20120215308 | POWER TRANSFER IN A MEDICAL IMPLANT - A medical implant comprising a power source configured to generate a direct current (DC) signal, a first interface configured to convert the DC signal to an alternating current (AC) signal; and a DC power storage device. The implant also comprises a second interface configured to convert the AC signal received from the first interface via two interface connection lines to a DC signal, and configured to provide the DC signal to the power storage device via two storage connection lines, and wherein the second interface includes: at least one switch disposed between the two module connection lines and the two storage connection lines; and at least one switch controller configured to control the at least one switch to prevent the power storage device from being electrically connected to an opposite polarity of the power source. | 08-23-2012 |
20120226332 | SENSITIVE MEASUREMENTS IN A HEARING PROSTHESIS - Aspects of the present invention are generally directed to taking measurements in a hearing prosthesis. In an embodiment, a power circuit, which may be a switched mode power circuit, is shut down during performance of the measurements to reduce interference. Then, power capacitively stored by the power circuit is used to power the hearing prosthesis during performance of the measurements. In an embodiment, the power circuit increases its voltage just prior to performance of the measurements. This serves to increase the amount of energy capactively stored by the power circuit and thus extends the period of time during which the measurements may be taken while the power circuit is shut off | 09-06-2012 |

20120211448 | PAN AND TILT DRIVE SYSTEM - A pan and tilt drive system for an electrically powered device includes a housing in which an elongated shaft is rotatably supported, which shaft is rotatably driven about a shaft axis by a pan motor. A receptacle is coupled to the shaft and disposed to pivot about a tilt axis which tilt axis is perpendicular to the shaft axis. A tilt subsystem is provided to facilitate tilt motion of the receptacle about the tilt axis. The tilt subsystem includes a tilt motor, a tilt coupling and a tilt rod. The tilt coupling is coupled between the tilt motor and the tilt rod, while the tilt rod is coupled between the tilt coupling and the receptacle. Actuation of the tilt motor effects linear translation of the tilt coupling in a direction parallel to the shaft axis, thereby causing the tilt rod to tilt the receptacle about the tilt axis. | 08-23-2012 |
