  • Publication number: 20240099556
    Abstract: A computer-implemented method of object enhancement in endoscopy images includes capturing an image of an object within a surgical operative site via an imaging device, determining a size of the object based on the captured image of the object, displaying the captured image of the object, and displaying on the displayed captured image of the object a representation of the determined size of the object.

  • Publication number: 20190137425
    Abstract: A high-gain and low-noise negative feedback control (“feedback control”) system can detect charge transfer in quantum systems at room temperatures. The feedback control system can attenuate dissipative coupling between a quantum system and its thermodynamic environment. The feedback control system can be integrated with standard commercial voltage-impedance measurement system, for example, a potentiostat. In one aspect, the feedback control system includes a plurality of electrodes that are configured to electrically couple to a sample, and a feedback mechanism coupled to a first electrode of the plurality of electrodes. The feedback mechanism is configured to detect a potential associated with the sample via the first electrode. The feedback mechanism provides a feedback signal to the sample via a second electrode of the plurality of electrodes, the feedback signal is configured to provide excitation control of the sample at a third electrode of the plurality of electrode.

  • Publication number: 20080099706
    Abstract: A method is disclosed that includes allowing both frequency and amplitude of a periodic waveform to be adjusted. The method also includes creating the periodic waveform having the frequency and the amplitude. The periodic waveform is coupled to at least one control signal. The at least one control signal is provided to an output suitable for coupling to an actuator of an electronically controlled device. An apparatus and computer program product are disclosed.

  • Publication number: 20060261703
    Abstract: Disclosed is an oscillator that relies on redundancy of similar resonators integrated on chip in order to fulfill the requirement of one single quartz resonator. The immediate benefit of that approach compared to quartz technology is the monolithic integration of the reference signal function, implying smaller devices as well as cost and power savings.

  • Publication number: 20060017523
    Abstract: An electrostatic transducer for micromechanical resonators, in which the electrode gaps are filled with a dielectric material having a much higher permittivity than air. This internal electrostatic transducer has several advantages over both air-gap electrostatic and piezoelectric transduction; including lower motional impedance, compatibility with advanced scaled CMOS device technology, and extended dynamic range. In one aspect, in order to minimize energy losses, the dielectric material has an acoustic velocity which is matched to that of the resonator material. Internal electrostatic transduction can be adapted to excite and detect either vertical modes (perpendicular to the substrate) or lateral modes (in the plane of the substrate). Its increased transduction efficiency is of particular importance for reducing the motional resistance of the latter.

  • Publication number: 20060008661
    Abstract: A method of depositing silicon carbide on a substrate, including placing a substrate in a low pressure chemical vapor deposition chamber; flowing a single source precursor gas containing silicon and carbon into the chamber; maintaining the chamber at a pressure not less than approximately 5 mTorr; and maintaining the substrate temperature less than approximately 900° C. The Method also includes a method for depositing a nitrogen doped silicon carbide by the addition of nitrogen containing gas into the chamber along with flowing a single source precursor gas containing silicon and carbon into the chamber.

  • Publication number: 20050250236
    Abstract: In fabricating a microelectromechanical structure (MEMS), a method of forming a narrow gap in the MEMS includes a) depositing a layer of sacrificial material on the surface of a supporting substrate, b) photoresist masking and at least partially etching the sacrificial material to form at least one blade of sacrificial material, c) depositing a structural layer over the sacrificial layer, and d) removing the sacrificial layer including the blade of the sacrificial material with a narrow gap remaining in the structural layer where the blade of sacrificial material was removed.

  • Publication number: 20050001276
    Abstract: A method of etching silicon carbide using a nonmetallic mask layer. The method includes providing a silicon carbide substrate; forming a non-metallic mask layer by applying a layer of material on the substrate; patterning the mask layer to expose underlying areas of the substrate; and etching the underlying areas of the substrate with a plasma at a first rate, while etching the mask layer at a rate lower than the first rate.
