  • Patent number: 11918864
    Abstract: Embodiments of putter-type golf club head comprising a striking surface capable of achieving consistent ball speeds across the striking surface to account for various ball impact locations are described herein. The striking surface has at least two materials that differ in concentration away from the geometric center of the striking surface to provide this consistency. Consistent (or uniform) ball speed is achieved throughout the striking surface as the portion of the golf ball that contacts the striking surface interacts with at least two materials having a differing material characteristic.

  • Patent number: 8228903
    Abstract: A system for verifying VoIP call routing information. The system may include an apparatus integrated with a private branch exchange (PBX). The apparatus may store at least one call attribute of a public switched telephone network (PSTN) call initiated to a destination telephone number. The apparatus may verify a destination Voice-over-Internet-Protocol (VoIP) call agent for the destination telephone number based on demonstrated knowledge of the PSTN call. The apparatus may route a new call either over a VoIP network to the destination VoIP call agent or over a circuit switched network based on whether the destination VoIP call agent is verified for the destination telephone number.

  • Patent number: 8087289
    Abstract: A scanning probe system and method for using the same are disclosed. The system includes a probe that interacts with a specimen. The probe is caused to vibrate at a first frequency of the probe. A probe deflection signal indicative of an oscillation amplitude of the probe is generated and used to set the z-position probe position to maintain a property of the probe deflection signal at the first frequency at a predetermined value. A probe signal, having a DC and an AC component is applied between the specimen and the probe. The amplitude of a frequency component of the deflection signal at a mixing frequency of the first frequency and the second frequency is measured and used to generate an image or adjust the DC component.

  • Patent number: 7636349
    Abstract: A method for routing calls in a packet-based network includes receiving a call request at a first call manager from a device that is coupled to the packet-based network. The call request includes a telephone number associated with a plurality of telephony devices that are coupled to the packet-based network and that are controlled by a number of call managers. The method also includes determining a line control process associated with the telephone number that is included in the call request and communicating the call request to the line control process. The method further includes determining a device process controlling each telephony device that is associated with the telephone number included in the call request and communicating the call request from the line control process to the device processes.

    Abstract: Atomic force microscope system is provided which is designed to be incorporated into or attachable to an objective lens which can be mounted on a lens turret of an optical microscope such that simultaneous atomic force microscopy and optical viewing of a sample through the objective lens can be performed. In one embodiment, the atomic force microscope (AFM) is designed to be removably attached to a standard objective lens of an optical microscope. In another embodiment, the AFM system is designed to be removably attached to an optical microscope and includes integrated optics for providing an optical view. In both embodiments, the optics are used solely for generating an optical view and/or other optical contrast mechanisms and are not used in conjunction with a detection mechanism of the AFM.

  • Patent number: 5811821
    Abstract: A single-axis active vibration reducing system for reducing vibrations in an object in a single axis. The vibration isolation system enables the sensing of motion of the center of mass of an object along a single axis and, with the proper positioning of a single sensor-actuator pair with feedback operation, the dampening of vibrations of the object along that axis. Due to the positioning and alignment of the actuator, the vibration isolation system of the present invention does not introduce appreciable off-axis vibration. The vibration reducing system includes an actuator positioned on the object to impart an actuation force along an actuator axis to reduce vibrations of the object in the vibrational axis without imparting substantial motion to the object other than in the vibrational axis.

  • Patent number: 5496999
    Abstract: A scanning probe microscope having numerous advantages is disclosed. Respective scanning force and scanning tunneling probes are removably mounted in the head using kinematic mounting techniques so that they may be substituted for one another without the need to adjust the cantilever deflection sensor. A linear position-sensitive photodetector in the deflection sensor eliminates further the need for adjustments. A motorized, non-stacked x,y coarse movement stage is kinematically positioned with respect to the base and features a minimized mechanical loop to reduce thermal and vibrational effects on the position of the sample. A z coarse movement stage positions the head kinematically with respect to the base and includes a motorized drive means which allows the height, tilt and pitch of the probe to be adjusted. The scanner includes x,y and z sample position detectors which provide an accurate measurement of the position of the sample with respect to the probe.

  • Patent number: 4769593
    Abstract: A method and apparatus for directly measuring steam quality in-line. A variable frequency capacitance cell receives a hybrid stream (one having both liquid and vapor phases). The resultant frequency of the electrical circuit of which the capacitance cell is an element, varies with the dielectric constant of the capacitance cell (i.e., the water vapor concentration in the cell). The resultant frequency of the cell is preferably beat with a reference frequency that is within about 15 MHz from the resultant frequency to facilitate measurement.

  • Patent number: 4610301
    Abstract: A method is provided for modifying an original distribution pattern including an original central injection well and four original corner production wells. One or more new injection wells are provided at locations approximately aligned midway between adjacent ones of the original corner production wells. In addition to the two original corner production wells between which it is located, there are associated with each new injection well four additional new production wells. A first pair of these new production wells is provided at locations substantially aligned between and preferably substantially midway between the original central injection well and the two adjacent ones of the original corner production wells. A second pair of new production wells is located substantially as a mirror image of the first pair about an imaginary straight line between the two adjacent ones of the original corner production wells.
