Abstract: An example method includes determining a point cloud representation of surfaces within an environment. The method further includes providing for display of a graphical interface that shows a model of the surfaces within the environment based on the point cloud representation. The method additionally includes receiving input data indicating one or more positions for one or more virtual sensors on the graphical interface corresponding to one or more physical positions within the environment. The method also includes determining one or more occluded regions within the environment, where the one or more occluded regions are predicted to be occluded from view by one or more sensors positioned at the one or more physical positions within the environment. The method also includes providing for display in the graphical interface of a graphical representation of the one or more occluded regions within the model of the surfaces within the environment.

Abstract: Implementations disclosed herein may include a system and method for engaging in a technique for calibrating and/or boosting the accuracy of an arrangement of sensors positioned about a physical space. In one implementation, a method includes receiving from a primary sensor an indication of a particular location of a subject and receiving a first feature from a plurality of secondary sensors. The first feature may comprise a set of estimated locations of the subject. The method may further include resolving the first feature as being indicative of the particular location, receiving a second feature from the plurality of secondary sensors, identifying a match between the second feature and the first feature, and based on the identifying, determining a location of the new subject to be the particular location.

Abstract: Example systems and methods are disclosed for associating detected attributes with an actor. An example method may include receiving point cloud data for a first actor at a first location within the environment. The method may include associating sensor data from an additional sensor with the first actor based on the sensor data being representative of the first location. The method may include identifying one or more attributes of the first actor based on the sensor data. The method may include subsequently receiving a second point cloud representative of a second actor at a second location within the environment. The method may include determining, based on additional sensor data from the additional sensor, that the second actor has the one or more attributes. The method may include providing a signal indicating that the first actor is the second actor based on the second actor having the one or more attributes.

Abstract: A heat/vacuum molding system for molding a ski boot to a user's foot is provided. The system includes a heat source to heat an outer shell of the ski boot, a pliable plastic receptacle to receive the ski boot after the outer shell is heated by the heat source, and a vacuum system attached to the pliable plastic receptacle to create a negative pressure inside the pliable plastic receptacle to thereby collapse the pliable plastic receptacle to mold the ski boot to the user's foot.

Abstract: A pressure relief device is disclosed for a system containing a pressurized fluid. The device includes a main valve body having inlet and outlet flow ports and a valve plug positioned to seal the flowpath of the pressurized fluid between the inlet port and the outlet port of main valve body. A force transmission component is connected to the valve plug and an activation component is installed between the force transmission component and a mounting surface. The activation component is configured to prevent axial movement of the valve plug until a predetermined pressure is exerted on the valve plug. The force transmission component more efficiently transfers the output force acting on the valve plug to the activation component.

Abstract: The disclosed subject matter provides an improved methodology, system, and computer program for offering surveys and collecting and analyzing survey results that allow an organization to generate new surveys in an iterative manner based upon user feedback and crowdsourcing methodologies. In this manner, an organization relying upon survey results can gain greater insight into selected users, clients, and projects. The system according to the disclosed embodiments utilizes crowdsourcing methodologies to collect data from a variety of users and sources, whereby the data can be analyzed using innovative intelligence gathering and management techniques.

Abstract: A pressure relief device is provided. The pressure relief device includes a sealing member and a low-pressure support member that is adapted to provide support to the sealing member when the sealing member is subject to a certain pressure differential. The low pressure support member includes an annular flange and at least one supporting projection. A cutting element is adapted to puncture the sealing member when the sealing member is subject to a predetermined pressure differential. The pressure relief device may further include a high pressure support member and safety heads forming a pre-torqued assembly. The supporting projection may optionally include an area of weakness either wholly within or on the periphery thereof.

Abstract: An armor that is used, for example, in multi-cell missile launchers is disclosed. In some embodiments, the armor includes three layers. The inner-most layer undergoes explosive welding when exposed to a pressure wave from an explosion. An intermediate layer in-elastically deforms when exposed to the explosion. The third and outer-most layer includes a plurality of elongated, pressurized tubes that contain fire retardant, among other chemicals. Silicone gel is interposed between the tubes.

Abstract: An electrical connector that avoids some of the disadvantages associated with electrical connectors in the prior art. In particular, the illustrative embodiment of the present invention uses spring-loaded contacts to maintain connection in the presence of the vibration associated with a rocket launch, and also includes an environmental seal and electromagnetic shield so as to provide an environment for the electrical contacts that is isolated from the ambient environment and external electromagnetic radiation. Furthermore, the illustrative embodiment avoids the possibility of bent connector pins, which would make mating between the electrical connectors.

Abstract: An improved rupture disk assembly and methods and apparatuses for forming a rupture disk are disclosed. The rupture disk assembly includes a rupture disk having a flange connected to a dome-shaped rupturable portion by a transition area. The rupturable portion includes a structural apex formation at or near the apex of the dome and is configured to rupture when exposed to a fluid having a predetermined pressure. Preferably, a safety member is disposed adjacent the rupture disk. The safety member includes a hinge about which the disk bends when the disk ruptures. The present invention is also directed to an apparatus and method for consistently, accurately, and repeatably forming a structural apex formation in a rupture disk before the formation of to the rupture disk dome, during the formation of the rupture disk dome, and after the formation of the rupture disk dome.

Abstract: A pressure relief device for a sealed system is provided. The device includes a negative pressure support that is engageable with the system. A seal is disposed between the support and the system such that a negative pressure differential created in the system acts on the seal to move the seal away from the negative pressure support. A wire connects the seal to the support. The wire is configured to break, thereby releasing the seal, when the seal is exposed to a negative pressure differential having a predetermined level. The device may also include a positive pressure support disposed between the seal and the negative pressure support. The positive pressure support prevents the seal from releasing until the system experiences a positive pressure differential of a predetermined level. The device may also include a sensor that indicates when the seal has released.
