Abstract: Utility vehicles include ground engaging members, a frame supported by the ground engaging members, a motor supported by the frame operably coupled to the ground engaging members, and a battery configured to provide electrical power to the motor. The battery may be removable and configured to be easily charged by outside power sources such as generators and external batteries. A charger may be configured to receive instructions to charge the battery using a specific charger operating characteristic. The vehicle may also include a variety of accessory ports configured to electrically couple to accessories that use AC or DC power.

Abstract: A thermal component has a shield portion and a heat exchanger portion. The shield portion includes a plurality of cells adapted to inhibit radio radiation (RF) having a frequency within a target frequency range, while the heat exchanger portion includes a plurality of elongated channels, each one of the elongated channels being physically connected to and in fluid communication with at least one corresponding cell of the plurality of cells.

Abstract: A fire-resistant gypsum panel comprises: a gypsum core layer comprising set gypsum and a high temperature sag-resistant material including mineral wool in an amount between 0.2% and 3.0% by weight of gypsum.

Abstract: A suspension unit is provided which is removably coupleable to a helmet shell to enhance user safety and helmet functionality. The suspension unit includes: a suspension assembly configured to interface with a suspension attachment scheme of the helmet shell; one or more sensors carried by the suspension assembly and arranged to obtain biometric, environmental, location, motion, impact and/or other data; and a control system carried by the suspension assembly, the control system including at least a power source and a communication module, and being operatively coupled to the one or more sensors to obtain the biometric, environmental, location, motion, impact and/or other data and to transmit, via the communication module, a data signal to a computing device or network based at least in part on said data from which to enhance user safety and helmet functionality.

Abstract: A key assembly including a key support structure, a switch, a base, and a moveable key. A light source, such as an LED, is mounted to the base to provide illumination for backlighting a translucent region disposed in the moveable key. In operation, when pressure is exerted against the moveable key, the moveable key axially translates to operate the switch. When the moveable key is in its at-rest position, light from the light source will be efficiently and uniformly dispersed through the key assembly to backlight the translucent region based on the location of said light source.
