Patent number: 11967948Abstract: A method and apparatus for use in improving the linearity characteristics of MOSFET devices using an accumulated charge sink (ACS) are disclosed. The method and apparatus are adapted to remove, reduce, or otherwise control accumulated charge in SOI MOSFETs, thereby yielding improvements in FET performance characteristics. In one exemplary embodiment, a circuit having at least one SOI MOSFET is configured to operate in an accumulated charge regime. An accumulated charge sink, operatively coupled to the body of the SOI MOSFET, eliminates, removes or otherwise controls accumulated charge when the FET is operated in the accumulated charge regime, thereby reducing the nonlinearity of the parasitic off-state source-to-drain capacitance of the SOI MOSFET. In RF switch circuits implemented with the improved SOI MOSFET devices, harmonic and intermodulation distortion is reduced by removing or otherwise controlling the accumulated charge when the SOI MOSFET operates in an accumulated charge regime.Type: GrantFiled: June 13, 2022Date of Patent: April 23, 2024Assignee: pSemi CorporationInventors: Christopher N.

Publication number: 20240072604Abstract: An electric motor is provided including a stator, a rotor, a motor spindle coupled to the rotor and extending along a center axis, a first end cap formed on a first side of the stator, a second end cap formed on a second side of the stator and secured to the first end cap to form a first compartment around the stator and the rotor, an electro-magnetic brake module disposed on a side of the second end cap opposite the stator and engaged with the motor spindle, and a motor cover mounted on the second end cap to form a second compartment around the electro-magnetic brake module. The first end cap, the second end cap, and the motor cover form a substantially watertight seal around the stator, the rotor, and the position sensor assembly.Type: ApplicationFiled: August 22, 2023Publication date: February 29, 2024Applicant: BLACK & DECKER INC.Inventors: JOHN B. FOGLE, KEVIN L. PULLEY, MARK J. CLEMENTI, JAMES M. NOBIS, SHAILESH P. WAIKAR, DAVID M. KELLY, NATHANIEL K. BYRNE, TIMOTHY A. CLAPP

Publication number: 20240072599Abstract: An electric power apparatus includes a main planar body having a circular opening that supports a brushless direct-current (BLDC) motor. The motor includes a stator, a rotor, a motor spindle extending through the circular opening, a first end cap formed on a first side of the stator and mounted on the main planar body; and a second end cap formed on a second side of the stator and secured to the first end cap to form a substantially watertight seal around the stator and the rotor. A ratio of a maximum power output of the motor when powered by at least one battery pack to a height of the motor as measured from an upper surface of the main planar body to a top surface of the motor is greater than or equal to approximately 34 watts/mm.Type: ApplicationFiled: August 22, 2023Publication date: February 29, 2024Applicant: BLACK & DECKER INC.Inventors: JOHN B.
