Abstract: A cutting guide may have a protruding seam locking feature (or features) to facilitate the consistent cutting of a material with a desired shape or pattern. A seam locking feature protrudes from a bottom surface of the cutting guide to form a locking edge against which a seam can be aligned while the material is cut. A seam locking feature may be formed of a non-slip material to restrict movement of the cutting guide during cutting. A seam locking feature (or features) may have a variety of shapes or configurations to facilitate the cutting of material with a corresponding variety of shapes or patterns.

Abstract: A meeting negotiation system provides a new approach to scheduling events by negotiating schedules while preserving privacy through a shared representation that separates the meeting negotiation from the meeting invitation. The negotiation system integrates all scheduling-related information such as times users can meet, location, etc. and reduces dependency on designations of time as free or busy by a potential meeting attendee. Consequently, the negotiation system enables time preferences richer than just free or busy, allowing potential meeting attendees to designate preference in addition to time available. The negotiation system supports annotations and comments as a discussion mechanism, giving feedback to the meeting scheduler before the meeting invitation is issued. Possible times provided for the meeting are provided in the form of a bounded negotiation; participants may select the best time for them to attend a meeting from the bounded negotiation.
