Abstract: Media is distributed via a scalable ad hoc geographic routing/broadcast protocol. Media can be transmitted from a mobile device to a cluster of mobile devices that are geographically located in a particular region. Devices that are located between the source and the intended target can act as routers with the ability to forward data packets toward the intended destination. In essence, a geocast network cloud is established, allowing any device within the cloud to communicate with any other device in the cloud. Devices in the network can constantly change position and the transmission path through the network can be constantly changing. The geocast protocol adapts to the changing conditions.

Abstract: A skinning knife, comprising a handle, a slitting blade disposed at a forward portion of the handle and having an upwardly- and forwardly-directed cutting edge, a first spreading member disposed at the forward most position of the knife so as to spread apart two portions of animal hide that have been separated by the slitting blade, and a retractable punch blade disposed in the handle beneath slitting blade for opening a hole in the hide, the first spreading member having a slot therein for receiving the punch blade. A punch blade actuation mechanism is provided for moving the punch blade through the slot in the first spreading member. Preferably, a second spreading member disposed below and forward of the first spreading member is provided for facilitating entry into a small slit.

Abstract: A skinning knife, comprising a handle, a slitting blade disposed at a forward portion of the handle and having an upwardly- and forwardly-directed cutting edge, a first spreading member disposed at the forward most position of the knife so as to spread apart two portions of animal hide or other material that have been separated by the slitting blade as the knife is thrust forwardly, and a retractable punch blade disposed in the handle beneath slitting blade for opening a hole in the hide when the knife is thrust forwardly, the first spreading member having a slot therein for receiving the punch blade. A punch blade actuation mechanism is provided for selectively moving the punch blade forwardly and rearwardly through the slot in the first spreading member. Preferably, the skinning knife also comprises a second spreading member disposed below and forward of the first spreading member for facilitating entry into a small slit.

Abstract: A skinning knife comprising a handle, a convex skinning blade, and one or more spreading members disposed at the forward most position of the knife so as to spread apart two portions of an animal hide that have been separated as the knife is thrust forwardly. A preferred embodiment also features a slitting blade disposed at a forward portion of the handle and having an upwardly- and forwardly-directed cutting edge, and a retractable punch blade disposed in the handle beneath the slitting blade for opening a hole in the hide when the knife is thrust forwardly, the first spreading member having a slot therein for receiving the punch blade. A blade actuation mechanism is provided for selectively moving the punch blade forwardly and rearwardly through the slot in the first spreading member. In alternative embodiments, an actuation mechanism moves the skinning blade or the spreading member.
