Furniture such as a cot, table, or chair is provided that uses shock-corded poles in combination with one or many torsion spring mechanisms to achieve a compact pack size. Alternatively, central hubs may be used in lieu of the spring mechanisms. The furniture maintains its usefulness by assembling to a size comparable with conventional full-sized furniture. One or many torsion springs associated with the furniture allow a user to easily achieve tension over desired elements of the furniture while reducing user exertion.

A battery life extender for a portable lighting device employs a reconfigurable mechanism operable to selectively electrically isolate one or more batteries from a circuit having a parasitic power drain. For example, a lighting device includes a light generating element, at least one battery, a user operated switch configured to control delivery of electrical power from the at least one battery to the light generating element, and a housing assembly supporting the at least one battery and the light generating element. The user operated switch can impart a parasitic power drain. The housing assembly is reconfigurable to: (a) a first configuration in which the user operated switch is electrically connected to the at least one battery, and (b) a second configuration in which the at least one battery is electrically isolated and the at least one battery is retained by the housing assembly.

Described herein is a lighting system capable of responding to user input provided via proximity sensors. In some embodiments, proximity sensors are communicatively coupled to a processor capable of receiving input from the sensors. The sensors may be arranged in a row such that an object moving down the row proximate to the sensors may trigger each sensor sequentially. In some embodiments, the lighting system may alter a beam configuration or cycle between various lighting modes in response to receiving input from the proximity sensors. In some embodiments, the order in which the sensor input is received may be used to determine which lighting mode to cycle to.
