Abstract: A multi-component idler or pulley that may be used with a belt and pulley system of an automobile is disclosed. The multi-component idler may have an external idler housing coupled to a mounting hub that is designed to be connected to a mounting surface of the belt and pulley system. The axial position of the external idler housing may be adjustable relative to the mounting hub using a threaded engagement or a plurality of shims between the components. The external idler housing and the mounting hub may be fastened to each other by bolts once their positions are adjusted relative to each other. Different types of external idler housing may also be used with the mounting hub. In this way, the serpentine belt of the belt and pulley system may be adjusted based on the user's needs.

Abstract: An apparatus for tying knots can include a body defined by a length along a longitudinal axis of the body and by an outer surface that extends around the longitudinal axis of the body from a first end of the body to a second end of the body. A trench in the body can extend from the outer surface of the body toward the longitudinal axis for the length of the body. A channel can extend for the length of the body and is exposed at the first and second ends of the body. A neck can be between the trench and the channel, the neck can be configured to contain first and second flexible lines extending in the channel extending from the first end of the body to the second end of the body and a line guide can be on the outer surface of the body configured to hold the first or second line at an oblique angle relative to a direction of the longitudinal axis.

Abstract: In some implementations, a battery manager may identify a first voltage rating of a first battery pack. The battery manager may configure, based on the first voltage rating, a resistor bank of the battery manager to have a first resistance value. The battery manager may perform, via the resistor bank having the first resistance value, a first discharge operation, associated with the first battery pack, having a first duration. The battery manager may identify a second voltage rating of a second battery pack. The battery manager may configure, based on the second voltage rating, the resistor bank of the battery manager to have a second resistance value. The battery manager may perform, via the resistor bank having the second resistance value, a second discharge operation, associated with the second battery pack, having a second duration, and a difference between the first duration and the second duration satisfying a time threshold.

Abstract: A firearm having a laser induced friction surface. A method for forming the laser induced friction surface on the firearm may includes the steps of disposing the laser machine adjacent to a component of the firearm, adjusting the laser machine, then applying the laser beam of the laser machine onto a component surface.

Abstract: A fastening tool having a socket and a socket wrench with laser induced friction surfaces or lines on the outer surface of the socket is described herein. The laser induced friction surfaces may have a plurality of kerfs with recast material to increase the coefficient of friction on the outer surface of the socket. As a result, the user of the fastening tool may pull the socket off a head of a fastener with his or her hands instead of having to dislodge the socket first with a blunt object, such as a hammer. It is contemplated that the socket wrench may have laser induced friction surfaces or lines also.

Abstract: Provided herein are various magnetoelectric dipole antenna arrays and multi-array arrangements for handling radio frequency signals. In one example, an antenna array includes a baseplate conductively coupled to sets of plate elements by support members that position the plate elements at selected distances offset from a surface of the baseplate. Antenna probes are arranged in orthogonal pairs positioned within gaps between a corresponding set of plate elements, with each antenna probe comprising a conductive strip having a feed section coupled to a radio frequency connection through the baseplate, a transverse section generally parallel with the baseplate, and a terminal section directed back toward the baseplate. Dielectric structures for each pair of antenna probes comprise a dielectric material having channels that recess the conductive strips therein and a dielectric spacer positioned between overlapping transverse sections of the antenna probes.

Abstract: Techniques of modifying user interfaces associated with a browser application includes enabling a user to modify a web page as displayed by the web browser in a way not anticipated by the creators of the web page elements and without needing to understand the internal structure of the web page. For example, improved techniques implemented as part of the technical solution would allow a participant in a web meeting to emphasize the names of other participants having the same manager without knowing anything about the architecture or programming code associated with the web meeting application.
