Abstract: A stereographic panoramic media (SPM) can be received. The media can include a 360 degree field of view (FoV) within the horizontal plane and a usable FoV within the vertical plane. A first, second, and third field of view associated with the SPM can be identified. The first FoV can be 180 degree field of view and the second and third FoVs can encompass 90 degree FoV within the horizontal plane. The SPM can be translated to a cylindrical panoramic media (CPM). The CPM can conforms to a three dimensional hollow cylindrical projection (CP). The first FoV of the SPM can be mapped onto the inner surface of the CP, and the first and the second field of view can be mapped onto the outer surface. The CPM can provide a visible continuous field of view of at least 270 degrees.

Abstract: A system of an alert puck, a mobile communication device, and an alert server for facilitating a VOIP session with the mobile communication device responsive to an emergency event triggered by the alert puck. The alert puck comprises a housing enclosing a sealed volume, a power supply and control circuitry that includes a personal area network (PAN) interface. The mobile communication device comprises an operating system, an alert application executing upon the operating system, and a wireless transceiver. The alert server contacts a set of one or more previously defined contact devices, conveys an emergency message, and facilitates the VOIP session with the alert application, when a button is pressed on the alert puck.

Abstract: A flexible cutting tool includes a substantially cylindrically-shaped housing having a first end and a second end. The first end includes a hollowed region. A substantially cylindrically-shaped bushing, having a first face and second face and including a flexible material, is sized such that the first face and at least a portion of the bushing are secured inside the hollowed region of the housing. The bushing includes a bore extending through the first face, the second face, and an axis of the bushing. A cutting tool includes a cutting edge, a stop, and a shaft between the cutting edge and the stop. A diameter of the stop is larger than a diameter of the bore for allowing the stop to enter the second face of the bushing, frictionally pass through the bushing and exit the first face of the bushing. A diameter of the shaft is smaller than the diameter of the stop and larger than the diameter of the bore such that the bushing frictionally engages the shaft.
