    摘要： A heater operates at a first power to heat a space and a second power to maintain the temperature. The heater uses a first heating element and a second heating element, which are configured to automatically supply the first power during an initial heating period, then step down to the second power for continuous operation. The heater may use a phase chopper circuit and heating element; switched diode and heating element; positive temperature coefficient thermostat, isolated heater, and heating element; latching mechanical timer switch and heating element; and/or a positive temperature coefficient heating element and multi-speed fan to provide dual power levels. The heater may include a first heating element energized during a portion of a heating cycle and a second heating element continuously energized during the heating cycle. The heating cycle is repeated for a period after which both elements are de-energized.

    摘要： Anti-ram systems according to embodiments of the invention comprise at least one bollard section comprising a base of limited height and a plurality of spaced bollards extending upwardly from the base. An anti-ram system according to embodiments of the invention may be erected or installed on a paved surface such as asphalt, concrete, paver stones, etc., or on an unpaved surface such as soil, and need not be partially of fully buried, and yet can qualify for Department of State crash ratings previously assigned to buried bollard systems. Disclosed anti-ram system also comprise a plurality of bollard sections and one or more connectors for interconnecting two or more of the bollard sections, and may also include an anchor or anchor system engaging at least each end of a bollard section not connected to another bollard section. The bollard sections may be filled with ballast and high friction structure may be attached to the bottom of the bollard sections to resist sliding after impact.

    摘要： A method and apparatus is disclosed that uses an arithmetic circuit for adding numbers represented in a redundant form to also subtract numbers received in redundant form, including numbers received from a bypass circuit. A non-propagative comparator circuit is then used to compare a given value with a result from the arithmetic circuit to determine if the result is equal to the given value. All of the operations described above can be accomplished without propagating carry signals throughout the circuitry.The method includes generating a complemented redundant form of at least one number supplied to the arithmetic circuit in redundant form. It also includes providing adjustment input to the arithmetic circuit to augment a result produced through the arithmetic circuit. This adjustment causes the arithmetic circuit to generate a valid outcome in redundant form as a result of a subtraction operation if the arithmetic operation is subtraction. Then the result is compared to a given value using a non-propagative comparator to determine equality or inequality of the result to the given value.
