Title: Ultrasound imaging system using beamforming techniques for phase coherence grating lobe suppression
Inventor: BROWN JEREMY
IPC: G01S15/89
Filed: 2011-02-08
Abstract: High-frequency ultrasound imaging can be performed with greater quality and suppressed grating lobes by using methods and systems for effectively reducing the temporal length of transmit grating lobe signals in received ultrasound echoes. Systems and methods are provided for improved high-frequency ultrasound imaging. In various aspects, the method of shortening the time domain of grating lobe signals comprises splitting an array of N transmit elements into K sub-apertures. In further aspects, the grating lobes are suppressed by performing signal processing of the shortened grating lobe signals. In certain aspects, the signal processing method comprises weighting the samples by a calculated phase coherence factor.

Abstract: A combined fracturing and perforating method and device for oil and gas well are disclosed. The method and device can fracture deeply a formation while perforating. The method utilizes an explosion of perforating charge (5) in a combined fracturing perforator to ignite primary gunpowder in the perforator, and burning of the primary gunpowder ignites secondary gunpowder in the perforator; the time difference between a pressure peak of the primary gunpowder and a pressure peak of the secondary gunpowder is 5-10 milliseconds, thus forming an energy complementation, and forming a continuous high-pressure state in the hole, and extending the length of crack. The primary gunpowder is mainly composed of ammonium perchlorate and hydroxyl terminated polybutadiene, and the secondary gunpowder is mainly composed of ammonium perchlorate and polyether. The gun body of perforating gun in the combined fracturing and perforating device is provide with a pressure releasing hole (8) which is directly facing the jet direction of perforating charge; a sealing sheet (9) is arranged on the pressure releasing hole (8). An inner gunpowder box (6) and an outer gunpowder box (7) are installed on the cylindrical charge frame (4), wherein the inner gunpowder box (6) which contains the primary gunpowder is mounted in the cylindrical charge frame (4), and is located between the adjacent shaped-charge perforating charges, and the outer gunpowder box which contains the secondary gunpowder is attached to the outer wall of the cylindrical charge frame (4).

Title: Dynamically enabling guest device supporting network-based media sharing protocol to share media content over computer network with subset of media devices connected thereto
Inventor: WARRICK PETER S
IPC: H04L12/18
Filed: 2012-10-18
Abstract: A media system includes a computer network, a plurality of media devices coupled to the computer network, and a system controller coupled to the computer network. The computer network allows a guest device supporting a network-based media sharing protocol to be coupled thereto. The computer network by default prevents the guest device from utilizing the network-based media sharing protocol to share media content with the media devices. The system controller selects a subset of the media devices for which media sharing is to be enabled for the guest device, the subset including at least one of the media devices but not all of the media devices. The system controller dynamically reconfigures components of the computer network in response to an event occurrence to enable the guest device to utilize the network-based media sharing protocol to share media over the computer network with only the subset of the media devices.

A motor drives a rotor assembly, including at least two main propeller blades, located in the waist portion in one direction for imparting vertical aerodynamic lift to the figurine.  Rotation of the waist portion in one direction causes the hip portion to counter-rotate in the opposite direction due to rotational torque. Center shaft is not connected to the waist portion or the hip portion and therefore rotation of the upper body portion and lower body portion remains independent of the rotation of the waist portion and the hip portion to provide a source of amazement to a user.

Abstract: Cognitive topology is a business methodology enhancing managerial effectiveness and organizational sustainability. It is a system of cognitive indicators, which enables an organization to form managerial goals, initiate strategic changes and optimize managerial/organizational performance.  This is achieved by determining the level of compatibility between the activities going in three main managerial perspectives - human relations, work environment and managerial processes, on the one hand, and the particulars of the business situation, on the other hand. Behavioral traits and characteristics (see p. 4, section II and p. 5 section III) are assigned a key place in creating Cognitive topology. They are the methodological nucleus, which enables the formation of managerial competencies and approaches that lead to optimal behavior and sustainable outcomes in business.
