As a non-limiting example, the upper end of a vertical shaft is the top end of the vertical shaft.
Throughout this document the terms “battery”, “battery pack”, and “batteries” may be used interchangeably to refer to one or more wet or dry cells or batteries of cells in which chemical energy is converted into electricity and used as a source of DC power. References to recharging or replacing batteries may refer to recharging or replacing individual cells, individual batteries of cells, or a package of multiple battery cells as is appropriate for any given battery technology that may be used. The battery may require electrical contacts which may not be illustrated in the figures.
As used herein, the words “control” or “controls” are intended to include any device which can cause the completion or interruption of an electrical circuit; non-limiting examples of controls include toggle switches, rocker switches, push button switches, rotary switches, electromechanical relays, solid state relays, touch sensitive interfaces and combinations thereof whether they are normally open, normally closed, momentary contact, latching contact, single pole, multi-pole, single throw, or multi-throw.
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 in this disclosure, a “cylinder” is a geometric structure defined by two identical flat and parallel ends, also commonly referred to as bases, which are circular in shape and connected with a single curved surface which may be referred to as the face. The axis of the cylinder is formed by the straight line that connects the center of each of the two identical flat and parallel ends of the cylinder. Unless otherwise stated within this disclosure, the term cylinder specifically indicates a right cylinder which is defined as a cylinder wherein the curved surface perpendicularly intersects with the two identical flat and parallel ends.
As used in this disclosure, the terms “distal” and “proximal” may be used to describe relative positions. Distal refers to the object, or the end of an object, that is situated away from the point of origin, point of reference, or point of attachment. Proximal refers to the object, or end of an object, that is situated towards the point of origin, point of reference, or point of attachment. Distal implies ‘farther away from’ and proximal implies ‘closer to’. In some instances, the point of attachment may be the where an operator or user of the object makes contact with the object. In some instances, the point of origin or point of reference may be a center point, a central axis, or a centerline of an object and the direction of comparison may be in a radial or lateral direction.
As used in this disclosure, “flexible” refers to an object or material which will deform when a force is applied to it, which will not return to its original shape when the deforming force is removed, and which may not retain the deformed shape caused by the deforming force.
As used in this disclosure, a “heating element” is a resistive wire that is used to convert electrical energy into heat. As non-limiting examples, common metals used to form heating elements include a combination of nickel and chromium, a combination of iron, chromium and aluminum, a combination of copper, nickel, iron, and manganese, or platinum.
As used in this disclosure, a “patient” is a person who is designated to receive a medical treatment, therapy or service.
The term patient may be extended to an animal when used within the context of the animal receiving veterinary treatment or services
As used in this disclosure, a “plug” is an electrical termination that electrically connects a first electrical circuit to a second electrical circuit or a source of electricity.
As used in this disclosure, “resilient” or “semi-rigid” refer to an object or material which will deform when a force is applied to it and which will return to its original shape when the deforming force is removed.
As used herein, “resistance wire” refers to wire intended for use as an electrical resistor. Resistance wire generally has a higher resistivity than other conductors such as copper and aluminum so that a shorter length of wire can be used to construct a higher value resistance. Resistance wire may also be selected for its temperature coefficient of resistivity, oxidation characteristics, solderability, or combination thereof. Resistance wire is often used for heating elements. Non-limiting examples of resistance wire include nichrome wire (a nickel/chromium alloy), iron-chromium-aluminum alloys, constantan (a copper/nickel alloy), and nickel/iron alloys.
As used herein, “rigid” refers to an object or material which is inflexible. If a force is applied to a rigid object the rigid object does not bend or deform unless the force applied reaches the breaking point of the rigid object.
As used in this disclosure, a “slot” is a long narrow groove, cut, opening, or aperture that is formed in or through an object.
As used herein, “snap-on clip” or “snap-on pipe clip” refers to a fastener that comprises a section of a cylinder made from a semi-rigid material with a longitudinal gap of less than half of the cylinder. In some implementations, the edges of the gap may curve outward away from the center of the cylinder. The snap-on clip may be attached to a section of pipe by aligning the clip and the pipe longitudinally with the pipe against the gap and by pressing the clip onto the pipe. As it is pressed onto the pipe, the edges of the clip may spread apart to allow the pipe to pass through the gap. Once the pipe has passed through the gap, the edges may spring back to their original positions such that the clip encircles the pipe and is retained on the pipe. The clip may be removed from the pipe by prying the clip off such that the pipe passes through the gap in the opposite direction.
As used in this disclosure, a “spool” is a cylindrical device upon which a flexible material, including but not limited to a rope, a cable, a yarn, a cord, a sheet of fabric, or a tape, can be wound. Depending on context, a spool may also comprise the flexible material stored upon the spool.
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 herein, “water repellent” refers to the hydrophobic characteristic of an object. Water does not easily penetrate a water repellent object. The water repellent characteristic may be intrinsic to the type of material that the object is made of or it may be the result of a coating applied to the object.
With respect to the above description, it is to be realized that the optimum dimensional relationship for the various components of the invention described above and in
