The BLED system includes an input buffer, a first flipping module, a first encoder, a second encoder, a second flipping module, and a transmit buffer.
Abstract:
A stowable computer workstation (“SCW”) for a workplace within a vehicle is described, where the workplace has an inner sidewall of the vehicle. The SCW may include a video display mount assembly and a deployment support attached to the video display mount assembly. The deployment support is configured to deploy and stow the video display mount assembly against the inner sidewall and the deployment support is secured to the inner sidewall.
Abstract:
Disclosed is a Radio Frequency (“RF”) Energy Harvesting System (“RFHS”). The RFHS includes a phased array antenna, a power harvesting unit, and a controller. The phased array antenna is configured to receive ambient RF energy and, in response, produce an input power signal. The power harvesting unit is in signal communication with the phased array antenna and includes a rectifier module, storage module, and power threshold module. The power harvesting unit is configured to receive the input power signal and, in response, produce a rectified power signal. The controller is in signal communication with the phased array antenna and may steer the antenna beam of the phased array antenna.
Abstract:
A telecommunication device includes a casing, smart phone components disposed within the casing, two opposed flexible wrist grips having upper and lower surfaces, and a flexible screen disposed on the lower surfaces of the casing and the opposed flexible wrist grips and in communication with the smart phone components.
Abstract:
A method for determining a geospatial location of a client in signal communication with a wireless array is provided. A magnetometer is used to provide geospatial orientation information relating to an orientation of a wireless array relative to the surface of the Earth. The geospatial orientation of the wireless array is determined based on the geospatial orientation information provided by the magnetometer. A transceiver in the wireless array that the client is in signal communication with is identified. The geospatial orientation of the transceiver that the client is in signal communication with is identified based on the geospatial orientation of the wireless array and the position of the transceiver in the wireless array. A geospatial direction of the client relative to the wireless array is calculated based on the geospatial orientation of the transceiver the client is in signal communication with and is used to identify a geospatial sector in which the client is located.
Abstract:
A system for quantifying the shadow fading observed in a wireless environment having multiple wireless access points is also provided. A distance determination module is in signal communication with the wireless access points. The distance determination module determines a distance between a pair of the wireless access points based on location information that relates to the locations of the wireless access points at the wireless environment. A shadow fading determination module is also in signal communication with the wireless access points. The shadow fading determination module determines a shadow fading factor based on the distance between a pair of the wireless access points and based on RSS information received from one of the wireless access points in the pair of wireless access points.
Abstract:
A broadband stacked multi-spiral antenna array comprising two or more spiral antennas with a dielectric layer having a generally uniform thickness positioned between each pair of stacked antennas, which are all center-fed and in-phase. The antenna array may be embedded in a non-conductive material, such as fiberglass embedded in a resin, a honeycomb core sandwich, or structural foam, that may be used to form a structural element of a mobile platform. The structural element may include a via providing a pathway for coaxial cables. If two structural elements are hatch covers on the port and the starboard sides of an aircraft, the use of a stacked multi-spiral antenna array in each structural element provides two roughly hemispherical coverage patterns which together provide an omni-directional coverage pattern. The stacked multi-spiral antenna array may also include a reflecting cavity placed at the bottom of one of the spiral antennas.
Abstract:
A lockout system for preventing a push-pull circuit breaker from being depressed while personnel work on de-energized electrical equipment. The lockout system includes an attachment member having a generally C-shaped collar defining a cylindrical recess integrated with a retainer member. The C-shaped collar is configured to resiliently expand in order to be positioned over and receive a cylindrical portion of an extended circuit breaker knob such that engagement of the circuit breaker is prevented. The retainer member includes a first channel member and a second channel member, each with a channel connected by a crossover channel that forms a continuous channel configured to receive a wire cable. Once inserted, the wire cable is firmly held in place by a locking chamber attached at each end of the wire cable, and thereafter, the lockout device can only be removed by a cutting the wire cable with a wire cutting tool.
Abstract:
A point-and-shoot automatic landing system (P-A-S ALS) realizes safety and mission effectiveness benefits in vertical takeoff and landing (VTOL) aircraft, allowing a pilot, using an inceptor device, to select an aim point with an aiming device providing visual indication of the aim point. Once a flight path is computed the pilot may allow the P-A-S ALS to automatically control the flight to touchdown. A suite of ranging devices determines the relative position of the aircraft to the selected aim point and an approach profile guidance algorithm computes the flight path. One or more devices provide confirmation that automatically controlled flight to the selected aim point is achievable. The P-A-S ALS is configured to allow termination of the controlled flight path at any time and selection of a new aim point through the inceptor device.
Abstract:
A system for annotating words of a data corpus based upon their particular concept and their corresponding grammatical sense with Conceptual Numerical Identifiers (CNIs) from a Conceptual Dictionary, pairing the words based on conceptual inter-relating network (CIRN) rules, and determining if a selected plurality of paired words are grammatically, syntactically, and linguistically correct by matching CNIs from each pair of words.
