| 20090156905 | IMPLANTABLE OPTICAL SENSOR AND METHOD FOR MANUFACTURE - An implantable medical device is manufactured with a hermetically sealed housing and a modular assembly enclosed within the housing. The modular assembly includes a circuit board, an electronic component mounted on a top surface of the circuit board, and a wall formed having an outer surface and an inner surface separated by a top edge and a bottom edge, the wall bottom edge positioned against the circuit board such that the wall encircles the electronic component coupled to the circuit board. The wall top edge is coupled to the housing a ferrule in one embodiment. | 06-18-2009 |
| 20100185262 | CO-LOCATION OF EMITTERS AND DETECTORS AND METHOD OF OPERATION - An implantable medical device having an optical sensor selects the function of modular opto-electronic assemblies included in the optical sensor. Each assembly is provided with at least one light emitting device and at least one light detecting device. A device controller coupled to the optical sensor controls the function of each the assemblies. The controller executes a sensor performance test and selects at least one of the plurality of assemblies to operate as a light emitting assembly in response to a result of the performance test. The controller selects at least one other of the plurality of optical sensor assemblies to operate as a light detecting assembly in response to a result of the performance test | 07-22-2010 |
| 20110190609 | OPTICAL SENSOR FOR MEDICAL DEVICE - An optical sensor for a medical device includes a fixed lens spacing between emit and receive modules to achieve target sensor sensitivity, while varying other sensor parameters in order to increase signal amplitude without increasing power demand. An optical sensor connected to a housing of a medical device includes a circuit board, an opto-electronic component, a wall, a lens, and a ferrule. The circuit board is arranged within the housing. The opto-electronic component is mounted on a surface of the circuit board. The wall protrudes from the surface of the circuit board and surrounds the opto-electronic component. The lens is offset from the surface of the circuit board. The ferrule is connected to the housing, the lens and the wall. An inner surface of the wall mates with an outer surface of the ferrule. | 08-04-2011 |
| 20110190610 | OPTICAL SENSOR FOR MEDICAL DEVICE - An optical sensor for a medical device includes a fixed lens spacing between emit and receive modules to achieve target sensor sensitivity, while varying other sensor parameters in order to increase signal amplitude without increasing power demand. The arrangement of an opto-electronic component within an optical sensor receive module is improved by masking the receive module lens with an opaque member to create a masked lens leading edge that is aligned with a leading edge of the opto-electronic component. | 08-04-2011 |

| 20110190608 | OPTICAL SENSOR FOR MEDICAL DEVICE - An optical sensor for a medical device includes a fixed lens spacing between emit and receive modules to achieve target sensor sensitivity, while varying other sensor parameters in order to increase signal amplitude without increasing power demand. The size of at least one of emit and receive module lenses of an optical sensor, and the offset between the opto-electronic component and the respective lens of at least one of emit and receive modules is decreased to increase amplitude of the signal received by the receive module from the emit module. | 08-04-2011 |

| 20090302896 | SIGNAL CONDITIONING CIRCUIT WITH A SHARED OSCILLATOR - A circuit for signal conditioning including a first stage with a digital/analog converter, a second stage with an I/Q-modulator, and at least one third stage with a mixer. Instead of a multiplicity of independent oscillators, a shared oscillator is provided for the first, second, and third stages, from an output signal of which a respective oscillator signal and clock-pulse signal for each stage of the first, second, and third stages is derived. The oscillator signal and respective clock-pulse signal of the oscillator are supplied via a frequency divider to at least one stage of the first, second, and third stages, or the oscillator signal of the oscillator is supplied via a frequency multiplier to at least one stage. Also, the oscillator signal of the oscillator is supplied as a reference signal to a frequency synthesizer of at least one stage of the first, second, and third stages. | 12-10-2009 |

| 20110062913 | METHOD AND APPARATUS FOR CHARGING A BATTERY - A method and apparatus for identifying different types of energy sources used to charge a battery by receiving energy from at least one of the different types of energy sources at input terminals, identifying the type of energy source, and selecting a mode for charging the battery based on the type of energy source identified. A method and apparatus for protecting against certain energy sources used to charge a battery is also disclosed. | 03-17-2011 |
