Abstract: An apparatus is described for burn-in and/or functional testing of microelectronic circuits of unsingulated wafers. A large number of power, ground, and signal connections can be made to a large number of contacts on a wafer. The apparatus has a cartridge that allows for fanning-in of electric paths. A distribution board has a plurality of interfaces that are strategically positioned to provide a dense configuration. The interfaces are connected through flexible attachments to an array of first connector modules. Each one of the first connector modules can be independently connected to a respective one of a plurality of second connector modules, thereby reducing stresses on a frame of the apparatus. Further features include for example a piston that allows for tight control of forces exerted by terminals onto contacts of a wafer.

Abstract: An adjustable support assembly for an orthopedic brace has a support arm, a housing and a locking mechanism. The housing includes a travel track which slidably receives the support arm. The locking mechanism includes a lock lever which selectively applies a sufficient force to the support arm to prevent slidable displacement of the support arm in the travel track.

Abstract: An orthopedic brace is provided with an adjustable support assembly having a support arm, a housing and a locking mechanism. The housing includes a travel track which slidably receives the support arm. The locking mechanism includes a lock lever which selectively applies a sufficient force to the support arm to prevent slidable displacement of the support arm in the travel track. The orthopedic brace is further provided with a hinge having a first rotation plate, a second rotation plate, a pivotal connector connecting the first and second rotation plates, a rotation limiting mechanism, and a rotation locking mechanism.

Abstract: An adjustable support assembly for an orthopedic brace has a support bar, a housing and a locking mechanism. The housing includes a travel track which receives the support bar. The locking mechanism includes a lock stop and a lock peg array having at least one column and a plurality of rows. The lock stop is perpendicularly positioned between two lock pegs in adjacent rows to prevent displacement of the support bar in the travel track when the length locking mechanism is in the closed position and the lock stop is parallely positioned to enable displacement of the support bar in the travel track when the length locking mechanism is in the open position.

Abstract: An imaging device that automatically rotates upon descent through an atmosphere provides an onboard image detector a sweeping panoramic scan as it descends. No moving parts or propulsion system are required. The location, angle and pitch of the winged structure, together with its inertia properties, passively induces rotation. The angled location of the image detector takes advantage of the resulting rotation. Data generated by the image detector may be transmitted to a remote receiver or, alternatively, stored for subsequent recovery.

Abstract: An efficient aircraft utilizes a stabilizer spaced from a fixed wing, and supported for controlled rolling about an axis extending generally in a forward direction, to control aircraft yaw. The stabilizer extends generally horizontally in straight forward flight. Pitch of the stabilizer is also controlled.
