Publication number: 20060208938Abstract: Described is a switched capacitor circuit for performing an analog circuit function. Unlike conventional switched capacitor circuits employing operational amplifiers, the switched capacitor circuit uses a comparator and does not require direct feedback between the input and output of the comparator. The switched capacitor circuit includes a first and a second switched capacitance network, a comparator and a current source. The first switched capacitance network has an input terminal to receive a circuit input voltage during a first phase. The comparator has an input terminal in communication with the first switched capacitance network and an output terminal in communication with the second switched capacitance network through a switched terminal. The current source communicates with the switched capacitance networks and supplies a current to charge the networks during a second phase. The circuit can be used, for example, to provide high gain amplification in integrated circuits.Type: ApplicationFiled: January 30, 2006Publication date: September 21, 2006Applicant: Massachusetts Institute of TechnologyInventors: John Fiorenza, Todd Sepke, Hae-Seung Lee, Charles Sodini

Patent number: 6356003Abstract: A motor includes a shaft, at least one bearing, a rotor, a stator, and a brush carrier. The bearing is located adjacent to the shaft. The rotor is interconnected to the shaft and magnetically interacts with the stator. The brush carrier is releasably interconnected to the rotor and/or stator such that the brush carrier can mechanically disconnect from the rotor and/or stator without disturbing a bearing and other motor elements. By disconnecting the brush carrier from an endbell and viewing the commutator surfaces through an endbell aperture, the commutator surfaces of the motor are inspected. Since more than one winding portion of the armature can act as a commutating surface, motor assembly is simplified and the motor has a long useful life. A motor including more than one brush carrier is also provided.Type: GrantFiled: October 12, 1999Date of Patent: March 12, 2002Inventors: John Fiorenza, Allen Jeske, Felix Belkin

Patent number: 5619845Abstract: The improved battery-powered lawnmower includes a safety key that is automatically removed when the removable battery is removed, while at the same time blocking the battery recharger receptacle. The lawnmower also includes a control circuit that shuts off the lawnmower upon the occurrence of one or more of several predetermined conditions, including low battery voltage, the encountering of heavy grass for a period of 3 seconds or more, and high motor current that may occur when the cutting blade is jammed. The cutting blade is designed to move through any debris accumulated between the blade ends and the housing sidewall without sacrificing the lift for needed cutting and mulching. The invention also includes a unique height adjustment assembly for adjusting the height of the chassis, a handle attachment that allows the handle to be positively tightened to the lawnmower chassis, and a telescoping groove for the battery's quick connect/disconnect terminals.Type: GrantFiled: December 6, 1995Date of Patent: April 15, 1997Assignee: Briggs & Stratton CorporationInventors: Patrick J.
