Abstract: In an example in accordance with the present disclosure, an extended reality system is described. The extended reality system includes an imaging system to present virtual objects to a user. The extended reality system also includes a machine vision tracking system. The machine vision tracking system includes a camera to capture images of a user's hand a tool grasped in the user's hand. The machine vision tracking system also includes a processor. The processor 1) tracks a position and orientation of the user's hand in physical space, 2) identifies the tool grasped in the user's hand, and 3) tracks a position and orientation of the tool in physical space. The extended reality system also includes an XR controller to manipulate the XR environment based on the position and orientation of the tool and the position and orientation of the hand.

Abstract: Systems and methods are described for monitoring fluid flow through a conduit. A method comprises conveying a fluid in a conduit so that the fluid impinges upon an impingement within the conduit and sensing a temperature with a heated temperature sensor that is thermally coupled to the conduit to provide a heated temperature measurement. The method also includes heating the heated temperature sensor with a heater and sensing a temperature of the fluid at a location of the conduit that is thermally isolated from the heater to obtain a reference temperature measurement. An indication of a flowrate of the fluid is provided based on a temperature difference between the reference temperature measurement and the heated temperature measurement.

Abstract: A connection clamp assembly and an electrical system including a connection clamp assembly are disclosed. The connection clamp assembly includes a rigid clamp portion with one or more protrusions configured to mechanically secure one or more electrical leads of an electronic device to one or more electrical connection points on a printed circuit board assembly forming an electrical connection. One or more fasteners pass through the rigid clamp portion and are configured to couple the connection clamp assembly to the printed circuit board assembly. A lid elastic element is received by the rigid clamp portion and is configured to elastically press on the electronic device, mechanically and thermally coupling the electronic device to the printed circuit board assembly.

Abstract: Heat transfer systems and methods are disclosed. A heat transfer system includes an electronic enclosure housing at least one electronic component and including a volume for a first fluid. A sealed cavity is disposed within the electronic enclosure and contains within itself a second fluid that is physically separated from the first fluid. A heat transfer device has a first surface configured to directly interface with the first fluid and a second surface configured to directly interface with the second fluid.

Abstract: An applicator for roll roofing materials employs a frame with a support bar removably engaged on the frame. The support bar receives a roofing material roll. An application roller is supported from the frame in trailing engagement with a roofing surface. A take-up roller is supported by the frame onto which tear sheet from the roofing material roll is rolled. Wheels are attached to the frame and a drive system provides a drive pulley attached to a wheel, a driven pulley operationally attached to the take-up roller, and, a drive belt extending from the drive pulley to the driven pulley. The drive system is adapted for slippage upon the rolled tear sheet reaching a predetermined diameter.

Abstract: A golf cart is provided with an adjustable golf bag hoop. The hoop is provided with a rod and a cam-locked collar. The collar is moveable along the length of the rod to adjust to varying heights of golf bags.

Abstract: A golf cart vehicle is disclosed having a suspension that includes a single suspension device that provides for a plurality of functions. In one embodiment the single suspension device includes a plurality of transverse mounted leaf springs that are longitudinally spaced apart from one another to provide a spring and control arm combined effect. The leaf springs can be coupled to a wheel, such as through a steering knuckle via a ball and socket joint. The leaf springs can further be mounted to a chassis via clamps. In one embodiment the clamps are connected to the leaf springs through resilient bushings which can be spaced apart from one another to provide an anti-roll bar effect.

Abstract: A power train for a vehicle includes a gearbox with an input shaft and an output shaft and is configured such that the input shaft drives the output shaft at a single speed ratio in a first direction and a single speed ratio in a second direction. The output shaft is coupleable with the front and rear vehicle axles to separately drive each axle. Further, a continuously variable transmission is connected with an engine shaft and with the gearbox input shaft such that the engine shaft drives the input shaft within a range of speed ratios from less than 1 to greater than 3. Front and rear differentials are coupled with each axle and with the output shaft and drive the axles at different speed ratios such that a base surface drives the front axle independently of the front differential when at least one rear wheel rolls upon the surface.
