A signet ring displays a crest or coat of arms.
"coats of arms" are usually granted only to a single person ... and NOT to an entire family or to a particular surname. Coats of arms are inheritable property, and they generally descend to male lineal descendents of the original arms grantee. So, you will know if you inherited a "coat of arms" ... because if you did, you'll already have it! The caveat to this paragraph is that "rules" and traditions regarding Coats of Arms vary from country to country. So, be certain to research the heraldry traditions of your ancestor's home country. The family crest is typically a figure and generally a beast of some kind. It can be found "atop the helmet placed above the shield." Traditionally the crest has been used primarily by men. However, some queens of England or Britain have been treated with crests. In the early history of the family crest, its issuance was usually confined to people of rank, but later the crest was included in nearly every grant of arms.

A crest is a historic term meaning the figure, animal or other item worn on top of a knight's helmet during the late medieval period. This also served as a kind of badge which would appear on his standard (if he were of sufficiently high rank), or on the tunics of his servants and men-at-arms. The crest might also be shown on his seal. It was considered to be a part of the coat-of arms, even though it did not appear on the shield, and was part of the grant of arms awarded to the knight by the college of arms.A logo is an extremely modern badge, shape, sign, word or combination of these used to identify a particular marketing brand. It has very little history and has nothing at all to do with the medieval period; it is entirely related to the retail or marketing industry.

A coat of arms is a kind of logo. Coats of arms were developed long ago, when most people couldn't read, as a means of identifying specific people on the battlefield. They use symbols or combinations of symbols within a defined formal structure to accomplish that. Logos are used to identify companies and other organizations through a symbol or combination of symbols.

Apparently, "Arms" used to indicate that an inn, pub, hotel, etc. has a coat of arms on their sign, to indicate that they had some kind of noble patron. I imagine this is not true of all places with that in the name (especially in America), as they may just be trying to sound fancy.
