Abstract: A hands free drill guide includes a handle having a proximal handle end portion, a distal gripping end portion, and a longitudinal through-passage extending between the proximal end portion and the distal gripping end portion. The distal end portion includes two legs extending along either side of the through passage. A method of using the drill guide is also provided.

Abstract: A retaining plate with locking mechanism assembly includes a retaining plate having a first screw hole extending therethrough and a spring blocker rotatably mounted in plate proximate to the first screw hole. The spring blocker includes a body portion, a first land extending radially from the body portion above the retaining plate, and a first wing extending tangentially from the first land in a first arc. When a first screw is inserted into the first screw hole, when the spring blocker is rotated to a first position, the first land extends over a portion of the first screw. When the spring blocker is rotated to a second position, the first wing extends over the portion of the first screw. When the spring blocker is rotated to a third position, neither the first land nor the first wing extends over the portion of the first screw.

Abstract: A system for performing interbody fusion surgery including an expandable intervertebral spacer and specialized instruments for choosing the correct size of implant, implanting the device within the intervertebral space, and for delivery of bone graft or bone substitute to the interior of the implant.

Abstract: A bone fusion assembly includes a bone plate having a plurality of through openings extending therethrough. The through openings include at least one fusion screw opening sized to allow a screw guide to be at least partially inserted therein and a plurality of fixation screw through openings. The screw guide includes a body having a proximal end, a distal end, and a through-passage extending between the proximal end and the distal end. A K-wire a sized to extend through the through-passage in the body of the screw guide.

Abstract: A panel attachment member and system for shielding a vehicle in an off-road setting. The panel includes an exterior portion and an interior portion. A lip is disposed around the interior portion. A magnetic cut-out is attached to the lip for magnetically securing the panel to the vehicle. Moreover, at least one suction cup is disposed on the interior portion for further securing the panel to the vehicle via vacuum pressure contained within the suction cup. A valve is attached to the suction cup for releasably securing the panel to the vehicle.

Abstract: A radar of particular use at close range has a CRT that is scanned in a spiral fashion by applying phase quadrature sinusoidal signals to resonant deflection coils. A digitizer converts the radar return signals to multi-bit signals which are supplied to a memory with signals for alternate pixels stored in different halves of the memory. The apparatus reads out signals from one half of the memory during one scan and reads out signals from the other half of the memory during the next scan so that they are interleaved with the pixels on the display brightened by the first scan.
