Abstract: A perforating apparatus and method includes a longitudinal cylinder axis about which a cylinder rotates. At least one shaped anvil bead is disposed on the cylinder. The cylinder including an anvil block and an anvil bead form a cavity. The cavity may be used to control the debris produced during the perforating process. A blade is disposed on a support to cooperate in contacting relationship with the anvil bead. A web is perforated as the web passes between the rotating cylinder and the support and the blade operatively engages with the anvil bead. The debris may be controlled by being drawn into the cavity prior to the point where the blade engages the anvil and, subsequently, being expelled after the point where the blade engages the anvil bead.

Abstract: A bolster-actuated folding knife may have a folding knife blade whose opening and closing is controlled by an actuator on the knife's handle. This bolster-actuator may rotate in either of two rotational directions about the same pivot as the knife blade. When a user rotates the bolster-actuator in one direction, the bolster's pin may impinge via direct contact with the knife blade forcing the knife blade fully open. When a rotates the bolster-actuator in the opposite direction bolster-actuator rotation and thus bolster pin deflection may cause the knife's locking tab to disengage from a cutout in the knife blade, unlocking the knife blade from its fully locked-open position and urging the knife blade to close. Thus, the bolster-actuated folding knife may provide a convenient means to open and close a locking, folding knife with only one hand, and without substantial interference with the knife's aesthetic appeal.

Abstract: Sensor-based shaving systems and methods of analyzing a user's shave event are described for determining a unique threshold value of the user. A grooming device comprises a handle having a connecting structure connected to a hair cutting implement. A shave event sensor associated with the grooming device measures a user behavior, which includes collecting a first dataset comprising shave data defining a shave event. The first dataset is transmitted via a communication device and is analyzed to determine baseline behavior data of the user, and a unique threshold value of the user is determined from the baseline behavior data. One or more subsequent datasets, each comprising shave data of one or more corresponding shave events, is compared to the unique threshold value to determine comparison data. An indication is provided, based on the comparison data, to indicate a deviation from the threshold value and to influence the user behavior.
