| 20090140900 | SENSOR INTERFACE DEVICES AND AMPLIFIERS - Disclosed are a sensor interface device and an amplifier used in a sensor system. The sensor interface device in one implementation has a first chopper configured to shift input signals of the sensor system from a baseband frequency to a first frequency, an instrumentation amplifier configured to amplify the shifted signals, a bandpass Delta-Sigma modulator configured to digitize the amplified signals, and a second chopper configured to shift the digitized signals from the a first frequency back to the baseband frequency. The instrumentation amplifier removes the DC offset generated from the first chopper and therefore all sources of DC offset are eliminated in this interface device without bandwidth limitation. | 06-04-2009 |

| 20100190532 | DYNAMICALLY PROVISIONING A DEVICE WITH AUDIO PROCESSING CAPABILITY - An executable is downloaded to an audio output device over a communications link. The executable may configure the audio output device to decode audio encoded in a specified format. The executable may also or alternatively include other audio processing software. The audio may include voice and/or audio playback, e.g., music playback. The ability to download an audio executable allows dynamic provisioning of various decoding and/or audio process capabilities to an audio output device. This may eliminate the need to transcode digitized audio for playback at the audio output device, and may also allow the audio output device to decode multiple audio formats without having multiple audio decoders permanently residing within the audio output device. | 07-29-2010 |

| 20080239974 | Measurement of Network Performance in Transporting Packet Streams - A method and apparatus for measuring network performance. A packet from a stream of multimedia data packets is received from across a network during a measurement interval. The time interval from the start of the measurement interval to receiving the packet is measured. The response of a buffer to the received packet is determined. The level of the buffer just before the packet arrives is calculated, based on the time interval. The level of the buffer just after the packet arrives is calculated, based on the previous level. A performance measure for the network is determined based on at least one of the two levels. | 10-02-2008 |

| 20090081304 | Composite pigment nanoparticles and processes to form organic-inorganic nanoparticle composite particles - Milling approaches provide for the efficient formation of composite particles having an inorganic nanoparticle core with an organic coating composition. The nanoparticles can additionally function as a milling media or distinct milling particles can be used and later separated from the product composite particles. In general, the milling is performed in the presence of a dispersing agent that facilitates dispersing of the composite particles in a carrier liquid. The processes described herein can be effectively used in the formation of composite particles comprising organic pigments. Similarly, the composite particles can be formed with other organic compounds, such as organic pharmaceutical compositions. | 03-26-2009 |

| 20110214282 | ACTUATOR FOR MAINTAINING ALIGNMENT OF DIE DETACHMENT TOOLS - A die detachment apparatus for detaching a die from an adhesive tape on which the die is mounted includes a pick-and-place tool movable along a pick-up axis for picking up the die from the adhesive tape and a die ejector comprising an ejector shaft including an ejector pin. The ejector pin is movable parallel to the pick-up axis to raise the die from the adhesive tape to facilitate pick-up of the die by the pick-and-place tool. At least one movable table to which the ejector shaft is operatively coupled is actuable by at least one piezoelectric actuator which is connected to the movable table via a flexure. Actuation by the piezoelectric actuator forces the movable table and ejector shaft to move in directions which are perpendicular to the pick-up axis for alignment of the ejector pin with the die pick-up tool along the pick-up axis. | 09-08-2011 |

| 20090211709 | BONDHEAD ALIGNMENT TOOL FOR A BONDING APPARATUS - An alignment tool for a bonding apparatus comprises a loading surface for receiving a pushing force from a surface of a device which is attached to the bonding apparatus, the loading surface being arranged and constructed to experience a tilting moment upon receiving an unequally distributed pushing force from a misaligned device acting on it. The loading surface transmits the tilting moment experienced by it to a sensing surface which is operatively connected to the loading surface through a columnar body, which has a smaller width than the loading surface and the sensing surface, and which connects the loading surface and the sensing surface. An array of piezoelectric elements communicates with the sensing surface and produces electrical signals in response to the tilting moment such that a computing unit operatively connected to the piezoelectric elements may detect a direction of tilt of the loading surface from the electrical signals produced by the piezoelectric elements. | 08-27-2009 |
