Abstract: A process for the preparation of particulate acylated biopolymer comprising anhydroglucose units that comprises several steps. First, dispersing an amount of particulate non-surface modified biopolymer comprising anhydroglucose units in an amount of a liquid alkenyl carboxylatein order to form a first dispersion. Then, adding a catalytic composition to the first dispersion such a to form a second dispersion, heating the second dispersion to a temperature above ambient temperature, and cooling the second dispersion to ambient temperature. Thereafter, the obtained particulate acylated biopolymer is isolated. The amount of a liquid alkenyl carboxylate corresponds to a molar excess of alkenyl carboxylate, the molar excess being defined with respect to the moles of anhydroglucose units comprised in the amount of the particulate non-surface modified biopolymer. The catalytic composition comprises an amount of one, or two or more, non-nucleophilic bases.

The at least one processing device is configured to monitor the viewing direction of the user based on the output of the at least one sensor; determine, based on the monitored viewing direction, whether the user is looking in the direction of the at least one individual; and establish the communication path between the user and the at least one individual if the user is determined to be looking in the direction of the at least one individual.

Abstract: A moldable collar stay device for a shirt turnover collar comprising a collar stay body and dual collar stay inserts. The shape and the length of the present device may be adjusted by fasteners which facilitate changes to the angle of the collar stay inserts and the length of the collar stay body. The device also may be shaped to accentuate the shape of a user's face. Each collar stay insert may be placed inside collar stay pockets at opposite corners of the shirt collar while the stay body lies along the exterior bounds shirt collar. The shirt wearer may adjust the device around the periphery of the collar to the desired position. Once positioned, the device will remain concealed with the collar and collar stay pockets while maintaining the ability to alter the collar shape, the collar stay length and the angle of the collar stay inserts.
