20100308209 | System for Charge-Domain Electron Subtraction in Demodulation Pixels and Method Therefor - A method and system enable the subtraction of charge carrier packages in the low-noise charge domain, which is particularly interesting for the operation of demodulation pixels when high background light signals are present. The method comprises the following steps: demodulation of an optical signal and integration of the photo-generated charge carriers; charge transfer to an external capacitance. The second step means a recombination of electrons and holes in the charge domain and an influencing of the opposite charge carriers on the second plate of the capacitance. This approach allows for low-noise subtraction of charge packages in the charge domain and, at the same time, for creating pixels with much higher fill factors because the capacitances can be optimized for storing just the differential parts, without the DC component. | 12-09-2010 |

20110114821 | 3D CCD-Style Imaging Sensor with Rolling Readout - The presented readout structure provides charge transport based readout of a photosensitive device with a minimum number of transport gates. The structure uses the given charge storage buckets of the photosensitive device, separated by a minimum sized barrier-gate, to transport the charge out of the pixel field. This new readout schema allows for a fast readout speed based on a 2 phase transport chain and increases the pixel's optical fill factor by significantly reducing the transport gate size compared to state-of-the-art pixels using a 3 or 4 phase CCD readout chain. This readout structure can be exploited for standard photo-detecting elements such as e.g. pinned photo-diodes or any enhanced pixel structure that has additional intelligence incorporated as well. Typical applications are 2D- or 3D-imaging. The process used for manufacturing a sensor with such a readout scheme requires preferably charge transport mechanisms like charge-coupled gate devices as well as the possibility of integrating circuitries of high density. The exploitation of such a combination of process-related features results in a new sensor readout technique that allows for optimizing the pixel's dynamic range and optical fill factor. | 05-19-2011 |

20110273561 | Multistage Demodulation Pixel and Method - A demodulation structure for a n-tap pixel, mainly for 3D time-of-flight (TOF) applications uses a 2-stage switch structure for demodulating a modulated electromagnetic wave. An almost arbitrary number of storage sites per pixel can be implemented enabling an almost arbitrary number of samplings captured during one exposure. It also provides the option to demodulate and integrate different phasing samples according to the different modulation frequencies within the same exposure. | 11-10-2011 |

20150105734 | SYRINGE - The invention provides a syringe for use in an ophthalmic injection. The syringe comprises a body, a stopper and a plunger. The body comprises an outlet at an outlet end and the stopper is arranged within the body such that a front surface of the stopper and the body define a variable volume chamber from which a fluid can be expelled though the outlet. The plunger comprises a plunger contact surface at a first end and a rod extends between the plunger contact surface and a rear portion. The plunger contact surface is arranged to contact the stopper but not couple thereto, such that the plunger can be used to force the stopper towards the outlet end of the body, reducing the volume of the variable volume chamber, but not to move the stopper away from the outlet end. | 04-16-2015 |

20090293702 | MUSICAL INSTRUMENT SUPPORT BRACE - A support brace for a musical instrument such as a base trombone has a flexible band which is configured to be wrapped around a user's wrist and hand. The band has an upwardly extending first pocket which contains a first reinforcement member. Straps extend from the band and employ hook and loop fastener material to adjustably retain the band on the user's wrist and hand. An elliptical support knob extends outwardly from the band and is configured to receive and support a horizontal tube portion of the musical instrument. A first fastener with a head extends through the first reinforcement member and the band and is secured to the support knob, thereby joining the knob to the reinforcement member so that forces applied to the support knob are carried to the first reinforcement member. The instrument height can be adjusted by rotating and securing in place the elliptical support knob. | 12-03-2009 |
