Abstract: Systems, methods, and devices are disclosed for surgical instruments, systems, and methods for preventing skiving of a drilling instrument during a robotic or robot-assisted surgery are disclosed. In one embodiment, a scan of a patient's anatomy can be performed to produce a model of the bone to be drilled into and analysis of the surface can determine if the curvature is such that, if a target trajectory for a bore were followed, skiving of the drilling instrument is likely. If so, an alternate anti-skiving trajectory can be determined. The anti-skiving trajectory of a bore differs from the target trajectory by at least one of entry point, diameter, axis, or depth.

Abstract: An insulator for welding a boss onto a member is provided. The insulator includes a body comprising a first surface and a second surface. The second surface includes a first curved profile. The insulator also includes a bore extending between the first surface and the second surface to define an inner wall of the body. The insulator further includes a protrusion in the inner wall proximal to the second surface. The protrusion, in the insulator, includes a second curved profile.

Abstract: A pin and bearing assembly including a pair of pins, each pin having a frustoconical portion, a pair of sleeve bearings configured to rotate relative to the pair of pins, a pair of rings configured to couple the pair of sleeve bearings to a hub, and a thru rod having a nut on a first end wherein when the nut is tightened a compressive force is applied to the pair of pins and pair of sleeve bearings.

Abstract: A method of performing packet level transmission scheduling in a communications systems including a plurality of cells, each cell including a base station and plurarity of mobile stations. The method performs scheduling while considering radio resource allocation at the wireless access node. In a schedule plan phase of the method, average power and average effective data rate are determined for all mobile stations in the system. In addition, the planned fractions of frames ? that each mobile in the system will transmit is determined so that resources are allocated fairly. In the actual schedule phase of the method, current power and effective data rate values are compared to the average power values. This information along with the ? values is used to determine the actual schedule of packet transmissions for all mobiles in a particular cell.

Abstract: An automatic dispensing toothbrush is provided including a toothpaste dispenser having a coaxial bore formed along a length thereof for housing toothpaste. A ball screw is rotatably coupled in concentric relationship within the bore of the toothpaste dispenser. A ball nut plunger is screwably coupled to the ball screw and adapted to raise within the toothpaste dispenser upon the rotation of the ball screw. A rotator is rotatably coupled within the bore of the toothpaste dispenser adjacent to a bottom thereof and further coupled to the ball screw for rotating the same. Also included is a toothbrush assembly including a hollow linear rod removably coupled to the toothpaste dispenser. The toothbrush assembly further includes a plurality of bristles extending horizontally from an upper extent of the hollow rod and at least one bore formed therein. The toothbrush assembly is threadedly coupleable to the toothpaste dispenser for receiving toothpaste therefrom.

Abstract: A hinge mechanism for a door on an overhead baggage compartment which is generally located in the passenger section of an airliner and utilized by passengers for the stowage of carry-on luggage. The door hinge mechanism comprises, an unequal length four-bar linkage mechanism which produces a compound motion to the door for swinging it into the standing room area of the passenger section when it is moved to the open position. An ordinary four-bar linkage mechanism would have two pairs of equal length links and their operation would be designed around two fixed pivot points. However, in this disclosure there is only one fixed pivot point and the other of the generally fixed pivots, is a walking pivot which is guided by a cam device to profile the travel of the door.

Abstract: A hinge mechanism for an overhead baggage compartment which is generally located in the passenger section of an airliner. The hinge mechanism comprises, a dual-cam guided four-bar linkage mechanism which produces a compound motion to the door for retraction through a relatively narrow horizontal opening into an area above the baggage compartment. Ordinarily, a four-bar linkage mechanism would have its operation designed around two fixed pivot points; however, in this disclosure there is only one fixed pivot point and the other of said pivots is a walking pivot which is guided by a dual-cam device for profiling the travel of the door.

Abstract: A method for color dyeing nylon articles and the like utilizing a room temperature dye solution comprises mixing a dyestuff with formic acid to form a dye solution such that the final solution contains 30-60% formic acid in an aqueous solution by volume, applying said dye solution to the area of the nylon article to be colored, and after the dye solution has remained on said article for a predetermined length of time, rinsing the article.
