Patent number: 9156557Abstract: In a first aspect the invention relates to a sensor system (10) for determining a proximity to icing conditions of an environment. The system includes a sensor having a sensor surface (12) for exposure to the environment, an electrically powered heat pump means (16) for cooling and/or heating the surface (12), and a temperature detector (14) for providing a signal representative of the temperature of the surface (12). An environment temperature is determined, and a processor determines, from the temperature detected by the temperature detector (14) and the environment temperature, a proximity to icing conditions of the environment to which the surface (12) is exposed. In a second aspect of the invention the sensor system includes a power monitor for determining an amount of power required to heat or cool the surface through a temperature indicative of ice formation. The processor determines the proximity to icing conditions from the detected temperatures and the amount of cooling or heating power.Type: GrantFiled: December 16, 2009Date of Patent: October 13, 2015Assignee: Penny & Giles Aerospace LimitedInventors: William Penny, Nicholas Kidd

Patent number: 6326777Abstract: A device for sensing velocity variations in a conductive body 10 moving through a magnetic gap 12 between two discrete portions 13, 14 of a magnetic circuit 15. The magnetic circuit 15 generates a magnetic flux 16 in the gap 12 to induce eddy currents 17 in the body 10 moving through the gap. The device includes an eddy current sensor defining at least one further gap 24 through which the body 10 is also moved, and at least one sensor coil 18. A voltage is induced in the coil by variations in the induced eddy currents. The voltage is detectable; providing an indication of variations, that is to say accelerations or decelerations, in velocity by providing two discrete magnetic circuit portions, the size and weight of the device be reduced while enhancing the ability to sense eddy currents. The device may be used in a vehicle to sense vibration, acceleration, or other motion.Type: GrantFiled: June 16, 1998Date of Patent: December 4, 2001Assignee: Penny & Giles International PLCInventor: William A.

Patent number: 6152933Abstract: An intracranial bolt, for installation in an opening in the skull to provide access to the brain for a medical device, has a bore therethrough for the passage of the medical device, and an inflatable member in the bore which when inflated engages a medical device in the bore, releasably anchoring the device. The inflatable member comprises a cylinder of flexible sheet material inside the bore and secured to the wall of the bore defining an annular pocket therebetween. A passage extends through the bolt to the pocket for the introduction of fluid into the pocket to expanding radially inwardly. The bolt in a medical procedure on the brain by forming an opening in the skull; installing the intracranial bolt in the opening in the skull; and securing the cap on the bolt. When it is time to conduct the procedure, the cap is removed and a medical device can be inserted into the brain through the bolt. The inflatable member can be inflated to temporarily hold the medical device in place.Type: GrantFiled: November 10, 1998Date of Patent: November 28, 2000Assignee: Stereotaxis, Inc.Inventors: Peter R.
