As used herein, the words “couple”, “couples”, “coupled” or “coupling”, refer to connecting, either directly or indirectly, and does not necessarily imply a mechanical connection.

As used herein, to “de-ice” is to remove snow, ice, or frost from a surface. De-icing may involve mechanical action, heating, the use of chemicals, or combinations thereof. A tool or chemical that assists in the de-icing process may be referred to as a “de-icer”.

As used herein, “front” indicates the side of an object that is closest to a forward direction of travel under normal use of the object or the side or part of an object that normally presents itself to view or that is normally used first. “Rear” or “back” refers to the side that is opposite the front.

As used in this disclosure, a “grip” is a covering that is placed over a hand hold, handle, shaft, or other object.

As used in this disclosure, a “handle” is an object by which a tool, object, or door is held or manipulated with the hand.

As used in this disclosure, a “hinge” is a device that permits the turning, rotating, or pivoting of a first object relative to a second object.

As used in this disclosure, a “housing” is a rigid casing that encloses and protects one or more devices.

As used herein, the words “invert”, “inverted”, or “inversion” refer to an object that has been turned inside out or upside down or to the act of turning an object inside out or upside down.

As used in this disclosure, the word “lateral” refers to the sides of an object or movement towards a side. Lateral directions are generally perpendicular to longitudinal directions. “Laterally” refers to movement in a lateral direction.

As used in this disclosure, an “LED” is an acronym for a light emitting diode. An LED allows current to flow in one direction and when current is flowing the LED emits photons. The wavelength of the light that is emitted may be in the visible range of the spectrum or may extend into either the infrared (IR) spectral range or the ultraviolet (UV) spectral range. The brightness of the LED can be increased and decreased by controlling the amount of current flowing through the LED. Multiple LEDs having different emission spectrums may be packaged into a single device to produce a multi-color LED. A broad range of colors may be produced by multi-color LEDs by selecting which of the multiple LEDs are energized and by controlling the brightness of each of the multiple LEDs. Organic LEDs (OLEDs) are included in this definition.

As used in this disclosure, a “lens” is a transparent substance through which light can pass. A lens may or may not be formed with curved surfaces that are used to concentrate or disperse the light that travels through the lens.

As used herein, the word “longitudinal” or “longitudinally” refers to a lengthwise or longest direction.

As used in this disclosure, a “manifold” is a pipe or chamber having several ports through which liquid or gas is gathered or distributed.

As used in this disclosure, a “reservoir” refers to a container or containment system that is configured to store a liquid.

As used herein, the word “sacrificial” refers to a first object that is intended to be eroded or otherwise destroyed in order to protect a second object from being damaged. As a non-limiting example, the sacrificial object may be a trim-piece that is provided to protect an object from wear. In some embodiments, the sacrificial object may be periodically replaced to provide an extended period of protection.

As used in this disclosure, a “shovel” is a tool that is used for lifting and moving bulk items such as dirt, snow, or gravel. A shovel can be a hand tool or a mechanical device.

As used in this disclosure, a “spring” is a device that is used to store mechanical energy. This mechanical energy will often be stored by deforming an elastomeric material that is used to make the device, by the application of a torque to a rigid structure, or by a combination thereof. In some embodiments, the rigid structure to which torque is applied may be composed of metal or plastic.

As used in this disclosure, a “tool” is a device, an apparatus, or an instrument that is used to carry out an activity, operation, or procedure.

As used in this disclosure, “transparent” refers to a material that allows light to pass through the material without significant scattering such that an object can be clearly seen through the material.

As used in this disclosure, a “valve” is a device that is used to control the flow of a fluid (gas or liquid) through a pipe or to control the flow of a fluid into and out of a container.

As used in this disclosure, “vertical” refers to a direction that is parallel to the local force of gravity. Unless specifically noted in this disclosure, the vertical direction is always perpendicular to horizontal.

Throughout this document references to “wire”, “wires”, “wired”, or “wiring” may describe and/or show a single conductor when, in fact, two conductors may be required to power or control a subsystem; a convention used herein is to not show the common return conductor to which all electrical subsystems are connected—this common return conductor is a continuous electrical path and does not pass through any type of switch or other electrical component other than the possibility of passing through one or more connectors.
