Description



TECHNICAL FIELD

[0001] Embodiments are related to viewing windows for electrical, mechanical, and electro-mechanical instruments. Embodiments are also related to techniques, devices, and systems for cleaning such viewing windows.

BACKGROUND

[0002] Many electrical/electronic, mechanical, and/or electromechanical instruments such as gas meters and other measuring systems (e.g., marine systems, samples, etc.) include the use of a transparent viewing window (e.g., glass or other transparent material) to view measurement data. A key problem with such viewing windows is that moisture (e.g., water, fog, etc.) or, for example, dirty oil, located on or at the inside portion of the viewing window obscures the viewing window, which renders difficult viewing of the instrument panel or other data displayed on instrument panels or other display media located below the window.

[0003] Current approaches to cleaning the internal side of the viewing window involve cleaning the window directly with, for example, a mechanism of manual manipulation. This approach, however, is complicated by the limited space available at the window, along with possible fluid leakage, damage to internal instrumentation. The manufacturing costs are also complicated, because of the difficulty in controlling the quality of the instrument during manufacturing to accommodate cleaning of the viewing window. The longtime cleaning performance is therefore not good because the wiper tip typically wears out sometime later, which it makes it difficult if not impossible to achieve gap compensation between the glass and the wiper tip.

[0004] FIG. 1 illustrates a perspective view of a prior art instrument 10 with a viewing window 13 shown within area 12. It can be appreciated that due to the compact nature of the viewing window and its direct mechanical and electrical association with the instrument 10, cleaning the internal side of the viewing window 13 presents difficulties. One solution is simply to remove the face portion 15 which maintains the viewing window 13. To do so, however, will likely result in damage to the instrument 13 and its sensitive internal components. Adding cleaning fluid can also damage the instrument 13. A typical approach involves pushing and pulling the outside handle by hand so that the connected wiper inside the window cleans the glass. This cleaning approach, however, is complicated because of the presence of the instruments seal system.

[0017] The embodiments will now be described more fully hereinafter with reference to the accompanying drawings, in which illustrative embodiments of the invention are shown. The embodiments disclosed herein can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the embodiments to those skilled in the art. Like numbers refer to like elements throughout. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

[0018] FIG. 2 illustrates a side view of an instrument 20 having a viewing window 29 with a magnet wiper 25, in accordance with a preferred embodiment. The magnet wiper 25 is composed of a group of magnets including internal/inside magnets 22, 24 and external/outside magnets 26, 28. The viewing window 29, the internal/inside magnets 22, 24, and the external/outside magnets 26, 28 are located generally within an instrument block 30. Although not a limiting feature of the disclosed embodiments, it can be appreciated that the instrument 30 can be, for example, an instrument such as a gas meter or other electronic/mechanical device with a display providing instrument readings. In the case of instrument 20, the display is located beneath or below the internal side of the view window 29. The viewing window 29 may be composed of, for example, glass or another transparent material.

[0019] FIG. 3 illustrates a top view of the magnet wiper 25 shown in FIG. 2, in accordance with a preferred embodiment. In FIG. 3, only the external/outside magnets 26, 28 are shown.

Conversely, as the inside magnets 22, 24 are moved, the respective outside magnets 26, 28 move accordingly due to the magnetic force thereof between the outside and inside magnets (assuming appropriate positive and negative magnetic force implementations).

[0023] In some embodiments, the wiping medium can be located adjacent to the internal surface. In another embodiment, the wiping medium can be located between the internal surface and the inside magnets. In still another embodiment, the wiping medium removes moisture from the internal surface of the instrument window. In another embodiment, the wiping medium removes moisture from the internal surface of the instrument window 29 in response to manipulation of the wiping medium by the plurality of magnets. In yet another embodiment, the wiping medium can be located adjacent to the internal surface and between the internal surface and the inside magnets 22, 24.

[0024] In another embodiment, a magnet wiper 25 for an instrument window 29 can be implemented, which includes a plurality of magnets comprising inside magnets 22, 24 located adjacent to an internal surface of an instrument window 29 and outside magnets 26, 28 located adjacent to an external surface of the instrument window 29, such that as the outside magnets 26, 28 are moved, the inside magnets 22, 24 move accordingly with respect to the outside magnets 26, 28 via a magnetic force thereof to manipulate a wiping medium and indirectly clean the internal surface of the instrument window 29. Conversely, as the inside magnets 22, 24 are moved, the respective outside magnets 26, 28 move accordingly due to the magnetic force thereof between the outside and inside magnets (assuming appropriate positive and negative magnetic force implementations).

[0025] In yet another embodiment, a method of configuring a magnet wiper 25 for an instrument window 29 can be implemented.
