Abstract: A frequency limitation method used in quasi-resonant control of a switching regulator is disclosed. The switching frequency is limited through setting a minimum time limit, such as a minimum switching period or a minimum OFF time. The minimum time limit may be a first time limit or a second time limit. The minimum time limit is changed into another value if the minimum voltage point approaches the minimum time limit point, so as to eliminate the audible noise.

Abstract: A shredder is disclosed having a jam proof system. In one embodiment, the jam proof system provides a thickness detector having a contact member which displaces as an article is inserted into a throat of the shredder and a resistance generating mechanism configured to provide a resistance force to the contact member, in response to displacement of the contact member. The greater the thickness of the material the greater the resistance force that will be realized. When the material reaches a predetermined thickness, there will be a significant change in the resistance force. The resistance generating mechanism may include at least two spring mechanisms serially arranged, such as, a first spring mechanism and a second spring mechanism. This feature provides immediate and direct feedback to the user that the article inserted into the shredder may be too thick. In addition, the thickness detector may include a sensor, and in particular, a Hall effect sensor assembly configured to measure the thickness of the article inserted into the throat. The sensor may communicate with a controller that is configured to alert the user, and/or alter the operation of the shredder, in response to the thickness of the material. For example, the controller may visually and/or audibly alert the user, or control the shredder motor response.

Abstract: Hyperbranched polymers are prepared by a process in which a monomer having the form Ax is reacted with another monomer of the form By, where A and B are functional groups that do not react with themselves, but do react with each other. The process allows synthesis of hyperbranched polymers having a single type of terminal functional group from comonomers, each of which has a single type of functional group. The invention allows greater flexibility in the preparation of a larger variety of different hyperbranched polymers and enables hyperbranched polymers to be prepared at a lower cost as compared with conventional processes using monomers having two types of functional groups that react during polymerization.

Abstract: Hyperbranched polycarbosilanes, polycarbosiloxanes, polycarbosilazenes and copolymers thereof are prepared by reacting a difunctional or polyfunctional monomer having functional groups of one type (A) without any other functional groups capable of reacting significantly during polymerization, and a difunctional or polyfunctional monomer having functional groups of another type (B) without any other functional groups capable of reacting significantly during polymerization, wherein each A-functional group is reacted with a B-functional group, and wherein at least one of the monomers has a functionality of at least three. The process enables hyperbranched polycarbosilanes, polycarbosiloxanes, polycarbosilazenes and copolymers thereof to be prepared at a lower cost than with conventional synthesis processes, and provides greater flexibility in the preparation of a larger variety of different types of hyperbranched polycarbosilanes, polycarbosiloxanes, polycarbosilazenes and copolymers thereof.
