  • Patent number: 7562674
    Abstract: A security enclosure (20) for a control apparatus (22) is disclosed. The enclosure (20) is formed of a cage (28) connected to a base (30). Opposing mounting straps (36) partially embedded within the base (30) extend inside the cage (28) through strap engagement slots (58). The cage (28) has cage lock holes (72) that align with strap lock holes (70) in the mounting straps (36), and through which a lock device (74) is passed to secure the cage (28) to the mounting straps (36) and the base (30). The shackle (86) of a lock (88) is passed through a hole (82) in a movable lock tab (78) on the lock device (74) and a hole (84) in a fixed lock tab (80) affixed to the cage (28). When the lock (88) is closed, the lock device (74) is secured and the cage (28) cannot be removed from the base (30) without opening the lock (88). The lock (88) and the lock tabs (78,80) are protected by a shroud (90) affixed to the cage (28). End panels (26) and a perforated body panel (24) complete the cage (28).

  • Patent number: 7469491
    Abstract: A digital communications transmitter (100) includes a digital linear-and-nonlinear predistortion section (200, 1800, 2800) to compensate for linear and nonlinear distortion introduced by transmitter-analog components (120). A direct-digital-downconversion section (300) generates a complex digital return-data stream (254) from the analog components (120) without introducing quadrature imbalance. A relatively low resolution exhibited by the return-data stream (254) is effectively increased through arithmetic processing. Distortion introduced by an analog-to-digital converter (304) may be compensated using a variety of adaptive techniques. Linear distortion is compensated using adaptive techniques with an equalizer (246) positioned in the forward-data stream (112). Nonlinear distortion is then compensated using adaptive techniques with a plurality of equalizers (226) that filter a plurality of orthogonal, higher-ordered-basis functions (214) generated from the forward-data stream (112).

  • Patent number: 7467095
    Abstract: A computer program for strategic planning and optimization allows a user to model an enterprise to visualize an effect of a strategic constraint on a primary goal of the enterprise. The primary goal is represented by a primary objective function which, in turn, depends upon a set of operational variables. The strategic constraint is represented by a constraint function that depends upon a subset of the operational variables. An effective objective function is constructed by combining the primary objective function and the constraint function, and the effective objective function is optimized over a range of target values for the constraint function. An outcome of the primary objective function is determined for each target value, and a graphical view of the outcome for each of the target values is presented. The graphical view provides a visualization of the effect of the strategic constraint on the primary goal for managing the enterprise.

  • Patent number: 7428919
    Abstract: A heat exchanger evaluation system (84) includes a refrigeration subsystem (126) and a platform (94) in communication with the subsystem (126) for attachment of a heat exchanger (32). The system, (84) further includes a thermal imaging camera (168) and a monitor (100). A method (180) entails routing a fluid (38) through the heat exchanger (32) via the refrigeration subsystem (126). The camera (168) detects the temperature variation across the heat exchanger (32) as the fluid (38) flows through the heat exchanger, and provides successive thermal images representing the temperature variation responsive to the flow of the fluid (38). The thermal images are utilized to determine an efficacy of the flow through the heat exchanger (32). In particular, a determination can be made as to whether the flow deviates from a pre-determined flow path (79) of the fluid (38) through the heat exchanger.

  • Patent number: 7404580
    Abstract: A hollow walled structure (22) includes a shell (36) having a wall defining an interior compartment (46). A first support, in the form of a baffle (48), is disposed within the interior compartment (46) and engages the shell (36) at two locations (52, 54). A second support, in the form of a post (83), engages the shell (36) and extends through the interior compartment (46) to intersect the baffle (48). The shell (36), baffle (48), and post (83) are formed concurrently from a thermoplastic material by a rotational molding process. The rotational molding process can entail operations of pre-heating interior portions of the mold, delivering heat to the interior portions of the mold, and/or filling the mold with excess thermoplastic material prior to preheating the mold. The rotationally molded structure (22) has sufficient strength to function as a tank for carrying a liquid (34) in a liquid transport apparatus (20).

  • Patent number: 7376418
    Abstract: A satellite communications system (10) includes a hub (14), a satellite (32), and any number of remote terminals (16). Each remote terminal (16) includes a remote receiver (38), a monitor (40), and a network access controller (42). Each remote receiver (38) is configured to receive and down convert the system's entire spectrum of interest from which channels are accessed by the remote terminals (16). The monitors (40) independently perform FFT processes over this entire spectrum, but at a low frequency resolution which is no higher than needed to distinguish channels. Based on these spectral analyses, uplink/inbound channels are independently selected by the network access controllers (42) at each remote terminal (16). Remote terminals (16) immediately transmit data to the hub (14) as soon as they select an uplink/inbound channel.

    Abstract: A system (22) for orienting an object (28) relative to a base (24) to which the object (28) is rotatably coupled includes a braking surface (46) in fixed relation with the base (24). A brake (48) is engaged with the braking surface (46). A linear actuator (82) has a body (86) in fixed attachment with the object (28) via a strap member (84) and a coupling element (80). The linear actuator (82) also includes a rod (88) in fixed communication with the brake (48) through an elongate member (90) that flexes in response to a braking force (66) imposed on the braking surface (46) by the brake (48). The linear actuator is activated to generate linear motion (120) of the rod (88). The linear motion (120) of the rod (88) causes rotational motion (122) of the object (28). The strap member (84) is enabled to flex as the object (28) rotates.
