package with a blowout preventer, and diverting the well. The pressure and flow of the well fluid can be observed. At least of portion of the diversion path can be closed off and kill fluid and or cement pumped to the subsea well to kill and control the well.Type: GrantFiled: January 24, 2013Date of Patent: April 14, 2015Inventor: Leo William Abel

Patent number: 8920496Abstract: An ossicular replacement prosthesis (ORP) (10) for coupling a first point to a second point in the middle ear of a patient, to replace all or part of the ossicular chain. The ORP includes a coupling having a variable configuration for accounting for pressure differentials. The coupling includes a fluid filled chamber (28, 14) having two relatively moveable portions (12, 22) for varying the configuration of the coupling. The coupling further includes unsealed portion constituting leak portion and flowpath portion for permitting displacement of the fluid (30). The relative movement of the relatively moveable portions is controlled by the movement of the fluid in said chamber. The chamber is configured to restrict the movement of the fluid such that relative movement of the moveable portions is permitted in response to quasi-static changes in pressure, and is substantially prevented in response to vibrational changes corresponding to sound frequencies.Type: GrantFiled: March 3, 2008Date of Patent: December 30, 2014Assignee: Sentient Medical LimitedInventors: Eric William Abel, Frank Abraham

Publication number: 20070140804Abstract: A method of reducing the effective width of cargo, such as a concrete double-tee. The method comprises positioning the arm in a first position in which the arm is substantially horizontal, the arm being pivotally biased toward the first position, lowering the double-tee onto the arm such that the first leg of the double-tee is received by the first bracket and the second leg of the double-tee is received by the second bracket, and pivoting the arm and double-tee to a second position in which the second end of the arm contacts the base to support the arm, the arm being biased toward the second position when the arm supports the double-tee. The concrete double-tee includes a deck, a first leg and a second leg. The support structure includes a base, a stanchion extending upwardly from the base, an arm pivotally connected to the stanchion and extending between a first and second end. The arm includes a first bracket disposed near the first end and a second bracket disposed near the second end.Type: ApplicationFiled: November 28, 2006Publication date: June 21, 2007Applicant: THE CRETEX COMPANIES, INC.Inventors: William Abel, Alan Mackey, John Nanna, Thomas Holmes, Douglas Colclasure
