Publication number: 20180178804Abstract: A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. A controller controls the shift actuator utilizing an actuating pulse and an opposing pulse.Type: ApplicationFiled: July 28, 2017Publication date: June 28, 2018Inventors: Sujay Kawale, Thomas Connolly, Justin Keith Griffiths, Joseph Paul Furner, Sipei Chen, Jeff Hawarden, Yeidei Wang, Adam Christopher Maurer, Carl Christopher Smith, Ian Daniel McKenzie, Ryan Pauls, William A.

A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing includes a single external power access for the shift actuator. A controller interprets controls the shift actuator with actuating and opposing pulses, and interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.Type: ApplicationFiled: July 28, 2017Publication date: June 28, 2018Inventors: Sujay Kawale, Thomas Connolly, Justin Keith Griffiths, Joseph Paul Furner, Sipei Chen, Jeff Hawarden, Yeidei Wang, Adam Christopher Maurer, Carl Christopher Smith, Ian Daniel McKenzie, Ryan Pauls, William A.

Patent number: 8967085Abstract: An electronic pet gate. The electronic pet gate includes a gate transmitter generating a barrier field and a gate receiver generating a deterrent stimulus in the presence of the barrier field. The gate transmitter includes a loop antenna in a low profile elongated sill and a barrier signal generator. The loop antenna transmits the barrier signal and has an elongated geometric shape configured to shape the radiated electromagnetic field into a truncated ellipsoid. The truncated ellipsoidal barrier field has significant field strength along the length of the low profile sill and minimal field strength along the sides of the low profile sill. The low profile sill is designed to securely rest on the floor to block access to an area restricted to a pet without being a substantial physical impediment or hazard to people passing over low profile sill.Type: GrantFiled: March 15, 2013Date of Patent: March 3, 2015Assignee: Radio Systems CorporationInventors: Greg Gillis, Scott MacFarland, Keith Griffith

Patent number: 8934957Abstract: A non-invasive sensor has a contact membrane (6,16) and a cover membrane (2,12), the cover membrane being adapted for extension of a body surface to project the contact membrane against a body surface beneath it. The contact membrane will normally be attached to the cover membrane around its periphery such that at least one of the membranes forms a convex outer surface, and a spacing material (8,20) can be interposed between the membranes to achieve this object. The cover membrane may extend over a support element (10), with the contact membrane overlaying and spaced from the other face of the support element by spacing material.Type: GrantFiled: September 29, 2006Date of Patent: January 13, 2015Inventors: Tilak Kithsiri Dias, Paul Charles William Beatty, William Hurley, Kimberley Mitcham, Adrian Keith Griffiths, Rajcoomar Baboo Ramgulam

Patent number: 8069823Abstract: Described is a vibration stimulus delivery device for delivering a vibration stimulus to an animal and for maximizing the robustness and intensity of the vibration stimulus. The vibration stimulus delivery device is carried by the animal and includes a housing and a vibration probe. The vibration probe is positioned in direct contact with the skin of the animal and generates a vibration, which, when delivered to the animal, is the vibration stimulus. The vibration probe is coupled to the housing such that the coupling minimizes the inherent vibration dampening effect caused by the weight and mass of the housing. The result is a vibration stimulus delivery device that delivers a more robust and intense vibration stimulus to the animal.Type: GrantFiled: January 21, 2008Date of Patent: December 6, 2011Assignee: Radio Systems CorporationInventors: Christopher E. Mainini, Keith Griffith

Publication number: 20080156277Abstract: Described is a vibration stimulus delivery device for delivering a vibration stimulus to an animal by way of a vibration probe secured in physical contact with the skin of the animal. The vibration stimulus delivery device includes a vibration probe, a stimulus trigger detection device, and a carrying device. The vibration probe and the stimulus trigger detection device are secured to the carrying device, which is secured to the animal such that the animal carries the vibration probe and the stimulus trigger detection device. The vibration probe is disposed on the carrying device such that the vibration probe is secured in physical contact with the skin of the animal. The stimulus trigger detection device is adapted to detect an undesirable behavior and is in electrical communication with the vibration probe such that when the stimulus trigger detection device detects the undesirable behavior, the vibration probe is activated. When activated, the vibration probe generates a vibration.Type: ApplicationFiled: January 3, 2007Publication date: July 3, 2008Applicant: Radio Systems CorporationInventors: Christopher E.

Patent number: 5857430Abstract: Apparatus (10) for attaching an object (O) to a sidewall (S) of an aquarium (A). A magnet (18) is attached to an object to be placed inside the aquarium. A niche or pocket (14) is formed in the side (16) of the object which will abut the inside wall of the aquarium. The niche or pocket is sufficiently large to accommodate the magnet which is affixed in place by any suitable means. A second magnet (24) is positioned on the outside of the wall adjacent the object. The magnetic attraction between the two magnets serves to hold the object in place, even if the object is positioned below the waterline (L) in the aquarium.Type: GrantFiled: March 3, 1997Date of Patent: January 12, 1999Inventor: Gerald Keith Griffiths
