Abstract: An encapsulation block for a digital signal processing (DSP) block. The encapsulation block includes DSP block having an input terminal, an output terminal, and an input clock. The encapsulation block also includes pacing control network operatively connected with the input terminal, the output terminal, and the input clock of the DSP block. The input terminal of the DSP block is configured to receive a samples-in data stream inputted at a predefined clock period defined by the input clock. The output terminal of the DSP block is configured to receive a samples-out data stream outputted at a predefined paced parameter. The pacing control network is configured to control data flow at the samples-in data stream and the samples-out data stream independently of the DSP block.

Abstract: A hybrid polyurethane/polyurea polymer suitable for forming a coating on a structure which is in contact with water includes the reaction product of a polyol component consisting of one or more polyols, a polyamine, and a curing agent, such as a polyisocyanate. The polyol component includes a Novolac-type polyether polyol.

Abstract: The invention is to a stool for use in a swimming pool. The stool has a single leg attached to a seat. A gripper device is placed on the end of the leg to prevent the leg from slipping when it engages the bottom of the pool.

Abstract: In one embodiment, a solid state DC power supply includes an inverter (30) having two half-bridges (32, 34) in which are provided pairs of MOSFETS (Q5-Q12) used as switching elements. An output transformer (60) and a rectifier (85) are connected to output terminals (T60). A feedback path includes switching control means (40) separate primary and secondary drive means (10, 20) supplying drive pulses to the switching means (Q5-Q12) in the inverter (30). The secondary drive means (12, 13) amplifies the pulse output of the primary drive means (11) in order to improve the switching speed of the inverter (30). Current detection is provided by a transformer (70) connected to switching (40). The primary and secondary drive means receive pulses from a pulse width modulator (IC5) the output of which is isolated by transformers (TX1, TX2). In a modification, a power converter in the form of a DC power supply includes parallel MOSFET (M) and IGBT (I) switch pairs in each arm of a full wave bridge configuration.
