Abstract: A vehicle includes a body having a front side, rear side, left side, and right side, and a cab that is movably coupled with the body. The cab includes a front end, a rear end, a left end, and a right end. The vehicle includes an actuator that is operably coupled with the cab and may move the cab between a first position and a second position. Moving the cab from the first position toward the second position moves the cab away from the right side of the body, and moving the cab from the second position toward the first position moves the cab toward the right side of the body.

Abstract: Various implementations include audio systems and methods for mixed rendering to enhance audio output. Certain implementations include an audio system having: at least one far-field speaker configured to output a first portion of an audio signal; and a pair of non-occluding near-field speakers configured to output a second portion of the audio signal in synchrony with the output of the first portion of the audio signal, where the second portion of the audio signal increases intelligibility of the speech content within the audio signal.

Abstract: Heat pumps and thermal exchange systems including heat pumps are provided including heat pumps with a three-way reversible valve for selectively transferring thermal transfer fluid between a heating apparatus/process and/or a cooling apparatus/process. In certain embodiments, the heat pumps and thermal exchange systems include a controller for automatically adjusting the flow of thermal transfer fluid through the three-way reversible valve depending on whether a heating apparatus is present, whether a cooling apparatus is present, and depending on the desired thermal energy exchange characteristics.

Abstract: A mobile device establishes a secure channel protected via encryption with a computing system. The mobile device receives, from the computing system via the secure channel, encrypted Wi-Fi authentication credentials for a Wi-Fi access point that is associated with the mobile device and that implements a network. The mobile device decrypts the encrypted Wi-Fi authentication credentials to generate decrypted Wi-Fi authentication credentials. The mobile device generates, based on the decrypted Wi-Fi authentication credentials, network information to enable the mobile device to authenticate to the Wi-Fi access point without user input and thereby connect to the network.

Abstract: A waveguide assembly for delivering focused acoustic energy includes a housing comprising a chamber filled with a medium for propagating acoustic waves. An acoustic transducer is supported the housing and has a surface facing into the chamber. The surface is configured to transmit acoustic waves into the chamber through the medium toward a focus zone. The waveguide assembly also includes structure configured to focus the acoustic waves transmitted from the surface of the acoustic transducer. The waveguide assembly further includes a flexible elongated waveguide having a first end positioned in the chamber opposite the curved surface, and a second end outside the chamber. The waveguide has a tubular configuration with an inner lumen in fluid communication with the chamber via the first end and being filled with the medium. The first end of the waveguide is configured to be positioned in the focus zone so that the focused acoustic waves are propagated through the medium in the inner lumen of the waveguide.

Abstract: A system and method for determining location information of a portable device relative to an object is provided. In one embodiment, a booking control system is provided for booking a resource or service associated with the object. The system and method may determine location information with respect to the portable device, and identify the user as checked-in or checked-out (e.g., the resource is in-use or out of use) based on the location information.

Abstract: A mobile application is disclosed for providing a flight planning tool on a client device. The mobile application may include a data input module configured to receive, via interface hardware on the client device, a selection of one of a plurality of selectable tools. The mobile application may further include a graphics module configured to display, via the interface hardware, a user interface associated with the selection. The mobile application may further include a flight planning communication module configured transmit a request for information associated with the selection, via an API, to a flight planning system, and receive, from the flight planning system via the API, responsive information that fulfills the request, wherein the responsive information was generated by the flight planning system based on information from a third-party device.

Abstract: An adjustable bladeset for a hair clipper with a clipper housing includes a stationary blade having a stationary toothed end with a plurality of stationary teeth, an opposite stationary base end and an upper surface, and a moving blade having a moving toothed end with a plurality of moving teeth, the moving blade configured for reciprocal transverse movement relative to the stationary blade on the upper surface. The stationary blade is linearly displaceable relative to the moving blade by action of an adjustment lever on the clipper housing. A blade guide is on the upper surface at the stationary base end, and has at least one toothed strip. The adjustment lever is connected to a blade actuator shaft having at least one toothed cog configured to engage the toothed strip so that rotation of the actuator shaft causes the linear displacement of the stationary blade relative to the moving blade.

Abstract: An arthropod trapping device having a housing including a base and a shade coupled to the base. The base includes a convex outward-facing wall and an opposing rear-facing wall, electrically conductive prongs, a circuit board, and a first and second LED electrically connected to the circuit board. The shade includes an outward-facing surface and a LED-facing surface. A first end region of the shade is adjacent to the outward-facing wall of the base such that the first end region of the shade overlaps at least a portion of the outward-facing wall of the base. The LED-facing surface that overlaps the base is spaced apart from the outward-facing wall of the base such that an opening is defined between the LED-facing surface of the shade and the outward-facing wall of the base. The opening extends from a first side edge of the base to a second side edge of the base.
