Patent number: 10173272Abstract: A router includes a housing and a motor assembly disposed within the housing. The motor assembly includes a driven shaft having a cavity on a first end of the driven shaft. The router includes a collet that is configured to mate into the cavity of the driven shaft with the collet being configured to grip a shank of a router bit. The router includes a gear mechanism that is configured to couple and decouple from a second end of the driven shaft such that a rotation of the gear mechanism when the gear mechanism is coupled to the second end of the driven shaft causes at least one of tightening and loosening of the collet.Type: GrantFiled: April 9, 2018Date of Patent: January 8, 2019Assignee: Black & Decker Inc.Inventors: Warren A. Ceroll, Craig Schell, Steven D. McDaniel, Gregory Griffin

Publication number: 20170212080Abstract: The present disclosure is directed to an integrated electrostatic sensor for an engine. The sensor includes an outer housing having a body with a first end and a second end. The first end is configured for securing the sensor to the engine and includes a sensing face. The sensor also includes an electrode configured within the housing adjacent to the sensing face and an amplifier configured with the electrode. The electrode contains a plurality of electrons configured to move as charged particles flow past the sensing face. Thus, the amplifier is configured to detect a particulate level as a function of the electron movement. The electrostatic sensor also includes a circuit board configured within the housing and electrically coupled to the amplifier. As such, the circuit board is configured to send one or more signals to a controller of the engine indicative of the particulate level.Type: ApplicationFiled: January 27, 2016Publication date: July 27, 2017Inventors: John David Weickert, Gregory Griffin, James R.

Patent number: 9651469Abstract: The present disclosure is directed to an integrated multi-chip module (MCM) sensor assembly having at least one electrostatic sensor and a circuit board. The electrostatic sensor includes an outer housing with an electrode and an amplifier configured therein. The electrode includes a first end and a second end separated by a predetermined length. The second end includes a sensing face that is substantially flush with an edge of the outer housing. Further, the electrode contains a plurality of electrons configured to respond to one or more charged particles that flow past the sensing face by moving either towards or away from the second end. Thus, the amplifier is electrically coupled to the electrode so as to detect a particle level flowing past the sensing face as a function of the electron movement. Moreover, the circuit board is configured within the outer housing and is electrically coupled to the sensor.Type: GrantFiled: December 12, 2016Date of Patent: May 16, 2017Assignee: General Electric CompanyInventors: John David Weickert, Andrew Scott Kessie, Philip T.

Patent number: 9248815Abstract: A method for automatically decelerating a vehicle having a first side with a first front wheel brake and a first rear wheel brake and second side with a second front wheel brake and a second rear wheel brake, and in which the vehicle further has a braking system with a pump operable to deliver a flow of pressurized hydraulic fluid to the first and second front wheel brakes and to the first and second rear wheel brakes, includes receiving a signal associated with an emergency braking event. The method further includes increasing the hydraulic pressure at the first and second front wheel brakes at a greater rate than at the first and second rear wheel brakes. The method also includes directing hydraulic fluid from the first front wheel brake to the second rear wheel brake upon achieving a targeted level of deceleration or wheel slip.Type: GrantFiled: March 15, 2013Date of Patent: February 2, 2016Assignee: Robert Bosch GmbHInventors: Gregory Griffin, Daniel Kwiatkowski, Joseph Miller

Publication number: 20050179212Abstract: A gasket (201) includes one or more elastomeric sections (301, 305, 307) disposed on a metal substrate (303). An elastomeric ring (307) has an inner diameter (309) that is smaller than an outer diameter of a fastener (205). When the fastener (205) is inserted into the ring (307), the fastener (205) and gasket (201) are retained to each other. When a flange (101) for a device, such as an oil pick-up tube (100), is disposed between the fastener (205) and the gasket (201), the gasket (201) and fastener (205) are retained to the flange (101).Type: ApplicationFiled: February 12, 2004Publication date: August 18, 2005Inventors: Gregory Griffin, Craig Knauf
