Abstract: The emergency egress apparatus includes a protuberance mated to a first portion of the door barricade and a keeper mated to a second portion of the door barricade. A retainer is selectively disposed between one of two positions. A first position defines the placement of the retainer that establishes an interference fit between the protuberance and the keeper. A second position defines the placement of the retainer such that it is not in contact with the protuberance or the keeper. The first position secures the first portion of the door barricaded with respect to the second portion of the door barricade, and the second position decouples the first portion of the door barricade with respect to the second portion of the door barricade.

Abstract: Removable hands-free door pull openers are disclosed that can be attached to doors without penetrating the surface of the door. The door pull opener includes a door clamping portion configured to clamp the free edge of a door that receives a lock, and a hook portion joined to the door clamping portion. The hook portion includes a bend portion and is configured for a person to insert their forearm between one side of the door and the bend portion so that they may pull open a door without touching the door or the door pull opener with their hand. A foot pull door opener is also provided. A door latch bolt cover that covers a door latch bolt is also disclosed.

Abstract: A method includes receiving relative position data from a laser range finder, where the relative position data includes a distance and a relative angle between a first node and a second node measured by the laser range finder from a first position of the first node. The method may also include computing a second position of the second node based on the relative position data, providing the second position of the second node to a computing device of one or more of the first node and the second node, and computationally reconstructing a route traversed by the first node and the second node from a number of computed positions for the first node and the second node based on data received from the laser range finder.

Abstract: A method of collecting information about a plurality of test devices connected in a network is provided. The method includes: identifying routable network addresses within a plurality of the network addresses, and sending discovery packets to the plurality of routable network addresses, receiving responses from the test devices, obtaining the information about the test devices, and storing the information so as to associate, for each of the test devices, the test-device information with at least one of the routable network addresses. The routable network addresses are stored in non-volatile memory for repeated use in re-discovery of the test devices in the network.

Abstract: A door barricade apparatus includes a blade with a barb at a distal end and a tang at a proximal end. The barb is configured to be disposed within an aperture of a strike plate. A body has a top and a bottom, and the body is operably coupled to the tang of the blade. A paddle is moveably coupled to the body and is configured to selectively move between a first orientation substantially flush with the top of the body and a second orientation protruding from the top of the body. A handle is coupled to the bottom of the body and is configured to keep a user's fingers away from a door jamb. An actuator is in cooperation with the paddle, and is configured to selectively position the paddle between the first orientation and the second orientation.

Abstract: A system and method of using the system are provided. The system can include at least one source, a plurality of sensors, and a processing device. The source can emit one or more low frequency sounds. The sensors can sense the low frequency sounds and transform the low frequency sounds into one or more signals including a plurality of data values. The processing device can be communicatively operable with the sensors to receive the signals and determine positioning information of the sensors based on the data values.

Abstract: A method for creating a compound media stream includes obtaining a first media segment, obtaining a first matching criterion, and automatically associating the first media segment with an existing media stream to produce the compound media stream.
