Abstract: Disclosed is a recumbent bicycle having a frame with at least one tubular member having a lumen. Mounted to the frame are a rear wheel assembly and a transmission assembly. The transmission assembly can include a first gear, a second gear, and a chain that extends from the first gear to the second gear and through the lumen of the at least one tubular member. Pedals and crank arms can mount to the second gear, which is slidable relative to the first gear to vary the position of the second gear relative to a seat mounted to the frame. A suspension assembly can mount a pair of front wheels to the frame at a location intermediate of the first portion and the second portion of the frame. The bicycle enables riders of different leg lengths to use the recumbent bicycle, while the suspension assembly cushions the rider during use.

Abstract: A lifting system is used to move an item between a use position and a stowed position in a vehicle. The item may be an article of furniture, an appliance, a storage unit, a platform, or the like. The lifting system may be motorized and/or utilize a flexible drive to move the item. The lifting system may be used to reciprocally move the item between the use position and the stowed position in a recreational vehicle.

Abstract: A vehicle such as a recreational vehicle includes a slide-out portion such as a slide-out compartment, slide-out patio, etc that moves between a retracted position and an extended position to increase the living space in the vehicle. The slide-out portion includes a second floor that is positioned adjacent to a main floor when the slide-out portion is retracted. A slide-out mechanism is used to move the second floor between the retracted position and the extended position. The second floor may be at least substantially flush with the main floor when the slide-out portion is in the extended position.

Abstract: A vehicle includes a bed that is configured to move between a sleeping configuration and a seating configuration. The bed is also configured to move vertically between a use position and a stowed position.

Abstract: A vehicle includes a cargo area which is configured to receive an off-road vehicle. The vehicle may include a bed which moves vertically between a use position and a stowed position. The vehicle may also include a seating unit which moves vertically between a use position and a stowed position. The vehicle may also include another item which moves vertically between a use position and a stowed position. The another item may include an article of furniture, an appliance, a storage unit, or a sink.

Abstract: A vehicle includes a main floor and a slide-out portion which includes a slide-out floor. A flush floor slide-out mechanism may be used to move the slide-out portion between a retracted position where the slide-out floor is positioned adjacent to the main floor and an extended position where the slide-out floor is at least substantially flush with the main floor.

Abstract: The degree of polarization of an optical signal is measured by a polarimeter and used for providing a feedback signal to adjust adaptive optics of a polarization mode dispersion compensator. The polarization properties of the polarimeter are determined with high accuracy to match the polarimeter through calibration and used to produce the feedback signal.

Abstract: A system and method for synchronizing a plurality of main processors. At a first time and in response to a first time reference, a first rendezvous signal is sent from a first to a second of the plurality of main processors. At a second time, and in response to a second time reference, a second rendezvous signal is sent from the second of the plurality of main processors, to the first of said plurality of main processors. After the first rendezvous signal is received by the second of the plurality of main processors and the second rendezvous signal is received by the first of said plurality of main processors, substantially simultaneous scanning of control information is initiated by the first and second of the plurality of main processors. In variations, a difference between the first and second times signals a fault condition.

Abstract: A vehicle includes a slide-out compartment and a sliding mechanism which is used to move the slide-out compartment between an extended position and a retracted position. The sliding mechanism uses a guide member, a sliding member, and a gear to move the slide-out compartment between the extended position and the retracted position.

Abstract: A sliding mechanism for moving a slide-out compartment of a vehicle includes a guide member, a sliding member, and a gear. The gear is used to move the sliding member relative to the guide member. The sliding member and the guide member cooperate with each other to move the slide-out compartment between an extended position and a retracted position.

Abstract: A vented soffit panel and related method for buildings and the like includes a generally flat imperforate base portion shaped to enclose at least a portion of the building soffit when mounted in a generally horizontal orientation under an eave. At least one vent channel protrudes upwardly from the base portion, and has a generally trapezoidal shape defined by a horizontal imperforate top wall and inclined perforate sidewalls with lower ends that connect with the base portion in a spaced apart relationship to define a slot through which air flows to vent the eave. The perforate sidewalls are disposed at an acute angle, such that they are hidden from view from a position underneath the eave.

Abstract: A polarization converter followed by two PMFs adjusts principal states of polarization (PSP) of a PMD compensator against PSP of an optical transmission line, and a mode-coupling adjuster between the PMFs adjusts a differential group delay and a PSP rotation rate of the PMFs.

Abstract: A quick-release mechanism that allows a motor to be quickly and easily released from a motorized activation assembly to activate a sliding mechanism thereby extending or retracting a slide-out compartment of a recreational vehicle.

Abstract: A structure is described which includes a bed and an apparatus having a flexible drive member which moves along an endless path. The apparatus is coupled to the structure and to the bed, and the apparatus is used to vertically move the bed along the endless path.

Abstract: An apparatus comprises an edge detector, a memory and a pulse-input engine. The edge detector is configured to receive an input signal and a counter signal. The edge detector is further configured to send a set of time values based on the input signal and the counter signal. Each time value from the set of time values is uniquely associated with a detected edge transition from the input signal. The memory is coupled to the edge detector. The memory is configured to receive from the edge detector the set of time values. The memory is configured to store the set of time values. The pulse-input engine is coupled to the memory. The pulse-input engine is configured to measure a set of pulse-to-pulse delays based on the set of the time values stored in the memory.

Abstract: A control system for executing an application program is disclosed herein. The control system includes a plurality of main processor modules. The control system further includes a plurality of input/output modules for providing input process data to associated ones of the plurality of main processor modules. A voting system is operative to compare the input process data associated with first and second of the plurality of main processor modules to the input process data associated with a third of the main processor modules. This results in generation of voted input process data utilized by the third main processor module in executing the application program. In certain implementations the system includes a high-speed bus for distributing the voted input process data to the first and second main processor modules, each of which also executes the application program based upon the voted input process data.
