A chip array structure for laser diodes, formed on an active surface of a semiconductor chip produced from a semiconductor process includes a plurality of light-emitting elements in an array arrangement, at least one insulation wall, at least two wire bond areas and a plurality of connection electrodes. The information signal is transformed to form a transformed information signal using a first transform represented by a polynomial G1 having a degree P. Shirorekha detection criteria may be at least one criterion such as a length of the shirorekha stroke, a horizontality of the shirorekha stroke, a straightness of the shirorekha stroke, a position in time at which the shirorekha stroke is made in relation to one or more other strokes in the handwritten input, and the like. The tools reveal the influence of alternate settings on the system’s behavior, in response to an expected stream of incoming messages, providing users with insights about how control settings affect alerting, filtering, or routing behaviors.
