Generating Servo Control Pulses At A Receiver

US Patent:
8049601, Nov 1, 2011
Filed:
Apr 27, 2007
Appl. No.:
11/741357
Inventors:
Richard A. Hofer - Gardner KS, US
Jonathan R. Feldkamp - Gardner KS, US
Assignee:
Castle Creations, Inc. - Olathe KS
International Classification:
G08C 19/12
US Classification:
340 1334, 340 11, 340 132, 340 1333, 701 2, 701 33, 701 36, 701102, 701110, 446 6, 446 31, 446454, 901 6, 901 8, 901 32, 901 36
Abstract:
Systems and methods are provided for controlling one or more servos coupled to a model vehicle. An input signal having a series of input pulses encoded at an input pulse repetition frequency is received at a receiver coupled to a model vehicle having one or more servos. The input signal is decoded at the receiver. A servo control pulse is generated using at least one of the input pulses at the receiver. The servo control pulse is outputted to at least one of the servos at an output pulse repetition frequency that is different from the input pulse repetition frequency.

Novelty Led-Projection Message Balloon

US Patent:
2008024, Oct 2, 2008
Filed:
Mar 6, 2008
Appl. No.:
12/074739
Inventors:
Russell D. Hofer - Saint Louis MO, US
Jonathan Robert Feldkamp - Gardner KS, US
Gary R. Hannah - Shawnee MO, US
Richard Allen Hofer - Gardner KS, US
International Classification:
A63H 27/10
A63H 33/26
F21K 7/00
G09G 3/32
G09F 21/10
US Classification:
446220, 446485, 362 35, 345 82, 34081545
Abstract:
Described herein is a novelty led-projection message balloon for allowing a delightful and novel method of communicating endearing messages and/or animation. The inventive device includes a circuit board, lens assembly, housing, and power source. The circuit board consists of LEDs, a microcontroller, interfacing circuitry, spring brushes, a position detector, and a motor. The power supply provides power to the housed circuit board mounted inside a balloon. The circuit board spins with light emitting elements that are projected via a lens assembly onto the balloon inner wall. The elements are rapidly turned on-off in a sequenced manner to give the illusion of a message or animation (through the persistence of vision) being projected onto the exterior of the balloon.

Mapping Control Inputs To Vehicle-Specific Control Outputs At A Receiver

US Patent:
7831351, Nov 9, 2010
Filed:
Apr 27, 2007
Appl. No.:
11/741342
Inventors:
Richard A. Hofer - Gardner KS, US
Jonathan R. Feldkamp - Gardner KS, US
Assignee:
Castle Creations, Inc. - Olathe KS
International Classification:
G06F 19/00
US Classification:
701 36, 701 33
Abstract:
Systems and methods are provided for processing control inputs at a receiver for one or more servos coupled to a vehicle. A signal containing a plurality of control inputs generated in response to an activation of at least one control element on a transmitter is received at a receiver mounted on a vehicle. The plurality of control inputs is mapped to a vehicle-specific set of servo control signals at the receiver using operations such as reversing, shifting, scaling, delaying, and mixing.

Lawnmowers With Safety Features And Methods Associated Therewith

US Patent:
2021025, Aug 19, 2021
Filed:
Jan 20, 2021
Appl. No.:
17/153249
Inventors:
- Anderson SC, US
Shuai Shao - Simpsonville SC, US
Robert T. Givens - Anderson SC, US
Ayesha Iftiqhar - Greenville SC, US
Jonathan R. Feldkamp - Anderson SC, US
International Classification:
A01D 34/00
A01D 34/68
A01D 34/82
A01D 43/063
Abstract:
A lawnmower comprising: a body; a cutting element coupled with the body; a motor configured to drive the cutting element; a sensor comprising an accelerometer configured to detect an angular displacement of the lawnmower with respect to a vertical axis and a wobble of the cutting element with respect to a horizontal plane; and a processor configured to: compare the detected angular displacement against a tilt threshold value; compare the detected wobble against a wobble threshold value; and control an operational speed of the cutting element when the angular displacement exceeds the tilt threshold value or when the wobble exceeds the wobble threshold value.

Mower Blade And Attachment System

US Patent:
2020025, Aug 13, 2020
Filed:
Feb 10, 2020
Appl. No.:
16/785868
Inventors:
- Anderson SC, US
Jonathan R. Feldkamp - Anderson SC, US
Trent J. Dingman - Franklinville NY, US
Grzegorz Kondro - Piedmont SC, US
Seth H. Chapman - Anderson SC, US
International Classification:
A01D 34/73
Abstract:
A blade for a lawn mower includes a blade body, a longitudinal axis, a center opening, a first aperture, and a second aperture. The blade body has a first end and a second end opposite the first end. The longitudinal axis extends centrally along the blade body and through the first and second ends. The center opening is defined in the blade body and receives a drive shaft. The first aperture is defined in the blade body between the center opening and the first end. The first aperture receives a first projection. The second aperture is defined in the blade body between the center opening and the second end. The second aperture receives a second projection. The first aperture has a different shape than the second aperture. A centroid of each of the center opening, the first aperture, and the second aperture is substantially aligned with the longitudinal axis.

Power Tool Having A Variable Height Or Speed

US Patent:
2020024, Aug 6, 2020
Filed:
Jan 28, 2020
Appl. No.:
16/774785

James C. Ferrell - Elberton GA, US
Jonathan R. Feldkamp - Anderson SC, US
Dongyu Wang - Hendersonville TN, US
International Classification:
A01D 34/82
A01D 34/74
A01D 34/68
Abstract:
A power tool may have features for varying height or speed. The power tool may include a base chassis, one or more wheels mounted to the base chassis, and a handle frame attached to the base chassis. A slider assembly or support rail may further be included with the power tool to, for instance, aid in varying speed or height.
