摘要:
A printing system comprising: a printing device having first and second similar printing mechanisms; first and second similar holding means for holding respective first and second rolls of label stock in a position to pass the first and second printing mechanisms respectively; and a local processor connected to supply print data to a selected one of said first and second printing mechanisms and comprising means for receiving print data and a command for supplying said print data to the selected one of said first and second printing mechanisms to print an image on a label of the respective associated one of said first and second rolls of label stock, based on said command; and a host computer connected to the printing system and arranged to execute a common printer driver for supplying said print data and command to the printing device, regardless of which printing mechanism is selected.
摘要:
A method and system for securely recording a verbal transaction, the method including the steps of recording an offer and an acceptance of the transaction as a digital audio file, generating a voice security token from the recorded digital audio file, and providing the generated voice security token to a buyer and/or a seller, wherein the voice security token provides authentication of the transaction. The voice security token is generated by sampling audio frequency and intensity set of the recorded digital audio file and converting the sampled information from a current time domain spectrum to a frequency domain spectrum to condense the sampled information. Finally, a digital file is generated from the condensed information, and encrypted to produce the voice security token.
摘要:
A method and system for determining whether a first one of a plurality of labels on a roll of label stock is a full label. The method includes sensing a leading edge of the roll of label stock, sensing a location of a first one of a plurality of indicator marks that are printed on the back side of the roll of label stock, sensing a location of a second one of the plurality of indicator marks, sensing a location of one of a plurality of top of form marks that are printed on the back side of the roll of label stock. The method further includes determining whether the first one of the plurality of labels is a full label based on the leading edge of the roll of label stock, the location of the first one of the plurality of indicator marks, the location of the second one of the plurality of indicator marks, and the location of the one of the plurality of top of form marks.

This invention relates to a spool for a supply of printing material, said spool comprising a first part, said first part comprising a shaft on which the supply of printing material is mountable, a second part, said second part having an opening and being arranged to retain a supply of printing material on the first part, said opening being arranged to engage said shaft, wherein one of said opening and the shaft is resilient and the other of the opening and the shaft has at least one part which extends towards the said one of said opening and the shaft more than at least one other part thereof to thereby cause said opening to engage with said shaft.
摘要:
An IP telephony gateway and a user interface resource enable a subscriber to place an outgoing call according to the voice over IP (H.323) protocol to a destination party from a user interface session of an intelligent dial tone service such as voice activated dialing, and resume the user interface session upon completion of the outgoing call with the destination party. The IP telephony gateway establishes a user interface session for the subscriber with the user interface resource across a first Real Time Protocol (RTP) data stream. The user interface resource initiates a second RTP data stream to a destination party in response to reception of a prescribed command from the subscriber. Although an RTP bridge connecting the first and second RTP data streams can be maintained by the user interface resource, the user interface resource may also use the Empty Capability Set feature in the H.323 standard to cause the IP telephony gateway to close the first and second RTP data streams to the user interface resource. The user interface resource then issues Non-Empty Capability Set messages to the IP telephony gateway for the first and second RTP data streams, causing the IP telephony gateway to internally bridge the first and second RTP data streams. The user interface resource monitors connections between the subscriber and the destination party, and upon detecting a disconnect by the destination party causes the IP telephony gateway to resume the user interface session, by repeating the sequence of sending Empty Capability Set and Non-Empty Capability Set messages to the IP telephony gateway to break down the bridge and re-establish the connection between the subscriber and the user interface resource.

Piano keyboard cards contain a pictured keyboard on the cards with note indicators on keys to be played and fingering numbers showing the finger to be played. These piano keyboard cards have several varieties including scale and chord keyboard cards. These piano keyboard cards can be used on their own without a piano. Also included is a music notation sheet that has all notes of music notation labeled and a fully labeled piano sheet that has all the notes on a piano labeled. Used in conjunction these sheets' line up together clarifying where each key of the piano is on a musical scale. Also included is a fully combined version of the music notation and piano sheets.

A spool for a supply of printing material includes a first part having a shaft on which the supply of printing material is mountable, and a second part having an opening and being arranged to retain the supply of printing material mounted on the first part. The opening is arranged to engage the shaft. One or the other of the opening and the shaft is resilient and the other of the opening and the shaft has at least one part which extends towards the said one of said opening and the shaft more than at least one other part thereof to thereby cause the second part having the opening to engage with the shaft.
