A rosette or co-rotating vector scanning seeker detector array providing improved data rate and scanned field coverage. Several discrete detector elements are formed in an array on the detector surface in a coplanar arrangement, each of the detector elements providing target information when the scan sweeps across it. The array may be in the form of circular spots arranged around a central circular detector element. In an alternative embodiment, the central detector element is omitted and the peripheral detector elements are arranged sufficiently close together to preclude the likelihood of a target path passing between adjacent detector elements without being detected. Detector elements in a single array may be of different sizes and shapes.

An actively damped steering rate sensing device for an autopilot control system capable of producing angular rotation in a control plane of an intentionally continuously axially rolling airframe such as a homing missile in response to a rotation related guidance command signal. The device includes an elongated armature member mounted to the airframe for pivotal movement about an axis extending through the member intermediate its length. The pivot axis is oriented with respect to the rotational axis of the airframe so that the armature member will pivot by gyroscopic precession in response to rotation in the control plane of the rolling airframe. Sensing and damping coils are mounted on opposite ends of the armature member. Magnets and flux path return elements are fixedly mounted adjacent each of the coils. Movement of the armature member during flight produces an output signal in the sensing coil which is amplified and applied in the correct phase to the damping coil to damp the pivotal motion of the armature member.

A compound parallelogram four-bar linkage is provided wherein a first primary link is connected to a second primary link through connector links of substantially the same length and the pivotal angles of the first primary link and second primary link are maintained at substantially ninety degrees as movement is transferred from one primary link to the other so that the resonant frequency of the linkage does not vary and the linkage stiffness is independent of the angle of rotation.

Human powered vehicle

An improved golf cart is provided which comprises a frame bearing a seat having a high back, a pair of rear wheels flanking the seat and a front wheel, a set of foot cranks, a drive chain interconnecting the foot cranks and rear wheels, a steering assembly and a golf bag rack behind the back seat. To the upper part of the back rest are attached rearwardly extending rollers so that the cart can be tilted up to rest and ride on the rear wheels and rollers for compact storage and transport of the cart. An L-shaped support bracket may be secured to a car bumper for supporting and transporting the cart in the tilted up position. The cart may include an arm depending from the frame and engageable with the bracket and connectors to aid in holding the cart on the bracket. The cart can also include gears, a gear shift mechanism, brakes and a brake lever. The steering assembly can include a transverse bar pivoted to the frame below the front of the seat, and a forwardly extending link rod pivoted at one end to the bar and at the opposite end to one side of the fork holding the front wheel. The bar bears spaced handles, so that pivoting of the bar pivots the front wheel. The bar-frame pivot point and the link-bar pivot point are on opposite sides of the longitudinal axis of the frame. The cart is simple, durable, inexpensive, offers good exercise and is easy to move about, store and transport.

Golf cart

A human powered vehicle of the pedal-driven type having three or more wheels, a frame and seat for supporting one or more riders in a generally supine position, and a streamlined shell enclosure with a transparent canopy which is openable for entry and egress of the rider. The preferred embodiment for a single rider has two steerable wheels located forward of the rider at approximately the widest part of the streamlined shell, and a single fixed drive wheel centrally positioned behind the rider. The drive wheel is equipped with a multi-sprocket gearing arrangement, and a large pedal-equipped sprocket wheel is mounted in a position slightly forward and above the common axis of the front wheels for ready engagement by the rider's feet. A single drive chain extends from the drive sprocket to the sprocket cluster and passes around idler rollers which direct the chain beneath the rider.

Apparatus for scanning the field of view of an optical objective. A primary mirror is mounted for rotation about a spin axis. A secondary mirror supports an electrical motor magnet and is mounted for rotation about the spin axis. A non-rotating stator is mounted behind the secondary mirror and supports the electric motor coils. The primary and secondary mirrors are canted slightly out of perpendicularity with the spin axis. The primary and secondary mirrors and the electric motor stator are fully gimbaled for tracking a target. The scanning patterns of the primary and secondary mirrors combine to scan a rosette pattern across a sensor.
