Abstract: A fire-rated receiver channel includes at least one intumescent or other fire-resistant material strip. The receiver channel can nest with a framing member, such as metal tracks, headers, header tracks, sill plates, bottom tracks, metal studs, wood studs or wall partitions, and placed at a perimeter of a wall assembly to create a fire block arrangement. In other arrangements, a track assembly includes two nested tracks, an inner track and outer track. The assembly is designed so that the outside width of the outer track is equal to or less than the outside width of the inner track to present a substantially flush external surface for attachment of exterior sheathing elements when the assembly is used in an external wall.

Abstract: The present application is directed toward fire-rated wall construction components and wall systems for use in building construction. Embodiments can include tracks for holding studs which incorporate various geometries capable of receiving fire-retardant material, flat straps for use between tracks and fluted wall components, fire sponges for use in fluted wall components, and tracks with protruding grooves or other structures which prevent unwanted air movement between a wallboard component and the track.

Abstract: In accordance with an embodiment, a synchronous N pulse burst generator includes an input for an intermediate frequency trigger signal and a signal path extending from the input. The signal path includes a series of N AND gates and an OR gate. Each AND gate is arranged to receive two inputs from the signal path. The signal path introduces a time delay between the two inputs received by each AND gate. A second input of the two inputs is inverted. The signal path introduces the time delay between successive AND gates from the series of N AND gates. An OR gate receives outputs from the series of N AND gates and outputs an A/D clock signal.

Abstract: In accordance with presently disclosed embodiments, systems and methods for sequencing portable containers of bulk material to provide continuous bulk material usage at an outlet are provided. The disclosed sequencing techniques may involve identifying a sequence for opening different portable containers of bulk material (or identifying the “next” portable container to open) and automatically actuating the discharge gates of the portable containers in the desired sequence to provide a continuous flow of bulk material to the outlet (e.g., blender unit). The identified sequence may be executed through a control system communicatively coupled to actuators used to open/close the discharge gates of the portable bulk material containers. A GUI may be communicatively coupled to the control system to allow an operator to select the desired sequence for execution by the control system and to display information regarding the portable bulk material containers.

Abstract: A network system uses the capabilities of client devices to search for objects in an image within a geographic region. The network system receives a request to search for an object and a geographic region within which to search the object. The network system provides instructions to client devices within the geographic region to search for the object. Upon receiving instructions to search for the object, the client device captures visual data of the area around the client device. The client device analyzes the visual data to detect the object and notifies the network system if the object is detected.

Abstract: A method of eliminating spurs in measurements of an electrical response of a device under test (OUT) obtained uses a measurement instrument including a mixer and a receiver. The measurement instrument is configured to generate, via the mixer, an intermediate frequency (IF) signal for use by the receiver from a radio frequency (RF) signal and a local oscillator (LO) signal. Input is received from a user at the measurement instrument and includes start frequency and end frequency. Parameters for a frequency sweep are generated based on the input. A measurement for each frequency of the frequency sweep is calculated using averaging of a plurality of samples obtained at that frequency. Frequencies are identified within the frequency sweep at which spurs will occur due to the measurement instrument. The parameters for a frequency of the frequency sweep at which a spur will occur are modified so that a null for a measurement at the frequency falls on the spur.

The synchronization signal is converted to an optical signal by the optical transceiver and transmitted from the first free space transceiver to the second free space transceiver. The second coupler converts the optical signal to the synchronization signal and a clock signal of the receiver is locked to the synchronization signal.
